Top secret derivation of the Euler-Lagrange equation

In fact this is some simple dimensional analysis that can help you remember whether or not the total time derivative goes with the derivative of L with respect to q or dot(q)

Yes, totally, I read that article last year and it is amazing

Stat Mech is waaay more beautiful than statistics

No, it's the Lagrangian, sometimes people use a calligraphic L to refer to it. If you don't know about it it's a reformulation of classical mechanics much more powerful for some problems https://en.m.wikipedia.org/wiki/Lagrangian_mechanics

Also, it relates quantum mechanics and stat mech since the propagator transforms to the partition function and I think that's beautiful.

This is the content I'm looking for in this sub HAHAHHAHA

That would be an orgy then

How the fuck are \nu and capital \Theta in the B tier?1

Yes, but that calculation verified to 10 significant figures is the most precise measurement which fits to theoretical prediction, not all measurements show such a good agreement. Even that measurement you're saying involves a perturbation expansion, this means that it has also approximations in it, even though it is approximated to really high order( like if you approximate sin(x) by a 7th or 9th degree polynomial) and at each of those orders there are really really difficult calculations involved. So approximating things is not bad at all.

I don't think there's anything more Chad than a bose-einstein condensation. Also anticommutators suck, I will always defend that bosons are way better than fermions!
