AI Extinction Risk

The New York Times

Center for AI Safety open letter: "Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks, such as pandemics and nuclear war."
Signatories include OpenAI chief executive Sam Altman, Google DeepMind chief executive Demis Hassabis,and Anthropic chief executive Dario Amodei. Turing Award winners Geoffrey Hinton and Yoshua Bengio, as well as other prominent researchers in the field, also signed the statement.
Recent advances in large language models raise fears that AI could soon be used at scale to spread misinformation and propaganda or to eliminate millions of white-collar jobs.
AI has already surpassed human-level performance in some areas and will soon surpass it in others. Millions of people turn to chatbots for entertainment, companionship, and increased productivity.

Simulating Universes

Renate Loll

Computers can probe possible quantum structures of spacetime.
Jan Ambjørn and I put causal structure into spacetime in our theory of causal dynamical triangulations. CDT is a framework for calculating which geometry should arise from quantum effects. We hack a theory into a fixed number of little pieces so that a computer can handle it.
We glued triangles together to make a curved canvas. By adding or removing different numbers of triangles at each point, you can capture any spacetime curvature. Then we let the shapes interact according to both classical and quantum rules and make the lattice finer and finer until the triangles melt away into shapeless points.
We used a path integral to infuse Einstein gravity with a quantum essence, where the universe is a superposition of all possible spacetimes. We worked up to 4D and found the flock grows as if it were a 3D universe with one time direction. Einstein gravity, the path integral, and causality arranged the building blocks in an expansive 4D universe.
We studied the simulated diffusion of an ink drop in our 4D universe. It spread out as if it were in a roughly 2D space for a few instants before it spread normally, as if the quantum structure of space­time over very short distances is fractal-like. If you zoom out, everything looks 4D, but the micro­structure has a quantum signature.
Numerical methods help us check quantum gravity models.

AR Excellent progress: I've been intrigued and delighted by this approach for years.

UK Voters Warming Toward EU

Toby Helm

A clear majority of British voters favours building closer relations with the EU.
New polling shows a reversal in the tide of public opinion since Brexit. Even in constituencies with the highest votes to leave the EU in 2016, more than twice as many voters now believe the best route forward is to forge closer ties with Brussels.
The poll found that three times as many adults now believe Brexit has created more problems than it has solved, compared with those who believe it has solved more than it has created. Overall, 53% of voters want the government to seek a closer relationship with the EU than it now has, against 14% who want the UK to become more distant.
Official figures show that net migration to the UK rose to a new high of more than 606,000 in 2022, despite government claims that Brexit would enable the UK "take back control" of its borders. Yet most voters say the UK should issue more visas to allow foreign workers to come to the UK.
The UK economy and its trade have been damaged as a result of Brexit.

Identity and Morality

Stephen Mulhall

Parfit: A Philosopher and His Mission to Save Morality by David Edmonds
For David Edmonds, Derek Parfit, who died in 2017, was one of the greatest moral thinkers of the past century.
Parfit spent most of his intellectual life at All Souls College in Oxford. He may have met the diagnostic criteria for an autism spectrum disorder. He aimed to make ever more scrupulous discriminations between ethical stances and their variants, to find foundational premises, and to construct a unified theoretical account.
Parfit published just two books in his lifetime. Reasons and Persons (1984) secured his senior research fellowship. On What Matters appeared after more than thirty years of intense labour and was around 1900 pages long.
For Parfit, a person is constituted by relations of psychological connectedness and continuity related to a particular brain. These psychological relations are created by phenomena such as memories and intentions and are plainly a matter of degree.
He accepted a reductionist framework that makes our relation to our future selves less substantial than we take it to be and renders the distinction between ourselves and others less absolute.
For Parfit, each of us is the product of a union between a particular sperm and a egg. A child conceived by our parents at any other time would have involved a different sperm and egg, so would have been a different person. This observation casts doubt on whether we harm future people by our choices in the present.
Parfit set off on a long and fruitless search for a new theory. He aimed to show that three main approaches to moral philosophy converge on a single perspective and that moral values and judgments are objective. He swam against the tide.

AR I find Parfit's views plausible but I've not studied them closely.

Truth Is Sacred

Tom Hanks

The .. truth .. is .. that of course we are all created equally yet differently and of course we are all in this together. We are all but human ..
The truth, to some, is no longer empirical. It's no longer based on data nor common sense nor even common decency ..
Telling the truth is no longer the benchmark for public service. It's no longer the salve to our fears or the guide to our actions. Truth is now considered malleable, by opinion, by zero-sum end games ..
Every day, every year, and for every graduating class, there is a choice to be made ..
If you live in the United States of America, the responsibility is yours. Ours. The effort is optional, but the truth is sacred, unalterable, chiseled into the stone of the foundation of our republic.

Birth of the Self

Brooke Allen

Andrea Wulf: "When did we begin to be as selfish as we are today? At what point did we expect to have the right to determine our own lives? When did we think it was our right to take what we wanted? .. When did we first ask the question, how can I be free?"
Wulf locates the moment in the small German university town of Jena, in the years between the onset of the French Revolution and the town's devastation by Napoleon's armies in 1806.
Wulf was fascinated by the "Jena Set" with whom Alexander von Humboldt socialized and worked during the 1790s. Between 1789, when Friedrich Schiller arrived in Jena to lecture on history and aesthetics at the university, and 1807, when Georg Wilhelm Friedrich Hegel finally left the nearly ruined town, the group of thinkers and authors lived there included Johann Wolfgang von Goethe, Johann Gottlieb Fichte, the Humboldt brothers, the Schlegel brothers, the Wilhelm brothers, Friedrich Hölderlin, Novalis, Ludwig Tieck, Friedrich Schelling, and Caroline Michaelis Böhmer.
All these people worked side by side, until by the turn of the nineteenth century, they had mostly fallen out with one another. Their proximity during those years had a great deal to do with the birth of Romanticism.

The EU Has Become Stronger

Stefaan De Rynck

In June 2016, the UK vote to leave was for the EU. The agreement reached in December 2020 created a new equilibrium of rights and obligations in the EU−UK relationship.

Arresting Putin

Gordon Brown

A new grassroots campaign calls for Russian president Vladimir Putin to be tried for war crimes.
The next BRICS summit will be held in Johannesburg in August. Putin's recent indictment by the ICC means he can now be arrested there. A government commission in South Africa says his presence would violate not only international law but also South African law.
Earlier this year, ICC investigators set out evidence confirming that Russia had abducted thousands of Ukrainian children. Rape, torture, mutilation, and the indiscriminate bombing of innocent civilians are among the further crimes now under investigation.
The charge of aggression is provable by reference to the clear evidence of the decisions made to occupy Ukrainian territory. While the ICC does not have the power to charge Putin with this crime, a special tribunal could do so.
A tribunal could be mandated by a majority vote of the 193 members of the UNGA.

ANNs Learn Language Like Humans

Steve Nadis

Natural and artificial neural networks seem to learn languages in similar ways.
Researchers compared the brain waves of humans listening to a simple sound to the signal produced by a neural network analyzing the same sound. The results were uncannily alike.
To establish a baseline, the researchers played the syllable "bah" repeatedly to English speakers and Spanish speakers while recording fluctuations in the average electrical activity in their brainstems.
The researchers also fed the same "bah" sounds to two ANNs, one trained on English sounds, the other on Spanish. The processing activity of the ANN in the layer where sounds are first analyzed closely matched the human brain waves.
The ANN was composed of a discriminator and a generator. The generator creates a sample, the discriminator determines how close it is to a training sample and offers feedback, the generator tries again, and so on until the ANN delivers the desired output.
The discriminator was trained on the sounds. The generator started out by making random sounds, but after some 40,000 rounds of interactions with the discriminator, the generator got better.
Once the discriminator was trained, the researchers played it the "bah" sounds and measured fluctuations in the average activity levels of the discriminator's neurons.
The human and machine activity levels were similar.

