we
call
the
system
a
solution,
at lower
temperatures,
a
chemical
compound,
which
is
completely
unjustifiable
as
absolutely
no
qualitative
differences exist. Of
course,
this
impression
is
unimportant
practically,
because at
low temperatures
the
entropy
of
the
solution
differs
only
very
little
from
the
most
probable representative
compound.”

final
paragraph:
“Your
distinction
between
case 1
and
2
also
seems
to
me
legitimate.
For
whether
1 or
2
occurs
depends
on
entirely secondary
conditions:
the
size
and
position
of the
open
connections between
the
chambers. Such conditions
surely
cannot
possibly
have
an
influence
on
the
system’s entropy
value.
But-and
this
is
the
main point-one
can
always
transform
case 1
into
case 2,
provided
that
a
long enough
cooling
time
is
chosen.”
202. To Hans Albert Einstein
[Berlin,
16
March
1916]
My
dear
Albert,
The
explanation
for
the
curious
signature on my
last letter
is that,
in
my
absent-mindedness,
instead
of
signing
my
own
name,
I
frequently sign
for
the
person
to whom
the letter
is directed.[1]
So,
in
the
beginning
of
April
I’m
go-
ing
to
try
to
come
to Zurich. If
I’m not
allowed
out,
we’ll
meet
at
the border
(Gottmadingen
near Schaffhausen).[2]
At all events I’ll be
staying
at
an
inn
so
that
we’ll
be
completely by
ourselves
without
any strangers along.
Congratula-
tions
on
passing your
examination. Which school
are
you going
to now?[3] You
still make
so
many writing
errors.
You must take
care
in this
regard;
it
gives an
odd
impression
when words
are
written
incorrectly.[4]
I would
like
most to
be with
you
outside of
Zurich,
because in Zurich
there
are
too
many people
I
know. The main
question
is
whether
I
can come
across.
Kisses
to
Tete and
greetings
to
Mama from
your
Papa.
Give Mr. Besso
my regards
when
you
see
him.
203. To
Wilhelm Wien
Berlin, 18
March
1916
Highly
esteemed
Colleague,
Enclosed
herewith
is
my complete
revision
of
the
general
theory
of
relativity
for
the
Annalen.
As I
have
consigned publication
of the
offprint
to
