What's your favorite transcendental number?

The one I gave the name koppa.

I forgot about that, but now I've written a program that evaluates it to arbitrary precision (using the first method). Below are 1,000 decimal digits (scream for more digits and/or other bases).

0.

Did you check its continued fraction representation?

I second that. The Gelfond-Schneider theorem is one of the most beautiful in all of mathematics.

The Golden Ratio

Interestingly enough, I first read about it in astronomy magazine (yep, even galaxies are ruled by it). Then read further on the net - damn, that's my fav number.

It’s not transcendantal, because it’s the solution of a polynomial equation.
My prefered might be Liouville’s number, aka 0.12345678910111213141516…

No. Is it cool?

The thing I really like about this number is when you look at it geometrically. The area enclosed within a little loop between two curves (with no straight edges) is equal (up to a factor of two) to a series of little rectangular blocks underneath one of those same curves.

I should also confess that I didn't do the proof of the identity myself, but just suggested a few ideas for it. It used induction with two parameters, IIRC, and relied on a lot of terms being zero.

I love e. I memorized it up to 2.71828182845904523536028747...


My favorite number is Euler's Constant (lower-case gamma). Nobody knows if it is even irrational. I made a t-shirt of it.

Not really. All I can tell is that its geometric mean appears to approach Khinchin's constant (another nice number, though it's unknown whether it's irrational or transcendental).

Good one.

On a related note, what's your favorite transcendental function? Mine is the Gamma function.

The area of the mandelbrot set isn't known to be transcendental, though, is it?

Gamma is pretty hot. Without it, the factorial function wouldn't be continuous. I'm a fan of Riemann zeta, as well.
