Einstein’s often-mentioned question concerning the limits
of the describability of reality through a continuum. Apolo-
gizes for his philosophical remarks about relativity theory,
but is glad to be able to agree with Einstein’s comments on
politics. [9 088].
TLS and TTrL from Friedrich Glum on behalf of Max
Planck. Attaches a copy of a letter of Mendelssohn & Co of
27 July to board of trustees of KWIP. Referring to corre-
spondence with Einstein, Magnus sent back 1,001.80 M
from the 3,000 he had been allotted. GyBP, I. Abt., Rep. 34,
Nr. 8, Mappe Mendelssohn. [77 891].
1-page TLS from Robert W. Lawson. In answering Ein-
stein’s nonextant card, he reconfirms that he envisions trans-
lating a lecture, even if a short one. Congratulates on
Einstein’s appointment as Special Professor in Leyden.

1-page TLS from Gösta Mittag-Leffler. Solicits an article on
Poincaré for a memorial volume of Acta Mathematica on
Karl Weierstrass, Sonya Kowalewski, and Henri Poincaré.

August 17 AKS to Ernst Schuchard. “[…] Nach meiner Meinung ist
die Reaktionskraft des elektrischen Windes wegen
schlechten Wirkungsgrades als Mittel zur Erreichung des
von Ihnen erstrebten Zieles ungeeignet […]” Stargardt Auk-
tion Katalog 11–12 June 1986, lot 311. [73 408].
August 20 2-page TLS from Edouard Guillaume. Apologizes for the
delay in replying to Doc. 94, due to his holiday. Continues
to expound on his anti-relativity theory, which rejects the
relativity of simultaneity and therefore concludes that there
is no such effect as time dilation (in either special or general
theory).

dau’s invitation, forwarded by Hans Mühsam, to visit with
