But in the free case the operator is just gonna be a sum of operators multiplied with distributions anyway
 
>implying path integrals are well defined
 
@Slereah In the free case the fields are just made out of creation and annihilation operators, yes.
Some even prefer to define the annihilators and creators first through their actions on the Fock space and then define the quantum field out of them
 
@ACuriousMind Wald
He defines them abstractly using Hilbert space index notation and then shows quantum fields are just expansions of them
 
Huy
Is there a reason why Slereah never uses LaTeX?
 
he's a punk, that's why
 
Huy
9:03 PM
I understand.
 
Also I don't have mathjax on
Also IN MY DAYS WE DIDN'T HAVE LATEX ON CHATS
 
Huy
That's a single mouseclick.
And you've only been a member on SE for a year and a half.
 
wow Skyrim Audio overhaul nearly killed me
 
Huy
@0celo7: Did you also buy Skyrim most recently?
 
But the chat only a few weeks
 
9:05 PM
the audio for summoning Atronachs is fucking loud
@Huy on PC, yes
 
Huy
@Slereah: Are you kidding? I've been using LaTeX in chat for years.
 
Well I use mIRC
 
Huy
@0celo7: Do you like it or are you just experimenting with mods atm?
 
So not much latex there
 
@Huy No my mods are set
 
Huy
9:06 PM
@Slereah: That's really not our fault is it?
 
but god damn that was loud
 
Huy
@0celo7: STEP or some custom set? Which ENB?
 
>ENB
I have a potato
 
Well yes but is it so hard to read WORDS
"phi = 1" isn't horribly hard to read
 
Huy
@0celo7: Why? You seem to be able to stream, so your PC must be half-decent?
@Slereah: |a> hurts my eyes.
 
9:08 PM
@Huy it can't run Witcher 3 D:
it's a potato
 
Huy
@0celo7: Sorry about that.
@0celo7: We could exchange PCs, I stopped playing games that need decent specs a while ago. Well except for Cities Skylines.
 
I don't have a PC
 
Huy
lol
don't tell me you're playing on a laptop
 
I have an Apple laptop that I've tried beating into submission
 
Huy
That is the worst combination I can imagine for playing games.
Except maybe if you emulate an Android phone on your Macbook and play games there.
 
9:10 PM
What about if I use Γ = ☎-1ΨΨ̄
(☎ is the telephone operator)
 
The biggest problem is that my GPU is not supported by anyone
And it's underclocked to shit because there are no fans in this thing
 
Huy
@0celo7: Well, Apple laptops aren't exactly made for gaming...
 
@Huy I know. I want to see what would happen if I OC'd this thing.
It's an extremely good laptop.
 
Huy
@0celo7: I can give you the advice to not use it as a laptop anymore then.
 
The GPU is the bottleneck. It's not a gaming GPU and it's underclocked.
 
9:12 PM
∇5Rmagδσreg⊗ Υα̇β̇...∫d4p e[42] =LGreco+5+∂Λ̂+V̌+2256 αS(μ2),
 
@Slereah are you drunk
 
Huy
@0celo7: Still an extremely good laptop doesn't compare to a fairly good gaming PC.
 
I am just quoting bits from the Stuperspace paper
Because it has horrible equations :p
 
@Huy I know.
 
Huy
Good.
 
9:13 PM
@0celo7 I'm not sure that is something one would be able to type while drunk
 
Huy
@0celo7: I actually want to buy an Apple laptop next. So we could still trade!
 
I also have really weird problems with it. Random crashes, fps glitches.
@Huy I need this laptop for college. My old one was fuck slow.
 
Huy
@0celo7: But my GPU can run Witcher 3!
 
@Huy Good for you?
 
Huy
Thanks. I'm patting myself on my shoulder in this very moment.
 
9:16 PM
How much is a decent rig these days? Assume I don't even have a monitor, mouse or keyboard.
 
