1864, Rising Pyramid multiplied billion equals 14,967,000 miles, the distance between the Earth and the sun, and orbit that passes through the center pyramid divides continents of the world into two equal halves completely, and that the basis of the pyramid divided by twice the height gives us a fixed number famous circuit (3.14) contained in calculators. And the four corners of the pyramid is heading to the four original trends in accuracy so amazing that some scientists to the presence of a small angle deviation from the original actors, but after the discovery of modern electronic devices to measure proved to be the corners of the pyramid is more correct and accurate.
