[Blindmath] physics/mathematics problem; have a solution?

[Tami Kinney]

Steve,

I was just thinking of my upcoming best-seller: The Physics of 
Do-It-Yourself Cane Training and Other Things. /lol/

While I have yet to experience any dire results of physics while 
traveling at poodle speed, I have every confidence that when I get 
around to it, the effects of physics on anatomy will be truly 
impressive. /grin/ Undoubtedly, this will render the object behind the 
impact incapable of counting her fingers and toes, thus saving her from 
calculating the true degree to which she was acted upon by the laws of 
physics.
