Leonhard euler Memes

The mathematical equivalent of taking a bullet for someone. While math students peacefully slumber, Leonhard Euler stands triumphantly ablaze, having derived multiple notations and formulas that students would otherwise have to create themselves. The man invented so many mathematical concepts they ran out of symbols and had to name things after him twice. Students think learning "e" is hard? Imagine having to discover it.

The mathematical battlefield is brutal. Leonhard Euler, the Swiss mathematician who apparently named half the concepts in calculus, stands heroically blocking a barrage of mathematical notation while math students peacefully slumber. No need to learn multiple mathematicians' names when Euler's got constants, identities, formulas, and theorems covering everything from complex analysis to graph theory. The man's name appears so frequently in textbooks that students can just mumble "probably Euler" on exams and have a decent chance of being correct.
