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."

Augustin Jean FresnelDied 14 Jul 1827 at age 39 (born 10 May 1788).French physicist who first investigated the effect of interference of light, with results known as Fresnel fringes. This decisive work, together with further experiments with polarized light, supported Thomas Young's wave theory of light. Fresnel advanced the wave theory by identifying light as transverse waves rather than the longitudinal waves previously assumed by Young and Christiaan Huygens. His pioneering work in optics included showing that white light is composed of a spectrum of innumerable wavelengths ranging from red to shorter violet wavelenths. In 1819, he improved the optical system of lighthouses by replacing metal reflectors with revolutionary stepped lenses of his design.« |
