Sir Roger Penrose, a hybrid mathematician-cosmologist, is one of the most accomplished scientific thinkers of the past fifty years. In this compelling interview with Graham, Penrose describes some of the key events of his remarkable career.
This is the second part of Graham’s interview with Nima Arkani-Hamed, recorded at the Institute for Advanced Study in Princeton. Here, Nima is in brilliant form as he recalls how he fell in love with scattering amplitudes – aptly described by the theoretician Lance Dixon as ‘the most perfect microscopic structures in the known universe.’
Michael Green is one of the pioneers of the string framework. In collaboration with the Caltech theorist John Schwarz, he made a crucial breakthrough that led in 1984 to the what became known as the First String Revolution.
Edward Witten is widely regarded as the pre-eminent theoretical physicist of the past four decades. Based at the Institute for Advanced Study in Princeton, he has made dozens of path-breaking contributions to both physics and mathematics.
