Physics Colloquium: The Fermi-Pasta-Ulam Problem and the Birth of Nonlinear Science

In this talk, David Campbell, Boston University, will review the original Fermi-Pasta-Ulam problem and trace several distinct lines of research that arose from it. Specifically, he will show how a continuum approximation to the original discrete system led to the discovery of solitions whereas a low-mode approximation led to an early example of deterministic chaos. He will close with a brief indication of how the recurrence phenomenon observed by behavior by FPU can be reconciled with mixing, equipartition, and statistical mechanics.
