Why don't we just nuke these hurricanes?

You could easily stop these hurricanes from hitting land by cooking them off.

Recently found out that I have an estimated IQ of 143. Is that good? I've seen the Bell Curve diagram, which says I'm in the top 1.3%, but I somehow find that hard to believe.

Jeez it's so fucked up that civilizations master mathematics but were still stuck with primitive tools. In a way I guess maybe we are stupid for not dumping our civilizations knowledge onto some sort of material that isn't paper or digital-something.

Let us consider the subset of the real numbers [0, 1]. That is, all the real numbers between 0 and 1 inclusive. Now suppose, like some people claim, that the number of numbers in that subset is the same as the number of real numbers in total. Now, let's add a chunk of numbers to [0, 1]. For example, we'll throw in the numbers between 1 and 2 to get [0, 2]. Because we added more numbers, it is clear that [0, 2] has more numbers than [0, 1]. We can throw all the rest of the numbers and it is obvious that the number of real numbers is greater than the number of numbers in [0, 1]. But this contradicts our supposition that the number of numbers in [0, 1] is the same as the number of real numbers. Because this is an intrinsic property of the so-called "real numbers," we can conclude that the real numbers don't exist, because it is a construct based on a contradiction.

but some infinities are greater then others and its simply depends on how small of a piece of break it into

cardinality ≠ number of the things when infinity is concerned.
They have the same cardinality because you can make a bijection between them, in this case;
f: [0.1] -> [0.2]; f: x -> 2x
As you can see our function is injective (for each value in the co-domain there is at most one value in the domain which maps there) and surjective (each value in the co-domain is covered by at least one value in the domain)
∴ It is a bijection
As f is a bijection from [0.1] to [0,2] they must have the same cardinality even though the concept of count is meaningless for infinite sets

Why do electric cars only have 1 gear?
22 posts and 4 images submitted.
>>
>>9153235
Because gearing is unnecessary. You wouldn't need gears on an internal combustion engine setup either if they could handle the broad range of torque and speed an electric motor can.
>>
>>9153235
why the fuck would you need a gear ? you get all the power at any angular velocity of the wheels .making shit that requires gears is kinda stupid in comparison .

Yeah but changing gears at redline rpm is cool

The "force" with electricity and current for charge.
Special relativity rather satisfyingly shows it as a manifestation of electric force.

Could a nuke destroy a storm?

I could imagine a big enough bomb disrupting the flow of a storm and even heating up the air around enough in order to take its fuel away.

Apart from possible tidal waves, would this work?

No.
>>
It could work but you would need an absurdly large bomb, to the point that the bomb would do more damage than the storm would have
>>
>>9153218

Not at sea. Also, I don't think you would really need that big of a bomb to weaken the storm, which is what you want to do anyway.

hi summer

bi summer

I've been programing for some time in other languages, but now I'm trying to learn how to write code in C++ using Microsoft Visual Studio 2015 and get used to the IDE. I really enjoy learning throught practice so I need some algorithms that can implement.

Literally any algorithm. From factorials to Monte Carlo.
