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.
