The space-time approach to quantum electrodynamics, as has been developed by
Feynman, seems to offer a very attractive and useful idea to this domain of physics. His …

W e have a habit in writing articles published in scientific journals to make the work as
finished as possible, to cover up all the tracks, to not worry about the blind alleys or to …

In this paper two things are done.(1) It is shown that a considerable simplification can be
attained in writing down matrix elements for complex processes in electrodynamics. Further …

Existing attempts to apply the quantum theory to the electromagnetic field are open to
serious objections. Above all, the time is treated differently from the space co-ordinates; the …

The present paper is the first of a series that seeks to obtain results in agreement with
experience from a completely time-symmetric electromagnetic theory—ie which does not …

Principles of Quantum Electrodynamics concentrates on one of the best understood parts of
quantum field theory, quantum electrodynamics. It emphasizes the physical basis of the …

The box is accurately weighed before and after the shutter has opened in order to determine
the total energy of the particles which have left, and the observer at 0 is provided with means …

Few have done more than Martin Gutzwiller to clarify the connection between classical time-
dependent motion and the time-independent states of quantum systems. Hence it seems …

The letter extends the author's previous considerations on classical radiating electron to
quantum mechanics. As a first approximate step the possibility is considered of introducing …

Kallen's Quantenelektrodynamik provides a concise treatment of the subject. Its strong
points are the careful attention to ex planatory detail, the methodical coverage of all the maj …
