    HAND-HELD CALCULATOR
    February 1, 1972 - United States

    The first scientific hand-held calculator was introduced for $395 by Hewlett- Packard, named the HP-35 for having 35 keys. It was the first hand-held calculator able to perform logarithmic and trigonometric functions with one keystroke. The red LED display could give scientific notation up to 10 digits mantissa and 2 digits exponent. The price was reduced several times, eventually to $195. By Feb 1975 (when production of the model was discontinued), 300,000 had been sold. The numbers and functions for calculations were entered in “Reverse Polish Notation”(RPN), which used an “ENTER” key but needed no parentheses or “=” key. It ran on rechargeable batteries and had electronics with several integrated circuits in a 79 ×147×34 mm (3.1" x 5.8" x 1.4") case.

    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. More vehicles
    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 :

The article is dedicated to the description of radio controlled cars based on the remote control system, their types, designation and ways of exploitation.

ARTICLE CONTENT :

Radio controlled trucks, or RC cars as they are commonly referred to, are a fun way of spending time both for children and adults. Their work is founded on a system of remote control. One more type of remote control trucks is wire connection cars, but radio controlled cars are more popular. Radio controlled trucks are usually divided into two groups: toy model trucks produced for children and hobby-grade model which is designated for adolescents and adult people.

These 2 versions of radio controlled cars are different, but still have something in common. Both of them constitute copies of real vehicles and are controlled through radio control. But there're a certain number of distinctive differences between these two variants. First of all, a toy variant is a solid plastic representation of the car when at the same time the hobby-grade model is very close to a real-life vehicle in relation to outward appearance and individual parts. The hobby-grade models are designed in the same manner like a real truck.

Furthermore, this variant demands the same service and maintenance like you are the owner of a real life vehicle. There are various methods of powering hobby-grade RC cars. They could be electrically, fuel or even nitro powered. Making a decision which one to take isn't that easy. All the versions have their advantages and disadvantages that should be carefully thought over. For instance, an electric powered RC car will be lighter that a petrol run one, but the first will be slower than the last one.

Whatever the case, these trucks are so intricate, that every enthusiast can change his electric car into a fuel run one, or vice versa, without particular efforts.
What is so particular about hobby-grade radio-controlled cars that attracts attention of numerous men of all ages to them. In general, it's their complexity. It is not a toy, it's actually a real truck, but very small.

Moreover, these radio controlled cars can be used for racing and what man would refuse to feel oneself a racer. It is much more fun than computer games, that is why RC cars are so attractive to adult men.
Evidently, radio-controlled trucks are a wonderful pastime. But still do not forget that it will demand a lot of maintenance, repair and upgrading. So this hobby is quite expensive, but it is a truly unforgettable experience.