Huy
(I actually didn't check if my PC can run Witcher 3. Ridiculous what specs are needed o_o)
 
@0celo7 Can't tell in your weird overseas money :P
 
If you think that's bad, check the latest Assassin's creed. Min GPU is a 680.
@ACuriousMind lel the Euro is so shit they're almost equal
 
Huy
@0celo7: Depends on what kind of monitor, mouse and keyboard you want. My keyboard and mouse alone added more than $500.
 
@Huy What the fuck?
 
Huy
9:19 PM
Wow, that is ridiculous for AC. I have a 7950, it requires a 7970. Time to upgrade?
 
@0celo7 I think I paid ~1300€ for my setup two years ago, where about 1000 were for the rig, I think
 
@ACuriousMind ::looks at laptop:: I could have bought that twice.
 
Well, why didn't you? :D
 
Huy
@0celo7: I would say for $1000 you can get yourself a more or less decent gaming PC, without peripherals. If you want a good one, you should add 50-100% of the price.
 
@ACuriousMind Was not my money.
 
Huy
9:20 PM
@0celo7: And knowing how expensive Apple laptops are, you could have gotten yourself a really good gaming PC.
 
"You won't have time to play games in college."
@Huy It's a moot point because it was not my money to spend.
 
@0celo7 lol
 
Huy
@0celo7: I paid around 1500-2000 three years ago, and upgraded some parts.
 
And I still would have needed a decent laptop.
 
Huy
@0celo7: BTW, Eizo FS2333 and Corsair K70 RGB. I recently got the keyboard for free because my old K70 had a broken backlight behind some keys. They didn't ship the K70 anymore so I got a free upgrade to a K70 RGB.
 
9:22 PM
I'm using an Apple Wireless keyboard and some Dell mouse I found in my uncle's basement.
 
Huy
@0celo7: For anything you do in college a $1000 laptop is more than enough, maybe put in a few extra bucks for something better.
@0celo7: I used to think mechanical keyboards didn't make a huge difference. Boy was I wrong.
 
@Huy If I really wanted I could buy a very good gaming PC. But I don't want to blow my college spending money at once.
 
Huy
Sure, that's very reasonable.
 
It's not that bad, I missed out on a lot of games over the years. Now I'm playing the oldies like Oblivion, Morrowind and Bioshock for the first time.
I can run GTA 5 on decent settings.
But I've heard that game is unusually well optimized.
 
Huy
@0celo7: I wouldn't know, I bought it for my PS4 way before it was out on PC and hoped there would be some way to get the PC version for a discounted price if you already have some console version. I really don't want to pay almost full price for a game I've already played.
@0celo7: Bioshock is great, although I've only played Infinite (Steam sale). I'm not a fan of RPGs, so I never tried Oblivion and Morrowind :(
 
9:34 PM
"[42]
No, dummy, it's an exponent, not a footnote. "
heheh
 
@Huy Infinite was great.
 
Huy
Definitely.
 
I've played that one, haven't started on the rest of the series.
I got the Bioshock bundle for like $10
 
Huy
@0celo7: Do you enjoy open-world games in general?
 
Yes, but I also like "linear shooters" (@ACuriousMind's word).
 
Huy
9:38 PM
@0celo7: Ever tried the Arkham series?
 
no
not into Batman
 
Huy
@0celo7: Sleeping Dogs?
 
@Huy about an hour and a half into it
 
Huy
@0celo7: Like it? MP3?
 
I do like it but I need to get bored of modded Skyrim before I get into it more
Skyrim is just so damn good
 
9:40 PM
@0celo7 That's just a description of what they are - shooters, and linear - not a value judgement :P
 
Huy
@0celo7: I played Skyrim for maybe an hour before I got bored. Then I discovered mods, invested about 8 hours to install mods and ENBs, then rode a horse along a lake for about 3 hours and then stopped playing Skyrim.
 
@Huy I'm approaching 500 hours.
 
