You may not be facetious, but you are being condescending by implying that I have never read a math textbook, or that I have made no attempt to find this information. In fact, I have read fairly extensively about elliptic curves and I have never seen any source that describes the history. To the contrary, many sources say that elliptic curves have nothing to do with ellipses, but this series of tweets seems to imply that this isn't true. So if you want to point me to an actual source, that would be much appreciated. But all you have to say is RTFM then my response is STFU.

You're meant to pick up the history as you learn the techniques. You're supposed to learn about Galois when you study groups, Cardano when studying complex numbers, etc. We explicitly invoke the names of mathematicians not to try to summon some saintly Great Men, but to imagine their mindsets and how their various discoveries fit together. Directly examining your textual argument, it's not possible to learn about elliptic curves without learning at least a tiny fragment of the history, where one of Weierstrauss, Montgomery, or Edwards has had their name directly associated with the concrete representation of the equation defining a curve.

I'd like to think that I'm pretty good with elliptic curves, given that I explain them to other folks. However, this tweet-thread still showed me things that I didn't know about the history of maths. Some of these tweets directly led to minutes (hours) on Wikipedia and chasing down various PDFs to read.

Honestly, you could stand to be less self-aggrandizing. It's okay if you don't get every joke immediately; you don't have to know every bit of historical background.

Elliptic curves aren't interesting because of the answers that we have. They're interesting because of the questions. One open question [0] is on the Millennium Prize list. Another open question is almost never written down because it's so simple; "why 1728?" [1] Coming to understand these questions is the goal of our entire process, so there's not much that I can really do other than to ask you to join the process of exploration.

I think you are over-reacting. I didn't read mhh__'s comment as directed at you specifically. It's more of "When in want of X, go read a book on X".

One detailed discussion of elliptic curves with lots of history is: https://www.maa.org/sites/default/files/pdf/upload_library/2...

To answer your specific question: "Elliptic curves have almost nothing to do with ellipses at all. Why then are they called elliptic curves? The answer lies in the word almost. There is a connection between ellipses and elliptic curves, but it’s not at all obvious and is the result of a connected but distinctly nonlinear sequence of mathematical events."
