is
the
duty
of the
well-to-do
people
in
Germany
to
promote
these
splendid
endeavors
a
bit
by providing
financial
support.[6]
Since
even
the
theoretical natural
scientist
already
has
considerable
expenses
for
the
acquisition
of
indispensable literature,
the
gentleman
would like
to promote your
work
by
putting
at
your
disposal
a sum
of
15,000 marks,
payable
in
three installments of
5,000
M.
each,
the
first
immediately,
and
the
two
others
in
1911
and
1912.[7]
Let
me
note
that
the
acceptance
of
this
grant
would
not
entail
any
duties whatsoever
on
your part,
and
that
you
would not be
subject
to
any
restrictions
in
spending it.
As
soon as you
inform
me
of
your
acceptance,
I will
arrange
for
the transmittal of
the
first
payment
of
5,000
M.
Respectfully
yours,
231. To Jakob
Laub
Zurich, 4
November 1910
Dear
Mr. Laub:
First of
all,
many
thanks
for the
truly
artistic
little
book,
which
was
very
well
received.
And then
all
the
pain
because of that
crazy L![1]
You
are right
to
look
around
for
something else,
and I will
gladly
be
of
help to
you.
The address
to
which
to
write
Gilbert
Lewis
is
"Research
Laboratory
of
Physical Chemistry
of the
Massachusetts
Institute of
Technology.
Boston."[2]
So
far
I
have
not
received
a
call
to
Prague.[3]
At
the
moment I
am very
hopeful
that
I will solve the radiation
problem,
and
that
I will do
so
without
light
quanta.
I
am awfully
curious how the
thing
will
turn out.
One would have
to
give
up
the
energy principle
in its
present form.[4]
Give
my very
kind
regards to
Hertz.[5]
I wrote
a
note
concerning
his
paper
and
am
enclosing
it,
so
that
he
can
tell
me
whether
he
agrees
with
it.[6]
Recently
I received several
papers dealing
with
the
theory
of
relativity
from
a
Japanese
(F.
N.
Tohyo Sugaku-Butwigakkwai Kizu,
2d
series,
vol.
5,
no.
18), among
them
one
on
ponderomotive forces.[7]
In
my
opinion
this
is
thus far the
only
paper
written
on
this
topic
that
makes
sense.
For substances
with
constant
fx
and
e
his
results
seem
to
me
to be correct. But he too has
(iB),
so
that
his
results
can
hardly
be valid for
hard
magnetic
bodies
(magnetized
disk).[8]
The interference
experiment
had
already
been tackled
by
Weiss. But I
am no
longer
so
curious because
I
no
longer
believe
(at
the
present)[9]
in
spatial
light
quanta. I
don't
know
exactly
when
I
will be
leaving
for
Leiden,
probably
in the
second
half of
January.[10]
Best
regards, your
A.
Einstein
Please
tell Mr.
Hertz
to
send
me
back the note
or,
better
still,
to forward it
directly
to
Mr.
Wien.[11]
