Light Bulb Grolier Multimedia
1,351 wordsOn October 22, 1879 Thomas Edison created the electric light or what we know of it today as the light bulb. To make a statement like this that Thomas Edison invented the light bulb is both a huge hyperbole and a huge understatement all at the same time. A more correct view is that he perfected a practical light bulb and that his real plan and accomplishment was the invention of an electrical system to produce and distribute electrical power. He did in fact invent a light bulb with the correct fi...

Fiber Optic Cable Fiber Optics
1,581 wordsFiber optics is a cable that is quickly replacing out-dated copper wires. Fiber optics is based on a concept known as total internal reflection. It can transmit video, sound, or data in either analog or digital form. Compared to copper wires it can transmit thousands of times more data (slide 2). Some of its general uses are telecommunications, computing, and medicine. The very first fiber was made in 1870 by the British physicist John Tyndal. In this experiment that he showed to the Royal Socie...

Source Of Energy Problem Of Global Warming
1,596 words... one saying goes - the gust of wind, created by the sway of butterfly's wings, can develop into a storm. At the same time, it opens a theoretical possibility for us to influence weather, for as long as we know all weather-inducing variables. There is also another way of achieving greater reliability of wind harvesting, as the source of energy. The article Wind Power Gathers Speed, which can be found on the site of Australian Academy of Science, gives us an insight on how it can be accomplishe...
