LIGHT EMITTING DIODES Light Emitting Diodes are electronic components that use the flow of electrons to excite materials into emitting photons of light. A diode is a basic electronic component that allows electricity to flow one way only. The discovery of "light emitting" diodes we believe was an accident sometime around 1907 when a diode in an early radio transmitter was noticed to glow when in use. Incandescent bulbs use resistance in a filament to impede the flow of electricity‚ heating

Why is the Sky Blue? Did you know that the sky wasn’t always blue? The story goes thousands of years back. It all went like this… It was just another day in Aika village. The sky was gray and dim(Put it here or remove it from myth). There weren’t a lot of people walking around town‚ and the only sounds heard were the soft autumn wind and rustling leaves. One girl‚ named Ai‚ was sitting alone on a knoll. Every day she hoped for a change in the village‚ as everything was always dark and gloomy. No

It went off course while going on‚ what should have been‚ a routine trip to mars. On the way it when off course. Over the next Twenty million years the Blue Raccoon drifted through the cosmos‚ until it came upon a planet. This planet was green and had life‚ much like early earth.

Green Technologies Green technology‚ also known as environmental or clean technology‚ minimizes impacts on the environment and natural resources. It’s based on concepts such as conserving water and energy‚ reducing waste and pollution‚ harnessing renewable energy sources‚ finding ways to reuse materials‚ and developing less polluting technologies. Green technology is everywhere these days; in the news‚ politics‚ fashion‚ and of course technology. Green Technology is becoming so widespread

AP English Literature 11 April 2012 Introduction Light Pollution Imagine. You’ve just reached home after a long day at work. You take off your shoes‚ place them neatly against the wall‚ change into loungewear and sink into the couch. Your eyes are weary so you dim the lights and turn on the television. Time passes by and you remain unmoved . Your skin seems attached to the fabric of the couch‚ the TV is low‚ creating a soft rumble to sleep to‚ accompanied by a faint glow in the darkening

Soylent Red is rather less nasty. Another soy product‚ it is versatile enough that it can be made into passable approximations of most grain-based foods‚ and unlike Soylent Yellow‚ it can be described with a straight face as having a flavor. But the masses’ current favorite is the new Soylent Green. With Green‚ the Soylent Corporation has branched out a bit‚ turning‚ according to its advertising literature‚ to the vastness of the oceans for its raw materials— whereas Soylents Yellow and Red are soybean

The speed of light (meaning speed of light in vacuum)‚ usually denoted by c‚ is a physical constant important in many areas of physics. Its value is 299‚792‚458 metres per second‚ a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[2] This speed is approximately 186‚282 miles per second. It is the maximum speed at which all energy‚ matter‚ and information in the universe can travel. It is the speed of all massless particles and
