Reminiscing with Werner Heisenberg about the evolution of quantum mechanics

This book is a collection of nine essays/lectures delivered by Werner Heisenberg in the last few years of his illustrious career in the contribution to the understanding of physical reality. This group of essays deals, briefly, with the historical development of quantum mechanics, and how the concept of matter as a particle was replaced by energy and by fundamental symmetry. These essays not only touch of upon one of the most fundamental aspects of physical reality but also some of the most private moments in the lives of the founding fathers of modern physics. The title of the book "Encounters with Einstein" is somewhat misleading since only one essay (chapter 7) deals with this subject and this chapter has the same title as the book. Heisenberg was a student of Sommerfeld at Munich who was a close friend of Einstein and a supporter of theory of relativity who use to share Einstein's letters with his students, and discuss the physics written in these letters. Heisenberg describes his interest in meeting Einstein as he started working in the developing field of quantum physics. This was during 1920s when quantum mechanics was beginning to take shape. It was also the time when the Third Reich was gaining momentum and anti-Semitism was soaring in Germany. Einstein was most respected in the academic world and obviously he was the target of nationalists. At the 1922 congress of German scientists held at the Leipzig, the students of one of the most respected association of German Experimental Physicists distributed red leaflets suggesting "that the theory of relativity is totally unproved Jewish speculation, and that it had been undeservedly played up through the puffery of Jewish newspapers on behalf of Einstein, a fellow member of the race." Heisenberg recalls this as the poisoning of science by political passions. It is ironic if we recall that Islamic countries and Islamists brand 9/11 terrorist attack to Jews and Israel: This is certainly very saddening. According to one of the Einstein's work; the requirement that a physical theory should only contain quantities that can be directly observed will guarantee a connection between the mathematical formalism and the phenomena. In one of his discussion with Einstein, Heisenberg argued that the path of the electron within an atom must be abandoned from the theory because no such path is experimentally observed except for the light frequencies radiated by the atom, intensities and transition probabilities. Heisenberg stated that he was astonished to see that Einstein did not agree with him and in fact argued that the theory in fact also contains unobservable quantities. When Heisenberg pointed out that Einstein had made a similar assumption (existence of only observable quantities) in the special theory of relativity, he responded simply by stating; "Perhaps I did use such philosophy earlier, and also wrote it, but it is nonsense all the same." Einstein had revised his philosophical outlook. His vis

Excellent book

This is one of the most fluent book written over modern physics even for the non-physicist. His ideas on scientific tradition and scientific prejudice is quite striking. Definitely recommended. This is one book which I wished to be thicker...

Essays from Heisenberg's Later Years, 1972-1975

These essays were first published by Seabury Press in 1983 under the title Tradition in Science. A new edition, titled Encounters with Einstein And Other Essays on People, Places, and Particles, was published in 1989 by Princeton University Press.Throughout his life Werner Heisenberg shared his enthusiasm for physics and philosophy, frequently giving presentations to general audiences. Several essays address the history of quantum physics. Others are more technical and include topics like cosmic radiation, particle physics, and closed-theories in physics. All essays are well-crafted and should be accessible to a wide audience.Heisenberg only met Einstein on a few occasions. The title essay, Encounters with Einstein, describes these encounters, including a final meeting at Princeton a few months before Einstein's death. While he admitted that he had never discussed politics with Einstein, Heisenberg did comment on Einstein's pacifism. Heisenberg does not discuss his own beliefs, nor his role in WWII Germany.At several points in this collection Heisenberg expresses his concerns with the theoretical direction that particle physics was taking in the early 1970s. In his essay "What is an Elementary Particle?", he expresses his doubts regarding quark theory. It was interesting to see Heisenberg in one essay lamenting Einstein's reluctance to accept quantum theory while elsewhere he himself was having difficulty with quark theory.I highly recommend these essays for any reader wishing to become more acquainted with Heisenberg. Also, as a follow-up I suggest reading Philosophical Problems of Quantum Physics, a collection of Heisenberg's lectures that span 1932-1948. The more persistent reader might be interested in Physics and Philosophy: The Revolution in Modern Science. This work by Heisenberg is more philosophical and requires careful reading. This volume benefits from a lengthy and scholarly overview by F. S. C. Northrop, Sterling Professor of Philosophy and Law, Yale University.

The retrospective of a man with a two-sided past

This book reminds me a great deal of, "A Mathematician's Apology" by Hardy. Like Hardy, Heisenberg is in his last years, and knows that his productive ones are behind him. Therefore, he puts forward a series of essays and lectures that are a retrospective of his activity in physics as well as some philosophical thoughts concerning where he believes it is going. Heisenberg was a Nobel prize winner and the first enunciator of the uncertainty principle that bears his name. For these reasons, his thoughts on some of the consequences of the principle are well worth reading. However, Heisenberg is also known for other, more dark reasons. He was the director of the German atomic projects in World War II and seemed to have little difficulty in working under the Nazi tyranny while many of his colleagues were hounded and executed. He also proved to be an effective survivor, becoming the head of the Max Planck Institute of Physics in West Germany after the war. This involvement with the Nazis makes the chapter "Encounters and Conversations with Albert Einstein" fascinating reading. From it, you would not know about his record of collaboration with the regime that tried to exterminate Einstein and his ideas. One must read that chapter very carefully and do a great deal of reading between the lines to really understand what is being said. The fact that Einstein was willing to meet with Heisenberg after the war tells a lot more about Einstein that it does about Heisenberg. This book is interesting as much for what is not said as it is for what is said. This was an opportunity for Heisenberg to say something about his involvement in some very bad things as well as to put forward thoughts about physics. The first was missed and the second was a hit. If you are interested in some thoughts about how physics has evolved this century from one of best practitioners, then this is a book that will interest you.

Insight and inspiration

This is an excellent bedside book for anyone interested in the development of quantum mechanics by one of its primary discoverers. This small book of short essays provides insight into the life and personality of one of the greatest (and most enigmatic) physicists of the 20th century. This is not a technical book, nor is it an introduction to (or explaination of) quantum theory. Rather, each essay provides a unique sidebar on a variety of topics to which WH has either contributed directly or considered in detail. Heisenberg is a lucid and concise writer of remarkable insight.
