OPERATIONALISM IN RELATIVITY

Aspects of ''operationalism'' are presented as applied to coordinates in special and general relativity. In this context Einstein's equivale nce principle is discussed as it applies to operational gedanken (thou ght) experiments. A comparison is shown in the approach of Einstein an d others to the fundamental metric of general relativity. A ''relaxed' ' interpretation of the term ''operational'' is given, and examples of such operational methods are shown.
