Goldfish burial

Little eight-year-old Nancy was in the garden filling in a hole when her neighbor peered over the fence. Interested in what the youngster was doing, he asked: "What are you doing there, Nancy?"

"My goldfish died," Nancy sobbed. "And I've just buried him."

The obnoxious neighbor laughed and said condescendingly: "That's a really big hole for a little goldfish, don't you think?"

Nancy patted down the last heap of earth with her shovel and replied: "That's because he's inside your cat."

Theodore Maiman

Born 11 Jul 1927; died 5 May 2007 at age 79.Theodore Harold Maiman was an American physicist who built the first working laser. He began working with electronic devices in his teens, while earning college money by repairing electrical appliances and radios. In the 1960s, he developed, demonstrated, and patented a laser using a pink ruby medium. The laser is a device that produces monochromatic coherent light (light in which the rays are all of the same wavelength and phase). The laser has since been applied in a very wide range of uses, including eye surgery, dentistry, range-finding, manufacturing, even measuring the distance between the Earth and the Moon.
