Feynman, Richard P, and Albert P Hibbs, Quantum Mechanics and Path Integrals, McGraw Hill 1965 Preface: 'The fundamental physical and mathematical concepts which underlie the path integral approach were first developed by R P Feynman in the course of his graduate studies at Princeton, ... . These early inquiries were involved with the problem of the infinte self-energy of the electron. In working on that problem, a "least action" principle was discovered [which] could deal succesfully with the infinity arising in the application of classical electrodynamics.' As described in this book. Feynam, inspired by Dirac, went on the develop this insight into a fruitful source of solutions to many quantum mechanical problems.

Heyes, Cecilia, Cognitive Gadgets: The Cultural Evolution of Thinking, Belknap Press: Harvard University Press 2018 “Cecilia Heyes presents a new hypothesis to explain the one feature that distinguishes Homo sapiens from all other species: the mind. Through lucid, compelling writing, this masterly exegesis proposes that the key features of the human mind, termed ‘cognitive gadgets,’ are the products of cultural rather than genetic evolution. It will stimulate its readers to think deeply, as Heyes has done, about what it means to be human.”―Lord John Krebs, University of Oxford

Brian Seibert, She's the Queen of Tap. Is Her Moment Now?, ' While nothing is missing from Dormeshia’s dancing, a few years ago, she began to sense that something important was missing from tap today. In classes she taught across the world, she noticed that students were often technically impressive and “saying a lot of things,” yet lacking something fundamental — swing. Swing is a notoriously hard term to pin down. Let’s just say that it’s a groove or rhythmic feel central to jazz — and, because tap and jazz developed together, central to tap. And yet many young tap dancers, were “completely unaware of swing,” Dormeshia said. They didn’t know what it was, much less how to embody it.' back

Camille Nelson, Friday Essay: George Eliot 200 years on - a scandalous life, a brilliant mind and a huge literary legacy, ' When Dorothea, in all her married misery, is confronted by an extraordinary vision of a suffering human society, we encounter one of the most heartbreakingly beautiful passages in Eliot’s ouevre. She writes,

If we had a keen vision and feeling of all ordinary human life, it would be like hearing the grass grow and the squirrel’s heart beat, and we should die of that roar which lies on the other side of silence. As it is, the quickest of us walk about well wadded with stupidity.

CERN, LHC Homepage, 'The Large Hadron Collider (LHC) sits in a circular tunnel 27 km in circumference. The tunnel is buried around 50 to 175 m. underground. It straddles the Swiss and French borders on the outskirts of Geneva. The first collisions at an energy of 3.5 TeV per beam took place on 30th March 2010. The LHC is designed to collide two counter rotating beams of protons or heavy ions. Proton-proton collisions are foreseen at an energy of 7 TeV per beam. The beams move around the LHC ring inside a continuous vacuum guided by magnets. The magnets are superconducting and are cooled by a huge cryogenics system. The cables conduct current without resistance in their superconducting state. The beams will be stored at high energy for hours. During this time collisions take place inside the four main LHC experiments.' back

Hermann Weyl - Wikipedia, Hermann Weyl - Wikipedia, the free encyclopedia, 'Hermann Klaus Hugo Weyl (9 November 1885 – 8 December 1955) was a German mathematician. Although much of his working life was spent in Zürich, Switzerland and then Princeton, he is associated with the University of Göttingen tradition of mathematics, represented by David Hilbert and Hermann Minkowski. His research has had major significance for theoretical physics as well as pure disciplines including number theory. He was one of the most influential mathematicians of the twentieth century, and an important member of the Institute for Advanced Study during its early years.' back

John Quiggin, Please, no more projections. What we need are predictions, and they're harder, 'Perhaps the most significant example of repeated failed projections has been the International Energy Agency’s projections of the importance of renewable power – the proportion of electricity generated by solar and wind and other renewable sources other than hydro. Beginning in 1994, when generation from these sources was negligible, the Agency has produced estimates of the future share of renewables every two years. Read more: Getting projections right: predicting future climate Every two years, with striking regularity, the previous estimates have been exceeded (hugely) and the new set has been revised upwards. But never by enough. Each time the upward revision has been inadequate. back

Matthew Avery Sutton, Explaining the bond between Trump and white evngelicals, ' White evangelicals’ pragmatic and self-serving approach to political power has been consistent for at least a century, dating to fundamentalists’ adoration for Warren G. Harding in the 1920s — which sounded a lot like their championing of Trump today. Although evangelicals preach family values and often claim moral superiority, history reveals that they are most interested in exercising political power and identifying politicians who help them do it. Evangelical leaders are sophisticated and pragmatic: Policy outcomes are what they really care about.' back

Paul Yip, The American civil war offered Hong Kong lessons in how to compromise and end conflict, ' Four years in, the Confederate state army, already disadvantaged in terms of manpower, industrial capacity and economy, was facing low morale, food shortages and exhaustion. Knowing this, General Ulysses S. Grant, who led the Union army, wrote to general Robert E. Lee, leader of the Confederate state army of northern Virginia, to persuade him to surrender. Lee negotiated surrender terms that allowed his men to keep their swords and personal belongings, and to return home in peace as long as they did not turn against the Union or break the law. These were generous terms for the men, who had expected to be imprisoned.' back

Pep Canadell, Hanquin Tian, Prabir Oatra & Rona Thompson, Nitrogen fertiliserd are incredibly efficient, but they make climate change a lot worse, ' Nitrous oxide (N₂O) (more commonly known as laughing gas) is a powerful contributor to global warming. It is 265 times more effective at trapping heat in the atmosphere than carbon dioxide and depletes our ozone layer. Human-driven N₂O emissions have been growing unabated for many decades, but we may have been seriously underestimating by just how much. In a paper published today in Nature Climate Change, we found global emissions are higher and growing faster than are being reported.' back

Sabine Hossenfelder, The Uncertain Future of Particle Physics, 'In 2012, experiments at the L.H.C. confirmed the discovery of the Higgs boson — a prediction that dates back to the 1960s — and it remains the only discovery made at the L.H.C. Particle physicists are quick to emphasize that they have learned other things: For example, they now have better knowledge about the structure of the proton, and they’ve seen new (albeit unstable) composite particles. But let’s be honest: It’s disappointing.' back

Simon Liburn & Philip Smith, turn down doe what? When you turn down the radio wgen your'e trying to park your car, ' One answer comes from a remarkable 1998 study by Anne-Marie Bonnel and Ervin Hafter. It builds upon one of the most successful theories in all psychology, signal detection theory, which describes how people make decisions based on ambiguous sensory information, rather like how a radar might detect a plane. One of the basic problems of radar detection is to work out whether it is more likely that what is being detected is a signal (an enemy plane) or just random noise. This problem is the same for human perception. Although apparently a metaphor like Broadbent’s filter, signal detection theory can be evaluated mathematically. The mathematics of human identification, it turns out, largely match those of radar operation.' back
