Earlier this year we were talking about Kepler’s laws, and I had some seemingly stupid idea about how to make it less easy to understand. This purportedly bad idea grew into a whole paper: https://github.com/bradklee/Dissertation/blob/master/Prelude/Prelude.pdf (The in-line reader does not always work, but “download” does) Most notably, section VII contains a short proof, less than a page, for certifying the ODE of EllipticK (in Cartesian coordinates). I have not seen it, or anything like it, so maybe it is new. There are other interesting ideas in there, including a tabulation of Core results, the definition of “Hotaru mirabilis” (not mentioned at all in OEIS, completely excluded), and a simplification of the proof of Legendre’s relation, compare with: https://math.stackexchange.com/questions/701515/proving-legendres-relation-f... This is not exactly self-promotion, but more of a call to the naysayers. If they have any rational reason why it shouldn’t be published, they could say so now! I am thinking of putting it up on arxiv with tags for physics and algebraic geometry, but I am sure that would ruffle some feathers. So, any thoughts? —Brad
