    EINSTEIN ADDRESS
    January 27, 1921 - Prussian Academy of Sciences, Berlin

    Albert Einstein suggested the possibility of measuring the universe, which startled the audience, with his address Geometry and Expansion given at the Prussian Academy of Sciences in Berlin. Applying certain results of the relativity theory, he came to the conclusion that if the real velocities of the stars (as could be actually measured) were less than the calculated velocities, then it would prove that the real gravitations' great distances were smaller than the gravitational distances demanded by the law of Newton. From such divergence, the finiteness of the universe could be proved indirectly, and it would even permit the estimation of its size.

    ARTIFICIAL SWEETENER PATENT ISSUED
    January 27, 1970 - U.S. Food and Drug Administration

    James M. Schlatter received a patent for “Peptide Sweetening Agents” (U.S. No. 3,492,131), an invention which eventually led to the marketing of aspartame under the name NutraSweet. The patent was filed 18 Apr 1966, assigned to his employer, G.D. Searle & Co. In Dec 1965, a few months before filing, he had accidentally discovered the first example of such compounds. To pick up a paper, he had licked his finger. He tasted an unexpectedly sweet trace of a substance that had, he realized, earlier splashed onto the outside of a flask he had handled. It contained L-aspartyl-L-phenylalnine methyl ester. After development and much scrutiny of the testing of aspartame, the U.S. Food and Drug Administration approved it (22 Oct 1981) with many permitted uses as a food sweetener.

  • The Revolution
    by John Adams

    "...The Revolution was effected before the War commenced. The Revolution was in the minds and hearts of the people; a change in their religious sentiments of their duties and obligations.

  • 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...."

    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.

References to the guitar more or less in its modern form date back to the 14th century. In its infancy it had four courses of double strings and a rounded body like a gourd or a pumpkin. Its mother would not recognize it today!

Around the sixteenth century the guitar was a popular musical instrument amongst the middle and lower classes of Europe, and as it increased in popularity it began to undergo a change of shape. Luthiers began making instruments with single strings instead of courses and experimented with its form until, by the 19th century, the body of the guitar was made wider, and flattened out. In the twentieth century the wooden tuning pegs which adjusted the tension of the strings were replaced by metal machine heads. Now we have the shape that the modern electric guitar is based on.

The first electric guitars were made in the 1930's in response to a demand from guitarists in bands whose rhythmic stylings could not be heard above the other instruments. The main problem with these electric guitars was that feedback was coming through the amplifier from the vibration of the guitar's body. This challenge began the evolutionary process of the solid body electric guitar.

The early electric guitars had sound holes in the body that were smaller than the sound holes of conventional guitars. In 1924 Lloyd Loar, an engineer with the Gibson factory, used a magnet to change guitar string vibrations into electrical signals, which could be amplified through a speaker. Now it was possible to build guitars that did not possess sound holes but could be heard clearly through an amplifier. Amateur guitar players were able to get their hands on electric guitars through the efforts of Paul Barth, George Beauchamp and Adolph Rickenbacker who founded the Electro String Company in 1931. Their guitars resembled steel guitars, and were played in the guitarist's lap using a slide.

Modern electric guitars are made of many thin layers of wood glued together. The top layer is often a more attractive wood to give the guitar a pleasing appearance, and the other layers are of a wood which gives a good tone such as poplar or ash. The use of laminates endows the instrument with the robust body and tonal quality that would be impossible in one piece of wood. The original solid body guitar was however, made from one piece of wood. In 1941 Les Paul turned a railway sleeper into an amplified stringed instrument. He called it "The Log". When production of his instrument began he stayed with the conventional guitar shape to give his market a familiar image to relate to. Les Paul's invention marketed as the Gibson Les Paul is still extremely popular.

In the 1940's, the Fender Broadcaster Electric guitar came into the world. Nobody really noticed until Arthur Smith used a Broadcaster to record "Guitar Boogie" in 1949. After being renamed the Telecaster, it was put on the market in 1950. Another Fender model, "the Stratocaster, caught guitarists" attention with its distinctive tone and light weight. It's still the second most popular guitar in the world.

Ibanez, Jackson, Paul Reed Smith, ESP and Yamaha have made solid body electric guitars with original designs, distinctive shapes and new materials mixed with modern technologies to produce more efficient and versatile electric guitars. Today's electric guitars produce tones varying between futuristic music or quasi-acoustic sounds.

In the 1960's, effects boxes introduced fuzz, delay, echo and the wah-wah sound to the arsenal of sounds available to the modern guitarist. A pedal operated by the guitar player's foot turns the effects on or off. Now guitars contain software that lets guitars sound like other types of guitars or reproduce the sound of other musical instruments. With developments like the latest self-tuning guitars, maybe the old joke about a guitarist' phoning in, a solo will become a reality!
