What is The String Theory? By Edward Witten

Edward Witten tells us about string theory, and frames it as an attempt to make sense of all the phenomena we see in nature as one unified theory

“Edward Witten (/ˈwɪtən/; born August 26, 1951) is an American theoretical physicist and professor of mathematical physics at the Institute for Advanced Study in Princeton, New Jersey.

Witten is a researcher in string theory, quantum gravity, supersymmetric quantum field theories, and other areas of mathematical physics.

In addition to his contributions to physics, Witten’s work has significantly impacted pure mathematics.  In 1990 he became the first and so far the only physicist to be awarded a Fields Medal by the International Mathematical Union. In 2004, Time magazine stated that Witten is widely thought to be the world’s smartest living theoretical physicist.” Source: https://en.wikipedia.org/wiki/Edward_Witten
