Each evening bird-lover Tom st...
Each evening bird-lover Tom stood in his backyard, hooting like an owl. One night, an owl called back to him. For a year, the man and his feathered friend hooted back and forth. He even kept a log of the "conversation."
Just as he thought he was on the verge of a breakthrough in interspecies communication, his wife had a chat with her next-door neighbor.
"My husband spends his nights... calling out to owls," she said.
"That's odd," the neighbor replied. "So does my husband."

Heinrich HertzBorn 22 Feb 1857; died 1 Jan 1894 at age 36. Heinrich Rudolf Hertz was a German physicist who was the first to broadcast and receive radio waves. He studied under Kirchhoff and Helmholtz in Berlin, and became professor at Bonn in 1889. His main work was on electromagnetic waves (1887). Hertz generated electric waves by means of the oscillatory discharge of a condenser through a loop provided with a spark gap, and then detecting them with a similar type of circuit. Hertz's condenser was a pair of metal rods, placed end to end with a small gap for a spark between them. Hertz was also the first to discover the photoelectric effect. The unit of frequency - one cycle per second - is named after him. Hertz died of blood poisoning in 1894 at the age of 37. |
