I think that if I were required to spend the rest of my life on a desert island, and to listen to or play the music of any one composer during all that time, that composer would almost certainly be Bach. I really can't think of any other music which is so all-encompassing, which moves me so deeply and so consistently, and which, to use a rather **imprecise** word, is valuable beyond all of its skill and brilliance for something more meaningful than that -- its humanity.

Too large a proportion of recent "mathematical" economics are mere concoctions, as **imprecise** as the initial assumptions they rest on, which allow the author to lose sight of the complexities and interdependencies of the real world in a maze of pretentious and unhelpful symbols.

[ Fuzzy logic is ] a logic whose distinguishing features are (i) fuzzy truth-values expressed in linguistic terms, e.g., true, very true, more or less true, or somewhat true, false, nor very true and not very false, etc2.; (2) **imprecise** truth tables; and (3) rules of inference whose validity is relative to a context rather than exact.

The more precise the measurement of position, the more **imprecise** the measurement of momentum, and vice versa.

A person with **imprecise** ideas can understand little and be of less help to others.

The more precise the measurement of position, the more **imprecise** the measurement of momentum, and vice versa.

— Variant translation: The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa.As quoted in "The Uncertainty Principle" at the American Institute of Physics
