Freeman Dyson était un physicien et pédagogue célébré pour ses explorations spéculatives sur les civilisations extraterrestres et ses contributions significatives à l'électrodynamique quantique, à la physique du solide, à l'astronomie et au génie nucléaire. Il a proposé plusieurs concepts influents portant son nom, dont la transformation de Dyson, l'arbre de Dyson, la série de Dyson et la sphère de Dyson. Fils de musicien, la passion précoce de Dyson pour les mathématiques s'est épanouie à l'Université de Cambridge. Ses profondes intuitions en physique théorique et en cosmologie se sont mêlées à une perspective visionnaire sur l'avenir de l'humanité parmi les étoiles.
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. This volume comprises the lectures on quantum electrodynamics first given by Dyson at Cornell University in 1951.
Focuses on the myriad ways in which the universe presents itself to us - and how, as observers and participants in its processes, we respond to it. Taken from the author's public lectures, this book begins with a consideration of the practical and political questions surrounding biotechnology.

This book is a sequel to the volume of selected papers of Dyson up to 1990 that was published by the American Mathematical Society in 1996. The present edition comprises a collection of the most interesting writings of Freeman Dyson, all personally selected by the author, from the period 1990 - 2014.The five sections start off with an Introduction, followed by Talks about Science, Memoirs, Politics and History, and some Technical Papers. The most noteworthy is a lecture entitled Birds and Frogs to the American Mathematical Society that describes two kinds of mathematicians with examples from real life. Other invaluable contributions include an important tribute to C. N. Yang written for his retirement banquet at Stony Brook University, as well as a historical account of the Operational Research at RAF Bomber Command in World War II provocatively titled A Failure of Intelligence. The final section carries the open-ended question of whether any conceivable experiment could detect single gravitons to provide direct evidence of the quantization of gravity -- Is a Graviton Detectable? Various possible graviton-detectors are examined.This invaluable compilation contains unpublished lectures, and surveys many topics in science, mathematics, history and politics, in which Freeman Dyson has been so active and well respected around the world.
The physicist explores a wide range of subjects, from biological existence and nuclear weapons, to ethics, politics, and the exploration of space and how all these things fit in the grand scheme of the universe.
Dyson "celebrates openness to unconventional ideas and the spirit of joyful dreaming in which he believes that science should be pursued. Throughout these essays, which range from the creation of the Royal Society in the seventeenth century to the scientific inquiries of the Romantic generation to recent books by Daniel Kahneman and Malcolm Gladwell, he seeks to break down the barriers that separate science from other sources of human wisdom"--Amazon.com.
How did life on earth originate? Did replication or metabolism come first in the history of life? In this updated and expanded second edition of Origins of Life, 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.
Exploring the rebellious spirit of scientists throughout history, Freeman Dyson emphasizes the blend of imagination and reason in scientific discovery. He shares captivating stories of notable figures like Newton and Einstein, while reflecting on their unique contributions and personal quirks. Dyson critiques modern scientific trends and speculates on future challenges in climate prediction and space colonization. Additionally, he delves into philosophical issues surrounding ethics, the environment, and the intersection of science and religion, providing a rich tapestry of insights into the scientific endeavor.
A lifetime of candid reflections from physicist Freeman Dyson, “an acute observer of personality and human foibles” (New York Times Book Review). 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.
Wie kommen neue Forschungsprogramme zustande? Welchen Stellenwert haben dabei technologische Innovationen? Welche Rolle spielen diese Innovationen für Wirtschaft und Gesellschaft? Und welche Rolle werden bestimmte Leittechnologien im neuen Jahrhundert spielen? Diesen Fragen geht der Autor nach - nicht mit einer großen Theorie im Hintergrund, sondern in der zwangslosen Form von instruktiven Beispielen aus Biologie, Physik, Astronomie und Technik.
