 American string theorists

"American string theorists" refers to physicists and researchers in the United States who specialize in string theory, a theoretical framework in physics that aims to reconcile general relativity and quantum mechanics. String theory posits that the fundamental constituents of the universe are not point-like particles but rather one-dimensional "strings" that can vibrate at different frequencies. These vibrations correspond to different particles, and the theory seeks to describe all known fundamental forces and particles in a unified manner.
