More often than not, a piece of mathematics worked out years before—and believed to be totally without practical value—finds a role in the “real” wor… - Ivars Peterson

Randomness, chaos, uncertainty, and chance are all a part of our lives. They reside at the ill-defined boundaries between what we know, what we can know, and what is beyond our knowing. They make life interesting.

Ramsey theory implies that complete disorder is impossible. Somehow, no matter how complicated, chaotic, or random something appears, deep within that morass lurks a smaller entity that has a definite structure. Striking regularities are bound to arise even in a universe that has no rules.

Most coincidences are simply chance events that turn out to be far more probable than many people imagine.
