Dont even know what youre referring to hilbert space but answer should be simple in my logic, since all the math in n-1 dimensions is possible in n dimensions, all math for 2d and 3d are valid in n dimensions
Think about this, you can do every geometry of 2d in a 3d space but cannot do the inverse

A lot of finite dimensional linear algebra breaks down in infinite dimensions, even in Hilbert spaces. I don't know where you get that from

The body can more readily divert resources to healing than it can while awake and active.

>Why doesn't the body just do this while being awake? It would be an evolutionary advantage because your chances of being killed by a predator are higher while you are sleeping.

the trait youre looking for isnt sleeping, but having the sense to dig in somewhere safe to sleep. Creatures that lack the ability to develop that idea would die out pretty quickly.

also id imagine never sleeping and being in a constant state of metabolic overdrive to repair oneself is far too taxing on the body to be a viable evolutionary trait.

I wish I could sleep forever, but people tell me that's called "suicide" and it's supposed to be something bad I guess?

sounds bretty good to me

>The body can more readily divert resources to healing than it can while awake and active.
Well, why? Is it because while awake it needs more resources/energy for body/muscle movements?
Then why don't we just get more hungry the more active we are?
Why does lack of sleep instead result in the effects shown in the OP image?

why does /sci/ make so many memes relative to its size?

>>8560945
It's not a /sci/ made meme just because it's posted on /sci/.

>>8560949
didn't the brainiac wojak meme originate from /sci/ and spread to other boards afterwards?

>learning about the quadratic formula in college

wat

also who would pay good money to learn how to do their taxes? pick up a fucking book or use google or something

>>8550658
>Quadratic formula
>College

American "education" at work everyone

>>8550658
Why do people perpetuate this meme? If you want to learn how to do taxes or have a good marriage, pick up a fucking book or use google, like the other anon said. And the quadratic formula should be common fucking knowledge. Why are people so stupid?

Dis gun b gud

Prove your case mathematically first.

We are already traveling faster than the speed of light.

to clarify, im talking about where the state of a system is fully reversed while conserving energy and momentum.

Why is that bullet still in the casing?

Consider a system of n particles and m positions for them to occupy.

There's n^m possible combinations.

Now consider that a system is in a certain state and then changes to a different one. The chance for the process to be reversed from position 2 to 1 is extremely unlikely to haopen randomly.

Time is a measurement in the change of states.

If a state of a system never changed, thered be no way of knowing if something "happened".
We only perceive time because we know things do change states and they don't reverse.

I've always found it interesting why constants are the way they are, gravitational, etc etc and why some forces like electromagnetic are so much stronger than gravitational, so if there were multiple universes that would be cool to know how forces and other constants vary

>implying that -1 and -13 arent rational whole numbers

Yes. It feels different. Have people told you they don't feel like it?

That's because they tend to avoid self-analysis. And I bet some actually noticed, but are self-conscious about looking weird and they decide to not telling you or saying "no".

>>8564179
How come it feels so different though?
Is it just how our perception works?
I remember a long time ago my best friend telling me about how we draw a mental map when we enter a new area for the first time. Does that have anything to do with it too?

Why is this simple thing interesting again?

I thought engineers had the lowest GPAs on average.

>>8562394
OP is talking about the highschool grades required to get into an engineering program.

>>8562383
It's a supply and demand thing. Engineering programs accept a limited number of students and lots of people want to be engineers so the entrance requirements are driven up. For a university to give engineering degrees it needs approval from the society of professional engineers so they can't easily scale up the number of students they accept to meet demand.

Consider not giving up after an hour

Consider some problems have nontrivial and inelegant solutions and an author may resort to esoteric techniques to avoid subscription to a 2 page contradicting construction.

Consider killing yourself.

The most cited papers in a field aren't typically what's covered in a bachelor's degree.

>>8560732
>>8560742

part of CLRS is typically covered in an intro algorithms class.

it's because nobody knows what computer science is

the people who are super psyched about going into computer science and becoming professional javascript programmers have no clue what computer science is; they think it's just how to program or some shit

universities DO know what it is, but they adjusted their curriculum to cater to the less inclined crowd (aka javascript monkeys), and pass off programming 101 as "computer science"
many of the javascript monkeys drop out because computer science isn't the art class they thought it would be

because of the above, those who don't know what computer science is get a bad impression because there's so many object oriented social justice losers on the surface and it makes the whole field look bad

and it's obvious that the most cited papers are going to be actual computer science papers - nobody is going to cite java for dummies

that would be right if you had to ring all 5 regardless of whether you hit the wrong bell. If you hit the scroll bell when you don't mean to, then it resets the sequence
