After eight days of backpackin...

After eight days of backpacking with my wife, we were looking pretty scruffy. One morning she came to breakfast in a baseball cap, her shoulder length hair sticking out at odd angles.
"Darling," she said, "does my hair make me look like a water buffalo?"
I thought for a moment, then said, "If I tell you the truth, do you promise not to charge?"

Sir George Biddell Airy

Died 2 Jan 1892 at age 90 (born 27 Jul 1801). English astronomer and mathematician who became the seventh Astronomer Royal (1836-92). In his life he studied interference fringes in optics, made a mathematical study of the rainbow and computed the density of the Earth by swinging a pendulum at the top and bottom of a deep mine, determined the mass of the planet Jupiter and its period rotation, calculated the orbits of comets and cataloged stars. He designed corrective lenses for astigmatism (1825), the first that worked. His motivation was his own astigmatism. Airy had a long-standing battle with Babbage. In 1854, the conflict continued between the two during the battle of the incompatible railway gauges in England. Airy championed the railway narrow gauge and Babbage for the wide gauge.
