First published in 1956 The Language of Modern Physics gives a complete account of the concepts both of classical and quantum physics. The first part of the book deals with modern logic and semantics and discussion is based on the semantic conception of truth and leads up to the criterion of meaning. The second and main part of the book is about basic ideas of physics. Here the model which underlies a scientific theory is of greatest import; in most instances the model is tacitly assumed, but we must bring it into the open if we want to understand the theory. The third and last part deals with the methods scientists use for confirming their hypotheses. This book is a must read for students and scholars of philosophy of science and philosophy in general.
