the technical name is worldsheets
but worldsheets also applies for open strings

dammit, the original tweet is deleted
now I don't know which question sparked the backlash to get IPS booted
@Secret I like "tubes"
wowzah, found a meta post with the actual questions involved
those questions are so vanilla lol
holy jeez

somehow a question asking about how to tell someone they are autistic is "ableism"
danielunderwood
danielunderwood
This is a weird question, but have you ever just felt the saltiness while playing a competitive game? I've had these periods of like tense super-stress...or maybe I'm just weird
enumaris
enumaris
o.o I've gotten pissed off at losing
do you mean that?
I've also got stress from not wanting to lose

A: How do you tell a Facebook friend that they might be on the autism spectrum?

AstralbeeAutism is understood today in a way that it never was in the past, which is why so many kids are getting a diagnosis, but also why so many adults that may be on the autism spectrum were never diagnosed. You point out that there is a clear difference between thinking you are on the autism spectru...

the OP is autistic himself...uhhhhh
danielunderwood
danielunderwood
lol maybe I'm just weird. It's a bit different than just getting pissed...like a thing across multiple games
A facebook friend that he's never met and they have no mutual friends?
Actually I suppose that may be like talking to people on here
enumaris
enumaris
01:06
Lol
What's the difference?
For your video game thing I mean
danielunderwood
danielunderwood
uhhh like it always ends up with my back being super tense and it just gets worse the long I play
Maybe I sit differently when I start to get frustrated or something
Or maybe the other people insulting me are doing it to relieve that feeling

what does moduli stalilization, which often appears in the context of string theory, mean? Does it mean to remove the singularities of a moduli space?
John Rennie
John Rennie
10:20
@CaptainBohemian the moduli are the parameters that determine the geometry e.g. the size of the compact dimensions.
In principle the moduli are free parameters, and the trouble with this is you'd expect them to naturally shrink to zero or expand to infinity. So why don't they?
This is addressed by theories like KKLT that suggest a mechanism for fixing the values of the moduli, hence moduli stabilization. I don't know if KKLT is still considered the state of the art in string theory of whether it's since been superceded.
Captain Bohemian
Captain Bohemian
10:43
@JohnRennie how does KKLT fix the values of the moduli? introduce some extra fields?
John Rennie
John Rennie
@CaptainBohemian KKLT is so amazingly complicated that even Ed Witten found it baffling, and I have absolutely no idea how it works. It's to do with wrapping of strings round the compact dimensions.

@Nobodyrecognizeable Your answer is one that is commonly used to explain why light travels more slowly in a dielectric, but it's an oversimplification that is fine at the pop science level but not for physics students. I'd guess that's why it has attracted downvotes.

@JohnRennie @ACuriousMind Hi there :), I had a general question about solving Heisenberg EOM, I've heard people discussing "if you solve the backward Heisenberg eq, you can get rid of the time ordered exponentials...", and I'm trying to figure out what they meant. I guess this starts from the fact that we have a Hamiltonian operator where $H(t_i)$ and $H(t_j)$ don't commute for i and j different (and hence the time ordered exps). Do you have any guesses what they must have meant?
John Rennie
John Rennie
I wouldn't have downvoted it because it is a common description, but I guess the downvoters disagree with me.
@user929304 I've never studied matrix mechanics I'm afraid.

@Slereah it depends on what you mean by that

@Slereah If you're interested in the quantum-optics-hhg project, then you should mention explicitly that you've been in contact with me, that you've seen the project proposal for blending QO with HHG, and that that's one of the areas that you're interested in exploring (or something like that)
if there are other areas our group works on that you're also interested in, then obviously mention them
Slereah
Slereah
Well if it has non-perturbative QFT stuff that indeed could be nice
got a link to the group?.
Emilio Pisanty
Emilio Pisanty
be as specific as you can
@Slereah we don't do QFT much. This project doesn't really do QFT - only insofar as quantum optics does
you won't need anything that isn't in Gerry & Knight
at least to start with
Slereah

It's pretty hard to randomly find people you know browsing universities, really
I only found two that way
Henneaux and Di Francesco
But then again, not that many big theory people around here
It would really be nice if there was a centralized list of PhD topics really
Just finding it on each site is an adventure
Apparently Yvonne Choquet Bruhat's last PhD student was in 1975
Probably not a good idea to ask

Quick question: is there any widely-used symbol to relate two physical, measurable quantities in such a way that $v_1 \mathbb{R} v_2$ iff $\mathrm{sgn}\, \mathrm d v_1 = \mathrm{sgn}\, \mathrm d v_2$?
danielunderwood
danielunderwood
I also find it impressive that he asked a previous question that wasn't all caps
Slereah
Slereah
15:45
@LucasHenrique Same derivative sign you mean?
Lucas Henrique
Lucas Henrique
In other terms, $O(v_1) = O(v_2)$. My motivation is usual language: for example, Newton’s law of gravity; more distance, less force. But not a direct proportion.
@Slereah yes, pretty much. Stopping to think, the differentials here are nonsense.
Slereah
Slereah
Can't really think of a widespread symbol for that, no
Emilio Pisanty
Emilio Pisanty
@Slereah there are several
I've lost track of where they are
but they do exist
Semiclassical
Semiclassical
$\Delta v_1\propto \Delta v_2$, maybe
Slereah
Slereah
@EmilioPisanty Well yes, but that's kind of the point
Semiclassical
Semiclassical
15:51
or maybe just $\Delta v_1\sim \Delta v_2$
Slereah
Slereah
"several" is pretty much the opposite of centralized
And most universities don't even list them there
So I just have to go scrounge a hundred websites
or just send random emails to scientists
Lucas Henrique
Lucas Henrique
Isn’t that direct proportionality tho?
Slereah
Slereah
Yeah, you could have $x = -y$ and then it would still be $x \propto y$
Semiclassical
Semiclassical
oh, you're interested in the sign of the changes being the same

Even though it's the opposite of what you want

@Slereah Heh. By the way, did you consider applying to the US or Canada side also? Or is Europe better for you due to the locational advantage?
Slereah
Slereah
Europe is better indeed
Although if things don't pan out I guess I'll try broadening to the US and Canada, too
It is some kind of utility function that has the topic of the thesis, the proximity to here, the salary, how much time is left and whether or not I know people in that city are the parameters
Anonymous
US applications seem a bit easier in the sense that they have formal admission processes, rather than - "mail and wait for response"
Slereah

So as time goes on I'll probably look more into the applied QM thesis and US thesis
