Infinity's Trivia Thread

[infinity.]

we're all nerds to some extent here. why not play some trivia?
if someone wants to put credit bounties per question, i'll reciprocate, but for now it's just for funzies. when someone gets it right i'll write another one.

don't google the answers yo

The C major “Fabel” piece in one of this man's works breaks the D-flat major/F minor pattern used to describe Eusebius and Florestan, members of the “League of David,” a completely insane group of this composer's imaginary friends. A piano virtuoso from an early age, this composer's playing career was ended prematurely due to a hand injury. In his most famous 3rd symphony, the fourth movement depicts an Episcopalian coronation. This composer spent the last two years of his life in a mental institution and attempted suicide multiple times. Name this composer, the husband of Clara Wieck and composer of the Rhenish Symphony.

Edit: If you do happen to google these, note, these are questions or parts of questions I wrote.

Wow, I did not know all of this stuff about him. That's pretty cool.

(I had to google the answer)

time elapsed. the answer was Robert Schumann.

next question:
This quantity’s interactions are described by the Russell-Saunders coupling scheme. In quantum mechanics, its expansion in uncoupled bases requires Clebsch-Gordan coefficients. One result about this quantity follows from the directional symmetry of space, according to Noether's theorem. A consequence of that result is the fact that a line drawn from a planet to the sun sweeps out equal areas in equal times. Defined as the cross product of the position vector and its linear analogue, this quantity is conserved in the absence of an external torque. Name this rotational quantity, the product of moment of inertia and angular velocity.

This one's pretty easy: angular momentum.
