why for experiments related to general relativity we always use a photon clock not any other type of accurate clock?

0celo7

So JD can have fun

Slereah

Not always a photon clock

Sometimes it's a cesium clock or such

The mechanism doesn't matter

0celo7

@Slereah Wursts are fucking amazing and the only problem with America is the lack of German meats

Slereah

I went to a McDonalds in Germany, they had wurst burgers

0celo7

Bull

How did you talk to them

Germans don't speak French

Bernard Meurer

16:03

@Slereah You french?

Slereah

Yep

sharaf zaman

@Slereah yes mostly they use photon clock

Bernard Meurer

@Slereah Omelet du fromage

Slereah

@0celo7 : I know the magic words

Hallo

Danke

Tchuss

sharaf zaman

lol!!

Slereah

16:04

It works for most business transactions

Bernard Meurer

It's like me in Denmark, the strategy is say "Tak" and "Jeg elsker dig" to everyone

the latter actually got be some free fruit

Slereah

I can also do my standard McDonald menu in german

Eine grosse pommes, neun nuggets und ein sprite, bitte

Bernard Meurer

@Slereah I want to see you say that now

0celo7

Nine? Lol

Slereah

Es ist zeit fur Rache

0celo7

16:06

If you're not getting 20 what's the point

Slereah

Nine is actually the most you can get in most places in Europe :p

0celo7

Holy shit what

I wasn't kidding, 20 is normal here

Slereah

I know

I've been to the US

I take only 6 nowadays if I go :p

0celo7

O.o

Does subway sell footlong sandwiches in Europe?

Slereah

Maybe, I dunno

Also

The large drink at McDonalds is ONLY 0.5 LITER

0celo7

16:09

i don't remember Europe being so shit

Bernard Meurer

@Slereah That's just ridiculous now

I need at least 1L

0celo7

I can get a .75 L from the vending machine down the hall

Slereah

I wonder how the giant americans do when they visit Europe

0celo7

im not giant

But that shit is tiny

Slereah

YET

Just stay a few more years

See what happens

0celo7

16:10

When I was on my trip this winter we only went to places that served a lot of food

I guess

Slereah

You're gonna reach the Chandrasekhar limit

sharaf zaman

haha!

Slereah

Speaking of America

I should try a reindeer burger before I leave

0celo7

What does that have to do with America

Slereah

BURGER

Bernard Meurer

16:14

@0celo7 You're pretty giant

0celo7

Wtf

Are you calling me a fatass

That's not very fucking nice

@Slereah disregard him.

@Slereah huh?

Bernard Meurer

:)

0celo7

@BernardMeurer do you really think I look like one of the WALL E people

Bernard Meurer

@0celo7 No, but you're p tall

0celo7

Meh, 6'3" with shoes

user116211

16:24

@0celo7 pretty tall

0celo7

But I'm not "giant"

sharaf zaman

haha!

0celo7

Why do you always laugh

Bernard Meurer

haha!

ACuriousMind

@Slereah You can get the 20 pack, but they look at you funny if you order it :D

sharaf zaman

16:27

no! the chat here is interesting and funny!! @0celo7

@Slereah Chandrasekhar limit was awesome one!!

0celo7

@ACuriousMind I was quite a bit smaller when I lived there

But we never went to McD anyway

@ACuriousMind you get three guesses as to which counterexample my prof is using for "not all cont. functions are differentiable"

ACuriousMind

Absolute value.

0celo7

We have a winner

Slereah

@ACuriousMind Well the 20 pack in Europe is supposed to be a family thing, I think

Not for one gigantic fat man to eat it

0celo7

Should I tell him it's not very satisfying ;)

@Slereah lol

Could be a fat woman, too

Or a normal sized person

Slereah

16:34

The fat woman will take a salad tub filled with mayonaise

and a diet coke

0celo7

@Slereah I'll drink 1-2 liters of Coke Zero with my meals

Actually that's a bit much

1L is normal though

ACuriousMind

The Murican consumption of soft drinks as if they were water is also alien to the European :P

Slereah

Reindeer burger tastes fine

0celo7

Ich weiß, aber die Amis know the good shit

Slereah

Although I fear Santa won't bring me any presents now

0celo7

16:37

I've never understood why people make fun of fat people for drinking diet stuff

There's a crazy amount of calories in sugary drinks

Slereah

Because they eat a box of 20 nuggets and a diet coke

Somewhat misdirected effort

0celo7

How many calories is in that box?

Slereah

20 nuggets? Fuck

0celo7

I've put away 20 a few times in my life, but I've been significantly cutting calories.

