Today marks the second anniversary of the end of the Brexit transition period. Tomorrow marks the 50th anniversary of the accession of the UK into the EEC, the predecessor of the EU. A lot has changed since then.
The UK remains deeply split over the wisdom of Brexit. Most Leavers still believe Remainers want to overturn a free and fair democratic vote. Most Remainers believe the referendum was a travesty of democracy.
Most Leavers believe that Remainers regard them as ignorant fools and xenophobes. Most Remainers resent being mocked and ignored by Conservative governments that have made minimal effort to placate them.
Opinion polls show support for Brexit diminishing. The UK government rejected a recent petition demanding that it hold a public inquiry into the impact of Brexit, suspecting a Remainer ploy to embarrass it.
There will be no further Brexit referendum. The UK could not rejoin the EU on the previous terms. The government should set up a commission to find ways to make Brexit work.

AR This is the Labour line. It's a fudge. Brexit is a historic blunder.

Stress exists on a gradient, with four mind states:
Red mind is the state of acute stress
Yellow mind is the state of being constantly stressed
Green mind is when we're pleasantly relaxed
Blue mind is when we access a state of deep rest

Strategies for shifting into a calmer state of mind:
— Don't try to solve problems that haven't yet happened
— Stop frowning
— Making lists of what stresses you can help
— Think of your stress as an asset
— Exercise is like a stress vaccine
— Tell yourself you are better than this stressful situation
— Smell the flowers or look out of the window
— Slow breathing to six breaths a minute
— Being grateful is good for the brain

AR Seems helpful.

A controlled fusion reaction generated more power than was used to kickstart it. The event fuels hope that fusion reactors can give us abundant, clean energy.
Fusion power will be a great example of what astronomer Martin Rees calls cathedral thinking, where multiple generations of coordinated effort are needed to solve a grand challenge.
The National Ignition Facility (NIF) was born out of the US nuclear weapons program. It was a way to test thermonuclear bomb design while avoiding banned detonations.
The NIF lasers put out just over 2 MJ of power, but the reaction on December 5 yielded a little over 3 MJ. The lasers needed 300 MJ to run, but fusion power became demonstrably possible.
To deliver commercial power with a design like NIF, you need to more. The demonstration fired once, for a few ns, then took hours to cool. A viable reactor must ignite repeatedly, reliably, and for long periods without maintenance.
When fusion reactors go commercial, the designers will be standing on the shoulders of many thousands of scientists and engineers.

AR The quest for practical fusion power is historic. Achieving it will herald a new age. It will be a huge step forward from the age of fossil fuel power. But we are still a long way from exploiting the full potential of solar power.

Rabbi Says Leave Russia Now

Stephen Burgen

Moscow's exiled chief rabbi Pinchas Goldschmidt resigned and left Russia in July after refusing to back the Russian invasion of Ukraine: "I believe the best option for Russian Jews is to leave."
Russian Jews have been emigrating for 100 years, first to Europe and the Americas and more recently to Israel. Today only about 165,000 Jews remain in the Russian Federation.
Goldschmidt: "There's a section of Russian society called the creacle, the creative class .. and I think it's safe to say a great percentage of those people have left Russia."
Goldschmidt recalls that Volodymyr Zelensky, who made no secret of his Jewishness, was elected president of Ukraine with more 70% of the vote.

The Year in Biology

John Rennie

Our memories are the cornerstone of our identity. Drugs to counter degenerative diseases have only marginal effects. Aggregations of proteins around cells are beginning to look like an almost universal phenomenon in aging tissues. Worsening problems with protein management may be a routine consequence of aging for cells.
Memories form when the neural activity behind experiences strengthens the synaptic connections between the neurons involved. The changes are physical records. We are learning how and where in the brain they reside. Biochemical mechanisms distinguish good memories from bad ones by flagging them with levels of neurotensin.
Even individual cells in developing tissues may carry some records of their ancestral history. These stem cells seem to rely on that stored information when faced deciding how to specialize in response to chemical cues.
Living cells first appeared some 3.8 billion years ago. Replicating molecule evolved into a throng of different replicators. Various molecules coevolved into competing hosts and parasites that rose and fell in dominance. The molecules started working together in an ecosystem. Early metabolism involving complex sets of energetic reactions might have arisen near hydrothermal vents.
A fertilized egg cell grows into an adult human body with upward of 30 trillion specialized cells. Chemical gradients guide cell navigation, but so do patterns of physical tension in surrounding tissues. Mechanical forces inside an embryo also help induce sets of cells to become specific structures.
The brain uses a lot of energy, but evolution has helped it cope with lengthy periods of food deficiency. When mice survive on short rations for weeks on end, their brains start to operate in a low-power mode. But this mode reduces the resolution of their vision by making visual signal processing less precise.
Chemical structures go a long way toward defining the smells we associate with various molecules. The metabolic processes that create molecules in nature also reflect our sense of the smell of the molecules. Neural networks that include metabolic information in their analyses classify smells more like humans do.
Isolated brain tissue in the laboratory can form organoids. A team implanted human brain organoids into newborn laboratory rats. The human cells integrated themselves and took on a role in smell. The transplanted neurons looked healthier than ones growing in isolated organoids.

Mathematical structures are interconnected. As we find new connections, the sprawl of subdisciplines shrinks. A deep geometric structure underlies the combinatorial properties of graphs.
We have found the most efficient way to pack spheres in 8D, and it minimizes the energy of a system in a variety of contexts. We also have a general theory of how liquids flow through porous media.
By a certain measure, the primes are the largest example of a primitive set. An infinite number of prime pairs differ by 600 or less, and an infinite number of primes lack a given digit.

Cryptographic protocols are based on the difficulty of various math problems. Secure one-way functions are possible only if a version of Kolmogorov complexity is hard to compute.
We can use quantum entanglement for secret encrypted communications. A fully entangled system would be impossible to describe fully. Systems close to being fully entangled are just as impossible to calculate.
Transformers excel at language processing and image classification. A transformer processes all its input data in parallel. New hypernetworks help us train ANNs fast. Embodied AI can now learn in responsive 3D environments.

Taiwan will extend its compulsory military service from 4 months to 12 months amid mounting military tensions with China. The Taiwan defense ministry says 71 Chinese air force jets and drones entered its air defense identification zone within 24 hours on Monday.
President Tsai Ing‑wen: "As long as Taiwan is strong enough, it will be the home of democracy and freedom all over the world, and it will not become a battlefield. Taiwan wants to tell the world that between democracy and dictatorship, we firmly believe in democracy. Between war and peace, we insist on peace. Let us show the courage and determination to protect our homeland and defend democracy."
Taiwan is shifting from a conscript military to a volunteer-dominated professional force. China's growing assertiveness toward the island and Russia's invasion of Ukraine have prompted debate about how to boost defense.
The American Institute in Taiwan welcomed the announcement on conscription reform: "The United States' commitment to Taiwan and steps Taiwan takes to enhance its self-defense capabilities contribute to the maintenance of peace and stability across the Taiwan Strait and within the region."

UK economy unprepared for invasion
The Times

Senior UK government officials say Britain is unprepared for the "catastrophic" economic consequences of a Chinese invasion of Taiwan.

Chinese Maritime Threat

The Times

China dominates international shipping. It could choke global trade in a conflict with the West over Taiwan, warns VUB professor Jonathan Holslag in an EU research paper.
Holslag: "Given the impact of the current war in Ukraine, it is crucial for Europe's security and prosperity to critically evaluate this vulnerability."
China is the largest shipbuilder in the world. The Chinese State Shipbuilding Corporation (CSSC) builds about 41% of all ships. China controls almost a third of all maritime trade, including 18% in containers, 12% in crude oil, and 13% in LNG.
Holslag: "China considers maritime power as an important building block of its national power and crucial for its national economic security. China has vast maritime power."
The Communist Party of China (CPC) has a grip on all big state-owned maritime companies, such as CSSC, China Ocean Shipping Company (COSCO), and China Merchants Group (CMG).
The CPC ensures that all merchant shipping is for dual military and civilian use. Ro‑Ro ferries are designed and used for military exercises and landings. Party commissars "erect an ideological fortress" on every ship.
COSCO party secretary Xu Lirong says China aims to control the entire supply chain including major transportation hubs and channels. COSCO has financial stakes in such European ports as Hamburg, Piraeus, Le Havre, Zeebrugge, and Antwerp.
Holslag compares Western dependency on consumer goods made in China with Chinese addiction to opium supplied by British imperialists.

Monsters of American Capitalism

Robert Reich

Capitalism is premised not only on greed but also on laws and norms that contain it. When avarice defines an era, laws and norms are no match for its monsters.
  Donald Trump took bogus deductions to reduce his tax liability to zero in 2020. All told, he reported $60 million in losses during his presidency while continuing to pull in big money. Trump is already synonymous with greed and the aggressive violation of laws and norms in pursuit of money and power. But when a US president celebrates these traits, they leach out into society like poison.
  Sam Bankman-Fried stands accused by the SEC of using customer money to fund his crypto empire. From the start, contrary to what FTX investors and trading customers were told, he diverted and used FTX customer funds to grow his empire. He may have committed one of the biggest frauds in US history. Yet until recently he was seen as a model for aspiring billionaires.
  Elon Musk and his maneuvers at Twitter might cause even the most rabid capitalist to wince. Shares in his other company Tesla are down 64% over the last year as analysts worry about its fate. He's even taking executive talent from Tesla to help him at Twitter. He's less concerned about laws and norms than about imposing his will on others.
These are the three monsters of American capitalism.

The Trump Committee

The New York Times

The hearings of the House select committee on the Jan 6 attack on the Capitol presented a disturbing account of Donald Trump's efforts to overturn the 2020 presidential election.
Through these hearings, Congress showed that the best answer to political violence lay in the rule of law, checks and balances, testimony given under oath, and careful bureaucracy.
The hearings made protecting democracy a significant issue in the midterm elections. The sustained attention on Trump's conduct in his final days in office is also valuable.
The Democrats and Republicans who served on the committee captured the attention of Americans who need to know about Trump's role in the events of Jan 6.

President Volodymyr Zelensky of Ukraine delivered an emotional wartime appeal to a joint meeting of Congress on Wednesday night: "Ukraine is alive and kicking. And it gives me good reason to share with you our first joint victory: We defeated Russia in the battle for minds of the world."
Zelensky pleaded for more military assistance: "We have artillery, yes, thank you. We have it. Is it enough? Honestly, not really." The money, he said, was not charity: "It's an investment."
Zelensky ended his speech by delivering an Ukrainian battle flag to House Speaker Nancy Pelosi, who in return handed him a framed American flag.
The American flag in his right hand, Zelensky jabbed his left fist into the air: "We stand, we fight, and we will win because we are united − Ukraine, America, and the entire free world. May God protect our brave troops and citizens. May God forever bless the United States of America. Merry Christmas and a happy, victorious New Year."
President Joe Biden: "We will stay with you for as long as it takes."

Volodymyr Zelensky was in Washington to thank Joe Biden and the American people for their support. The climax was his address to a joint session of Congress.
He stood at the same spot American presidents do when delivering the State of the Union address. "Against all odds and doom-and-gloom scenarios, Ukraine didn't fall − Ukraine is alive and kicking," he said, prompting one of many standing ovations.
Winston Churchill also addressed Congress in the Senate chamber on 26 December 1941. At the end of his speech, the chief justice gave a V for victory sign. A reporter: "The effect was instantaneous, electric. The cheers swelled into a roar."
Cheers turned to roars again for Zelensky when, in a nod to Churchill, he declared: "Ukraine holds its lines and will never surrender."

US Military Spending

The New York Times

Pentagon spending is rising. Congress is on track this week to approve a US military budget for FY 2023 of about $858 billion. If it does, the Pentagon budget will have grown at 4.3% per year over the last two years, even after inflation. US national security adviser Jake Sullivan says the war in Ukraine had exposed shortfalls in the US military industrial base that need to be addressed.
US military spending next year is on track to reach its highest level in inflation-adjusted terms since the peaks between 2008 and 2011, and the second highest in inflation-adjusted terms since WW2. More orders are coming in to US military contractors from allies in Europe and Asia too, as they decide to do more to arm up against rising global threats.

50 years on

Over a period of 12 days in December 1972, Operation Linebacker II saw more than 200 US B‑52 bombers fly 730 sorties and drop over 20 kilotons of bombs on North Vietnam. On December 17, the eve of the mission, US President Richard Nixon told his national security adviser Henry Kissinger: "They're going to be so goddamn surprised."
The "Christmas bombings" obliterated swathes of Hanoi and killed an estimated 1,600 Vietnamese. Some likened the horrors to the Hamburg raids of WW2. The flak was fierce, and 15 B‑52s were shot down.

Putin Destroying Russian World

In the Ukrainian city of Lviv, every student I talked with showed a total rejection not just of the Russian dictator or of the Russian Federation but of all things Russian.

Revulsion against Russia's neocolonial wars has extended to the whole broader notion of a Russian-speaking world.

Japan faces threats from North Korea and China. Its government will build up a system of defense that is not solely reliant on the US military, increase defense spending to 2% of GDP, and develop a counterstrike capability to hit enemy missile launch sites.
PM Fumio Kishida: "I will resolutely fulfill my mission as prime minister to protect and defend the nation and people in the face of a turning point in history .. My understanding is that the current capability is not sufficient."
China's repeated intrusions into the territorial waters around the Senkaku Islands pose a "challenge" but Japan and China must build a stable and constructive relationship.
China says Japan "seriously deviates from the basic facts, violates the spirit of the four political documents between China and Japan, willfully incites threats from China, and provokes regional tension and confrontation."
Japan aims to establish and expand a "multilayer network" with allies including the US, Australia, South Korea, India, and ASEAN nations.
Defense spending will increase to a total of ¥43 trillion ($313 billion) over the 5‑year period from FY 2023 to FY 2027. Including coastguard, infrastructure, and research spending, the budget will approach 2% of GDP in FY 2027.

