  • Who Is George Claude Pimentel's Contribution To Chemistry?

    June 18, 1989 in Kensington, California (General Chemicals, n.d.). Pimentel’s Work While Pimentel was knowledgeable in many aspects of Chemistry, his main focuses in the field were infrared spectroscopy, chemical lasers, molecular structure, free radicals, and hydrogen bonding. Pimentel impacted the subject of Chemistry because of his invention of the chemical laser, his modern technique of matrix isolation in low-temperature chemistry, and his three-center four-electron bond model. Pimentel’s chemical laser works on energy obtained by chemical reactions; these lasers can have a continuous wave output and are high powered, sometimes reaching megawatt levels. The most common uses for the chemical laser are cutting and drilling (General Chemicals, n.d.). Another one of Pimentel’s major contributions to the field of Chemistry was his “development and exploitation of the matrix isolation method for the spectroscopic detection of unstable molecules;” this method led to the discovery of highly reactive molecules that scientists would not have been able to identify under other circumstances (Bancroft Library Staff, 2010). Dr. Pimentel was adamant about sharing his love and knowledge of chemistry with the public which lead to him writing and publishing numerous books and journal articles. Some of his most recognized books include: Chemical Bonding Clarified Through Quantum Mechanics, and Understanding Chemical Thermodynamics. In Chemical Bonding Clarified Through Quantum Mechanics,…

  • Laser Fact Or Science Fiction

    Fact or Science Fiction: Could Lasers become Viable Weapons in Modern World? When I say the word ‘laser’, what is the first thing that comes to your mind? Perhaps, like the majority of people, your brain jumps straight to the science fiction. For decades, since 1898 when HG Wells novel War of the Worlds swept the nation, lasers have been popular within the genre of science fiction. From lightsabers, to ray guns it seems lasers have been imagined as a myriad of different weapons. This…

  • Creative Writing: Wilderness On The Lake, Wisconsin Dells

    Pasha’s room had a jacuzzi, Angelina’s room and mine, our own bathroom, Jessica and Pasha had their own bathroom, too. There was a kitchen, a table to eat at, a living room, and there was a washer and dryer. The first game that we did was go-karts and it was so wild! I was so scared because I was going fast, I kept bumping to the sides, and I was last place in the end, but the breeze felt good and the go-karts were so fun and crazy!! Angelina could still use her go-kart pass, but she can’t go…

  • The Importance Of Photometry In The Laser Interferometer

    some useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important application of interferometry is in the Laser Interferometer Gravitation wave Observatory(LIGO) which is used to detect gravitational waves predicted by Einstein.1.1 The LIGO interferometer is like the Michelson Interferometer as shown in…

  • Refractive Surgery: Lasik Surgery

    Astigmatism. Nearsightedness (myopia) is when you can see nearby objects clearly, but distant objects seem blurry. Long-sightedness (hyperopia) is when you can see distant objects clearly, but nearby objects seem blurry and Astigmatism causes overall blurry vision. In most cases, laser eye surgery is pain-free and is completed within 15 minutes for both eyes. It takes 24 hours to see improvement in vision without eye glasses or contact lenses.…

  • Kinect V2 Case Study

    value is calculated as the center of the circle. The difference between the mentioned average depth value and the true depth value is defined as depth accuracy. Specifically, by denoting the depth values measured by a Kinect v2 as a set Formula Md , and the true distance between the planar surface and Kinect as Formula , the depth accuracy can be computed by the following equation Depth accuracy = d − mean(Md ) (3.1) where Mean(.) computes the mean value of (.). To compute the depth accuracy, a…
