Edward Witten, who majored in History at Brandeis University, went on to win the prestigious Fields Medal in Mathematics. However, he recognized his talent for math and physics by the age of 21. According to Witten, the 50s, 60s and early 70s were a period of incredible discovery in elementary particle physics, during which numerous breakthroughs were made. The last major breakthrough was discovered by Gross, Wilczek, and Politzer a few months before Witten started graduate school, and it took him one year to understand it fully. The Standard Model involved novel mathematics that was unfamiliar not only to physicists but also to mathematicians at that time. Its exploration turned out to be very rich according to Witten, who is the only physicist to have won a Fields Medal. Witten has a Ph.D. in Physics and is now a Professor at the Institute for Advanced Study at Princeton University. While Witten has published a book on Maxwell's equations, which are linear, the Standard Model is based on a nonlinear version of Maxwell's equation. The model of the nuclear force theory is still largely unsolved, and Witten was only able to make very limited progress as a student. However, his interest in building models of elementary particle physics led him to explore the mathematical issues arising in the Standard Model. Witten found more opportunities exploring some of the mathematical issues arising in the Standard Model, leading to a renewed interaction between physics and math. In 1982 and 1983, John Schwarz, Michael Green, and Lars Brink made enough progress in string theory that Witten took their work seriously. However, Witten hesitated to get fully involved and spent a summer studying Schwzartz's review article on string theory. It was not until 1984 when he heard from a colleague in the faculty club at Princeton that the obstacles to string theory as a consistent theory had gone away, that he devoted himself to the subject. Witten has made numerous contributions and breakthroughs in string theory since then. String Theory Breakthroughs In August 1984, Green and Schwartz had a breakthrough in elementary particle physics that had a huge impact on the speaker's interest in the subject. By early 1985, with several co-authors, including Candelas, Horowitz, and Stromager, a paper was written giving a more detailed explanation of string theory. This ultimately led to questions about the landscape and the discovery of two more string theories. By 1995, the speaker was trying to show that some string theories were mathematically inconsistent. However, the unification of string theories resulted from an attempt to disprove some of them. The breakthrough of Green and Schwartz in August 1984 had a significant impact on the speaker's interest in elementary particle physics A paper was written in early 1985 with more detail about string theory, which led to questions about landscape and the discovery of two more string theories The speaker was trying to show that some string theories were mathematically inconsistent in 1995 The unification of string theories resulted from an attempt to disprove some of them In the early 90s, it was appreciated that suprasymmetric theories were an example similar to the standard model. The speaker added new clues that reduced the number of string theories by showing that they were different limits of each other. The story ended up adding this new limit that people sometimes call M Theory, which reduced the number of string theories. The speaker realized there was an error in their argument, but this led to the unification of string theories and the discovery of M Theory.
