@ACuriousMind help

I want the radiator fan to push air into the case, right?

Cold air from outside the case into the case, through the radiator?

Mmmh, don't you have some ventilation slots for that?

A radiator fan should exhaust warm air, imo

Ventilation slots?

Might also have intake fans

I have exhaust fans near the mobo

I think I only have exhaust fans, the air intake is through slots, not fans

Where is the damn manual...

I have no idea where the manual is

according to the Corsair website, the water cooling fan should be an intake fan

I assume that means the arrow should point inwards

I'm also not 100% sure it really matters as long as your intake/exhaust is balanced overall

@ACuriousMind Damn. Is PCI-e fine to take out?

I have to remove the GPU to get to the fan plug

Uh?

I don't want to be responsible for you bricking anything so I'm reluctant to say anything definitive :D

I don't actually know a lot about the hardware side

luckily for you I was able to remove another side panel

@JohnRennie Welp, temperatures are higher now.

@ACuriousMind should I redo the thermal paste?

ah, the ever helpful tech forums

@JohnRennie According to the interwebz, the 1600X has a 20C temperature offset.

@JohnRennie fuuuuuu

the AMD overclocking tool has the right temperature

@SirCumference ...you realize you just replied to a month-old message, right? (Just checking)

Holy crap, it's not june...

thanks for the reply, I do appreciate it.

even though it was a month after the fact. there was no need to delete it.

@SirCumference You tired again? ;P

But I think you should keep this in mind. Wait until junior or senior year before thinking about what college you want to attend. I had my heart set out for one back in freshman year but later explored and found the perfect match for me

okay.

@ACuriousMind Yeah, not enough sleep :/

Spent all of last night worrying about a test, found out in the morning it was postponed

ouch. what's the test on?

@heather Astro

well, at least that means you can get sleep/more study time before the test.

BTW, I'm wondering (for any physicists here). Should I consider double majoring in math and physics if I want to learn GR?

I've only really touched the surface of it, and I know it requires a ton of math

Yes. GR is arguably more mathematics than physics.

;-;

This is gonna be rough

@0celo7 @JohnRennie Any opinion?

@SirCumference I don't quite see the connection between physics requiring math and having to "double major", but I don't quite understand the American concept of undergraduate studies, anyway :P

Imo, you'll be much better of learning specific math if and when you need it instead if your sole interest in math is for physics' sake

Well, presumably having as strong a grasp of math as possible will help with GR, right?

@SirCumference Well most of math is pretty useless for GR :P

@SirCumference one thing to consider is that the number of math classes you need to take to reach the prerequisites for the GR classes you want to take may very well lead you close enough to the requirements for a math major that it wouldn't require that many more classes to get it.

So you can't say that in such generality

@heather Well, for example, math majors here often take honors classes, which are much faster and in-depth

What you want is differential geometry. GR doesn't care about statistics, or algebra, or number theory, for instance

I'm just wondering how I should prepare myself

@ACuriousMind Not even statistics?

So if you do math, and end up doing the latter, then you've gained nothing for understanding GR.

@SirCumference Well, I'm sure you'll find some specific setting in which statistics might come up, but I generally haven't seen much of the mathematical approach to statistics in physics

Hmm...would knowing more math help me in general be more employable as a physicist?

@ACuriousMind as I understand it, you get credits for classes. Majors, i.e., certifications that you know something about a subject, require that you have a certain number of credits from classes in that field. You can therefore get multiple majors by getting the required number of credits for each type. This is easier than you'd think, as many classes required for majors overlap - for example, a physics major may require some math classes, and so lead (after more math classes) to a math major.

That's why I say you shouldn't study "math" unless you have some independent interest in math that's separate from physics. Otherwise you'll learn a bunch of stuff that's actually useless for what you set out to learn

@heather The problem is that courses have varieties depending on your major. (e.g. Calc I could have a biological science version, an engineering/physical science version, a math-major version), each of which have different speeds and rigor

Naturally, the math-major versions (honors) are the most in-depth, most difficult and fastest

@SirCumference oh, that makes things more confusing. So you're saying it might be useful to double major so the math classes you're taking are more in-depth, especially (for you) the ones pertaining to GR?

