I feel that it is very natural to include it.

it isnt, it's called computation.

>all of 12 - 18 year old mathematics and early college mathematics is not mathematics

Why isn't it called computation then?

>>7946761
Because it was always called so and the parents would shit on the teachers if they tell them that the symbolic manipulation they struggled their whole life with is not mathematics

I don't know how you would model that since you would need to also find a way to determine what happens to cars and planes. I think the graphene battery would better reduce emissions than nuclear but I'm turbo pro nuclear too so... I would imagine there would be an elastic phase where we would experience a cooling which would held freeze much of the carbon monoxide in the ice and then it would level out by warming a little.
In a perfect world we would have graphene circuits, graphene batteries, graphene solar panels, graphene filters and miniature nuclear reactors to power individual buildings. Think mall, not home. Apartment complex. That kind of thing. Maybe on a per block radius.

It wouldn't expunge CO2 from the atmosphere, nor would it place oxygen, which we need, into the atmosphere.

Due to the density differences CO2 stays under while Oxygen floats away.

Anyway, take the world's amount of electricity prouduced by CO2 emitting production systems and multiply that by .9. There's how much it will've changed.

The sooner you realize you're just a garden variety human being, the better off you will be. Self indulgence is not a positive trait.

no im special

this is old news

If you weren't already uncomfortable with technology in principle, consider reading a bit of Marx.

I'm okay with this. I don't really see an issue.

The same thing could be said about Earth by a person on kepler-452b. Personally I'd rather be here than there.

Nigga in 50 years IUT could be taught to postgrads, "everything is trivial" is the most insufferable meme on this board and the easiest way to spot a high school student.

>>7945397
Because geniuses are people who are extremely smart. That's why we rate them on how smart they are, dumb fuck.

>>7945406
Oh shit I am the dumb fuck.

I think most geniuses ARE judged based on their smarts.

0 is neither positive or negative mate, elaborate.

> to an engineer, infinity equals 1
How fucking more off could you be?

>>7945084
Actually, you pleb, from a mathematical standpoint, that statement is almost correct.

infinity equals -infinity is not almost correct, but literally anything else is.

>it's ok to be almost right! you did your best!

are engineers really this cucktacular? you approximate everything and ignore the discrepancies that physicists and mathematicians have to fan out for you. case in point? look at ductility decrease in steel when temperature dropped in liberty boats. they couldn't figure out how to stop those fractures because their knowledge of materials and physics was so "hurr it's almost correct" tier that they fucking caused boats to sink before they left the harbor. you need to be more strict with your shit when it comes to things like that man.

>Organic beings die, we cant reuse ourselves to create new life but just to give another person a bunch of extra years of empty existence just because the dead was a donor.

Everything dies. The Universe dies eventually. You're only looking at things with the perspective of trillions of years being long. It's not.

This whole premise is just silly. You're deluding yourself into creating a 'purpose' for the universe that's not objective.

>>7944945
You just made myself ask more questions.

It's gonna take a while before machines come even close to being as self-sustaining as organic lifeforms. Machines also have their own vulnerabilities, there is no 'perfect' being.

There it is

Nothing to see here folks, just another retarded CS major flopping around in their own stupidity

Im so sorry for asking pleb questions...

SORRY I FAILED YOU MATH OVERLORD

To understand where the multiplication rules come from, you may think of the set of complex numbers as the set of polynomials in x, where each occurence of x^2 is set to -1.

[math]p(x) := 3-4x+2x^2+7x^3 = 3-4x+2(-1)+7x(-1) = 1-11x[/math]
[math]q(x) := 1-x-3x^2 = 1-x-3(-1)= 4-x[/math]
[math]p(x)·q(x) = (1-11x)·(4-x) = 4 - 45 x + 11 x^2 = 4 - 45 x + 11 (-1) = -7 - 45 x[/math]

And indeed
[math](1-11i)·(4-i)=4-11+(-1-44)i[/math]

The x with the x^2 -> (-1) property is a symbolic tool here.

You may also think of a complex number a+ib as a 2 by 2 matrix ((A11,A12),(A21,A22)).
Then matrix multiplication also leads to i^2=-1. Replace a with ((a,0),(0,a)) and ib with ((0,-b),(b,0)).
Check it.

Although if you watched 100 videos, you will know this already.

Professor of Biology here.
Worth it if you really love teaching and/or are reasonably young and decent looking.
Fortunately, I'm both.

I teach at a small college and we don't exactly get the brightest students, but I receive great satisfaction from exposing their minds to new concepts and ideas. I like to think I'm making the world a little less ignorant every semester.

On the other hand, if you're reasonably good looking and personable, you can score some primo tail. Current gf is a former student, and I have a very beautiful and very eager pupil ready to fuck this week.

Pay isn't bad either.

>>7944535
Sounds good. Do you think teaching at a high school level would be much better/worse? In my country HS teachers get more than Professors in terms of wage.

Difficult to say; here in the US I wouldn't teach K-12 if they tripled my salary. High School kids are little shits, used to being spoon-fed the bare minimum to pass a standardized test. They get no respect from students or their parents.

we shoulda named it "moon penetrator"

>>7944246
Because it sounds cool and plebs don't know the full story.
