2 3 6 D O C U M E N T 2 4 4 J U L Y 1 9 2 8 It is my conviction that the existence of Lessing University is already of great importance because it is clear that too little is being done to make the results of sci- entific research available even to nonspecialists. Lessing University has performed this task for many years with a high sense of responsibility, as is generally recognized by its standing in educational life and in the public sphere, and it seems to me an obvious duty of the general public to en- sure and promote the development of this institute. There can be no underlying doubt that with respect to promoting such free edu- cational institutions other countries, for example the United States, are far superior there a tradition has long since been developed, in accord with which wealthy pub- lic figures take it upon themselves as a nobile officium to promote such enterprises.[3] In our case, this should also be the appropriate route to pursue, and thus I would vigorously welcome it if a number of men with far-sighted understanding, acting in the public interest, were to be prepared to help promote Lessing University and join a board of trustees to be formed for this purpose. I hardly need to assure you that I will also gladly do what I can to help this plan succeed. Respectfully yours, A. Einstein 244. From Chaim Herman Müntz [Berlin-Nikolassee,] 26 July 1928 Dear, esteemed Professor, I take this opportunity to make a few matter-of-fact remarks, which will be quite brief, so as not to take up too much of your time for recuperation. They concern the fact that one can completely integrate the approximation equations[1] sign change for .
