@BalarkaSen lol so youre a big snoop dogg fan eh? riiight have heard about him and his ... music (1 random google result, 1d ago) o_O :P fortune.com/2018/04/18/…

Balarka Sen

i like that one song

0celo7

@G.Bergeron the guy is the main player in three fields (dissipative equations, random matrices, analytic number theory), and a big guy in basically every other field

G. Bergeron

@0celo7 I read a few of his blogposts when they where closing in with physics.

Balarka Sen

Tao is 2 good

G. Bergeron

5:23 AM

Otherwise I don't usually read papers in any of the fields you mentionned

@BalarkaSen Well, that's great

0celo7

dissipative equations are one of the few interesting aspects of physics

G. Bergeron

@0celo7 I'm all in algebra

There's plenty of algebra in physics

0celo7

probably the worst aspect of physics, sorry

Balarka Sen

are you into spin representations of Lie groups or whatever the shit

G. Bergeron

5:24 AM

@0celo7 I think the converse :p

0celo7

lol Salamon has a new functional analysis book

vzn

@BalarkaSen how about california girls with katy perry? classic + luv video o_O :P

Balarka Sen

Orly

G. Bergeron

@BalarkaSen Stuff like that, but mostly hopf algebra, quantum groups, etc. all applied within the context of integrable systems

0celo7

oh nice, a collaborator of one of my profs has a new book coming out on NS

I should probably get it

Balarka Sen

5:26 AM

@vzn only plebs listen to modern popular music

G. Bergeron

@BalarkaSen To be fair, Snoop Dogg is popular music in my books. :p

Balarka Sen

but he isn't modern!!

Snoop Dogg is 90s rap

G. Bergeron

@BalarkaSen You're just getting old :p

vzn

← kissed a girl & liked it :P

Balarka Sen

I think he released a new album or something that everyone panned

0celo7

5:27 AM

kissing girls is really unmanly tbh

vzn

wtf!

G. Bergeron

@BalarkaSen Or maybe I'm getting old, and it still seems modern to me...

@0celo7 Yeah kissing guys is the new manly

vzn

← outta here now! o_O

G. Bergeron

@0celo7 LOL

Now I lolled at (removed)...

0celo7

was me

Balarka Sen

5:30 AM

no vulgar expressions in my Buddhist channel

0celo7

not some flagging troll

G. Bergeron

Also, why do I always start to cook around 1h00 AM

Balarka Sen

@G.Bergeron I'd listen if you want to explain how the context of integrable systems play out

G. Bergeron

@BalarkaSen Well we study and classify algebraically the physical models that can be solved exactly

In that context, all the analysis is a realization of the algebraic structure behind integrability. But you can always see it reversed :p

Balarka Sen

It'd be nice if you have a toy example for that

G. Bergeron

5:33 AM

@BalarkaSen An actual explanation involving Lax pairs, Yang-Baxter equation all the bells and whistle is beyond what I can do efficiently when cooking

@BalarkaSen The harmonic oscillator

Balarka Sen

So what does one mean when they want to "study and classify algebraically" the dynamics of the harmonic oscillator?

I know the analytic part but not the algebraic counterpart

G. Bergeron

The problem can be encoded algebraically (Weyl algebra) and then solutions are found by studying representations of this algebra within some constraints from physics

Balarka Sen

Huh

0celo7

night

Don’t burn down the room with this algebra

G. Bergeron

For instance, if one is working with a quantum system, then one is looking at positive discrete series representations

Balarka Sen

5:36 AM

gnight

G. Bergeron

@0celo7 Like you don't with your chains and cochains

Balarka Sen

we just need to keep vzn from trashing it with crack physics

and its all good

G. Bergeron

Actually chains are too algebraic for your taste, maybe :p

0celo7

Oh if you saw the analysis that was behind the algebraic topology

You’d be horrified

Just wait until my thesis is done

vzn

← lol crack physicist :P

G. Bergeron

5:38 AM

@0celo7 Yeah it has its unchallenged uses even in QM

0celo7

This analysis is worse

G. Bergeron

Some key results are only known using analytical proofs

0celo7

I’m an expert on that stuff

But this is much worse

G. Bergeron

@0celo7 It's the only kind beyond undergrad analysis I've fiddled with

Oh well, this an a graduate topics classes on entropy

0celo7

Even defining an integer multiplicity rectifiable current takes a month

G. Bergeron

5:40 AM

@0celo7 Have you looked at the work of people trying to make sense of the path integral

I mean when the integrand is not gaussian

As in that case you can just map it to the work with Brownian motion

0celo7

Yes

Just vaguely

Doesn’t seem too interesting

Ok I gotta go, need to be healthy for some Federer theory tomorrow

G. Bergeron

@0celo7 Maybe not mathematically, but having a symbol actually mean something is pretty useful in physics! :p

@0celo7 Cool, good night

Balarka Sen

I'm going to push the whole day and sleep at night

vzn

did someone say entropy? =D

G. Bergeron

@BalarkaSen Like all-nighter?

