searching for a recipe to calculate helium and the other atoms; but I’m not succeed-
ing in that, either. My encyclopedia article has
appeared;[8]
I shall be sending you
a copy in the near future. Otherwise, I am spending my time reading, going on
walks, occupying myself with the children and with music. I am practicing system-
atically and have, I believe, made some advances. Unfortunately, it is very difficult
here to call together a trio or a quartet.—In the last Annalen issue, where the fine
paper by Grüneisen and Goens on testing your theory of dissociation speed
appears,[9]
there is an article by Gerold von Gleich on Mercury’s
perihelion,[10]
the
tone of which I don’t like at all. Will you say anything in response to it? It really is
strange that so many people have absolutely no sense for the intrinsic probability
of a theory. Did you make any progress with the affine world?
Greet your wife very warmly from both of us. Yours,
Born.
106. Recommendation for David Reichinstein[1]
[Berlin,] 27 August 1923
I have known Dr. Reichinstein for a long time already, both personally as well
as through his articles. There is no doubt that the experimental and theoretical re-
searches by Mr. Reichinstein in regard to the chemistry and physics of boundary
layers between solid and liquid, or gaseous phases, have revealed aspects from
which one may anticipate a substantial contribution toward the elucidation of this
difficult field. Pertinent technical problems have also been occupying Mr. Reichin-
stein for years.

107. To Heinrich Zangger
[Berlin,] 29 August 1923
Dear friend Zangger,
I’m not going to Bonn
now,[1]
after all, because it doesn’t fit into my schedule at
all. I am getting along excellently with Albert
again.[2]
We are spending the first
three weeks of September together in Kiel. Then he has
exams.[3]
Tete looks good;
all three of us were visiting Anschütz in
Lautrach.[4]
At the end of September I have
to go to Leyden. Then from mid-October on I’ll be back in Berlin.
