There are two types of books on physics. One is the textbook, intended for teaching the reader the facts and theories of physics. Books of this kind usually omit all historical aspects of the development of science; the only information concerning great scientists of the past and present is limited to the year of birth and death (or ---) given in brackets after the name. The other type is essentially historical, devoted to biographical data and to other character analysis of the great men of science, and simply listing their discoveries under the assumption that the reader, studying the history of a given science, is familiar with that science himself.Reading the last paragraph above, one might think that Biography of Physics gives equal numbers of pages to biographies of physicists and to explaining how physics works. This isn't correct; the personal information about physicists is mostly short anecdotes in between much longer explanations of physical experiments and principles. What's really important here is the experiments -- this is a book about how physics was developed: what ideas people started with, what kinds of experiments they did to test them, how they explained the results of the experiments.
In the present book I have tried to keep a midway course, discussing on an equal basis the trial of Galileo and the basic laws of mechanics which he discovered, or giving my personal recollections about Niehls Bohr along with detailed discussion of Bohr's atomic model. The discussion in each of the eight chapters is centered around a single great figure, or at most two, with other physicists of that era and their contributions forming more of the background. This accounts for the omission of many names which would be found in most books on the history of physics, and for the omission of many topics that are a "must" in the regular physics textbooks. The aim of this book is to give the reader the feeling of what physics is, and what kinds of people physicists are, thus getting him interested enough to pursue his studies by seeking out more systematically written books on the subject.
