Antoher spelling bee word. piezometer "piezo-" is a root meaning pressure. One very important word is "piezoelectric". My marvelously accurate watch has as its heart a tiny quartz crystal in an oscillator circuit which has a truly remarkably constant frequency of vibration. Divider circuits reduce frequency to one beat per second, and the rest is obvious.

i have uses a piezometer-- a very simple one. in xerox machines, (specifically the 1048 copier, which made 2 sided copies) sheets that had been copied once tended to not lie flat, (they had a residual electrial charge) to correctly position and feed them for side 2, they were pulled into position by a vacuum motor.
you needed to be able to test and adjust if need, the vacuum, and used a piezometer to do so... it measured the air pressure! (to little, the paper tended to curl and feed crooked, to much, and it could jam) hi musick and satin!