Mathematically educated people are akin to the stem cells of a technologically advanced society. Their training and continued professional development are matters of national significance.
Mathematical thinking needs reverse thinking, understanding conceptual models rather than simply following algorithms, and cultivating the ability to see the field rather than just the ball. Informatics, what many call computer science, is the modern companion of mathematics.
The UK government recognises the need for more involvement of people with serious education and skills in mathematics and informatics. Mathematical education is also held back by the focus on testing and examinations at schools.

Fusion Power Breakthrough

The Guardian

Researchers at the US National Ignition Facility in California say their fusion experiments released more energy than was pumped in by the NIF lasers. This is hard evidence that stellar power can be harnessed on Earth.
The NIF was built to perform experiments that recreate, briefly and in miniature, the processes unleashed inside nuclear bombs. More usefully, the experiments are also steps toward mass rollout of clean fusion power.
To achieve ignition, the researchers fire up to 192 giant lasers into a little 1 cm gold cylinder containing a peppercorn-sized fuel pellet. The intense energy heats the cylinder to more than 3 MK and bathes the pellet in X‑rays.
The X‑rays trigger an implosion that causes the deuterium and tritium in the pellet to fuse. Each fusing pair produces a helium nucleus and a burst of energy. Deuterium is easily extracted from seawater, while tritium can be made from lithium.
In the experiment, researchers pumped in 2.05 MJ of laser energy and got about 3.15 MJ out, a sign that fusion reactions in the pellet were pouring out energy. But around 300 MJ was needed to power up the lasers.
Oxford physicist Justin Wark: "This result proves .. fusion in the laboratory is possible. However, the obstacles to be overcome to make anything like a commercial reactor are huge .. It is highly unlikely that fusion will impact on a timescale sufficiently short to impact our current climate change crisis."

Black Holes

Andy Ross

Black Holes, by Brian Cox and Jeff Forshaw, is a really good introduction to black hole physics. Bright schoolkids and science undergraduates will certainly enjoy it. The story starts with Newtonian black holes and goes up to the latest wacky ideas linking wormholes with entanglements and using quantum codes to weave the fabric of spacetime.
As you might expect for a book with the name Brian Cox on the cover and the man Stephen Hawking among its actors, the tone is light and informal. Many readers will enjoy its garnish of winking references to Douglas Adams, Monty Python, and beer, though Americans might miss mentions of Star Trek. More serious readers will be reassured by the steady slog past famous milestones to the advanced ideas toward the end.
More to the point, the hard ideas are well explained. One gets the clear impression that the authors thoroughly understand the maths of general relativity, the Kerr solution for rotating black holes, AdS/CFT duality, the holographic principle, entanglement entropy, the RT conjecture, the ER = EPR idea, and quantum error-correcting codes. Keeping up a breezy tone as they navigate this lot is good going.
Naturally, the story includes its share of equations. But these are presented without false modesty and clearly explained, so target readers will appreciate them. They're certainly easier to understand than the sort of word salads, replete with misleading metaphors, that too many popular writers get lost in. As Galileo said, maths is the language of nature, so lovers of physics need to meet the equations early.
Altogether, this book is a model of how to get such basic books right. The topic of black holes is exciting, so it provides a natural peg on which to hang the potentially dull stuff about, say, the history of thermodynamics or the details of Bell correlations and nonlocality. In short, well done, lads.

AR I must reconsider the holographic principle.

Nuclear Fusion Breakthrough

Matthew Sparkes

A nuclear fusion reactor has reportedly created more energy than was put into it.
Researchers at the Lawrence Livermore National Laboratory (LLNL) in California working on the National Ignition Facility (NIF) fusion reactor use lasers to create heat and pressure that turns deuterium and tritium into a plasma for fusion to occur.
In their experiment, the lasers output 2.1 MJ to produce about 2.5 MJ of fusion energy. A useful reactor would have to produce more energy than was initially put into the lasers, which the experiment did not achieve.
A viable commercial reactor is still likely to be decades away.

AR The NIF principle will be great for a starship drive.


Quantum Theory Pioneers

Gino Segrè

Tobias Hürter reaches back to 1900 and Max Planck's formula showing that energy is quantized into discrete packets.
A few years later, the young Albert Einstein develops his theory of relativity. We meet a young Werner Heisenberg in the 1920s, gazing at the dawn after thinking up the first formulation of quantum mechanics. Soon after his epiphany, Erwin Schrödinger produced the second formulation of quantum mechanics.
The fifth Solvay Physics Conference, a week-long meeting held in Brussels in October 1927, was attended by some 30 of the leading physicists of the time. Among them were the key players in the development of quantum mechanics, including Heisenberg and his friend and collaborator Wolfgang Pauli. The very shy Paul Dirac, even younger than Heisenberg, had already made major contributions and a year later would formulate QED.
The 1927 conference is where the most famous debate in modern physics began. In the previous year, Niels Bohr and Heisenberg had worked out the concepts they needed to comprehend the new theory, including wave−particle duality, complementarity, the collapse of the wave function, and the uncertainty principle.
The consensus was that Bohr and Heisenberg were right, Schrödinger and Einstein wrong.

American Hubris

Adam Tooze

In its later years, the British empire was haunted by fears of decline and dreams of rebirth. Jed Esty asks whether the United States has succumbed to the same malady.
Donald Trump aimed to Make America Great Again. For Joe Biden, America is Number One. This cock­eyed view of the world will be painfully familiar to Brits. It results in too much military spending and too little on education and infrastructure.

No-Nobel Mathematics

Thomas Fink

On Saturday, in Stockholm, Nobel prizes will be presented in physics, chemistry, and medicine, but not mathematics.
Science works when scientists spot patterns in the universe and describe them, whether in words, like Darwin's theory of evolution, or mathematically, like Maxwell's equations. They are then tested by experiment. Patterns that stand up to scrutiny are called theories.
A new breed of scientist known as theorists deduced patterns simply by mixing and matching old ones, without doing any experiments at all. But seeing patterns among patterns is only possible in fields whose patterns have been described mathematically.
Theoretical physicists and mathematicians unify disconnected fields, conceive entirely new subfields, and create the starting point of radical new technologies. Despite their value, theorists are neglected by governments. Research funding is biased against them.
Theorists feel compelled to conjure up patterns. They confer the benefit to mankind that Nobel sought to honour.

AR The Fields Medal is enough, thanks.


Heinrich XIII

Jeremy Cliffe

A German far-right group was apparently plotting a coup d'état. The group was gathered around Heinrich XIII, Prince Reuß of Greiz, who was to be head of state.
Heinrich XIII planned to negotiate with Russia and had approached Russian authorities, though no evidence exists of them responding. His group posed a genuine and violent threat to public order in Germany.
Investigators first learned of the plot in April when searching the home of a former paratrooper near Bayreuth and finding firearms and ammunition. The group was surprisingly far advanced in wargaming a coup d'état.
The 25 arrested on Wednesday will appear before the Federal Court of Justice in Karlsruhe. Many have links to the Reichsbürger scene, a fringe, anti-Semitic, monarchist movement that says the old German Reich never legally ceased to exist.

Look Back in Anger

Andrew Marr

The UK is badly governed and in a terrible economic mess. The basic problem is that we have become a low-wage economy in which millions of people are locked into unrewarding working lives.
This has been a simmering problem for ages. The end of the Cold War and a new phase of market-driven globalisation pushed wealth into London's financial market and made Britain a destination for capital and skilled labour.
We have been a low-wage economy, for most people, because we haven't been a high-productivity or high-growth economy. That's about education, investment in science and infrastructure, and the long-term incentives for business to invest more and disperse less to shareholders. It will take us a long time to recover.
Turning around the ship is going to be the next big social democratic project. It's going to require a much more assertive state, long-term investment, and a commitment to fairness on wages, which will require higher taxation.
The Brown commission's announcements are welcome, particularly the commitment to abolishing the House of Lords. A senate or second chamber seems a modest and thoughtful proposal. We need a corruption commissioner in Westminster and an end to the merry-go-round between corporate lobbying and political office. But exactly how economic devolution for the towns and cities can be achieved remains unclear.
What matters about the Brown initiative is less the detail than the basic assertion that there is an alternative and better way of doing things. But the anger will be with us throughout 2023.

AR Anger is better than despair.

Fixing British Politics

The more the economy fails, the more people lose trust. Despite the promise of 2016 that the people would take back control, millions feel ignored, neglected, and forgotten.
The Commission on the UK's Future is demanding a new economic and political settlement:
 We know doubling growth, increasing productivity, and creating the new well-paid jobs of the future will not come from trying to win a race to the bottom to attract low-paying jobs from abroad.
 We have identified employment hotspots across our towns and cities, in every region and nation, where homegrown inventions, entrepreneurship, and workplace skills can create new products and competitive companies.
 We need a new Westminster and a new Whitehall, and we need to disperse about 50,000 civil servants and a host of agencies out of London.
 We need clarity about the UK in a constitution that guarantees free universal healthcare, an end to poverty, a sustainable environment, and the defence of our security.
 We need a new agency to uphold proper standards in public life. A new second chamber should assume a new function to protect the constitution.
The time is overdue for the new constitution we propose.

Fix Broken Britain

Jon Danzig

The ten most deprived towns in England voted for Brexit. Leave voters considered that an "elite" in power cared little about those on the bottom rungs of society, who felt trapped. The elite were unaffected by austerity measures and seemed to thrive on them.
The slogan "Take Back Control" appealed to those voters because what they considered lacking in their lives was control. Their lives were going nowhere, they were stuck, and they felt unrepresented with their deep concerns.
The EU was not the cause of any of the problems facing the deprived and forgotten areas of Britain. But Brexiteers knew how to exploit them.
Leave campaigners stole the personal data of millions of those who fitted the right profile and targeted them with powerful messages. They told them EU membership was the cause of their lives feeling stagnant and that Brexit was the answer.
Leaving the EU has caused the UK severe economic pain. A lot of the pain was already there when the UK was a member. The Leave side wrongly accused the EU and migrants, but they weren't the cause.
We will need deep reforms in the UK before we can become a welcome candidate for EU membership again. Rejoining would not fix all the UK's problems. But Brexit has made the problems worse, including the current cost-of-living crisis.
A Rejoin party cannot win until the problems affecting Britain and poor Britons are fixed. These problems were not caused by EU membership and cannot be put right by EU membership. Fix broken Britain first, then rejoin.

AR Sad but true: First the revolution, then rejoin.




A Cosmic Twist


There is a chiral asymmetry in the cosmic arrangement of galaxies.
In the beginning, a repulsive inflaton field is thought to have inflated our universe rapidly. Quantum fluctuations in the inflaton field became variations in the large-scale structure of the universe we see today.
A chiral inflaton field may have interacted with the gravitational field to create more particles of one chirality than the other. Chern−Simons coupling would have created chiral density variations in the early universe. This could explain why our universe contains more matter than antimatter.
To discover that the galaxy distribution violates parity, researchers checked tetrahedral arrange­ments of four galaxies. They took a galaxy and looked at the distances to three other galaxies. If the distances increased going clockwise, they called the tetrahedron R; if otherwise, L.
To determine whether the universe has a preferred chirality, they repeated the analysis for all possible tetrahedra for a database of a million galaxies and compared the results to expectations based on parity conservation.
The real data show a 7σ level of parity violation.

A New Era in Europe

Olaf Scholz

For most of the world, the three decades since the Iron Curtain fell have been a period of relative peace and prosperity.
In 2007, Russian President Vladimir Putin called the rules-based international order a mere tool of American dominance. In 2008, Russia launched a war against Georgia. In 2014, Russia occupied and annexed Crimea. Step by step, Putin chose a path that took Russia further from a cooperative, peaceful order.
Russia's brutal attack on Ukraine in February 2022 then ushered in a new reality. Russia is causing unspeakable suffering in Ukraine. Millions of Ukrainian citizens have had to seek refuge in Poland and other European countries, a million of them in Germany.
Security in Europe will require a new strategic culture. A balanced and resilient transatlantic partnership requires that Germany and Europe play active roles. Germans stand with Ukrainians as they defend their country against Russian aggression.
NATO must credibly deter further Russian aggression. The EU and the transatlantic alliance are strong. Russia is facing unprecedented economic sanctions. Putin needs to understand that no sanction will be lifted should Russia try to dictate the terms of a peace deal.
All the G7 leaders have commended Ukrainian President Volodymyr Zelensky's readiness for a just peace that respects the territorial integrity and sovereignty of Ukraine and safeguards Ukraine's ability to defend itself in the future. We will not accept the illegal annexation of Ukrainian territory. Russia must withdraw its troops.
Putin wanted to divide Europe, but the EU has granted candidate status to Ukraine and Moldova and reaffirmed Georgia's future in Europe.
Our goal is an EU with over 500 million free citizens, representing the largest internal market in the world, that will set global standards on trade, growth, climate change, and environmental protection and that will host leading research institutes and innovative businesses in a family of stable democracies enjoying unparalleled social welfare and public infrastructure.
The EU is a political actor. We must close ranks on crucial areas in which disunity would make us more vulnerable. On immigration, the EU must devise a strategy that is pragmatic and aligns with its values. On fiscal policy, the EU has established a recovery and resilience fund that will also help address high energy prices.
Europe must continue to assume greater responsibility for its own security. History did not end with the Cold War.

AR Wise and balanced.

The Reality of Brexit

Jonathan Freedland

Brexit added almost £6 billion to British food bills in 2020 and 2021. Poor households were hit hardest. Brexit red tape added £210 to the average British household's grocery bill over the period.
Some 7 billion meals went to waste this year. Farmers cite a shortage of fruit and veg pickers as the key factor. Some 40% of NFU  members lost crops because they lacked the seasonal workers who used to come from the continent.
At the hospital, strain on the NHS has been exacerbated by Brexit, according to Nuffield Trust research. The trust says the situation in social care is urgent, with the halt in EU migration barring continental care workers from coming to the rescue.
At the airport, British holidaymakers now need to queue for hours where once they breezed through. At the ferry terminal, UK musicians who once earned a living performing on the continent now find Brexit has blocked their path.
Brexit will make Britain 4% worse off, with £40 billion less annual tax revenue for schools, hospitals, and the rest. Tory claims that Brexit will work out in the end ring hollow. Reality bites.

