Quotation by John Allen Paulos

Speedometers, for example, may be digital and give a numeric readout, or analog and produce a lengthening rectangle (or rotating pointer). The analog output is less precise, but puts one's speed in some perspective. An 82 and a 28 are almost indistinguishable, but a long rectangle is quite distinct from a short one, and if its length is changing, that too is manifest. The same trade-off is present with clocks and watches, digital timepieces producing precision, but lacking in all the associations a clockface can engender.
