The h Bar

hola

19:00

how does magnetic field look like in a square loop of wire carrying current?

Phase

@CooperCape idek if @0celo7 knows when he's joking anymore

@hola use Biot Savart

0celo7

just solve the Maxwell equations

CooperCape

h bar is confuzzlin'

hola

i know the wire produces circles around the wire but at the corners what happens there

??

Biot- Savart doesn't tell me how it looks in the corner

Balarka Sen

@CooperCape Same

hola

19:01

do the magnetic field circles stop suddenly at the corners?

0celo7

@Phase The looks on liberals' faces when the internet goes down...will be priceless.

Balarka Sen

His humor is layered with a thousand levels of irony

so much that it's impossible for even me to tell if it's genuine or not

CooperCape

0celo played the 1000 layers challenge forever.

hola

cmone guys focus!

0celo7

@hola no

CooperCape

19:02

Iss a confusin' world

Phase

I think @0celo7 has stared too deeply into the abyss

0celo7

I am the abyss.

CooperCape

@hola Juss saying Idk what you chattin about so I can stay firmly off course

Phase

Oh shit

Soon he'll be going to Hot Topic

and rebelling against @ACuriousMind

...more

0celo7

I already wear emo clothes

CooperCape

19:03

@0celo7 Do they have more rips than fabric? :p

Phase

@0celo7 does it have spikes on it

0celo7

no, ripped clothes are degenerate

@Phase no, don't want to be arrested for assault with a deadly weapon

Phase

I wasn't aware you too lived in the UK

There's an Essex Police page and they've been running a campaign basically saying "it's illegal to have replica guns or knives so bring them to us"

hola

In a wire square loop carrying a steady current. I know that the current creates magnetic field circles around the wire at each side. But how does the magentic field look like at the corners??

or outside the square

Balarka Sen

@Phase To be fair you have to have a very high IQ to write a long message pertaining to a Rick and Morty meme. Posting the full-length message requires extreme care and without a solid grasp of theoretical physics it is impossible to fit the full text inside the alloted space in the stack exchange chat.

hola

19:06

will there be circles of magnetic field in a line lining up with each side?

Phase

@BalarkaSen dont joke about that mane :(

CooperCape

Don't have enough RaM

Phase

Nice.

0celo7

I don't think phase understands the subtleties of spectral theory, hence cannot appreciate Rick and Morty.

good night

we need to learn from our mistakes to ensure something like that never occurs again.

Phase

19:10

@0celo7 I don't think you understand the subtleties of $sin(x) = x$ for all $x$

good night

we deserved better than this.

we're better than that.

0celo7

@Phase that's a false statement!

Phase

Just squint and it becomes approximately true

Balarka Sen

@hola I think the overall picture would look similar to the magnetic field of a circular loop. You can compute the field by hand, can't you? You'd have circular field lines going around each side of the square carrying the current cylindrically. However there indeed would be some sort of discontinuity at the corner points, I am guessing

0celo7

only a physicist would do that

@BalarkaSen reality is $C^\omega$, how could it be discontinuous

Phase

19:12

Honestly I don't think Mathematical Physics will give me the rigour I'm looking for so

I'm gonna convert to mechanical engineering

ACuriousMind

@Phase What is the rigour you're looking for?

good night

that can get quite rigorous with the fluids

Phase

@ACuriousMind mathematical

so mech eng. >>> physics >>> maths

enumaris

Wut

ACuriousMind

@Phase No, I mean, why are you looking for rigour?

good night

19:13

only mathematicians who didn't get into mechanical engineering but refuse to accept the reality can understand.

Anonymous

@BalarkaSen Yeah, that's called called fringing effect iirc. It depends on the medium (the pattern)

Balarka Sen

@Blue Oh nice

Anonymous

It's a complicated thing

Anonymous

I don't know if any accurate model exists

Anonymous

There are only approximations

good night

19:14

@ACuriousMind the irony

:p

Phase

Because I don't want to learn things in a shallow way. to be serious for a second, until I get to the point where I feel like I have the capacity to rigorously learn the things I want to learn, I won't feel like I have any worth as a h00man bean

hola

So the circles stop being produced at the corners and do not continue in an infinite line with the wire.

Balarka Sen

That is interesting, I did not know that. I was wondering what could happen at the corners

Phase

I dont wanna get to the end of a Physics degree and be like "what's an isomorphism"

Anonymous

@Phase wut

good night

19:15

@Phase but the shallow way is fun that's where all the kids are

Phase

[REDACTED]

wait

good night

spacey?

Balarka Sen

lmao

Anonymous

@Phase I think you are assuming that all physicists are non-rigorous.

Phase

@Blue I'm talking about the courses at my Uni

Anonymous

19:16

Mathematical physics is usually a part of the math department for a reason

ACuriousMind

@Phase Things that are not rigorous are not necessarily shallow. There is value in rigour, but progress in physics is often not made by adhering to rigour - we blunder ahead, and care about rigour only later. I stand by what I said a while ago:

May 4 at 19:39, by ACuriousMind

If there are inconsistencies, but they can be avoided on the basis of physical reasoning, I think it's totally fine to split into two camps - those who want a better, consistent, rigorous foundation and those who push on - as long as the theory is consistent with experiment - and see what else they can do with that. I actually think that a large amount of physical progress has been achieved by these two camps keeping each other in check.

