    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.

  • A Change is Gonna Come
    by Meredith Grey

    "...Change; we don't like it, we fear it, but we can't stop it from coming. We either adapt to change, or we get left behind. It hurts to grow, anybody who tells you it doesn't is lying.
