The relativistic quantum theory of fields was born some thirty-five years ago through the
paternal efforts of Dirac, Heisenberg, Pauli and others. It was a somewhat retarded …

HE principal theme of this discourse is the great difference between the relation of special
relativ-ity and quantum theory on the one hand, and general relativity and quantum theory …

General relativity's basic observable quantities are space-time distances between events,
the events being, at least in principle, crossing points of the world-lines of two objects, one of …

In contrast to non-relativistic quantum mechanics, which can be considered logically
complete, we possess today only fragments of a relativistic quantum mechanics. We shall …

The working out of the implications of the quantum theory and the theory of relativity, and the
study of their impact on each other, has been the major preoccupation of theoretical physics …

Nonrelativistic Quantum Mechanics (2) Relativistic Quantum field Theory (3) Exercises and …

Let me begin by recalling the way I learned about Dirac's relativistic equation of the electron.
It was from a letter to Max Born who asked Dirac to review an article by a third person. The …

The end of the first half of the century coincided with a notable incision in the search for
fundamental laws. The breakthrough in the handling of quantum electrodynamics had …

The articles collected in this volume were written for a Colloquium on Fifty Years of Quantum
Mechanics which was held at the University Louis Pasteur of Strasbourg on May 2-4, 1974 …
