Fermi–Pasta–Ulam–Tsingou problem

The Fermi-Pasta-Ulam-Tsingou (FPUT) problem is a significant concept in the fields of statistical mechanics and nonlinear dynamics. It originates from a famous computational experiment conducted in 1955 by physicists Enrico Fermi, John Pasta, Stanislaw Ulam, and Mary Tsingou. The experiment aimed to explore the behavior of a system of oscillators, specifically focusing on a one-dimensional chain of particles connected by nonlinear springs.
