### Re: Perfect Moments In Music

Rach 2, movement I: The restatement of the first theme against the piano's alla marcia theme. Breathtaking, and one of the best musical climaxes I've heard.

Rhapsody in Blue: The Eb grandioso before the restatement of the main theme that ends the piece. Also, the clarinet gliss.

### Re: My number is, in fact, bigger!

The largest possible number is, in fact, 45,000,000,000. No way to beat it, unless 45,000,000,001 is proven to exist.

### Rotating Tesseract Thoughts

Just something I was thinking about while driving home from school. This may already be common sense, so bear with me. I constantly think about how beings that live in 2 dimensions would perceive a cube in an attempt to relate to how we would perceive 4 dimensional shapes like the tesseract. In part...

I DON'T THINK SO.

The last line made me laugh more than it should have.

Also, nice proof. I'll keep this in mind for the next time I see my friend.

### Re: i = -i?

In the second line, an "√-1" appears from nothing, I think it's the greatest error in the first proof. i = /-1 -1 = /-1 * /-1 That's where all three come from. About the second proof, it goes as following: √2*√2 = √-2*√-2 √(2*2) = √(-2*-2) √4 = √4 There's nothing wrong about that. But tha...

### Re: How did you calculate pi?

I would calculate Pi by measuring the circumference and diameter of a circle, and then dividing them. A piece of string is a good thing for measuring the circumference with. Another way you can do it is to measure the volume and radius of a sphere. You could measure the volume by displacing some wa...

### Re: How did you calculate pi?

That said, your geometrical reasoning is right. I wonder if it's possible to get an expression for pi without a hidden pi in it. (Mmmm... hidden pi.) I think you have to avoid using angles, since this will end up introducing pi through the 2π radians in a full rotation. I haven't figured it out aft...

Every respectable math-nerd must have worked out some method for calculating pi at some point, most likely out of boredom. So, what did you come up with? I represented pi as a limit of the perimeter of an infinitely-sided regular polygon circumscribed in a circle with a radius of 1, over 2, which ca...

1 is probably meant to be solved using guess and check style calculations. There are better ways to go about it, the Lambert-W function, but its not something that you should worry about. 2 is a bit tricky. If X = f(x) and you have an equation of the form a(f(x))^2 + b(f(x)) + c = 0, then its a qua...
