it's it's called a gives distribution in the general case where the energy function is complicated this normalizing turn normalization term is intractable you can't compute this integral so you can't actually turn the energy into into a probability and that's why I'm arguing for just manipulating the energy function now going to a density because you can't normalize it you can only normalize when the energy is kind of has a trivial form and it's not that interesting so right so that's the Department of Energy
