It would blow their little flat minds.

@ChrisWhite 3 instead of 2 possible polarizations for light, 2 instead of 1 independent spin number, I think.

Also, no chiraility for fermions because 4+1 dimensions don't have Weyl spinors.

@ACuriousMind lol

@ChrisWhite silly man, the universe is 11D

Anybody know about natural units? the concept of natural units is confusing me..

what's confusing about them

@0celo7 like when you are using an equation, u set $\hbar , c, k = 1$ but when doing conversions , you use the SI equivalents?

I'm confused by your question

please rephrase

@0celo7 so when you are using an equation, u set $\hbar , c, k = 1$.. correct?

@0celo7 but when doing conversions , you use the SI equivalents?

yes

conversions?

@0celo7 like for two different units...

are you trying to go from natural to SI?

@0celo7 no, all three, SI to natural, natural to natural, and natural to SI..

what is natural to natural

Why would you need to go "natural to natural"? That sounds like the definition of an identity transformation.

@0celo7 converting for example cm^-1 to s^-1 in natural units...

cm is not a thing in natural units...nor is s

@0celo7 well, I guess it is cm^-1 hc/k

Well, you do have one unit left in natural units - which one commonly chooses to be eV, but you can choose any one unit to measure everything it.

@DanielSank did you get time to answer my collapse operator question?

@TanMath Unfortunately, no.

@ACuriousMind ah.. so I guess that one unit in this case is cm^-1..

@0celo7 so for this, I use SI equivalents?

@TanMath Basically you take the square root of the transition rate and put it in front of the operator. I would like to write up a derivation of this fact, but it may be a while or never :-)

@DanielSank in front of what operator?

@TanMath You don't by any chance have "Exploring the Quantum" by S. Haroche, do you?

u mean like $\sqrt \gamma * C$?

@DanielSank no, why?

@TanMath What's $C$?

@DanielSank idk...

@TanMath That book explains this all really clearly.

@TanMath one second...

@DanielSank oh.. I'll look into it...

@ACuriousMind The next problem is to examine the spin of a massless particle assuming the invariance group is $\mathrm{O}(2,1)$.

@DanielSank is this the operator you are talking about? the one we put the sqrt in front of?

@all what do I need to bring to college

@TanMath can you link your question again please?

@0celo7 Ah, now that could be potentially more interesting, although it probably will still not be quantized because the universal cover is still not a double cover

@TanMath, suppose we have a two level system.

The lowering operator is $a$.

@ACuriousMind wait, why does the double cover mean quantization?

is that the topological constraint?

In this case, the Lindblad operator associated to energy decay process is $L = \sqrt{\gamma} \, \hat{a}$, where $\gamma$ is the decay rate.

because of the $4\pi$ rotation business?

@DanielSank I actually need to get going... You can continue to write this out.. I will come back and look at it.. Thanks! also thanks @0celo7 and @ACuriousMind !

@0celo7 Ah, it doesn't mean that directly, but the infinite cover means we get a lot more reps than usual.

It's a heuristic statement, I admit, but that's why I said "probably"

now to find the little group...

uh, no clue what it is

we Lorentz boost to $k=(1,1,0)$

then what is the most general $W$ such that $Wk=k$?

Give me an hour or so to shower and go shopping, then I'll take a closer look at this.

I need to pack!

I have no clue what to pack!

I need to get food!

@ChrisWhite Tellin' it like it is.

ennui? googling

wow

speaking from experience there?

I don't even have any posters.

@0celo7 Then you fail college.

@DanielSank that's not good

@0celo7 your love of learning and understanding

that got killed by HE

what is "HE?"

@0celo7 seriously though, take your basic home needs and typical school supplies. You have to take care of yourself somewhat more than at home so once you get there go out and buy laundry detergent etc.

@0celo7 are your goals primarily academic or social?

@DanielSank academic

@DanielSank I'm going on a Costco run when I get there for all that stuff

are you going to join a frat?

@0celo7 Are you sharing a room?

@DanielSank yes

@0celo7 Ok, honestly, bring ear plugs.

