Life in Motion

Carousel in motion. (Click picture for larger view and a dizzy sensation) Posted by Picasa
"I feel the carousel starting slowly
And going faster and faster: desk, papers, books,
Photographs of friends, the window and the trees
Merging in one neutral band that surrounds
Me on all sides, everywhere I look.
~ John Ashbery (b. 1927), U.S. poet, critic. "Self-Portrait in a Convex Mirror."
If the world were perfectly free of friction, this carousel would adhere to Newton's Three Laws of Motion:
  • Lex I: Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare.

    ~ "An object at rest or traveling in uniform motion will remain at rest or traveling in uniform motion unless acted upon by a net force."

  • Lex II: Mutationem motus proportionalem esse vi motrici impressae, et fieri secundum lineam rectam qua vis illa imprimitur.

    ~ The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction.

  • Lex III: Actioni contrariam semper et aequalem esse reactionem: sive corporum duorum actiones is se mutuo semper esse aequales et in partes contrarias dirigi.

    ~ All forces occur in pairs, and these two forces are equal in magnitude and opposite in direction.
But the world isn't perfect. Friction exists. We hold on. Life ebbs and flows. The carousel spins; sometimes fast, sometimes slower and if we are lucky and hold on tight, we may end up with a fabulous ride.

Submission for LensDay topic "kinetic".

I found Newton's Laws in Latin, Nyssa. I'm sure you'll tell me if there are any mistakes. Spellcheck should have fun with this.;-)
