The [DiFFERENCE] between SPEED and VELOCiTY:

$$ o o o vector
$$ o o o PROjECTiON
$$ A--------VELOCiTY vector v-->B - - - - - -> C
$$ o o o
$$ o o o
$$ o o ..ANY actual PATH o
$$ GUESS *SPEED* is CLEARLY, (..ANY actual PATH) / DURATiON.
$$ VELOCiTY v is ANY measured or imagined VECTOR / DURATiON.
$$ [CLEARLY, POSiTiON B is an ARBiTRARY point, ON the PATH].
$$ Any OTHER 2 points on the *SAME path* a DiFFERENT VECTOR.

xxein: Do I have to think about Heisenberg if I already understand
more than he could explain? That was a yesterday to me.

My access is acting funny. I don't know if I posted or not. Please
excuse any duplicates.
