   A few comments on the words used in the title of the book and on some related expressions are necessary. A "quantity" is here understood in the sense of "a thing that has the property of being measurable in dimensions, amounts, etc., or in extensions of these which can be expressed in numbers and symbols" (Webster's New World Dictionary of [the American Language], Third Edition, 1988), or of "something having magnitude, or size, extent, amount, and the like" (Random House Webster's College Dictionary, 1991; The New Hamlyn Encyclopaedic World Dictionary, 1988). It is interesting that up to the 1950s a "quantity" was defined as what we now describe as "magnitude" (e.g., the unabridged Webster's New International Dictionary, 1948, gives examples of a sphere's surface being a quantity, its area a magnitude, or a yardstick being a quantity, its length a magnitude). This practice is now obsolete and at present length is a quantity, its numerical value its magnitude.
