Freeman Dyson – författare

The Pleasure of Finding Things Out is a magnificent treasury of the best short works of Richard P. Feynman,from interviews and speeches to lectures and printed articles. A sweeping, wide-ranging collection, it presents an intimate and fascinating view of a life in science-a life like no other. From his ruminations on science in our culture to his Nobel Prize acceptance speech, this book will fascinate anyone interested in the world of ideas.

Spanning the years from World War II, when he was a civilian statistician in the operations research section of the Royal Air Force Bomber Command, through his studies with Hans Bethe at Cornell University, his early friendship with Richard Feynman, and his postgraduate work with J. Robert Oppenheimer, Freeman Dyson has composed an autobiography unlike any other. Dyson evocatively conveys the thrill of a deep engagement with the world-be it as scientist, citizen, student, or parent. Detailing a unique career not limited to his ground-breaking work in physics, Dyson discusses his interest in minimizing loss of life in war, in disarmament, and even in thought experiments on the expansion of our frontiers into the galaxies.

Readers of Freeman Dyson’s previous books, Disturbing the Universe, Weapons and Hope, and Infinite in All Directions, have discovered for themselves what Dyson reveals here: that he was a writer long before he became a distinguished scientist. The aim of this new book, as Dyson says, is to open windows, to let the experts inside the temple of science see out, and to let the ordinary citizens outside see in.” In this process an immensely broad range of ideas, people, contemporary history, and discoveries of many sorts pass in review. Beginning with a piece of writing he did as a child and ending with recent work, he goes from Eros, the god or youthful passion, to Gaia, the fertile life-giving mother-planet Earth. The pilgrimage is a good metaphor for the life of a writer. This book is full of discoveries. In the company of one of the most lucid minds of our time, one approaches great men and problems central to our common existence. Always there is warmth, kindness, high intelligence and humor. Dyson is intimate with both science and man. Whether he is dealing with the problems of physics or politics, whether he is engrossed in astronomy or literature, whether he is concentrating on an African village of space science, Dyson’s view is always “infinite in all directions,” always following the path of diversity, always keeping his eye on the wonder of our earth and the health and happiness of its inhabitants.

How did life on earth originate? Did replication or metabolism come first in the history of life? In this book, Freeman Dyson examines these questions and discusses the two main theories that try to explain how naturally occurring chemicals could organize themselves into living creatures. The majority view is that life began with replicating molecules, the precursors of modern genes. The minority belief is that random populations of molecules evolved metabolic activities before exact replication existed. Dyson analyzes both of these theories with reference to recent important discoveries by geologists and chemists. His main aim is to stimulate experiments that could help to decide which theory is correct. This second edition covers the enormous advances that have been made in biology and geology in the past and the impact they have had on our ideas about how life began. It is a clearly-written, fascinating book that will appeal to anyone interested in the origins of life.

Imagine a world where whole epochs will pass, cultures rise and fall, between a telephone call and the reply. Think of the human race multiplying 500-million fold, or evolving new, distinct species. Consider the technology of space colonization, computer-assisted reproduction, the “Martian potato.” One hundred years after H. G. Wells visited the future in The Time Machine, Freeman Dyson marshals his uncommon gifts as a scientist and storyteller to take us once more to that ever-closer, ever-receding time to come.Since Disturbing the Universe, the book that first brought him international renown, Freeman Dyson has been helping us see ourselves and our world from a scientist’s point of view. In Imagined Worlds he brings this perspective to a speculative future to show us where science and technology, real and imagined, may be taking us. The stories he tells—about “Napoleonic” versus “Tolstoyan” styles of doing science; the coming era of radioneurology and radiotelepathy; the works of writers from Aldous Huxley to Michael Crichton to William Blake; Samuel Gompers and the American labor movement—come from science, science fiction, and history. Sharing in the joy and gloom of these sources, Dyson seeks out the lessons we must learn from all three if we are to understand our future and guide it in hopeful directions.Whether looking at the Gaia theory or the future of nuclear weapons, science fiction or the dangers of “science worship,” seagoing kayaks or the Pluto Express, Dyson is concerned with ethics, with how we might mitigate the evil consequences of technology and enhance the good. At the heart of it all is the belief once expressed by the biologist J. B. S. Haldane, that progress in science will bring enormous confusion and misery to humankind unless it is accompanied by progress in ethics.

