Many years ago I had the great pleasure of being in Henry Moore's home and studios. Fortunately for me he was in Paris at the time and my wife and I got to spend a couple of hours with one of his sculptors. He showed us how the monumental metal sculptures were made as well as taking us into Moore's study where he kept the stones, bones and other found objects from which he got his inspiration. He was keenly aware of form as I suspect Weston was. I have also seen many vintage Weston prints and don't think either artist was really concerned with mathematics or physics. They more likely were extremely talented artists who greatly appreciated and saw beauty in the forms most people pass by every day without noticing.
