1943–1959: S-matrix theory. String theory represents an outgrowth of S-matrix theory, [1] a research program begun by Werner Heisenberg in 1943 [2] following John Archibald Wheeler 's 1937 introduction of the S-matrix. [3] Many prominent theorists picked up and advocated S-matrix theory, starting in the late 1950s and throughout the 1960s.

String theory is a theoretical framework that attempts to address these questions and many others. The starting point for string theory is the idea that the point-like particles of particle physics can also be modeled as one-dimensional objects called strings. String theory describes how strings propagate through space and interact with each other.
The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory is a book by Brian Greene published in 1999, which introduces string and superstring theory, and provides a comprehensive though non-technical assessment of the theory and some of its shortcomings. In 2000, it won the Royal Society Prize for Science ...
Fields. Psychiatry, psychotherapy. Friedrich Salomon Perls (July 8, 1893 – March 14, 1970), better known as Fritz Perls, was a German-born psychiatrist, psychoanalyst and psychotherapist.

Clark Leonard Hull (May 24, 1884 – May 10, 1952) was an American psychologist who sought to explain learning and motivation by scientific laws of behavior. Hull is known for his debates with Edward C. Tolman. He is also known for his work in drive theory. Hull spent the mature part of his career at Yale University, where he was recruited by ...
M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995. Witten's announcement initiated a flurry of research activity known as the second superstring revolution.
Acceptance and commitment therapy (ACT, typically pronounced as the word "act") is a form of psychotherapy, as well as a branch of clinical behavior analysis. [1] It is an empirically based psychological intervention that uses acceptance and mindfulness strategies [2] along with commitment and behavior-change strategies to increase psychological flexibility.
