voltages
lower
than
1/
1000
volt,
which
is
an
unparalleled
sensitivity
for
the
measurement
of electrical
quantities (because
no
auxiliary
charge).
If the method
proves
still
to be
good
for
voltages
100
times
smaller,
then
nothing
stands
in the
way
of
an
experimental
test,
of the
limit
of
validity
that
is required
for
electrostatics
by
the molecular
theory.
Give
my
best
regards
to
Prof.
Kowalski[6]
I shall be
very
pleased
to show
you
the instruments
at
work
when
I have
reached that
stage.
It
is
no
small
matter to
do
experiments
when
one
has
so
little time &
no
laboratory,
and has to
depend
on
one's
own
(thin)
pocketbook!
Thanking
you
in
advance,
and
with
my
best
regards to
you
and
Mrs.
Gockel,[7]
I
remain

Dear
Solo,
Your
excuses are
uncommonly gracefully
worded,
but
this does not
make them
any
less idle.
Sleepless nights can
probably
be
accomplished splendidly
at
our place,
in
no
way
inferior
to
the
sleepless Academy half-nights,
which I still
remember
with
great
pleasure.[1] Thus,
your
excuses are
not accepted,
instead
your
assent
is
definitely
expected.
Cordial
greetings
from
your
A.
Einstein

To Johannes Stark
Bern, 14
December
1908
Highly
esteemed Professor
Stark:
Unfortunately
it
is
absolutely impossible
for
me
to write
that
book,
since
it is
impossible for
me
to
find
the
necessary
time.[1]
Each
day 8
hours of
strenuous
work
at
the
patent
office,
and
a
lot of
correspondence
and
studying
on top
of
it-surely
you
know
that
from
your
own
experience.
Several
papers
are
not
completed
because
I cannot find
the time
to
write them
up.
Add
to this
a
small
laboratory
for
electrostatic
experiments
that
I have cobbled
together
with
primitive
components
in
order
to
work
out
the
electrostatic method that
I published
recently
in
the
Physikalische
Zeitschr.[2]