AR This suggests the "Turing test" will be rather easy to pass.

A Multipolar World

Michael Lind

Liberal internationalism has failed. Its promise was that struggles among countries could be replaced by collaboration to promote mutual security, mutual prosperity, and common values.
Liberal internationalists have been committed to a world of national self-determination by many sovereign states. They have sought to reconcile national independence with global harmony by replacing competition among states with global governance.
They hoped that conflicts of values among countries would disappear. They distinguished liberal from illiberal states and democracies from autocracies and assumed that the conversion to Western liberalism was inevitable.
In the emerging multipolar world, states will look after their own security, alone or with military allies. In formerly liberal democracies, real power has drained from legislatures to increasingly powerful executives, judiciaries, transnational agencies, and corporations.
Military and economic competition, together with conflicts of religious and secular values, cannot be eliminated. But interstate conflicts can be moderated and prevented from escalating. Conflicts among values can be managed.
The tragedy of great power politics is a permanent feature of a world without a world government.

Hylomorphism

Robert B Brandom

"Hegel's .. nonpsychological conception of the conceptual .. is .. an understanding of conceptual content in terms of modally robust relations of exclusion and inclusion .. The result is a hylomorphic conception of the conceptual. Conceptual contents .. show up in two different forms .. The subjective form articulates what things are or can be for consciousness, and the objective form articulates what things are or can be in themselves .. They are related as the two poles of the intentional nexus: what can be known and the attempted knowing of it, noumena and phenomena."

and a lot of medieval pageantry in an overwhelmingly Christian service.

all the armed services and many Commonwealth countries.

Slava Ukraini

Bernard-Henri Lévy

Putin starts from the hypothesis that Ukraine does not exist, that Ukrainian culture does not exist. If I dare give a certain logic to this crazy war, it is in the logic of the denial of the Ukrainian identity. This barbarity matches with this logic of the denial of the very existence of Ukraine.
I'm not sure the west understands what is at stake. Without the resistance of the Ukrainians, maybe the Baltic states would be invaded at this moment, the Chinese would have started their operation on Taiwan, and so on.
The Ukrainians often thank us for our help. We should thank them. Every week, every day, has a real cost. The more the victory of Ukraine is delayed, the more the disaster grows.

The Kremlin must end this war
Lawrence Freedman

Putin originally aimed to subjugate all of Ukraine. He now says peace can be discussed as soon as Ukraine acknowledges that the four oblasts of Donetsk, Luhansk, Kherson, and Zaporizhzhia are a permanent part of Russia.
The recent Russian offensive was intended to take Luhansk and Donetsk. But after months of effort, the Russians have suffered huge casualties while making few advances. Bakhmut has become the symbol of this struggle.
Russia has also failed in its systematic campaign to take out Ukraine's critical infrastructure. A drone attack against the Kremlin this week led the Russian leadership into paroxysms of fury. Perhaps it was a Ukrainian provocation.
Absorbing the Russian offensive has not been easy for Ukrainians. They have asked whether it would have made more sense to withdraw. But these attritional battles have prevented a Russian advance and inflicted heavy losses.
Ukrainians are now preparing an offensive. Fresh brigades are almost ready to move. But the enemy has prepared elaborate defences to block them. There are concerns about gaps in Ukrainian air defences and insufficient ammunition.
A Ukrainian offensive offers a chance of a breakthrough. But if it fails, Ukraine will face a continuing stalemate and another harsh winter of fighting and energy shortages. International calls for a cease­fire will grow louder.
However much land is taken, the main objective must be to convince the Russian elite of the futility of this war and the fragility of its occupation. The Kremlin must end it.

Assembling Life

Philip Ball

Assembly theory offers a general way to identify molecules made by living systems.
The theory aims to explain why apparently unlikely things exist by appeal to a process that imbues objects with histories and memories of what came before them. It provides a consistent and mathematically precise account of the apparent historical contingency of how things get made.
Complex objects arise from combining many simpler objects. We can measure an object's complexity by calculating the minimum number of steps needed to make the object from its ingredients. This is its assembly index.
Very complex things can arise from random assembly processes, but the chances of getting two identical molecules in this way are vanishingly small. Finding many identical complex molecules is improbable unless some orchestrated process is at work.
If a molecule is abundant enough to be detectable, its assembly index can indicate whether it was produced by an organized process. We can calculate the minimum number of steps needed to make different molecular structures.
Large molecules with high indexes fracture into more complex mixtures of fragments than those with low indexes. Complex mixtures of molecules made by living systems typically have higher average indexes than minerals or simple organics.
The theory helps us root our understanding of Darwinian evolution in physics.

Time is fundamental
Sara Imari Walker

Darwinian evolution is the only physical process we know that can generate the succession of novel objects we associate with life. Such objects take time to evolve. They require a memory of the past to construct things in the present. Everything living requires a memory and information flow.
As objects become more complex, the number of unique parts that make them up increases, and so does the need for local memory to store how to assemble an object from its unique parts. We call the lowest number of steps to build an object from its elementary parts its assembly index.
Assembly theory treats this shortest path as an intrinsic property of the object. An assembly index can be measured for molecules using several different measuring techniques. We have shown in the lab how molecules with an assembly index above 15 steps are only found in living samples.
With this theory, we can test our hypothesis that life is the only physics that generates complex objects. We can do so by identifying those objects that are so complex the only physical mechanism to form them is evolution.

AR Assembly depth probes deep time − intriguing.

Brexit isn't working
Mike Galsworthy

Repeated polling shows not just that people think Brexit was the wrong decision, is not working on immigration and travel, and is not working for business, but also that most people would vote to rejoin if they could.
We in the European Movement want to rejoin the EU. We are not just a Westminster outfit. In every location of the country, a local group is getting into local press, doing local events, meeting up with local groups, and building from the grassroots up.
The Conservative party, if it loses the next general election, will think about how to win power again. If Brexit is unpopular at that stage, they will need to think about how they approach Europe.
I'm happy with the Labour position. If Labour were pro-Europe now, every time they got on interviews people would drag it back to the Brexit vote and back to 2019. As it is, they twist and turn awkwardly. They give us space to set things out on our terms.
The Liberal Democrats care about winning as many seats as they can, about Europe, and about proportional representation. All those go together nicely.

AI Is Scary

Geoffrey Hinton

Crows can solve puzzles. They do it by changing the strengths of connections between neurons in their brain. It must be possible to learn complicated things by changing the strengths of connections in an artificial neural network.
Our brains have 100 trillion connections. Large language models have a trillion at most. Yet GPT‑4 knows hundreds of times more than any one person does. So maybe it's got a better learning algorithm than we have.
These large language models can confabulate. These models are doing something just like people. We don't expect them to blather the way people do. When a computer does that, we think it made a mistake.
If you or I learn something and want to transfer that knowledge to someone else, we can't just send them a copy. But I can have 10,000 neural networks, each having their own experiences, and any of them can share what they learn instantly. It's a new and better form of intelligence.

