A Karnaugh map is a graphical method or shortcut that can be used to solve Boolean algebra problems. Boolean algebra is used to conduct computations and create expressions from two values. This type of math creates the basis behind much of computer science and modern circuit card design today. Maurice Karnaugh created the current version …
Hoverboards in movies are fictional, but there are actual hoverboards — though they are not the size of a skateboard. Hoverboards are simple contraptions that allow the user to travel without parts that would roll over the ground. Hoverboards are an offshoot of the hovercraft.

Sacrificial anodes are used in cathodic protection systems in order to protect the primary metallic component(s) from corrosion. A magnesium anode is a type of metal used on boats and ships in order to protect the vessel’s other metallic parts. It first protects the area’s less active metal and acts as a corrosion barrier. How …
For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices …
Room Temperature Vulcanizing (RTV) silicone is a rubber polymer used to create molds, prototypes, and sealant. It is extremely flexible and quite tear resistant. It is made up of two separate components: a base and a curative. RTV silicone can be poured, sprayed, brushed, or pumped onto a surface. Either moisture or heat dries it, …
