    COMPLEX NUMBER CALCULATOR OPERATIONAL
    January 8, 1940 - Bell Laboratories, U.S.A.

    George Stibitz's Complex Number Calculator was functional. He was a research mathematician at Bell Laboratories, who worked on its construction from Apr 1939, assisted by Samuel Williams. Later known as Bell Labs Model I Relay Computer, it used telephone relays and coded decimal numbers as groups of four binary digits (bits) each. It has been called the first electromechanical computer for routine use. A demonstration of its ability in remote computing was given on 11 Sep 1940, when messages were exchanged by phone lines between teletypewriter operators. Calculations suggested by attendees of the American Mathematical Society's meeting at Dartmouth College, Hanover, New Hampshire were communicated to an attendant at the keyboard of Stibitz's calculator in New York.

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.
