cults3d
Epicyclic gearing was used in the Antikythera Mechanism, circa 80 BC, to adjust the displayed position of the moon for the ellipticity of its orbit, and even for the apsidal precession of its orbit. But In 1588, Italian military engineer Agostino Ramelli invented the bookwheel, a vertically-revolving bookstand containing epicyclic gearing with two levels of planetary gears to maintain proper orientation of the books. What is bookwheel?? The bookwheel is a type of rotating bookcase that allows one person to read multiple books in one location with ease. So what's next? Bevel gear or Herringbone gear?
