279. To Satyendra Nath Bose
[Berlin,] 2 July 1924
Dear Colleague,
I have translated your paper and submitted it to the Zeitschrift für Physik for
printing.[1]
It constitutes an important advance and I liked it very much. I think,
however, that your
objections[2]
to my
paper[3]
are not correct. For Wien’s displace-
ment law does not presuppose the wave theory, and Bohr’s correspondence princi-
ple is not used at all. Nevertheless, that does not matter. You were the first to derive
the factor quantum-theoretically, even if not entirely strictly due to the polarization
factor
2.[4]
It is a fine advance.
With friendly greetings, yours,
A. Einstein.

Highly esteemed colleague,
On behalf of our Society of Friends of the Jerusalem Library, I turn to you with
the humble request that you kindly support us in our efforts of cultivating culture
and science in the Orient through a library for the Hebrew University in
Jerusalem.[2]