Dangers Posed by AI

Cade Metz

A neural network is a mathematical system that learns skills by analyzing data. Neural networks that learn from huge amounts of digital text are called large language models, LLMs:
•  OpenAI's ChatGPT can respond to complex questions, write poetry, generate code, plan vacations, translate languages, and even respond to images.
•  Microsoft's Bing can hold open-ended text conversations on virtually any topic, but it occasionally gives inaccurate, misleading and weird responses.
•  Google's Bard was designed to draft emails and poems, but it can generate ideas, write blog posts, and answer questions with facts or opinions.
By pinpointing patterns in that text, LLMs learn to generate text on their own, including blog posts, poems and computer programs. They can even carry on a conversation.
This technology can help computer programmers, writers and other workers generate ideas and do things more quickly. But experts warn that LLMs can learn unwanted and unexpected behaviors.
They can generate untruthful, biased, and otherwise toxic information. Systems like GPT‑4 get facts wrong and make up information, a phenomenon called hallucination.

Short-Term Risk: Disinformation
These systems deliver information with what seems like complete confidence, so it can be a struggle to separate truth from fiction when using them. People may rely on these systems for medical advice, emotional support, and the raw information they use to make decisions. People could misuse these systems to spread disinformation. Because they can converse in humanlike ways, they can be surprisingly persuasive.

Medium-Term Risk: Job Loss
Experts say the new AI could be job killers. Right now, technologies like GPT‑4 tend to complement human workers. They cannot yet duplicate the work of lawyers, accountants, or doctors, but they could replace paralegals, personal assistants, and translators.
Allen Institute for AI founding chief executive Oren Etzioni: "There is an indication that rote jobs will go away."

Long-Term Risk: Loss of Control
Some say AI could slip outside our control or destroy humanity. But that may be wildly overblown.
Theoretical physicist Anthony Aguirre: "If you look at a straightforward extrapolation of where we are now to three years from now, things are pretty weird. If you take a less probable scenario − where things really take off, where there is no real governance, where these systems turn out to be more powerful than we thought they would be − then things get really, really crazy."

AR The systems need good regulation.

Rebuilding Britain

Andrew Marr

Britain can recuperate. The UK is weak but remains whole after challenges from Scotland and NI. It is in political and economic convalescence.
Most of the increase in the UK population this century came from migration. The increase in wealth is unevenly spread. From a food perspective, a sustainable UK population should be 20 million or below, so there are around 50 million "too many" of us.
Our economic debility comes first from a lack of growth. One agenda suggests we should measure development not by material economic advance alone but by indices of human happiness. Still, without economic growth, life for too many people becomes grimmer and harder.
Our children expect a considerably worse standard of living than we enjoyed. There is a huge rebuilding and recovery job to be done. This includes the judicial and criminal system, the health service, education, a green energy revolution, and restoring freshwater ecosystems.
This job of rebuilding almost certainly requires a new government, probably a majority Labour one. But the backlash will be ferocious. We can already see the first flickers of extremism in NatCon UK. We must choose the path to decent normality.

National Conservatism
John Harris

National Conservatism has branches in the US, UK, Hungary, and the Netherlands. It is an offshoot of the Edmund Burke Foundation, a US think tank founded in 2019. Its statement of values develops the populism associated with Donald Trump and Boris Johnson into something moralistic.
NatCon seeks a world of independent nations, societies centred on the traditional family, and a big official role for Christianity. It has a defensive view of what constitutes national communities and how to sustain them. Its advocates argue that immigration is a source of weakness and instability, citing "values" that conceal a tangle of ideas about culture and nationhood with sinister echoes.
The NatCon UK mix of authoritarianism, nostalgia, and hostility to immigration recalls and updates the spirit of Enoch Powell. Home Office minister Robert Jenrick: "The nation has a right to preserve itself .. uncontrolled migration threatens to cannibalise the compassion of the British public."
In his notorious "rivers of blood" speech, Powell had said immigration from the Commonwealth suggested "a nation busily engaged in heaping up its own funeral pyre". Thirteen years of Conservative government and the failures of Brexit have brought us down to this.

AR There is hope − in a decade or two.

Topological Solitons

New Scientist

String theory posits topological solitons, a region where spacetime warps and forms a hole that light can fall into, like it falls into a black hole. But topological solitons would show light swirling about their center, whereas black holes trap all the light that enters them.
Modeling a topological soliton gives images of how it would look through an instrument like EHT. The images show light falling into the hole bouncing inside its edges, so the center is not black.
Topological solitons could help solve the black hole information paradox. If signals previously interpreted as from a black hole come from a topological soliton, the paradox becomes irrelevant. Any observations showing central structure could indicate topological solitons.

AR The paradox is solved already, thanks.

a gospel reading by Canon Brian Mountford, a prayer, and a delightful choral solo rendition of Ave Maria
to music by Schubert. Then came tributes, followed by another choral solo, this one of Laudate Dominum
to music by Mozart, more tributes, an anthem, more prayers, a hymn, and a blessing. The finale was a

The Coronation of Charles and Camilla

The Sunday Times

King Charles and Queen Camilla will be crowned in a two-hour service in Westminster Abbey next Saturday. The ceremony will be conducted by Archbishop of Canterbury Justin Welby.
The Stone of Destiny will sit beside the Coronation Chair. Prince William will kneel before his father to recite the Homage of Royal Blood: "I, William, Prince of Wales, pledge my loyalty to you, and faith and truth I will bear unto you as your liegeman of life and limb. So help me God."
Once Charles is crowned, the archbishop will invite the congregation and millions of TV viewers around the UK and the Commonwealth to join him in reciting the pledge of allegiance, also known as the Homage of the People: "I swear that I will pay true allegiance to Your Majesty, and to your heirs and successors according to law. So help me God."
The liturgy has the theme of "called to serve" and includes new features:
•  Charles will recite aloud a King's Prayer written for the occasion.
•  Female clergy will also participate in the ceremony.
•  The service will include languages spoken natively in the UK other than English.
•  UK prime minister Rishi Sunak will read from the Bible.
•  Faith leaders from Jewish, Hindu, Sikh, Muslim, and Buddhist communities will recite a
    greeting to the King in unison.

The British Brexit Blunder

William Keegan

Thanks to Brexit, there is supply-chain chaos all over Britain. The Conservatives are pretending they can make a success of a manifest disaster, yet the Labour opposition refuses to challenge it on the biggest self-inflicted crisis in recent British history.
The economy is damaged by the consequences of Brexit at almost every turn. A rise in import prices is a consequence of Brexit and explains why UK inflation rate is so high. Yet the two major parties refuse to recognise the scale of the disaster.
A recent poll shows 59% of respondents say Brexit has made Britain worse off and 55% say Brexit was a mistake. Analysis shows the Labour lead would be higher if Labour said Brexit was a mistake. Labour could win back all its "red wall" seats.

