KNOTS & QUANTUM THEORY | EDWARD WITTEN
IAS | INSTITUTE FOR ADVANCED STUDY | 2011
A knot is more or less what you think it is — a tangled mess of string in ordinary three-dimensional space .
In the twentieth century , mathematicians developed a rich and deep theory of knots .
Surprisingly , as Edward Witten , Charles Simonyi Professor in the School of Natural Sciences , explains in this lecture , it turned out that many of the most interesting ideas about knots have their roots in quantum physics .
