    HOVERCRAFT
    July 25, 1959 - English Channel

    A hovercraft crossed the English Channel for the first time. Having been shipped to France by tender, the world's first all metal hovercraft, SR.N1, crossed the Channel between Calais and Dover in 2 hours 3 minutes on 25th July with Captain Peter Lamb piloting, Mr John Chaplin as navigator and the inventor, Mr. (later Sir) Christopher Cockerell in his own words as 'moveable ballast' on board. It was 50 years to the day that Louis Blériot made the first crossing of the Dover Strait by aeroplane.

    CAROUSEL
    July 25, 1871 - USA

    The first U.S. patent for a carousel was issued to Willhelm Schneider of Davenport, Iowa (117,336). It was described as a two-story "'carrousel' or rotary pavillion used in public parks or other places of amusement." A staircase within the central supporting frame enabled access to the upper story. Radial partitions could provide separate "apartments" with a sofa, imitation horse or other seats. It could be turned by a person or other apparatus. However, it was not very practical or successful. Carousels had been popular for a long time. The earliest* on record was at a fair held at Philippopolis, Turkey on 17 May 1620. The first* on record in England was at the St. Bartholomew Fair in 1729.

  • 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, Gaylord Nelson

That'as where all the economic activity and jobs come from. These biological systems are the sustaining wealth of the world...."

    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.

As we all know, toothaches and any type of oral injury can be extremely painful and should be seen by a dentist immediately. Dental emergencies should be seen immediately by a dentist, day or night. These emergencies include broken teeth, teeth that have been knocked out, or teeth that have been forced out of the socket. With some emergencies, the cheeks, lips, or gums will have cuts or abrasions on them from where the teeth come out of the socket.

If you've had a tooth recently knocked out, the first thing you should do is look for that tooth. When you've found the tooth, gently scrub it to get rid of any dirt or debris. Once you have cleaned it, you should place it back in your mouth between the cheek and gums. Whatever you do, you should never try to put it back in the socket. If you can make it to the dentist in time, he may be able to put the tooth back in place.

If you've had a tooth come out of place, you can normally reposition it with your fingers. You shouldn't use a lot of force, simply because it could damage the tooth. You shouldn't force the tooth into place, rather try and jiggle it around. You can also use moist tissue to hold the tooth in place, until you can get to a dentist.

If you've got a fractured tooth, the treatment will all depend upon how bad the booth has been fractured. No matter how light the fracture may be, it is very important that you get to a dentist as soon as you can. Minor fractures aren't that bad, as they can normally be smoothed out using sandpaper. Sometimes, the tooth can also be restored with a composite. Either way, you'll need to make sure that you use extreme caution with the tooth for the next few days.

The more moderate fractures, normally include damage to the dentin, pulp, and even the enamel. These fractures can be nothing to worry about at times, yet painful with other cases. Providing the pulp hasn't been damaged, your dentist will be able to restore the full shape and function to the fractured tooth. In cases where pulp damage has occurred, the dentist may need to do a root canal or other type of serious surgery to repair the tooth.

Whenever you encounter a dental emergency, you shouldn't hesitate to contact a dentist immediately. Your dentist will be able to assist you, fix the problem, and stop the pain. Dental emergencies can happen at any time, so you should always the emergency number of a dentist who will be there at a moments notice. Tooth pain can be very excruciating – and you'll obviously want to get the problem fixed immediately.
