Shout out to the euler relationship for allowing me to forget every single trig identity I ever learned
I’d be curious how that works? I always hated memorizing those things, and I’d love it if there was some way to easily derive those from a single relationship.
e^(ix) = cos(x) + i sin(x)
That is the euler relationship. You can use that relationship to convert any expression with a trig function into an expression of exponentials and imaginary numbers. “Euler’s formula” is a good search term if you want to learn more
I don’t know what any of those are, but surely lagrangian mechanics was invented by Lagrange, right
I guess Euler-Langrangian mechanics was too much of a mouthful!
An old bit of wisdom: “Most scientific concepts are named after the second person to discover them”
hmmm… I was going to go with continuum mechanics as that seems made up. Maybe Euler contributed something to Lagrange.

Continuum mechanics deals with deformable bodies, as opposed to rigid bodies.
I guess F = ma is pure Newton + Galileo + Kepler + a bunch of people that weren’t Euler.
