The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
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.Glenn Gould
As a teacher and parent, I've had a very personal interest in seeking new ways of teaching. Like most other teachers and parents, I've been well aware painfully so, at times that the whole teaching/learning process is extraordinarily imprecise, most of the time a hit-and-miss operation. Students may not learn what we think we are teaching them and what they learn may not be what we intended to teach them at all.betty edwards
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.john maynard keynes
[ 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.
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.werner heisenberg