Slereah

My box of 9 I think is already too much

Bernard Meurer

16:39

@0celo7 Want to ungiant?

0celo7

@BernardMeurer what?

Slereah

863 calories for the box of 20 nuggets

That's like almost half the recommended calories input

0celo7

Ok, so that's fine

Wow I'm gonna get a box when I go home

I thought it would be a lot of calories

Slereah

>not a lot

>860

0celo7

For a meal?

Yeah, that's not a lot.

Slereah

16:41

Reminds me of the people saying that the basic human caloric intake is 2800 calories per day

It's fine for a meal, if you only eat that

0celo7

Exactly

And like 10 things of BBQ sauce, of course.

Slereah

Isn't barbecue sauce basically sugar :p

0celo7

Probably.

@BernardMeurer Basically my doctor said I'd kill myself if my metabolism weren't crazy

Slereah

Delicious reindeer

0celo7

Omg is that you

Slereah

16:44

It is

0celo7

I don't believe it.

Do the Spock hand thing

Slereah

Then don't

Probably shouldn't have had it, since I still need to have dinner with the Team afterwards

But I just wanted to say that I've had a reindeer burger :p

0celo7

So?

ACuriousMind

@Slereah ...are you eating a reindeer burger while wearing a plushy reindeer hat? :D

0celo7

Eat more

Slereah

16:45

I am

0celo7

You Europeans are weird

Slereah

@0celo7 reaches in his Jabba the Hutt vat of frogs for a snack

Oh wait, did @0celo7 even see Star Wars

Or is that another of those movies he never saw

ACuriousMind

I think he saw them, but didn't like the original ones

::shakes head sadly::

Slereah

I was never that big into Star Wars myself

I mean, they're not bad movies

They're fine

But it's not a thing I'll get into a fandom for

0celo7

I saw the newest one, went with my dad and neighbor, then I went w/ gf on a date

The originals are boring

Slereah

16:48

Newest one was fine, too

0celo7

I like the prequels

Slereah

Although waddling a bit too much in the original movies, too

0celo7

@Slereah You know there is a sandwich shop with 1200cal sandwiches

Slereah

Probably

0celo7

Add chips and a sugar drink and you've got your daily calorie intake

@Slereah I've been there a few times, I get the 1000 cal salads

Slereah

16:51

How do you even do a 1000 calories salad

How much actual salad is in it

0celo7

Lettuce and shit. I dunno

Slereah

My salads are like

Lettuce, lemon juice and a dab of oil

0celo7

Lemon juice?

Slereah

That's like 50 calories tops

Yeah

p. tasty

Although

Terrible for my teeth

Acid in my mouth every day isn't good for enamel

0celo7

My salads: lettuce, kale, spinach, carrots, corn, peas, black beans, kidney beans, mushrooms, chickpeas, olives, croutons, sunflower seeds, jalapeños and turkey.

Slereah

16:53

That's a lot of shit in salad

Sometimes I put little chicken bits for fun

0celo7

Yes. They're pretty good.

Slereah

But I do love my lettuce

Iceberg lettuce

Best lettuce

0celo7

Romaine or GTFO

And kale is way better anyway

Slereah

Iceberg lettuce is so crunchy, tho

ACuriousMind

I prefer Feldsalat (no idea what it is in English)

0celo7

16:54

@ACuriousMind Look it up?

I don't know either

Slereah

Valerianella

Valerianella is a genus of plant in family Caprifoliaceae. Many plants of this genus are known by the common name corn salad or cornsalad, although that name most often refers to Valerianella locusta. Here is an incomplete list of its species: Valerianella affinis, Balf.f. (believed extinct) Valerianella amarella, Hairy Corn Salad Valerianella carinata, European Corn Salad Valerianella chenopodiifolia, Goosefoot Corn Salad Valerianella dentata, Narrowfruit Corn Salad Valerianella eriocarpa, Italian Corn Salad Valerianella florifera, Texas Corn Salad Valerianella locusta, Corn Salad, Lamb's Lettuce...

This, apparently

0celo7

Wasn't a lettuce expert back in the day

Slereah

Corn salad

ACuriousMind

@0celo7 Does "corn salad" sound right to you?

Slereah

Cornhole salad

Bernard Meurer

16:55

We didn't evolve all the way to the top of the foodchain to eat the same stuff a cow eats

0celo7

@ACuriousMind lol

Bernard Meurer

we should only eat lion meat to show who rules

Slereah

I do love my meat

I basically eat steak as often as I can

0celo7

At home I'll put filet in my salads

Slereah

Know what else is great?