Huy
@0celo7: I really really enjoyed Sleeping Dogs. I was very hyped for GTA5 and decided to play Sleeping Dogs until release. I got a few days of gaming out of it, but enjoyed every minute of it.
If I have too much free time some day, I'll play the Definitive Edition.
 
that's what I have
 
Huy
@0celo7: I don't think I have over 150 hours on any of my Steam games. LoL though.
 
9:43 PM
it was a midweek sale and I randomly saw it
 
Huy
@0celo7: Yeah, I bought it too, because I am sure I will play it some day.
 
@ACuriousMind yeah right
 
Huy
Ok, off to bed. Night everyone.
 
cya
 
@0celo7 I enjoy some of them - like Bioshock:Infinite. I think the linear shooter I liked best was Bulletstorm, though, it's just so ridiculuously over the top
 
9:54 PM
@ACuriousMind You gonna VTC as engineering? physics.stackexchange.com/questions/197923/…
I mean the guy admits to being an engineer...bad move on this site
 
@0celo7 The whole fluff it uncessary, but I'm not sure what the actual question is - there is no "maximum temperature" for stuff, it will just melt at some point.
 
What is "it"
I suspect it is a penis
 
Door handle
 
why the scare quotes, then
it is suspiscious
what is he hiding
 
@Slereah "it" is suspicious, you mean
 
9:57 PM
A bunch of other weird formatting
and a weird question
I'm for keeping it though
with the usual caveats about safety information
 
WHO RUNS BARTER TOWN
 
@Slereah you're a child
 
WHOOO RUNS BARTER TOWN
I don't think a child would know who runs barter town
 
@Slereah why all the indices here physics.stackexchange.com/a/197808/59215
 
I have no idea what this is about
 
10:05 PM
It's kind of an 80's reference
Why not
 
@ACuriousMind I think @Slereah is high and drunk most of the time
 
@0celo7 Seems like a reasonable explanation and a reasonable choice on his part to me
 
@Slereah why not $g(\dot\gamma,\dot\gamma)$ and $\nabla\phi=\mathrm{d}\phi$?
 
You phillistines
 
10:07 PM
why on Earth would you put indices there
why on Earth do you use varphi
 
Because I'm a physicist dammit!
Not a filthy mathematician!
 
I'm not either
 
I'll write in Penrose notation if I want to!
 
even me, a lowly pre-engineer, know that indices are shit
@Slereah do it
I fucking dare you
 
You know, penrose notation sounds like a decent idea
Until you have to work with them
 
10:08 PM
do it!
paint and then upload it
 
Like, tensors of rank 2 are okay to do in Penrose notation
 
@0celo7 You've talked too much to me, I think :D
 
But when you have rank 4
It's kind of shit
 
@ACuriousMind yeah I used to have self-esteem
 
When I had to work with penrose notation, my whiteboard looked like a squid orgy
2
 
10:10 PM
@Slereah please write $\nabla\phi=\mathrm{d}\phi$ in penrose notation and post here
 
I'm not even sure how to write a scalar field in Penrose notation
 
Bianchi identity :D
 
I guess it would just be a square?
 
wait can you actually derive things in penrose notation
 
Well yes
 
10:12 PM
@Slereah Why do you keep posting that picture randomly? :D
 
I mean, it's just a notation
Because I love it
Like if you have a penrose diagram, you have rules to transform it
for instance
 
@ACuriousMind it's like indices but much much worse
 
I concur.
 
"Your last message is too far back; please use the transcript instead" sigh there I go again.
 
are there classes for this crap?
I just realized chrome fixed itself
 
10:18 PM
@0celo7 Abstract art, perhaps?
 
Not that I know
But there are articles and books
though I suspect that it might be just one or two dudes
 
@Danu I don't think you missed much, there aren't many starred messages after your last :P
 
Yeah I can't recall anything interesting happening.
 
You mowed the lawn.
 
@Slereah I'm going to edit that post to get rid of the indices.
 
