@Phase Which part of Germany?

Phase

Heidelberg...?

I mean

cough sudo -rf

ACuriousMind

Wrong! I'm not from Heidelberg.

Phase

damn it

0celo7

I know it.

Phase

Guess I'm an AI twin brother of another german

good night

20:01

he's from the rhine

Phase

maybe he'll give me a loyalty card

I've been to somewhere on the Rhine before

0celo7

It rhymes with "zahl"

Phase

I think germans write it Köln

ACuriousMind

@Phase Gotta show a bit more effort there ;)

Phase

It was around christmas time and it was great

0celo7

20:01

and sounds like a famous cough

Phase

the christmas markets were superb

ACuriousMind

@Phase If it has a big cathedral and people drink beer from oddly small glasses, then it's Köln, yes

Phase

@ACuriousMind have you been to Cologne / Köln?

Yeah

The Dom right?

0celo7

oddly small?

they understand moderation

ACuriousMind

@Phase Yes, it's not far from where I'm from

@Phase yup

Phase

20:02

Younger me was a lot more energetic

I climbed all the steps jumping up two at a time

If I did that now I'd die I'm pretty sure

ACuriousMind

@0celo7 No, they don't, because custom is that unless you place the coaster on top of the empty glass, the waiter will automatically bring you a new one when it's empty :D

good night

lol

i jump DOWN the stairs 3 at a time @Phase

and I ONLY fall half the time

Phase

I remember them being spiral for the most part so you must have some Matrix wallrunning skills : P

ACuriousMind

(The waiter will probably also insult you for being a slow drinker in an old-school Kölsch pub)

Phase

German food is so good

Kölsch?

ACuriousMind

20:04

@Phase Adjective to Köln, and also the name of their style of beer

Köln also has a pretty nice chocolate museum

Phase

I didn't try any, I was firmly against alcohol when I went. I'm more lax now but still barely drink it. Does the Beer there stand out against the generic ones? I've never tried a beer so idek what the generic ones are like : P oh yeah I went there

ACuriousMind

@Phase My personal opinion is that their beer stands out by being the most similar to horse urine, but you can find people enjoying it :P

Phase

I cant remember the chocolate museum that well :(

Wow, rude

I'm getting a lot of Nostalgia now

skullpatrol

Waiters insult people for being slow drinkers?

ACuriousMind

I'm a fan of the darker beers, especially Alt from Düsseldorf, Köln's eternal rival

Phase

20:07

I had a souvenir from Köln, was a wooden longsword I brought back, I can't remember where it ended up though

Recommend me a beer and I'll consider buying it sometime : P

Mithrandir24601

@ACuriousMind ... Why have I never been told this before?.. ::books flight to Köln::

@ACuriousMind "horse urine" is a........strange comparison

Unless you tasted it

good night

@Phase founnd

ACuriousMind

20:08

@Mithrandir24601 It's actually very interesting and has a chocolate fountain at the end you can dip biscuits into and eat the result, as many as you want :)

good night

Phase

I am a meme with a sword

You think you can Outfresh me?

0celo7

who here knows nuclear physics

ACuriousMind

@0celo7 you

0celo7

I legitimately have no idea how to do this stuff

@ACuriousMind no, I actually never pay attention in class because I don't care about anything but analysis

Phase

20:09

@0celo7 didn't you spend 3 years on a partially nuclear engineering focused course?

good night

it's simple

0celo7

but I'm danger of failing almost every class now

good night

ya know uranium aka nuclear bombs

0celo7

well, failing one class

good night

plutonium too

0celo7

20:09

but still

Anonymous

@0celo7 JR should know. He used to work for the nuclear energy guys. Also dmckee

Anonymous

anyway...ask your question :P

ACuriousMind

@skullpatrol Köln's people are an odd bunch - they're very jovial but also rather rude. The traditional waiter - the Köbes - will continually tease the guests about their drinking habits and everything else they do. It's part of the experience

0celo7

@Blue I don't know how to do a single problem on my homework, not even where to begin

no one does

Phase

@ACuriousMind I remember going into a really nice restaurant

It was called the Haxenhaus I think, if you go it might still be Nice

Anonymous

@0celo7 Upload it on Chegg XD

ACuriousMind

Nowadays such traditional pubs are rather rare, though.

