Aaron Brown What’s Love Got to Do With It? Edward Frenkel is writing a protracted Dear John letter to popular misconceptions about math and mathema- ticians… he great popular science and science fiction author Isaac Asimov told a story about a university committee meeting in which there was much laughter and joking about a student named “Milton” flunkingT English literature, but no one noticed when a student named “Gauss” was failing in mathematics. I wish I could find the reference to this, but I read it long ago in childhood, and some Internet searching proved fruitless. I may have the details wrong – especially the name of the student date are smaller than Asimov’s. They also have cians, and writers. With these people, screenwriters flunking English literature – but I remember the a different slant. Asimov tried to show every- often assume they must be tortured to be authentic. point.

The first step in Frenkel’s unorthodox strategy is to include brief but poignant autobiographical a pure mathematician, exploring abstract details. He skillfully sketches a character who is shy and brilliant, tough and sensitive. He has the relationships for the love of it great misfortune to be born under Communism, and in particular to be Jewish (according to USSR the extent that professional mathematics tolerates Malcolm is even more radically applied.
