Kinetic Theory A theoretical approach which attempts to explain the behavior of physical systems using the assumptions that the systems are composed of large numbers of atoms/molecules/particles in vigorous motion, that energy and momentum are conserved in collisions of these particles, and that statistical methods can be applied to deduce the behavior of such systems.
Maxwell's equations The set of four equations, attributed to James Clerk Maxwell, that describe the behavior of both the electric and magnetic fields, as well as their interactions with matter.

 Mechanism
When Watt was designing his double-acting rotative engine in 1780, mill owner James Pickard of Birmingham patented an improved rotative atmospheric engine, using a flywheel to maintain the rotation, and a crank to convert reciprocating motion to rotary motion.
There was certainly "prior art" here, as cranks had long been used on foot-operated lathes and spinning wheels.
My Wimshurst machine uses an open and a crossed O-ring drive on the same shaft to turn the two induction wheels at exactly the same speed.
