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). | The '''Fermi-Pasta-Ulam experiment''' <ref>[http://lib-www.lanl.gov/cgi-bin/getfile?00353569.pdf Enrico Fermi, John R.
