Return of an old favourite: Newton's cradle (aka Newton's balls).

No matter what anyone else says, that guy was a gross oversimplifier if ever there was one. bounce

Newton's First and Second laws, in Latin, from the original 1687 Principia Mathematica.

Wiki:

Newton's laws of motion are three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries, and can be summarized as follows:

First law: Every body remains in a state of constant velocity unless acted upon by an external unbalanced force. This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant velocity.

Second law: A body of mass m subject to a net force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.

Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneous.

The three laws of motion were first compiled by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica, first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

Hmm. Can't spot any loopholes so far...

William Blake's Newton (1795)

"To myself I seem to have been only like a boy playing on the seashore, and diverting myself and now and then finding a smoother pebble or a prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me."
~Newton

"The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see nature all ridicule and deformity... and some scarce see nature at all. But to the eyes of the man of imagination, nature is imagination itself."
~Blake

Part of the beauty of oversimplification is the absence of loopholes.

Sir Isaac Newton in a 1702 portrait by Sir Godfrey Kneller.

Nature and Nature's Laws lay hid in Night.
God said, Let Newton be! and all was Light.

(Alexander Pope)

...or perhaps not...

Newton's Alchemical studies sound pretty off the wall: the search for the Philosopher's Stone, Biblical prophecy, the Temple of Solomon etc. Here's the Wiki link to Newton the Occultist:

http://en.wikipedia.org/wiki/Isaac_Newton's_occult_studies

...and here's Newton's rather suspicious personal coat of arms:



After purchasing and studying Newton's alchemical works in 1942, economist John Maynard Keynes opined that "Newton was not the first of the age of reason, he was the last of the magicians."
