The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor.
Today, the world is swimming in oil, and prices have been sliced in half over the past year. âPeak oilâ theory for production is predicated on the work of legendary geologist M.King Hubbert, who in 1956 employed his now famous/infamous âHubbert curveâ to predict U.S. petroleum production would peak in 1970.
