Polchinski was the subject of a running gag on an episode of The Big Bang Theory. In the episode "The Paintball Scattering", Sheldon would choke up and be unable to respond every time anybody asked if the paper on super-symmetry, which he had recently published with his wife, Amy, was derivative of the work of Polchinski.
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.
In formal language theory, weak equivalence of two grammars means they generate the same set of strings, i.e. that the formal language they generate is the same. In compiler theory the notion is distinguished from strong (or structural) equivalence, which additionally means that the two parse trees [clarification needed] are reasonably similar in that the same semantic interpretation can be ...

A diagram of string theory dualities. Blue edges indicate S-duality. Red edges indicate T-duality. Up until the mid 1990s, physicists working on string theory believed there were five distinct versions of the theory: type I, type IIA, type IIB, and the two flavors of heterotic string theory (SO(32) and E 8 ×E 8). The different theories allow ...

In fact, a theory with large R and a theory with small R are equivalent, where the role of momentum in the first is played by the winding in the second, and vice versa. Mathematically, taking R to / and switching n and w will yield the same equations. So exchanging momentum and winding modes of the string exchanges a large distance scale with a ...
