@JohnRennie you got me there

but our +50 years old landlord came with us

@JohnRennie We are students our entire lives. Though I guess you could say, we are as children as well

@Jim I have made it my life's work to preserve a childlike approach to life :-)

@JohnRennie so when things don't go your way, you take your ball and go home?

@Jim Immaturity is a sadly underappreciated quality :-)

@JohnRennie Nuh uh!

If you disagree I can only say YAH BOO SUCKS TO YOU!

:: John crosses his fingers that doesn't get flagged ::

I am comfortable with both cophenhagan and Bohm

@MAFIA36790 Sir Cumference has been suspended twice for saying fduck. I think the flag reviewers are sometimes excessively enthusiastic.

@Secret have you asked them if they're comfortable with you?

well they cannot because they have died

@Secret In one of the MWI universes the Copenhagen interpretation is correct.

@MAFIA36790 that's a bit prejudiced. Why do you fear commies?

The key is $\psi$-ontic, and in a to be arrived paper from professors in my uni, they said they have proved the wavefunction is real

@MAFIA36790 don't be silly. Commies is one of those catch all terms that doesn't describe individual human beings.

There will be people living in, e.g. China or Russia, who are as warm and loving human beings as you could hope for.

And there are people living in the (capitalist) UK who are total shirtheads.

@MAFIA36790 Commies simply have a different philosophy from yours. One which they don't try to imposed on your life. Hating them is a product of fearing them. If you were truly unafraid of them, you'd see no issue with their existence and no reason to hate them simply for having a different philosophy. Fearing them triggers the fight or flight response about them. There is no way to run from their existence, so the only way to fight it is to hate them and act biased against them.

Hating people for simply not living the way you do (especially when they don't directly impact your life in any way) is a product of fear. Denying that means you let the fear control you. This indicates hatred as a form of cowardice

@Jim while I agree with the sentiment this is another example of using the word commies as if it meant anything useful - which it doesn't. The term is typically just used to mean people I hate.

@JohnRennie says the person who was just giving examples of people in communist countries

link?

Hmm, either I'm too stupid to follow the arXiv subscription instructions, or the arXiv has a problem with non-ASCII characters in the mail :/

@ACuriousMind can't it be both?

@Jim Well, that's a possibility too

Either way, I don't get the "regular daily listings" promised! ::shakes fist::

Yeah, I recently started receiving twice daily listing from them. This is more than I signed up for. I'm not sure I can handle two email blasts a day from arxiv

currently tried to focus on reading Iwasana decomposition but whenever the thought that there is a more than 10 pages of finite groups need to be read after that, I felt demotivated

Ahaaaa

Yes, it was the non-ASCII characters

@Jim just forward the extra one to @ACuriousMind

Heh

Not sure I want astro-ph or whatever Jim's subscribed to, though :P

gr-qc

everyone wants what I subscribe to. Anyone who doesn't like what I like is wrong

@ACuriousMind You should file a bug report. There's no excuse for choking on non-ASCII characters in this century.

Well, this decade, at least.

arXiv is old enough that the first version was probably some hacked-together 7-bit email script.

@rob Yeah. The subscription page doesn't say anything about it either, it's as if they didn't even think of the possibility that people might have non-ASCII in their names

@ACuriousMind Falsehood #9

@rob nice list. I have a student with no given name. Just a surname. Had to enter them into the system with a period under "first name"

She and her sister have no first name. Their brother has a first name, but their parents didn't give them first names

morning

@Jim I have a friend, Nur, with only a single name. He shows up in databases as "Mr. Nur" or "Nur Nur" or even in one semi-official place as "Nfn Nur", which I guess was some idiot data entry clerk's way of representing "no first name"

@Secret The section on this in Jost's geom anal book was good

@rob Not going to lie, I really like the name "Nur" and I can't figure out why

@0celo7 perhaps using the full word "analysis" would have been a good idea

@Jim Maybe

this one?

But in my high school, the analytic geometry class was abbreviated "anal geom" on the syllabi

not well thought out, that one

@Secret the newer edition would be better

Also "Nur" is the first of about five syllables, but that's how he encourages US colleagues to address him.

