When told that his theory Of rcla-
tsvity had stirred up much interest in
tne general public. aside from the coun-
try's scientists. the professor smiled
and protested incrcdibility.
mo, | can't explain why it should
interest the public in general Rather,
! think this question for psyche
pathological examination. From tho
scientific point of view the main value
is not in it's deduction, but in its logi-
cal simplicity; that is. the fact that q
few principles account for many COM
plicated events: These events are now
explained by fewer and less compli-
Gated principles than formerly. The
main facts that are explained are the
relativity Of movement and the equiva-
lence of the mass of inertia and the
mass of gravity.
IAN opinion, and q false one, has
been spread widely that the theory of
rclativity is something contrary to the
development of the science Of physics
from the days Of Galileo, Newton, Max
we'll and Lorentz. The contrary is true.
TAe theory is a natural outcome of the
work of these men,"
Answering a criticism made By an
American scientist that his theory can
not be proved. Professor Einstcin said
that in "A certain sense the same thing
can be said of any scientific theory. No
theory. he explained, can be proved ab-
solutely. Every theory tries to explain
number Of facts, but no theory can
prove that it is the only possible sum-
ming up Of these facts

done at the Mt. Wilson Observatory,
have not been brought into harmony
with my theory. European and Ameri-

studying it. 1t can't be so difficult" he
said, smiling broadly "My students in
Berlin seem to understand it,
Whether a mans outlook on life
will be altered by the theory of rela-
tivity depends entirely on his point
Of view. the professor contends From
the philosophical point of view, affect
ing the universe and indirectly life,
the theory introduces new conceptions
of time and space.
"What would you advise the layman
to do about the theory" the Professor
was asked.
Nothing at all. Tell him not to
worry. 1t won't hurt him"