Potatoes.

Potatoes are pretty magic

ACuriousMind

16:57

@BernardMeurer Although meat is delicious, there's nothing wrong with a meal without meat.

0celo7

@ACuriousMind lol

Slereah

Baked potatoes are gr8 because they are delicious and you basically don't need to do shit

I just stick the potatoes in the oven and let it work its magic

Then I put some butter and salt

Bam

0celo7

I like boiled potatoes with ketchup

ACuriousMind

@0celo7 What? Does that sound too much like innuendo?

Slereah

I don't even need to dirty a pot or pan

0celo7

16:58

@ACuriousMind no, it's a lie.

So blatant, too.

Oh wait, I never eat meat at breakfast

And my favorite food is meatless

Slereah

I bought some meat snacks at the lapland supermarket

0celo7

I take it back.

Slereah

little bits of dried reindeer meat

0celo7

I didn't even think of it as an innuendo, you sick man

Slereah

Looking at the ingredients

Reindeer 98%

ACuriousMind

16:59

@0celo7 No, it's not. I don't put meat in my salads, and I also like to make tofu sometimes.

Slereah

Salt 2%

ACuriousMind

@0celo7 lol

Slereah

My kind of snack

It's not like jerky shit where they try to put in sauces and spices

0celo7

@ACuriousMind what's funny

On mobile

DanielSank

@0celo7 Then why'd you give me crap about my chili being meatless?

Slereah

17:01

Blah, meal with the team in 30 minutes

To do some more "Team building"

0celo7

Just because there are good meatless things does not make it a good idea to make all things meatless.

ACuriousMind

No one said that

0celo7

I'm responding to Dan

Slereah

So anyway

I wonder what is the Lagrangian formulation of Aristotle's mechanics

0celo7

@DanielSank the veggie foods I like are not made better by meat

But chili is made infinitely better by meat

So you're a criminal for not putting meat in the chili!!

Slereah

17:06

Obviously since the force depends on speed, the Lagrangian will not depend on derivatives

And since it is geocentric, it will not be translation invariant

0celo7

What are you talking about

Are you high?

Slereah

Aristotelician logic

Hm

I don't think Aristotle believed in atoms, so no point particles

The Lagrangian will be 4 fields

Fire field, water field, earth field and air field

The water and earth field must both go towards the center of the universe, while the fire and air field must go away from it

BUT WAIT

Ether limit

What happens there

ACuriousMind

I think the reindeer burger might have been bad

Slereah

Psh :p

Do you never wonder about outdated physics

0celo7

I wonder about QFT all the time.

ACuriousMind

17:09

not really

Slereah

I still don't know why a classical blackbody would diverge

I mean, I know the argument

But consider it as a simple collection of charges

Obviously it can't radiate away an infinite energy

The system has only a finite amount of energy

0celo7

@ACuriousMind all you do is QFT!

Slereah

Would a proper analysis of classical blackbodies actually have a UV divergence?

Leaving aside any issues due to EM fields for point particles and such

ACuriousMind

@0celo7 What are you trying to say?

0celo7

QFT is outdated.

Done, kaput.

ACuriousMind

17:12

@0celo7 And has been succeeded by what?

Slereah

Obviously @0celo7 is all about AQFT

No more operator valued distributions!

Or distribution valued operators

Now it's all functors

0celo7

Strings.

And GR, of course.

Slereah

Strings are still quantum, @0celo7

It's still Hilbert space shit

0celo7

So?

I think that burger was poisonous

Slereah

Oh bother

Laptop can't read the camera's SSD card

I can't show the giant fucking snow walls

0celo7

17:17

@ACuriousMind thinks I'm a troll

Slereah

Well, aren't you

0celo7

Not really.

Slereah

What's the equivalence between string theory and QFT, anyway

How do you represent a scalar field in string theory

0celo7

No one knows.

Slereah

In what approximation does it work

Is it like

Polyakov???

I know Polyakov is the "Bosonic string"

ACuriousMind

17:19

@Slereah The"low-energy" effective theory of ST is supposed to be a QFT. What the particle content is depends on the geometry of the target space ("compactification"). Don't ask me for details, I sadly do not know them.

Slereah

Well let's say basic strings on Minkowski space

Is it equivalent to something

ACuriousMind

No, certainly not equivalent to a QFT.

Slereah

Hm

What would be the equivalent to a basic free scalar field

Do we have a string expert

ACuriousMind

You have this infinite tower of "level n excitations" that just doesn't appear in a QFT

Slereah

Will the real string expert please stand up

0celo7

17:21

There are none.

