  • Funk And Wagnalls Carbon Dioxide
    941 words
    Carbon dioxide lasers are one of the most powerful lasers ever constructed. The word LASER stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that amplify light and produce light beams, ranging from infrared to ultraviolet. A light beam is consistent when its waves or photons, increase while mixing together. Laser light can be extremely intense, highly directional and very pure in color. Gas lasers such as the carbon dioxide laser is made active by ultraviolet...

  • Solid State Lasers Back And Forth
    2,014 words
    Laser is an acronym for light amplification by stimulated emission of radiation. In the last century many types of lasers have been used for many different applications from welding to surgery to military and even many uses in every day life by harnessing the principles of light and stimulated emission. To understand how lasers work we must first understand the physics behind light waves. Light is emitted from a source and travels in straight lines and when it strikes an object is either absorbe...

  • Magnetic Fields Electric Current
    1,068 words
    In ancient times men knew of a special kind of rock that could pull other rocks of the same kind and pieces of iron toward themselves. Such rocks were called lodestones. Today man uses the same force exerted by electromagnets and permanent magnets to provide magnetic aide to trains and more efficient power generators. This report will focus on the use of magnets in the generation of electricity and magnetically aided trains. Magnetism is defined as the force exerted by a magnetic field. A magnet...

    The first thing that must be cleared up is what is cloning, and what is a clone. A clone is an organism derived asexually from a single individual by cuttings, bulbs, tubers, fission, or parthenogenesis reproduction (" Cloning" , 1997). Pathogenesis reproduction is the development of an organism from an unfertilized ovum, seed or spore (" Pathogenesis" , 1997). So cloning, biologically speaking, is any process in which production of a clone is successful. Therefore, the biolo...

  • Shock Therapy Invisible Man
    834 words
    Ralph Ellison used shock therapy to symbolize the current status of society in his novel Invisible Man. It symbolized: society s lack of morals; the white men s need to control black men and erase their identities, and the way people often lose themselves in technology. Electro-convulsive therapy has been a controversial procedure, ever since its introduction by Dr. Cerletti in 1938. ECT is a treatment for severe mental illness in which a brief application of electric stimulus is used to produce...

    It is not my intention to lay before you a life of Faraday in the ordinary accepting of the term. The duty I have to perform is to give you some notion of what he has done in the world; dwelling incidentally on the spirit in which his work was executed, and introducing such personal traits as may be necessary to the completion of your picture of the philosopher, though by no means adequate to give you a complete idea of the man. Michael Faraday was born at Newington Butts, on September 22, 1791,...

  • Earths Atmosphere Boiling Point
    469 words
    Neon was discovered in 1898 by British chemists Sir William Ramsay and Morris W. Travers as a component of the most volatile fraction of liquefied crude argon obtained from air. Upon applying an electric current to it, the chemists found that it had an orange glow, and they decided that it was not argon, but rather a new element altogether. Neon is not a very common element, but the places it is most abundant in are the earths atmosphere, and trapped within rocks in the earths crust. The place w...
