@Akerai I'm not sure what you mean here - it depends on whether the imaginary component of $\lambda_2$ is greater or less than the imaginary component of $\lambda_1$, where $Re(\lambda_1) < Re(\lambda_2)$

Balarka Sen

@goodnight goddamn boi you're on a roll

Mithrandir24601

Although again, I should mention that I've never looked at chirality of 2 levels, so am just guessing based on what I know of 3 level systems

0celo7

@EmilioPisanty So I'm using \operatorname to get an operator \Hess but it's messing up the spacing:

the bar on the left is too far over

Akerai

@Mithrandir24601

The issue I have really is that if the two numbers are conjugate, I just quantitatively don't see why it should be the leading one.

As in, I believe you, but I am unsure how I would derive it, unless they give me some initial values.

good night

00:08

@BalarkaSen you're not too far down the list :p

0celo7

@BalarkaSen do you have a suggestion?

good night

@0celo7 can you paste your code?

0celo7

`Let $u$ be a harmonic function in an open set of $\Bbb R^n$. Then
\[|\nabla|\nabla u||^2 \le \frac{n-1}{n}|\Hess u|^2,\]
where we are interpreting $|\nabla u|$ as an $H^1$ function \cite[Lemma 7.6]{GilbTru}.`

hmm

it broke

good night

and also the operator definition

0celo7

\newcommand{\Hess}{\operatorname{Hess}}

good night

00:12

uhm

i have an idea let me check it if works first

Balarka Sen

@0celo7 none dude

good night

hmm it's not working but you can just do "\mathrm{Hess}" in the definition instead and add your own spaces like "\,"

that does work

Balarka Sen

@goodnight I can give you some rick and morty level Physics.SE question if you want

I screenshotted and saved it a long time ago

good night

sounds good

Balarka Sen

Mithrandir24601

00:19

@Akerai And... I'm being an idiot again... The 2 level case is of course totally different...

If the eigenvalues are indeed conjugates

good night

@BalarkaSen he'd love this book

Balarka Sen

mmm

v e r y n i c e

Mithrandir24601

It's very possible that the eigenvalues aren't conjugates though (although I'm again guessing based on the 3 level case...)

good night

deleted before I get banned.

:p

David Z

You know deleting a message actually makes you more likely to get suspended

in the sense that it draws attention to your message

good night

00:26

isn't it past your bedtime?

Akerai

Are we both talking about the same thing, having two differential equations of two variables, linearising them at the critical points and drawing the phase portrait?

0celo7

why would anyone get suspended for that @DavidZ

Mithrandir24601

@Akerai Yeah, as I said, the 3 level case is different :/

Akerai

Yeah, the issue I had in two dimensions is that you get solutions of the form $\exp{\alpha \pm i\beta}$ around the critical point.

David Z

@0celo7 For what good night posted? They wouldn't. I'm just saying, in general, if a person posts something which is suspension-worthy and then deletes it, the deletion tends to draw more attention to it, reducing the chance that it just goes unnoticed.

Akerai

00:30

i.e. both have the same radial behaviour, but one turns clockwise and the other anticlockwise

good night

@DavidZ that's false because deleted messages can't be flagged and most 30 min bans are from 10k users and therefore a mod would have to look at the deleted message and ban the individual specifically.

Akerai

and it can happen that the linearised derivative of the system depends only on the quadratic terms of the coordinates, so they have the same eigenvectors.

ah sorry ignore the last sentence, I ran ahead of myself. It's unrelated.

good night

but most of the mods are usually asleep so it's a non-issue :p

David Z

@goodnight Yes, that's exactly what I'm talking about. Sorry, I should have mentioned that I meant manually-imposed suspensions, not the automated suspensions that result from flags.

good night

@DavidZ but it's still false because if the message was bad enough for a mod to do all of that to ban the user it wouldn't go unnoticed in the first place and they would just get flagged as per usual.

Bernardo Meurer

00:34

Flags are an instrument of oppression

David Z

Eh, if you want to ignore my advice, feel free

good night

@DavidZ this is a christian chat and we only take our advice from the lord himself

right @BernardoMeurer ?

Bernardo Meurer

@goodnight That is correct my child, yes

Listen only to the our lord and savior St. Ignucius

enumaris

vim is better

(proceed with flame war)

Bernardo Meurer

@enumaris
1. Vim is an awesome editor, I think Vim and Emacs are equally capable for most uses
2. Don't.

enumaris

00:38

dang, the bait wasn't taken :(

Maybe if I said...Microsoft Word is better.

