Is this guy a savant? I mean, is his brain configured differently? If he is then cool, if he isn't than woah!

Wowoah! I got some crazy answer! It's probably wrong, but let me know if it isn't!

Let C be the midpoint of AB.

Hence,

Hence, the area is inside the curved part

The circumference of the cross section

So the total surface area is:

≈ 1364.43 = 1360 m² (3.s.f)

What you do I think, is that you flick the 1st switch, then turn it off and flick the 2nd switch, leaving the 2nd switch on. Then, go upstairs and check on the lightbulb. If the lightbulb is on, then obviously the 2nd switch is correct. If the lightbulb is off, but still hot, then it is the first switch. If the lightbulb is off and cool, then it must be the 3rd switch.

Hmmm, this is probably counter-intuitive because there is no such thing as a frictionless surface in our real world. Perhaps weird stuff just happens on those surfaces... why don't you try incorporating a little friction into the equation and see what happens.

I always have a tendency to understimate the value of abstracting what you see as geometry into algebraic equations. What I found interesting is that although you have 3 variables and 2 equations, you eventually come out with a numerical answer for x. Is that the case often?

Hard... they're so similar, but I prefer the 2nd one, especially its simplification of the links on the left.

Hmm I just came up with an ill-advised hypothesis:

There is no clearly defined 'boundary' of the universe, that is to say, it is infinitely large. Therefore, couldn't it have been possible that the universe has been here all along, but just that all the stars and planets erupted from one explosive from a point in this forever-existing universe? The observations by Hubble just state that everything is moving away from each other. This doesn't mean that it is the universe is expanding, it might not have anything to do with that?

Since (x-1) and (ax^2 - bx + c) are both factors, simply divide

You should get

If you wait a sec, I'll draw up an image showing the division.