0celo7

I doubt chegg has nuclear physics

They do I guess

Anyway, try asking here, first

good night

if an atom has an atomic number of 57 and it has 30 neutrons how many higgs bosons does it reciprocate???

it's not on stackoverflow

ACuriousMind

@Blue It, too, is the traditional comparison of people hating Kölsch :P

0celo7

How do I figure out the electron binding energy of an atom for electron capture?

Phase

Ahh such a good piece'o'tune

skullpatrol

@ACuriousMind ...interesting.

ACuriousMind

20:17

@Phase What a horrible night to have a curse...

Phase

ayyyyyyyyyy

Anonymous

@0celo7 Do you know the orbit from which the electron drops? (The captured electron)

0celo7

@Blue I don't know

I am no shit going to fail the class

What the hell

ACuriousMind

@Phase ?

Phase

The reference

Anonymous

20:19

If you knew, you could find the binding energy value from a table. Basically we need some assumption from where the electrons comes. Most probably it's K or L

0celo7

K or L?

ACuriousMind

@Phase I understood it was in response to that, but I don't know what 'ayyyyyyy' means :P

0celo7

I never knew what that was

Anonymous

@0celo7 K shell or L shell

Anonymous

n=1 or n=2

0celo7

20:20

I know, but I don't know what those are

Phase

ayyyyyyyyy is like

ayyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

does that clear it up?

Anonymous

You know principal quantum number I suppose

ACuriousMind

@Phase ayyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy...no.

K is for n=1

Phase

yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyaaa

Anonymous

20:21

L is for n=2

ACuriousMind

You're making me feel old

Phase

:(

Anonymous

@0celo7 Look up charts available online. They have the binding energy for K-shell electrons listed

Phase

@ACuriousMind have you watched this? Dunkey is great

ACuriousMind

@Phase I'm deeply confused by that video

Phase

20:30

That's just a natural part of growing up

"On a quest to save the entire world so here I am playing hide and seek with 8 year olds"

ACuriousMind

I mean, I get the commentary (although I think it's unjustified because most of these things make sense within the story), but why is there a horde of animals stampeding through Emhyr's room?

Phase

He undoubtedly likes the game he just also likes making games look crap : p

ACuriousMind

I thought so, but I don't really get this kind of humor :P

Phase

Tbh I wouldn't be surprised if Emhyr kept a bear room to tear apart peasants

CooperCape

You know the feeling when...

you think 1x1=0

So you spend an hour wondering why you're wrong

Phase

20:35

1x1 is zero tho

CooperCape

:(

ACuriousMind

I have lost an entire grade in a course to thinking 3-4 = 7...

CooperCape

that's... not nice.

Phase

@ACuriousMind i hope those dots obfuscate a "...-8"

: P

ACuriousMind

@Phase lol, no

CooperCape

20:36

Casio fx83GT PLUS says it's 1

ACuriousMind

They obfuscate embarassed silence

CooperCape

huh

looks up obfuscate

gotcha

Phase

feelsbad :( i lost a few marks in a test going from $u'g(h(x)) + u \frac{dg}{dh} \frac{dh}{dx}$ to the next fucking line forgetting to write the u in the second term of the next line

Those errors are the most annoying imo

ACuriousMind

@CooperCape Using obfuscate obfuscated Phase's meaning to you? ;)

Phase

@ACuriousMind you've played ds3 right? Maybe this vid of his will be funnier to you :0

ACuriousMind

20:39

@Phase No, only 1 and 2

CooperCape

@ACuriousMind Mind=blown. Nah... It was just I didn't realise we were on the english stack exchange

Phase

damn

@CooperCape you're right

we aren't on the English SE so...

ACuriousMind

@CooperCape Oh, we've had some nice linguist discussions in the h bar :)

Phase

Color, flavor, humor

etc whoooooooooooo

CooperCape

@ACuriousMind Not my thing... just managed to scrape an A in my German GCSE and that's just about my linguistic capabilities.

ACuriousMind

@CooperCape Sehr gut! I approve.

@Phase Huh, you traitor Brit!

CooperCape

That's probably the wrong word order

Always got the wrong word order.

Phase

@Blue DOWN WITH THE QUEEN

CooperCape

And I kept on saying 'Der ist' for 'There is' because it sounds like it I guess?

Wait

Phase

20:42

This is gonna sound sarcastic but it's not: if I'm not gonna live in a country that doesn't speak English, is it worth my time to learn another language?

Is it fun?

CooperCape

Phase. Where. Are. Your. U's.

Disgusting.

I just noticed that

Ewwwww I've been around too many Americans ew ewew

get it off meeee

Anonymous

@Phase Yeah, if it's a programming language :P

ACuriousMind

@CooperCape It's the correct word order, but you said "I'm watching TV".

