  • 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...

  • Creatine Monohydrate Muscle Mass
    818 words
    What is it and where does it come from? Simply put, creatine monohydrate is the most popular and effective bodybuilding supplement on the market. Everyone consistently using creatine is making gains in lean mass. There is one good reason why three out of four of the ' 96 summer Olympic medallist's used creatine: it works and it works well. A French scientist first discovered creatine in 1832, but it was not until 1923 that scientists discovered that over 95 % of creatine is stored in muscle tiss...

  • Food Chain Laser Light
    895 words
    LIGHT: A FUNDAMENTAL FORCE IN OUR WORLD If asked what light is, one could say that it's one of the most basic elements of our world and our universe as we perceive it. It is through sight that we receive 90 % of our information. It is through the use of telescopes aiding the naked eye that we are aware of the heavenly bodies around us. It is through light that the energy from the sun is transferred to us. The sun's energy supports the food chain; plants use it to turn water and CO 2 into energy ...

  • Niels Bohr Model Of The Hydrogen Atom
    365 words
    Niels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels. Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies ...

  • Energy Levels Black Holes
    969 words
    The problem of continuum versus discreteness seems to be related to the issue of infinity and finiteness. The number of points in a line served as the logical floodgate which led to the development of Set Theory by Cantor at the end of the 19 th century. It took almost another century to demonstrate the problematic nature of some of Cantor's thinking (Cohen completed Godel's work in 1963). But continuity can be finite and the connection is, most times, misleading rather than illuminating. Intuit...

  • Stimulated Emission Positively Charged
    948 words
    Lasers HISTORY OF LASER PRODUCTION The roots of laser mechanism are very modern. In 1900 German physicist Max Planck presented an explanation of why the colors of a glowing hot body may change with temperature. He also proposed discrete quantum theory saying that radiations come in discrete quantities called quanta. Therefore radiations are not only a series of waves but a stream of particles called photons. By 1917, Einstein has outlined the principles underlying the production of laser radiati...

  • Valence Electrons Electric Field
    1,130 words
    Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It i...

  • Quantum Mechanics Quantum Physics
    1,568 words
    While researching quantum physics, I realized that I had just finished a book that was based on quantum theory. At the time, I didn t quite realize that quantum theory and quantum physics were related except in name. Niels Bohr once said, Anyone who is not shocked by quantum theory has not understood it. He believed this because quantum physics makes the common laws of classical physics false on small scales. First, quantum physics is the physics of the incredibly small. It tries to explain the ...
