2 1 0 D O C U M E N T S 2 6 3 – 2 6 5 J U L Y 1 9 2 2 I remember with special pleasure the hours of harmony I spent with you, Lan- gevin, and the other nice colleagues in Paris.[5] I am very particularly grateful to Langevin, whose touching solicitude I shall never forget. Weyl wrote similarly enthusiastically about him to me from Zurich.[6] Please convey to him my cordial greetings and accept my amicable regards to you personally from your. 263. To Eric Drummond Berlin, 4 July 1922 Highly esteemed Sir, In consideration of circumstances that became clear to me only since my accep- tance of 30 May of this yr., I see myself unfortunately compelled[1] to decline the nomination to the “Committee on Intellectual Cooperation” retroactively, after all.[2] I would not like to fail to take this opportunity, however, also to express my warmest sympathy with your efforts toward nursing international relations back to health.

Hatfield [Berlin,] 4 June [July] 1922[1] Highly esteemed Mr. Hatfield, I am very sorry for not having been able to answer you before now.[2] I am vir- tually convinced that your explanation is mistaken. The equipartition theorem of statistical mechanics demands very generally that the kinetic energy per degree of freedom always have the same value at a given ambient temperature. So there is no possibility for assigning to the surface a temperature different from the body’s inte- rior. Neither can the anomalies collected in quantum theory change anything here. Best regards, yours. 265. From Sigmund Einstein[1] [Baden-Baden,] 4 July 1922 Very esteemed Professor, As fellow namesake and so humbly my best regards I send to you
