I only read the textbooks for my humanities classes

For science/math i just do the questions at the end of the textbook. Screw all that unnecessary reading.

>>8637370
i typically only read math and physics books. most of the engineering books were dogshit so i didn't bother.

>humanities class
>history of law

>there are two main philosophies of law but some other important philosophies of law to consider are Eco-Feminist and Critical Theory of Justice

i cant make this fucking shit up

It is.

No, the brain is very inefficient and contain a lot of "junk" code that would not be useful in a human-level intelligent system. Furthermore, the underlying hardware is very different. It's not far-fetched to expect the best algorithm for a strong AI may not be anything like what's happening inside the brain at all.

> the analysis of evolutionary brain procedures to build efficient programs.
The more generic you are the less efficient you beomce. Human cognition is also riddle with shortcuts. Statistically efficient at certain common human task, and statistically very inefficient at everything else.

This is what happens when you let your space program become a pork program. You do stuff that doesn't make sense, and people die for nothing, their lives thrown into the same hole with billions of tax dollars and thousands of American lifetimes of effort.

It depends on how complex the brain is.
can it pass the mirror test?
will it show reflective behaviour?

just human cells is not enough, see how liberals kill babies without care.

the slope is given by the tangent of the angle the line makes with the vertical. you can calculate it by the change in y coordinates divided by the difference in x coordinates.

>it's better to continue having sick babuies with low quality sperm than to become voluntarily infertile.

Not sure that's true when dealing with societies of people that experience kin selection.

>>8637083
The argument of the selfish gene hypothesis is that human societies are NEVER kin selected. We are only kin selected insofar as it benefits the transmission of our own genes. If, as a result of my own poor quality sperm, I can no longer get an erection, and my younger brother has twice the children I have, then you have an argument. But that simply isnt the case; me continuing to have children has no effect on my younger male relatives fertility, males are typically the sole provider of a stone age family.

At any rate, even if it were true, wouldn't evolution select for males who could retain high quality sperm into old age?

Another point, why then do we see psychological impotence? One's mental health would have nothing to do with his sperm quality.

>>8637095
>me continuing to have children has no effect on my younger male relatives fertility

You clearly aren't thinking about this in an unbiased fashion. The answer is obvious...

The answer is you producing low quality children will divert resources away from your brother's healthy children. By and large human reproduction has not been limited by fertility, but by resources available to sustain someone to adulthood.

If you having and caring for 3 children who are sickly and need lots of resources, it could cause your relatives children to starve. Resource scarcity exists and additional males in a given space don't get the same marginal gain in resources collected.

>males who could retain high quality sperm into old age

Well, relatively we can. Men can reproduce successfully into their 60's. Contrast that with women.

>Psychological impotence

Probably really complex. My guess is having to do with social hierarchy and selecting so the most alpha has the best chance of breeding. Essentially a male being put into a situation that is extremely demeaning shuts off their capacity to breed because they don't possess qualities conducive to being at the top of the social ladder.

A thought I've had along these lines is why we are aroused when we see other people mating (monkeys for example masturbate while watching the alpha mate with a female), is again kin selection. They're similar enough in genetic profile that it still takes an effect, even if they aren't direct brothers or nuclear family, being part of the same tribe generally guarantees you are closely related (The extreme version of this effect being the basis of how ant colonies and bee hives work.)

So you're 24 human years and 18 demented years in autistic? Aren't you just a late bloomer?

>downs tongue

I have no idea what I am reading here. Clearly the derivative does not exist.

>>8636849
the weak derivative exists, and is equal to 5*delta(x-1)

>>8636852
Is there a proof of this basic property? The delta(x-1) makes sense to me, but it's not clear why the coefficient is five and not just one.

No. I can find 2 white circles on top of a black triangle on top of a white square.
Are you delusional?

2 circles times 3 points gives you one 6 ......

>>8636689
the three angles in an equilateral triangle start with 6

Is there a limit to how big your mom can be?

>>8636682
There is likely one star that is biggest, but there is no reason to think a star (lit or dark) need be limited by size/mass. The theoretical original singularity was an infinitely compact sun, so it was likely the biggest, and still is.

>>8636682
>Is there a limit to how big a star can be?

Yes, between 150 and 200 times the size of our sun.
>Is there a limit to how big a black hole can be?

No.
