D O C U M E N T 1 9 3 M A Y 1 9 2 2 1 6 9 Gilbert Murray, and the report by Mr. Hanotaux, adopted by the Council on 14 Jan- uary 1922.[16] I would be happy to furnish you with any additional information you may want. I permit myself to express in the name of the Council of the League of Nations the sincere hope that it will be possible for you to accept this invitation. Very respectfully, Secretary General. 193. To Paul Ehrenfest [Berlin,] 18 May 1922 Dear Ehrenfest, I already took care of Joffe,[1] although he’s away from Berlin at the moment. I want to invite him alone and use the time well to initiate contacts with him. I’ll make sure that the request by the Dutch geologist is fulfilled.[2] Thank you for deal- ing with the things that arrived after me. The Zionists are shameless and pushy I have difficulty always assuming the proper stance each time, considering that I am, of course, sympathetic to the cause. Breit’s hypothesis is not acceptable because the strong electric molecular inter- actions surely far outweigh the weak magnetic fields and produce statistical disorder.[3] If you say the atoms adjust unadiabatically to the magnetic field at the instant of vaporization, that’s a hypothesis without any sort of legitimacy. For, as long as the interaction with other atoms persists, it causes disorder. Once the inter- action has ceased, though, the orientation problem is the same as at any other time. Unadiabatic adjustment means doing without theory but adds other difficulties. How should the temperature influence be accounted for in the adjustment based on paramagnetism? (It should occur even in this case without collisions, shouldn’t it?) (How are you faring, esteemed southern orbit?) I wouldn’t say any- thing about this eventuality in the note.[4] Regarding the problem with the factor 2, I was thinking that two transitions are surely involved in the repositioning, but that the a priori probability of the mean state vanishes with a vanishing magnetic field, hence that the absorption probability is much greater for this state. This question doesn’t affect us, by the way, thank God. I’m very curious about the Breit-Borelius hypothesis, especially if, as you say, it’s testable. e E KT –-------
