DOC. 42 SPECIAL AND
GENERAL RELATIVITY

The
Experimental
Confirmation
of
the
General
Theory
of
Relativity

tained
during
the
eclipse
and
the
comparison photographs
amounted
to
a
few
hundredths of
a
millimetre
only.
Thus
great accuracy
was
necessary
in
making
the
adjustments
re- [92]
quired
for
the
taking
of
the
photographs,
and in their subse-
quent measurement.
The
results
of
the
measurements
confirmed the
theory
in
a
thoroughly satisfactory manner.
The
rectangular components
of
the
observed
and of
the calculated deviations
of
the
stars
(in
seconds
of
arc) are
set
forth
in the
following
table
of results:

In Section
23
it
has
been shown that in
a
system
K' which
is
in rotation with
regard to
a
Galileian
system
K,
clocks
of
identical
construction,
and which
are
considered
at rest
with
respect to
the
rotating reference-body,
go
at rates
which
are
dependent
on
the
positions
of
the
clocks. We shall
now
ex-
amine this
dependence
quantitatively.
A
clock,
which
is
