The pitch drop experiment is a long-term experiment which measures the flow of a piece of pitch over many years. Pitch is the name for any of a number of highly viscous liquids which appear solid, most commonly bitumen. At room temperature, tar pitch flows at a very slow rate, taking several years to form a single drop.

—Michel de Montaigne (1533–1592)
“In order to cultivate yourself and to drop no lower than the level of the milieu in which you have landed, it is not enough to read Pickwick and memorize a monologue from Faust.... You need to work continually day and night, to read ceaselessly, to study, to exercise your will.... Each hour is precious.”
—Anton Pavlovich Chekhov (1860–1904)
“I have been trying all my life to like Scotchmen, and am obliged to desist from the experiment in despair.”
