overtone

Part of the formal training of machinists in the US is the pronunciation of numbers, critical in machining to avoid ambiguity. The word "and" is used only to locate the decimal point - 1101.01 is read "one thousand one hundred one and one hundredth", and no other way. (n.b. among machinists, 1101.0011 is read "one thousand one hundred one and eleven tenths). btw: Water ice is not the only solid less dense than the corresponding liquid - among the elements alone, gallium, germanium, and bismuth expand when solidifying. Several compounds do that as well.
