Highly
esteemed
Colleague,
I
am engaged
in
developing
fully
the
general
theory
of
relativity.
In
about
two
weeks
the
manuscript will
be
finished.[1] I
would
like
to
publish
this
detailed
paper
in
the
Annalen,
if I
were
granted
the
right
to separate
publication
of
the
article
by
a
publisher
of
my
free
choice. I
ask
you please
to
inform
me
whether
such
a
procedure
is
permitted
on
the
part
of
the
journal
and
the
publisher.
With
regards
from
your very
devoted
colleague,
A.
Einstein.

My
dear
Adn,
I
send
you greetings
from
here.[1]
In
a
month
I’m
going
to
be with
you
in
order
to
go on a
walking
tour
with
you.
It’ll be
very
nice.
Write
to
me soon
when
you
have
holidays.
If it’s not
convenient,
I’m
going
to take
you
out
of
school
for
one
week.
What’s
the
news
on
your
examination?[2]
Kisses to
you
and Tete from
your
Papa.
198. To Otto Stern

Dear Mr.
Stern,
Your
example
is
very
instructive.[1]
At
T
=
0
the
molecule
is
at
the bottom. That
means
the
mixed
crystal
does not
exist, only
the
chemical
compound
does.[2]
In
this
case
entropy
actually
does
vanish
