From
David
Hilbert
[Göttingen,
19
November
1915]
Dear
Colleague,
Many
thanks
for
your
postcard
and cordial
congratulations
on conquering
perihelion
motion.[1]
If
I
could calculate
as rapidly
as you,[2]
in
my equations
the
electron would
correspondingly
have to
capitulate,
and
simultaneously
the
hydrogen
atom would have to
produce
its note
of
apology
about
why
it
does not
radiate.[3]
I
would be
grateful
if
you
were
to
continue to
keep
me
up-to-date
on
your
latest
advances.
Greetings, yours,
Hilbert.
150. To
Hans Albert Einstein
[Berlin,
23
November
1915]
My
dear
Albert,
So,
we
would
like
to meet
in Winterthur and drive
together
to
Krummenau
where Mr. Besso
lives.[1] We
shall
both
stay
at
the
inn
there, though.
I’m
looking
forward
to
it
very much, especially
since
I’ve
been
working
terribly
hard
recently.
Write
to
me
very
soon
about which
day
we
should
meet,
since
preparations
for
such
a
trip
take
up
a
lot
of
time
now
during
the
war.
Do write
me
sometime
soon!
You
are
almost
as
lazy
as
your
old
father
at
writing.
Kisses
to
you
and Tete from
your
Papa.
Regards
to Mama.
151. To
Erwin Freundlich
Berlin,
Wednesday
[24
November
1915][1]
Dear
Freundlich,
I just
came
back from
Naumann,[2]
who has answered
me
now
after
all.
I
poured him
a
heavy
dose
of
the
truth,
commended
you highly,
and took Struve’s
protectionism soundly
to
task.[3] I
asked him
sincerely
to
give
you
the
observer
