3.14 pi bookmark bookmark

The design of the π(pi) bookmark was inspired by a crop circle that appeared near Barbury Castle in Wiltshire, England in 2008. The circle gradually followed a certain pattern, with a step appearing at every specific distance. Later astrophysicist Michael Glickman noticed that a small dot near the center of the pattern is actually equal to the decimal point in our mathematics. At the same time, according to the division method of the steps, we can vaguely see that the strange circle is secretly divided into ten equal parts. The appearance of each step represents a number. Taking the center point to the first step as an example, it contains three equal parts, so it represents 3, and from the first step to the second step There is only one equal part, so it represents 1. According to this logic, we interpret it in order, and finally we get the value of pi 3.141592654, which is π. The pattern looks similar to ordinary geometric figures, but it contains hidden information. https://static.wixstatic.com/media/df3d5f_9db1b60d4054417992819c0028641fab~mv2.jpg/v1/crop/x_0,y_130,w_500,h_334/fill/w_600,h_400,al_c,lg_1,q_80,enc_auto/cropcircle.jpg
