From Max Laue
Feldberg,
Schwarzwald,
27
December
1907
Dear
Mr.
Einstein:
Only
now
that vacation
time
is
here
again,
do
I
get
around
to thanking
you
for
your
kind
letter
of Nov.
5.
As
you
will have
already
guessed
from
the
postmark,
I have
come
to
ski
on
the
Feldberg, and,
therefore, for want of
any
books
I
am
not able to
deal
with
the manifold
suggestions
in
your
letter.
All
I
am
going
to
say
is
that
I
wish to tell
you
I
am
very pleased
by
your
giving
up
the
theory
of
light
quanta.
As
you
know,
I
never
had much
use
for
it. I
do not
consider
it
an
easy
task
to find
a
statistical
theory
of
radiation.
I
toiled
at it
a
little
myself
when I
studied
the influence
of coherence
on
the
entropy
of
ray bundles,
but
soon
I
gave
it
up
for
want
of
any
points
of
attack.[1]
Still,
I
believe
I
can freely
recommend
to
you-and
this not
just out
of authorial
vanity-to
take
a
look
at
these formulas
one
of these
days,
if
you
have
not
done
so already.
At
the
very
least
they
shed
new light
on
the
question.
I
am
in
the
greatest
suspense
about
your new
conception
of
gravitation.[2]
Please
send
me a
reprint
as soon as
possible.
Do look
up
the article
by
J.
Stark
in
the
last
issue
(No. 25)
of
the
Phys.
Zeitschr.; perhaps
you
must protect
your priority,
even
though
you
are
cited in such
an
offhand
way.[3]
I
have
given
much
thought to
your
remark about Jeans's derivation of the
relativity
principle,
but
I have
not
understood
it.
It
would be
of
great
interest
to
me,
and
probably
to
others
too,
if
you
would
publish your
modification of Jeans's
idea.[4]
Actually
I
wanted
to
write
more.
But
here
in the
hotel
one
keeps getting
interrupted.
Therefore
I will
only
add
a
wish for
a happy
New
Year
to
you
and
Mrs.
Einstein
and with
that
I
will
conclude for
today.
With
best
regards, your
M.
Laue
I
completely
forgot
to
mention
your
reprints
and the
postcard.
Sincerest thanks
for
both!

To
Marcel Grossmann
Bern, 3 January 1908
Dear
Marcel!
At
the risk
of
having you ever
so
gently poke
fun
at
me,
I
must
ask
you
today
for
advice
on
a
practical
matter.
I
would like
to make
an
attempt
at
a
teaching position
at
the Technikum Winterthur
(mathematics
and
physics)
that
will
probably
become
vacant