Brexit is a broken dream
Matthew Parris

The broken dream of Brexit is an unmentionable fact in Westminster. Careful politicians avoid confronting it. But they see the truth.
A trading nation living next to an immense trading bloc that remains by far its biggest trading partner will feel economic pressure to converge, reducing the barriers its imports and exporters face. That was the whole purpose of the single European market.
After 2016, the argument for soft Brexit faced the slogan: rule‑takers but not rule‑makers. The referendum directed the government to break the rules. Leavers proposed to make up for the hit to UK−EU trade by increasing trade with the rest of the world.
The American hope has faded. There are no good reasons to resist associate membership of the European single market.

Brexit is not working

The UK government must face facts:
  The current UK relationship with the EU is damaging the UK economy.
  The UK government must find ways to improve the current Brexit deal.

2  Develop a new policy and strategy on Europe,
3  Revisit agreements that are not functioning well.

Plasma Sailing to Alpha Centauri

New Scientist

A spacecraft crossing the boundary of plasma at the edge of our solar system could be boosted to high speed for interstellar travel. The craft would use an electromagnetic field as a solar sail hundreds of km across.
This sail would catch the plasma streaming outward at 650 km/s to some 90 AU beyond the Sun before meeting particles in interstellar space at the termination shock. The craft would pick up speed by tacking at this boundary.
Magnetic coils would kick the craft perpendicular to the solar wind with each tack. Two years of such dynamic soaring could accelerate it to extreme speeds, potentially up to 0.02c.

Dorset and Barbados

David Jones

Richard Grosvenor Plunkett-Ernle-Erle-Drax is an old Etonian and a former captain in the Coldstream Guards. Since 2010, he has been Conservative MP for South Dorset.
He owns a portfolio of companies and properties across England, lives in Chartborough House in an estate covering about 2% of Dorset, and is worth an estimated £150 million.
Drax has been named and shamed for omitting to declare ownership of his family's Barbados sugar plantation in the parliamentary register of members' interests. Civil rights activists backed by a Barbados special envoy are demanding that he pay compensation for the sins of his forebears.
Around 370 years ago, Sir James Drax pioneered the use of African slaves to cultivate his sugar plantation in Barbados. Drax Hall still stands there, and the plantation still employs local people. But the Drax heirs were enlightened compared with some plantation bosses.
The Sugar Barons by Matthew Parker describes the trials the slaves suffered. Those who survived the voyage across the Atlantic were paraded, naked and in chains, for auction in Bridgetown.
After an uprising in Barbados in 1675, more than 100 slaves were tried, 17 judged guilty, 6 burnt alive, and 11 beheaded. For an uprising in 1692, 42 slaves were castrated. At its height, this brutal system funded British crown coffers with the modern equivalent of over £500 billion a year.
Sir James Drax came from a humble Warwickshire family and had £300 when he sailed to Barbados. He learned to apply new methods of sugar production and prospered, with hundreds of black slaves. The British government later paid his heirs the equivalent today of some £500,000 to give them up.
Richard Drax is the seventh Drax heir to sit in the Commons and has been an ardent Brexiteer since before the referendum.

War in Ukraine

German chancellor Olaf Scholz urges Russian president Vladimir Putin to find a diplomatic solution to the Ukraine conflict as soon as possible.
The Kremlin says Putin told Scholz the German and western line on Ukraine was destructive and urged Berlin to rethink its approach.
Kyiv says peace talks are possible only if Russia stops attacking Ukrainian territory and withdraws its troops from Ukrainian soil.

World War III
Stephen Wertheim

The United States is entering an era of great power rivalry that could escalate to large-scale war.
The acute threat comes from Moscow. President Putin controls thousands of nuclear weapons, enough to destroy civilization many times over. Since invading Ukraine, he has threatened to use them.
Putin could plausibly act on that threat under several scenarios: if US or NATO forces directly enter the conflict, if he believes his rule is threatened, or if Ukrainian forces verge on retaking Crimea. The risk of Armageddon is the highest it has been since the Cuban missile crisis.
If Russia is not enough, US relations with China are in free fall. President Biden recalls the US commitment to defend Taiwan and vows to send US troops in the event of a Chinese invasion.
A war would likely last a long time and take many lives. China would have incentives to mount a massive attack to disable US forces stationed in the Pacific. Each side would be tempted to escalate. In a prolonged war, China could mount cyberattacks to disrupt critical American infrastructure.
A Chinese invasion of Taiwan would profoundly damage the US and global economy regardless of Washington's response. A yearlong conflict would slash US GDP by 5−10%. The gas price surge early in the Ukraine war provides only the slightest preview of what a US−China war would generate.

Quantum Computer Simulates Wormhole

New Scientist

A quantum computer has been used to simulate a holographic wormhole for the first time. Simulations like this may help us develop a theory of quantum gravity.
Maria Spiropulu and her Caltech team used the Google Sycamore quantum computer to simulate a holographic wormhole through spacetime with black holes at either end. They sent a qubit message through it.
In a real wormhole the trip would involve gravity, but the holographic wormhole uses quantum effects as a substitute. The message travels by quantum teleportation between two entangled particles.
Spiropulu: "The signal scrambles, it becomes mush, it becomes chaos, and then it gets put back together and appears immaculate on the other side."

A wormhole in a quantum computer

A team has implemented a wormhole teleportation protocol on a quantum computer. The experiment helps us understand the holographic principle.
Juan Maldacena discovered that anti‑de Sitter (AdS) spacetime and gravity correspond to properties of a conformal quantum field theory (CFT) on the boundary. He called it AdS/CFT duality. He found that a certain entanglement pattern involving two sets of particles is mathematically dual to a pair of black holes in AdS space whose interiors connect via a wormhole. He coined the slogan ER = EPR.
Daniel Jafferis conjectured that ER = EPR should let us design bespoke wormholes by tailoring an entanglement pattern. He developed the wormhole teleportation protocol. Others then showed that the traversable wormhole can be realized in a simple quantum system. Further work led to the holographic SYK model.
Two SYK models linked together can encode the two mouths of a traversable wormhole. To teleport a qubit from one system of particles to another, we rotate all the spin directions. In the dual space­time, this becomes a shock wave that kicks a qubit out of the wormhole.
Maria Spiropulu and her team simplified the wormhole teleportation protocol to run on the Google Sycamore quantum computer. The team ran the protocol and saw the signature.
The experiment may tell us nothing about our de Sitter (dS) universe. AdS has an outer boundary and dS space does not. The boundary is what makes holography possible.
Renate Loll: "It is rather tempting to get entangled in the intricacies of the 2D toy models."

Traversable wormhole dynamics on a quantum processor
Daniel Jafferis et al.
Nature 612, 51−55 (2022)

The holographic principle postulates that the description of a volume of space can be encoded on a lower-dimensional boundary. The AdS/CFT duality is the principal example. The Sachdev−Ye−Kitaev (SYK) model is a new realization of holography.
We invoke the holographic correspondence of the SYK many-body system and gravity to probe the conjectured ER = EPR relation between entanglement and spacetime geometry.
We construct a sparsified SYK model that we experimentally realize with 164 2‑qubit gates on a 9‑qubit circuit and observe the corresponding traversable wormhole dynamics. Our experiment was run on the Google Sycamore processor.

Titan of Logic

David Nirenberg

John von Neumann was born in Budapest in 1903 and died in Washington DC at the age of 53. In areas from set theory through quantum mechanics and the computing revolution to game theory and his late work, he reduced complex problems to simple logic.
He was born into a prosperous Jewish family. At the University of Budapest, he was 17 when he published his first paper. In 10 pages, he deployed set theory to articulate a definition of ordinal and cardinal numbers that remains standard today.
His doctoral dissertation in 1925 axiomatized set theory. In 1928, he developed a theory of games. He used the insights decades later to create a computer architecture that became a standard. He later defined logical machines that could replicate virally.
Von Neumann also worked in the social sciences. His 1944 book with Oskar Morgenstern, Theory of Games and Economic Behavior, aimed to identify the problems of economic behavior with the mathematical notions of games of strategy.
Von Neumann forgot a basic truth about logic and life. Every mathematical rendering of objects that are not purely mathematical is a simplification. In 1955, he said the only way avoid global catastrophe is to rely on human qualities.

Russia Wins by Losing

Timothy Snyder

My friends in Kyiv urgently need anti-drone defense. The Russians are trying to freeze millions of people out by destroying the power grid.
Ukrainians have no electricity and no water. Their extraordinary physical courage and ethical commitment reminds me of Leszek Kołakowski's definition of an ethical act as something more than anyone could have expected of you.
I met Volodymyr Zelensky in September. We talked mostly about philosophy and the meaning of freedom. He said freedom sometimes means having no choice, like when he decided to stay in Kyiv when the invasion began in February.
The Kremlin narrative is wrong. When you answer propaganda directly, you get into an unpleasant dance with the propagandists. The history of Ukraine is more interesting than the propaganda.
Many expected Ukraine to collapse within days after Russian tanks rolled in. Things that seem technical and objective, like the evaluation of a war, can often depend upon subjective things, like whether we believe a country is real.
To become a normal European country, you need to lose your wars. Russia needs to lose this war. The whole invasion is a substitute for the internal changes Russia needs to make. Russians still see negotiations as a pause to regroup and attack again.

The Inward Turn

Matthew Syed

To share is now to talk with others about one's thoughts, feelings, or experiences.
For most of the period since the scientific revolution, the emphasis was on engaging with external reality to solve collective problems. Shared empirical standards and objective conceptions of truth sat behind the transformation in economics and technology that created the modern world.
In recent decades, there has been an inward turn, from the outer world to the inner self, from external reality to subjective feelings. We used to take photos to remember events or vistas. Now we take selfies.
The inward turn might help to explain a transformation in political debate. If my focus is inwardly directed and my self-esteem requires me to be right, I may be more disinclined to engage with other points of view, more likely to feel offended when someone disagrees with my opinions.
The danger comes when lived experience trumps data on matters of fact. The inward turn takes us away from shared reality. Academic subjects that prioritise feelings above data are now being taught in UK universities and even schools.
Brexit illustrates the inward turn. Leave voters use subjective feelings to justify their decision, even in the face of objectively worsening evidence. We may be poorer, they say, but we have control over our economy and our borders. The feeling of control has left us adrift among external events.
When truth becomes subjective, we become marooned on solipsistic islands. Descartes said we cannot be certain of anything beyond ourselves. Wittgenstein said language, science, and truth can emerge only when we transcend the self and connect meaningfully with others.
Left unchecked, the inward turn could one day destroy our civilisation.

AR Wise words.

The Meaning of Thought

Philosophy is the most general way of thinking about our thinking. It is more general still than mathematics, which is itself a form of language and thought that serves as a foundation for the natural sciences and technology ..
Naturalism is the view that all genuine knowledge and progress can be reduced to a combination of natural science and technological mastery of the survival conditions of human beings. Yet this is a fundamental error, a dangerous delusion, which haunts us in the form of various ideological crises ..
New Realism is my proposal for overcoming the basic intellectual errors to which we continue to succumb, much to the harm of our society and our own humanity.
I will introduce you to the notion that .. our thought is a sense, just like sight, taste, fearing, feeling or touch. Through thinking, we touch a reality accessible only to thought .. I argue the case for giving our thought a new meaning, in the sense of a new direction.

The French were in denial right up until the last moment. The German view was at one stage that if it were going to happen, which would be a disaster, then it would be better for the whole thing to be over quickly, and for Ukraine to fold. I thought that was a disastrous way of looking at it.
Soon everybody saw that you couldn't negotiate with Putin. I pay tribute to the way the EU has acted. They have been united. The sanctions were tough. If Ukraine chooses to be a member of the EU, they should go for it.
President Zelensky is a very brave guy. I think the history of this conflict would have been totally, totally different if he hadn't been there.

Britain: Poverty Everywhere

Paul Mason

Jeremy Hunt salvaged the British economy by borrowing.
Public sector funding will be eaten both by inflation and by spending cuts. Families will see their living standards fall. Ahead loom the hardest two years in living memory and the sharpest GDP decline in Europe next year.
The Conservative party has failed as a trustworthy steward of government. Hard Brexit has turned it into a Utopian cult. Business investment has cratered, and trade is no longer driving growth.
The Conservatives have presided over a disaster. Free market growth ran on cheap credit. Cheap credit crashed the banking system. Austerity eroded social solidarity. Brexit created trade friction. Tories doubled down on economic nationalism, crass xenophobia, and legalized corruption.
There is poverty everywhere in Britain.

AR Mason isn't exaggerating: it's shocking.

UK Low Prospects

Financial Times

The UK economy is set to be the worst performer in the G20 bar Russia over the next two years, says the OECD. Its latest economic forecasts UK GDP will fall 0.4% in 2023 and rise 0.2% in 2024, a longer and deeper downturn even than the forecast for Germany, whose economy is vulnerable to high energy prices. OECD acting chief economist Alvaro Santos Pereira says the economic adjustment under way in the UK has compounded concerns about low UK productivity growth.

Britain still needs the EU
Rafael Behr

The UK needs a functional relationship with the EU. But dependency on the single market offends the sacred core of Brexit. Tory hardliners reacted with fury to rumors that the government was mooting a Swiss model.
Ignorance or misrepresentation of the single market was the binding thread in a triple fallacy in the economic case for leaving the EU:
  Europe was dismissed as the dotard of the global economy
  Britain would retain the benefits of the single market anyway
  The cost of regulatory compliance with EU rules was too great
Rishi Sunak cited all three in an article explaining his decision to vote leave in 2016. Now we know Brexit is a drag on UK economic performance. That fact is taboo, so it leaks out as a rumor about a Swiss model.

AR Ah, Brexit ..

World Still on Brink

Fiona Harvey

The COP27 final agreement offers poor countries financial assistance for the rescue and rebuilding of vulnerable areas stricken by climate disaster. Other commitments were dropped from the deal, at the behest mainly of Saudi Arabia and other petro-states.
COP26 UK president Alok Sharma tried at COP27 to go further but failed: "Emissions peaking before 2025 .. Not in this text. Clear follow-through on the phase down of coal. Not in this text. A commitment to phase out all fossil fuels. Not in this text."
UN secretary general António Guterres: "Our planet is still in the emergency room. We need to drastically reduce emissions now."