Ukraine's Big Offensive

Mark Galeotti

Ukraine's spring offensive against Russian occupiers is due soon. Defense minister Oleksii Reznikov: "As soon as there is God's will, the weather, and a decision by commanders, we will do it."
US intelligence assessments say Ukraine is unlikely to make more than "modest territorial gains" from the entrenched Russian forces.
So far the Ukrainian military has demonstrated not just skill and determination but also imagination. They have outfought and out-thought their enemies on a tactical level. They have often also caught the Russians by surprise at an operational and strategic level.
NATO secretary general Jens Stoltenberg says 98% of promised western weaponry has been delivered. The Ukrainians are deploying the 230 western tanks and 1,550 AFVs, but they still lack proper air defenses for any big offensive operation. They will also need more shells, bullets, and missiles.
To maintain western support, President Zelensky must show what US officials call a return on investment. Domestic hawks prevent him pushing negotiations, so Kyiv will have to attack.
Moscow knows this. Satellite photos show a growing array of trenches and fortifications along likely lines of Ukrainian attack. But Russia too is running short of PGMs and ammunition. The more aggressive its operations, the more losses it takes.
The Kremlin is seeking to avoid direct provocation of NATO. Russian foreign minister Sergey Lavrov says NATO is trying "to break Russia apart" but is actually making it stronger. Yet Moscow must now watch Ankara and Tehran acting in regions where it once held sway.
China is gaining more traction the longer the war continues. Beijing is still not supplying weapons, ammunition, or even the kind of unconditional political support Putin wanted.

AR So far, stalemate.

Can China Broker Peace in Ukraine?

Rajan Menon, Daniel R DePetris

Xi Jinping's phone call with Volodymyr Zelensky was no surprise. Yet Xi has no illusions about the difficulty of serving as mediator in the war between Ukraine and Russia.
The Chinese peace proposal advocates negotiations and a comprehensive ceasefire. It says nothing about the territorial terms of a settlement and stresses the need for both sides to show restraint and respect the "sovereignty, independence and territorial integrity of all countries, regardless of whether they were weak or strong, rich or poor".
Xi must know that Russia cannot achieve its territorial objectives by winning the war militarily. Xi also wants to protect Chinese economic interests in Ukraine over the long term. Yet Xi will understand that there will be more war in the short term.
The Ukrainian military is preparing a major counteroffensive. The NATO allies continue to arm Kyiv for a successful campaign. The Russian military has been solidifying its defensive positions. Neither Ukraine nor Russia will rush to the bargaining table any time soon.

AR Let's see Xi push Putin.

King Charles

Clive Irving

King Charles III is limited in his freedom to act. A few days after he took the throne, Liz Truss cancelled his planned trip to the world climate summit in Egypt. Charles held a Buckingham Palace reception for delegates instead.
The King was next lured into a political stunt. The government gave the name "Windsor" to the deal on Northern Ireland's Brexit mess. Although the Windsor Framework was signed at a chain hotel and announced in a guildhall, Ursula von der Leyen took tea with the King at Windsor Castle.
The royal culture sustains a power structure with a strong resistance to change. The royal household is a sprawling bureaucracy with many layers and plenty of opportunity for those who run it to defend their perquisites.
King Charles has become steadily richer. In the last decade before he became King, the value of his Duchy of Cornwall portfolio leapt by about a half. The Duchy pays no corporation tax because it is not considered a company.
Charles does not pay capital gains tax. His personal wealth is a part of the sovereign wealth fund of the House of Windsor. The Crown Estate property portfolio is worth over £16 billion and includes the territorial waters around the UK. In January, the Crown Estate licensed six new offshore wind farms in a deal worth £1 billion a year.
Charles has never welcomed outside scrutiny of royal wealth. His version of monarchy looks increasingly like plutocracy.

Sea Power

Roger Boyes

The future of warfare lies at sea, in the battle for control of maritime trading routes.
Global arms spending soared to over $2.2 trillion last year. Japan's defense budget has jumped to its highest levels since 1960. The period between 2024 and 2027 will be a dangerous window of crisis over Taiwan.
China has increased military expenditure by two thirds over the past decade. Much of that has gone on expanding and modernizing its navy. China can now claim to have the world's largest fleet of operational warships and submarines.
The Russians are constructing icebreakers for when Arctic warming opens a viable trading route in the high north. The route could deepen Russian cooperation with China. Putin could declare much of the Arctic Ocean to be Russian territorial waters.
Maritime chokepoints are vulnerable as trade shuttles between Asia and the rest of the world. The possibility of a hostile blockade of the Malacca Strait haunts Beijing.
On the Pacific rim, US marines are deploying rocket systems to cover the 200 km sea channel between the Philippines and Taiwan. There are big US bases in the Philippines.
The PLA has just completed military exercises that seemed to rehearse a blockade of Taiwan. A blockade is an act of war and risks a major US response. China would issue an ultimatum to Taiwan first, to raise the stakes for any US attempt to break the blockade.
As China risks naval confrontation, the West will find Taiwan hard to defend.

AR Britain should keep its naval assets away from the Pacific rim if it wants to secure its home base on the Atlantic rim.

The UK and China

James Cleverly

No significant global problem can be solved without China. To give up on China would be to give up on addressing humanity's biggest problems. To declare a new Cold War would be a willful misunderstanding of the modern world.
When Britain condemns the mass incarceration of the Uighur people in Xinjiang, I hope our Chinese counterparts do not believe that we are merely seeking to interfere in their domestic affairs. But when the Chinese government locks up over a million people, this stirs our revulsion.
We expect China to observe the laws and obligations it has freely accepted. If China breaks them, we are entitled to say so and to act, as we did when China dismantled the freedoms of Hong Kong. Peaceful co-existence begins with respecting fundamental laws and institutions.
As UK foreign secretary, I urge China to be open about the doctrine and intent behind its military expansion. Transparency is surely in everyone's interests. Secrecy can only increase the risk of tragic miscalculation.

The EU and China
Wolfgang Münchau

Germany, France, and Italy account for more than a half of EU GDP and are China's largest trading partners in the EU. German chancellor Olaf Scholz, French president Emmanuel Macron, and Italian prime minister Giorgia Meloni all agree on close industrial relations with China.
The EU must decide whether to follow the US into a confrontation with China, or whether to strive to become more independent of the US. Since 1999, the US has developed the instrument of financial sanctions as a security policy tool and is ready to use it against Europeans.
Europe depends on the US for its defense and must ask whether a future US administration will want to align with Europe. But I see no way the EU can fully align with the US in a conflict with China over Taiwan. The EU economy is too dependent on China.

AR I urge the UK and the EU to find a shared position on China.

Cosmic Neutrinos

Martin Bauer

Experiments around the world detect solar neutrinos, but neutrinos released just after the Big Bang have far less energy and have so far proved impossible to detect.
The primordial plasma was a fog. Photons were soon absorbed or scattered. As the universe expanded and the plasma cooled, it became less dense, until about 12 Ts ABB, when the photons could finally fly free. We see them as the cosmic microwave background. The CMB is the oldest light we can see.
Neutrinos could fly free much earlier ABB compared with light. Neutrinos created in the first second ABB could immediately fly free, and still do. This cosmic neutrino background is the CNB. Discovering the CNB would be a new way of seeing how the universe developed.
Neutrinos come in three different types, each with its own tiny mass. CNB neutrinos would travel at a range of speeds, all around 0.1% of c, as they stream toward us, with courses bent by gravitational lensing. We could use them to image the large-scale structure of the universe at different times.
We think the CNB is as inevitable as the CMB. We must try to detect it. But the energy of cosmic neutrinos would be a billion times smaller than the lowest energy neutrino from other sources that we have observed so far, making them much harder to catch.
A neutrino hitting an atom can transform a proton into a neutron, changing the chemical identity of the atom. Cosmic neutrinos are not energetic enough to do this, but tritium is unstable. If a tritium nucleus absorbs a cosmic neutrino before it decays, the energy of the electron it emits can be higher than expected. If we could precisely measure the energy, we would have discovered the CNB.
A target of 100 g of tritium would yield just 4 neutrino absorptions per year. A research collaboration called PTOLEMY aims to build a prototype detector.

