Number 10 (Story #2), November 27, 1990 by Phillip F. Schewe and Ben Stein AFTER 75 YEARS GENERAL RELATIVITY is still alive and well. Clifford M. Will of Washington University (314-889-6244) reviews the many experimental tests of Albert Einstein's theory, from early measurements of the advance of Mercury's perihelion and the Sun's deflection of starlight, to today's observations of binary pulsars and the search for gravity waves, and finds "GR" to be as valid as ever.
