    PITOT TUBE
    November 12, 1732 - Academy of Sciences, Paris

    Henri Pitot read a paper to the Royal Academy of Sciences in Paris about an instrument he had invented to measure the flow velocity at different depths of water in the River Seine. It had a scale and two open vertical glass tubes on a wood frame. The lower end of one pointed down, the other bent at 90 facing the flow. The belief of the time was that flow velocity at a given depth was proportional to the mass above it, meaning increasing velocity at greater depth. Recording the difference in liquid levels in the two tubes, he showed the opposite was true. Henri Darcy improved the design, with the support of Henri Bazin. Today, the Pitot tube has an important application in aerodynamics for the measurement of the airspeed of aircraft.

    POLYPROPYLENE
    November 12, 1999 - Bartlesville, Oklahoma, U.S.A.

    In Bartlesville, Oklahoma, a plaque was placed on the site of the laboratory where the polymer polypropylene was invented, designating it a National Historic Chemical Landmark by the American Chemical Society. The first commercially successful use of the new material was in the Hula Hoop®. In 1951, J. Paul Hogan and Robert L. Banks, research chemists working for Phillips Petroleum Company, discovered the polymer unexpectedly during experiments with catalysts while trying to convert the natural gas components ethylene and propylene into compounds useful for gasoline. Later, they also developed a new catalytic process for making high-density polyethylene. Phillips soon invested in new plastic manufacturing plants.

    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.

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!
