    Historical Antecedents

    Ancient Era
    Compass
    The first compass was invented by China
    during the Han Dynasty between the 2 nd
    century BC and 1st century AC. At first,
    it was not used for navigation but for
    geomancy and fortune-telling by the
    Chinese and it was called the “South
    Pointing Fish”. It was during 1050 when the said compass was used
    for navigation. It was made of magnetized needle that was
    connected to a piece of wood or cork that swam freely in a dish
    of water. The designated end of the needle would point toward
    magnetic north when it settled.

    Medieval Era
    Eyeglasses
    It was in Italy at around 13th
    century when Salvino D’Armate made
    the eyeglasses who was called as
    the “inventor of spectacles” in
    Santa Maria Maggiore church in
    Florence. It was made of Medieval
    glass-blown lenses where these were
    put into wooden or leather frames and then held in front of the
    face or perched on the nose. These early spectacles included
    convex lenses that may cure hyperopia
    or farsightedness as well as
    presbyopia, which is a typical sign of
    aging.

    Modern Era
    Computer
    The first computer was invented by Charles Babbage between 1833
    and 1871. In 1833, he discovered that a far more generic design,
    an Analytical Engine, was conceivable after working on his
    breakthrough difference engine, which was meant to help in
    navigational computations. Programs and data were to be fed into
    the machine through punched cards, a technology that was popular
    at the time for controlling mechanical looms like the Jacquard.
    The device would feature a printer, a curve plotter, and a bell
    for output. The machine could also punch numbers onto cards,
    which could then be read later.
