What is recorded here?
Used numerical experiments on a nonlinear oscillator chain to test energy sharing among modes and observed unexpected recurrence rather than the anticipated rapid approach to equipartition.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The record is Los Alamos report LA-1940 of May 1955. Later FPUT analyses, soliton theory, chaos thresholds and broad claims about the first computer simulation remain separate.
