Judging from its Yin-and-Yang structure, the Book of Change (I-Ching) was most likely founded on binary logic; and judging from the historical texts of the I-Ching, that logic must have been lost thousands of years ago. In this book Dr. Dang-Son builds a geometric model of the Yin Yang theory and uses it to reconstruct the meanings of the 64 hexagrams. When he compares these reconstructed meanings against those recorded in the I-Ching, the agreement is both puzzling and remarkable. Could it be that Dr. Dang-Son has stumbled on the lost scientific code of the I-Ching? You'll be the judge!
