The teacher noticed that Johnny had been day dreaming for a long time. She decided to get his attention."Johnny," she said, "If the world is 25,000 miles around and eggs are sixty cents a dozen, how old am I? "Thirty-four," Johnny answered unhesitatingly.
The teacher replied "Well, that's not far from my actual age. Tell me...how did you guess?"
Oh, there's nothing to it," Johnny said. "My big sister is seventeen and she's only half-crazy."

Thomas Corwin Mendenhall

Born 4 Oct 1841; died 23 Mar 1924 at age 82.American physicist and meteorologist who was the first to propose the use of a ring pendulum for measuring absolute gravity. From 1889 to 1894 he served both as Director of the U.S. Coast and Geodetic Survey and also Superintendent of the U.S. Standard Weights and Measures where he oversaw the shift in the fundamental standards of the U.S. from the English yard and pound to the international meter and kilogram. Mendenhall devised a quarter second's pendulum for gravity measurements and instituted improvements in the measurement of base lines with wire tapes, in the construction of instruments for precise leveling and in the methods used in triangulation and gravity work, and developed a comprehensive plan for the study of terrestrial magnetism.
