The Strangest Man by Graham Farmelo Pdf

'A monumental achievement - one of the great scientific biographies.' Michael Frayn The Strangest Man is the Costa Biography Award-winning account of Paul Dirac, the famous physicist sometimes called the British Einstein. He was one of the leading pioneers of the greatest revolution in twentieth-century science: quantum mechanics. The youngest theoretician ever to win the Nobel Prize for Physics, he was also pathologically reticent, strangely literal-minded and legendarily unable to communicate or empathize. Through his greatest period of productivity, his postcards home contained only remarks about the weather.Based on a previously undiscovered archive of family papers, Graham Farmelo celebrates Dirac's massive scientific achievement while drawing a compassionate portrait of his life and work. Farmelo shows a man who, while hopelessly socially inept, could manage to love and sustain close friendship.The Strangest Man is an extraordinary and moving human story, as well as a study of one of the most exciting times in scientific history. 'A wonderful book . . . Moving, sometimes comic, sometimes infinitely sad, and goes to the roots of what we mean by truth in science.' Lord Waldegrave, Daily Telegraph

The Principles of Quantum Mechanics by Paul Adrien Maurice Dirac Pdf

The first edition of this work appeared in 1930, and its originality won it immediate recognition as a classic of modern physical theory. The fourth edition has been bought out to meet a continued demand. Some improvements have been made, the main one being the complete rewriting of the chapter on quantum electrodymanics, to bring in electron-pair creation. This makes it suitable as an introduction to recent works on quantum field theories.

Simply Dirac by Helge Kragh Pdf

“What a fantastic entrée into the life of Paul Dirac and the exotic world of Quantum Mechanics, of which he was one of the great pioneers. With its cast of some of the most important scientists of the modern age, this is both an entertaining and an enlightening read.” —Michael White, Bestselling author of 39 books including Isaac Newton: The Last Sorcerer Paul Dirac (1902–1984) was a brilliant mathematician and a 1933 Nobel laureate whose work ranks alongside that of Albert Einstein and Sir Isaac Newton. Although not as well known as his famous contemporaries Werner Heisenberg and Richard Feynman, his influence on the course of physics was immense. His landmark book, The Principles of Quantum Mechanics, introduced that new science to the world and his “Dirac equation” was the first theory to reconcile special relativity and quantum mechanics. Dirac held the Lucasian Chair of Mathematics at Cambridge University, a position also occupied by such luminaries as Isaac Newton and Stephen Hawking. Yet, during his 40-year career as a professor, he had only a few doctoral students due to his peculiar personality, which bordered on the bizarre. Taciturn and introverted, with virtually no social skills, he once turned down a knighthood because he didn’t want to be addressed by his first name. Einstein described him as “balancing on the dizzying path between genius and madness.” In Simply Dirac, author Helge Kragh blends the scientific and the personal and invites the reader to get to know both Dirac the quantum genius and Dirac the social misfit. Featuring cameo appearances by some of the greatest scientists of the 20th century and highlighting the dramatic changes that occurred in the field of physics during Dirac’s lifetime, this fascinating biography is an invaluable introduction to a truly singular man.

Proceedings of the Dirac Centennial Symposium by Howard Baer,Paul Adrien Maurice Dirac,Alexander Belyaev Pdf

Paul Adrian Maurice Dirac (1902-84) is one of the icons of modern physics. His work provided the mathematical foundations of quantum mechanics. He also made key contributions to quantum field theory and quantum statistical mechanics. He is perhaps best known for formulating the Dirac equation, a relativistic wave equation which described the properties of the electron, and also predicted the existence of anti-matter. The Dirac Centennial Symposium commemorated the contributions of Dirac to all areas of physics, and assessed their impact on frontier research. This book constitutes the proceedings of the symposium, containing articles by Leopold Halpern, Pierre Ramond, Frank Wilczek, Maurice Goldhaber, Jonathan Bagger, Joe Lykken, Roman Jackiw, Stanley Deser, Joe Polchinski, Andre Linde and others. A special contribution from Dirac's daughter Monica Dirac presents a portrait of Paul Dirac as father and family man.

A Mathematical Introduction to Dirac's Formalism by S.J.L. van Eijndhoven,J. de Graaf Pdf

This monograph contains a functional analytic introduction to Dirac's formalism. The first part presents some new mathematical notions in the setting of triples of Hilbert spaces, mentioning the concept of Dirac basis. The second part introduces a conceptually new theory of generalized functions, integrating the notions of the first part. The last part of the book is devoted to a mathematical interpretation of the main features of Dirac's formalism. It involves a pairing between distributional bras and kets, continuum expansions and continuum matrices.

Young and Dirac - The Prophets of New Physics by Claus Birkholz Pdf

A critical review of the »Standard« Models. A characteristic of New Physics is its hierarchic organisation in powers of 8 dimensions (Matryoshka principle) and its split into 2 channels. According to Bell, this enables the coexistence of causality with entanglement, shows how visible matter with its non-valence parts condensed out of dark matter, explains the quark confinement and the asymptotic flatness of Eternal Inflation. The world formula unifies all forces of nature to a Grand Unified Theory and this GUT is combined with quantum gravity into a Theory of Everything (ToE). By reproducing the correct value of the fine-structure con-stant, weak interactions are shown to be a dipole effect. A novel segregation between micro- and macrocosm explains the measuring process and the irreversibility of time. It demonstrates the logic gaps in Einstein's General Relativity by quan-tising his curvilinear geometry (including virtual states, dark energy, etc.) thus generating a consistent black-hole physics without singularities. For all that, A. Young and P. Dirac had provided the mathematical basics, while classical physics and Einstein had gone on isolating themselves in self-made deadlocks.

