@ACuriousMind Sorry man, it's just not for me

Bologna is a shitty educational system

IMHO

Mh, Bologna is a funny system where universities, in particular between countries, are still so different as to not be using a common system at all :P

0celo7

Bologna?

ACuriousMind

At least in my impression

0celo7

The sandwich meat?

ACuriousMind

The stories others tell about it never seem to match my personal experience here at all.

@0celo7 An european treaty to """"unify"""" curriculums for EU universities

ACuriousMind

@0celo7 The European process

0celo7

Your curriculum is so strange I can't believe anyone agrees that it's good.

Bernardo Meurer

Here it's shit

@ACuriousMind Have you seen my insane Analysis II syllabus?

@0celo7 It's insane, right?

ACuriousMind

@BernardoMeurer I don't think so

@0celo7 You have to keep in mind that my particular curriculum is a bit weird because I chose it to be :P

Bernardo Meurer

@ACuriousMind Since you understand my weird ass language better than expected, here math.tecnico.ulisboa.pt/~jpnunes/CII/programabibliog2012.pdf

If you don't get something tell me

This is a single semester

vzn

1:04 AM

@0celo7 seems strange to hear you talk about "duty of children towards parents"... you think they should go along with parents choice? & seems hard to picture you doing that o_O

ACuriousMind

@BernardoMeurer Ooof. If I'm getting it right that looks like my Ana II and Ana III courses smashed into one

Bernardo Meurer

@ACuriousMind Exactly

0celo7

@ACuriousMind I'm talking about his, not yours

He's an engineer who is forced to take analysis and quantum mechanics

like what the hell

Bernardo Meurer

And I believe you all remember the crazy Chem course

it's just a mess

Really, and it's making me miserable because I feel stupid

0celo7

I just don't understand how one is supposed to do that much analysis in one semester

ACuriousMind

1:06 AM

Here the computer science people have to take Ana I but not II or III if they don't want to

0celo7

I could sit here and go through all of the proofs and not be done for a month

Insanity

Bernardo Meurer

@ACuriousMind I take Analysis I, II+III, Complex Analysis

I have to take those

otherwise I don't graduate

ACuriousMind

That does sound rather like overkill to me

And that's what I meant when I said other people's "Bologna" stories don't sound like mine at all

0celo7

@vzn of course they should

vzn

@0celo7 huh, is nuclear engineering/ physics/ math your parents choice?

0celo7

1:08 AM

if parents have strong views then so be it, children are free to run away and not take parental assistance

@vzn no

vzn

@0celo7 so they express no preference?

0celo7

my mother has 4 arts degrees, by father 2 stem degrees

they have no preference

vzn

what STEM?

0celo7

only that I don't starve to death after my 9 years or whatever in school

bolbteppa

Math is an arts degree

0celo7

1:10 AM

math is not an art degree

bolbteppa

The world would beg to differ

0celo7

it's a rather useless STEM degree if anything

heather

oh, so there's the acronym "STEM" and then there's a new acronym "STEAM" - science, tech, engineering, art, mathematics

Bernardo Meurer

Isn't the M in STEM for Maths?

vzn

correct, some schools math is a BA afaik... surprising factoid sometimes

0celo7

1:10 AM

@heather yeah, that's stupid

Bernardo Meurer

@ACuriousMind Yeah, I hate it, I really hate it

0celo7

what is not in STEAM?

besides mass effect

heather

i found that kind of strange; the whole point of the acronym STEM to isolate the more "rigorous" subjects

@0celo7 i don't know =)

Bernardo Meurer

@heather That's butthurt arts people wanting to eat away our budget because they don't get any since they don't make GDP

0celo7

@ACuriousMind I figured out why I like MGSV so much. The currency is GMP

It's like GDP but for guns and stuff

ACuriousMind

1:11 AM

@0celo7 Are the humanities considered "arts" in English?

vzn

lol theres probably a lot of STEM that doesnt push the GDP much either :|

Bernardo Meurer

IDLES - STENDHAL SYNDROME

Talking about arts

0celo7

@ACuriousMind they are

liberal arts includes humanities IIRC

Bernardo Meurer

@0celo7 Really? I wouldn't say so

0celo7

you're not a native speaker

ACuriousMind

1:12 AM

I tend to have difficulties with subject classifications because the German Wissenschaft does not seem to really correspond to what the English world seems to mean by science

0celo7

@vzn aerospace

Bernardo Meurer

Fair, but still

vzn

@0celo7 aerospace + ? or 2 (masters?) in aerospace?

