Having a bit of a brain-fart. If I'm given force maginitude at distance for couloumb's law and point charge, how can I get maimum force magnitude?

@ACuriousMind No physicist lawyer cougar for me :(

listofthingineverthoughtidsay++

You're growing up :)

@0celo7 How did it go?

Seems I missed a fight or something.

for me it showed 2400 unread messages

@BernardMeurer just got back

Baby got back?

uhum

@KyleKanos she does

That would be awkward if she didn't.....

@KyleKanos Let us see your handwriting

Uh. Why?

^

It's a competition, who has the worst one

Currently @0celo7 is champion

Eh, mine's okay.

wtf

It's legible. Mostly

Mine's in the transcript somewhere

actually no, @FenderLesPaul's one might be worse

I thought @Danu had the worst

Was it Danu that tried to summon Cthulhu on the board?

You guys do weird things here

oh no that was FLP

Yeah his is the worst

FLP?

FenderLesPaul

Ah

Friendly Little Pony

Not being here, acronyms are lost on me

Really KK, really?

Well, when they're about people.

I'll get ACM to FLP your JD

I know ACM! I know that one!

I presume JD is Duffy?

Yep

Goddammit we need more acronyms

I learn lots of new things at the Jaerb

Jaerb?

homestarrunner.com/cantsayjob.html

Probably before your time

The hell

hahahaha

I'm 17, most things are before my time

I think I was in early undergrad when that was popular

@ACuriousMind Ok, so the key theorems are the following: Theorem 1. Let $\omega_g$ be a volume form and $\{E_i\}$ be an orthonormal frame. Then $\omega_g(E_1,\dotsc,E_n)=1$ iff $\omega_g=\sqrt{g}\,\mathrm{d}x^1\wedge\cdots\wedge\mathrm{d}x^n$. Theorem 2. If $\iota:S\hookrightarrow M$, $S$ has codim 1, then $\iota^*(i_X\omega_g)=\omega_{\iota^*g}$. Unfortunately, I don't see where exactly in Lee he uses any property specific to Riemannian manifolds...(as opposed to pseudo-Riem.)

(that being Homestar Runner)

OMG

THIS IS GREAT

I'M CRYING

@0celo7 You'd be proud: some of the documents I write at work use $\mathrm{d}x$ for integrals and derivatives

Instead of being lazy and using $dx$

I also managed to use the term group isomorphism to describe an attribute of $\ln(x)$

@KyleKanos Holy shit how

@KyleKanos :)

Homestarrunner is life

@0celo7 Because $(\mathbb{R}^+,\times)\mapsto(\mathbb{R},+)$

And I used $\ln(a/b)=\ln(a)-\ln(b)$

@KyleKanos Oh, are you sure you don't mean homomorphism?

You just turned the plus sign there man, quit cheating

@0celo7 No

Oh, is $\mathbb{R}^+\cong\mathbb{R}$?

Yeah, they have the same cardinality.

Sigh, I really want to learn maths

If I'm not mistaken, the $\mathbb{R}^+\to\mathbb{R}$ is the homomorphism aspect, but the group of positive real & multiplications to real & addition bit is the isomorophism

@BernardMeurer I also removed a plus sign too

@KyleKanos Right but I don't think that two groups can be isomorphic unless they're isomorphic as sets.

Heck if I know....

Now it's not even cheating, it's just magic @KyleKanos

But we haven't gotten close to groups in my algebra lecture, so all I have is conjecture.

And bijecture

:D

@BernardMeurer I can recommend a book.

@0celo7 Please do, will it be understandable tho?

I'm willing to put hard work into it

@BernardMeurer Introduction to Smooth Manifolds by Jack Lee.

Which is something I don't even do for my survivel

Hitchhikers Guide to the Galaxy

He reviews calculus in the back.

Implicit function theorem, PDE stuff, the basics.

Options, Futures and Other Derivatives by John Hull

@KyleKanos I stopped reading fiction, it caused me to daydream

@BernardMeurer Seriously, if you ever get into geometry, pick up a copy of Lee.

Because you're not ACM and can't remember every proof.

The prices on these books

He has most of them in his book.

ouch

@BernardMeurer I got mine for $25.

Yeah but 20$USD is a lot of Brazilian monopoly moneys

I sat near some Brazilians when Jose Aldo got KTFO

That was rather amusing

@KyleKanos Yeah just finish making me sad man, REAL NICE

Almost as funny as Anderson Silva shattering his leg in his first fight after getting KTFO for being an idiot

Every day it's a new 7x1

I'll go back to my corner

Sorry.