Balarka Sen

5:43 AM

I already did the all-nighter

G. Bergeron

@BalarkaSen The second one, then

Balarka Sen

I am going to skip my sleep schedule 24 hours forward

G. Bergeron

I mean, is it night for you

Balarka Sen

Nope, day

G. Bergeron

?

vzn

5:44 AM

↑ number theoretic entropy analysis cooked up recently, connected to Collatz

G. Bergeron

Thought you where in the states

Balarka Sen

I am very not in US

G. Bergeron

@BalarkaSen Well me neither, just closeby

Balarka Sen

Ah

G. Bergeron

But yeah after 2 all-nighter, things get weird

So you have a messed sleep schedule too?

Balarka Sen

5:46 AM

Yeah that's bad I only once did 2 all-nighters

Well I go to sleep at 5 AM and wake up at 12 PM

I need to set that right

G. Bergeron

@BalarkaSen I did to submit my master's thesis before taking a plane to the middle of nowhere

Balarka Sen

Urk

G. Bergeron

I hadn't slept for like almost 72 hours at the point

Balarka Sen

I did it experimentally, not out of necessity

G. Bergeron

@BalarkaSen And I used to sleep for 2-4 hours days after days during exam week as an undergrad

It took its toll on my sanity

Balarka Sen

5:49 AM

I can't function without sleep man

G. Bergeron

@BalarkaSen Not many can, but apparently I can. It's horrible, though

Balarka Sen

If I get too little sleep or if my sleep schedule is so bad that I loose all the daylight in my waking hours, I can't think anymore

G. Bergeron

You need to be somewhat stressed out of your mind. e.g. expecting A+ and not having been to most classes in the semester while starting to read the textbook the night before.

Balarka Sen

Lol

G. Bergeron

Humans can think in surprising conditions under stress! :P

Balarka Sen

5:52 AM

I should try this. I have exams in about three weeks, so I'll probably sit down with some stuff and imagine that the exam is tomorrow

That's sure to keep me from falling asleep until night

eulB

@BalarkaSen mad lad

Balarka Sen

\o @eulB

G. Bergeron

@BalarkaSen Oh no no, you have to do nothing until the night before. That raw panic works, I've never been able to simulate it

@BalarkaSen Alas, some people loose it under pressure, so don't take that as an advice

eulB

@BalarkaSen sup nocturne

Balarka Sen

Lol

@G.Bergeron gives bad advises, confirmed

G. Bergeron

5:55 AM

@BalarkaSen Hey its how I went through undergrad! I came out just fine... ish :P

Cows

@G.Bergeron yes, mathematical physicists are usually very smart people. There aren't many American universities pumping out Mathematical physics phd's .

citation needed

@Cows I'm not in the US

Cows

oh

Balarka Sen

5:56 AM

Really though I should get some work done

eulB

@BalarkaSen beautiful

Balarka Sen

Cya on the flipside

eulB

work done is overrated my dude

don't you know work undone is in right now

G. Bergeron

@BalarkaSen LOL

Captain Bohemian

@Cows because American universities focus on engineering more?

G. Bergeron

5:57 AM

@BalarkaSen see you

@eulB Not just not done but actually undone!

as in de-done

Cows

@CaptainBohemian well not sure why, but we do have a lot of theorists I think

G. Bergeron

Ok enough of this blackhole that's this chat for me!

Captain Bohemian

@Cows are you an American? It's like you are from Africa.

I feel engineering is intolerably rough when in conference regarding quantum information.

Dawood ibn Kareem

@BalarkaSen When I was working on my Masters, I got into a cycle where I was awake for 37 hours and asleep for 11. In other words, all-nighters on alternate nights. For months. I don't think any of my friends realised I was doing anything out of the ordinary.

Sir Cumference

So if Lebesgue integration is superior to Riemann integration, why is the latter still taught at all?

John Rennie

6:12 AM

Because Riemann integration is intuitively simple and Lebesque integration isnt'?

Dawood ibn Kareem

@SirCumference Because it's intuitively easier.

snap

John Rennie

:-)

Dawood ibn Kareem

And it's easier to understand why it's kind of the opposite of differentiation.

Sir Cumference

@DawoodibnKareem Well, they aren't really opposites, but regardless

I'm sure Lebesgue integration can be taught in a relatively simple way

Dawood ibn Kareem

@SirCumference That's why I said "kind of". They're "kind of" opposites.

Sir Cumference

6:15 AM

@DawoodibnKareem Fair enough

Ugh, this is bad. I need to finish this assignment by tomorrow and Word won't open

Why is this software so awful

Dawood ibn Kareem

@SirCumference I feel there are too many underlying concepts that you have to grok first before you can get to Lebesgue integration. Whereas Riemann integration is accessible to high school students.

eulB

@G.Bergeron yeee boi