No to Swiss Model

Rishi Sunak

Under my leadership, the UK will not pursue any relationship with Europe that relies on alignment with EU laws.

  On migration, we have proper control of our borders.
  On trade, we can open up our country to the world's fastest growing markets.
  On regulation, we need regulatory regimes that create the jobs and growth of the future.

The Brexit Disaster

Martin Fletcher

Support for Brexit nationwide has fallen to a record low, with 56% saying we were wrong to leave and a mere 32% saying we were right. As the economy implodes and the UK makes common cause with the EU in the war against Russia, Brexiteers are losing the argument.
Economic and business leaders are becoming more vocal. The CBI urges the government to seek better relations with the EU. The OBR says Brexit has had an adverse impact on British trade. Bank of England governor Andrew Bailey says Brexit is damaging the economy.
Paris has overtaken London as Europe's largest stock market. India has overtaken Britain to become the world's fifth largest economy. Asylum seekers cross the Channel to the UK in record numbers. The NHS is close to collapse. The US trade deal never happened.
Rishi Sunak and Jeremy Hunt know all this and are changing course. They are considering a relaxation of post-Brexit immigration limits. They are seeking rapprochement with the EU and Ireland to resolve the dispute with Brussels over the NI protocol.
A Conservative prime minister called the 2016 referendum. A Conservative prime minister led us out of Europe. Conservative zealots forced the hardest possible Brexit. The Tories inflicted on Britain the greatest act of economic self-harm in living memory.

Britain Eyes Swiss Model

The Sunday Times

Senior government figures are planning to put the UK on the path toward a Swiss model for relations with the EU, with more liberal EU migration, payments to the EU budget, and a greater role for the ECJ in the relationship.
Chancellor Jeremy Hunt: "I think having unfettered trade with our neighbours and countries all over the world is very beneficial to growth. I have great confidence that over the years ahead .. we are able to remove the vast majority of the trade barriers that exist between us and the EU."
Former Brexit negotiator Lord Frost: "Any approach requiring the UK to align with EU rules to get trade benefits, whether as part of a Swiss-style approach or any other, would be quite unacceptable."
Tory ERG hardliners fear the government will give ground to resolve the row over the NI protocol. A deal could see the EU drop most of its checks on goods passing between GB and NI if the UK takes a less ideological position on the role of the ECJ in NI.
A Downing Street source: "Rishi wants to get this sorted as quickly as possible. There's definitely a deal to be done .. He's not going to be giving up stuff that he and the party would not be happy with him giving up."

UK−EU Relationship

Helene von Bismarck

The relationship between the UK and the rest of Europe has stopped getting worse. In the sad world of UK−EU relations, this is progress.
The change is due to the threat to European security. Putin's war against Ukraine has rendered a central narrative for Brexit untenable. Until then, the "will of the people" demanded leaving the EU to go for Global Britain.
The UK remains primarily a Euro-Atlantic power. When war broke out on the continent, Britain stepped up its military support for Ukraine. The war and the resulting energy crisis show it is impossible to escape geography.
Politicians and officials from the UK and Europe now meet much more frequently than they have in years. This helps rebuild trust and connections. But the improvement will be limited while the UK remains outside the EU.
Along with NATO, the EU is the main organization countering the threat from Putin's Russia. All Europeans should stand together.

Quantum AND Gate

Charles Q Choi

Quantum computers require that all their logic operations be reversible.
The NOT operation is reversible, but the AND gate is a challenge: A workaround uses an ancilla qubit for each AND gate to hold the data to reverse the operation.
Present quantum computers run on noisy platforms with only a few qubits and are prone to errors. It would be hard to design and build hardware for extra ancilla qubits.
Chinese researchers have made a new quantum AND gate with no need for ancilla qubits. Its qubits can encode a third state holding the data to reverse the operation.
The researchers ran their quantum AND gates on a superconducting quantum processor with tunable-coupling architecture and used them to make Toffoli gates.
Quantum computers with Toffoli gates are functionally complete.

UK Recession

UK living standards are set for their biggest fall in six decades. The UK economy will regain its pre-pandemic level only by the end of 2024. UK growth problems remain chronic.

Our Typical Cosmos

Charlie Wood

We think space inflated rapidly just after the Big Bang. To explain its gentle growth ever since, we guess our universe is just one among many in a multiverse.
A new calculation suggests our universe is the way it is because other options are extremely improbable. We calculate the entropy of our universe using a path integral technique that reveals a link with thermodynamics.
Thermodynamics describes a system of many parts as being in a macrostate and each specific configuration as a microstate. The number of microstates behind a macrostate defines its entropy. The higher the entropy of a macrostate, the more likely it is.
In thermodynamics, we add up all possible configurations of a system. And with the path integral, we add up all possible paths a system can take. But thermodynamics deals in probabilities, which are positive numbers, whereas the path integral assigns a complex number to each path.
We use math. Transform time from t to it (a Wick rotation), and in the path integral the complex numbers become real probabilities. Replace t with the inverse of T (temperature) to get a thermodynamic equation.
A black hole has entropy proportional to the area of its event horizon. A path integral adds up ways spacetime can bend to make a black hole. Wick-rotate the black hole by setting t to it and see that in the imaginary time direction, the black hole periodically returns to its initial state. This periodicity lets us define its temperature and entropy.
Wick-rotating an empty, expanding de Sitter spacetime with a horizon, we find that a de Sitter universe has an entropy. To define it, start at a center, add a surface between the center and the horizon, then shrink it until it reaches the center and disappears, to show that de Sitter entropy is proportional to the horizon area.
Adding radiation and matter to de Sitter spacetime still lets us Wick-rotate the universe. Looking at the expansion history of a realistic class of universes gives us a better equation for cosmic entropy. The calculation for a universe filled with matter and radiation give us a much larger number of microstates, proportional to volume and not area.
Almost all the microstates look like our universe.

AR So much for the holographic universe!

2022 November 16


Rafael Behr

American democracy had a near-death experience with Donald Trump, and the Conservative party went along with him. The British right slid into sycophantic orbit around Trump, far beyond a basic duty of maintaining transatlantic relations.
The two countries separated by an ocean are culturally dissimilar, even when their politics are in sync. One big difference is that Trump could be removed from office by operation of the normal electoral cycle. Britain is stuck with Brexit as a legal fait accompli.
Within two years of the deal being signed, its author was revealed to be a congenital liar and evicted from Downing Street. But the exposure of Boris Johnson as a serial political fraudster did not undo his biggest fraud.
The pretense that it was anything else is getting harder to sustain even for Tories who keep the Johnsonian faith. While trade realities are battering the economics of Brexit, Vladimir Putin has stripped bare its strategic folly with his war in Ukraine.
The Kremlin pumps money into movements that destabilize western democracies. As a project intended to disrupt the EU, Brexit was its sort of mission. Too many Tories were enjoying the dance to ask who was clapping along or paying the piper.
The British return to diplomatic sobriety is welcome if it means an end to foreign policy drunk-driving. But Tories were at the wheel when the UK was steered into a ditch.

Sean Carroll

We live in spacetime. Slicing it up into space and time is merely a useful human convention. We can better understand this by seeing what a unified spacetime implies.
The theory of electromagnetism assigns a special role to the speed of light. To understand this, Albert Einstein came up with a new conception of space and time in his theory known as special relativity.
He posited that the speed of light is an absolute speed limit and that everyone measures that speed to be the same, no matter how they are moving. Special relativity is the theory of a flat spacetime.
In relativity theory, an event is a single point in the universe, specified by locations in both space and time. Think about a journey between events A and B and ask how much time elapses between them.
Time is both a coordinate on spacetime and the duration you experience going from A to B. You can measure the duration by a clock you carry with you. This is the proper time along the path, and it depends on the path you take.
In space, a straight line describes the shortest distance between two points. In spacetime, a straight path yields the longest elapsed time between two events. That flip distinguishes time from space.
A straight path in spacetime is both a straight line in space and a constant velocity of travel. We can go between A and B in a straight line at constant velocity, or we can zip back and forth.
Straight paths in spacetime take the longest possible time. Paths of greater distance take less proper time. Einstein saw that.

AR As clear and simple as can be.

Earth Hosts 8 Billion Humans

The Times

The UN projects that today the human population on Earth will pass 8 billion.

The Guardian

Climate change is a global problem. But many wealthy nations are reinvesting in oil and gas, failing to cut emissions fast enough, and haggling over aid to poor countries.

The Great Filter

The Times

Threats such as nuclear war, climate change, and pandemics could finish off humanity before we discover other intelligent life. This may explain why we have still not met any extraterrestrials.
CalTech astrophysicist Jonathan Jiang et al: "We postulate that an existential disaster may lay in wait as our society advances exponentially toward space exploration, acting as the Great Filter: a phenomenon that wipes out civilizations before they can encounter each other, which may explain the cosmic silence."
Enrico Fermi posed the Fermi Paradox in 1950 when he pondered not meeting space aliens and asked: "Where are they?"

Poland and Ukraine

Anna Gromada, Krzysztof Zeniuk

Democracies want Ukraine to win. Autocracies want it to lose. But the real world is not so binary. Democracies are divided into English-speaking, western European, and eastern European.
Poland and the Baltic countries want Ukraine to win. This would soothe an old angst. Over the past 600 years, Russia and Poland have waged more than a dozen wars.
Victory in Ukraine would probably spill over into regime change in Belarus. A united region across eastern Europe, with the human and economic capacity of more than 100 million citizens, could offset the dominance of the old Rhineland in the EU.
Kremlin rhetoric treats Ukraine as a repository of Slavic peasant folklore. In fact, Ukraine hosts swathes of unexploited natural resources, a potential for green electricity, fertile soils, a space and aviation industry, and political leaders who command respect across Europe.
Tapping into that potential requires economies of scale, transparent institutions, and capital investments. Curbing corruption and the power of the oligarchs is very much on the agenda of the Zelensky administration. With victory, investment money would flow.
Poland and Ukraine are much poorer today than France and Germany. But the US is already pumping money and technologies into eastern Europe. In return, it expects influence and clarity on China.
Western Europe once had Russian energy, Chinese markets, and American security. Now the first pillar is gone and the second may be the price to pay for the third.
France and Germany currently endorse a policy of strategic autonomy for Europe. Putin has pushed the goal of a Eurasian union stretching from Vladivostok to Lisbon. Both strategies share an aversion to Anglo-Saxon dominance in Europe.
Many Americans seem to hope that a Russia standing on its feet can eventually pivot against China. In eastern Europe, this idea is greeted with horror. It has been tested too many times with Putin.
All major Polish parties support Ukraine. They want to see Ukraine emerge from this war as a star and Poland as the undeclared winner.

AR This perspective looks good to me.

Crowds of euphoric residents lined the streets of Kherson today waving Ukrainian flags as their troops rolled into the city after eight months of brutal Russian occupation.
Kherson was the only provincial capital Russia had seized since the start of the war. Its loss is the most embarrassing defeat for Putin since he began his invasion of Ukraine.
Celebrations broke out across Ukraine on Friday after the Russians began to flee. In his nightly video address President Zelensky hailed the recapture of the city as a "historic day" and promised to restore medicine supplies and communications as soon as possible.
The Russian military presence just across the river poses a continuing danger. Putin's army blew up the only road bridge across the Dnipro to prevent a Ukrainian pursuit.

Lattice Cryptography

Leila Sloman

Quantum hackers could decode many of our present cryptography schemes.
Present schemes rely on an asymmetry between multiplication and factoring. Any computer can quickly multiply two numbers, but it may take ages to factor a big number into its prime constituents. This makes secrets easy to encode but hard to decode.
Factoring is vulnerable to quantum hackers. Lattice cryptography uses another set of mathematical operations that are easy to do but hard to undo.
Imagine Alice has a lattice. She asks Bob to name 10 of its points but gives him just 2 points. Adding or subtracting any 2 points on a lattice gives another point in the lattice, so Bob adds the 2 points or multiplies them by integers and then adds them, or some combination of these, in 8 different ways to get 10 points.
Alice now gives Bob the same 2 starting points and asks him if some (xy) is on the same lattice. To answer, Bob needs to find the combination that gives (xy), which is much harder. That asymmetry underlies lattice cryptography.
Lattice cryptography has countless nuances and may have a fatal flaw.

Maria Popova

In Conscious, Annaka Harris examines the illusory nature of the self: "The idea that 'I' am the ultimate source of my desires and actions begins to crumble .. It seems much more accurate to say that consciousness is along for the ride."
On conscious causation: "Consciousness seems to play a role in behavior .. the fact that my thoughts are about the experience of consciousness suggests that there is a feedback loop of sorts and that consciousness is affecting my brain processing."
On panpsychism: "Ascribing some level of consciousness to plants or inanimate matter is not the same as ascribing to them human minds with wishes and intentions like our own .. it seems quite hard for us to drop the intuition that consciousness equals complex thought .. if a version of panpsychism is correct, everything will still appear to us and behave exactly as it already does."
On a challenge to psychism: "For many scientists and philosophers, the combination problem presents the biggest obstacle to accepting any description of reality that includes consciousness .. the obstacle we face here .. seems to be a case of confusing consciousness with the concept of a self."
On merging brains: "If two human brains were connected, both people might feel as if the content of their consciousness had simply expanded, with each person feeling a continuous transformation from the content of one person to the whole of the two, until the connection was more or less complete."
We consider the inconceivable impossible, but we can expand the possible until it becomes real.