Hopefully you'll never need them.

^

@DanielSank Why would you not always bring ear plugs

I have a supply in my suitcase

@DanielSank my roommate will

@0celo7 Why's that?

@DanielSank snoring

@0celo7 Ha, I pity your room mate.

we Ungers have been champion snorers for 4 generations

@0celo7 ::applauds::

@ChrisWhite Is this more difficult in America than walking into a store and buying it? Are there special laundry detergent stores whose location is passed only through oral tradition?

@ACuriousMind Not that you know of.

@ChrisWhite my siblings are lifelong friends with their roommates, and my parents' roommates were so bland they can't remember their names

@0celo7 The problem is that room mates can ruin your life.

@ACuriousMind if you don't have a Costco card you have to Sam Fisher or Altair your way in

Emphasis on "can".

how?

I talked to mine, he seems cool

@0celo7 Being loud, messy, emotional wrecks, etc.

he loves Skyrim FWIW

But mostly by having different expectations than you about how to exist in a shared space.

^that

Wow.

Our freshman year room mates were chosen for us.

This worked ok, but there were some issues.

I got in a lottery with someone else in honors

@ChrisWhite gross

oO

I believe you mean o_O

@DanielSank like?

@DanielSank Oo

@0celo7 Ehhhh, one of my freshman year room mates just didn't like us.

I just have on person

There were four of us in a suite. One of them just didn't get along.

I'm in the new dorm, first one to ever live in it

@0celo7 NICE!

I was in a pretty old crappy building :)

we have a Subway (sandwich shop) in the lobby

a water fountain

key card locks on the doors

@0celo7 Oh no.

oh no?

I'm calling it now, guys. Within two years @0celo7 will be unable to look at, smell, or even think about Subway without needing to run to the nearest rest room to boot.

@ChrisWhite I lost 10lbs my freshman year.

My mother is a wonderful cook. The college food was not bad but I lost weight.

apparently people tend to lose weight because the campus is built on the side of a mountain

@0celo7 Ha, nice.

@0celo7 lol

If I had lost weight, I'd probably be dead, I'm stick-thin as it is.

luckily my lit class got moved closer to the stadium and now I don't have a run a mile uphill both ways in 15 minutes

@0celo7 Both ways in 15 minutes? Explain.

how can you run uphill both ways?

@skillpatrol ...unless you grew up in the old days.

Back "then" they had two way hills.

:D

@DanielSank you have to run a line integral

the college is a multi-valued complex function you see

you go on a new branch every time and it's always uphill

Your college was built by M.C.Escher?

lol

no MC Hammer

Hammer Time!

gotta go say bye to friends and family

later

@0celo7 Yes!

I wish I gained weight my first year

or any year for that matter :p

I think being in good shape is more important.

that's too much work

I just don't want to be skinny :p

but at this rate my only hope is to wait until my metabolism slows down at the age of 30

@ACuriousMind so you really are a skeleton

fat people have more health issues

@FenderLesPaul just eat more...

@0celo7 it doesn't work I've tried

it's just genetic I think; my brother has the same problem

Yeah right

I could eat a shit ton of meat every day and not gain any weight

You can get bacon grease

in fact that's what I do

bacon is like my best friend

10,000 calorie diet

murrica

ok I don't wanna die lol

I would go to the gym if I wasn't lazy

I paid $90 for a semester membership and went literally once

right there is your problem

You could have bought some video games with that money

@0celo7 I know :(

exercise will slow down your metabolism

I regret not using that money on useful things

could've bought more bacon

but like...exercise is so much work

true

I need stronger motivation

bacon is work too, you gotta buy it, bring it home, cook it, eat it, poop it

right now I have no driving motivation to work out

girls go ther

once your health fails you, you will change

@Jon all enjoyable things

that could take decades

@skillpatrol idk what a girl is

By the time you wanna change, it will be too late

-_-

decades of bad habits

@jon but by then I will have lived a long and bacon filled life

@skillpatrol but in all seriousness I would need a legitimate motivation

health would be one but it's so hard to use health as motivation when that's not an immediate problem