Having penned hundreds of letters to his family over four decades, Freeman Dyson has framed them with the reflections made by a man now in his nineties. While maintaining that “the letters record the daily life of an ordinary scientist doing ordinary work,” Dyson nonetheless has worked with many of the twentieth century’s most renowned physicists, mathematicians, and intellectuals, so that Maker of Patterns presents not only his personal story but chronicles through firsthand accounts an exciting era of twentieth-century science.Though begun in the dark year of 1941 when Hitler’s armies had already conquered much of Europe, Dyson’s letters to his parents, written at Trinity College, Cambridge, often burst with the curiosity of a precocious seventeen-year-old. Pursuing mathematics and physics with a cast of legendary professors, Dyson thrived in Cambridge’s intellectual ferment, working on, for example, the theory of partitions or reading about Kurt Gödel’s hypotheses, while still finding time for billiards and mountain climbing. After graduating and serving with the Royal Air Force’s Bomber Command operational research section, whose job it was “to demolish German cities and kill as many German civilians as possible,” Dyson visited a war-torn Germany, hoping through his experience to create a “tolerably peaceful world.”Juxtaposing descriptions of scientific breakthroughs with concerns for mankind’s future, Dyson’s postwar letters reflect the quandaries faced by an entire scientific generation that was dealing with the aftereffects of nuclear detonations and concentration camp killings. Arriving in America in 1947 to study with Cornell’s Hans Bethe, Dyson continued to send weekly missives to England that were never technical but written with grace and candor, creating a portrait of a generation that was eager, as Einstein once stated, to solve “deep mysteries that Nature intend[ed] to keep for herself.”We meet, among others, scientists like Richard Feynman, who took Dyson across country on Route 66, Robert Oppenheimer, Eugene Wigner, Niels Bohr, James Watson, and a young Stephen Hawking; and we encounter intellectuals and leaders, among them Reinhold Niebuhr, George Kennan, Arthur C. Clarke, as well as Martin Luther King, Jr.The “patterns of comparable beauty in the dance of electrons jumping around atoms” invariably replicate themselves in this autobiography told through letters, one that combines accounts of wanton arms development with the not-inconsiderable demands of raising six children. As we once again attempt to guide society toward a more hopeful future, these letters, with their reenactment of what, at first, seems like a distant past, reveal invaluable truths about human nature.

Written between 1940 and the late 1970s, the postwar recollections of renowned physicist Freeman Dyson have been celebrated as an historic portrait of modern science and its greatest players, including Robert Oppenheimer, Richard Feynman, Stephen Hawking, and Hans Bethe. Chronicling the stories of those who were engaged in solving some of the most challenging quandaries of twentieth-century physics, Dyson lends acute insight and profound observations to a life’s work spent chasing what Einstein called those “deep mysteries that Nature intends to keep for herself.” Whether reflecting on the drama of World War II, the moral dilemmas of nuclear development, the challenges of the space program, or the demands of raising six children, Dyson’s annotated letters reveal the voice of one “more creative than almost anyone else of his generation” (Kip Thorne). An illuminating work in these trying times, Maker of Patterns is an eyewitness account of the scientific discoveries that define our modern age.

Die berühmte Vorlesung von Freeman Dyson - nun erstmals auf Deutsch. In den 1940er Jahren zeigte Freeman Dyson die Äquivalenz zwischen den beiden Formulierungen der QED - des Pfadintegralansatzes von Richard Feynman und der Variationsmethoden von Julian Schwinger - und bewies somit die Konsistenz der QED. Dieses Buch beinhaltet die wertvollen - nie zuvor auf Deutsch publizierten - Vorlesungen über Quantenfeldtheorie, die Dyson an der Cornell Universität 1951 gehalten hat. Der Theoretiker Edwin Thompson Jaynes bemerkte dazu: "Für eine Generation von Physikern waren diese Vorlesungen ein Gewinn: klarer und besser motiviert als Feynmans Vorlesungen, und schneller und kompakter als Schwingers." Zukünftige Leser werden diese Vorlesungen ebenfalls mit großem Genuss lesen und von dem klaren Stil profitieren, der für Dyson stets so charakteristisch gewesen ist.Aus dem Inhaltsverzeichnis: 1 - Die Diracgleichung, 2 - Streuprobleme und die Born-Approximation, 3 - Die klassische und quantenmechanische Feldtheorie, 4 - Beispiele quantisierter Feldtheorien (Maxwellfeld, Diracelektronen), 5 - Streuprobleme freier Teilchen (Paar Annihilation, Möller-Streuung, Klein-Nishina-Formel), 6 - Allgemeine Theorie der Streuung (Feynman-Graphen, Infrarotkatastrophe), 7 - Streuung an einem statischen Potenzial und experimentelle Ergebnisse.

Renowned physicist and mathematician Freeman Dyson is famous for his work in quantum mechanics, nuclear weapons policy and bold visions for the future of humanity. In the 1940s, he was responsible for demonstrating the equivalence of the two formulations of quantum electrodynamics — Richard Feynman's diagrammatic path integral formulation and the variational methods developed by Julian Schwinger and Sin-Itiro Tomonoga — showing the mathematical consistency of QED.This invaluable volume comprises the legendary lectures on quantum electrodynamics first given by Dyson at Cornell University in 1951. The late theorist Edwin Thompson Jaynes once remarked, “For a generation of physicists they were the happy medium: clearer and better motivated than Feynman, and getting to the point faster than Schwinger”.This edition has been printed on the 60th anniversary of the Cornell lectures, and includes a foreword by science historian David Kaiser, as well as notes from Dyson's lectures at the Les Houches Summer School of Theoretical Physics in 1954. The Les Houches lectures, described as a supplement to the original Cornell notes, provide a more detailed look at field theory, a careful and rigorous derivation of Fermi's Golden Rule, and a masterful treatment of renormalization and Ward's Identity.Future generations of physicists are bound to read these lectures with pleasure, benefiting from the lucid style that is so characteristic of Dyson's exposition.
