Why do doctors have such shitty handwriting?
I have bad handwriting as well but I can instantly improve it if I know someone else is going to read it.
I honestly think they just don't give a shit.

I don't understand the difference between creating and reflecting limits in category theory as defined on p. 151 in Peter Smith's introductory textbook. Theorems 95 and 96 seem to confirm this but apparently creating is a stronger condition than reflecting. Please help me out
Why do you brainlets not even know how to ask stupid questions? At least post theorems 95 and 96, brainlet
>>9103701
Theorem 95. If the functor [math] F: \mathbf{C} \to \mathbf{D}[/math] creates limits of shape [math] \mathsf{J} [/math], it reflects them.
Theorem 96. Suppose [math] F: \mathbf{C} \to \mathbf{D}[/math] is a functor, that [math]\mathbf{D}[/math] has limits of shape [math]\mathsf{J}[/math] and [math]F[/math] creates such limits. Then [math]\mathbf{C}[/math] has limits of shape [math]\mathsf{J}[/math] anf [math]F[/math] preserves them.
Huh, while writing this I think I got it and I can't believe I missed it before.
Creation implies reflection and preservation, I guess.

I know the american university system is a scam but what the fuck do i do if i don't wanna become a plumber or an electrician?
>>9132134
You have three options
1) Get a free ride either because of previous academic achievement of because you are a minority
2) Kill yourself and pray that in your next life you are born rich and/or a minority
3) Suck it up and get loans but go to the cheapest university you can find (public obviously) and then through merit try to reach the stars.
be a mechanical engineer or electrical engineer
oh you said other than plumber or electrician
try physics dude there's a HUGE market for string theory

hvac guys are pretty cool
up coming math test and its really fucking hard, and if i fail ill probably kill my self. any advice /sci/?

Practice more. There's no math gene, people only get good by practising. Leave /sci/ right now, read about the things you don't fully understand, and then practice every relevant exercise you can get your hands on.
If you actually do this you'll do really well, but you're probably too lazy to bother, and you'd would rather cry on /sci/ about being a brainlet.
>>9131409

just do practice problems.
How do I fucking complete a square?
I search for it everywhere and there is everytime a different way to do it, I just get so confused when I see there is an easier method I then wonder why that other person did it by adding/substracting b/2a (b^2)/4a
So how do I fucking go on this shit?
What's the definitive method of completing a square.
Khan academy tells me to simply search for the b coefficient but it sounds retarded.
>>9130851
Consider that (a+b)^2 = a^2 + 2ab + b^2.
So if you have a quadratic expression in the form x^2 + 2bx + b^2, you know how to factor it easily. Now imagine you have a quadratic in the form x^2 + 2bx + c = 0. How can you get it into your factorable form? Simply subtract c from both sides, then add b^2 to both sides. That is, take half of the coefficient of x, square it, and add to both sides. Then you have (x+b)^2 = -c + b^2, so x + b = +- sqrt(b^2 - c).
>>9130868
Also, if the coefficient of x^2 isn't 1, then just divide through by that coefficient first.
ax^2+bx+c=0
x^2+(b/a)x=-(c/a)
x^2+(b/a)x+(b/2a)^2=(b/2a)^2-(c/a)
(x+(b/2a))^2=(b/2a)^2-(c/a)
Now you can find the zeros by taking the square root of both sides.
Is Saturnus real? Look at it. It looks so god damn weird. Look at that stupid ring. And that tilt. What does it think it is?? Why does it do that, what is its purpose??? I cant believe Saturnus is real. It seems like a satire from some space comedy.
The ring is temporary though, see it while it's still there.
If there's a conspiracy behind Saturn around this. I'll back it. I don't trust Saturn.
Saturn has a core, but it's not solid.
It is real
Saturn has no brain, it can't think
It has no purpose, it just exists.
These are all retarded questions, suck a fat one

A lot of people don't know that there are people that can't visualize images, but I only discovered last year, when my cousin showed me an article, that there's people that can actually visualize things.
In my case, it affects 4 of the 5 senses. Thankfully, I can listen voices in my head and talk to myself like a good autistic person.
ITT: tell your stories.
>>9130382
>visualize images
But images are already visual, no? They shouldn't require any specific effort to be visualized. In order to visualize visual stuff, you effectively should have no graphic memory. Strange how you can type if you don't know what letters look like.
>>9130382
This would explain why retards can't grasp basic geometry or linear algebra.
>>9130397
It means that you know how they are but cannot visualize them in your head, only when you are seeing them atm.
For example, I have a lot of trouble to explain a course from A to B that I already know from my memories, but when I'm going from A to B, when I arrive at intersection or things, I know where I have to go.
I read somewhere that this, maybe, was a problem from some specific neurons that retain the images, but don't allow to visualize them, like a connection problem.