Putin's War

Lawrence Freedman

Ukraine is determined to resist the Russian invasion. Putin cannot win and must give up on his attempt to do so. Ukraine cannot accept a Russian victory.
Russia does not admit it is the aggressor or is obliged to withdraw from occupied territory. A grand bargain is unlikely while both sides hope they can improve their positions. Even if the outlines of a deal could be designed and there was sufficient goodwill, turning it into a treaty would be hard.
Putin has no interest in bringing the war to a quick end if this means failure to achieve his key objectives. Any settlement he would accept is not one that Kyiv or the West could agree to. For him, the issue of Crimea is not even up for discussion. He also refuses to discuss the legal status of the four provinces he has annexed. He demands that Zelensky accepts they are forever Russian.
Putin needs to avoid defeat. If he admits failure, his judgement will be shown to be flawed and he will be vulnerable. To stay in power, he needs Russia to stay in the war.
Any deal will be a loss for Putin. Any that ends the fighting will be followed by a reckoning. So long as the war continues, he is protected by patriotism, wartime censorship, and control of dissent. Without the war, his folly will be exposed.
If Ukraine is denied victory, Putin can hope it will buckle under fire. He only wants peace on his terms. A peace that acknowledges Ukrainian sovereignty and territorial integrity begs the question of why he fought the war.
Ukraine can only offer a deal that requires Moscow to withdraw from occupied territory. This may need a change at the top in Moscow.

US Midterm Elections

The New York Times

US midterm elections are often seen as a referendum on the party in power. But voters need to consider the intentions of the party that hopes to regain power.
The next Congress will count the electoral votes in the presidential election in 2024. Some Republicans sought to overturn the results of the 2020 election.
Some Republicans embrace violent extremism. The 2022 elections are an opportunity for Americans to defend the integrity of US elections.

Another civil war?
Barbara F Walter

A civil war could happen again in the US. Militias spread around the country would fight to weaken the federal government and intimidate minorities and opponents.
A civil war starts when sustained violence by extremists has become the norm. Two factors raise the risk of civil war: ethnic factionalism and anocracy, when a government is neither fully democratic nor fully autocratic.
A group may resort to violence when it was once politically dominant but is losing power. Whites will be a minority of the population by around 2044. The result will be increasing resentment and fear at what lies ahead.
US democracy declined between 2016 and 2020. Since January 6, 2021, the US has failed to strengthen its democracy. The Democratic party cannot reform the political system, and the Republicans no longer want to.

Heading toward civil war
Stephen Marche

The US is headed toward civil war. The US is vulnerable because trust in its institutions is in freefall. The gulf between the political system and the popular will is widening.
The US electoral system depends on good faith. Refusal to accept electoral outcomes can result in a contested election. The right is prepared for this eventuality.
The US legal system has devolved from a truly national institution to a spoil of partisan war. This is a classic prelude to civil war. Neither party can fix America.

Another American conflagration
Christopher Sebastian Parker

America is rushing headlong into another civil war. The first civil war turned on racism. Throughout history, US political identity has been driven by positions on race.
Today, 4 in 5 Republican voters are white. Many want to take drastic measures to maintain white supremacy. Democrats see MAGA Republicans as an existential threat.
Violence results from an election that can shift power, partisan division based on identity, a winner-take-all voting system, and a lax approach to violence. America has them all.
A civil war with terrorism, guerrilla war, and ethnic cleansing will be waged from sea to shining sea. Racism will lead to another American conflagration.

During his visit, German chancellor Olaf Scholz prompted Chinese president Xi Jinping to say China rejects "the threat or use of nuclear weapons" with regard to Ukraine. China has never positioned itself so clearly. Russian warlord Vladimir Putin can see this as a red line.
After this first visit trip by a G7 head of government to the People's Republic since the beginning of the pandemic, a Chinese statement said "bilateral relations will continue to move in the right direction" as long as both sides respect each other and seek common ground.
Shenzhen Daily: "Germany is trying to prove that it will no longer be a lackey of the United States."
Global Times: "The US is not in a position to dictate Sino-German economic cooperation."

Xi, Scholz to expand pie
China Daily

China and Germany have reaffirmed their commitment to stabilizing and consolidating bilateral ties as well as promoting China−Europe cooperation, and vowed to expand the "pie" of their shared interests and work together to uphold regional and global peace and security.
On the Ukraine crisis, President Xi Jinping urged the international community to support every effort to help peacefully resolve the crisis, oppose using or threatening to use nuclear weapons, and make efforts to ensure the stability of industrial and supply chains.

AR So far so good.




Higgs and Our Universe

Toyoko Orimoto

The Higgs boson could help us discover new physics. In the standard model, elementary particles derive their masses from their interactions with the Higgs field. This includes the Higgs, so deviations from expectations would hint at new physics.
We can probe this via Higgs boson pair production. The LHC produces Higgs pairs at too low a rate to help, but if the standard model is wrong, so too may be its rate of pair production. If extra dimensions of spacetime exist, Higgs pair production could be enhanced.
The extra dimensions could explain the enormous differences in strength between gravity and the other forces. In the theory of warped extra dimensions, there are two branes, one our 3D world and the other where gravitons are unconfined. Gravitons permeate the bulk space between the branes, diluting gravity and warping the bulk space.
Producing more double Higgs bosons at the LHC could provide evidence of gravitons. Massive gravitons would decay to Higgs pairs and then to other particles.
Higgs pair production may also offer a window into the eventual fate of our universe. The vacuum state of our universe teems with virtual particle−antiparticle pairs popping in and out of existence. The Higgs field has a non-zero vacuum expectation value, filling the vacuum with Higgs bosons.
The Higgs potential is shaped like the bottom of a wine bottle. In our universe, a marble dropped into it rolls down to a spot that may not be stable. Quantum fluctuations could tunnel our universe into a different state, with new physics.

AR All this seems rather speculative.

Discovering Alien Life

Joshua Sokol

When Lisa Kaltenegger was asked to check some exoplanets that may have liquid water on their surfaces, she started running climate models and found they may well have water. This year, she was asked to help understand the planet SPECULOOS‑2c.
Our best chance of finding other life in the cosmos may be to detect biosignature gases in exo­planetary atmospheres. With the James Webb Space Telescope (JWST) now in service, we can try.
To sniff an exoplanetary atmosphere, we look for planets that transit in front of their star. During a transit, some of the starlight shines through the planetary atmosphere and changes the stellar spectrum. Spectral analysis reveals the chemistry.
Discoveries of rocky planets with the potential for liquid water remained scarce until the Kepler era. Kepler showed they are common, but the ones it found were too far away for good studies.
JWST would see only tiny signals from atmospheric gases during each transit, so good results would take years. But we can seek Earths in close orbits around red dwarf stars, where atmospheric signals are not lost in starlight and transits are more frequent.
In 2017, we found seven rocky planets around the red dwarf star TRAPPIST‑1. This year, we found the SPECULOOS‑2 system. These stars are close, dim, and red. They each have multiple rocky planets that transit.
Kaltenegger uses a climate model to analyze the evolution of alien atmospheres. Running it for SPECULOOS‑2c lets us predict what JWST might see. JWST will also view the TRAPPIST‑1 planets.

AR We're making good progress.

Save Britain or Save Brexit

Peter Mandelson

Britain needs a stable and competent government that restores standards and integrity in public life and offers direction and purpose.
Britain is now lagging at the bottom of the league table of G7 economies in growth, productivity, investment, and real wages. The mounting effects of Brexit are becoming clearer.
The prime minister must put the UK need to work with the EU before any desire to seek confrontation with Europe at every turn.
He cannot confront the challenges facing Britain without facing up to our economic and trade choices and the importance of building a stable relationship with the EU.
He cannot make Brexit work without revisiting the terms on which we left the EU. A hard Brexit has had devastating effects on British trade, competitiveness, prices, and growth.
He cannot lift UK trade and growth without forming a better relationship with the EU. UK trade in goods with Europe has become too cumbersome, too costly, too bureaucratic, and too slow, and is becoming a major drag on our growth rate.
Growth forecasts for Britain in coming years indicate no improvement. Spending on public services will be further squeezed. We will not be able to defend ourselves as we would like. We will lose influence in the world.
Labour has let the Conservatives rule without effective challenge for most of the last decade. Labour is not going to reopen the Brexit decision, but nor should it be held hostage by it.
We need to turn the page and begin the next chapter in our national story.

China Loses America

Thomas L Friedman

President Xi Jinping has reversed the steady integration of China's economy with the West. Our world will become less prosperous, less integrated, and less geopolitically stable. Four signs:
1  When China joined the WTO, Chinese industries copied or stole IP from Western firms that built factories in China. The firms have responded by going ABC: "Anywhere but China."
2  President Xi has been elected to a third term on a platform pushing Marxism and ideology over markets and pragmatism.
3  A more aggressive Chinese foreign policy is trying to dominate the South China Sea, frightening Japan, South Korea, Vietnam, India, and Taiwan.
4  Instead of importing Western vaccines against Covid, China is relying on lockdowns and the new tools of a surveillance state.
Global supply chains require trust between partners. Xi has lost it.

Climate Warnings

New Scientist

New climate reports remind us that greenhouse gas concentrations are rising.
The World Meteorological Organization says atmospheric concentrations of carbon dioxide, nitrous oxide, and methane hit a record high in 2021 and continue to rise in 2022.
Atmospheric carbon dioxide has caused about two-thirds of global warming since 1750. Methane registered the largest single-year increase since records began 40 years ago.
The greenhouse gases are having increasingly severe climate impacts: 2022 brought extreme heatwaves, storm surges, and severe flooding to many parts of the world.
Scientists say that of 35 planetary vital signs, 16 are at record extremes and flashing red on the climate dashboard. They say we face a climate emergency.
Two UN reports confirm we are still on course to exceed the Paris Agreement target of an average global rise of 1.5 K or less. Climate scientists say any warming above 1.5 K risks triggering severe and irreversible changes to ecological systems.
The UN says existing national plans would see carbon emissions fall by 3.6% by 2030 compared with 2019 levels. We need a 43% drop to meet the 1.5 K target. The plans put us on course for about 2.5 K of warming.
At COP26, participants agreed to submit bolder proposals to cut emissions within a year to meet the Paris Agreement goals. But only 26 of them have done so. Together the updates cut 2030 emissions by less than 1%.
The COP27 hosts will ask countries to cut emissions faster.

AR One is not optimistic.

Growing up among mathematicians helped me develop a resilience for solving problems. I started to like mathematics in university. When I started graduate work with Yakov Sinai, who studied probability, the first paper he gave me to read involved physics.
I came to the United States right after getting my PhD from Moscow State University in 1991. I was not a very successful graduate student. But I had the resilience to continue, and I finished my PhD with a total of seven papers.
I study models that govern the behavior of electrons in different materials and environments. Models with quasi-periodicity, where something that locally looks periodic has behavior that may look chaotic at larger scales, are amenable to rigorous analysis.
I have problems with the proposed California math framework. A fundamental understanding in all the pre-calculus courses is hugely important for those who want to pursue STEM. American education needs fixing.

The Brexit Lie

Martin Fletcher

Rishi Sunak promises to govern with openness, integrity, and professionalism. He aims to put economic stability at the heart of his agenda. He should start by confronting the Big Lie that Brexit is good for the UK.
Sunak understands spreadsheets and statistics. He must know that while Covid‑19 and the Ukraine war have inflicted great economic damage on the UK, Brexit is also responsible for the profound economic crisis it now faces.
Leaving the EU has greatly complicated our trade with 450 million consumers just across the Channel. It has disrupted supply chains, deterred investment, caused labour shortages, created whole new layers of red tape, and more.
Read the business pages. Ask anyone in UK automotive, financial, hospitality, care, health, agricultural, or fishing industries. Consult the people who run small businesses, university chiefs, artists, and scientists.

The Liberal Faith

Matthew Syed

Faith in liberal democracy is wilting.
Pluralism in values is the hallmark of liberal democracy. Liberal democracies bring morality within the purview of reason rather than revealed truth. This is about moral autonomy.
Unlike dictators, liberal leaders relinquish power peacefully, encompass institutional constraints, and defend the right of free people to disparage what leaders say.
We live in a great nation. Unless we acknowledge the progress and sacrifices made by so many, we commit a grievous crime not merely against these pioneers, but ourselves.
Most young people in the UK would prefer a dictator to a democratic leader. Surveys in continental Europe and the US reveal similar trends.

Putin's Wars

The Sunday Times

Vladimir Putin has made veneration of the army a central pillar of Russian national identity.
Mark Galeotti explores the wars Russia has fought in since the end of the Soviet Union.
The first began in 1994 to prevent Chechnya seceding from Russia. It ended in humiliation for the Kremlin. The war was brutal and killed tens of thousands of civilians. Putin began a second bloody war against Chechnya in 1999.
The conflicts revealed shortcomings in the Russian military. Since then, reformers have supplemented conscripts by volunteers and updated equipment. But tanks and artillery remain the mainstay of the force, with logistics neglected.
Putin's brief war against Georgia in 2008 ended in victory but revealed the need for further reform. His seizure in 2014 of the Crimea from Ukraine went smoothly, but his later backing of Donbas separatists proved a hard slog.
Russian military involvement in 2015 in Syria in aid of its president, Bashar al‑Assad was a success. Putin propped up his ally at minimal cost while showcasing Russian arms.
The war against Ukraine has not gone to plan. Galeotti: "It is impossible to overstate just how devastating the impact has been. Arguably, 20 years of high-spending military reform was wasted in 20 days."
Putin wanted to turn Russia into a modern Sparta. But Russia still lags badly behind.

Neuromorphic Computing

Charles Q Choi

Neuromorphic microchip components spike above a certain rate of input signals. By only rarely firing spikes, they shuffle around less data than typical artificial neural networks.
Optical components can be used to connect neurons. Waveguides can connect each neuron with thousands of others. Superconducting nanowire devices can detect single photons.
Photonic neural computing needs optical cavities that can entrap light for long spans of time. Making such cavities and linking them with waveguides on an integrated microchip is tricky, so researchers made hybrid circuitry that converted the output signals from a detector to a 2 ps EM pulse forming a single fluxon in a SQUID network.
SQUIDs consist of one or more Josephson junctions. If the current through a junction exceeds a threshold, the SQUID emits fluxons. When triggered, a single-photon detector emits fluxons that collect as current in the SQUID loop. This stored current records how many times a neuron spiked.
Integrating these components creates a superconducting synapse that can spike at rates exceeding 10 MHz while consuming roughly 33 aJ per event. Human neurons have a maximum average spike rate of about 340 Hz and consume roughly 10 fJ per synaptic event.
The output of the devices can be varied to interface with a range of systems. The next step is to combine the synapses with on-chip photon sources to create integrated superconducting neurons.

