Dear
Albert,
I
wonder whether
this
postcard
will still find
you
at
home?[1]
I
just
want to
tell
you
in
a
hurry
that the
Fft.
Oppenheimers
are
not
leaving
town,
so
be
sure
to
visit them.
You will find
Dr.
Eugen
O.
after
9:30
A.M.
at his office:
v.
Erlanger Sons,
Rossmarkt
14.[2]
I wish
you
a
good
trip &
send
my
love to all of
you.
Mama

Dear
Albert.
That
you were
not able to write
at
length-that
I already
knew,[1]
and that
you
received
my
letters, that,
too,
I
already
knew,
so
I waited
patiently
and
am
in fact still
waiting.
It
is
true that, in and
of
itself,
setting
X2
~
1-T
is
not
very
plausible;[2]
still I
don't
know whether
this invalidates the basic
assumption (setting
the
time
inversely
proportional
to
the
energy
for small
energies),[3]
which,
in
fact,
still looks
plausible
to
me.
Well,
the
experiments
you
are
planning to
do with
Sucki[4]
will show
whether the free
path
lengths,
as
obtained
numerically
for low-concentration
alloys
at
low
temperatures
from
my
formula, will fit
those
phenomena.
The
way
the
resistance of
pure
metals
behaves
at
very
low
temperatures,
where
I would
expect
1-,
and, along
with
it,
the
X
resistance
to be
proportional
to
the heat
content,[5] may
also
settle the
matter.
I
am
also
unsatisfied
as
regards
the
paradox
contained
in
the
delaying
of
an
electron:[6]
completely independently
of the
radiation
formula,
if
my
mathematical
argument
is
correct! That
one
arrives
by
two
different
ways
at
a
...
failure
to
understand the
delaying
of the
electron,
makes
me
wonder,
naturally,
whether
the old
theory,
perhaps
in
conjunction
with
the
paradox
of the constitution of the
electron,
might
not already
involve,
as
far
as necessary,
the
quantized nature
of the
emission
of
light.
Wien's
displacement
law
permits
us
to draw conclusions
about other
regions
(especially
the
region
of
low
temperatures,
which
is
important
for
drawing
conclusions
from the
quantum
hypothesis)
from the
experimentally
known
region
of
radiation;
after
all,
it
is
only
in this
sense
that Planck's radiation formula
can
be
regarded
as having
been
