Abstract
Duality has a long history in physics going back to the electromagnetic symmetry discovered by Dirac in 1931 and and by the duality symmetry of pf the two-dimensional Ising model of Statistical mechanics discovered by Kramers and Wannier in 1941. By now there are many extensions and generalizations of duality isn several areas of physics ranging from condensed matter to quantum field theory and gravity. In the talk I will give brief sketch of this rich history, focusing on recent discoveries. Duality is often a mapping that relates a strongly coupled theory to another weakly coupled one, often with seemingly different nature. I will end my colloquium showing for duality has helped understanding a mysterious symmetry seen in experiments in quantum Hall fluids.
