What happens if I give it a program that may or may not terminate?

For example, if I tell it to search for a contradiction to Goldbach's conjecture and one doesn't exist, can I interpret god-computer crashing as a proof of the conjecture?

>Specifying infinite speed without infinite storage and infinite precision

Pleb detected. Take this kind of crap to /g/.

>>7786881
bruteforce solutions to NP-complete or generally large problems all around.

probably decrypting bank info first and taking a dollar out of every account or something like that.

then bruteforcing open conjectures in math

When you shiver your muscles are creating friction against each other. This is what creates heat. Hyperthermia is when your body is too hot, so you muscles creating more heat would be a bad thing.

>>7793544
ok comrad dodge

>>7793532
Tremors/seizures can take place in certain cases. Is that what you mean? "Shivering" is a response to lack of heat in body. "shivering" during hyperthermia may be something that is superficially similar but not related to true shivering?

>>7792515
No, faggot. Spending 16 hours a day on 4chan is what's fucking up your vision.

Dumbass.

Was your monitor a CRT or an LCD? I think LCDs screw less with vision than CRTs from what I've heard.

Hm.

The last dollar was added for no reason to get 99, when it should have been subtracted to get 97, the actual cost of the shirt that you now owe 97 dollars for buying.

>>7789500

>You start with $0
You get $100 but owe $100
You spend $97
You now have $3 but owe $100
You give $2
You now have $1 but owe $98
which in total makes your net worth -$97 + $97 shirt = $0

You actually owe each mom and dad $49.5 (half of the $99. Grab some poker chips or coins and try it.
Math is more about visualization than memorization. If you have no imagination, you'll never do well in Math.

>>7793504
Why would you need to explicitly compute integrals at all? Integrals are only useful to prove some theorems in cohomology, and there you don't compute them but only show their existence.

In many practical situations it suffices to have numerical estimates, but goddamnit if you learned how differentiation works you can damn well learn how to do it backward. Furthermore numerical estimates don't give you neat formulas when those are available, but the pen and paper way does.

Why everything other than math seems like politicized garbage that is merely rehearsed as anecdotal truth. Yet, that's what comes about when the public is nurse on science fictions and news stories about what's going on over in Endor. Math is the only place where a person can explore the philosophy of thought and apply it to the substance. People should look at scientist and media outlet as liars, not peddlers of truth.

"We hold these truths to be self-evident."

Lay the foundation of knowledge on the bedrock.

Why would you read this outdated crap instead of a modern biology textbook?

i've read a few pages of it. the way it's written is pretty intense from what i remember. his topographical aspect was more akin to how migration was favorable for the species in a given context, although his understanding what was favorable could be questioned.

Yes, you are a retard.

Why wouldn't you read something like The Origin of Species, its influence is spread throughout the 20th century.

Pretty sure there are robotics jobs in the private sector but its mostly menial wageslave work.

You'll probably work in either maintenance, debugging, software dev, or just button-pushing in a factory that uses robots to do all the work.

But if you want to get in on the real action, you need to enroll in a well known robotics research institute

is there part 2 to your picture?

is this good practice or are there better methods for low cost?

Sand filters remove particulate matter but not bacterias and toxins. There's large scale(reserviour) purifications methods that uses micro-organisms for water treatement but I'm rather skeptical that this vat would do that as opposed to just being a sand filter.

>average more sexual partners

So one woman fucks a larger number of men at least once each, on average, than one man fucks a number of women at least once each.

That said, a man could fuck a few women a lot (5x26), then settle down, and a woman could fuck a lot of men (49) once each, one 26 times, then settle down. 130 for man in 5, 75 in 50 for woman.

Once settled down, their sex would [except for cheating and le :^) cuckoldry] grow equally.

In theory, women could have more partners, and men more sex

Think of 3 people. One girl, 2 boys. The girl fucks both boys.

Now the girl has had sex twice and each boy has had sex once.

Now the average number of partners for the woman is 2 and for men it is 1.

Scale that up to like 7 billion. Capeesh?

>>7793286
Maybe I'm retarded, but it's fucking obvious they have to be lying on the survey or the survey sample is too small. It should always be 50:50

Whenever you add a new sexual partner to set of unique sexual partners for one gender, logically you have to add to the other because that pair hasn't slept with each other yet.

Suppose you have 10 men and 10 women (so 50:50 split approximate like the real world)

Let's number each sex 1 to 10
>Women 1 sleeps with men 1-5: Total sexaul partners 5
>Women 2 sleeps with men 6-10: Total sexaul partners 5

Average sexual partners for males: 1
Average sexual partners for females: [math]\frac{5 \times 2}{10} = 1.0[/math]

So far each man has only had sex with 1 women, now repeat for women 3 and 4
>Women 3 sleeps with men 1-5: Total sexaul partners 5
>Women 4 sleeps with men 6-10: Total sexaul partners 5

Let's say the rest of the women become disgusted by the promiscuity of this hypothetical planet and become nuns.

Average sexual partners for males: 2
Average sexual partners for females: [math]\frac{5 \times 4}{10} = 2.0[/math]

Obviously you can draw the pattern here, it's always the same, so let's try the scenario where fewer men get poon, accelerate the pattern this time


Let's number each sex 1 to 2
>Women 1 sleeps with men 1-2: Total sexaul partners 2
>Women 2 sleeps with men 1-2: Total sexaul partners 2
>...
>Women 10 sleeps with men 1-2: Total sexaul partners 2

Average sexual partners for males: [math]\frac{2 \times 10}{10} = 2.0[/math]
Average sexual partners for females: 2.0

Can some mathfag draw up a proper proof or contradiction?
