Tel Aviv I.J; . -Acknowl edges Rehovot's Role,
ti ming - Einstein Theory on Gravity

TEL AVIV (JTA) — Tel Aviv
University and the. Weizmann In-
stitute o# ;science in Rehovot have
agreed to share credit for i series
of, scientific , experiments, which
purportedly confirm Einstein's
theory that gravity acts in waves.
The agreement followed a con-
ciliatory meeting between the
heads of the two institutions. The
Weizmann Institute had objected
to Tel Aviv University taking sole
credit for the discovery.
The experiments were success-
fully conducted by Prof. Dror
Sadeh of Tel Aviv University's
department of physics and astro-
nomy.
Prof. Sadeh used the Weizmann
Institute's geophysics observatory

near Eilat, headed by Prof. Ari
Ben Menahem.
Tel Aviv U. announced the re-
sults on March 17, crediting Prof.
Sadeh on Monday, however, both
institutions acknowledged that
Prof. Sadeh and Prof. Ben Mena-
hem were partners in the discov-
ery.
Albert Einstein predicted in
1917 that gravity acts in waves.
The prediction was part of his
General Theory of Relativity. But

Prof. Sadeh's innovation was
to use the earth as a detector,
but because the effect of the
waves is very small, a sophis-
ticated electronic system had to
be built by the university, and
the advanced equipment at the
Weizmann Institute facility had
to be employed.
