Thanks to you and Mike, that's awesome! I wonder what the easiest path is to *learn* the geometric language that you and Mike are using, to the point of following along here? A lot of crypto-interested people can roughly understand RSA and DH, and would like to understand ECC, but get lost with terms like (skimming recent mails): twist torsion homogenous isogenies birational singularities / nonsingular affine projective (plane, closure, line) genus embedding Are there gentle references you'd suggest?
