Felix Warburg, for example, is a splendid man, even if he’s a lousy musician.[5] I’m sorry that you have to suffer from these unfortunate circumstances, and I long for nothing so much as that you soon get another position in Europe.[6] Naturally, I will advise everyone not to go to the university in Jerusalem. But if someone nevertheless wants to go, I will gladly write to tell him that he can have confidence in you. You need not keep the content of the letter secret, but it should not be printed. Kind regards, your A. Einstein Regarding my health, it is not better. 232. From Jakob Grommer[1] Berlin, Thursday, 28 June 1928 Dear Prof., There is a problem, that in the static case (i.e., when everything is independent of and ),[2] it follows from the equations that is con- stant, and in fact both from Eq. I as well as from Eq. II.[3] Likewise, there is a prob- lem in the centrally symmetric case also without an electromagnetic field. If one presumes Weyl’s (Schwarzschild’s) solution[4] here and then also takes , then in both cases I and II,[5] one finds for the antisymmetric the following equations: Eqns. 1) , , and 2) , ,[6] where = const., and that is, how- ever, all. Is it possible to satisfy both 1) and 2)? Eq. 2) alone already seems to be impos- sible. You said that I and II differ in terms of their compatibility. I don’t understand that. According to I, we have 3) and 4) . x 4 hk4 0 k 1 2 3. = = 4 i x -------- x i --------- 0 = = h h 0 = 1 2 3 4 = hl,l x r 3 -------- - = k l , 1 2 3 = h4ll konst. = h , , – h h – + = h h – h + =