I own the 6th, I think

lemme check

yeah

great book

@rob Sounds like a fantasy book. "The Secrets of Nur"

the knights of Nur

^ love it

@Jim This particular Nur is basically the most non-fantasy-oriented person on Earth :-)

testing $\prod_{i\in A}$

The Facts of Nur

@Secret use $\prod$, not times

fixed

Induced superconductivity at interfaces

But in a tender scene in his story, a clueless seductress whispers, "Tell me about you, Nfn"

No fucking name?

hello

Oh, first name

@rob honestly anything is better than Gerard 't' Hooft'

@heather why are the boys crazy in your grade?

@Jim nur means "only, just" in German, so that just sounds weird to me

@0celo7 Is there a final apostrophe as well? I haven't noticed that before.

@0celo7, have you met 12-14 year old boys?

@rob The correct way is Gerardus 't Hooft.

I think 0celo7 was just throwing apostrophes everywhere to be sure :D

@heather Worse, he's been one once :P

@ACuriousMind, yeah =P

but honestly, I think it is just teenager hormones specific only to boys =P

@ACuriousMind Does the "'t" in Dutch play the role of a "von" or a "de" in other languages? Or am I revealing my ignorance?

@rob I think so, but I'm not sure what it exactly means, since the analogue to the German "von" or the English "of/o'" would be "van" in Dutch

It means head

Or is that hooft

@heather I haven't met one that wasn't well behaved and courteous.

Always makes me wonder why people complain about middle school.

According to Wiki, the 't means "the" (abbreviated "het") and so he's named "Gerard the head"

More like Gerard doesn't know string theory the head

@ACuriousMind I was well behaved and courteous.

So what is so bad about teenagers?

Maybe it's an American thing.

I had to memorize bible verses when I screwed up, so I didn't.

@Kaumudi Don't take life too seriously. You'll never get out of it alive anyway!

@JohnRennie Not with that attitude, yeah

(To make one of @Jim's favourite replies :P)

Caption: This is what a group looks like to me based on my feelings alone:

A many layered thing with a lot of a lot of orbits

Partial rationale: quotient groups and subgroups are important tools in understanding groups, so are normal subgroups, conjugates etc.

No women, no relationships, no death

@MAFIA36790 what the hell can we talk about?

no physics, good

so in a sense, a group does look like an abstract onion with a dynamic surface...

wtf there is not enough squares in that grid

@Kaumudi what?

@Kaumudi if you're determined to take me seriously (probably a mistake) I'd say some thing matter, but the cardinality of that set is smaller than teenagers believe.

Anyway, I have to go out and buy lunch, and that really matters :-)

@Kaumudi So what does that put in perspective? Some people enjoy their weeks filled with silliness, others want them to be filled with adrenaline and excitement, and yet others want them to be dedicated to a higher purpose, some people want all three, and some neither.

Maybe their finite amount makes each week "precious", but what "precious" means is entirely subjective

Therefore I argue that group theory is kinda visual

@ACuriousMind, it doesn't matter, as long as each individual is maximizing their own measure of "preciousness"

@Kaumudi No, but you kinda sounded as if you were suggesting that being silly is not the right use of preciousness

@Kaumudi, yes the graph makes me seriously want to have more fun

and sillyness

@Kaumudi Eh, then I have no idea what this conversation is about. Ignore me :)

@Kaumudi, and ACuriousMind's argument is that having "so many days" can be used to argue for either (a) taking life more seriously and also for (b) not taking life seriously

I think we have a fundamental miscommunication about what "taking life seriously" means but I'm not sure it will benefit anyone if we hash this out...

@Kaumudi, should we colour in one of those blocks in the graph and allocate it to hashing out this question lol

i think not

na mate don't apologize

difference offers everyone a refreshing viewpoint

@ACuriousMind : The planet or Bruno? :)

@ACuriousMind yikes

@Qmechanic Haha, actually I hadn't seen that one yet

@ACuriousMind I'm glad someone is finally getting the concept

Jesus, that Indian uses question and doubt in the same though

What's this obsession with sanitizing the chat lately

What the hell?

@MAFIA36790 Disagree.

More like unnecessary use of it.

@0celo7 It's not nice to talk about people in a place where they can't reply.

