The History of the Remote Control: The Downfall of Western Civilization??? By: Kyle History of Technology Research Paper The typical American family has on average four remote controls in their household. Look around the room and count how many you have in your house. I count five in just this room alone‚ not including the wireless mouse and keyboard I am using right now to type this paper. Everyone has seen remote controls for televisions‚ VCRs‚ and stereos. However‚ can you imagine

tunes relatively to this pitch. The piano is the only instrument that tunes slightly higher than A 440. As a general rule‚ it is better to be sharp than flat‚ since flat pitch is more detectable. Because the piano requires hours to tune properly‚ tuners will bring the pitch slightly higher to compensate for the tension placed upon the strings. This helps to keep the piano from falling out of tune. Frequency Doubling All pitches approximately double at the octave. To reach a higher frequency‚

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient‚ hazardous‚ or impossible. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers

Cell Phone Effects on the Human Brain Walking around in school to walking around at the shopping malls with your mobile phone may seem fashionable and trendy‚ but most people do not know that it might be causing you to get a cancer and brain damage threw the loss of memory. Many mobile phone holders do not realize it and it should be something everyone should be aware of. It may seem pretty unusual how a mobile phone can cause a child or an adult to get cancer‚ but it is true. New evidence is

Radio Astronomy Essay In the 1930s a huge discovery was made; one that has led to many subsequent discoveries about the world beyond Earth. This discovery was radio astronomy‚ the study of celestial objects at radio frequencies. Radio and optical astronomy are two different ways to study stars‚ planets and moons in the universe; but the most useful would have to be radio astronomy. Despite this‚ there are some who do argue that optical astronomy is the more useful of the two. Radio waves are a form