AR An opportunity for the deep future.

Mathematics and Music

A Zee

The universe is a book written in the language of mathematics .. Trying to understand physics by reading popular books is like reading about music without ever listening to it. Nature is singing to us, and generations of people far more intelligent than most of us have discovered the language, however imperfect, that enables us to listen. Perhaps it is not high fidelity .. but still, it conveys far more than any popular book written in human language could possibly convey.
Quantum Field Theory, as Simply as Possible by A Zee (p 341)

A popular book on physics
Michio Kaku

Journalists are hyperventilating about chatbots because they see that their job is on the line. Many jobs have been on the line historically, but now journalists are in the crosshairs.
Mother Nature does not compute digitally. Quantum computers should be able to unravel the secrets of life, the secrets of the universe, the secrets of matter, because the language of nature is the quantum principle.
The universal law of technology is that it can be used for good or evil. That's why we regulate nuclear weapons, because they would be enough to destroy humanity on planet Earth. At some point, we're going to reach the boundaries of chatbot technology, where it impacts negatively on society. Right now, I can see a lot of benefits.
The whole purpose of writing books for the public is so that they can make educated, reasonable, wise decisions about the future of technology. Once technology becomes so complicated that the average person cannot grasp it, then there's big trouble, because people with no moral compass will be directing it.
I was fascinated by Einstein's dream of a theory of everything, a unified field theory. I said to myself, when I grow up, and I become a theoretical physicist, I want to write papers on this subject. But I also want to write for myself as a child.

2023 Earth Day

The Environment

Denis Hayes

Earth Day has changed. In 1970, we were focusing on the fact that schoolchildren were not allowed to go outside for recess because the air was too filthy, that streams that people swam and fished in were no longer accessible because they were laced with poison, and we were spraying everything with pesticides.
Today, the big global issues like climate change and the epidemic of extinctions are more in tune with Earth Day, somewhat akin to the threat of thermonuclear war was when I was young. Millions of people every year come out and do something positive for the environment.

Fix your diet, save the planet
Peter Singer

The year of the first Earth Day, 1970, was the year I stopped eating meat. I realized that there is no ethical justification for treating animals like machines for converting feed into meat, milk, and eggs. It is wrong to ignore or discount the interests of other sentient beings.
Boycotting the monstrous abuse of billions of animals each year is a powerful reason for not eating meat, but the outsize contribution of meat and dairy products to climate change is for me now an equally urgent part of shifting to a plant-based diet.
Meat and dairy production are major sources of methane, a powerful greenhouse gas. Releasing into the atmosphere a ton of methane will, over a century, raise the temperature of our planet by 28 times as much as releasing a ton of carbon dioxide.
We can do something for the planet every time we eat. If Americans were to replace half of all animal-based foods with plant-based alternatives by 2030, that alone would help them get a quarter of the way toward hitting the US climate target under the Paris agreement.
A decision to stop eating animals makes a fitting Earth Day resolution. Cattle grazing is the largest driver of deforestation of the Brazilian Amazon. In addition to the substantial carbon emissions, the destruction of tropical forests threatens mass extinctions.
In 1975, it was rare to encounter a vegetarian in Western societies. Now there are 1.3 million vegans in Britain, or 2% of the UK population. In the United States, estimates of the proportion of vegans in the population range from 0.5% to 6%.
Even if there were 10 times as many vegans in the world, that would not be enough to save the planet or end factory farming. Persuading most people to halve their consumption of animal products would achieve much more.

Manfred Weber

Eine erfolgreiche Chinastrategie ist heute nur in Abstimmung mit den USA denkbar. Die EU kann China derzeit weder politisch noch militärisch allein begegnen.
Sollte es eine Eskalation zwischen China und Taiwan geben, muss sich die EU auf die Seite der Demokratie stellen. Führungen wie die in China und Russland verstehen nur die Sprache der Stärke. Die EU müsste im Fall eines Überfalls Chinas auf Taiwan zu massiven Sanktionen bereit sein.
Dass Rohstoffabhängigkeiten einen härteren Kurs unmöglich machen, wurde früher auch über Russland behauptet. Das stimmte schon damals nicht, und es ist auch pauschal in Bezug auf China falsch.

Financial Times

US Treasury secretary Janet Yellen warns that any effort to decouple from China would be "disastrous" and calls for a "constructive and fair" economic relationship: "The US will assert ourselves when our vital interests are at stake. But we do not seek to decouple our economy from China's. A full separation of our economies would be disastrous for both countries. It would be destabilizing for the rest of the world."

Britain vs China
Martin Kettle

UK foreign secretary James Cleverly is pushing Conservative foreign policy toward a more practical and stable place in world affairs. He says it is in no one's interest "to just pull the shutters down" on relations with Beijing: "We have got to − and therefore we will − engage closely and regularly."
China is now the great new threat feeding Brexiteer nationalism. But economic stagnation and the Ukraine war underscore the fact that British interests depend on restored trade and effective alliances. Britain is not a Pacific power, Russia is a hostile state, the US future remains uncertain, and liberal democracies need to stick together. There is no role for a maverick Britain.

Three Nuclear Superpowers

David E Sanger, William J Broad, Chris Buckley

US State Department: "The United States is entering one of the most complex and challenging periods for the global nuclear order, potentially more so than during the Cold War."
Pentagon policy document: "By the 2030s the United States will, for the first time in its history, face two major nuclear powers as strategic competitors and potential adversaries."
Joint Chiefs of Staff chairman General Mark Milley: "We are probably not going to be able to do anything to stop, slow down, disrupt, interdict, or destroy the Chinese nuclear development program that they have projected out over the next 10 to 20 years."
New START runs out in 2026. There is little chance of forging a new treaty while the Ukraine war rages. Even if Russia and the United States did so, it would be worthless without China. The Chinese nuclear warhead count could grow to 1,000 by 2030.
China is building three vast fields of missile silos in its arid northern expanses. They could hold up to an estimated 350 ICBMs, each armed with MIRVs. The solid-fuel missiles in the silos are likely to have their warheads attached, reducing time to launch. China is also working on a new generation of submarines for launching missiles.
Russia and the United States are now down to 1,550 long-range nuclear weapons each. But Russia is upgrading its arsenal into a far more survivable force. And the United States is overhauling its arsenal for an estimated cost of $2 trillion.

Michael Evans

Top US Indo-Pacific commander Admiral John Aquilino: "Conflict in the INDOPACOM area of operations is neither imminent nor inevitable. Nevertheless, we do not have the luxury of time. We must act now to maintain a free and open Indo-Pacific."
Under the one-China policy, the USA recognizes the PRC as the sole legal government of China but only acknowledges the Chinese position that Taiwan is part of China. Washington maintains unofficial relations with the Taipei government and supplies arms to Taiwan.
Aquilino: "Beijing publicly claims a preference for peaceful unification over conflict. However, its consistent pressure tactics and coercive behavior demonstrates a significant disconnect between their words and their deeds .. Construction of silo fields across northern China, coupled with modern ballistic-missile submarines and the Xian H‑6N .. bomber, underscore China's focus on developing a survivable nuclear triad."

