I don't know if I made a great or poor life choice in deciding to take a quantum mechanics course while having no classical mechanics background, but it's been taking up a significant portion of my time, so I probably won't be able to write for a long while. On the other hand QM is absolutely fascinating.
About Me Not certain what information about me would be useful here, but here are some generic profile details. I'm an undergraduate at a time-devouring university. I'm agender. I enjoy theorizing about fictional worlds way too much for it to be healthy. My native language is English, I guess, or Shanghai Chinese, I speak embarrassing Mandarin Chinese and passable German, and I am learning Russian and ASL - I like understanding what people say, and I should probably learn French but I keep putting it off for some reason.
Math Corner In pointless relevance to my pen name, here are some useful results produced by and/or named after Augustin-Louis Cauchy, along with some really crappy descriptions. By no means complete. Disclaimer: I am not a mathematician, I just hobby math. Also, I am happy to have finally signed up for complex analysis, and to finally have learned about a lot more things that were named after Cauchy.
The ones I actually know about:
Cauchy-Schwarz inequality - That really handy thing where the inner product of two variables is less than or equal to the product of their magnitudes.
Cauchy (sequence) - A sequence is cauchy if the elements get closer and closer together, and only a finite number of elements are more than a certain distance from one another.
Cauchy distribution - A distribution with fat tails, which has no mean or variance (I think it does have fractional moments less than 1 though). Its density function is something like 1/pi times the integral of arctangent. I do not currently know what it is useful for beyond that these are important things in physics.
Cauchy principal value - A fancy name for when you try to do an undefined integral by hedging around the undefined spot with limits and changing up the limits of integration with epsilons.
Cauchy-Riemann equations - Equations relating the partial derivatives of the real and imaginary parts of analytic complex functions. They are helpful.
Cauchy integral theorem (aka Cauchy-Goursat theorem) - Integral of an analytic function over a closed loop in a simply connected domain is 0. Leads to awesome cool simplification of integration.
Cauchy integral formula - A formula relating integration to differentiation . It is super amazing and provides great new ways of looking at old integration problems that used to be horrible.
Cauchy bounds - following from the integral formula, bounds on the value of the derivative of an entire function.
Things I don't know about but have heard of (now only is one thing):
Cauchy condensation test - A useful test for convergence that I never learned and which probably would have been good to know while I was dealing regularly with infinite series. Has something to do with checking the convergence of a "condensed" version of the series which is difficult to describe in words.
