Deciding to buy Xoom Android, hoping surprise

Thinking how our universe was created based on these figures?

There is a very old figure which was found by old Chinese in a river, and the figure tells people what is the universe? and how universe created? In the long history of China, Chinese smart people invented and updated Ba-Gua (八卦) based on the figure, and use Ba-Gua to guide their lives.

Fewer people could realize that our computers are related with Ba-Gua. Ba-Gua is retrieved from binary system (0 and 1), and "0" represents "阴", "1" represents "阳". Computer is only one application of Ba-Gua, which is verified by modern sciences. I think there will be huge number of applications which will be based on Ba-Gua in future lives.

Chinese people create great cultures in the world, and the cultures can guide people to  reach a very very happy life. What is the origin of the Chinese culture? Its "易". "易"  is also the origin of the universe. Thinking about it.

This is a plane structure of Ba-Gua, which consists of time, space and human being. The system is keeping turning all the time. 

This figure tell us relationships between numbers and Ba-Gua. It considers "5" as base number, 1,2,3,and 4 are beginning numbers and 6,7,8,9 are resulting numbers. 5 is in the middle of the system, and it represents earth. Chinese people thought every thing in the world are generated based on the earth. So 5 is important for people. 1+5=6; 2+5=7; 3+5=8; 4+5=9. This is the perfect decimal system.

Before 7,000 years, we had the matrix, which was based on "river figure". We could see sum of all columns and rows including crosses are 15. It is very beautiful, and very perfect. Math is always beautiful.