10:21 PM
^squid orgy
Also do not
 
@ACuriousMind Wrong direction of the accent (just FYI)
 
@ACuriousMind that's not interesting
@Slereah will too
 
@Danu lol, I just randomly typed one because I can never remember
 
Look at this horror
 
...and they really think that's easier to follow than just...writing it down?
 
10:24 PM
@ACuriousMind You can hear it.
It's not tou-chehh, but tou-cheee
 
@Danu I don't know a single thing about French
 
@Danu TIL those things actually make different sounds
 
Occult symbolsd
 
lol what
 
10:26 PM
I should have done my calc project on this
 
It's even more awful than penrose notation
Because it's Penrose notation applied to group theory
Pretty sure if you write that down the Blair Witch will come
 
@0celo7 You Americans :P
 
@Slereah I think even she is horrified by this
 
that's like physics equivalent of Nazi zombies
 
@Slereah Physicists + group theory = HELL ON EARTH
 
10:28 PM
group theory and penrose notation are messy, and put together they are satanic
 
then again
Spin nets are satanic as well
 
lol
 
I think next time there is a tensor question
I will try to answer it in penrose notation
 
do it
 
I really wanna try that chalk now, @ChrisWhite. Any chance you could mail me some (not even kidding)?
Don't really wanna pay 50 to get a box of it from here
 
10:31 PM
@ACuriousMind oh you rascal boards.4chan.org/sci/thread/7444818
 
Also, that's almost a dollar per piece of chalk...
 
@0celo7 Huh?
 
@ACuriousMind forget it then
 
I'm not even sure how to read 4chan threads, I think :D
 
what? it's a very intuitive layout
unlike reddit
 
10:43 PM
for reddit you just need RES
 
The fact that Penrose notation exists
just kills my faith in humanity
 
the fact that your FACE exists
 
claps slowly
 
haha whaat?
 
10:54 PM
Yeah, it was all over by the time I got there :(
Shhhh @0celo7 or they'll gang up on you pal.
 
I just randomly got an SNES emu, works perfectly
holy crap
is there a Gamecube emulator?
 
the cubemu
 
well now I can play SNES in class
this is horrible!
I crashed the emulator
it can't into 1800p
 
11:15 PM
Huh. The debris they found is from the missing malaysian plane.
 
@NeuroFuzzy Hmm?
 
I stick up for my pals
This version is better
 
Fun fact: When somebody posts something in the Teachers' Lounge (the network-wide mod chat room) containing a link to another room, and flags simultaneously pop up on the corners of mods screen, there is roughly a 100% chance that 6+ mods will enter that room within 30 seconds. It's simple curiosity.
Actually, that's not a fact, just a stat I made up off the top of my head. But it's still pretty accurate.

Wow, thanks for the info pal.
 
is there anyone that isn't your pal?
 
11:27 PM
Those that prove themselves unworthy
 
@FenderLesPaul John Duffield, I'd guess.
 
The word pal has lost all meaning :P
 
dun dun duuun
Ah yes John Duffield
 
cubemu...
 
still have no idea why he's allowed to post the stuff that he does
 
11:27 PM
will check out
 
@Danu apparently the french and the malaysians are saying different things so it might not be confirmed. en.m.wikipedia.org/wiki/Malaysia_Airlines_Flight_370
 
@0celo7 dude I made that up just in case you do search that
 
@FenderLesPaul I was just about to ask
 
I don't wanna be responsible for whatever possible traumatic images that search might result in
 
11:29 PM
...what images could "cubemu" possibly result in? ::googles "cubemu"::
 
I really need PS2 emulation to be a thing as well.
 
I get...cubes, mostly :D
 
Also PSX.
I need to play MGS again...
@ACuriousMind Do you like my new avatar? I see it has finally refreshed.
 
looks like an obese cat
 
he's fucking fluffy, OK
 
11:32 PM
@0celo7 You already posted it before, it's very cute and...peaceful
 
is fluffy his ho?
 
