@JohnRennie OH MY GOD THEY WEREN'T LYING ABOUT WASHING HANDS BEFORE GOING TO THE BATHROOM IF YOU TOUCH FRESH HOT PEPPERS

@Slereah is it?

It is one of Those papers

With principal bundle connections

"The book that comes closest is the classic reference [28] by Steenrod."

Can't escape it

(no one has read it)

It's just comforting to know that it exists

Somewhere, all the fiber bundle stuff is explained

The world makes sense

@JohnRennie it's in my nose too

@Slereah I'm doing algebra

it's awful

trying to compute traces of representations

I'll bet

mmm, character theory

it's actually the worst form of math @Semiclassical

i'll admit, i've avoided having to ever deal with it

In a probably vain attempt to ask a fourth question: How would you describe an apparent westward force in a co-ordinate frame fixed to earth that appears if you were to jump?

Because if you jump, or do anything where your horizontal velocity is unchanged, you're gonna lag behind theoretically by some amount, but how does one go about introducing fictitious forces for things? What's the standard method?

Coriolis force

Oh, coriolis force accounts for that too?

Yes

There's only really 4 fictional forces, for the most part

The linear acceleration kind

Centrifugal

Coriolis

and Euler

@Semiclassical there are tricks, but implementing them feels worse than pulling teeth.

Like you get this fucking group, then have to compute the center and commutator subgroups, then quotient them to get reps on the quotients, which are hopefully simpler

That comes out of just differentiating vectors right?

secondary question

actually nvm

ty

@Semiclassical and there's no tricks for that, you have to compute ALL of the damn commutators and whatnot to see what works

@Slereah can I re-ask a question to you that I asked h bar earlier?

Just to check one single thing

@0celo7 ew

can an observer experience proper acceleration constantly, for any amount of time, according to relativity?

Why are spinors so hard

@bolbteppa I hope there's a punchline

@Semiclassical Aha my group has abelianization $C_4$ and we worked that out in class

nice

::searches frantically in notes::

@Semiclassical and the quotient by the center is $S_3$, I think, which we also did

now I just have to figure out how the pullback reps line up exactly

@Semiclassical I took this class to learn more algebra

I have learned more algebra, and have learned enough to know I don't like algebra :P

loool
