This theory is widely accepted as a fact today. But Bates didn’t think that focusing depends only on the lens changing shape.

Webb1 nov. 1976 · Theory of glasses: S. F. Edwards one is the mean field of the Weiss theory of ferromagnetism. One assumes that such a field exists and calculates the value which makes F a minimum. For T> Tc the mean field is zero, and the material paramagnetic. For T< Tc the mean field is non-zero, and saturates as T -* 0 to the value ob- tained when … Webb6 apr. 2024 · Towards understanding glasses with graph neural networks. April 6, 2024.
