As recent events concerning oil spills in multiple locations have flooded the news, many people are wondering how oil drilling works and why something like an oil spill can happen. This article will attempt to answer these questions by explaining how the various processes of oil drilling work. What is an Oil Rig An oil …
A diopter is a lens that bends light in order to magnify an object. Diopters can be used to enlarge small objects or see across far distances and are generally integrated into other objects in order to maximize efficiency and accessibility. A diopter can also refer to a measurement that describes a lens’s optical power …
A common law enforcement practice known as "speed traps" or "speed trapping" is based on one universal factor: Almost everyone speeds. Everyone has their reasons but most people speed on occasion just because they can. While this excessive acceleration is usually harmless as drivers have enough time to slow down during emergencies, many fatal car …
Xenon is a noble gas–found all the way to the right on the periodic table of elements–that is odorless, colorless and heavy. It has many different uses, but one of the biggest uses that it has is the use in light bulbs. The reason for this is because when xenon is excited, it gives off …
Wireless power induction is already being used today in the form of electric toothbrushes. An electric toothbrush contains coils or loops in the toothbrush handle as well as in the base recharging unit. Because of their constant exposure to water, electric toothbrushes have to use inductive coupling as a means of recharging their batteries. Inductive …
How a wind turbine works depends on the type of wind turbine discussed. While most people think of windmills as being the only true type of wind turbine, this is simply not the case, as there are horizontal axis, vertical axis, and various other types of "special" wind turbines in service around the world. Horizontal …
Fiber optic lines, which can be as thin as a piece of human hair, are made of strands of glass that are optically pure. They are used to transmit light signals, and have the ability to carry these signals over long distances. How is Light Transmitted Through Fiber Optics? The process by which light is …
Known under the generic name of safe or safe box there is a very broad set of constructions. From simple home safes used to keep personal documents, to bank safes which include special building construction and security measures. All safes are sturdy constructions made of metal (most with different layers) and a removable part (or …
The fifth state of matter is actually the first phase of matter. It is called a Bose-Einstein Condensate. Matter in the fifth state is really slow moving and extremely condensed. It only exists at near absolute zero temperatures and is very fragile and unstable. It was discovered in 1995 by Eric Cornell and Carl Weiman through experimentation with rubidium, …
Cavitation happens when water moves at extremely high speed around an obstruction in its normal flow. This causes the water pressure around the propeller to drop, creating air bubbles which dissolve after a few moments and causing water to rush in on the empty space created previously by the bubbles then crashing against the obstruction. …
