It's not entirely surprising. For one thing, Archimedes built some amazing mechanical weapons back then (as well as calculated mass and put "leverage" into scientific context).
For another, there is a **reason** that our language calls them planetary gears, historically.

"For another, there is a **reason** that our language calls them planetary gears, historically." Neat. Hadn't thought of that.

Planetary gears are named that because the gears themselves are arranged to orbit around a central point, not just to calculate the orbits of planets.
