thermodynamics,some rotational dynamics.The physics in the middle applies over a huge range,

A series of sails or blades mounted around a rotor catch the windand translate its kinetic energy into rotational energy.Traditional windmills use that rotational energy to grind wheat or pump water.

and translate its kinetic energy into rotational energy.Traditional windmills use that rotational energy to grind wheat or pump water.But in modern wind turbines, it turns a generator that creates electricity.

but push through a bigger angle every stroke,which makes a faster rotational speed, and gives you an effective high gear.So what's exciting about this system

when you rotate the organism around its center point.It's a lot like the rotational symmetry of the triangle we watched earlier.But when it occurs in animals,