Bernardo Meurer

@enumaris NOT ON MY CHRISTIAN CHAT

::dips computer in holy water::

enumaris

XD

hmm

good night

linux i meant linux

y'all know tux

Cows

@enumaris you do some ML right?

@BernardoMeurer who is the guy in the picture lol

enumaris

indeed

I'm training a neural net on 1.3tb of data as we speak

Cows

00:43

That's cool

good night

@enumaris is it possible for machine learning algorithms to have autism?

Cows

@enumaris are you doing it for astro? or industry?

enumaris

I think all ML algorithms are autistic

Cows

haaa

enumaris

I'm doing it for my own project

Cows

00:43

whaaaa?

good night

@enumaris oh can they get depressed too

Cows

what algo are you using?

enumaris

don't think so

they are all sociopathic

psychopathic

no empathy u know

The net I'm running is a not fully connected Conv-net

branched conv-net?

Cows

cool!

enumaris

it has batch-norm, and mild L2 and Dropout regularization

Cows

00:45

May I ask what the project is?

if you can share , otherwise it's ok too lol :P

enumaris

it's gotta do with music :D

good night

@Cows why are you making it awkard

@enumaris do you know of any ML algorithms that can recommend you songs with similar characteristics?

Cows

@goodnight dunno? lol

good night

like through their waveform and bpm and not recommend through population statistics

Cows

@enumaris interesting

enumaris

00:48

spotify's discover weekly?

Cows

Are you using any libraries, and what lang are you using?

enumaris

I'm using Keras in Python

Cows

Did you write your BLAS

enumaris

no lol

Keras uses Tensorflow

Cows

hehe

enumaris

00:49

Tensorflow uses numpy

I think

Cows

yeah I asked that question before you said Keras. lol

enumaris

I did write my own neural net using only numpy

took a while

but even then I'm not writing linear alg. equations...that's too basic lol

Cows

I do ML in JS and Haskell

no lib

enumaris

I'll trust the numpy developers to know the fastest way to get a computer to compute a giant matrix multiplication for example...

Cows

but I do basic ML

enumaris

00:50

I see

I'm not familiar with JS and Haskell

Cows

standard neral with back prop

soft act et al too

enumaris

softmax?

Cows

neh I go Relu

Bernardo Meurer

@Cows Richard Stallman

Cows

@enumaris yes hehe

good night

00:51

@enumaris there's a famous ML researcher at my university

geoffrey hinton

do you know him?

enumaris

ah

yeah

I'm taking his course on coursera lol

Cows

@enumaris but I am more of a hobbyist/ occassional paid dude hired to do things lol

enumaris

the came up with backprop I think?

right now I'm purely a hobbyist

lol

Until I can find someone to pay me...

good night

idk but it says he invented deep learning

enumaris

I think he invented backprop

which is like the backbone of deep learning as we know it today

good night

00:53

:p

enumaris

I'm learning RNNs right now

they seem very useful

good night

im gonna learn compsci and ml one day

but today is not the day

enumaris

I'm also re-reading Ballentine and Wald

Bernardo Meurer

ML is a fad

enumaris

gotta not forget my physics heh

well ML has been around since like the 60's...so...

good night

01:08

oops misread urggg am i drunk

w/e

Bernardo Meurer

@goodnight You drink now?

good night

not yet

Bernardo Meurer

Ah, good

be healthy

good night

I only said that to sound cool

i don't even know how it feels like to be drunk

but i have a feeling i'm drunk 24/7 so it's all good

Bernardo Meurer

Tbh I haven't been sober for this long since 2013

Being sober is just horrible, I don't know how I coped

good night

01:11

does blue alcohol exist

if it does make sure i never find out

Bernardo Meurer

Yes

Curacao Blue is a famous one

Akerai

Yes, WKB

lol wait, not WKB

WKD

good night

@Akerai that's only approximately alcoholic :p

Bernardo Meurer

good night

orang!!!!!

that ruins it tbh

Akerai

01:13

hahah :D

good night

y'all need some of this

the real stuff

@BernardoMeurer i thought of a fun idea for your meme

let me make it now

Bernardo Meurer

Lol, alright

good night

the square ruins it

Bernardo Meurer

lol

good night

deal breaker if you ask me

good night

01:38

@BernardoMeurer you there?

Bernardo Meurer

Yeah

good night

how bernardo picks up girls:

5

:p

Bernardo Meurer

Lol

Actually accurate

good night

thanks

today is an unproductive day... feeling too down to do work

i guess I can do @SirCumference too but idk what to do for him

brainstorm time

Bernardo Meurer

Something with not knowing what's going on

Ever

good night

01:50

that's what I had in mind

but I'm trying to think of a scenario where it would be funny

oh I have an idea!

