Published in 1934, this monograph was one of the first introductory accounts of the principles which form the physical basis of the Quantum Theory, considered as a branch of mathematics. The exposition is restricted to a discussion of general principles and does not attempt detailed application to the wide domain of atomic physics, although a number of special problems are considered in elucidation of the principles. The necessary fundamental mathematical methods – the theory of linear operators and of matrics – are developed in the first chapter so this could introduce anyone to the new theory. This is an interesting snapshot of scientific history.
Preface 1. The Theory of Linear Operators 2. The Laws of Measurement in Atomic Physics 3. The Exchange Relations and the Equations of Motion 4. The Spin Operators 5. Composite Systems
Reissuing works originally published between 1921 and 1988, this set offers a selection of scholarship covering historical developments in scientific thinking. Volumes range from Einstein's theories to quantum theory and genetics making this a comprehensive collection of previously out-of-print works. Many of the works review scientific advances in general or science and philosophy at the time; a great insight into the intellectual world of the 20th Century.