@ACuriousMind Yes, this. Furthermore, discussion about who can or can't or is or isn't participating in the discussion is distracting and boring.

Stop removing my messages.

No, let's talk about something else instead.

Here's a physical model of a quadrupole magnet focusing system:

nerdist.com/…

Can we talk about music? I'm going to see the Hawklords in four hours!!

@rob Does that rotation actually turn the unstable equilibrium into a stable one?

@ACuriousMind At the right frequency, yes.

And I shall drink beer, and the atmosphere may get a bit, erm, fragrant with smoke :-)

@rob Is that right frequency a threshhold, or a "sweet spot" you must?

@ACuriousMind Sweet spot. The video shows the ball getting ejected for too-low and too-high frequencies.

Real accelerators have to use feedback systems to stay on-resonance.

Herbs

That's what happens when you go to a gig with several hundred other aging hippies!

@obe Yes, if "it" == "\LaTeX"

@JohnRennie How many years have you been a fan now?

:: counts on fingers :: 41!

@JohnRennie Wow, you have a lot of fingers

not 41 factorial

@JohnRennie Still a lot of fingers

@obe Well, I find that writing down stuff helps me learn it. Whether you do that by hand or by LateX is probably irrelevant, though the LaTeX tends to distract me because I go off for hours playing with the formatting :P

@JohnRennie You're impressively loyal, then ;)

@ACuriousMind or stupidly stubborn :-)

There's a difference?

:-)

So tomorrow morning I'll be tired, hung over and deaf. An ideal state to go through the review queues.

You...read up on it and ask someone who was there to help you with it?

@JohnRennie I'm completely undecided whether the second sentence is serious or not

@obe You shouldn't expect people to offer help. You need to ask for it, but that shouldn't be your only interaction with the other students. I know that just talking about the lectures with others has helped me understand a lot much better.

Are there notes for the class you could copy?

@obe Eh, I found it more annoying than hard, but our lecturer was a theorist who didn't particularly like scattering calculations himself, so I suspect we did less of them than is usual.

@obe Stop changing your pic!

Just pick a name and pic and stop confusing everyone

@SirCumference I'm not sure anyone but you is confused about this :P

@ACuriousMind It bugs me when y'all change your pictures

@SirCumference: have you made your peace with degenerate gases?

@JohnRennie Almost entirely

I like changing my picture. It's much easier than operations in real life and has the same effect on people when they see me afterwards

All that's left is to start analyzing the Schrödinger equation

See, the physics chat is a good place to learn how to deal with degenerates :-)

Are any of the properties of degenerate gases related to the Heisenberg uncertainty principle?

The HUP is a result of the way systems are described in quantum mechnics

You hear people say such and such happens because of the HUP but that isn't a good way to view what is going on.

The HUP isn't the reason the systems behave as they do. It's a consequence of the way they behave.

@JohnRennie This. So much this.

I have to walk into town to go the Hawklords gig, and it's started raining. Do I wear my sensible coat or my aging but much loved German police coat with POLIZEI written on it in reflective tape?

@vzn It won't be a good demonstration of QM unless they can demonstrate entanglement along with Bell violations

@JohnRennie How did you obtain a German police coat?

And is it legal for you to wear it in the UK? In Germany you'll get into trouble if you wear something that could reasonably be mistaken for a law enforcement uniform

Can't remember. I've owned it for decades. It came froma surplus shop I think, though why they had stock of ex German traffic cop coats escapes me.

@obe Nihilist

@ACuriousMind I've never been picked up on it. I think polizei is sufficiently different not to be confused for police in the UK. And it's olive green not blue, like UK police uniforms.

@obe That's for philosphy SE

But really, just spend time enjoying life

And helping others enjoy it

There's nothing inherently wrong with that ideology

I am only a nihilistic when I am emotionally frustrated. When I am peaceful, I do nothing

@obe What would be the point of doing anything if we were immortal?

Even if we'll all die, there's nothing wrong with enjoying life as much as you can

Thoughts on Immortality ...

By another aging hippie group.

That's not to say you should do something stupid, but don't think death makes life meaningless

You've got an opportunity to see a whole Universe now
