    EDISON'S PHONOGRAPH
    November 21, 1877 - New York City, U.S.A.

    Thomas Edison announced his invention of his "talking machine" - the tin-foil cylinder recorder that preceeded the phonograph. He appears to have envisioned it as a business dictation machine. In Sep 1877, he wrote that its purpose was "to record automatically the speech of a very rapid speaker upon paper; from which he reproduces the same Speech immediately or years afterwards preserving the characteristics of the speakers voice so that persons familiar with it would at once recognize it." The indented tin foil, however, would survive only a few playings. By the first public showing of a phonograph, which took place in New York City in early Feb 1878, its practical applications had not yet been realized.

    WIRELESS TELEPHONE AT WHITE HOUSE
    November 21, 1919 - White House, U.S.A.

    President Wilson used a radio telephone set up on the south portico of the White House to direct the maneuvers of a dozen army airplanes flying over the Potomac river several miles away. His telephoned directions went direct to the flight commander in the air. The instrument was similar to those used by American aviators in France in the latter part of World War I. Col. C. C. Culver actively developed the equipment. He began the project in Aug 1910. No new invention was needed, only adaptation and adjustment of existing techniques. By Aug 1916, he was able to send a radio telegraph signal from a plane. Enlisting expert help from the telephone companies, by Oct 1917, voice messages could be send between a plane and the ground. The system was put into service for military wartime use.

    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. More vehicles
    about Stolen On New Year's

    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?)

Many people most of the time travel. It's not a great think but when you are traveling with your pet that time you need to concentrate more on your pet which may disturb you to enjoy your vacation.

If your pet is very young or old, or is ill, pregnant, injured recovering form surgery then avoid to take them with you as is such time they need more concentration and if you really wish to carry your pet in your vacation then consult with pet sitter rather than take a chance on injuring your pet by taking it with you. If you are in doubt, ask your veterinarian. If your pet has not traveled before, try a short overnight or weekend trip first.

Before you leave inform your veterinarian where you will be traveling to, for how long, as well as whether your pet will be traveling by air or car. Ask about any flea, heartworm, or tick risks for areas you will be traveling to. If your pet becomes carsick or restless when traveling, ask veterinarian about appropriate medications or treatments.

Many times while traveling it happen we get separated from our pet and they get panic so try to avoid such type of situation for traveling safely with your pet. Your pet should wear a safety collar all the time with a tag showing proof of rabies vaccination and your name address, phone number in case your pet becomes separated from you.

To take care of your pet when away from home try to keep fresh water available and don think of changing their die all of a sudden. Make sure your pet is accustomed to the crate before you begin your trip.