UK: A Poor Country in Western Europe

Derek Thompson

UK living standards and wages have fallen behind those of Western Europe.
After WW2, the UK economy grew slower than those of much of continental Europe. By the 1970s, the Brits were debating why they were falling behind. In the 1980s, markets were deregulated to favor the financial sector. From the 1990s into the 2000s, the UK roared ahead, with London leading the way. Britain became the world's banker.
When the global financial crisis hit in 2008, it hit hard. The British government pursued a policy of austerity, fretting about debt rather than productivity or aggregate demand. The results were disastrous. Conservative pols blamed bureaucrats in Brussels, immigrants, and asylum seekers. A cohort of older voters demanded Brexit, and they got it.
In the past 30 years, the UK government economy chose finance over industry and austerity over investment. Voters chose a closed and poorer economy over an open and richer one. The predictable results are falling wages and low productivity growth.
The UK now has some of the worst productivity statistics of any major economy. What was once a powerful global empire voted to reduce global access to trade and talent. Since Brexit, immigration, exports, and foreign investment have all declined.
Outside London, the UK is one of the poorest countries in Western Europe.

A new period of conflict
John Gray

Britain is drifting into a state of chronic emergency. Starting this winter, living standards will fall for most of the population.
A bailout set the precedent for a tide of funny money after the crash of 2008. The market continued to devise opaque and risky products affecting trillions of dollars of assets. Any policy program that depends on economic growth will be stymied.

Carbon emissions from energy to peak in 2025
Jasper Jolly

Global carbon emissions from energy will peak in 2025 thanks to massively increased government spending on clean fuels, says the International Energy Agency. The IEA calls this a "historic turning point" in the transition away from fossil fuels.
The war in Ukraine has prompted a global energy crisis. IEA executive director Fatih Birol says this will accelerate the clean energy transition. Planned investments in green energy in response to the crisis will lead to demand for polluting fossil fuels peaking this decade.
Under the new plans, investment in low-carbon energy will rise to $2 trillion a year by 2030, an increase of more than 50% from today. But annual clean energy investment would have to reach $4 trillion by 2030 to reach net zero carbon emissions by 2050.

Quantum Physics and Observation

Markus Müller

Experiments indicate that physical entities do not have standalone existence but are products of observation. This is relevant to our understanding of reality.
Classical physics describes the objective and deterministic evolution of a unique material world. It keeps the observer out of the description. Quantum physics challenges this commitment: Bell's theorem challenges the assumption that measurements always reveal pre-existing properties of the world.
We may ask whether, and if so, how, the first-person perspective is an irreducible part of quantum physics, and what this says about the paradigm of materialism.

Being and consciousness
Graham Stew

Phenomenology is the study of the objects of consciousness as they appear to individual awareness. Phenomenologists seek to understand the inner world of our feelings, attitudes, sensations, and the meanings we attach to them.
Edmund Husserl is the founding figure of phenomenology. For Husserl, phenomenology was based on the intentionality of consciousness.
Phenomenology aims to understand our lived experience. Mental phenomena appear in awareness, but we usually claim ownership and responsibility for them.
Consciousness enables experience to create meaning and understanding. Mind comprises thoughts, sensations, and perceptions, all in consciousness. We see the mind as reflecting body and world, but attention brings form into existence out of infinite consciousness.
There is no scientific evidence for the existence of consciousness. Reductive materialism is the dominant paradigm in science.
Quantum theory suggests no object exists unless it is observed: Being and consciousness are one.

Bright Space Explosion

Jonathan O'Callaghan

On October 9, we saw the biggest cosmic explosion in history. It was a gamma-ray burst from a massive dying star as it collapsed into a black hole spurting powerful jets of energy.
This "brightest of all time" (BOAT) event oversaturated the Fermi Gamma-ray Space Telescope and may even have caused our ionosphere to swell in size for several hours.
The BOAT occurred about 23 Ym away and its jet was likely pointed toward us. In China, the LHAASO saw 5,000 high-energy photons from it, many times more than usual for GRBs.
An 18 TeV photon should have been lost on the way to us. Maybe an axion-like particle flew free until it came to our galaxy, where magnetic fields turned it into a photon.
If this photon is linked to the BOAT, it may be evidence of new physics.

Rejoin the single market and customs union
Jürgen Maier

The UK has a tradition of strong democracy and fact-based debate. Brexit changed this. Our government entered a game of lies and largely ignored the facts.
Years of lies, policy blunders, and incompetence have damaged the UK's global reputation. Rishi Sunak's government must focus on rebuilding it.
A good policy option is to rejoin the single market and customs union. It was the biggest lie of them all to imagine the UK could replace the economic upside of being part of the most advanced free-trade zone in the world.

Brexit ambitions clashed with real-world conditions: a pandemic, the rise of protectionism, tensions with China, and the war in Ukraine. Finally, the financial markets took back control.
German liberal MP Alexander Lambsdorff: "This is what happens when you cut your country off from your biggest and most important market. Brexit devours its children."

UK economy 'frankly doomed' by Brexit
Joanna Partridge

Billionaire businessman Guy Hands accuses Tories of putting the UK "on a path to be the sick man of Europe" and predicts a UK economy of higher taxes and interest rates and fewer social services.
The founder and chair of the private equity firm Terra Firma, a longtime Tory supporter, said the party needs to start "admitting some of the mistakes they have made over the last six years, which have frankly put this country on a path to be the sick man of Europe."
Hands said Liz Truss had tried to follow the "dream" of Brexit and a "low-tax, low-benefit economy" but: "Once you accept that you can't actually do that, the Brexit that was done is completely hopeless and will only drive Britain into a disastrous economic state."
Hands called for the next prime minister to renegotiate Brexit: "Without that the economy is frankly doomed."

Admit the lies of Brexit
Guy Hands

Believers in extreme Thatcherism were convinced it could be introduced once Brexit was complete and Britain had removed itself from the rules of the European single market.
The only way for the UK to compete on the world stage outside the EU is by becoming a European Singapore. Many Conservatives dream of such an economy. But the democratic path there is far from easy in a UK where only a tiny minority support the libertarian right.
All the Conservative party can do is to try to make the best of a bad job and get the books to balance to bring interest costs and inflation down before the next election.
Prior to Brexit, I predicted it would turn Britain into a country torn apart by high taxes, social unrest, strikes, low productivity, and poor social services. Sadly, this gloomy scenario is becoming reality. Brexit was about introducing a libertarian agenda to help the ultra‑rich.
The world has changed since 2016. Tories can now change direction and negotiate a revised Brexit. Done soon, this might put the UK on the path to recovery.

Sunak is a realist
Timothy Garton Ash

Prime minister Rishi Sunak can put an end to Brexitism. Over the past eight years, Britain has sunk from pragmatic Eurosceptism to the soft Brexit proposed by Theresa May, to the hard Brexit of Boris Johnson, and thence to the fantasy Brexit of Liz Truss.
Even before the 2016 vote, the UK had a chronic productivity problem, excessive reliance on the financial sector, and a major deficit in training and skills. The Brexit effect is now visible. On many indicators, the UK economy has done worse than any other in the G7.
Sunak is a realist, putting solid public finances and market credibility first. He knows that in challenging economic circumstances, you lower barriers to trading with your largest single market. He can kill the Truss bill to scrap all ex‑EU regulations next year.

Quantum Collapse

Philip Ball

Recent experiments have mobilized sensitive physics instruments to test the idea that quantum possibilities collapse into a single classical reality. The experiments find no evidence of the effects predicted by simple collapse models.
Physical collapse models aim to resolve a central dilemma of quantum theory. A wave function lets us predict the various possible outcomes of measurements made on an object and the probability of observing any one of them in an experiment.
If many measurements are made on objects prepared in the same state, the wave function correctly predicts the statistical distribution of outcomes. But we have no way of knowing what the outcome of any single measurement will be, only probabilities.
Giancarlo Ghirardi, Alberto Rimini, and Tullio Weber suggested a quantum system is constantly prodded to jump spontaneously into an observable state. A small system stays in superposition for a long time; bigger objects collapse into a classical state almost instantly. Continuous spontaneous localization (CSL) models are similar.
Roger Penrose and Lajos Diósi independently suggested gravity may cause the collapse: A quantum object in a superposition of locations feels a gravitational interaction between the locations, warping spacetime in many ways at once and forcing a collapse.
Collapse models make observable predictions. If a background perturbation provokes collapse, all particles interact with it, causing something like Brownian motion. Current collapse models suggest this motion is tiny.
If a particle is electrically charged, motion generates electromagnetic Bremsstrahlung. The particle should emit a faint stream of photons, predicted to be in the X‑ray range. Detectors in neutrino experiments can detect a CSL signature.
A team used the IGEX neutrino experiment to test the Diósi−Penrose model. The team saw no emission at a sensitivity level ruling out the simplest model and placed strong bounds on the parameters for various CSL models.

AR Reassuring to know. The models were conceptual hacks.


Higgs Boson Width

New Scientist

The LHC CMS collaboration has made the sharpest estimate yet of the "width" ΔE of the Higgs boson: ΔE ≈ 3.2 MeV. Quantum uncertainty implies that ΔE Δt ≥ ℏ/2. Hence the Higgs boson has a measured minimum average lifetime Δt of around 100 ys, a hundred yoctoseconds.

The legacy confronting her successor is bleak. Britain is humbled on the world stage and assailed by the financial markets. The economy is on the brink of recession.

The British Conservative party was credited for centuries with good sense, financial sobriety, and cautious pragmatism. Despised by progressive elites and allergic to ideology, the party was home for the boring middle.
The Conservatives now stand for chaos. It was foolish to suppose that Liz Truss could sack the most senior Treasury official, reinvent the laws of economic management, and defy the financial markets.
A chronic crisis of governance has reduced the UK to a global laughingstock. Conservatives chose Truss even though she was obviously not up to the job.
Like the Republicans in the United States, the Conservatives have become a party of monomaniacs, incompetents, and ideologues.

UK: Liz Truss Resigns as PM

The Guardian, 1335 BST

Liz Truss has resigned as prime minister after just 45 days in office. Her announcement follows an evaporation of her political authority that saw her crash the markets, lose two key ministers, and lose the confidence of almost all her own MPs.
Tory MP Ruth Edwards says her colleagues were "in tears" in the run-up to last night's fracking vote after being forced to choose between voting to lose the whip or voting against a manifesto commitment: "The trust between the parliamentary party and the prime minister no longer exists. You can only pull a stunt like that once. And you can't work as a team if the foot soldiers are treated with contempt by the general."
Last night, whips threatened Tory MPs with losing the whip if they voted with Labour on an anti-fracking motion. A minister wrongly said it was no longer a confidence vote, so many abstained. The chief whip resigned. After midnight, the media were told it was a confidence vote after all. The chief whip had un-resigned. MPs were left clueless.
At PMQ on Wednesday, Truss directly contradicted her new chancellor and said the "triple lock" on the state pension was safe. News broke that one of her most trusted and senior aides was suspended after a toxic briefing war. Truss then sacked her home secretary Suella Braverman following an argument over migration policy.

Truss has destroyed Brexitism
Jonathan Freedland

Liz Truss may well have killed off the vision of a low tax, low regulation society where the richest are freed to unleash their awesome talents and make themselves even richer.
Trussonomics slashed taxes on the top 1% to unleash the animal spirits of the free market. Financial markets recoiled from the plan. They could see no sign of how Truss hoped to pay for it.
Sterling tanked, the Bank of England warned that interest rates would have to climb steeply, and Britain became a distressed economy. Truss has discredited Brexitism.

The Tory experiment is dying
Polly Toynbee

Truss is gone. Her ideological hobgoblins turned on her. Two more years of the party that drove us over the Brexit cliff is unthinkable.
The UK is performing worse than any other country in Europe bar Greece and Cyprus. Post-financial crash, incomes in France grew by 34% and in Germany by 27%, while ours fell by 2%.
The UK economy was 90% of the size of Germany's in 2016, and now it has fallen to 70%. UK trade to the EU has fallen by 16%. Britain is now the most unequal country in Europe, bar Bulgaria.
The evil potion of the great Brexit lie that wildly misled so many is now wearing off. Labour should seize the moment. Poorer households are about to face a catastrophically bad year.
This has to stop. Two years more will break everything. What we need is an election.

Martial Law in Annexed Ukraine

Andrew Roth

Putin has announced the introduction of martial law in the four regions that his forces "annexed" from Ukraine. He hinted at a further escalation of the war: "Russia has repeatedly given a chance to the command of the satanists to come to their senses. But we were not heard or ignored. Now everything will be different, we will dictate the terms."

Trauma zone
John Gray

Adam Curtis used old tapes from the BBC offices in Moscow to create Russia 1985−1999: TraumaZone. Throughout the 7‑part series, he focuses on the faces and voices of ordinary Russians as they watch things collapse around them.
Mikhail Gorbachev plunged the Soviet Union into anarchy. His attempt at reform imploded and led to the cult of the free market. Western governments and companies promoted policies that had a catastrophic impact.
The result of applying this market fundamentalism was that pensions became worthless, savings evaporated as inflation raged, and life expectancy fell to third-world levels. Many Russians came close to destitution.
Vladimir Putin used the lawlessness of the Boris Yeltsin era to extend his authority. After he first became president in May 2000, he presided over a system of oligarchical rule and went on to create a totalitarian regime.
Failure of the Russian war in Ukraine could lead to his downfall. The Russian Federation could fracture and fragment. Liberals will cheer the end of Russian imperial power, but the dissolution will hardly be peaceful.

German exports and imports are soaring with everyone but the UK. Growth for the British economy is now expected to be just 0.8% a year for years to come. This is a disaster.

