The Evolution of Physics: The Growth of Ideas From Early Concepts to Relativity and Quanta is a science book for the lay reader, by Albert Einstein and Leopold Infeld, tracing the development of ideas in physics. It was originally published in 1938 by Cambridge University Press. It was a popular success,[1] and was featured in a Time magazine cover story. In addition to its contribution to physics as a discipline, this book presents an outstanding reflection on the power of ideas and imagination in scientific inquiry.[2]

Background of collaboration

Einstein agreed to write the book partly as a way to help Infeld financially.[3] Infeld collaborated briefly in Cambridge with Max Born, before moving to Princeton, where he worked with Einstein at the Institute for Advanced Study. Einstein tried to get Infeld a permanent position there, but failed.[4] Infeld came up with a plan to write a history of physics with Einstein, which was sure to be successful, and split the royalties. When he went to Einstein to pitch the idea, Infeld became incredibly tongue-tied, but he was finally able to stammer out his proposal. “This is not at all a stupid idea,” Einstein said. "Not stupid at all. We shall do it." The book was published by Simon & Schuster.

Book's point of view

In the book, Einstein pushed his realist approach to physics in defiance of much of quantum mechanics. Belief in an “objective reality,” the book argued, had led to great scientific advances throughout the ages, thus proving that it was a useful concept even if not provable. “Without the belief that it is possible to grasp reality with our theoretical constructions, without the belief in the inner harmony of our world, there could be no science,” the book declared. “This belief is and always will remain the fundamental motive for all scientific creation.”

In addition, Einstein used the text to defend the utility of field theories amid the advances of quantum mechanics. The best way to do that was to view particles not as independent objects but as a special manifestation of the field itself: "Could we not reject the concept of matter and build a pure field physics? We could regard matter as the regions in space where the field is extremely strong. A thrown stone is, from this point of view, a changing field in which the states of the greatest field intensity travel through space with the velocity of the stone."[5]

Contents

The book has four chapters: The Rise of The Mechanical View; The Decline of the Mechanical View; Field, Relativity; and Quanta.

The third chapter (Field, Relativity) examines lines of force starting with gravitational fields (i.e., a physical collection of forces), moving on to descriptions of electric and magnetic fields. The authors explain that they are attempting to "translate familiar facts from the language of fluids...into the new language of fields." They state that the Faraday, Maxwell, and Hertz experiments led to modern physics. They describe how "The change of an electric field produced by the motion of a charge is always accompanied by a magnetic field."
