I've always turned to mathematics with regard to finding peace amidst chaos, specifically prime numbers. There's a nice aphorism by Paul Erdős, the Hungarian Mathematician: "God may not play dice with the universe, but something strange is going on with the prime numbers."
We've all be told that the prime number sequence is random (chaotic). Except that it isn't entirely. There is order (peace) to be found at certain places in the sequence (3,5,7, for example). Ever since Euclid we've know that there are infiniately many prime numbers. And now we know that these small sequences of order (the3-5-7s of the prime number sequence) can also be found infinitely.
The prime numbers hint at what I'd call a middle ground that lies somewhere between chaos and peace, and I think it's a magical place. Mathematicians sometimes call it pseudorandomness.
A process that seems random, but in reality isn't. For me - my life - I call that hindsight!
