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:
“It doesn’t matter that your painting is small. Kopecks are also small, but when a lot are put together they make a ruble. Each painting displayed in a gallery and each good book that makes it into a library, no matter how small they may be, serves a great cause: accretion of the national wealth.”
—Anton Pavlovich Chekhov (1860–1904)
“All good music resembles something. Good music stirs by its mysterious resemblance to the objects and feelings which motivated it.”
—Jean Cocteau (1889–1963)
“Living in cities is an art, and we need the vocabulary of art, of style, to describe the peculiar relationship between man and material that exists in the continual creative play of urban living. The city as we imagine it, then, soft city of illusion, myth, aspiration, and nightmare, is as real, maybe more real, than the hard city one can locate on maps in statistics, in monographs on urban sociology and demography and architecture.”
—Jonathan Raban (b. 1942)
