The Book of Changes -- I Ching in Chinese -- is unquestionably one of the most important books in the world's literature. Its origin goes back to mythical antiquity, and it has occupied the attention of the most eminent scholars of China down to the present day.
The Book of changes is an ancient divination text read throughout the world, providing inspiration to the worlds of religion, psychoanalysis, business, literature, and art.

The principal device of the Timewave Zero theory is a fractal function (constructed using numerical values derived from the I Ching hexagrams) which maps time onto 'novelty' and in this way predicts change.