@heather You can take any version of the class, but biology majors are encouraged to take the bio version, engineers and physics majors are encouraged to take the engineering/physical science version, and math majors are strongly encouraged to take the honors version

Is there even a single differential geometry class in these math classes you'd be taking?

@SirCumference Does one have to be a math major to take the honors versions?

hmm, okay.

So I could take the honors classes. But I feel like double majoring could help me get ahead in the field, since I'd have a Bachelor's in math, be encouraged to be more knowledgable, etc.

@HDE226868 Not really. They're not necessarily encouraged for most physics majors, but GR seems like a math beast

It's a specific kind of physics that requires a deep understanding of math, different from things like aerodynamics, etc.

@SirCumference On the level of rigor of typical physics, I don't think GR is particularly math heavy compared to the other theoretical subjects, really

I wonder what gave you that impression

Mainly the sneak-peaks and scratching the surface that I've done in my classes

Maybe I'm just worrying myself. But would there really be no advantage to taking as much math as possible, if I want to be a physicist?

@ACuriousMind "most of math"

@SirCumference Then I would not recommend taking all these other classes you may not want to take simply for the sake of one or two classes you'd like to.

ACM please tell how analysis is useless for GR

@0celo7 Analysis is not most of math

@ACuriousMind what is most of math

@SirCumference From statistics you need to know uniqueness theorems for measures and Tauberian theorems.

@SirCumference There's always an advantange in knowing more math! ;) But I think the advantage is not as straightforward as you might be imagining it.

Yeah, the other thing that might happen is, if the course goes too fast, I could come out with a worse understanding of the subject than if I had taken the physical science version

@0celo7 Pretty much anything except analysis and differential geometry, in this case :P In any case, quibbling about what math exactly you'd need here is kinda beside the point of this discussion...

Despite the honors version going in more depth

@SirCumference . . . As well as only getting emphasis on the pure math part of the subject, rather than its physical applications.

@HDE226868 That's true too...

I guess I just don't have the time to learn as much math as I wanted :/

@SirCumference Serious question, what math do you even need to learn for the GR you want?

@0celo7 Well, I want to be a cosmologist

So read the physics books on GR like Carroll.

Only insane people like math.GR.

But I could just take the classes and get credits...

@SirCumference In that case, you should probably talk to @Jim for advice best tailored to that goal

@ACuriousMind Good idea, thanks

The answer is likely that pure math classes are unhelpful.

@SirCumference This year, I decided to take the honors (read: more theoretical) versions of two math classes because I wanted to see if I liked them enough to consider a math double major (and I did). Some of my friends chose the regular version because they're not doing a math major; they're just doing some variant of physics and didn't care about the extra pure math components.

@HDE226868 Worthless information without knowing which class

Also how do you have time to take a random extra class

@0celo7 Not worthless, he has a point

@0celo7 Multivariable calc and linear algebra. Not very advanced stuff, but there were some clear curriculum differences.

@0celo7 ? I only took four classes each semester, one math class per semester.

What the hell

@HDE226868 If it focuses on the theoretical aspects, is it a good substitute for the physical science versions?

You're only doing 12 hours??

@0celo7 Uh, so did I?

18/19 or bust

I think if I did 18 in my school I would die.

Physics is our hardest major

@0celo7 . . . Plus weekly problem sessions, and labs, for physics. It came out to ~15.

I did 12 first semester, 15 second semester

@SirCumference shrug Depends on the course. It would be worth talking to the professor(s).

@ACuriousMind Oh, that ergodic theory/representation theory class got canceled :/

Got me acclimated

@HDE226868 Yeah, should've thought about that. Thanks :)

@SirCumference What GR did you try to read and what math were you missing?

@0celo7 I didn't get much further than the basics of the FLRW and Schwarzschild metrics

Also a derivation for the field equations, IIRC

That doesn't answer the question

What book?

I don't remember, it was a year ago

Eh, most of the time

you're a savage

what the hell

?

you're selling your children

Chill...

BTW, I still don't know what math I should take

have you taken calc 3?

Yeah

Gonna take diff equations

you don't need ODE for what you want.

Well, it's a requirement

I know, but you don't need it for basic GR