Fusion Dream


Nuclear fusion could become viable for electricity generation by 2035. Construction begins next year on the SPARC reactor, which should produce twice as much power as it consumes.
Fusion reactors use strong magnetic fields to contain extremely hot plasma. Generating the fields wastes a lot of energy. SPARC uses efficient new superconducting magnet technology.

Battling for survival
Sebastian Payne

UK prime minister Liz Truss is battling for her political survival as leading business figures and Conservative MPs pile pressure on her to resign. Downing Street is braced for further market turbulence as others call on Truss to quit. Her allies liken the "plotters" to Remainers.

The sad story of Brexit Britain
Stryker McGuire

From the 2016 referendum onward, Brexit increasingly gave the Tories a focus. But once Britain formally left the EU, discipline within the Conservative party began to unravel.
Liz Truss did not exactly restore confidence in Downing Street. Her new government shredded the Tory reputation for fiscal prudence and sound economic management. The reaction abroad to her "fiscal event" has been awful.
The damage today cannot be separated from what happened in the years leading up to Brexit. As a dual US−UK citizen in London since 1996, I see Brexit as part of a post-imperial hangover.
Virtually all the economic arguments in favour of Brexit looked specious at best and cynically misleading at worst. The post-Brexit trade deals the UK has negotiated are insignificant compared with the loss of EU trade.
The harm has been devastating. Ending the free movement of labour between Britain and the continent is hollowing out the workforce. Economic indicators are all going in the wrong direction.

A Tory Brexit cult
Matthew Syed

Brexit sits behind all that has unfolded in the UK. The true believers prophesied that the economy would grow ever faster when unshackled from the EU.
The language became ever more cultish as each Brexiteer prediction collided with reality and was found wanting. Backbenchers jeered and shouted Project Fear when MPs lamented how the economy had suffered.
The idea that the Tories can ditch Truss now and go on to win the next election stretches credibility. All the contenders now eyeing the top job are true believers. Brexit has become the sacred shibboleth of the party.
The Tory party was once a party of pragmatism, moderation, and realism. Please call an election, take a break, and find yourselves again.

Ukraine: Russian Kamikaze Drone Attacks


Ukraine has repeatedly asked its allies to supply it with more air defense systems and ammunition after Russia stepped up its use of Iranian-supplied kamikaze drones in strikes against Kyiv, Vinnytsia, Odesa, Zaporizhzhia, and other cities across Ukraine in recent weeks.
Kamikaze drones are loitering munitions that can wait for a time near a potential target and only strike once an enemy asset is identified. They are small, portable, easy to launch, and hard to detect.
The Ukrainian military and US intelligence say Russia is using Iranian-made attack drones. US officials say Russia bought these drones, which can carry PGMs and have a payload of about 50 kg. Ukraine says Russia has ordered 2,400 Shahed‑136 drones from Iran.
Ukrainian Defense Ministry: "In the past 13 hours, UAarmy shot down 37 Iranian Shahed‑136 drones and 3 cruise missiles launched by Russian terrorists"
Ukrainian president Volodymyr Zelensky: "All night and all morning, the enemy terrorizes the civilian population. Kamikaze drones and missiles are attacking all of Ukraine. A residential building was hit in Kyiv. The enemy can attack our cities, but it won't be able to break us. The occupiers will get only fair punishment and condemnation of future generations. And we will get victory."

UK: Jeremy Hunt Takes Control

The Sunday Times

Chancellor Jeremy Hunt is to delay the penny cut to income tax. He is now widely seen as the most powerful figure in government.
Truss is all but powerless. A cabinet minister: "Having dispatched her chancellor, who fell on his sword to defend her economic plan, I think it makes it very hard for her to survive."
Another: "I have not spoken to a single one of my cabinet colleagues who thinks this can go on much longer. If we don't change horses soon, we will be facing electoral annihilation."
Hunt is now the chief executive in government. He says the PM has in effect handed control of the public finances to him. He will deliver a fiscal statement on October 31.
He says the economic outlook is "far worse" than expected: "Spending will not rise by as much as people would like and all government departments are going to have to find more efficiencies than they were planning to."
Tory MPs are discussing how to evict Truss. Some aim to keep her going long enough to give Hunt time to settle in.

The unraveling
Michael Savage

Liz Truss is bracing herself for what comes next. A former cabinet minister: "She has trashed our reputation of economic competence .. She's got to go."
Last Wednesday at PMQ, Truss committed "absolutely" not to cut public spending and twice said she was "genuinely unclear" as if for a Labour attack ad.
That evening, Tory MPs asked her hostile questions. An MP asked whether infrastructure projects would now be funded or scrapped. There was an awkward pause.
On Thursday morning, Kwasi Kwarteng flew to Washington for an IMF meeting. That night, he caught the last plane back to London and said: "I'm not going anywhere."
By Friday morning, the markets had priced in changes to the mini-budget.

A Tiny British Publisher

Alex Marshall

Jacques Testard started his own publishing company in 2014 and called it Fitzcarraldo Editions.
Fitzcarraldo is now one of Britain's most talked-about publishing houses. When the French writer Annie Ernaux was awarded the 2022 Nobel literature prize last week, she became Fitzcarraldo's third author to gain the honor since the house's founding, after Olga Tokarczuk from Poland in 2019 and Svetlana Alexievich from Belarus in 2015.
The day after the Ernaux announcement, Testard ordered the reprinting of 65,000 copies of her books to keep pace with demand. Fitzcarraldo sold around 135,000 books across all its titles in 2021.
Much of the British publishing industry is baffled by Fitzcarraldo's success. But the fact that Testard reads fiction in French and Spanish, as well as in English, enables him to spot authors whom insular British editors miss.
Testard was a postgraduate student in history at Oxford until he went to work at The Sunday Times for a few months, then interned at publishers in France, Britain, and the United States. In New York in 2010, he was struck by the vibrant literary magazines and decided to start one in Britain. It has since become well known for publishing work by future literary heavyweights.
Fitzcarraldo began in 2014 with a vision. Half of its catalog would be books in translation. All would be at "the more radical end of contemporary writing" and mix genres such as memoir and fiction.
Testard receives tips from publishing editors across Europe and the United States, as well as from translators and authors he trusts. Most British and American publishers still think foreign fiction is too expensive or difficult.
Testard: "Risk-taking and having a commitment to authors over time really does work."

The Times

Three months ago, Jeremy Hunt stood for election as prime minister. Now he is chancellor.
Hunt is backed by the One Nation caucus of Tory MPs who have never backed Liz Truss. He is a millionaire and leant heavily on his business success when making his leadership pitch in 2019. The former president of Oxford University Conservative Association is also the son of an admiral and was head boy at Charterhouse. He became the longest serving health secretary before becoming foreign secretary in 2018.

Trade has declined on all measures, the currency had lost nearly a third of its value against the dollar even before Truss, investment has flatlined, and the current account deficit is over 8% of GDP. Neither the government nor the Bank of England can talk honestly about the weak fundamentals: Brexit is the source of the problem.

AR By far the best way to increase UK growth prospects is to rejoin the EU.

UK Political Turmoil

BBC News, 1539 BST

Prime minister Liz Truss delivered a short press conference aimed at restoring confidence in her government. She made a U‑turn on her government's decision to freeze corporation tax. The tax will now rise from 19% to 25% and raise £18 billion in taxes per year.
She was challenged over why she should remain in post when she had sacked Kwasi Kwarteng as chancellor for implementing her policies. Earlier this morning, 10 Downing Street said the pair had been working in "lockstep" together.
Truss said she was "absolutely determined" to see through her promise to deliver economic growth and added that her new chancellor Jeremy Hunt "shares her vision" and will deliver the medium-term fiscal plan at the end of the month.

Liz Truss should go
Daniel Finkelstein

There have been moments of crisis in the past century, but this is different. If Liz Truss remains as prime minister, it is hard to see her government reviving. The Conservative party will be doomed to defeat, and the country will have to live for two years with a stumbling government unable to connect with voters.

Labour shadow work and pensions secretary Jon Ashworth: "This is a government in utter meltdown .. Liz Truss has sacked her chancellor for carrying out the policies of Liz Truss − a set of policies that led to turmoil on the markets, a run on pension funds, and soaring mortgage rates for homeowners across the country. This is clearly a disastrous set of decisions from a disastrous budget .. we need a change of government."

'Hastened her demise"

US vs China

Thomas L Friedman

The US is locked in a struggle with China over the key technology of the information age. The alliance that designs and makes the smartest chips in the world will also have the smartest precision weapons and the smartest factories.
The Biden administration has issued new export regulations directed against China. The Chinese embassy in Washington says the US is going for sci-tech hegemony.
The new regulations bar any US expert from aiding China in chip manufacturing without approval. They also bar any company from supplying targeted Chinese entities with hardware or software whose supply chain contains US technology.
The most advanced semiconductors are made by global coalition of companies. The companies all trust premier chip manufacturer TSMC in Taiwan with their trade secrets. They all fear China will steal their intellectual property.
US secretary of commerce Gina Raimondo: "The US was in an untenable position. Today we are purchasing 100% of our advanced logic chips from abroad: 90% from TSMC in Taiwan and 10% from Samsung in Korea."
The new CHIPS Act aims to help make more of the advanced chips it needs in the US.
Raimondo: "China has a strategy of military−civil fusion .. We cannot ignore China's intentions."
The US and its allies aim to prevent China from learning to make the advanced chips.
Raimondo: "We don't want them in China's hands and be used for military purposes."
China says the ban will only spur it to stand on its own in science and technology. A Chinese analyst: "There is no possibility of reconciliation."

AR This is why the US backs Taiwan.


Green Energy

Jacob Rees-Mogg

I am not a green energy sceptic. I am in favour of intelligent net zero in which green energy will play the biggest role.
The UK has cut its greenhouse gas emissions by 40% since 1990 while growing the economy by over 70%. We can achieve net zero by 2050. But getting people on board requires us to show we can go green in a way that makes them better off, drives growth, and stimulates investment and innovation.
Our Contracts for Difference scheme has spurred £90 billion of investment in renewables and contributed to a 5× increase in electricity generation from renewable sources since 2012. In 2010, renewables accounted for 7% of UK electricity generation. Now they meet about 40% of UK needs.
Our growth plan will accelerate the delivery of infrastructure projects including windfarms and will boost the hydrogen industry. We will align onshore wind planning policy with other infrastructure to ease deployment and we will help householders with the upfront costs of solar installation.
We also need to focus on reinforcing the grid so that renewable electricity can reach homes and businesses. In exchange for supporting renewable energy companies, the energy prices bill requires them to charge consumers and taxpayers a fair price.
This will strengthen UK energy security and stop Putin holding us to ransom as we progress toward net zero.

A Holographic Cosmos

Dennis Overbye

Albert Einstein and Nathan Rosen predicted that black holes could form in pairs connected by wormholes. Einstein, Rosen, and Boris Podolsky showed that a pair of interacting quantum particles would be eternally entangled.
Stephen Hawking said black holes would over time leak away all the mass that fell into them in a random fizz of particles and radiation. Quantum theory says information is never lost, but information would be lost in black hole radiation.
A hologram is basically a 3D image made of light. Leonard Susskind speculated that a black hole may be a hologram, with the event horizon as the film, encoding the stuff inside. Gerardus 't Hooft had the same idea.
In general relativity, the information content of a 3D space is limited to the number of bits that fit on a surface surrounding it, measured in Planck pixels. Jacob Bekenstein defined the limit where cramming too many bits into a space would collapse it into a black hole.
Juan Maldacena fleshed out the cosmos-as-holograph idea with ideas from string theory to make a model of the universe as a hologram. In it, all the information about what happens inside a volume of space is encoded as quantum fields on the surface of its boundary.
The holographic universe is like a can of soup, where the information about the contents is outside on the label. The bulk and the boundary are complementary sides of the same thing. The fields on the boundary obey quantum conservation of information, so the gravitational fields in the bulk do too. The can of soup is a proof of principle that gravity and quantum mechanics are compatible.
Don Page proposed that information is conserved when a black hole evaporates. A black hole does not radiate randomly. The radiation starts out random, but as time goes on, ever more of the particles emitted are correlated with those that came out earlier, delivering the missing qubits.
Particles escaping the black hole are entangled with particles that leaked out earlier. But the escaping particles are already entangled with their mates that fell into the black hole, running afoul of quantum monogamy. This can only work if the particles inside the black hole are the same as those now outside, connected by wormholes.
Maldacena and Susskind proposed that entanglement and wormholes are two faces of the same phenomenon. As they put it: ER = EPR.
Calculations show that information leaking through wormholes matches the pattern Page predicted. Geoff Penington: "And so the final moral of the story is, if your theory of gravity includes wormholes, then you get information coming out."

A Russian Nuclear Attack?

Anusar Farooqui

Putin aims to signal resolve and persuade his adversaries to sue for peace. He has burnt his bridges. A dangerous nuclear crisis is emerging.
If Russia cannot avoid military humiliation in Ukraine, it will not survive as a great power. The US war aim is to weaken Russia, but a cornered Russia may well use nuclear weapons in Ukraine.
Any Russian nuclear use will transform the conflict. We should expect a worldwide panic, of the sort we have never seen before, and keeping the NATO alliance together will become difficult.
The psychological impact of a detonation alone would compel the Ukrainians to halt all military offensives immediately. The diplomatic effect would be to raise the global pressure on the warring parties to stop fighting and start negotiating.
The US will then find itself with only bad options. A US nuclear response is out of the question. If Putin goes further up the escalation ladder, a more muscular US response becomes likely.
Any US response in Ukraine risks strategic nuclear war between Russia and NATO. Yet no vital US interest is at stake. Negotiate.

Losing Crimea Could Finish Putin

Mark Galeotti

Vladimir Putin opened the bridge across the Kerch Strait in 2018 and drove the first truck over it. Saturday's attack on it was a direct blow to his authority. The truck bomb destroyed two concrete spans, dropping the roadway into the sea, and ignited fuel wagons on a passing train.
The attack poses a challenge to the Russian commanders of the Ukraine war. The bridge was a key supply line to Crimea and the Russian forces in Kherson. They must now rely on shipping and the land route through annexed Ukrainian oblasts. Moscow claims the rail link will shortly reopen, but the road section may take more than a month to be rebuilt.
Crimea is heavily defended territory that Russians claim as theirs. It was transferred to Ukraine only in 1954, when the two countries were still in the Soviet Union. Its loss might be the last straw that brings Putin down.

