Paul Adrien Maurice Dirac OM FRS (/ d ɪ ˈ r æ k / ; 8 August 1902 – 20 October 1984) was an English theoretical physicist who is regarded as one of the most significant physicists of the 20th century. Decades later, even his close friend Leopold Halpern was surprised by this. A cache of letters, dated from 1934 to around 1960, exchanged between Dirac and the woman who was to become his wife. The supreme task of the physicist,’ Einstein declared, ‘is to arrive at the fundamental laws from which that universe can be built up by pure deduction.’ In The Universe Speaks in Numbers, Graham describes how Einstein’s successors are seeking these laws of nature with the help not only of new experimental results but also cutting-edge mathematics.

(“Dirac is the strangest man,” Bohr said, “who ever. 'Read the full review (registration required), 'If you like reading about math without having to do math, this is a stellar book.' When prompted by the chair of the session, Dirac responded: ‘that was a comment, not a question’. As the theorist Nima Arkani-Hamed says, ‘the universe speaks to us not only through experiments, but also through mathematics.’ These investigations, based squarely on quantum mechanics and special relativity, are taking theoreticians to extraordinary places and leading them to question many of our long-held beliefs about the fundamental nature of the universe. He inspected some six-hundred establishments, from tea-shops in Cumbria to over-priced bistros in Clapham to El Bulli in Catalonia. Phil Anderson was one of the most creative theoretical physicists of the past century. A specialist in the science of solids, he made influential…, 'In this fascinating and elegantly written book ... Farmelo has offered a thoughtful, well-informed reply to those who believe the quest for mathematical beauty has led theoretical physicists into adopting sterile, ultra-mathematical approaches divorced from reality. 'Crisply-written, entertaining and extraordinarily well-informed. Graham first heard about the subject of ‘The Strangest Man’ when he was fifteen years old. Dirac worked out a formulation of quantum mechanics, which includes Erwin Schrödinger's wave mechanics and Werner Heisenberg's matrix mechanics in 1926. 'Read the full review ($), 'A bird's-eye view of the panorama of modern physics … as authoritative as it is fascinating'.Read the full review, 'Farmelo is an authoritative, reliable and trusted guide... With a firm hand at the tiller, he cuts through the theoretical murky waters with panache. While theorists await guidance from new experimental information, many are investigating how new mathematics can help us to understand the order at the heart of the universe. Independent bookshops in UK unite to open new online bookstore to compete with Amazon. In this wonderfully rich correspondence, the deeply-private Dirac is remarkably candid about his inability to form warm relationships with other human beings. 'Read the full review, 'Farmelo has succeeded in writing a book for the general reader that gives insights into the motivation behind a theory developed by many of today’s leading thinkers. During a series of walking vacations in Italy, organized by the admirable ATG Oxford, he became extremely fond of fine coffee, made in the Italian style. ', 'Farmelo expertly narrates the history of the dynamic dance between mathematics and theoretical physics, from Newton to Einstein to string theory and beyond. Initially, he intended to write a brief and simple account of the mysterious relationship between physics and mathematics. ', 'A masterful exposition of the most productive relationship in all of science—the rich and rewarding interaction between physics and mathematics—with all its historical ups and downs, up to the frontiers of current research.'. His lecture ‘Paul Dirac and the religion of mathematical beauty’ at the Perimeter Institute in Waterloo, Canada is here. By the time the biography was complete, many of these witnesses were dead. Most physicists believe that any successful basic theory of nature must incorporate the two foundational theories of twentieth-century physics, quantum mechanics and the basic (special) theory of relativity. By contrast, the patterns sought by mathematicians may have nothing to do with reality. Inspired by the achievement of Paul Dirac, studied theoretical physics at Liverpool (BSc in 1974, PhD in 1977) and began to appreciate classical music, good food and the challenge of making a worthwhile contribution to fundamental science. It was only as a post-graduate student that Graham began to appreciate properly the beauty and revolutionary brilliance of Dirac, often called ‘the theorist’s theorist’.

Not only is mathematics ‘unreasonably effective’ in physics, as Eugene Wigner famously observed, the opposite is also true: physics is unreasonably effective in mathematics.

