I never don't study.
Every breath is an opportunity to pick up new data and formulate new ideas.

Keep up the good work Jamal.

I got told that 60 hours a week including lectures is a good time. So if you have 40 hours of lectures you study 20 hours.

Just watch a jack video.

It was already proven to be possible in real world too.

It's not about belief. It's just a certain axiomatic system yielding certain theoretical results. There's nothing to "believe" in.
Don't get your panties in a bunch. Math doesn't have to be "real" to be insightful.

>>9130031
I've read some articles about possible applications, but I'm not too convinced. I actually like the idea that it's just a theoretical result.
If you care to share a more concrete application of the theorem I don't know about (I'm no expert) I'd be happy to hear.

The ultimate proof that the continuum is a lie and calculus is a sham.

Its not worth the burnout effect.

Massively overestimated. Only occurs with extremely neurotoxic variants like Methamphetamine or abuse.

Maybe this would be an argument if people lived much longer, but given the massive boost it can give you early in life (which is the absolute most critical time), it's objectively better to use it early and if needed deal with the acute withdrawal later.

There isn't even scientific evidence of long-term changes.

No but they count as being a fucking junkie loser who has to manipulate the chemistry of their mind to be useful

Assume r = 2
A = 2+2 = 4

Higher resistance requires more power.

There is no point in asking here.
You could find the same information on a book.
You should really try and prove it yourself.

>>9129960
[math] \frac{1}{a_n} - \frac{1}{a} = \frac{a - a_n}{a a_n} [/math]

Given that [math] a_n [/math] converges then you can find some k such that [math] k < |a a_n| [/math] and then [math] |\frac{a - a_n}{a a_n}| < |\frac{a - a_n}{k}| = \frac{1}{|k|}|a-a_n| [/math]

and you know that goes to zero.

>>9129962
No, it's not in the book.

And trust me, I tried.

>A general theory of duality for locally convex spaces had to be worked out: Schwartz and I [Dieudonné] had started its study for Fréchet spaces and their direct limits, but we had met a series of problems we could not solve. We therefore proposed them to Grothendieck, and the result turned out to exceed our most sanguine expectations.

>In less than a year, he had solved all our problems by very ingenious new constructions; then, with the techniques he had developed, he started to work on many other questions in functional analysis.

Who's that dumbfuck?

Fermat

In addition, it can also be proven theoretically that evolution would happen to ANY kind of living system. So it doesn't matter if aliens are made of carbon, hydrogen, oxygen, and nitrogen. They can be made of metal and live in 800 K and still experience evolution. No organism in any kind of environment can escape evolution.

And I needed zero (0) empirical evidence to ascertain the truthhood of that theorem.

>>9129670
>How does that insight make you feel?
Really good because that proves biology is a subset of math and therefore I am smarter than anyone that is not a mathematician.

Feels good man.

evolution isn't just the tautology that what survives survives
it's the theory that selection and mutation can explain the genesis of all living organisms from a common ancestor over millions of years. if what survives survives, why isn't there just a single life form? why is there such differentiation among creatures? or why so little? where did this and that organ come from and why?
the "proof" of the theory is its ability to explain all of these phenomena supported by evidence.
what survives survives, but how do we know all life wasn't placed here in pre-differentiated forms by a martian zookeeper? because of the positive claims supported by contingent evidence that the theory makes beyond simply what survives survives.
there. I just improved your thinking in one short post. you're welcome.

Black people have the most diverse phenotypes of any skin colour, so your sample is even less representative than it might seem.

Thy don't have opportunities to become wealthy in their homeland, this is coupled with governments that turn a blind eye to crime. Since there is no extradition treaties with these former soviet bloc nations, it becomes a mecca for computer fraud. They are not so much better then the rest of the world at hacking, rather their computer gurus turn to hacking for their livelihoods because there aren't any legit options.

The author makes a good point that math education is shit but the problem is that it is shit because the average person is shit. I doubt anyone except those already predisposed to doing mathematics would give two shits about the derivation of concepts and the intuition behind them. And I do not say this because I am some elitist who thinks others are too retarded to understand what I do. Instead I say so because I can see my own reflection.

Maybe when it came to math I cared about the history and the derivation, intuition and rigor behind concepts. But I also had to take history, geography, english, spanish, literature, music, art, etc. And I did not give a single shit about those classes. And had the fucking teachers forced us to see the intuition and development behind certain art styles or behind certain literary work then I would have gone fucking mental. Give me my literature worksheet, thank you very much. Oh, what are the questions? What is the name of the author, the novel and find the literary context of the novel? Thank you! Let me just copy off wikipedia and hand it to you because I do not give two shits about literature. If I could turn in my own ass wipe as literature homework I would have done it.

And I am being hyperbolic here but I can understand that the way I feel about literature, most people feel about math. So don't change the system. People who hate "worksheet math" will hate real math even more.

>>9129628
Oh come on, are you guys really so blind. We all know the real reason math classes are required for non-stem majors in high-school and in college is to give teachers employment. The reason why math teachers are against maths becoming optional is because most people wouldn't take maths class since it's boring to most of the public. Math teachers would lose their jobs.

Please don't fall for the well-rounded educational person argument. If a person isn't going to use it in real life, there is no point in learning it. Afterall, nobody would agree that a English teacher must learn Chinese in order to be well-versed person so therefore they can teach English class. Who cares if they know Chinese or not?

yes but more generally whether it's worthwhile to prop up coal power

Depends on the specialization. Webdev is currently being fucked by automation, as will other specializations, although much slower than most other kinds of jobs. Pure CS is safe pretty much forever though

>Why is it that the Order of Operations is what it is?
Because it's convenient.

>And How would the entirity of Mathematics be different if the order was different?
Not at all.

Order of operations is a notational convenience, not a piece of mathematics as such. It is an agreement on how we write certain mathematical things on paper, nothing more. If we were to switch to different conventions here, the way we put ink on paper to describe math would change, like writing it in a foreign language; but the underlying math would not change one bit.

>Is there a logical reason why the order is, the way it is? What is the logic behind the way it is now?
The logic is that this particular notation leads to the simplest and shortest writing for the mathematical things we want to write down often.

>So what would things look like if the order was agreed upon to be like... PDMSAE ?
We would write a bunch more parentheses when doing math, making everything harder to read and easier to misunderstand.

>doesn't that make it completely "made up"? And just artifical?
The *notation* is made up and artificial. The *concepts* we describe using this notation is natural, and would not change if we were to change notations.