Kerch bridge blast will be felt in the Kremlin
Peter Beaumont

Putin, 2018: "In different historical epochs .. people dreamed of building this bridge .. And finally, thanks to your work and your talent, the miracle has happened."

UK Botches COP26 Presidency

The UK seems to be ending its presidency of the UN climate talks next month in disunity and disarray. Rows over climate policy are hampering its ability to hold together the fragile coalition of developed and developing countries it built at the COP26 climate summit last year.

Cosmic Magnetism

Stuart Clark

Gravity seems to explain the overall structure of the universe. But we invoke dark matter to help explain how galaxies and galactic clusters stick together.
Gravity acts over vast distances and pulls on all matter. Magnetism only affects electrically charged particles. But much of the stuff in the universe is plasma.
Hannes Alfvén suggested that the force exerted on plasma by magnetism ought to be big. Magnetic fields must play an important role in shaping the cosmos.
Only a very strong magnetic field could help shape galaxies. To create one, you need a plasma dynamo. Galaxy clusters have large empty volumes containing nothing but plasma. This plasma emits X‑rays and is 10 MK hot.
Cosmic dust grains in a magnetic field polarize any infrared light passing through them. In many spiral galaxies, the magnetic field follows the spiral pattern of the galaxy.
Turbulence in a plasma dynamo should hugely boost the strength of a magnetic field. Large laser laboratories can create a plasma hot enough to generate a turbulent dynamo.
The NIF in California can create a turbulent dynamo effect so strong that the magnetic field traps particles inside regions of the plasma to reduce the flow of heat by a factor of 100, creating hot and cold spots.
This ability of the magnetic fields to trap heat could explain the hot empty volumes in galaxy clusters. The magnetic field created by a turbulent dynamo could suppress the diffusion of heat for billions of years.
No one knows if magnetic fields in spiral galaxies are strong enough to replace dark matter.

AR A good way to get rid of some dark matter. If I understand correctly, torsional general relativity can get rid of the rest. As a mathematical exercise, how about quantizing a variant of Kaluza−Klein theory adding electromagnetism to teleparallel gravity in 5 dimensions?

Click Chemists Awarded Nobel Prize

New Scientist

The 2022 Nobel prize for chemistry has been jointly awarded to Carolyn Bertozzi, Morten Meldal, and Karl Barry Sharpless for their development of click chemistry and bio-orthogonal chemistry.
Nobel Committee member Olof Ramström: "Click chemistry is chemistry based on specific reactions that work very efficiently and are very reliable to generate robust yields of products. You can essentially snap together two molecule building blocks in a very efficient and predictive way .. Bio-orthogonal reactions have helped with exploring the roles of biomolecules in cells and organisms."

They developed click chemistry and bio-orthogonal chemistry

Carolyn Bertozzi of Stanford University, Morten Meldal of the University of Copenhagen, and Karl Barry Sharpless of Scripps Research developed click chemistry and bio-orthogonal chemistry. Click chemistry revolutionized the options available to us for creating intended molecules. Bio-orthogonal chemistry enabled us to monitor the chemical processes going on inside living cells without harming them.
The term "bio-orthogonal" denotes a chemical reaction that does not interfere with or interact with a living system. The ability to perform complex reactions in living systems without interfering with natural biological reactions enables us to study diseases inside cells or even inside complex organisms.
Nobel Committee for Chemistry chair Johan Aqvist: "It's all about snapping molecules together. [This has] led to a revolution in how chemists think about linking molecules together and how to do it in living cells."

AR Again, this is delightful news.


On Growth

Rowena Mason

In her Conservative party conference speech, Liz Truss set out a plan for "growth, growth, and growth" after an interruption by protesters waving a Greenpeace banner.
She said cutting taxes was "the right thing to do morally and economically" and explained her decision to withdraw her plan to abolish the top rate of income tax: "I get it and I have listened."
She said she would exert an "iron discipline" over public spending: "I believe in sound money and a lean state."
The pound fell against the US dollar after the speech.

AR She's deluded about economics.


On Truth

Hugo Rifkind

Gwyneth Paltrow: "My most lasting mistakes and the mess that comes with them have all stemmed from me not standing fully in my truth and speaking from it."
The idea that truth is all about where you're coming from is relativism. Nobody is more innately right than anybody else. Relativism is at the core of identity politics.
Cate Blanchett: "One of the phrases I just cannot say is 'my truth'. I mean, the truth is the truth, isn't it?"

AR Cate right, Gwyneth wrong.

Quantum Physicists Awarded Nobel Prize

New Scientist

The 2022 Nobel prize in physics has been jointly awarded to Alain Aspect, John Clauser, and Anton Zeilinger for experiments with entangled photons and their work in pioneering quantum information science.
Each of the winners carried out an experimental test of Bell's theorem. This involved measuring the correlation of properties of two entangled photons in an isolated system to see if it exceeds the Bell inequality.
John Clauser and Stuart Freedman were the first to test the Bell inequality. Their results violated it to a high level of statistical significance, implying that quantum mechanics has nonlocal effects. But their experiment left loopholes.
Alain Aspect at the University of Paris-Saclay and his team measured the Bell inequality again, to greater precision and with less doubt, by measuring the polarization of pairs of photons.
Anton Zeilinger at the University of Vienna and his team expanded their work to consider three or more particles entangled in a GHZ state. This is key for quantum computing, where GHZ states can be used as qubits.

Prize for ground-breaking experiments with entangled particles

Alain Aspect, John Clauser and Anton Zeilinger have won the 2022 Nobel Prize in Physics for experiments that proved the profoundly strange quantum nature of reality. Between them, they established the existence of quantum entanglement, where two widely separated particles appear to share information despite having no way of communicating.
Nobel Committee member Thors Hans Hansson: "The experiments performed by Clauser and Aspect .. provided tools for creating and manipulating and measuring states of particles that are entangled although they are far away."
Entanglement is now poised to power an emerging wave of quantum technologies. Anton Zeilinger has been at the forefront, developing techniques that use entanglement to achieve astounding feats of quantum networking, teleportation, and cryptography.
Nobel Committee member Eva Olsson: "Quantum information science is a vibrant and rapidly developing field .. Its predictions have opened doors to another world, and it has also shaken the very foundations of how we interpret measurements."
Albert Einstein, Boris Podolsky, and Nathan Rosen first described quantum entanglement in 1935. Einstein thought it would prove the death of quantum mechanics because it seemed to fly in the face of a central tenet of relativity. Instead, the EPR paper triggered a complete rethinking of reality.

AR I've been following this work closely for decades. Bell's theorem is fundamental. We live in a quangled omnium.


Truss, Kwarteng


UK Government Debt Crisis

BBC News

Many Tories are concerned about how they can justify boosting the take-home pay of the wealthiest while cutting the real incomes of the poorest.
As the government seeks ways to pay for promised tax cuts, plenty of Tory MPs seem willing to say benefits should not bear the burden of balancing the books.
Number 10 thinking is that help is already going to those who need it most. And plenty of Tory MPs are sceptical of a ballooning welfare budget.

Sterling is not out of trouble
The Guardian

UK PM Liz Truss will not rule out real-terms benefit cuts: "We are going to have to make decisions about how we bring down debt as a proportion of GDP .. we have to look at these issues in the round, we have to be fiscally responsible."
Argentex Group CEO Harry Adams: "We anticipate sterling to remain highly responsive to the notion of any further changes in government policy. There is no realistic scenario whereby sterling enjoys a straightforward recovery."

After the U-turn, the cuts
Gordon Brown

UK chancellor Kwasi Kwarteng has left £43G of his £45G in tax cuts intact. He is still doubling tax-free giveaways to those with share options, cutting £1G from tax on dividends, deregulating bankers' bonuses, giving away £4G for employees who become self-employed and for tax-free shopping by foreign tourists, handing out £19G of corporation tax cuts, and rejecting a windfall tax on excess oil and gas profits.
Public spending cuts will impede growth, ruin education, and undermine the NHS. By 2026, the cuts will add up to £42G ± £5G. Even venture capitalists need educated workers, functioning roads and railways, innovations incubated in universities, and a public health system. When the strong help the weak, we are all stronger.

AR Henceforth, £1G is a billion pounds sterling.




War in Ukraine

Chris Pleasance

Russia is losing the war, and Putin knows it. The despot is desperate. His army is in tatters, his battle plans are shot, he's burning through cash, and winter is looming. Meanwhile, Ukraine's army continues to advance.
Atlantic Council millennium fellow Alp Sevimlisoy says a Ukrainian victory would mean Putin being deposed, Russia breaking apart, and NATO facing off with China over the spoils: "Russia will have to come to terms with the fact that it is no longer a world power but a .. Black Sea state .. the domination of this region will be up to Turkey."

Is Putin in a bunker in Siberia?
Will Stewart

Putin will be 70 on Friday. The General SVR Telegram channel says he has warned his closest family that he may rapidly evacuate to a bunker a long way from Moscow, safe from attack.
Putin is said to have several bunkers in Siberia. One is on the Yamal peninsula and another in the Altai Mountains. His relatives and friends will go there too.
General SVR claims Putin is suffering from serious illnesses, but this cannot be verified.

AR Russia is certainly due for a fall.

Geneticist Awarded Nobel Prize

New Scientist

Svante Pääbo has been awarded the 1922 Nobel prize in physiology or medicine for his work on human evolution and the genomes of our extinct human relatives.
In 1990, Pääbo − who founded the Max Planck Institute for Evolutionary Anthropology in Leipzig − pioneered methods to sequence ancient DNA by starting with mitochondrial DNA.
Nobel committee chair Anna Wedell: "Humanity has always been intrigued by its origins .. Pääbo finally achieved the impossible, sequencing and assembly of the Neanderthal genome .. and discovered a completely new hominin entirely by analysing and comparing genome sequences."
Pääbo found that modern humans diverged from Neanderthals roughly 800 ky ago. Some 2% of the genome in people of European or Asian descent originates from Neanderthals.
Pääbo also discovered a new type of hominin, the Denisovans. People in Melanesia and parts of SE Asia have up to 6% Denisovan DNA.

Early human genomes decoded

Svante Pääbo has won the prize for his pioneering work on extinct humans and human ancestors. He fathered paleogenomics.
Homo sapiens shares significant DNA sequences with the Neanderthals and other earlier hominins. Pääbo and his team developed new techniques to extract, duplicate, and read the old DNA and reconstruct the original genome. They sequenced the Neanderthal genome and discovered the Denisovans.
Through new sequencing technologies and advanced computational analysis, Pääbo and his team sequenced DNA from 40 ky old bones. In 2010, they published the first full sequence of the Neanderthal genome in 2010.
Neanderthals and Denisovans split an estimated 380 ky to 470 ky ago. Modern humans split from the two other species some 550 ky to 760 ky ago. The most recent common ancestor of them all lived around 1 My ago.
Evidence of human interbreeding with Neanderthals and Denisovans appears as genetic variants in some people today.

AR Fascinating work.

BBC 1, Sunday: Laura Kuenssberg interviews Liz Truss

UK PM: No Retreat

Laura Kuenssberg

From our long conversation this morning:
  Liz Truss has no intention of changing her plans for the economy
  Her decisions may well involve spending cuts in the next few years
  She didn't consult her Cabinet over scrapping the 45p top tax rate
  She knows the last week has not been an unalloyed success
She faces the Conservative party conference in Birmingham this week.

Mistakes were made
Financial Times

Liz Truss admits mistakes were made in the controversial mini-budget that sparked market turmoil last week. She says she will not retreat on her plan to deliver £45 billion of unfunded tax cuts but admits: "We should have laid the ground better and I have learned from that."

Chancellor revealed plans to financiers
The Sunday Times

Hours after delivering his mini-budget to the Commons, UK chancellor Kwasi Kwarteng attended a private champagne reception at the Chelsea home of financier and Conservative Party donor Andrew Law.
The guests, who included stockbrokers, bankers, financiers, and investors, congratulated Kwarteng on his proposals. After the reception, hedge fund bosses who stood to profit from a falling pound told associates Kwarteng was a useful idiot.
Enemies of the chancellor say his contacts have influenced his decisions in office. Over the summer, Kwarteng privately dined with his former boss Crispin Odey, a hedge fund investor and sponsor of Brexit.

UK reputation is undone
Matthew Syed

The reputation of the UK is undergoing a historic fall. The British state has lost its moral and institutional bearings. Some will doubtless point at Brexit as the original sin.
Liz Truss has unshackled the UK government from the institutional guardrails of the Office for Budget Responsibility, proposed unfunded tax cuts on the rich during a cost-of-living crisis, and threatened to unleash benefit cuts on the poor.
For this government, compromise and pragmatism are dirty words. Our cultural inheritance is being napalmed by a leader out of control. We need a general election.

AR I'm not making this up.

Putin's Downfall

Christian Esch

President Vladimir Putin, 69, won't back down. He has expanded his "special military operation" in Ukraine into a war and hinted at using nuclear weapons. There is no turning back for him.
Putin is destroying his own legacy. His military contractor is recruiting murderers and sex offenders and sending them to Ukraine. A TV host says those who mismanaged the mobilization should be shot. Hundreds of thousands of Russian men are fleeing abroad.
Putin held mock referendums in four regions of Ukraine. Now he has annexed them, he sees his attacks on Ukraine as a defense of his own borders. Crimea is just one of the Ukrainian regions he says are Russian.
Russia, he says, will respond to a threat to its territorial integrity with all the means at its disposal. A Kremlin propagandist says there are only two possibilities: quick victory or nuclear war.
Putin can destroy Ukrainian cities and infrastructure far from the front lines. He can try to flood the battlefields with untrained soldiers. He can force Belarus to help him. But he cannot admit defeat.
His big mistake is messing not just with the West but with an opponent for whom the fight is existential. Ukrainians have shown what price they are willing to pay. They won't back down.