Phase

@CooperCape stop Clamoring

CooperCape

@ACuriousMind Yeah.. it was one of my 'hobbies'

@Phase coughs

20:44

@Phase Being multilingual is fun though

ACuriousMind

@Phase Yes. Learning a different language is a very good exercise in understanding other people, and comparing the similarities and differences between how languages tend to express common concepts is very interesting, imo

Phase

@CooperCape you're laboring under false presumptions that this is an English SE

You said yourself it isnt

CooperCape

We gotta keep some u's in there tho

Phase

@ACuriousMind I feel like this is gonna be a biased response but any particular language? : P

ACuriousMind

@Phase Nope, pick any you like

Phase

20:45

@CooperCape ok how about this as a compromise: Coulor instead of colour

hmmm

I've never really properly learnt a language

CooperCape

Deutsch ist sehr gut zu lernen!

Maybe?

Phase

I spent about half a year learning french for GCSE

and I hated it but maybe that's just french

CooperCape

Well, obviously I learnt English, and I also really enjoyed Latin and Ancient Greek although it's almost completely useless :)

CooperCape

@ACuriousMind Caesar est in hortuus

Classic

Phase

Caesar is in the garden?

CooperCape

Yeah

Phase

I learnt Latin too for a bit but I forgot I even learnt it

CooperCape

Caesar est in Cleopatra

Phase

20:48

and honestly I'm incredibly bitter about my Latin GCSE

Incredibly bitter

Sid

Guys a little help here. Why is that in a well with a finite height, the wavelengths that fit in are longer than that with an infinite height?

CooperCape

I only did Latin GCSE cause we got 2 for the price of 1. (Lit&lang)

Phase

Because they don't end at x = 0 or x = L

is my kind-of-an-explanation

:(

ACuriousMind

@CooperCape horto, not hortuus

CooperCape

Awww... :(

That's most of the Latin I remember

@Sid Because they're allowed to "penetrate" the walls, while they're not for the infinite well

(Basically what @Phase said)

Phase

Holy shit

I was useful?

Cows

20:50

Hi guys

CooperCape

@Phase You should do a physicse degree ;)

Mithrandir24601

@Phase obwohl dein Denglisch ist fantastic

Sid

Oh. Right, they don't have to end at x=0 and x=L. So, they can afford to be a bit longer. Got it.

Phase

CooperCape

20:51

Apologies, comrade.

Cows

I have a mathy question about QM , like pure abstracty math, that I have a puny handle on

anyone want to engage

?

Phase

ask first : P

Cows

please

Phase

dont ask about asking, just ask : P

Anonymous

@Sid i.e. can overcome the energy barrier :)

Cows

20:52

I wanted to define QM last night by myself

so I thought

1. you have some hilbert space H

essentially some set

and a morphism

to another set

another hilbert space

then one to a powerset

of that set

where the things we care about are found

Sid

Also, one of my friends questioned why is the probablity density taken to be the square of wave function and not any other exponent to even function. Any particular reason other than "that is how probability density of wave function is defined"?

Cows

in category theoretic speak

Phase

You can't really purely theoretically derive QM

afaik at least

Cows

say categories and morphisms,

ACuriousMind

@Cows You'll need to be a lot more precise for that to be right or wrong.

Phase

20:53

You need empirical results for the meantime

Cows

ok let me retry

ACuriousMind

@Phase He said define, not derive.

Cows

H arrow to right H then down arrow power set of H

Phase

O

shit

Cows

then we should have a functor

from P(H) to H

ACuriousMind

20:54

@Cows We do have MathJax here, please use it, see the room description in the top right corner for a link

Cows

ok, getteing mathjax now

ACuriousMind

@Sid No. It's an axiom.

Sid

@ACuriousMind axiom?

ACuriousMind

@Sid Postulate, assumption.

Sid

@ACuriousMind Oh, so, "it is assumed to be such"?

ACuriousMind

Born rule

The Born rule (also called the Born law, Born's rule, or Born's law) formulated by German physicist Max Born in 1926, is a law of quantum mechanics giving the probability that a measurement on a quantum system will yield a given result. In its simplest form it states that the probability density of finding the particle at a given point is proportional to the square of the magnitude of the particle's wavefunction at that point. The Born rule is one of the key principles of quantum mechanics. There have been many attempts to derive the Born rule from the other assumptions of quantum mechanics, see...
