after
all.
The
idea
is,
at all
events,
worth
being
considered and carried
through
to
completion.
With
cordial
thanks
and
regards, yours very truly,

Weyl.
510. From
Margarete
Hamburger[1]
Berlin,
16
April
1918
Esteemed,
dear
Professor,
Accept my very
sincere
thanks
for
your
dear
little letter.
Your
so many
generous
words in
it about
a
couple
of small favors
I
was
allowed
to
render
you
touched
my
heart,
and
now
I
am
quite
embarrassed.
It
has
always
done
me so
much
good
to
be allowed
to do
something
for
you,
at
least in this
form,
and
you
would
please
me very
much also to want
to
see
behind the little material
gifts
a
mentality
full of
respect
and
gratitude
for
the
wonderful
person
Einstein.
Your
inspired
drawing,
which
gives me a glimpse
of
your
psychophysis
and
is
surely applicable
to
all
other
human
beings,[2]
amused
me very
much-after
some
reflection.
I
am
full of
admiration
for
the
simplicity
and
grace
with which
you
know how to make
physics
useful in
an
intuitive
way
to
very personal experience
and how
to
draw soul and nature under
a
single heading. My son,
who
explained
to
me
the
physical
apparatus,
also
enjoyed
this
original
symbolism
very
much.
With
warmest
regards,
which
my
son joins me
in
extending,
also to
the best
of
all
women,
I
am
yours truly,
Margarete Hamburger.
511. To Hermann
Weyl
[Berlin,
18
April
1918][1]
Esteemed
Colleague,
Busily
involved in
studying
the
details
of
your
book,[2]
I constantly
admire
anew
the
beauty
and
elegance
of
your
derivations.
Now, though,
in
the last
§
I
come
upon
a
conclusion
that
seems
to
me
to be
wrong.[3]
Namely, you
find
that
static,
spherically symmetric
solutions
correspond
to
the
elliptic type,
since
they
are
all
symmetric
with
respect
to
an
“equatorial
surface.”[4]
However,
the
latter
does
not
apply according
to
your
own
solution. For
you
examine
the
case
of
