T-duality
Videos
In theoretical physics, T-duality is an equivalence of two physical theories, which may be either quantum field theories or string theories. In the simplest example of this relationship, one of the th

In theoretical physics, the anti-de Sitter/conformal field theory correspondence is a conjectured relationship between two kinds of physical theories. On one side are anti-de Sitter spaces that are us
A hologram is a two-dimensional image that stores information about all three dimensions of the object it represents. The two images here are photographs of a single hologram taken from different angles.

Gerard 't Hooft obtained results related to the AdS/CFT correspondence in the 1970s by studying analogies between string theory and nuclear physics.
Stephen Hawking predicted in 1975 that black holes emit radiation due to quantum effects.
