    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.

    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?) Harvard Medical School
    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.

RC hobby, which is taking up RC toys as a hobby, can entertain and give you a fun-filled experience. These RC toys are taking the spotlight for a great hobby, not only for kids but also for adults. It's never too late to try one as more and more people are getting into this kind of hobby. Amongst the various types of RC toys, RC Helicopter is the most popular nowadays.

With the ongoing of the technological enhancements, flying a RC helicopter is fun and very affordable. With only about $60, you can have your own dream to fly a RC toy. Another benefit of an RC hobby is that these toys do not release harmful fumes than the other helicopter models and types release. Thus, the pilot and the onlookers will always be safe from harmful chemicals. It's always said that it's easier to fly than any other models. Most RC helicopters are ready to use and fly after the purchase; you don't need to assemble anything anymore.

The usual RC helicopter needs at least four controls. One is called the Roll or the Cyclic Pitch, the Elevator control, the Rudder, and the Collective Pitch or Throttle. You can then control the height of the flight, the steadiness of the course, and some experts like to do an acrobatic control with their RC hobby crafts. RC toys are best played in an open field where you can observe their every move and route. However, RC Helicopters are better than RC airplanes because helicopters don't need a runway to fly, you can definitely fly it anywhere, even in your backyard or inside the house.

The care and maintenance of this kind of toy is not as complicated as you think. It is a technical hobby so you also have to learn some technical tips to better care for your RC toy. The battery life is an important thing to know how to stretch the limit. Before charging it again after it drained, let it cool down first for about 15 minutes before hooking it up to charge. In this way, you will help the battery have a break and not overuse it. Before using the toy, make sure that the screws and bolts are secured in the proper places to avoid any unexpected accidents with your RC hobby craft. If something is not right, like the presence of a weird sound that you have not heard before, you have to stop using it and have it checked first with an expert to avoid sudden breakdown of your RC toy. And when keeping the item, put it in a place where it is wide and has enough room for your helicopter to prevent scratching or unwanted pressing on the item.

There are many types of RC helicopters to choose from if you want to buy one. The Mini RC Helicopters are the smallest, inexpensive, and very durable. It's better to start with a smaller helicopter first as you begin to practice to control the RC toy. The Coaxial Helicopters are more complicated to control since it has 4 channels to control. This one is good for those who want to develop a hobby for flying helicopters. If you've already developed a flying skill, then the 3D Helicopter is the one for you, since it can perform a lot of new tricks and acrobatic moves.