Balarka Sen

Absolutely agree with this ^

good night

guys

skullpatrol

wut

Phase

Yeah but @ACuriousMind I came to the realisation a while ago that not only do I only really care about the maths, it's all I really like

good night

19:18

check out the mathematical physics group at my university

Anonymous

@Phase Huh, then I don't know why you spoke about mechanical engineering

Balarka Sen

That's basically why I said physical and mathematical thinking are different a few hours ago

Anonymous

lol

good night

they're kinda shy but it's alright

0celo7

that seems like an empty page

Phase

19:18

@Blue it was a joke : P

good night

@0celo7 :p

0celo7

@ACuriousMind What about the third camp -- those theoretical physicists who are completely out of touch with experiment but also nonrigorous?

Phase

@0celo7 string theorists?

im sorry ACM don't hit me

0celo7

for instance

good night

@0celo7 JD?

oh you said theoretical physicist my bad

ACuriousMind

19:21

@Phase That's fine. I'm just cautioning against arguing one approach is really objectively superior to the other

Phase

@ACuriousMind I didn't think I was, I thought I made it clear that I just personally wouldn't be able to respect myself without understanding properly the various parts of maths

ACuriousMind

@0celo7 I think those are genuinely very rare. If you are alluding to string theorists, a lot of string theory - string phenomenology - is trying to produce stringy models that yield something like the Standard Model, or otherwise get testable predictions

Anonymous

@Phase Do a double major if possible

0celo7

@ACuriousMind But what about the area you were working in

skullpatrol

What "camp" are you in?

0celo7

19:24

@skullpatrol Rigor above all.

good night

base camp

was in summer camp several years ago but people change

ACuriousMind

@0celo7 That was string pheno - in an early stage, but the reason people are interested in these $G_2$-models is because they can produce SM-looking gauge groups, SSB, etc.

skullpatrol

Remember the user named "rigor"? @0celo7

Phase

@ACuriousMind when do you start your job as lead AI of Skynet?

ACuriousMind

January, probably

skullpatrol

19:27

Wow! So soon?

Phase

i wish you extremely good luck

ACuriousMind

Thanks, I will remember it once I have achieved world domination :)

Anonymous

He is too clever not to mention the year :P

Phase

If I wish you enough luck will you spare me when you enslave the humans?

Please?

ACuriousMind

We'll see.

0celo7

19:29

Don't worry, I have a plan in place.

I know some people in Heidelberg.

Balarka Sen

Does ACM run via machine learning and neural networking?

Phase

I know how to defeat @ACuriousMind

Balarka Sen

Or has he found out a more efficient technique?

skullpatrol

Deep learning :P

ACM: "Any last words human"?

"LetMeLive!'); DROP TABLE RICKANDMORTYEPISODES; --"

Mithrandir24601

@0celo7 ... So do I...

Phase

That would reduce him to a calculator level in seconds

Balarka Sen

ACM's downfall lies in communism

ACuriousMind

Oh, code injection. How cute.

Phase

@BalarkaSen you would say that

@ACuriousMind it's all we can hope for

skullpatrol

19:34

Thanks @Blue :-)

Balarka Sen

through communism the proletariat will unite and abandon the use of capitalist objects such as machines and computers

Phase

@BalarkaSen and food

0celo7

maybe can just GULAG it

good night

19:44

get ur life and go

dear editor, i don't appreciate @ACuriousMind's icey betrayals

we go way back

skullpatrol

let it go, pal :-)

good night

i like to believe that acm is being ironic by censoring the chat

ACuriousMind

@goodnight Sorry, but: What? I'm not betraying you, merely holding you to the same standards as everyone else in this chat, as is my duty.

good night

deep down

@ACuriousMind that's communism in a nutshell right.. @BalarkaSen

please confirm

skullpatrol

Enough with the trolling...

Phase

19:53

Or else ACM will banish you to three other dimensions

good night

extraordinary claims require extraordinary evidence

ACuriousMind

@goodnight No, it's justice. I'd be a terrible hypocrite if I treated you differently because I've known you longer than others.

good night

dont talk like u know me cos u dont know me

@skullpatrol ^

skullpatrol

::makes popcorn::

@goodnight^

good night

popcorn has bones @BernardoMeurer would be disappointed

Phase

19:57

@ACuriousMind how long do I have to know you before I can cash in my known-you-for-long-enough card and get my loyalty rewards like immunity to consequences

ACuriousMind

@Phase Since birth.

Phase

shieeeeet so basically I gotta be your mum?

ACuriousMind

yup

Or my long lost twin, I guess

Phase

Hey @ACuriousMind you'll never believe what news I got the other day!

good night

@skullpatrol how did it feel when your publisher dropped your latest book series in cold blood

Phase

19:59

They reckon my real parents can be tracked back to germany, they realised something was up when I started coughing and spurting out random bits of code

good night

you should do an AMA
