Citáty Hermann Grassmann

„I define as a unit any magnitude that can serve for the numerical derivation of a series of magnitudes, and in particular I call such a unit an original unit if it is not derivable from another unit. The unit of numbers, that is one, I call the absolute unit, all others relative.“

—  Hermann Grassmann

Zero can never be a unit.
