alice took a boatload of acid, i wouldn't think too hard about what she says she saw

This isn't an /x/ thread, friend.

First of all, humans don't depend on individuals producing tons of offspring. Our evolution takes place at the societal level now, we're not rabbits. But that's probably not why. It's probably just because of the proximity between the ass and genitals where there are lots of nerve endings.

>>9147918
>It sure doesn't help our species to reproduce
not every feature that a species evolves has to be for the sole purpose of boosting reproductive fitness.
and no scientist ever said anything of the sort.

so why are you implying that it has to be the case?

>>9147918
>god created us in his own image
>humans like dicks up the ass

what does this mean?

>>9147590
>yet you still have a relatively low IQ
Speak for yourself.

>>9147599
Can you instantly solve complex math problems that are typically left for computers? That is what I meant by relatively. The processing power of the brain vs what people demonstrate it can do is pretty sad. You can say it is because we did not evolve to do it but technically we should be able to anything a computer can do, only better.

>>9147590
Your delivery was offensive and it hurt my feelings. Try again

You mean this?:
[math]
1000 \cdot 1.05^{25} + 1000\cdot 1.05^{24} + ... + 1000 \cdot 1.05 \\
= 1000 \cdot \sum_{k=1}^{25}1.05^k \\
= 1000 \cdot \left(\frac{1.05^{26}-1}{1.05-1} - 1 \right)
[/math]

>>9147858
Sum from k=1 to k=25 of q^k is (q^26-q)/(q-1), not (q^26-1)/(q-1)

>>9147865
nvm I was trolling

>>9147578

It's not a puzzle, just expand the equation.

>>9147598
I'm a mathlet, I don't exactly know what N(s) and D(s) are...

I assume T(s) represents the transfer function (expected H(s)).

Any hints?
I should be able to take it from there.

>>9147612
look up laplace transform

It's too late for you now. You must deal with the ramifications of your actions.

consider yourself damned lucky.

Can you be more specific? Can you cite some papers or scientific articles that compelled you to distrust the scientific consensus?

>>9147441

The worst part of the post is the phrase "to me", which connotes the creation of one's own truth. The point of science is that it demonstrates certain categories of observable and (nominally) objective Truth which exist independently of subjective experience, and which consequently and happily do not brook contest once perceived aright, viz:

"To me, 2+2 = 5."

>>9147441
>to me
Nice opinion, please show me your academic credentials as a scientist, unless you want me to print your post and wipe my ass with it.

>>9147424
Ha, no. And you won't be one anyway.

>>9147428
what gives me away?

I don't know, do your Physics teachers look excited? Because that is your future.

1kg of gray. Next question.

>>9147384
Wouldn't that be 2kg of gray

>>9147384
Really? I would have thought 2kg of gray. Physics is scary.

>tfw no one responds to my shit thread

JESUS if only there was a way people could review something after they purchased it so they could express disappointment or praise.
You could also just dive right in and find out, then if it's too complicated find a more basic book, and when you finish that read this one.
You could also preview it on google.

Hopefully learning about the logic of life will help you figure stuff out like this on your own.

>What are irrational numbers.
real numbers that aren't rational

>What does it mean when the decimal part of a number goes on forever (repeating or not)?
what exactly do you mean? all numbers can be written this way

Irrational numbers are numbers that can't be formed as a ratio of whole numbers. That's about the beginning and the end of it. Ancient Greeks formed a mathematics of geometry and ratios (not yet working with purely abstract numbers, i.e. they'd never just say "3", they'd say "a length three times of another length"). They quickly discovered that lengths existed that can't be interpreted as a ratio of another length. In particular a right triangle of two equal lengths will have a third side who cannot be interpreted as a ratio of any equal subdivision of the two equal-length sides. In other words sqrt(2) is irrational.

Most likely, female.

The problem is we all haven't got much time as it is and I personally don't find it that appealing to make a whole youtube channel for just select few individuals. I think there's alredy plenty of the necessary parts on the YT.

>>9147178
To add to that

Anyone who actually got through these advanced topics couldn't probably see themselves covering the topic without necessary rigour and that pretty much means creating a whole set of rigorous lectures. That's a lot of work

but did gravity exist before the universe existed?