Sir Cumference

Man, I feel so loved right now

good night

<3

enumaris

02:07

learn some physics when you're feeling down

good night

02:37

@SirCumference this idea is taking too long

time to improvise with something quick n dirty

Sir Cumference

02:49

@goodnight think about what you post...

good night

you're right

Bernardo Meurer

@goodnight I'm bothered you didn't use Free fonts on that :/

good night

@SirCumference

Sir Cumference

obe is destroying the starboard

good night

:p

is that what happened last night?

Sir Cumference

02:51

@goodnight I don't get it

good night

...

Sir Cumference

Sigh I hate you...

just hit me

good night

context for ppl out of the loop:

Nov 25 at 6:43, by Sir Cumference

Wow...I dropped my charger plug into a jar of mayonaise

Sir Cumference

Why you have to innuendoize everything I say...

Bernardo Meurer

@goodnight Lol

that is amazing

good night

02:54

ya

MadamAyonnaise is a beauty

i'd do that too but I don't have a thing for mayonnaise

@BernardoMeurer the conversation would go something like this

sircumference: howdy
madamayonnaise: hi do you also go to columbia?
sircumference: im afraid i can't tell you but probably
madamayaonnaise: what do you study?
sircumference: astrophysics
madamayonnaise: that's incredibly cool here's my number 1-800-418-3275
sircumference: thanks want to hear a physics joke?
madamayaonnise: no thanks
sircumference: did you know black holes have infinite succ, that's what holds the universe together and also galaxies

3

:p

Sir Cumference

> im afraid i can't tell you but probably

Bernardo Meurer

Hahahahaha

Sir Cumference

You give me quite a lot of credit :P

Bernardo Meurer

@SirCumference Doesn't go to Columbia; does he?

good night

nobody knows

lol but probably

Sir Cumference

03:08

@goodnight That's completely inaccurate.

A person wouldn't have a 1-800 number.

Only businesses need toll free numbers

good night

it's a jar of mayonnaise...

did you google that number?

:p

Sir Cumference

@goodnight Wow, you put some effort :P

I applaud that

good night

only for you :p

Bernardo Meurer

@goodnight Woah, props

0celo7

@goodnight you turned into a complete memer

how did that happen

Bernardo Meurer

03:13

@0celo7 He's an artist

8 hours ago, by Phase

ACuriousMind: --h bar has been moved to trash--

good night

@0celo7 percocet

2

Sir Cumference

@goodnight You even made me say howdy

You did your research

0celo7

@goodnight I love it!

Sir Cumference

Who keeps starring?

0celo7

You're a new man

Bernardo Meurer

03:16

@0celo7 This is how much you can improve if you convert to Christianity

You can become a memelangelo

good night

@0celo7 ::blushes:: thank you senpai

Bernardo Meurer

Making true masterpiece memes

Like leDavid

good night

@BernardoMeurer ya damn straight

i specialize in abstract art

Bernardo Meurer

@goodnight Make a Ryan meme

good night

Bernardo Meurer

03:21

Hahahahaha

DO ET

good night

I have some funny ideas using 2015 Ryan meta

most people here won't understand them though, but 0celo7 will and then i'll die for it

0celo7

@goodnight revealing private messages is a very good way to get yourself on a permanent ignore list.

Bernardo Meurer

@0celo7 Why didn't you just claim it as being photoshop

good night

lmao is that a confession

0celo7

no

good night

03:24

are you a liberal?

0celo7

of course

good night

also I wouldn't ever reveal anything sensitive. this was just a funny thing :p

calm down bruh

inb4 sarcasm

didn't know dwarfed kittens had an ignore list

:p

BEFORE YOU DESTROY ME PLEASE JUST RELAX AND TAKE A DEEP BREATH I BELIEVE IN DIPLOMACY

0celo7

::places hand on Nippon steel::

I think he is too powerful...

good night

that entirely depends on how many pheonix downs you have right now

0celo7

over 9000

Abcd

03:46

@goodnight who is the person with the cubes as his profile pic?

Sir Cumference

04:00

@0celo7 what 9000

0celo7

@SirCumference your [redacted]'s weight in oz

Cows

Watching fantastic four

Cows

04:34

Guys get on FX, Fantastic Four is on!

good night

@Abcd they call him zero

he dispenses the cubes

we should all aspire to be like him someday

0celo7

04:47

@BernardoMeurer I need to do fortran, halp

good night

@Narcissusjewel hello

@Narcissusjewel i'm sorry for accusing you of flags against humanity

@Narcissusjewel I made this for you so you don't feel left out. here in the h bar we include everyone and that's everyone in the cube queue on the top right.
