TODAY IN HISTORY
HEREO BLACKS LAND SEIZED
December 29, 1948 - South Africa
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.
TRANSISTOR HEARING AID
December 29, 1952 - Elmsford, NY, U.S.A.
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.

Happiness
by Thomas Jefferson
"...Our greatest happiness does not depend on the condition of life in which chance has placed us, but is always the result of a good conscience, good health, occupation, and freedom in all just pursuits...."
by Earth Day, Thomas Alva Edison Inventor
"...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

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.
