Planck's constant is the 
Planck's constant is the natural quantum of this property, which limits the possible states of motion for subatomic particles. The principle of least time developed by Fermat not only minimizes time, but this property as well. Defined as twice the average kinetic energy times the time of measurement or as the average momentum multiplied by the distance moved, FTP, name this six- letter term which explains why projectiles in two dimensions always follow parabolic paths.
