Futures gold interest rate:1In the middle of the 3rd century, the mathematician Fabrance wrote a book and put forward some strange combinations of numbers. The combination of these strange numbers is: 1, 1, 2, 3, 5, 8, 13, 2 1, 34, 55, 89, 144, 233 ┅ (former In this series, any number is the sum of the first two numbers: 2 = 1+ 1, 3 = 2+ 1, 5 = 3+2, 8 = 5+3 ┅, and so on.

The wonder of this series is that the ratio of any two adjacent numbers is 0.6 18! Please try it: 55/89 = 0.6 18, 89/ 144 = 0.6 18, 144/233 = 0.6 18 ┅. Also, this set of numbers is very interesting. The reciprocal of 0.6 18 is 1.6 18. For example,144/89 =1.618,233/144 =1.618,0.618.

Some people say that Fabrance got these figures by studying the pyramids. Pyramids are closely related to the above singular numbers. The geometry of the pyramid has five faces and eight sides, and there are thirteen layers in total. From any side, you can see three levels. The length of the pyramid is 58 13 inch (5-8- 13), and the percentage of high bottom and bottom is 0.6 18. In addition, the length of any side of the pentagonal pyramid is equal to 0.6 18 of the diagonal of the pentagonal pyramid.
