whether these two lights interfere. The experiment is simple, it’s just that the leaf
shouldn’t get too
hot.[8]
Warm regards to both of you from your
Papa.
Did you see the son of the pastor from Florence, d[ear] Albert? If not, get to it. Pauli
was very sick
(pleurisy).[9]
It would be nice if both of you wrote my sister a post-
card sometime; she would be very pleased. Her address is Dr. M. Winteler.
Giuseppe Verdi Street, Fiesole near Florence. What’s the situation with the apart-
ment? Why do you have to move out? You’d have it incomparably more convenient
in
Germany.[10]

Dear Albert,
In attachment I send you my
dissertation;[2]
there is something very wrong and
questionable about this paper, you see, and I turn to you in my distress.
It involves the following:
After you had looked through the paper in the
fall,[3]
I introduced the general
tensor argument following your
directions,[4]
and then, after Ratnowsky had also
checked the paper again and had found everything to be in the finest
order,[5]
I sub-
mitted it to Prof.
Schrödinger.[6]
Can you imagine my shock when shortly afterwards Prof. Schrödinger pointed
out a few very disturbing weaknesses in the theory that actually place the entire
solution to the problem in question! Namely:
1) The coefficients of the ’s derived from gas kinetics do not agree
with the coefficients of the tensorially derived pressure component (they even have
different signs):
Tensorial: Gas-kinetically:
