INAUGURAL LECTURE
From
a
theoretical
point
of view
however,
this
theory
does
not
grant
full
satisfaction because the
relativity principle
that
has
been stated
above
favors
uniform
[p. 742]
motion.
If
it is true after all that
uniform
motion
cannot
have
an
absolute
meaning
from the
physical point
of
view,
we
then have the obvious
question
whether
or
not
this statement
can
be extended to nonuniform motions. It turned out that
one
arrives
at
a
very
distinct extension
of
relativity theory
when
one uses a
relativity principle
as a
basis that is extended in this
sense.
In this
manner one
is led
to
a
general theory
[3]
of
gravitation
that includes its
dynamics.
At this
moment, however,
we
do
not have
[4]
the
experimental
material
necessary
to
test the
justification
of
the
introduction of this
basic
principle.
We have determined that inductive
physics
has
questions
for deductive
physics
and vice
versa;
and
eliciting
the
answers
will
require
the
application
of
our
utmost
efforts.
May
we,
by means
of
united
efforts,
soon
succeed in
advancing
toward
conclusive
progress.
