Einstein: His Life and Universe

. Holton 1973, 209–212. Einstein’s stepson-in-law Rudolph Kayser and colleague Philipp Frank both say that Einstein read Foppl in his spare time while at the Polytechnic.

. Clark, 59; Galison, 32–34. Galison’s book on Poincare and Einstein is a fascinating exposition on how they developed their concepts and how Poincare’s

observations were “an anticipatory note to Einstein’s special theory of relativity, a brilliant move by an author lacking the intellectual courage to pursue it to its logical, revolutionary end” (Galison, 34). Also very useful is Miller 2001, 200–204.

. Novi Sad, the cultural center of the Serbian people, had long been a “free royal city,” then part of a Serbian autonomous region of the Hapsburg Empire. By the time Mari

was born, it was in the Hungarian part of Austria-Hungary. Approximately 40 percent of the citizens there spoke Serbian when she was growing up, 25 percent spoke Hungarian, and about 20 percent spoke German. It is now the second largest city, after Belgrade, in the Republic of Serbia.
