    COLDEST TEMPERATURE ON EARTH SURFACE
    August 9, 2010 - Antartica

    the record low surface temperature in Antartica was -135.8ºF (-93.2ºC), colder than the freezing point of dry ice. It was determined from analysis of remote-sensing satellite data later announced on 9 Dec 2013 at the annual meeting of the American Geophysical Union. The location was in pockets scattered near a high ice ridge between Dome Argus and Dome Fuji, two summits on the East Antarctic Plateau. August is winter in the Southern Hemisphere, and the temperature resulted from the geographical nature and weather conditions in the pockets. The World Meteorological Organization official records are for air temperatures made a couple of meters above the surface. That recorded lowest temperature, made in Jul 1983 at the Vostok Research Station, Antarctica, remains at -128.6ºF (89.2ºC).

    PROTECTOGRAPH
    August 9, 1904 - New York, U.S.A.

    The Protectograph check-writing machine was patented under the title Printing-Stamp by Libanus McLouth Todd of Rochester, New York (U.S. Patent No. 766,853). It was designed to protect against check forgers by marking and embossing the amount on a check, thereby preventing the amount thus shown to be later dishonestly changed to a higher value. The apparatus had co-axial printing wheels with lines of raised type forming a series of numbers and suitable words. A check would be placed between the wheels and a platen. An inked felt-covered roller applied ink to the type as the wheels were turned to select the chosen imprint. The platen surface had a yielding material, such as rubber. When actuated by a hand-lever, it was raised from beneath the check and embossed the paper against the type.

  • 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...."
  • 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. This radical change in the principles, opinions, sentiments, and affections of the people, was the real American Revolution...."

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.
