170 1 year, the German mathematician Leibniz learned about China's Book of Changes through the French missionary Bowett, and got two pictures of Zhouyi from the missionary. At that time, mathematicians were studying and inventing binary, and this binary mathematics (0, 1) was the basis of the algorithm language of electronic computers. \n Mathematicians, inspired by China's Book of Changes, were surprised to find that the arrangement of 64 hexagrams in the Book of Changes was consistent with their own binary mathematics from 0 to 63. \n\n 1703 Inspired by China's Book of Changes, Leibniz wrote a paper on binary arithmetic, which was published in the Proceedings of the Royal Academy of Sciences. This is the foundation of epoch-making electronic computers. \ n \ n \ Later, the German mathematician proudly said that he revealed the mystery of reading thousands of books, that is, the Book of Changes contains binary mathematics. For this reason, a famous German mathematician wrote to the then Emperor Kangxi of China, asking for naturalization in China. In order to express his admiration for China I Ching, he established a China College in Frankfurt.
