I fully understand this, cheers.....but, as I said to Ron Kean, my problem was with the whole idea of a universally applicable uncertainty threshold, which (I perceived) was presented as unbreakable - no matter what measurement and tracking technology (even subatomic) was implemented.
P.S. Euclidean Space ?
