lights to pollute the sky around it (Keck, n.d.). Also, the atmosphere in Hawaii for the majority of the year is clear and dry offering the best look at the sky above us. According to Keck’s website, Keck Observatory consists of two optical and infrared telescopes, weighing about 300 tons each. It also has the two largest light collection mirrors on the planet. The first Keck telescope began observing in 1993, while Keck two began in 1996. Engineers at Keck have learned how to establish…

In addition, to fight piracy, movie theaters employ a very popular technology known as infrared spectrum, which projects an infrared beam of light, invisible to the spectators, on the theater’s screen; this equipment does not permit the movie to be recorded by camcorders or video cameras. However, this technology, used by movie theaters to fight piracy, is expensive;…

Currently there are thirteen telescopes that are located near the summit of Mauna Kea, nine of the telescopes are for optical and infrared astronomy, three of them are for submilllimeter wavelength astronomy and one is for radio astronomy. Mauna Kea is a unique site for astronomy because of the atmosphere above the mountain is extremely dry which is great from measuring infrared and submilllimeter radiation. The University of Hawaii has a lease from the State of Hawaii for the land that is…

What is a Computer Mouse? A computer mouse is a small hand-operated input device used to manipulate objects on a computer screen. It controls the movement of the arrow shown on the computer screen. The computer mouse was invented in 1963 by Douglas Engelbart. It was meant to make navigation through the computer easier. The mouse mirrors the movement of the arrow on the computer screen. The computer mouse got its name from its looks. The early version of the computer mouse was a small semicircle…

would decrease the amount of pain and healing caused by the episiotomy. These treatments include: heat in the form of lamps, warm sitz bath, moist packs, and infra-red light therapy. Infra-red light therapy is a form of photo therapy in which the infrared light is directly applied to the episiotomy wound. These rays of light penetrate the skin, helping in the release of nitric oxide thus relaxing the blood vessels and preventing the clotting of blood due to the injury (Kaur, Sagar, Deol,…

hair loss. Their energy loss was measured during a winter month. The effect was measured by the energy lost because parasites by definition causes energy loss for the infected. In order to measure this energy loss, they used infrared thermography and GPS collar. The infrared thermography measures the heat loss by comparing the temperature of the wolves and the temperature of the environment. The GPS collar keeps track of the movement of the animals. Wolves that loss some energy due to the…

More than 150 years ago, the invention of the camera, a now every day item, was made and its later counterparts would be the technology to predict deadly catastrophes and save millions of people. This modern technology is known as remote sensing. The term “remote sensing” was used first by Evelyn Pruitt of the U.S. Office of Naval Research in the 1950s. It is “commonly used to describe science-and art-of identifying, observing, and measuring an object without coming into direct contact with it”…

our human health, the air we breathe, and water supply in our communities. Carbon dioxide (CO2) emitted from auto and factory emissions acts as a blanket, trapping long-wave infrared energy coming off the earth making our planet much warmer. Most radiation is absorbed by the earth’s surface through the ultraviolet and infrared rays of sunlight. Some of the outgoing radiation is trapped by the earth’s atmosphere and warms it. At the same time, some energy from the sun is radiated back into space…

We all know that we have our own unique fingerprints but did you know that you can make sun prints? You may be wondering what a sunprint is, a sunprint is like a unique type of photo made with special sunprint paper that with the help of the sun creates a permanent image. A sunprint is formed when a chemical reaction happens with chemicals inside the paper,but before we talk about that, here is how you make a sunprint. You can make a sunprint by placing an object on a sheet of sunprint paper,…
