    TRANSISTOR HEARING AID
    December 29, 1952 - Elmsford, NY, U.S.A.

    The first transistor hearing aid went on sale, the model 1010 manufactured by the Sonotone Corporation in Elmsford, NY, U.S. It weighed 3.5-oz, measured 3"x1.5"x0.6" and cost $229.50 (about $1500.00 today). It was a hybrid device consisting of two sub miniature pre-amplifier tubes and a single transistor as the final audio amplifier to benefit from the low power consumption of transistors. The reason for the hybrid design was that the first junction transistors had signal to noise ratios which were inferior to tubes. Within months, transistor production techniques were improved largely eliminating noise, so the hybrid model was shortly discontinued.

    HEREO BLACKS LAND SEIZED
    December 29, 1948 - South Africa

    Rev. Michael Guthrie Scott, who lived in South Africa, besieged the United Nations for justice regarding 30,000 Hereo blacks who had their land and rights taken away. Rev. Scott got sympathy from the U.N., but did not get any concrete action on behalf of the Hereos.

    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.
