EDIT: My barbaric/peasant state of intuition says that K is more like a differential equation (Maxwell's equations) but S is more akin to the "integral form" (Jefimenko's) Note how the People feel like they understand M but for J they feel at least a bit of wariness.. And thanks for the JCS quote, it does feel relevant to the struggle to even design useful quantum computers Going back to mulling the Lagrange multipliers now :) Pace Darwin, the anglo geniuses seem generally trigger happy -- not good for HN idolatry (up to and including the manPG) (Grassmann vs Hamilton, if you want to visit that general topic) (JM Keynes vs..?)
