| The '''Fermi-Pasta-Ulam experiment''' <ref>[http://lib-www.lanl.gov/cgi-bin/getfile?00353569.pdf Enrico Fermi, John R. Pasta and Stanislaw M. Ulam "Studies of nonlinear problems I", Los Alamos Scientific Laboratory Report '''LA-1940''' (1955)]</ref> consisted of a one dimensional system composed of 64 particles, whose ends were fixed, and the particles were connected by a selection of forces; quadratic, cubic, and "broken"-linear. Their main finding was that there was an apparent lack of [[equipartition]] of energy amongst the available [[Degree of freedom | degrees of freedom]], even after as many as 10,000 cycles on their fast electronic computing machine (MANIAC I).