Freedom Over Tyranny

Simon McDonald, Christoph Heusgen, Stéphane Abrial, Jim Jones, Stefano Stefanini

Vladimir Putin has flagrantly violated international law and committed a breach of the UN charter. He used massive force to try to erase Ukraine from the map of Europe, leaving a trail of gross human rights abuses and war crimes in the process.
At this year's Munich security conference, transatlantic leaders affirmed that Ukraine must win this war. But a declaration of support is not enough. We have to provide Ukraine with the combined force of tanks, missiles, and aircraft to conduct a successful counterattack, paving the way to Ukrainian victory and peace negotiations on acceptable terms.
We should be wary of China's role in this conflict. Beijing is already helping Putin's war efforts and has every interest in keeping Putin in power. To deter Russia and China, Europe needs to strengthen European defense capabilities. A stronger European contribution is also necessary to help preserve bipartisan US support for Ukraine.
Putin has become an international outcast. To continue its fight for freedom and defeat him, Ukraine needs more support. When freedom is better equipped than tyranny, its victory is assured.

Meta AI Reads Proteins

Singularity Hub

Meta AI has used a a transformer protein language model to decipher proteins in bacteria, viruses, and other microorganisms. Its ESMFold system is like ChatGPT.
Proteins are made from 20 amino acids strung like beads on a string. The amino acid letters help shape the final structure of a protein. An evolutionary dictionary helps string them into structures the body can use.
Meta AI fed ESMFold with sequences of known proteins. The AI learned the general architecture of proteins and saw roughly 65 million different protein sequences overall.
When the team hid certain letters, ESMFold filled in the blanks and learned to understand evolutionary protein sequences and how they work together to make functional proteins. On standard test sets, ESMFold provided prediction accuracy matching AlphaFold2 on more than half the proteins.
The team then pushed into metagenomics to study DNA from environmental sources. ESMFold has predicted over 700 million of these proteins.

Beijing officials say China is open for business. Westerners are exploring how they might reduce their dependence on China.
China's tacit support for Russia's invasion of Ukraine sharpened fears in Europe that China might weaponize its economic and trade relationships in pursuit of political ambitions.
China has a "Made in China 2025" policy of industrial development and a policy of dual circulation to shift effort away from exports in favor of expanding domestic demand, growth, and innovation.
In the United States, sentiment has hardened into confrontation. The EU says China is a cooperation and negotiation partner, an economic competitor, and a systemic rival.
For the West, the shared benefits of globalization based on mutual trust now look fragile as trust gives way to mutual suspicion and retaliatory spats.

Trusting China

Thomas L Friedman

Trust plays a big role in international relations, now that so many goods and services traded worldwide are digital, and therefore dual use.
In China, the Communist Party (CPC) has a stronger grip than ever. It crushes any challenge to its rule or to President Xi Jinping. Its hold is a product not only of all the hard work and savings of the Chinese people but also of an increasingly pervasive police state and a government that has steadily raised standards of living. The CPC takes both control and nation-building seriously.
China and America are jostling to acquire the most economic and military clout to shape the 21st century. The nations have become as economically intertwined as the strands of a DNA molecule. Neither China nor America has ever had to deal with an economic and military peer with which it was so intertwined through trade and investment.
In our new technological ecosystem, ever more of the devices and services we use are driven by microchips and software and connected through data centers in the cloud. The microchips are critical. The that can make the fastest, most powerful, and most energy efficient microchips can make the biggest AI computers and dominate in economics and military affairs.
Because the physics of making advanced logic chips has become so complex, no one country or company can own the whole supply chain. You need the best from everywhere, and that supply chain is so tightly intertwined that each company must trust the others intimately.
Taiwan hosts the world's greatest chip-making company, Taiwan Semiconductor Manufacturing Company. TSMC makes 90% of the world's most advanced logic chips. It takes the designs of the most advanced computer companies in the world and turns them into chips. It makes two pledges to its customers: TSMC will never compete against them by designing its own chips and it will never share the designs of one of its customers with another.
By working with so many trusted partners, TSMC leverages their steadily more complex designs to improve itself. This requires tight collaboration between TSMC and its customers and suppliers.
China has Semiconductor Manufacturing International Corporation, but no global chip designers trust SMIC with their most advanced designs, so it is at least a decade behind TSMC.
China made itself a less trusted partner right when the most important technology for this century required unprecedented degrees of trust. When Xi Jinping centralized power into his own hands, reinforced the authority of the CPC, and deployed pervasive surveillance technologies, whatever trust China had built up with the West evaporated.
Beijing officials say that US politicians blamed US economic troubles not on any educational deficiencies, or a poor work ethic, or automation or the 2008 looting by financial elites, but on Chinese exports to America. Americans then imposed controls over advanced semiconductor manufacturing and other high-tech exports to keep China behind.
Both sides must see that establishing and maintaining trust is important.

AR Absolutely right, as usual from Friedman.

Hyperdimensional Computing

Anil Ananthaswamy

Artificial neural networks (ANNs) are power-hungry and lack transparency. Their limitations have long been obvious.
Consider an ANN that tells circles and squares apart. It may have two neurons in its output layer, one for a circle and one for a square. To distinguish blue or red you need four output neurons, one for each combination. More features mean even more neurons.
In a different approach, hyperdimensional computing represents each piece of information as a hyperdimensional vector. A vector is simply an ordered array of numbers. An array of N numbers represents a point in N‑dimensional space.
For images with red circles and blue squares, choose distinct vectors to represent properties and their values. Distinctness is quantified by orthogonality. In an N‑dimensional space, there are N mutually orthogonal vectors. If we allow vectors to be nearly orthogonal, the number of such distinct vectors in the space explodes.
Given hypervectors for shapes and colors, we can manipulate them using multiplication, addition, and permutation. These are enough to create an algebra of hypervectors for symbolic reasoning.
Hyperdimensional algorithms can solve problems symbolically. They tolerate errors well and are at least 10 times more tolerant of hardware faults than traditional ANNs. They are also transparent.
Hyperdimensional computing is well suited for a new generation of hardware. It is still in its infancy.

AR This is a natural step forward from what we did in my team at SAP.

Juice

European Space Agency

ESA's Jupiter Icy Moons Explorer (Juice) spacecraft lifted off on an Ariane 5 rocket from Europe's Spaceport in French Guiana at 12:14 UTC. The launch marks the beginning of an ambitious voyage to uncover the secrets of the ocean moons orbiting Jupiter.
Juice project manager Giuseppe Sarri: "It is thanks to the leadership of ESA and the effort and commitment of hundreds of European industries and scientific institutions that the Juice mission has become a reality."

Life on the Jovian moons
Ian Sample

Juice has blasted off on a landmark mission to Jupiter's moons. The mission aims to uncover the secrets of Jupiter's Great Red Spot, its enormous polar auroras, and how its mighty magnetic field shapes conditions on the gas giant's nearby moons.
Juice will visit three of Jupiter's moons − Europa, Callisto, and Ganymede − to explore the deep liquid water oceans beneath their icy surfaces. The moons are high the list of local worlds that might host life. Any hydrothermal vents on their ocean beds could provide energy for life to evolve.
UCL Mullard Space Science Laboratory professor Andrew Coates: "I'm so thrilled to see Juice finally on its way. This is an excellent mission to look at habitability of Jupiter's moons."

AR Glorious, but I may be too old to witness the results of the mission.

