I don't think I did actually. And as a metaphor for the relational model it doesn't work anyway. The relational model doesn't purport to model REALITY, it purports to model DATA.

I don't think I did actually. Wol was arguing that Classical Mechanics "doesn't tally with reality" period.

In everyday life, the deviations of reality from the Classical Mechanics model just don't matter. They only matter to cosmologists and particle physicist, who form a small (which is not to say unimportant) minority. That is what esoteric MEANS. Look it up!