That is why I mentioned that you would only do something about it once it becomes a problem, trying to speed up the conversation

Your motivation should be, to not wait

do it just enough to stay in shape

Alright time to speed up the health deterioration process

eat a pack a bacon a day

thus forcing me to work out

honestly when I get home from work I just wanna play guitar, watch random shit on youtube, eat cereal, and then knock out

BACON

add whiskey and smokes

hmm that would work

although smoking would ruin my singing

Get Intervention to do a segment on you

maybe I can go on "America's Biggest Loser" or whatever it's called

but it would be a plot twist cuz im really skinny, not really fat

i contemplated faking an addiction to get on intervention

My name is Jon, and I'm a full blown alcoholic.

LOL

Then just go on a tear while they film me for a week.

"I'm addicted to Bacon"

"Sir, why is bacon capitalized?"

"Bacon is God"

crazy eyes

@Jon whiskey is great

You don't have to tell me

@0celo7 don't forget to bring Weinberg G&C

you're going to need it to prepare joints

@FenderLesPaul I thought Wald had really good paper for that

But Wald has other uses too

paperweight?

cat scratching toy

makeshift pillow

@0celo7 Yes, I'm a vampire skeleton.

@ACuriousMind holy shit I need to see that for myself

I'm returning to the fatherland this Christmas

I need a name for my game

anyone clever here?

yes

me

pick me

I'm making a physics puzzle game

elevator pitch -- Red/Orange are evil -- Green/Blue are good

interuniversal teichmuller twistor mechanics

on principal braid bundles

It would need to be a little more simple, going for a all audience

I'll take the royalty check in Subway gift cards

lol

what's the objective?

do mechanics in a very complicated way

ask ACM in a few years, I just gave him the title of his PhD thesis

@0celo7 Teichmüller twistor mechanics you say? Hmmm....

objective is to get rid of all red and orange pieces on the screen

While retaining all the green

There is a older preview build up here jgallant.com/Preview/Preview.html

the tutorial isn't in that but you can get a general idea of the gameplay

how is this related to physics?

physics game

if you could make that link clear, you could use it as a name

Yeah, that is exactly what I had been trying to think of.

Do they allow game naming questions on Stack Exchange?

haha, I really don't think so

we should try to promote a new SE site specifically for that

area 51?

Game Naming.SE

or ask on meta at Arcade.SE

Block Potential

sounds good :-)

Drop Point?

that is pretty good

damn i'm pretty impressed how this stackexchange is creeping with grad students instead of cranks.

Are $\{\text{grad students}\}$ and $\{\text{cranks}\}$ disjoint?

not always. knew a grad student trying to explain chakras with quantum mechanics.

@0celo7 I have to start worrying about that as well, but luckily I have an obsessive mom that's compiling a list for me... All your toiletries, office equipment (laptop, printer, paper, pens, etc), bedding, and all essential documentation (birth certificate, passport, etc). Oh, and of course your fake ID as Chris mentioned.

I'm also going to take a mini-bar sized fridge to put in my room, as I won't be able to have a kitchen to myself.

hello @DanielSank

quantum [insert word here] makes [insert word here] infinitely more legit

@Jon reminds me... have you ever heard of a game called "crazy machines"? luv it, really fun, teaches a lot of physics, sophisticated physics simulation engine, etc :D

@mathdummy & how about explaining QM with solitons instead? :D

@TanMath Hi.

@vzn is it still downloadable?

if I click on the buying option it says page not available

Guys, I just did a calculation to answer this question, but I don't understand the result.

@FenderLesPaul hmmm, afaik its typically in app stores, they say its released on android... have it on iphone & ps3, but bought it awhile back... highly recommend it... very good for kids too...

Why does the error get bigger when computing a derivative from points closer together in time?

@vzn cool thanks! If it's on iPhone I can get it on that.

@JamalS (wondering) did you mention in here how that worked out or where you picked?

@mathdummy agreed, now if only a few would hang out in Computer Science or Theoretical Computer Science occasionally too :D