Formerly an academic, museum professional and undercover restaurant critic, Graham is an award-winning biographer and science writer. Or try to. Graham has contributed many articles for the press in the UK, Europe and North America, and has often been a guest on BBC Radio 4, notably on The Today Programme, Start the Week, PM and specialist science programmes.

Briefly the youngest tenured academic in the UK. It turned out that the majority of the most famous anecdotes were correct, notably the one in which Dirac, having agreed to answer questions directly after he had given a talk, stood in silence after an audience member said he did not understand an equation that Dirac had written on the blackboard. While researching the book, Graham visited several of the world’s leading centres of research into physics and mathematics, and talked with many top-drawer theoretical physicists, mathematicians and historians of science.

As interested in the arts as he is in the science, he is a keen consumer of theatre, exhibitions, music, film, podcasts and, above all, books. In elegant prose, and using virtually no equations, Farmelo describes the ongoing quest of great thinkers to understand the bedrock nature of reality, from the microworld to the cosmos. Phil Anderson was one of the most creative theoretical physicists of the past century. At first, Graham knew nothing of Dirac’s unusual personality – taciturnity, literal-mindedness, lack of empathy, relatively narrow interests – the source of ‘Dirac stories’. Farmelo Soul Urge, As he says: ‘I want to give some idea of how so many top-class physicists and mathematicians have been led – often to their amazement – to work together. Scientists have long sought a theory that unified our understanding of gravity, which shapes the cosmos, and the three forces mainly responsible for the inner working of atoms. Physicists have discovered that combining quantum mechanics and special relativity leads to a Klondike of new mathematics and a slew of new physical ideas. Formerly an academic, museum professional and undercover restaurant critic, Graham is an award-winning biographer and science writer. Asked what three meals he’d like before facing a firing squad, Graham chose a simple meal in a Tuscan trattoria, a haute cuisine blow-out in Lyon, France, and street-food in Vietnam. In the 1930s, Einstein urged theoreticians to broaden the scope of their most basic laws of nature using a method he believed had played a crucial part in helping him deliver his new theory of gravity. The most popular and elegant theories of what makes the cosmos tick are becoming harder - even impossible - to test directly but Farmelo argues in this tour de force that they’re still taking us deep into the mathematical heart of reality. Paul Adrien Maurice Dirac, OM (August 8, 1902 in Bristol – October 20, 1984 in Tallahassee) was an English physicist.. Dirac's father came from the French-speaking part of Switzerland. An amazing achievement. Even with precious few new clues from sub-atomic experiments, theorists developed new mathematical structures for a candidate unified theory. Read the full review, 'Farmelo shows that theoretical physics and pure mathematics thrive best together.' Perhaps the best reason for believing in the potential of the string framework is that it naturally explains why gravity must exist (by contrast, ordinary field theory cannot be reconciled with the existence of gravity). I don’t see why people find it funny.’. ', 'excellently researched ... and very elegantly written. Showed signs of addiction to Shakespeare, Tolstoy and their successors. Graham wrote of his unreasonable dedication to fine espresso in this piece ‘Shot of Love’ , probably his most-read article. Einstein believed that physicists could build on the mathematical frameworks of their best theories in ‘natural’ ways. Many of these experts commented that physics and mathematics have never been more intertwined, each subject shedding light on the other. In The Strangest Man, Graham Farmelo tries to get under the skin of one Paul Dirac: The man who conjured laws of nature from pure thought. Graham speaks to many audiences on a wide variety of topics, most of them connected with the themes of his books – Dirac, Churchill and his scientists, and the importance of mathematical beauty in theoretical physics. ', 'This masterful book gives us, for the first time, a behind-the-scenes look at how physicists and mathematicians, driven by their pursuit of ultimate Truth, have been drawn into common territory by mysterious intellectual forces seemingly beyond their control. 'Read the full review, 'Entertaining and written with contagious enthusiasm and could almost be described as a page-turner. For several decades, the mathematical approaches proposed by Einstein and Dirac made little or no impact among their peers.
