This is all obvious. a) No actual "in life" measurement is exact, there is always a measurement error. 4 miles east + 4 miles east = 9 miles east +/- some measurement error, which is always uncertain past some number of significant digits. Which should remind you of the issue of accuracy vs. precision, the misunderstanding of which leads to such absurdities as claiming that a 3.45 grade point average is better than a 3.44 average. Ironically, it's the truths of "regular arithmetic" that enable one to understand why these numbers are absurd. b) 4 miles east plus 5 miles west is not 9 miles northwest. c) 4 pints of water plus 5 pints of ethanol do not produce 9 pints of vodka. Etc. wolf k.

The math curriculum varies quite a bit between jurisdictions, and . What I in mind is the fact that around grade six most of us have formed a world picture, and find it more or less impossible to change it as puberty rebuilds our brain. Cranks are merely the most extreme examples of this: while most people seem content to say "Well, that's something I don't understand", cranks try to disprove what they don't understand. cheers, wolf k.

Curt is using "you" as the generic pronoun, more formally expressed by using "one", as in "One must not assume that "you" means oneself." cheers, wolf k.
