Long story short; I failed math since the 9th grade of high school because I didn't care. And my brain got even lazier since. But today I read something about algorithms and looked them up on wikipedia and somehow I got really REALLY interested.
So it's time for me to start over with math. Where do I go online? and what do I start with? I'm looking for sites, tutorials, anything really.
Where would YOU got to on the internet if you woke up with only your multiplication tables and a suddenly obsessive and unexplained desire to crush numbers?

it doesnt have to be like this. you CAN live a happy life without math if youd just give it a chance
I can't stress enough that I'm not trolling. It's 8:30 am here and I woke up with nothing else going on and bizarrely motivated. I'm just looking to learn.
I understand nothing about math and I do algorithm research for a living. You're gonna be alright.
What does /sci/ think of intuitionistic logic and mathematical constructivism?

I think it's a fucking pain in the ass because I'm stuck on the first problem of my metalogic homework. Proving shit within a language is just easy rubiks cube puzzle shit where you shuffle stuff around; anyone who's smart enough to do basic algebra can do that, but proving things about formal languages themselves is just fucking weird because I'm never sure if I'm essentially just begging the question. I don't get why I can just whip up a language to talk about the language I just whipped up, it feels like I'm just kicking the can down the road.

Why does /sci/ hate popsci? Whats wrong with educating the public about some of the more interesting aspects of science?
Pic related, its what got me interested in physics in the first place

there's popsci and there's popsci

>Why does /sci/ hate popsci?
I mean it's good for getting people into an extremely basic level of science. Beyond that it's just awful awful. Too much hand waving to be useful yadayada.
The general public is not gonna read a book on science and say, "Oh shit creationism IS retarded". Overall it's just useless circlejerking for comp sci undergrads who got a c in calc I cause they forgot the quotient rule on the final exam.

You don't know that. Theres a correlation between education and creationism.
What should I call my new math/science YouTube channel? It's mostly biology, chemistry, and physics. Pic unrelated. But please give me some good ideas.

Does anyone know a simple way to manipulate x(1-x) to get a double humped function such that f(x) still equals 0 at x=0 and x=1?
Basically the pic related except the zeroes should be at x=0,1 precisely

>Does anyone know a simple way to manipulate x(1-x) to get a double humped function such that f(x) still equals 0 at x=0 and x=1?
How about multiplying x(1-x) by a function that doesn't diverge at 0 or 1 or adding a function that also vanishes at 0 or 1?
[math] (c\,x^n)^2 \cdot \left( 1 - x^{2n} \right)^k [/math]
You are suggesting you want symmetry but havent explicitly said you want -1 as a root. It isnt going to work with something like x^m*(1-x)^n, because it will have terms with an odd power and so wont have symmetry. As long as you delete the +0.2 from the function in the picture it seems to have everything you want.
So i basically argue that a general human ethnicity has "evolved" further than any other (I suggest asians in general terms).
But by "more evolved" i merely suggest that a certain population is a product of a greater number and wider selection of generations, and as a result this population has experienced more genetic mutation than any other, which makes them "evolved" to a greater degree.
This makes sense doesn't it? Its like if you compare the offspring of two human generations spanning 100 years each from a pairing of first cousins, and the offspring of 4 human generations spanning 25 years each from pairings of those hardly related. The latter product would have had more evolution.
>>8704403
No, this is retarded. One member cannot have "more evolution" than another member of the same species.
>daily reminder that racism has ZERO biological basis
>>8704403
Evolution takes much much longer than a few generations to obtain any noticeable results. Furthermore not all mutations are improvements, the vast majority are detrimental to the organism. In a day and age where natural selection has been removed from human society, the only further evolutions will be on the basis of preference, not survival. So even if what you were saying was true, being more "evolved" today has less to do with being better at anything and, more to do with being too stupid to use birth control. We need to abolish government assistance programs, or at least vastly shorten the duration you are allowed to use them. Its cruel yes, but in the long run we are doing the species a huge disservice by keeping human parasites alive and reproducing.

Define "natural."
If chemistry is defined as the study of matter, then what is the study of antimatter? If it's not matter then it can't be chemistry, so what would the study be called?
antichemistry

Dopamine is a phenetylamine. Methamphetamine is a phenetylamine. Dopamine presses the fun button in your brain.

I just gave it a go and wow, when I thought I got it, it just straight up does something unexpected right afterwards. I guess I'm too much of a brainlet to fully comprehend the child prodigies who can think in a 4 dimensional way.

You can kind of develop /some/ thinking. Read the site, it gave me lots of insight. In and out are a whole new dimension.

Hey /sci/, I'm having some trouble understanding electric shock and how isolation transformers protect you from it. Can someone please explain. Here's what I do understand so far
In an undergrounded system, lets say connected to a metal toaster, if there's a faulty hot wire that connects to the metal frame, the will become charged and part of the system. So if you touch it, your body will become part of the circuit and the current will run through you causing an electric shock.
If the there's a ground wire attached to the metal frame and the hot wire has a defect connecting it to the metal frame, the electricity will run through it, to the neutral part of the system and trip the breaker turning off the power.
So I'm confused why an isolation transformer protects against shock. It's not connected to the ground. If a faulty wire touches a metal piece of equipment and I touch the equipment, wouldn't I get a shock just like in an undergrounded system?
Please help.

I don't even know how to converse with math majors. When I find out someone's a math major, I literally freeze to find a topic to share with that person but cannot think of any so I just end up not associating with that person
