Small Objects and Maps
Observing a nearby small object without a magnifying glass or a microscope, the optimal distance is 20–25 cm. At this close range, 0.05 mm can be seen clearly. The accuracy of a measurement ranges from 0.1 to 0.3 mm and depends on the experience of the observer. The latter figure is the usual positional accuracy of faint details in maps and technical plans.

Famous quotes containing the words small, objects and/or maps:
“Rome, like Washington, is small enough, quiet enough, for strong personal intimacies; Rome, like Washington, has its democratic court and its entourage of diplomatic circle; Rome, like Washington, gives you plenty of time and plenty of sunlight. In New York we have annihilated both.”
—M. E. W. Sherwood (1826–1903)
“But what is classification but the perceiving that these objects are not chaotic, and are not foreign, but have a law which is also the law of the human mind?”
—Ralph Waldo Emerson (1803–1882)
“And at least you know
That maps are of time, not place, so far as the army
Happens to be concerned—the reason being,
Is one which need not delay us.”
—Henry Reed (1914–1986)
