Two college classmates met for

Two college classmates met for the first time in years.
"How goes it with you, Pete?" asked one.
"Not good at all," mourned Pete. "My wife ran away with the mail man, my son is a juvenile delinquent, my bank failed, and all my teeth will have to come out."
"Gosh, I'm sorry to hear that," sympathized the classmate. "What business are you in now?"
"Some old line," answered Pete. "Selling good-luck charms."

Giovanni Virginio Schiaparelli

Died 4 Jul 1910 at age 75 (born 14 Mar 1835).Italian astronomer who is remembered for his observations of Mars over seven oppositions and named the "seas" and "continents". In 1877, he saw on the surface of the planet Mars the markings that he called canali (channels), later misinterpreted as "canals." He made extensive studies, both observational and theoretical, of comets, determining from the shapes of their tails that there was a repulsive force from the sun. He showed that meteor swarms travel through space in cometary orbits. He explained the regular meteor showers as the result of the dissolution of comets and proved it for the Perseids. He suggested that Mercury and Venus rotate on their axes, discovered the asteroid Hesperia (1861) and was a major observer of double stars.
