I used to study psychology for a few semesters and in one of the courses I learned that human races aren't actually races in the biological sense because eg. two blacks can genetically differ more from each other than a black and a white/asian/hispanic, while two german shepherds will genetically always be closer to each other than a german shepherd and a dalmatian.

are there any biologists here who can confirm this?

I know I'ts just a very superficial way to look at people's genetics but purely visually it seems impossible to me that nelson mandela might be closer to taylor swift than michael jordan genetically

not really, no, you didn't ask anything about biology, you asked something political at best. you care about science only as much as you can use it for retarded political questions, so no, wrong board

I stopped caring about math when I was introduced to the concept of negative numbers. What a crock of shit. If your equation can only be solved by inventing numbers that can't exist, like some kind of math deity , then you are fucking wrong and the math is flawed. Same for algebra solutions that basically say "the correct answer is whatever the correct answer is". Thats what the math said transcribed to words but god forbid if i wrote in down in english instead of the ancient math runes the teacher word mark me wrong.

Math is logical and numbers never lie my ass. Math is just as flawed as any other human construct.

He's a creationist meaning he believes evolution was just an algorithm developed by God he doesn't outright believe man magically appeared 10,000 years ago.

If he wants to prove P=NP then sure go at it, Knuth who is also religious believes P=NP and will be discovered eventually, all religious mathematicians do for some reason.

Nonsense.
You're confusing probability with probability density.

there are infinite events so if their probability is finite their sum is not one, and if they are 0 then their sum is 0

/sci/, let's calculate this : 1^x + 2^x + 3^x + 4^x + ... + n^x
all we need to do is express it as a simple formula.
PS : making it as a sequel of exponential numbers doesn't help, but an interesting approach would be to integer it among Relatives number

Yeah a good pre-calc sequence will expose you to the functions, identities, equations etc. OP has nothing to worry about as long as he does his homework

We are a collective of like minded individuals dedicated to publicizing scientific discoveries which have been silenced or otherwise stolen by public or private agents. We do not support the release of technologies which are legally owned and controlled by any group. Rather, we toil day and night to shed light on that scientific knowledge which is being illegally hidden to exploit an unassuming public. We subscribe to no political affiliations, only the self evident rights of man, paramount of which is his right to the general knowledge of his existence and place in the universe.

Holy shit /sci/, you've just been teleported back to 15th century central Europe.

What do you do to advance science and mathematics ahead of schedule, and how?

Let's assume you speak the language, and there are no time paradoxes involved.

renewable energy alternatives
all other answers are wrong

>>8589383
no such thing.

its a created fear of scarcity because it has the word "fossil" fuel. Oil comes from a layer of soil known to contain fossils, or so they say.
>>
>>8589383
Gradually transition to a combination of renewables and nuclear to provide clean and consistant energy

Still mine for natural gas and oil though, we need that for plastics and chemicals.

Does the educational system suck at selling math, or is math just inherently disliked?
22 posts and 3 images submitted.
>>
all math can be one by knowing how to input it into a calculator.

the educational system in America is purely business and not for the welfare. thus the difference between a "private" school and a "public" school.
>>
sucks at selling it. hard.

it's not the fault of the educational system though, it's the goddamn students. A lot of teachers come into the classroom with really high hopes and dreams. I guess they watch too many culturally binding movies about some white woman fixing inner city thug life teens with choreographed dance and get crushed when they realize 99% of the students really just don't give a shiiitttt about anything other than what's playing on their iPod and what Janet Roscro stuck into Timmy Turner at the homecoming dance.

Unlike a lot of subjects, math can't always be learned. It has to be practiced, understood. How well you can do math is very much tied to your intelligence. Teaching math is about the teaching of concepts, not just the teaching of information.

This is the reason why philosophy requires that you be intelligent, and why it is up there with math and physics in pic related. philosophy isn't just information, it's also concepts and ideas. Your performance hinges on your understanding, not just your knowledge.
