Every generation benefits from the insights and discoveries of the generations who came before. “If I have seen a little further it is by standing on the shoulders of giants,” wrote Isaac Newton. In a special series, the World Science Festival invites audiences to stand on the shoulders of modern-day giants.

Professor Witten is a leading light of superstring theory and the only physicist to have won the vaunted Fields Medal, mathematics’ highest honor. Known for advancing a number of novel approaches in mathematics and physics, Witten opened up new vistas in 1995 when he unified five seemingly competing superstring theories into M-theory, which seeks to unify Einstein’s general theory of relativity with quantum mechanics.
