DAGUERROTYPE
February 9, 1839 - French Academy of Science
The daguerreotype photo process was announced at the French Academy of Science. Previous photographic processes required hours of exposure, but the daguerreotype (named after its inventor Louis Daguerre) needed only a few seconds. The plate was prepared with a layer of photo-sensitive silver halide, was exposed, developed using mercury vapor, and fixed in a solution of sodium hyposulphite. The image remains delicate, and must be protected under glass against damage by touching. The daguerreotype was produced with a direct positive image, needing no intermediate negative, but thus could not yield multiple reproductions made possible by later photographic processes.
THE BEATLES
February 9, 1964 - Ed Sullivan Show, U.S.A.
For the first time ever, the popular music group the Beatles had appeared on the Ed Sullivan Show. Shortly afterwards, they played their first American concert at the Coliseum. The Beatles had come a long way-literally. They originated from England, and were told that they "could not carry a tune across the Atlantic". In the early days they were though of to be no more than a fad. That of course was proven wrong many times over.

More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)

about Eyesight Myth and Fact
Myth: Staring at a computer screen all day is harmful to the eyes.
Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.
