proper
(Christmas
and
New
Year).
Otherwise
you are always
welcome.
The other
physicists
(Laue,
Kern, Herzfeld,
Weiss)[2]
left town
&
will
come
back
only
at
the
beginning
of
January;
but
they
would be
delighted
if
they
could
see you
in
spite
of that.
I
am
telling you
this
out
of
duty,
without
wishing
to influence
your
decision.
There
are
several
new
bits
of
science to be
noted:
progress
of
the
gravitation
theory.
Something
theoretical
on
the
specific
heat of rotation of
hydrogen.[3]
All
the
same,
little
in
comparison
with
the
enormous
effort! You
now
live in
an
incomparable
scientific
environment, which will
also,
of
course,
make terrible demands
on
you.[4]
When Lorentz
offered
me a job,
it
really gave me
the
creeps.[5]
Best
wishes from
my family
to
yours, your
Einstein
Let
me
know
as soon as possible
when
you
will be
coming.
Give
my
regards
to
the
highly
respected
Prof. Lorentz!
426. To
Otto
Marx[1]
Zurich,
22
December
1912
Marx
had
requested
Einstein's
assistance in
solving
a problem
with
an airplane.
...
I
was
delighted
to receive
your
splendid
and clever
present.
Whenever
I
look
through
the
album,
I'll remember
your
...
and
my
escapade
into
the realm of the
practical
with
amusement
...
With
kindest
regards
and
best
wishes for
the
holidays, yours
sincerely,
A.
Einstein
