Madame Metrology sat on a wall, Madame Metrology had a great fall,, and you know the rest. Putting her back together again does get habit forming LOL! The way it's starting to look now, is that Michell's Canonical and the former Metrical world models are inverse and obverse sides of the same coin. I think that is why I now enjoy working with old weights and volume units now more than just linear ones. I liken that to the effect of radio signals very faint and far away, that were once picked up on cat's whiskers and crystal receivers, that can now be amplified by transistor circuits to get a better signal of what was being broadcast. Tiny deviations of linear metrics can be enhanced that way to distinguish what was probably intended from just background noises.
