a . i a ee Ab raham Pais a Author of Subtle is the Lori = The Science & the Life of Albert Einstein 7 Ss 3 \ me); SCIENCE A portrait gallery of — twentieth-century physicists — SS SESS Abraham Pais is the acclaimed author of the definitive biographies of Albert Einstein and Niels Bohr, two of the twentieth century's greatest scientists. As a distinguished theoretical physicist himself, he was also acquainted with many of the other great scientists. In this new book, Pais turns his attention to seventeen other scientists, all distinguished in their own right, but who had appeared as the supporting cast to his previous biographies. We meet, among others, the famously taciturn Paul Dirac; Max Born, who coined the term ‘quantum mechanics’; Wolfgang Pauli, famed for his exclusion ptinciple and known as the conscience of twentieth- century physics; Mitchell Feigenbaum, inventor of chaos theory; and John yon Neumann, one of the most influential mathematicians of the century. In addition, and because their work is so relevant to the others discussed, Pais has included chapters on Einstein and Bohr, giving the essence of their character and scientific achievement. In each case, Pais presents a blend of the personality and achievements of the scientist, assisted by his deep knowledge of physics and his personal acquaintance with the subject. The result is a unique and illuminating collection of portraits that shed light on both the personalities and the development of science of this group of great scientists. It will be read by all those with an interest in the development of science in the twentieth century, from relativity to chaos theory.
