Packet 8: Bonus 21
This physicist used the MANIAC computer to program one of the first numerical simulations, where she showed a vibrating string with a nonlinear force law behaves quasi-periodically. For 10 points each:
[10h] What physicist was credited in a footnote, but not listed as an author, on Fermi, Pasta, and Ulam’s paper describing that vibrating string?
ANSWER: Mary Tsingou [or Mary Tsingou Menzel]
[10m] Tsingou’s result surprisingly disobeyed this statement, according to which all of a system’s microstates will be accessed with equal probability over a long period of time.
ANSWER: ergodic hypothesis
[10e] The FPUT problem was a foundational result in the theory of systems with this property. The behavior of nonlinear systems with this property strongly depends on their initial conditions.
ANSWER: chaos [or word forms like chaotic; accept chaos theory]
