A Bridge Connecting Classical Physics and Modern Physics

A Classical Physics Review for Nonclassical Physics

‘Reality’ in modern physics

The Copenhagen interpretation According to modern physics, the world is made up from small bits of energy, called ‘quanta’. Each object in the world is a quantum system, made up of individual quanta acting together. In effect, this is like saying that the world and its objects are made up of interacting particles, except that quanta are not quite particles. The trouble is that quanta sometimes ...

Reviews of Modern Physics

* Thesis submitted to Princeton University March 1, 1957 in partial fulfillment of the requirements for the Ph.D. degree. An earlier draft dated January, 1956 was circulated to several physicists whose comments were helpful. Professor Niels Bohr, Dr. H.J.Groenewald, Dr. Aage Peterson, Dr. A.Stern, and Professor L.Rosenfeld are free of any responsibility, but they are warmly thanked for the usef...

Wolfgang Pauli and Modern Physics

In this written version of a pre-dinner-speech at the workshop “The Nature of Gravity” at ISSI I illustrate Pauli’s science primarily with material that has not formally been published by him, but was communicated in detailed letters to eminent colleagues and friends.

Waves in Classical Physics

If I say the word “wave” in no particular context, the image which most probably springs to your mind is one of a roughly periodic undulation on the surface of a pond or, perhaps, the sea. But the concept of a wave in classical physics is actually much more general, and in particular the periodicity is not really an essential aspect. At least in classical (i.e. pre-relativistic as well as pre-q...
