The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa. Werner Heisenberg
Very soon I discovered that if one gets a feeling for no more than a dozen other radiation and nuclear constants, one can imagine the subatomic world almost tangibly, and manipulate the picture dimensionally and qualitatively, before calculating more precise relationships. Stanislaw Ulam
We speak of people "taking refuge" in vagueness - the more precise you are, in general the more likely you are to be wrong, whereas you stand a good chance of not being wrong if you make it vague enough. J. L. Austin
Social physics never can pretend to discover laws which will verify themselves in every particular, in the case of isolated individuals. The science will have rendered a service sufficiently vast, in giving more precise views upon a host of points, of which vague glimpses only were before possessed. Adolphe Quetelet
Architecture arouses sentiments in man. The architect's task therefore, is to make those sentiments more precise. Adolf Loos
Such discussions help us very little to enjoy what has been well done in art or poetry, to discriminate between what is more and what is less excellent in them, or to use words like beauty, excellence, art, poetry, with a more precise meaning than they would otherwise have. Walter Pater
