Stagnant Quotes (4 quotes)
Just as iron rusts from disuse and stagnant water putrefies, or when cold turns to ice, so our intellect wastes unless it is kept in use.
Lives with no more sense of spiritual meaning than that provided by shopping malls, ordinary television, and stagnant workplaces are barren lives indeed.
Suppose a number of equal waves of water to move upon the surface of a stagnant lake, with a certain constant velocity, and to enter a narrow channel leading out of the lake. Suppose then another similar cause to have excited another equal series of waves, which arrive at the same time, with the first. Neither series of waves will destroy the other, but their effects will be combined: if they enter the channel in such a manner that the elevations of one series coincide with those of the other, they must together produce a series of greater joint elevations; but if the elevations of one series are so situated as to correspond to the depressions of the other, they must exactly fill up those depressions. And the surface of the water must remain smooth; at least I can discover no alternative, either from theory or from experiment.
From paragraph in Scientific American (1846) urging the use of water filters. (source)
The fact is generally known that nearly all liquids contain a variety of minute living animals, though in some they are too small for observation, even with a microscope. In others, especially in water that has been long stagnant, these animals appear not only in hideous forms, but with malignant and voracious propensities. we cheerfully and heartily recommend the adoption of filters by all who use this water, from either the public or private hydrants.
