In this collection of informal reminiscences, first published in 1975, Max Born has written an extraordinarily vivid account of his life and work, originally intended for his family. Ranging from his time at the University of Göttingen, where Born had his first real motivation for a professional career in science, to the period in Berlin as professor extraordinary, when he and his wife became close friends of Einstein, these anecdotes and memories chart the "heroic age of physics" from the perspective of one of its leading characters. In 1954 Born was awarded the Nobel Prize in physics for his fundamental contributions to the great discovery of that cadre of superlative scientific minds - quantum theory. But his scientific research provides only one strand of this story. Born's varied interests outside science led to many interesting experiences - some of historical importance insofar as they offer a glimpse into German society before and between the wars.

Analogies play a fundamental role in science. To understand how and why, at a given moment, a certain analogy was used, one has to know the specific, historical circumstances under which the new idea was developed. This historical background is never presented in scientific articles and quite rarely in books. For the general reader, the undergraduate or graduate student who learns the subject for the first time, but also for the practitioner who looks for inspiration or who wants to understand what his colleague working in another field does, these historical circumstances can be fascinating and useful. This book discusses a series of analogy effects in subatomic physics, the prediction and theory of which the author has contributed to in the last 50 years. These phenomena are presented at a level accessible to the non-specialist, without formulae but with emphasis on the personal and historical background: memoirs of meetings, discussions and correspondence with collaborators and colleagues. As such, besides its scientific aspects, the book constitutes an absorbing witness account of a holocaust survivor who subsequently illegally crossed the Iron Curtain to escape communist persecution.

A portrait of the twentieth-century scientific community and a memoir of the scientist who was at the forefront of particle physics.
