Fascinating account of the great man's first visit to America, a visit that was intended to promote physics but also zionism, and his encounters with American "high-society" Jewry, including Louis Brandeis, Felix Frankfurter, Arthur Sulzberger (those who claim the New York Times has an anti-Israel bias should note that this bias has old roots) and Bernard Baruch. No math is required. This is primarily a story about politics and culture.
Though the American Jews come off as small, short-sighted, and indeed a bit foolish considering what was coming, perhaps both sides were right, concerning their sides of the Atlantic: assimilation and engagement with the Other have well served America's Jews, while European Jewry, in 1921, needed nothing so much as a prophet, warning them to get the hell out of Europe or be willing to fire a rifle. They had one, in Chaim Weizmann, who accompanied Einstein, but not enough of them listened.
Parenthetically one wonders what the world would be like today if America had been more open to Jewish emigration from Europe at the dawn of the last century, or had stayed warlike after 1918, but of course America has never been able to save Europe from its barbarous self. Europe is the cradle of our civilization, and its grave.
