Geometry: From Riemann to Einstein and On to String Theory - Shing
String theory says we live in a ten-dimensional universe, but that only four dimensions are accessible to our everyday senses. According to theorists, the missing six are curled up in bizarre structures known as Calabi-Yau manifolds. Shing-Tung Yau is the man who mathematically proved that these manifolds exist. He is the Graustein Professor of Mathematics at Harvard University. He has won many awards, including the Fields Medal, the National Medal of Science, a MacArthur Fellowship, the Crafoord Prize, Wolf Prize and the Veblen Prize. In 1993 he was elected to the National Academy of Sciences. His list of publications includes twenty books, including The Shape of Inner Space, in which he argues that geometry is fundamental not only to string theory but also to the very nature of our universe.
