Their studies were first described in Los Alamos Report LA-1940 May 1955 LA-1940 Page 4 " We have, therefore, a dynamical system of 64 particles with forces acting between neighbors with fixed end points. If x i denotes the displacement of the i-th point from its original position, and α denotes the coefficient of the quadratic term in the force between the neighboring mass points and β that of the cubic term, the equations were either¨x
