The human brain reaches peak performance at a very young age. As example, if you look at Go or esports, the best are usually between the age of 16 and 25. And both but especially Go are experience based so when a 16 year old beats the 30 year old former world champion who dominated for a decade then maybe peak performance is between the age 16-20 even.
As intelligence is by far the strongest predictor of overall success in life, slowing down the decay of your intelligence is very important.
So how do you prevent your brain from deteriorating?
>>9159875
I myself assume that staying fit both mentally and physically as well as having a good diet are essential basics.
Furthermore, nootropics could help.
Specifically, SSRIs increase neuro and synaptogenesis and by undoing damage to the brain they could potentially help you maintain your intelligence to a higher age.
Of course there are many other factors. What do you people think?
>>9159875
I don't think you can. its a natural developmental process.
>>9159881
The problem in this area of science is that there is evidence that drugs have a positive neurobiological effect but this is rarely if ever demonstrated on neuropsychological tests. Theres little or no evidence that SSRIs or other nootropics have a significant and substantial long term effect on cognition. When they do have an effect, they tend to be on people who are on the lower end scale or have significant disability in that area.

>As intelligence is by far the strongest predictor of overall success in life, slowing down the decay of your intelligence is very important.
This actually wrong. The biggest predictor of success is how much money your parents have. Some smart kids get full ride to university but the become 6 figures nobodies, meanwhile all rich kids end as at least millionaires, sometimes billionaires is they are able to inherit all the wealth from their dad.
I think partical cannons can be achieved by having a particle accelerator inside the cannon and using protons or electrons as ammo which produces a very large amount of energy. Just need too find out how too control the energy current to a specific directions without losing energy
Might be a powerful weapon for inducing skin cancer OP.
Electron litography is already a thing you know? Thats how transistors are made, electrons destroy the micrometer-thick photolayers and structure your wafer.
I think we would be much better off developing high pulsed laser guns, or rail guns if we had better energy storage.
Charged particles repel each other, brainlet
We have had particle cannons for several hundred years now, OP. A medieval cannon is a particle cannon accelerating large iron particles.
>A monad is a monoid in the category of endofunctors
Im not understanding this, as I understood it, its not.
a monoid is an object [math]X[/math] with 2 arrows [math]e: 1 \to X[/math] and [math]m: X \times X \to X[/math], where [math]X \times X[/math] is the product. The product of [math]T[/math]in the category of functors is [math]T \times T[/math] such that [math](T \times T)(X) = T(X) \times T(X)[/math], but for a monad the arrow is from [math]m: T(T(X)) \to T(X)[/math]. The only way this can make sense is if [math]T(X) \times T(X) = T(T(X))[/math] for all X. Is that true, or do I have an error somewhere? Or are they talking about 2 different products when they call the first one a product in the category of functors?
>>9159689
How come four arrows in a square is math but one arrow pointing from A to B isn't?
>2occatl net /CG/ CG.pdf
>>9159689
after some thought, I think I get it now, we can define a functor [math]\circ: T \times T \to T[/math] as [math]\circ: T \times T \to T\circ T[/math], then the multiplication for a monoid [math] m [/math] is related to the multiplication for a monad [math] \mu [/math] by [math]m_T = \mu(\circ(T\times T))[/math]
Nah dude it's a burrito!

How is government funded science and research responsible for so many innovations compared to private businesses?
>internet, world wide web, transistor, microchip nuclear energy, atomic bombs, rockets that landed on the moon, CERN, GPS, etc.
>railguns and fusion power might be up next
By this point, you'd expect the efficient free market enterprise to invent dyson spheres, or teleportation. Instead, we get iphone 8.
They'll throw infinite amounts of money at anything that might have military value.
The government just hires a lot of scientists and engineers. There are plenty of private sector discoveries, but it's no surprise that there are so many government-funded ones when they fund like 1/3rd of the research that is done. It builds the economy and helps maintains our state's global position both militarily and socially; it's a no-brainer.
Businesses are risk averse. Shareholders could give a fuck about anything other than profits

Hey sci
I'm really curious about some of the algebra behind ODE's and other seemingly-separate areas of math. For example, I always thought it was kind of arbitrary that, for an n-th order linear homogeneous ODE, the solution space is generated a linear combination of n linearly independent functions.
I'm not much of an algebraist, or whatever the proper term is, but I'd like to start looking into that side of things. I've only read the first few chapters of Artin -- would that text elaborate on some of these issues? Would Pinter suffice? I'm looking for something I could hopefully get through somewhat quickly, if possible.
Thanks in advance
Samefag, I'd also like to know why we are able to assume
u_1'(x)*y_1(x) + u_2'(x)*y_2(x) = 0 in the parameter variation algorithm.
Anybody???

Is natural/organic shampoo actually better to use, or is it just a meme? Are there any benefits?
>artificial as an ominous adjective
all the stuff to the left also has chemical names you know
Idk but I heard selenium prevents dandruff and I doubt organic shampoo has that
Bald people dont have to worry about this.
Hello, I have a request (I'm also going to put this on the request board too) is there any market place online where I can buy ephedrine/pseudoephedrine.
Sorry if I wasted your time.
Idk where you might, but it might help to google ma huang and try going for the chinese plant version instead. ephedrine/psuedoephedrine is purified from ma huang so it's effectively the same
Mr. White you need to find your own supply.

What is /sci/'s opinion on economics?
Pseudoscience on the level of astrology.
its modern form makes many assumptions about human nature, and in general requires one to make some assumptions about human nature.
The best and most rigorous social science by a large margin
What does /sci/ think of this textbook? Any better recommendations?

Not a bad book but if you're smart you could just read Spivak or Apostol instead to save time
What's the difference in early transcendentals and the standard calculus book by Stewart?
For an engineer, or just general STEM person who needs math, Stewart is hard to beat to be honest.
For a math major, Spivak, Apostol or Thomas

one or two more generations. thats all we need to remove the filth

i don't talk about this stupid black vs. white bullshit. i mean all races.
