Let n be a positive integer.
Assume n can be written as a sum of 4 triangular numbers.
By a theorem of Gauss, this is a contradiction.
Therefore every positive integer is a sum of at most 3 triangular numbers.
This completes the proof.

Medians and averages are for brainlet faggots, get the fucking age distribution instead: https://www.cdc.gov/nchs/nvss/vsrr/covid_weekly/index.htm

>why are boy more likely to be interested in things
>why are women more likely to be interested in people

>>11976734
Because it can't be diagnosed in females as easily leading to under-diagnosis since society treats women paternalistically. In women autism is not a drawback because it makes it so that they're perceived as extra cute instead of extra creepy.

no lol

actually it has some health benefits but not smoking it

no but nicotine can have some uses

>>11976699
Tobacco smoke makes me feel so good that it's not even funny. I'm not even a smoker but I still love it.

>>11976699
It obviously makes you hang out with the cool kids and shit on the nerds

I'm struggling with this as well. I think there's such a thing as practical mathematics motivated by financial gain, and that motivated by curiosity.

I'm more naturally motivated by curiosity, which is as much as a luxury as it is a valuable asset.

[math]
S=1+2+ \cdots +n \\
S=n+(n-1)+ \cdots +1 \\
2S=1+n+2+(n-1)+ \cdots n+1=n(n+1) \\
S=\frac{n}{2}(n+1)
[/math]

[math]
S=1+2+ \cdots +n \\
S=n+(n-1)+ \cdots +1 \\
2S=1+n+2+(n-1)+ \cdots +n+1=n(n+1) \\
S=\frac{n}{2}(n+1)
[/math]

sum 1 to a where a is even : (a-0)+1 + (a-1)+2 + ... + ((a/2)+(a/2+1)) = (a/2)*(a/2+1)
sum 1 to 100 : 100+1 + 101+2... + 50+51 = 101*50 = 5050

>>11976710
not (a/2)*(a/2+1) but (a+1)*(a/2) fuck

>>11976718
great, now prove that every positive integer is the sum of at most 3 triangular numbers (proven by gauss :) don't cheat :)

Science "says" there is no such thing as gender and no such thing as IQ.
Social """"Science"""" is not science

Are you still butthurt that someone disagreed with you on twitter?

>>11976586
wtf PDEs are far easier than Algebraic Topology. Engicucks are capable of grasping them for goodness' sake.

>>11976656
O yeah? Solve a pde analytically that's not the wave or heat equation.

>>11976658
:/

>>11976661
That's what I thought

>>11976658
how often are PDEs used in higher dimensional studies (string theory)

creative activity, like drawing or composing

Live a fulfilling routine that doesn't rely on whims or chemicals. If you are really in the gutter mentally then start with doing your laundry or something.

smoke weed jerk off and play vidya

Trust me, I am an expert.

>>11976537
Going for a jog every now and them might help. Physical activity is vital to sustained happiness. Sitting in your room all day like a lazy slob is going to make you depressed.

>>11976578
this is true, plus sports can be fun.

if you want the weed/jerkoff/vidya combo to hit extra hard working out does help.

>>11976526
So you slept on your face and arm and woke up with them feeling numb... hmmmmmmmmm

>>11976526
You should definitely ask a Cantonese knitting board instead of a doctor, you're off to a good start.

You're already brain damaged.

By definition, IQ is a measure of how intelligent a person is based on what the society sees as useful. So my opinion is that they get to live better lives in a society as long as they keep doing them favors. Society keeps them alive, and high IQs get to keep the society alive. Anyway that's just my opinion.

it's a meme, it's on yotube and wikipedia. Both unreliable sources.

That's funny I was doing that in my engineering bachelors, I thought physics was superior to engineering?

>>11976516
To apply control you need to be an engineer, chemical, mechanical, electrical or aeronautical, anything else is a poor imitation of the subject, you'll probably learn some undergraduate level shit and not understand the subject at all.

>>11976620
The classes I plan to take are offered by the engineering department. There's nothing similar to control in the physics curriculum.

Made me question whether control is something that is applicable in the realm of physics. On the other hand, I can only find stuff written by those two authors >>11976421

>>11976421
So some physical questions are questions of stability, I believe turbulence is one. So if you like fluids there's probably some physics there to discover because we know so little about turbulence. Aeroelastic flutter is another example of a stability problem the structures engineers do when designing a plane. For complicated structures there's definitely more physics to discover in that field. I once knew a guy who did his phd thesis on quantum control, I guess it's a thing.
