Coincidence may be described as the chance encounter of two unrelated causal chains which-miraculously, it seems-merge into a significant event. It provides the neatest paradigm of the bisociation of previously separate contexts, engineered by fate. Coincidences are puns of destiny. In the pun, two strings of thought are tangled into one acoustic knot; in the coincidental happening, two strings of events are knitted together by invisible hands.

Arthur KoestlerNobody before the Pythagorean had thought that mathematical relations held the secret of the universe. Twenty-five centuries later, Europe is still blessed and cursed with their heritage. To non-European civilizations, the idea that numbers are the key to both wisdom and power, seems never to have occurred.
