This is the fascinating story of the development of Standard Model of particle physics between Dirac's prediction of the positron in 1928 and the introduction of the six-quark model in 1973, as described in the primary sources. The Standard Model of particle physics is the theory describing three of the four known fundamental forces in the universe (electromagnetic, weak and strong interactions - excluding gravity), and classifying all known elementary particles.

Produktbeschreibung
This is the fascinating story of the development of Standard Model of particle physics between Dirac's prediction of the positron in 1928 and the introduction of the six-quark model in 1973, as described in the primary sources. The Standard Model of particle physics is the theory describing three of the four known fundamental forces in the universe (electromagnetic, weak and strong interactions - excluding gravity), and classifying all known elementary particles. Although the Standard Model has demonstrated some success in providing experimental predictions, it leaves some physical phenomena unexplained and so falls short of being a complete theory of fundamental interactions. This analysis of the failures of the Standard Model suggest that they stem from the attempt to base it on relativistic quantum field theory and make it Lorentz covariant, and the reliance on renormalization to remove infinities and bring theoretical values in line with experimental ones. Part I describes the development of the Standard Model from the Bohr model of the atom in 1913, based on what were believed to be 3 stable particles, electrons in orbit around a nucleus comprised of protons and neutrons, to its emergence in 1973 as the six-quark model, comprising 52 elementary particles and anti-particles, of which only the electron is believed to be stable. Part II introduces an alternative, Supersymmetry; and Part III introduces, String Theory, neither of which fare any better.

Autorenporträt
Trevor Underwood was born in England in 1943, and became a US citizen in 2004. He earned a M.A. in mathematics and physics at Cambridge University in 1965, and a M.Sc. in economics at the London School of Economics in 1967, followed by further graduate studies at the University of Rochester, NY, and at Harvard University. He worked for the Bank of England, the International Monetary Fund, and the UK Treasury between 1969 and 1973. He founded a treasury consultancy and software company in 1974, which he ran until 2017. In 2008 he returned to scientific research. In November 2015, he published a paper "A new model of human dispersal" on bioRxiv.org, the online preprint archive for biology run by Cold Spring Harbor Laboratory. He then wrote six climate science papers which were published in a book (November 2019) "The Surface Temperature of the Earth". In December 2021, he published "Urbain Le Verrier on the Movement of Mercury - annotated translations". This was followed by a series of reviews of theoretical physics: (April 2023) "Quantum Electrodynamics - annotated sources. Volumes I and II"; (June 2023) "Special Relativity"; (November 2023) "General Relativity"; (March 2024) "Gravity"; (May 2024) "Electricity & Magnetism"; (July 2024) "Quantum Entanglement"; and (September 2024) "The Standard Model"; culminating in his conclusions in (October 2024) "New Physics". In November, 2024, he published "Cosmological Redshift of Light".
