Topology and quantum physics
April 4, 2011 — University of PortoSpeaker: Sir Michael Atiyah (about) Abstract: Geometry and Physics have been closely linked, at least from the time of Galileo and Newton. Forces turn straight line motion into curved paths and the fundamental link between curvature and force persists into Maxwell’s theory of ElectroMagnetism and Einstein’s theory of General Relativity. 20th century Physics was dominated by Quantum Mechanics, and it took a long time to realize that this has close links with Topology, the branch of Geometry where measurement is unimportant and which is typified by the study of knots. I will try to explain this story in nontechnical language, using only high school geometry and physics. Time: 15h Room: Edifício da Matemática da FCUP Video streaming: here
