    COMPLEX NUMBER CALCULATOR OPERATIONAL
    January 8, 1940 - Bell Laboratories, U.S.A.

    George Stibitz's Complex Number Calculator was functional. He was a research mathematician at Bell Laboratories, who worked on its construction from Apr 1939, assisted by Samuel Williams. Later known as Bell Labs Model I Relay Computer, it used telephone relays and coded decimal numbers as groups of four binary digits (bits) each. It has been called the first electromechanical computer for routine use. A demonstration of its ability in remote computing was given on 11 Sep 1940, when messages were exchanged by phone lines between teletypewriter operators. Calculations suggested by attendees of the American Mathematical Society's meeting at Dartmouth College, Hanover, New Hampshire were communicated to an attendant at the keyboard of Stibitz's calculator in New York.

    BLACK AMERICAN INVENTION
    January 8, 1872 - U.S.A.

    A second U.S. patent was issued to Black American inventor Thomas Elkins for a new article of chamber furniture which he designated a "Chamber Commode" (No. 122,518). It provides a combination of "a bureau, mirror, book-rack, washstand, table, easy-chair, and earth-closet or chamber-stool," which might otherwise be constructed as several separate articles. Previously, a patent had been issued to Elkins on 22 Feb 1870 for a "Dining, Ironing Table and Quilting Frame Combined" (No. 100,020). Another patent was subsequently issued on 11 Apr 1879 for a "Refrigerating Apparatus" for "food or corpses," which provides a convenient container and method of chilling using the evaporation of water.

    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?)

ARTICLE INFORMATION :

Natural, safe ways to preserve dental health and oral hygiene.

ARTICLE CONTENT :

HOLISTIC DENTISTRY People often talk about preventative medicine and mention, quite rightly, the need for correct diet, exercise and certain nutritional supplements. But many pathogens and subsequent conditions can originate in the area of the mouth. Whilst the enzymes contained in the mouth's saliva are powerful enough to fight off many toxins, they cannot eradicate all unwelcome visitors. In addition, many people have amalgam fillings which contain mercury. If this mercury leaks into the body's system there can be a host of unpleasant consequences, the most common among them being Candida.

As mercury is essentially a poison, any presence of it in the blood can also increase the workload of the liver, which again may have a number of ramifications. Dentists who embrace a natural approach to oral hygiene and dental health are, in general, in the minority. The field of complementary medicine can provide a huge number of options for the dentist seeking to augment his approach and achieve a higher degree of efficiency. From homeopathy to natural detoxification products, most holistic dentists have found that introducing natural medicinal regimes into their practices has paid dividends.

One particular practice,in Bedfordshire, England, has been utilizing this approach now for almost twenty years. The Luton Holistic Dental Practice use everything from homeopathy to herbal formulas to augment their natural, mercury-free approach to dentistry. Their main dentist, Thomas Nyerges, says, 'We have noticed that recovery time and general response to treatment is remarkably improved when we include natural medicinal supplements as a part of overall treatment.'There are, additionally, numerous testimonials extolling the benefits experienced after mercury removal. Little by little other mainstream dentists are now also beginning to incorporate a more natural approach to treatment, good news for everyone who dreads those visits to the big leather chair!
