By the same token, and so as to avoid the impression that I attempted a comprehensive learned survey of the field, I shall refrain from quoting any references.

,Comments on ‘Causality Requirements and the Theory of Relativity’,Perhaps the most important point made in Havas’ paper is his emphasis on the need for theoretical physics to come to terms with the full implications of the theory of relativity; and, indeed, to achieve a much better understanding of just what those implications are.

Causality Requirements and the Theory of Relativity,sense, we shall be concerned here with three theories of relativity, the one associated with Newtonian physics, and Einstein’s special and general theory. The groups to be considered are those associated with transformations of the space-time coordinates, and thus the physics underlying them is that
