The Four Steps to the Sky

In the Shang Dynasty, the order of the 64 hexagrams was rearranged and recorded in

Taiji () represents one, and the traditional Taiji diagram represents the complementarity of yin and yang; one divides into two, separates yin and yang, that is, two appearances; two divides into four, that is, four images: the sun, Shaoyang, Shaoyin, Taiyin; four points Eight is eight trigrams; two eight trigrams overlap to form eight eight trigrams.However, some scholars pointed out that historical data show that the hexagrams in divination were already 64 hexagrams when they first appeared, but the eight trigrams are the interpretation of later generations.

The sequence of the hexagrams is derived from Hetu Luoshu and the Eight Diagrams of Heaven and Heaven, and is divided into upper and lower classics.It embodies the idea of ​​a round sky, a moving sky and a quiet earth.

There is a widely circulated view in China that the binary of modern computers comes from Chinese gossip, but this has long been proven to be a myth.Regarding this mistake, Guo Shuchun pointed out on page 461 of the book "Liu Hui, the Great Master of Mathematics in the Ancient World": There is a saying in China that "Zhouyi" created binary. As for Leibniz, influenced by "Zhouyi", he created binary and used it in computers. The myth is even more widely circulated.

The fact is that Leibniz invented binary first, and later saw the gossip in the "Book of Changes" rearranged by scholars of the Song Dynasty brought back by missionaries, and found that the gossip can be explained by his binary.Therefore, it was not Leibniz who invented binary after seeing the yin and yang gossip.

Pages 14 to 18 of Liang Zong's masterpiece "Allusions to the History of Mathematics" have a more detailed investigation of this historical case, and those who want to know more can refer to it.

Binary itself has addition, subtraction, multiplication and division calculations, conversions between binary and decimal and other bases, and so on.Binary is completely different from Yin-Yang Bagua. Yin-Yang Bagua does not have addition, subtraction, multiplication and division operations at all, and there is no conversion with other bases.Treating yin-yang and gossip that are only superficially similar as binary actually commits the fallacy of what the great physicist Feynman called the idiot science.