0celo7

@ACuriousMind the SJWs hijacked our science with "social science" and stuff

bolbteppa

Specialist degree

The specialist degree is an academic degree conferred by a college or university successfully completed five years of study. == The Specialist Degree in the Commonwealth of Independent States == The Specialist degree (Russian: специалист) in the former Soviet Union was the only first degree conferred in that country. The degree is traditionally believed to have originated in the engineering education of the Russian Empire. It currently is being phased out by the bakalavr's (Baccalaureate) and magistr's (Magister or Master's) degrees. In the early 1990s the bakalavr and magistr were introduced in...

ACuriousMind

1:21 AM

@0celo7 My point is exactly that English speakers seem to often apply "science" to mean "natural science".

While, except in certain contexts, I don't find that Wissenschaft is often taken in that narrow meaning

DanielSank

@0celo7 That is a fantastically terrible attitude that ruins people's lives.

@SirCumference listen to me, please. Do not go into a profession, or anything big in life, without a passion for it.

This is a fact known by mankind for time long forgotten: if you try to do something with a large commitment because you're supposed to instead of because you want to, you will not be happy about it and will likely inflict pain on other people as a side effect.

4

Obviously there are cases where it's good to follow through on e.g. a promise even though you don't want to, but that works best when the promise itself were made willingly, etc.

0celo7

@DanielSank Believe it or not, I don't really care if it ruins lives or not

DanielSank

@0celo7 Right now I care a lot less about what you think than I do about @SirCumference making positive life choices.

0celo7

That's fine

And I'm glad an adult is talking to him

But if you don't care, why did you comment on it?

Sir Cumference

@DanielSank Thanks a lot :)

I'll keep that in mind

DanielSank

1:33 AM

@0celo7 Because I care what information @SirCumference gets, and I think you're giving him very, very bad advice.

I don't care much what you actually think, but I care how you influence this other person who is clearly dealing with an important decision.

0celo7

I told him not to take my advice for pete's sake

ACuriousMind

...why are you giving advice that should not be taken? :P

bolbteppa

@0celo7 are you doing engineering for the same reasons?

ACuriousMind

That's like giving recipes for food that tastes terrible.

0celo7

@bolbteppa no

@ACuriousMind ¯_(ツ)_/¯

vzn

1:35 AM

"dont read this"

DanielSank

^ I failed

ACuriousMind

This space intentionally left blank.

0celo7

@DanielSank I've come to the conclusion that a lot of things I think should be would make the world much worse

Bernardo Meurer

@0celo7 That might be a meta statement

0celo7

But that's not why I think they should be, so there is no contradiction

vzn

1:36 AM

@DanielSank ps thx so much for trashing my msgs on physics

DanielSank

@vzn oh, you're welcome.

any time.

Are you going to send a sad face now?

Bernardo Meurer

@DanielSank Yes

0celo7

@DanielSank it's from 4chin

or wow

Bernardo Meurer

@0celo7 We love each other

DanielSank

@0celo7 It indicates love.

Bernardo Meurer

Such bullshit that first one

AoC is just a meanie

I wish old messages would retain old avatars

0celo7

@BernardoMeurer that's fine

Ramanujan

1:45 AM

@ACuriousMind no,it's only 2 star. (゜o゜)

OBE

@0celo7 lol you told him your gf's contact info?

0celo7

he got it from my sister

Bernardo Meurer

^

OBE

that's so weird lmao

0celo7

apparently they talk

it IS weird

Bernardo Meurer

1:47 AM

I help her with C++, that's it

I only actually talk to his sisters

0celo7

@BernardoMeurer she has to learn Python too

OBE

hey bernardo I have a compsci question

do you know much about web apps?

Bernardo Meurer

@OBE Shoot

Nope

not much

I don't like the web

OBE

oh :'(

Bernardo Meurer

But shoot

ACuriousMind

1:48 AM

@0celo7 Worried you might end up related to Bernardo? :P

OBE

do you know much about haskell?

