input: Text: Folie <unk> People with high IQs tend to be nearsighted. This is not because they read a lot or stare at computer screens too much. That common-sense hypothesis has been discredited by research. Rather, it is a matter of genetics. The same genes that tend to elevate IQ also tend to affect the shape of the eyeball in a way that leads to myopia. This relationship--known in genetics as "pleiotropy"--seems to be completely accidental, a quirk of evolution. Could there be a similar pleiotropy between madness and mathematics? Reading this absolutely fascinating biography by Sylvia Nasar, an economics writer for the New York Times, I began to wonder. Its subject, John Nash, is a mathematical genius who went crazy at the age of 30 and then, after several decades of flamboyant lunacy, was awarded the Nobel Prize in economics for something he had discovered as a graduate student. (He is now about to turn 70.) Nash is among the latest in a long and distinguished line of mathematicians--stretching back to that morbid paranoiac, Isaac Newton--who have been certifiably insane during parts of their lives. Just in the last 100 years or so, most of the heroic figures in the foundations of mathematics have landed in mental asylums or have died by their own hand. The greatest of them, Kurt Gödel, starved himself to death in the belief that his colleagues were putting poison in his food. Of the two pioneers of game theory--the field in which Nash garnered his Nobel--one, Ernst Zermelo, was hospitalized for psychosis. The other, John Von Neumann, may not have been clinically insane, but he did serve as the real-life model for the title character in Stanley Kubrick's Dr. Strangelove. So maybe there is an accidental, pleiotropic connection between madness and mathematics. Or maybe it isn