The Dirac Equation by Bernd Thaller Pdf

Ever since its invention in 1929 the Dirac equation has played a fundamental role in various areas of modern physics and mathematics. Its applications are so widespread that a description of all aspects cannot be done with sufficient depth within a single volume. In this book the emphasis is on the role of the Dirac equation in the relativistic quantum mechanics of spin-1/2 particles. We cover the range from the description of a single free particle to the external field problem in quantum electrodynamics. Relativistic quantum mechanics is the historical origin of the Dirac equation and has become a fixed part of the education of theoretical physicists. There are some famous textbooks covering this area. Since the appearance of these standard texts many books (both physical and mathematical) on the non relativistic Schrodinger equation have been published, but only very few on the Dirac equation. I wrote this book because I felt that a modern, comprehensive presentation of Dirac's electron theory satisfying some basic requirements of mathematical rigor was still missing.

Graph Theory in Memory of G.A. Dirac by L. Døvling Andersen,I. Tafteberg Jakobsen,P. Vestergaard,B. Toft,C. Thomassen Pdf

This volume is a tribute to the life and mathematical work of G.A. Dirac (1925-1984). One of the leading graph theorists, he developed methods of great originality and made many fundamental discoveries. The forty-two papers are all concerned with (or related to) Dirac's main lines of research. A number of mathematicians pay tribute to his memory by presenting new results in different areas of graph theory. Among the topics included are paths and cycles, hamiltonian graphs, vertex colouring and critical graphs, graphs and surfaces, edge-colouring, and infinite graphs. Some of the papers were originally presented at a meeting held in Denmark in 1985. Attendance being by invitation only, some 55 mathematicians from 14 countries participated in various lectures and discussions on graph theory related to the work of Dirac. This volume contains contributions from others as well, so should not be regarded only as the proceedings of that meeting. A problems section is included, as well as a listing of Dirac's own publications.

Paul Adrien Maurice Dirac by Behram N. Kursunoglu,Eugene Paul Wigner Pdf

Paul Dirac, who died in 1984, was without question one of the greatest physicists of the twentieth century. His revolutionary contribution to modern quantum theory is remembered for its insight and creativity. He is especially famous for his prediction of the magnetic moment and spin of the electron and for the existence of antiparticles. He was awarded the Nobel Prize for physics in 1933 at the age of 31. In this memorial volume, 24 of Dirac's friends, colleagues and contemporaries remember him with affection. There are chapters describing Dirac's personality, and many anecdotes about the man with a reputation for silence. Other chapters describe Dirac's science and its impact on modern physics.

Dirac Matter by Bertrand Duplantier,Vincent Rivasseau,Jean-Nöel Fuchs Pdf

This fifteenth volume of the Poincare Seminar Series, Dirac Matter, describes the surprising resurgence, as a low-energy effective theory of conducting electrons in many condensed matter systems, including graphene and topological insulators, of the famous equation originally invented by P.A.M. Dirac for relativistic quantum mechanics. In five highly pedagogical articles, as befits their origin in lectures to a broad scientific audience, this book explains why Dirac matters. Highlights include the detailed "Graphene and Relativistic Quantum Physics", written by the experimental pioneer, Philip Kim, and devoted to graphene, a form of carbon crystallized in a two-dimensional hexagonal lattice, from its discovery in 2004-2005 by the future Nobel prize winners Kostya Novoselov and Andre Geim to the so-called relativistic quantum Hall effect; the review entitled "Dirac Fermions in Condensed Matter and Beyond", written by two prominent theoreticians, Mark Goerbig and Gilles Montambaux, who consider many other materials than graphene, collectively known as "Dirac matter", and offer a thorough description of the merging transition of Dirac cones that occurs in the energy spectrum, in various experiments involving stretching of the microscopic hexagonal lattice; the third contribution, entitled "Quantum Transport in Graphene: Impurity Scattering as a Probe of the Dirac Spectrum", given by Hélène Bouchiat, a leading experimentalist in mesoscopic physics, with Sophie Guéron and Chuan Li, shows how measuring electrical transport, in particular magneto-transport in real graphene devices - contaminated by impurities and hence exhibiting a diffusive regime - allows one to deeply probe the Dirac nature of electrons. The last two contributions focus on topological insulators; in the authoritative "Experimental Signatures of Topological Insulators", Laurent Lévy reviews recent experimental progress in the physics of mercury-telluride samples under strain, which demonstrates that the surface of a three-dimensional topological insulator hosts a two-dimensional massless Dirac metal; the illuminating final contribution by David Carpentier, entitled "Topology of Bands in Solids: From Insulators to Dirac Matter", provides a geometric description of Bloch wave functions in terms of Berry phases and parallel transport, and of their topological classification in terms of invariants such as Chern numbers, and ends with a perspective on three-dimensional semi-metals as described by the Weyl equation. This book will be of broad general interest to physicists, mathematicians, and historians of science.