ACuriousMind

@Slereah The space of string theories is much more confined than the space of QFTs - every ST has a low-energy QFT, but not every QFT has a corresponding string theory. (if I understood someone I talked to about this once correctly)

Slereah

What's the simplest example then

I wanna do the strings but damn they are not friendly to newcomers

Even the intro on Polyakov strings isn't an easy read

0celo7

Do strings have any GDP applications?

Slereah

Yes.

String theory has application in solid state physics.

0celo7

Really??

Link?

Slereah

17:23

Yes.

ACuriousMind

@0celo7 AdS/CFT is exactly that.

Slereah

That's what the dummies that decry theoretical physics don't know

The math always has a use outside

0celo7

@ACuriousMind it's exactly what

ACuriousMind

@Slereah I don't think there's a "simple" example, and that's why no one gives one. You have to step through the whole compactification business to see how the low-energy 4D QFT is generated.

@0celo7 The correspondence of certain solid state systems to certain string systems.

Slereah

Oh well

7:30

I'd better go in the lobby and be social

0celo7

17:26

@ACuriousMind interesting solid state?

ACuriousMind

No, all solid state is boring.

Slereah

On the other hand

beaucoup GDP

Solid state physics is the big bucks for physics

Solid state physics, thermodynamics, fluid mechanics, optics and electronics

The GDP fields

Q: Green Function for curl with wall problem - References

I was looking for the Green Function of the following problem, on the upper half plane: $ u : \mathbb{R}\times \mathbb{R}^+\rightarrow \mathbb{R}^2$, $\mathbb{R}^+$ corresponds to the non-negative positive real axis. $\omega: \mathbb{R}\times \mathbb{R}^+\rightarrow \mathbb{R}$ prescribed $\pa...

Off-topic?

Slereah

not too much, but veering on homework question

0celo7

@ACuriousMind just like QFT and algebra and category theory

ACuriousMind

17:30

@Qmechanic It's not really a resource-recommendation question as we understand them here, for sure. And I would say such questions that are just about solving some equations without giving physical context should better go to math.

Qmechanic

@ACuriousMind : That's what I'm thinking too.

Slereah

Phone chat is still a bit shit

Doesn't always display properly

0celo7

It's pretty bad.

ACuriousMind

@Qmechanic I can't vote on it though; I've my close votes for the day

Bernard Meurer

They should just make a phone app

instead of wasting time finding more uses for 3D touch

Danu

17:38

Is that message by Qmechanic pinned on purpose? It doesn't make much sense to pin it, to me.

ACuriousMind

@Danu Qmechanic often pins things that he wants to get opinions on, and unpins them after he's heard enough

Danu

Okay.

You know what sucks? Coming home and finding out there is no heating.

Typing with gloves is surprisingly easy, though.

ACuriousMind

@Danu lol. In Munich?

Danu

Yeah.

ACuriousMind

I hope someone is already repairing it?

Danu

17:40

Not until tomorrow.

:(

Some important piece was broken

ACuriousMind

Whaaaaaat? That sucks indeed :/

Bernard Meurer

We get natural heating down here

It's very close to hell you see

Slereah

Eh fuck it

Not eating with the team

Danu

I'm basically freezing my toes off now :P

Slereah

Not hungry

Already full of reindeer

Bernard Meurer

17:42

@Danu Try to fold yourself?

ACuriousMind

@Danu Play some graphic-intensive game and let your computer heat the room ;P

Slereah

Play some Farcry

Or just run a big map of Dwarf Fortress

ACuriousMind

Oooh, I haven't played DF in ages

Slereah

Now you can make books!

Currently useless tho

Also you get fortress immigrants that aren't dwarves

Mostly soldiers and musicians

Bernard Meurer

HA, MY PROJECT WORKS

Slereah

17:49

Sneaky move, advertisers, to try to intrigue me before youtube puts the "skip this ad" button

But the thing is I always skip the ad, EVEN IF INTRIGUED

I know it is just one of your dirty marketing tricks

ACuriousMind

@Slereah Do non-dwarfs have advantages? Do they get moods?

Slereah

Not sure, didn't really notice any

The big advantage is that you get soldiers easily with a tavern

ACuriousMind

Do they consume alcohol as much as the little buggers?

Slereah

No need to scrap a heapful of shearers and cheesemakers into an army

Just like in real life, DF armies are made with the least useful members of society

"I specialize in pottery glazing!"

Into the army you go!

Bernard Meurer

Actually it didn't work and it crashed the whole device

Danu

17:59

very helpful guys :P
