Federal Bureau Of Investigation Cause Of Death
2,200 wordsForensics is defined as the application of science to interpret clues for crime investigation. The earliest forensic scientists were physicians who were called upon to give an opinion as to the cause of death in individuals. Now most of the forensic scientists are investigators that pick up clues at the crim scene. Because criminals often are not the brightest people on the planet they often do not plan out a burglary or theft and carelessly leave behind district clues that allow an investigator...

Laser Beam B M
1,776 wordsImagine a world without traffic jams; where there would be no delay for work, no worries about travel schedules and above all no public appraisals from the English teacher for coming late to the class! Time would finally be stricken off the banal list of worries. This impossible to hit pitch however, lies in a plane where platitude is not well taken. This plane is one where advanced physics and quantum mechanics form frightening webs of reason for everything that happens in that other world - wh...

Subatomic Particles Rene Descartes
1,416 wordsTyler Ross 2 - 28 - 05 Computer Throughout mans existence, we see questions arise upon certain topics. These questions are based upon answers of other questions, and everything becomes based upon itself. But it was Rene Descartes who first decided to doubt, to challenge, and to reject all that could be rejected. Suspicious of all that he was able, and skeptical of all, which might be criticized, Descartes fell upon his famous postulate, I think therefore I am. Although this theorem accounts for ...

Solid State Lasers Beam Of Light
1,749 wordsL A S E R S Did you know that some laser beams are small enough and powerful enough to drill two hundred holes on a spot as tiny as the head of a pin? The first major advancement in laser development came in 1954. This was the year that Charles H. Townes, an American physicist, created a device that amplified microwaves. This device was actually called a maser at first, which was short for Microwave Amplification by Stimulated Emission of Radiation Masers. It produced microwaves of just one freq...

Level Of Reality Subatomic Particles
2,410 wordsIn autumn of 1992, one of the worlds greatest contemporary physicists passed away. David Bohm, whose work inspired many people all over the world, died in London. David Bohm's contributions to science and philosophy are profound, and they have yet to be fully recognized and integrated on the grand scale. David Bohm was born on December 20, 1917, in Wilkes-Barre, Pennsylvania. Bohm was fascinated by the dazzling concepts of cosmic forces and vast expanses of space that lie beyond our understandin...

Beam Of Light Laser Beam
497 wordsHow a CD works Compact disc (CD) players have increasingly replaced the phonograph and the cassette tape. They offer a clear, crisp sound, faint background noise, and have the additional advantage of longer life. In addition to their audio content, some compact discs contain digital graphics that can be displayed on a television screen. To understand how a CD works one must understand what a CD consists of. A CD is about 1. 2 millimeters thick. Most of the CD consists of an injection-molded piec...

Back And Forth Stimulated Emission
1,080 wordsThe light from lasers differs from ordinary light in several important aspects. Ordinary light from a light bulb travels randomly in all directions (unless the bulb is equipped with an integral reflector that directs the light). The light is thus incoherent. Even when incoherent light is directed with a reflector, it still spreads rapidly. The light from a laser is temporary and spatially coherent. This means that all of the wave-fronts of light are lined up in time and space (see Diagrams). The...

Solid State Lasers Beam Of Light
1,373 wordsA laser (LAY zum) is a device that produces a very narrow beam of light. This is called coherent light. It is formed from producing light at equal wavelengths in phase. The result is a beam of light that does not stray from it? s path. Conventional light bulbs produce incoherent light. This form of light diffuses immediately upon radiation from its source. The size of a laser beam varies greatly. Some lasers produce beams that are small enough to fit 200 beams in an area the size of a pinhead. T...
