Left Side M C
610 wordsWhat you see is not always what you get. We learn to perceive or understand what we " re looking at, and we get used to how things are supposed to be. Sometimes our brains get the clues all wrong. Other times, our brains fill in the missing pieces. Our brains cause optical illusions in both ways. The optical illusion you see the most is probably television. TV doesn't really move. Television is really lots of still pictures that are shown to us very quickly. Our brain puts the images together be...

Amount Of Light Fiber Optics
1,073 wordsEverything You Ever Wanted to Know About dB But Were Afraid to Ask Telecommunications systems used electrical signals and copper wire to transmit voice messages long before lasers, lightwave's and fiber optic cable. To describe and measure power levels in electrical systems, telecommunication engineers used the standard unit of decibels to express gain or loss and relative power levels. Meanwhile, scientists working with fiber optic signals were using units of milli watts (mW) to determine the a...

Focal Length Distant Objects
1,280 wordsLight and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar, " and shops, "viewer. " Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's bands and red...

Radio Telescopes Radio Waves
1,285 words... copes Orbiting telescopes are used to observe the ultraviolet (UV), far infrared, and X-ray portions of the electromagnetic spectrum. The Infrared Astronomical Satellite, placed in orbit in 1983, carried a 22. 5 -inch infrared telescope. Because all matter emits infrared radiation if warm, technologists had to cool the telescope to near absolute zero with liquid helium so its internal heat radiation would not mask radiation it was collecting from deep space objects. Among its many discoverie...

5 Th Century North And South
1,653 words... regions of this early temple are significant. With 6 columns across the front and back and 16 on each side (counting the corner columns twice), the temple has a ratio of length to width of nearly three to one. As time passed, Greek architects felt these proportions were too elongated. They progressively reduced the temples length relative to its width, until by the mid- 5 th century the ratio was slightly more than two to one. The Parthenon in Athens (447 - 432 BC), for example, has 17 colum...

Camera Obscura Human Psychology
1,276 wordsHow do representations of space affect our relationship to a place? To answer this question, we should perhaps ask ourselves an equally important question: how can we probe nature to learn about it without changing it. By analyzing this question using six main representational themes cartographic, political, Cartesian perspectivalism, optical, transcendental, and biological we will answer the original question. I believe that there are no representations of space that would not in some way affec...

Even with 58 Mb / s of throughput this drive still achieves some of the highest transfer rates available today, only outdone by some high end 15, 000 rpm SCSI drives. It has a seek time of only 4. 5 ms which is almost half of a standard 7200 rpm IDE drives seek time. This speed will greatly increase game loading times and provide seamless data tra...

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...

1,139 wordsGene Regulation Using the Lac Operon Abstract Gene regulation in cells has been studied extensively in both eukaryotic and prokaryotic organisms. Gene control is employed as a way of saving the cell energy by only producing those enzymes it needs. In eukaryotes, genes are regulated so as maintain levels of cell specificity. In this experiment, the restriction of the production of the -galactosidase enzyme in the prokaryote Escherichia coli can be achieved by employing the lac operon. This operon...

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...