Bernardo Meurer

Not much, but something

0celo7

@ACuriousMind ...what?

Bernardo Meurer

Just ask dood

OBE

dunno my friend is making a website in haskell and idk if that's okay. since i'm helping.

0celo7

1:49 AM

@ACuriousMind I refrain from engaging in this conversation. He will screenshot and make my sisters hate me.

OBE

i have to learn it first

ACuriousMind

lol

I'll just quietly chuckle, then.

OBE

@ACuriousMind you didn't answer my question

from before

did it make sense?

ACuriousMind

@OBE Which one?

Bernardo Meurer

@OBE I would **not** pick Haskell to:
1. Make a website
2. Be a first coding experience

OBE

1:50 AM

someone told me compact support of fields is required for your fock space to be separable.

@ACuriousMind

proof of that?

or hand wavey whatever

0celo7

does that even give you a Hilbert space

I don't actually know what the Hilbert space in QFT is supposed to be

@OBE the proof is likely horrible

OBE

I want a hand wavey argument

0celo7

proving separability of a function space is always pretty bad

OBE

I don't know enough to understand the proof I just want to know why it makes sense physically

0celo7

I'm interested in a mathy answer @ACuriousMind

what exactly is the Hilbert space in question?

ACuriousMind

1:54 AM

@OBE Not sure what to say about that without knowing what you mean by "Fock space", exactly.

OBE

the standard definition? or for hilbert spaces too

the noob definition you probably assume I am referring to

0celo7

what is a noob definition?

OBE

direct sum of hilbert spaces?

but ignore fock space why would it make sense for hilbert space

ACuriousMind

Well, a Fock space, in general, is just one built from the tensor products of a single-particle space.

So the question is not in the Fock space construction but how you think you're getting the single-particle space from your field

0celo7

^ that's my question

ACuriousMind

2:00 AM

There's also an issue that the naive Fock construction is always inseparable (as an infinite product of Hilbert spaces). I know there's a fix for this due to Segal but I don't really know much about it

dmckee

@TheDarkSide Nicely put. I've amended my answer to cover the current situation in a little more detail, but you pretty much nailed it.

ACuriousMind

@yuggib would be the guy to talk to about that, I think

dmckee

There is a point where politeness dictates taking a side-discussion onto the veranda or such-like.

0celo7

@ACuriousMind A countably infinite product is always inseparable?

ACuriousMind

@0celo7 The infinite tensor product, my apologies

dmckee

2:02 AM

And while the JEE will be of interest to—WAG—on order of 5% of potential Physics users at some point in their life, I suspect that it is of current interest to a rather smaller fraction at any given time.

0celo7

@dmckee why do mods always link the main site

@ACuriousMind Hmm, why is that?

I don't think I'd know how to go about constructing an infinite tensor product rigorously. Maybe a direct limit or something

dmckee

@0celo7 Can't speak for anyone else, but I do it to be painfully explicit that in this case the string "Physics" means the site and not the subject.

0celo7

I haven't given Fock spaces much thought

ACuriousMind

@0celo7 Ugh, it's a badly behaved construction to begin with that I don't feel like revising at this time

0celo7

@ACuriousMind what do you feel like then

OBE

2:06 AM

probably sleep

ACuriousMind

Going to bed soon :P

0celo7

he's a vampire, don't be silly

@ACuriousMind I didn't catch what you said earlier, does $\le$ mean a subgroup?

ACuriousMind

7 hours ago, by ACuriousMind

@0celo7 Some use it for "is a subgroup of" (and a triangle instead of the < for "is a normal subgroup of")

0celo7

@ACuriousMind Wait what

I thought the triangle was the usual notation for normal subgroup

ACuriousMind

It's common, yes

0celo7

2:10 AM

@ACuriousMind Suppose $n$ is a natural number, and $k$ is the unique nat number s.t. $2^k\le n<2^{k+1}$. How can I show that $n/2^k$ can get arbitrarily close to $2$ for large $n$

ACuriousMind

Unless that's a trick question it's pretty easy

What's the largest $n$ can get for fixed $k$?

0celo7

$2^{k+1}-1$

ACuriousMind

Yeah, now divide that by $2^k$ and stare at it ;)

0celo7

I knew that already

i was hoping for something better

oh well

ACuriousMind
