Does light entirely perish the darkness? The answer is no‚ it does not. With everything light is casted upon‚ darkness looms in its shadows. It is just one of nature’s many ways of balancing the universe out; black matches white‚ light goes with dark and good balances evil. Nature has many ways of neutralizing the world so that it is forced to harmonize together in order to create an aesthetically interesting environment. Ever notice how on a blazing sunny day‚ there is always a shadow lurking behind

In Shakespeare’s play A Midsummer Night’s Dream‚ metaphors concerning the moon‚ flowers‚ and Cupid are prevalent and have a significant impact on the play. The play focuses on a romantic situation between four Athenians: Hermia‚ Lysander‚ Helena‚ and Demetrius. As the story unravels‚ many comparisons are made to enhance the language and the messages that the characters try to convey. The moon is personified as a chaste woman who can be both gentle and fiery. Flowers are used as romantic symbols with

Troubleshooting fiber Fiber optic cable was once reserved for high-performance needs‚ but today it’s turning up in all kinds of networks. If you’re familiar with copper cable‚ you’ll quickly discover that fiber optic cable is a completely different animal. Not only is the installation process different for fiber‚ but also the troubleshooting process. Fiber optic cable is also far more fragile than copper cable‚ so there are more potential causes of trouble. I’ll discuss common fiber optic cable problems and

lamps‚ in automobiles as rear-window and brake lights‚ and on billboards and signs as alphanumeric displays or even full-color posters. Infrared LEDs are employed in autofocus cameras and television remote controls and also as light sources in fiber-optic telecommunication systems. The familiar light bulb gives off light through incandescence‚ a phenomenon in which the heating of a wire filament by an electric current causes the wire to emit photons‚ the basic energy packets of light. LEDs operate

very little chromatic dispersion because of it narrow spectral output. Lasers are ideal for fiber optics because of the speeds and accuracy. Lasers are more appropriate in single-mode fiber because of its narrow spectrum. Laser transmitters are also used in Laser level finders. Laser level measures the level of the ground and returns the data. LEDs would be more efficient is multimode fiber optic cabling because it has a broader spectrum than single-mode. LEDs are used in television remote controls

TELECOMMUNICATIONS In 1997 Michael O’Dell‚ the chief scientist at World-Com‚ which owned the largest network of “Internet backbone” fiber optic cable in the world‚ stated that data traffic over the Internet was doubling every hundred days. This implied a growth rate of over 1‚000 percent a year. O’Dell went on to day that there was not enough fiber optic capacity to go around‚ and that “demand will far outstrip supply for the foreseeable future.” Electrified by this potential opportunity‚ a number