@FenderLesPaul no the dog is his ho
the dog is also fluffy
so yeah fluffy is his ho
 
interesting...
 
@ACuriousMind peaceful because he can sleep and you can't?
 
@0celo7 Yes, that's it. I'm envious of his ability to sleep
 
11:34 PM
@ACuriousMind he can sleep anywhere you know
 
I know, that's what cats do
 
under my bed, on my bed, next to my bed, across from by bed
 
I do that too
 
right now he's staring at me...little perv
 
@FenderLesPaul You sleep under 0celo7's bed?
 
11:35 PM
I think he has lost weight @ACuriousMind
 
@ACuriousMind yes
 
in Mathematics, 46 secs ago, by Kevin Driscoll
physics chat isnt as active as this chat
 
alrighty then
 
is math chat really more active than we are?
we get pretty active around this hour
 
How should I know, I don't visit math chat
@0celo7 Not enough mice?
 
11:36 PM
programming buttons for an emulator -- this is hard
I need to connect a controller to my laptop
this is getting really ghetto
 
I asked my mom for a cat once
 
@ACuriousMind he's not an outside cat
 
she said I was too retarded for a pet
:(
 
@0celo7 nope!
 
@0celo7 Mice don't necessarily live outside :P
 
11:38 PM
@ACuriousMind I figured you were implying this.
how on Earth does Wii emulation work on a PC
 
Why the hell are you looking at emulators?
 
He's going off to college and feels old
so he wants to relive his childhood games
I support you @0celo7
 
@ACuriousMind why the hell are you not
@FenderLesPaul this, I want to play the old Zeldas
 
@0celo7 Because I need to level my templar
 
@ACuriousMind fucking PoE
 
11:41 PM
@ACuriousMind what game?
@0celo7 Dude Windwaker
is my jam
 
@FenderLesPaul exactly
 
@FenderLesPaul Path of Exile (you might know it as "that Diablo 2 clone" :D)
 
Welcome @KevinDriscoll
 
I doubt I'll get an answer to this, but does anybody know what the rate of depletion is for lithium in supernovae, either via decay into two helium nuclei or via traditional lithium burning via the p-p chain? It's based on this question.
 
@FenderLesPaul I also want to play Okami but I'm doubtful Wii emulation works well since that game uses the Wiimote a lot.
oh my lord I need to play Pikmin
I need to play it
 
11:45 PM
is Okami the really pretty game with the fox?
 
yes
Also I need to play Pokemon XD and Colosseum.
I have those games but I can't find my mem card anymore :(
 
@NeuroFuzzy Cool
@FenderLesPaul wolf!
 
wolf $\cong$ fox
 
@0celo7 In what category?
 
@Danu right Wolf
I miss Pokemon!
 
11:51 PM
@ACuriousMind animalia
@FenderLesPaul I got $\Omega\mathrm{R}$ but haven't played in ages
$\mathrm{AS}$ was very good
@ACuriousMind dumb question: what does category (what is a category) have to do with this
I'm just saying there's an isomorphism between fox and wolf.
 
@0celo7 Right, but you have to say what an isomorphism is, i.e. which structure the morphisms preserve. That's part of the defining data for a category
 
@ACuriousMind uh, tail, legs, teeth
 
An isomorphism of whats :D
 
well this was not rigorously proved
is there like an approximate isomorphism symbol?
 
@0celo7 So, a morphism between two elements of animalia is given by a map between the tails, lets and teeth of the animals?
 
11:56 PM
@ACuriousMind I guess not all animalia have those features!
@ACuriousMind carnivora?
 
@0celo7 Well, there is a map from empty sets to themselves, so no problem. This would mean that all animals without tails, legs and teeth are isomorphic, though
 
@ACuriousMind you sound skeptical
@ACuriousMind jesus
Stop being such a damn pedant.
 
Additionally, they would be the initial objects