Big Data + Compute = Godlike AI

Ian Hogarth

Godlike AI is a superintelligent computer that learns and develops autonomously, that understands its environment without the need for supervision, and that can transform the world around it. Godlike AI could be a force beyond our control or understanding. It could destroy the human race.
The compute used to train AI models has increased by a factor of 100 million in the past 10 years. We have gone from training on relatively small datasets to feeding AIs the entire internet. AI models have progressed from beginners to being superhuman at a huge number of tasks.
Large language models are AI systems that can generate, classify, and understand text. They are dangerous partly because they can mislead the public into taking synthetic text as meaningful. They are also beginning to demonstrate complex capabilities, such as finding ways to deceive us.
DeepMind was founded in London in 2010 and bought by Google in 2014 for more than $500 million. OpenAI was founded in 2015 in San Francisco. Late in 2022, its ChatGPT began making headlines. Since then, a huge wave of capital and talent has shifted toward AGI research.
OpenAI, DeepMind, and others try to mitigate existential risk by AI alignment. But the number of people working on AI alignment research is vanishingly small.
Distributed AI Research Institute founder Timnit Gebru: "Trying to build AGI is an inherently unsafe practice. Build well-scoped, well-defined systems instead. Don't attempt to build a God."
In engineering biology, "gain-of-function" research on biological viruses is subject to strict international regulation. This is the strictest form of oversight. The development of new drugs is regulated by a government body that demands clinical trials. We could approach godlike AGI systems like virus research, while narrowly useful AI systems could be regulated like new drugs.
Labs are waiting for new hardware to train bigger models using more compute. We will see many new emergent capabilities. Time is short for governments to take control.

A vastly worse flash crash
David Wolpert

Everybody is debating whether there will be an AGI that can reach our level. In the "flash crash" of 2010, stock markets fell by trillions of dollars in minutes before recovering. It was caused by a lot of bots that do automated trades. Vastly more complicated versions of the flash crash can ensue when the bots are replaced by new intelligent machines.
By the year 2100, we won't be the most intelligent creatures on Earth.

AR Ominous − governments need expert advice.

Biden Visit Ireland

The Times

President Joe Biden of the United States spoke at the Ulster University Belfast campus today to mark 25 years since the Good Friday agreement. He paid tribute to UK prime minister Rishi Sunak and European Commission president Ursula von der Leyen for the Windsor Framework, which he said was an "essential step" to "preserve and strengthen" the Good Friday agreement.
Biden: "As a friend, I hope it's not too presumptuous for me to say that I believe democratic institutions established by the Good Friday agreement remain critical for the future of Northern Ireland .. An effective devolved government .. is going to draw even greater opportunity in this region. So I hope the assembly and the executive will soon be restored."

European Sovereignty

The Times

President Emmanuel Macron of France urges Europe to break free from its economic dependence on the United States and China. He says China and the US both threaten the "strategic autonomy" he sees as vital for the "sovereignty" of the EU.
In China last week, he said the EU should be a third superpower. He attacked Russia's "barbaric" invasion of Ukraine but did not mention Taiwan.
Macron says Europe must have a vigorous industrial policy: "The US has one. China has one .. Europe must have one to be sure that you are not trapped in a crazy situation the day something happens .. We want allies. We want to be good friends. We want partners. But we always want to be in a situation to choose them, not to be 100% dependent on them."
German SDP parliamentary group: "It's a grave mistake for the West to allow itself to be divided in its approach to Beijing, of all things. This weakens our western community of values."

AR I would rather see China, the US, and the EU recognise their interdependence as time zones in a single planetary political economy.

Phenomenology of Geist

Robert B Brandom

For Hegel, Geist denotes everything that has a history rather than a nature. Geist is all of our properties, doings, and institutions, specified in a suitable normative vocabulary.
For him, the history of Geist boils down to its transformation from a traditional to a modern form. He saw the scientific, economic, political, and social manifestations of the advent of modernity.
Hegel thinks the transition from traditional to modern culture was expressively progressive. But he says traditional communities had Sittlichkeit. The absence or opposite of Sittlichkeit is alienation. A third stage in the progressive development of Geist would preserve the modern appreciation of subjectivity while reachieving Sittlichkeit.
Hegel: "Human law in its universal existence is the community, in its activity in general is the manhood of the community, in its real and effective activity is the government .. Since the community only gets an existence through its interference with the happiness of the family .. it creates .. an internal enemy − womankind in general."
He thinks traditional society is distinguished by its taking natural distinctions as immediately and intrinsically having normative significance. The decisive move to modernity is acknowledging the significance of normative attitudes and practices in constituting norms and normative statuses.
The example he chooses is gender essentialism. Hegel deserves a place in the feminist pantheon.

QED

A Zee

What happens when we couple the photon and the electron? We could have disturbed the 4D electro­magnetic field A by coupling it to the 4D current density J, but the electron is now a field.
Dirac wrote J^μ = ψ*γ^μψ to give the coupling action:
S_coupling = ∫ d⁴x e ψ*(x)γ^μψ(x)A_μ(x)
Here e is not Euler's number but an experimentally measured coupling constant (e ≊ 0.303). Thanks to charge conservation, this action predicts the existence of the positron. Its experimental discovery was a triumph for Dirac's new theory of quantum electrodynamics (QED).
Our experience of physical phenomena originates essentially from zillions of photons interacting with zillions of electrons. At a fundamental level, all of that fantastic richness of the world is determined by the interaction vertices in the simplest Feynman diagrams.
Here is the action describing how electrons and photons interact:
S_QED(ψ, A) = S_Maxwell(A) + S_Dirac(ψ) + S_coupling(ψ, A)
The resulting quantum field theory is QED.
Quantum Field Theory, as Simply as Possible by A Zee (pp 153−157)

The Dirac Equation

Andy Ross

Today I've understood the way the Dirac equation for the electron works (more or less). The equation was Paul Dirac's pride and joy, but despite battling with his textbook I've been baffled by its intricate notation until reading a casual account in an introductory book on QFT by A Zee.
Here is how his famous equation is often presented:
(iγ^μ∂_μ − m)ψ = 0
The ψ term is the probability amplitude (like the Schrödinger wave function) written as a spinor (with 4 components), the γ terms (4 in total, says the μ) are the Dirac matrices (with i = √−1, as usual), the partial differential operators cover dimensions t, x, y, z (the μ superscript and subscript use the Einstein summation convention), and m is the electron mass.
All this is shorthand for four coupled partial differential equations for the variations (in each of the 4 dimensions) of the spinor components u₁, u₂, v₁, v₂.
The Dirac matrices simply assign +, −, and i signs correctly within these differential equations, and the four equations together describe an electron moving freely.
To get the dynamics, see that the action is given by:
S_Dirac(ψ) = ∫ d⁴x ψ*(iγ^μ∂_μ − m)ψ
The * with ψ indicates complex conjugation (a little bar over ψ is not supported in my HTML coding). The equation of motion for the electron follows relatively easily. (Richard Feynman had messed up his presentation of all this with an inscrutable slash notation.)

Heidegger Condemned

Lyndsey Stonebridge

Russian philosopher Alexander Dugin is a scholar of German philosopher Martin Heidegger. Dugin is sometimes called Putin's brain and is in no doubt about the existential importance for Russia of its war in Ukraine.
Heidegger's ideas about Being in a rootless world ripped up the ground of philosophy. Forget struggling for the big metaphysical ideas behind the words of philosophers, he said. Reason had left the modern world poorer. The truth exists only in our Being.
See yourselves for what you are, Heidegger urged, thrown into a world to which you can only respond. Only then can the struggle for an authentic life truly begin. Existentialism inherited his legacy with calls to seize the meaning of being back from the senselessness of modern life.
In 1933, Heidegger joined the Nazi party and became rector of Freiburg University. His philosophy found a new home for ideas about race and the German Volk and about work, struggle, and living space. The rootlessness of modern life could be resolved by the myths of National Socialism.
In 1949, Heidegger described how the impersonal forces of technology and rationality continued to work: "Hundreds of thousands die en masse. Do they die? They perish. They are cut down. They become items of material available for the manufacture of corpses."
Heidegger died in 1976. When his Black Notebooks were published in 2014, he was revealed as an antisemite, a German exceptionalist, and a mystical obscurantist. By then, Dugin was evoking Heidegger in Russian politics.

