JUNE
1912 307
time
ago,
at
the
beginning
of
April,
when
we
reopened
our
house.
We had
&
still have
many
worries,
the
greatest
of
them
on
account
of
the chronic illness
of
my
mother-in-law
in
Frankfurt.
My
wife
is
now again
at
her
side.
(Prior
to
that,
she
arranged
lodgings
for
Toni in
Loschnitz
near
Dresden,
where Prof.
Auer
is to
give
violin lessons this
summer.)
Only
our
dachschund "Waldi"
keeps
me company
at
present.
I
hope
that
my
wife will
be back next week.
At the end of
March,
on
my way
back from
Italy,
I also visited
the
Ansbachers in Milan
&
found them
in
good
health. About
everything
else,
orally.
How
are
things going
with the
problem
of
an
apartment
here? Have
you
made
progress
with
your paper
on
the
gravitation
problem?-Tonight
I
am going
to Hurwitz's.
With best
regards
to all
of
you,
as always,
your
Alfred Stern
406. To
Heinrich
Zangger
[Prague,
after
5
June
1912]
Dear friend
Zangger,
It
is not
nice of
me
that
I
did not
answer
your many
postcards.
This
comes
from
my
great
sluggishness.
But
I
am sure
you
are
not
angry
with
me
for that. Kaufler
visited
me
recently,
to
my
great
delight.
He
is
very knowledgeable;
it is
a pity
that
we
do
not
have
him in
Zurich.
I
work
diligently
but
accomplish
rather
little;
let's
hope
that better times
will
come
again!
Around
August
1,
I'll
move
back
to Zurich,
bag
&
baggage,
&
am
very
happy
about
it.
In the meantime
I
had
to
withstand
several
onslaughts
of
job
offers.
That
H. A.
Lorentz wanted
me
to
come
to
Leiden
you
already
know.
In
addition,
Warburg
wanted
to
juggle me
to
the Reichsanstalt
in
Berlin,
and
the Austrians
offered
me
under the table
an
appointment
at
Vienna
in
1913
with
a salary
of
20,000
Kronen.
But I
refused
to
consider
anything
before
I
get
settled
in
Zurich. It
would have
been
very ignoble
to "sell"
myself
behind their
back.
I
am
sure
that
this
is
also
your
view.
At the
present
I
am
engaged
in
an amusing
polemic
with
Abraham,
and
also in
one
with J. Stark.
The latter
is
getting
his due.
Abraham
has
accepted
my
most
important
new
results
concerning
gravitation.
The further
development
of
the
theory
of
gravitation
meets
with
great
obstacles. In
the
theory
of
quanta,
a
great
advance has
been made
by
Sakkur
(chemical
constant
of
gases).
The
improvement
on
my
theory
of
specific
heats
by
Born and
Karman,
or
Debije,
is
also
a
great
advance. Most
recently,
Laue
made
a
great
discovery
about the
bending
of
Roentgen
rays.
I will tell
you
about
it.
Weber's
death
is
good
for
the
Polytechnikum.
The
thing
now
is
to find
a
capable
electrical
engineer,
which will not be
easy.
Unfortunately, I
cannot have
a say
in
this
area,
because
I
am
not
much
at
home
in
electrical
engineering.
Cordial
greetings
to
you
and
your
family
from
your
Einstein
