“If it has ‘science’ in its name, it ain’t (Minnick).” Those words were said to this writer by the smartest person he ever knew personally, a man with PhDs in Mathematics and Physics, a true scientist. He went on to explain that science, if it is science, can be reduced to mathematics and then can predict. “Science can generate electricity or flatten cities,” he said. The problem, of course, is that whenever one deals with the “soft sciences,” political science or economics (the dismal science) or sociology or history or any of the disciplines that are housed in ...

a) In bigger police headquarters wrongdoing scene examination is finished by a wrongdoing scene specialist, officers are first on scene responders and secure the wrongdoing scene, and they take notes in light of their quick discoveries.

Invented and patented by Thomas Edison in 1879, the incandescent bulb comprises of a wired filament placed inside a glass bulb (“The History”). When electricity is provided to the filament, it heats up thereby making the bulb glow and emit light (“Incandescent, LED”). The wired filament of the incandescent bulb was initially made using carbon obtained from a cotton thread that was uncoated. This filament gave the bulb a lifespan of just 14.5 hours. Later, the carbon filament was made using bamboo, which gave the bulb a longer lifespan of up to 1200 hours (“The History”). Much later, in ...

The purpose of this paper is to particularize the historical, science and technological impact of Li-Fi, to also include the vast reaching context of this incredible point in the wireless timeline. The paper seeks to establish the historic background of the Li-Fi technology as well as its technical working. The possibilities of Li-Fi extend to the application in military and undersurface communication operations. Traffic Management is another area where LED will be of great use. Li-Fi can be used in LED lights traffic managements. Other areas where Li-Fi will be ideal include disaster management, remote location positioning and dead ...
