VACUUM TUBE

October 20, 1906 - American Institute, U.S.A.
Dr. Lee DeForest (26 Aug 1873 - 30 Jun 1961), one of the “fathers of radio,'' announced his three-element electrical vacuum tube (now known as a triode) to a meeting of the American Institute of Electrical Engineers He had discovered that when a mesh, or grid, of wire was placed between the filament and collector “plate†in a diode tube (first made by J. Ambrose Fleming, 1904), a large voltage-amplifying effect could be produced. DeForest patented this vacuum tube on 15 Jan 1907. The ability of this tube to amplifiy weak signals was an invention as great as radio itself, because it made long-distance communication possible.

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. But here's the truth: Sometimes the more things change, the more they stay the same. And sometimes, oh, sometimes change is good. Sometimes change is everything...."
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 Stolen On New Year's
More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?)
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.
