Isaac Newton

Today was Isaac Newton's birthday in 1643 (adjusted for calendar changes from Julian to Gregorian). He made one of the most important contributions to modern science including the Three Laws of Motion.

- Unless acted upon by an unbalanced force, an object will maintain a constant velocity.

- The alteration of motion is ever proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. -- If a force generates a motion, a double force will generate double the motion, a triple force triple the motion, whether that force be impressed altogether and at once, or gradually and successively. And this motion (being always directed the same way with the generating force), if the body moved before, is added to or subducted from the former motion, according as they directly conspire with or are directly contrary to each other; or obliquely joined, when they are oblique, so as to produce a new motion compounded from the determination of both.

- All forces occur in pairs, and these two forces are equal in magnitude and opposite in direction.

There is so much more that can be said about Isaac Newton, but that would take pages and pages.

Honeysuckle has been experimenting with some of the practical applications of these laws. As I walk across the room, she darts out and jumps on me. Very unnerving for a senior member of the fur club!

I like the 'inertia' law the best...