AR Existentialism is close to nihilism.

Resurgence in Quantum Theory

Charlie Wood

Jean Écalle, now 73, wrote visionary mathematics that might resolve a problem in quantum theory.
Quantum fields are complicated. Their ripples can, in principle, appear at any moment, in any number, and with any energy. In QED, an infinite string of Feynman diagrams represents a parade of increasingly unlikely quantum possibilities using perturbation theory.
An infinite power series involves a certain critical value x, then x squared, x cubed, and so on, all multiplied by different coefficients:
F(x) = a₀ + a₁x + a₂x² + a₃x³ + .. + a_ixⁱ + ..
For QED, the value of x is alpha, where α = 1/137. Raising this number to larger powers shrinks the terms rapidly. Feynman diagrams give us the coefficients a_i for each term.
The vacuum constantly produces transient pairs of ripples with positive and negative charges. Those ripples normally attract each other and vanish. But if alpha becomes negative, the ripples push each other apart and become real particles. This triggers an explosive disintegration of the vacuum.
If a series diverges for small negative x then it should also diverge for small positive x. This way of handling QED goes to infinity. Higher terms lead to factorial growth in the number of Feynman diagrams. This growth drives the sum toward infinity.
Even the simplest QFT inevitably diverges. Divergent series include exponentially small terms beyond all orders. These terms are beyond the reach of perturbation theory.
Écalle developed an "alien calculus" for divergence. Resurgence lets us dig into the distant terms of an asymptotic series and uncover enough to define a unique function:
1  Write the perturbative series. The terms shrink at first, then grow rapidly. Plot the growth to find it is almost factorial. Study the difference from factorial growth to find the first nonperturbative term.
2  Do a Borel resummation to eliminate the factorial growth. The perturbative terms should grow exponentially, but not exactly. The deviation comes from a new asymptotic series, which you multiply by the first nonperturbative term.
3  Strip the exponential growth from the perturbative data and look for further deviations that reveal a second nonperturbative term. Look closer to find that this nonperturbative term comes with yet another asymptotic series.
4  Continue to find as many nonperturbative terms with asymptotic series attached as you can to get a trans-series.
Resurgence suggests that exact results could exist for QFT. It has already produced new results in quantum mechanics.

AR I find this exciting − a potential breakthrough.

Zelensky: "You have not abandoned Ukraine, you stood with us shoulder to shoulder, and we are grateful to you. We believe this is a historic relationship."
Poland has taken in more than a million Ukrainian refugees since Russia invaded. It has helped prompt western powers to supply battle tanks to Ukraine and has also delivered fighter jets to Ukraine. Zelensky will sign bilateral agreements on support and economic cooperation.

Finland Joins NATO

Finland has become a member of NATO. Foreign ministers of member states welcomed Finnish leaders at the NATO headquarters in Brussels today, the 74th anniversary of the Washington Treaty.
President Niinisto of Finland: "The era of military non-alignment in our history has come to an end. A new era begins. Russia tried to create a sphere around them and, well, we are not a sphere."
Kremlin spokesman Dmitry Peskov: "This forces us to take countermeasures in tactical and strategic terms."
US secretary of state Antony Blinken: "This is maybe the one thing that we can thank Mr Putin for because, once again, he precipitated something he claims to want to prevent by Russia's aggression, causing many countries to believe that they have to do more to look out for their own defence and to make sure that they can deter possible Russian aggression. We are thrilled to have Finland as the 31st member of our alliance."

Will Russia Collapse Soon?

Richard Spencer

Ukraine's national security adviser Oleksiy Danilov says President Putin's summit in March with President Xi of China confirmed what Ukraine long believed: that Russia is weak and at risk of falling apart: "It is a historic process and you can't stop history."
Danilov says Putin's failure to capture Kyiv and Kharkiv in the initial invasion was a death blow to Russian unity. Russia would lose control of the parts of eastern Ukraine it occupies and its possessions in the Caucasus. Russia has already lost its power over allies in central Asia, and China has its eyes on the Russia's Siberian far east.
Danilov: "Letting China take Russian territory will be dangerous for the West because by unlocking one problem they will create another. There needs to be initial steps by the West now."
On his visit to Moscow, Xi said nothing about providing weapons or military support to Russia.
Danilov: "China is a big country and will be a mighty rival to the Anglo-Saxon world. Now it's the owner of Russia. Russia will no longer undertake any important action without them. Russia fully lost its sovereignty."
Russia's failure to prosecute its war in Ukraine successfully has strengthened China's hand. China's peace plan made no explicit demand for Russian troops to withdraw, but it emphasised respect for national sovereignty and demanded an end to nuclear threats.
Europe is running low on equipment to provide Ukraine after this year. If Ukraine manages to inflict a major defeat, the threat remains that Putin could turn to nuclear weapons.
Danilov: "If the Chinese let Russia use nuclear weapons, they will use them. If not, they won't."

AR A hint of wishful thinking, but collapse is possible.

Bees Are Sentient

Annette McGivney

Stephen Buchmann is a pollination ecologist. His 2023 book What a Bee Knows depicts bees as showing emotions resembling optimism, frustration, playfulness, and fear. They can recognize different human faces, process memories while sleeping, and maybe even dream.
The US Department of Agriculture considers commercially managed bees as livestock. Colony collapse disorder has greatly reduced the population of bees in the last two decades. The decline is primarily attributed to pesticide use, but Buchmann says it is also due to psychological stress.
A bee's brain is the size of a poppy seed, but new technology lets us analyze its neurobiology. Before these innovations, most scientists studying bees regarded them as little robots.
Lars Chittka is a London professor in sensory and behavioral ecology. His 2022 book The Mind of a Bee reported his research on how bees learn and process information. His lab explored how bees learn to avoid predators: A robotic crab spider prompted bees to scan flowers for spiders before landing.
Chittka and others studied bee behavior in response to fluctuations in dopamine and serotonin. When bees received a reward of sucrose, they had more zest for foraging than bees who received no reward. When bees were shaken in a tube, dopamine and serotonin decreased.
Buchmann: "Bees are self-aware, they're sentient, and they possibly have a primitive form of consciousness. They solve problems and can think. Bees may even have a primitive form of subjective experiences."
Chittka: "These unique minds .. have as much justification to exist as we do."

Humanism

Rowan Williams

A humanist creed was drafted by the 19th-century American Robert Ingersoll: "Happiness is the only good. The time to be happy is now. The place to be happy is here. The way to be happy is to make others so."
Hard moral questions arise. Making others happy proved a more tangled matter than many humanists expected. Some will claim happiness in ways that damage others, and what it might mean to make them happy is by no means simple.
The human landscape is enriched by symbol and tradition and not easily reducible to rational functionality. The boundaries between religious and secular readings of the world are more porous than either side often supposes.
Humanity is damaged: Something utterly extraordinary, creative, resplendent, free, and loving has been lethally infected with delusions and compulsions.

AR Sad but true, in my humble opinion.
