Popis:	It is shown that when time is measured in a Schwarzschild field by radially falling or rising geodesic clocks, the usual Schwarzschild radial coordinate R, defined by ds/sup 2/ = dR/sup 2//(1 - 2M/R) - (1 - 2M/R) dT/sup 2/ + R/sup 2/d..cap omega../sup 2/, has the physical significance that it is a measure of proper distance between two events that occur simultaneously relative to the radially moving geodesic clocks, the two events lying on the same radial coordinate line.
