齿轮

To avoid the new thinking of Copernicus that the sun is the center and the earth moves around it once a year and turns on itself once a day, to keep the old thinking of Ptolemy, earth at the center, you need this complicated system of interlocking spheres and gears.

为了排除哥白尼的新理论，也就是：太阳的宇宙中心，地球每年绕日公转一周每天自转一周，并维护托勒密旧学说也就是：以地球为中心，你需要这套球体与齿轮纠缠的复杂系统。
