In Over Two Months

Earl and Bubba are quietly sitting in a boat fishing, chewing tobacco and drinking beer when suddenly Bubba says, "Think I'm gonna divorce the wife... she ain't spoke to me in over 2 months."

Earl spits overboard, takes a long, slow sip of beer and says, "Better think it over... women like that are hard to find."

Gustav Robert Kirchhoff

Born 12 Mar 1824; died 17 Oct 1887 at age 63.German physicist who, with Robert Bunsen, established the theory of spectrum analysis (a technique for chemical analysis by analyzing the light emitted by a heated material), which Kirchhoff applied to determine the composition of the Sun. He found that when light passes through a gas, the gas absorbs those wavelengths that it would emit if heated, which explained the numerous dark lines (Fraunhofer lines) in the Sun's spectrum. In his Kirchhoff's laws (1845) he generalized the equations describing current flow to the case of electrical conductors in three dimensions, extending Ohm's law to calculation of the currents, voltages, and resistances of electrical networks. He demonstrated that current flows in a zero-resistance conductor at the speed of light.
