Werner Heisenberg Livres

"La science est faite par les hommes. Ce fait, évident en soi, est facilement oublié ; il est peut-être utile de le rappeler." Dans sa fascinante autobiographie intellectuelle, Werner Heisenberg, l'un des plus grands scientifiques du XXe siècle, tenace au fil de conversations retrouvées l'évolution de la physique telle qu'il l'a vécue, depuis ses premiers contacts avec la théorie atomique (1919-1920) jusqu'aux découvertes de nouvelles particules élémentaires (1961-1963). On y croisera Wolfgang Pauli en randonnée dans les Alpes bavaroises, Niels Bohr en pleins travaux, des discussions avec Einstein... Né en Allemagne, Heisenberg n'a pas quitté le pays pendant la Seconde Guerre mondiale. Ces pages offrent également un témoignage précieux sur la vie universitaire dans l'Allemagne nazie, la situation des physiciens juif s, contraints d'émigrer, l'incertitude des autres, leur désarroi, et l'atmosphère même de l'Université allemande en ces armées sombres. Ecrits de manière simple et vivante, ces chapitres forment une extraordinaire introduction aux grands problèmes scientifiques de notre siècle, et un livre d'histoire passionnant.

Resté inédit jusqu'en 1984, ce manuscrit se présentait initialement sans titre ni date. Il semble que Heisenberg l'ait seulement distribué, aussitôt terminé (vers Noël 1942), à quelques proches et sous le sceau du secret, en raison des critiques ouvertes qu'il contenait à l'encontre du régime nazi. A cette époque, Heisenberg est engagé dans un travail fondamental dans le domaine de la théorie des particules élémentaires et il participe au programme atomique allemand. Il est aussi impliqué, depuis 1933, dans une lutte violente avec certains idéologues du régime nazi, que lui valent ses prises de position publiques en faveur de la "physique juive". Toutefois, comme on le verra, cet arrière-plan particulièrement sombre et tendu ne fait que rendre d'autant plus admirable la sérénité, la netteté et la concision avec lesquelles Heisenberg expose ici sa philosophie, et la nouvelle "position à l'égard de la réalité" qu'induisent les sciences contemporaines.

Personal letters reveal the quandary of a prominent German physicist during the Nazi years and the strength he shared with his loving wife Nobel Prize-winning physicist Werner Heisenberg lived far from his wife, Elisabeth, during most of the Second World War. An eminent scientist, Werner headed Germany's national atomic research project in Berlin, while Elisabeth and their children lived more safely in Bavaria. This selection of more than 300 letters exchanged between husband and wife reveals the precarious nature of Werner's position in the Third Reich, Elisabeth's increasingly difficult everyday life as the war progressed, and the devoted relationship that gave strength to them both. These letters provide a fascinating new perspective on Werner's much-debated wartime work and his attitude toward the atomic bomb. They also shed light on his reluctance to emigrate despite the urging of friends. An excerpt from his private diary, an introduction and notes by his daughter, and a selection of personal family photographs complete this compelling volume.

Exploring the intersection of philosophy and science, this text delves into Heisenberg's reflections on the nature of reality and the implications of quantum mechanics. As a prominent figure in 20th-century science, Heisenberg articulates his thoughts on how our understanding of the physical world shapes our perception of reality. This English translation offers readers a unique opportunity to engage with his groundbreaking ideas and the philosophical questions they raise, making it an essential read for those interested in science and philosophy.

In nine essays and lectures composed in the last years of his life, Werner Heisenberg offers a bold appraisal of the scientific method in the twentieth century--and relates its philosophical impact on contemporary society and science to the particulars of molecular biology, astrophysics, and related disciplines. Are the problems we define and pursue freely chosen according to our conscious interests? Or does the historical process itself determine which phenomena merit examination at any one time? Heisenberg discusses these issues in the most far-ranging philosophical terms, while illustrating them with specific examples.

Nobel Laureate discusses quantum theory, uncertainty, wave mechanics, work of Dirac, Schroedinger, Compton, Einstein, others. "An authoritative statement of Heisenberg's views on this aspect of the quantum theory." ? Nature.

The seminal work by one of the most important thinkers of the twentieth century, Physics and Philosophy is Werner Heisenberg's concise and accessible narrative of the revolution in modern physics, in which he played a towering role. The outgrowth of a celebrated lecture series, this book remains as relevant, provocative, and fascinating as when it was first published in 1958. A brilliant scientist whose ideas altered our perception of the universe, Heisenberg is considered the father of quantum physics; he is most famous for the Uncertainty Principle, which states that quantum particles do not occupy a fixed, measurable position. His contributions remain a cornerstone of contemporary physics theory and application.
