The Terrible Truth About Dreidel

^ really good

CooperCape

Oh my word there's secret hats...

Emilio Pisanty

@CooperCape well, to a point

CooperCape

hmmm/

Or is there only one 'secret' hat...

Emilio Pisanty

@CooperCape oh, no, there's plenty

CooperCape

I'm looking at the list...

A: Winter Bash 2017 Hats

Secret Hats Ooh, Shiny! Cosmic Brain Galaxy Brain Universe Brain Rep Cap

CooperCape

Ahhh I see

Emilio Pisanty

@CooperCape the complete list, or the intentionally-incomplete list?

;-)

CooperCape

Ahhh the latter

Complete list ruins the secrety fun

Emilio Pisanty

though "we give you a hat if you get a Good Answer badge" loses some of its luster if the system takes aaaaaaaaaaaaaaaages between an answer getting 25 votes and the badge getting awarded

CooperCape

Specially when they disappear in Jan

Also isn't that a bummer if you've already got the badges?

Emilio Pisanty

8:14 PM

@CooperCape yes

though high rep has its perks too

CooperCape

Yeah true

I'm still on basic boi rep but I don't do much anyways I just chill

Also just leartn there's an IOS app

@Bernardo mystical lo-fi greetings

Curio

Is there a formula which connects torque with angular velocity?

Anonymous

@Curio Yes

Semiclassical

8:52 PM

if you consider the translation equivalent of that, you're asking if there's a formula relating force with linear velocity. and there is---at least, there's a relation between the net force on an object and the rate at which velocity changes...

@BalarkaSen Crapola. He told me not to do embedded folds like in Milnor and GP. That means I now need a Riemannian metric for the classification.

Balarka Sen

Ugh

well

you could do

Morse theory :D

0celo7

@BalarkaSen GP's proof is by baby Morse theory, yeah?

Balarka Sen

Yeah I think so

Or, well, you can assume triangulation :D

0celo7

Morse functions require Sard, which he's gonna do in the second week.

Balarka Sen

8:59 PM

then the proof is combinatorics

Gross.

:DDDD

lol

Riemannian metrics seem believable enough on 1-manifolds

Hmm. Wonder if they did partitions of unity

@BalarkaSen The issue is that I need to look at two charts of the 1-manifold whose derivatives have the same "length"

for embeddings it's easy because of the induced metric

Curio

@Blue and what is it?

@BalarkaSen urgh this is a complete pain in the ass now

Q: Why not a tag 'Physics-Misconceptions'?

A major part of truly learning any discipline is weeding out the misconceptions that were either planted by others early in life, assumed 'facts', or poorly taught concepts. The matter of of correcting misconceptions in physics, I believe, is highly important but I was surprised that a tag does n...

@BalarkaSen yo

are there any proofs of Poincare-Hopf that don't require some massive machinery?

I know three of them (GP, Bott Tu, Milnor)

Q: Having trouble understanding how to stay on topic

I have a question about my Physics Stack Exchange post: What governs the temperature rise inside an oven? I find myself frustrated with how questions need to be asked... and the pit of 'On Hold / Closed'. I asked a question to understand and learn about a problem Id like to, even if only o...