I'll stop

I'll be heading off to bed soon anyway

Working 12 hour days (commute included) kinda sucks

Working 7 hour days (not including commute) sucks too

At least you guys have a job

Well you're probably making close to minimum wage, no?

@KyleKanos Si, $11/h

@ACuriousMind IT FOLLOWS FROM THE MINUS SIGN IN THE METRIC

You follow the minus sign

I CRACKED THE CODE

I'm glad I'm not making $11/hr

Me neither

But I ain't glad

I couldn't afford the wife & kids

@KyleKanos I'm glad I don't have your kids.

I'd have to sell them for science or something

Kidneys.

@0celo7 My kids are awesome

@KyleKanos Kids?

You have what, like five kidneys at your disposal?

4 kids

@KyleKanos WILL BABYSIT FOR MATHS

Yeah, they're like 6, 4, 2 & 2 years old

They're not really ready for maths

And I can teach them

No no

You'll teach me

@KyleKanos what math do you know

teach them Riemannian geometry first

on surfaces

it's intuitive

Practical math: 2+2=5

@BernardMeurer btw it went well

@0celo7 Good thing

@KyleKanos Ah, give them 1984 right off the bat.

Was her mother a zealot after all?

No, she's super nice

I wish I had a pocket mathematician

Did she allow you to perverse her daughter?

@BernardMeurer no, @ACuriousMind is mine

@BernardMeurer the fuck

@0celo7 I concur...that was awkward

@KyleKanos It's what he'll do

Crystal crusher

Occy don't know jack about girls

Occy?

Ocelot

@KyleKanos my nick is Ossie

No, your nickname is either 0celo7 or Occy

Your real name is something else

@KyleKanos Ryan

His real name is John

I know what your real name is

He's lying

my real name is

dammit

JOHN CENA

Your email last month has your full name in it

HAHAHAHAHAHA

@KyleKanos Stalker

@KyleKanos my full name is not a secret

@BernardMeurer has met my sister

@BernardMeurer He emailed me

@0celo7 True

I had drinks with her

Would any of you trade books for my organs?

I don't think I've met anyone

And I think that is a good thing or something.

@KyleKanos Really? Not even your wife?

me ^

@BernardMeurer Nope. Somehow managed to have 4 kids without ever meeting her

@KyleKanos TEACH ME

It's actually quite difficult

@KyleKanos gloryholes are fun

Does she even know?

but you know about that ;)

Oh no @0celo7 You didn't

You dawg

Well, now that that joke was killed by two teenagers...I was meaning I've not met anyone from PSE

Hey hey, it wasn't my fault

@KyleKanos you're gonna have 4+ of us running around in a few years

@BernardMeurer Yes.

@0celo7 No, they'll be 4 of me running around

Very different

@KyleKanos Won't make it past his kids' teenage years

@KyleKanos So you were better than us?

@BernardMeurer check snap, my first offer

Oh, now I get it

@0celo7 Probably

I want introductory books

@KyleKanos Define "better"

Didn't make sex jokes?

@BernardMeurer bro it says INTRODUCTION to String Theory and M Theory

Isn't string theory kind of broke?

Like my morals

Well I'm heading to bed now

I have to have some introductory shit around here

g'night folks

@KyleKanos Really?

I don't even make them that much anymore

@KyleKanos Have a goodnight man

@BernardMeurer I don't think I have anything here you could read :/

maybe Weinberg if you know some calculus

or Shankar

I know some calc

vector calc in n dimensions?

Nope

@BernardMeurer that's an issue

See, I need MATHS

so learn vector calc

maybe you can learn concurrently with @KyleKanos 's youngsters

@BernardMeurer once you know vector calc there are many many options for you to explore

@0celo7 Sigh

@BernardMeurer stop sitting in your room doing whatever you're doing and go learn vector calc

@0celo7 Give me a pdf

I don't have a vector calc pdf

And I'm searching for a job currently

vector calc for dummies

vector calc is trivial, why would I have a PDF for that?

Dunno, some larger book that went over it as well

no

FIND ME ONE

"an event is starting in 7 minutes"

what event is this

Was about to ask

@user507974 not for this room. The next scheduled event is a chat session on March 8.

@BernardMeurer have you watched the MIT calc 3 vids

@0celo7 Nope

@user36790 I'm too worried about orientations on Lorentz manifolds to care

I don't know what that is

yes

you mean an eigenstate?

then why don't you say the standard word?

@user36790 my naive understanding is that it only works if $|x\rangle$ are eigenstates of $\hat Q$

@user36790 that's definitely not normal

@user36790 ok, leave that as a comment
