incandescent lamp became extremely successful due to the advantages it had over its rivals. Before its invention, society was force to use inefficient and dangerous forms of lighting such as arc lights and gas lamps. Compared to its counter parts, Edison’s…

to asphyxiation (suffocation). Xenon “is not considered a carcinogen (cause of cancer) (“Xenon – Xe”). Xenon has little commercial/economic use. However, it is used in “photographic flash lamps, stroboscopic lamps, high-insensitive arc-lamps for motion picture projection and high- pressure arc lamps to product ultraviolet light (solar simulators) (“Xenon – Xe”). It can also be used as a general anesthetic and occasionally on the lights of cars because they are considered to be less…

is this surprising red color on my skin when I go out in the sun? Ew! What is it?A sunburn is a skin response to ultraviolet radiation, which is also known as UVR. Vulnerability to UVR waves may come from the sun, tanning beds, phototherapy lamps, and arc lamps. Symptoms of sunburn may include: Pink/red skin Warm/hot skin Pain,tenderness, or itching Swelling Fluid-filled blisters Headache,fever,chills,or fatigue. UVR waves can be so mean to DNA!The main injury of sunburn is UVR waves harming…

colorful and useful method of advertisement. However, the lights produced an irritating flickering that caused headaches and eye strains. Neon lamps were also not able to produce a focused beam like flashlights and produced an ugly yellow-green hue on video. Many lamps contain small amounts of mercury, which is now considered to be a biohazard. Lamps seemed to only serve a function of a purely decorational light with many…

The crystal structure of a material provides variety of important concepts on various scales. A proper understanding of the internal structure of the material through the characterization methods has become essential to identify the novel materials for a specific device application. Currently wide range of experimental methods is available to know the mechanical, chemical or electrical properties of the chosen materials. In this work, the prepared samples are studied using various techniques…

Galileo Galilei Galileo Galilei was an intelligent astronomer, physicist, engineer, philosopher, and mathematician who contributed to scientific revolution during the Italian Renaissance. He was born in Pisa, Italy on February 15, 1564. When he was 8 years old, he and his family moved to Florence in 1574 where he was educated in the Camaldolese Monastery at Vallombrosa. He had interests and focused on Science and Mathematics until he died. Galileo Galilei is a hero because he contributed to…

first light bulb, Sir Humphry Davy. Sir Humphry Davy was an English chemist who was responsible for illuminating an arc lamp by transferring electricity through a platinum wire in 1802…

Edison who, upon thinking about the light bulb decided that it would one day be possible to illuminate an entire city. The technology of creating light with electricity had existed since 1800 when Humphry Davis managed to create the first electric arc lamp by feeding electricity through carbon electrodes. While this did produce light, the system was extremely large and it burnt out quickly, resulting in a need to replenish the carbon electrodes frequently. The first improvement that was made on…
