Mechanics is, of course, the study of how things move - how an electron moves down your TV tube, how a baseball flies through the air, how a comet moves round the sun. Classical mechanics is the form of mechanics developed by Galileo and Newton in the seventeenth century and reformulated by Lagrange and Hamilton in the eighteenth and nineteenth centuries. For almost three hundred years, it seemed that classical mechanics was the form of mechanics, that it could explain the motion of all conceivable systems.
