2 days ago · Edward Witten. In the early 1980s, Edward Witten discovered that most theories of quantum gravity could not accommodate chiral fermions like the neutrino.
6 days ago · He has been intimately involved for a long time in research in this field, playing a major role in the geometric Langlands program and working together with both Langlands and Witten. Nordita this month is hosting a program on quantum gravity, aimed at covering a diversity of approaches. Videos of the talks are appearing here.
Aug 2, 2024 · String theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity. The name string theory comes from the modeling of subatomic particles as tiny one-dimensional ’stringlike’ entities.
2 days ago · Another conjecture formulated by Edward Witten states that three-dimensional gravity in anti-de Sitter space is equivalent to a conformal field theory with monster group symmetry. [68] These conjectures provide examples of the AdS/CFT correspondence that do not require the full apparatus of string or M-theory.
5 days ago · Edward Witten, whose work on invariants of manifolds and topological quantum field theories was influenced by Atiyah. Many of the papers in the 6th volume [106] of his collected works are surveys, obituaries, and general talks.

6 days ago · Edward Witten, chair of the selection committee, said: 'Jocelyn Bell Burnell's discovery of pulsars will always stand as one of the great surprises in the history of astronomy. Until that moment, no one had any real idea how neutron stars could be observed, if indeed they existed.
