As the popularity of locomotives spread The first working electric light was invented in 1802 by Humphry Davy “In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp” (http://www.bulbs.com/learning/history.aspx) Thomas Edison finally perfected electric lighting creating the light bulb we know today. Edison and his team spent more than two years and three thousand variations perfecting the light bulb eventually settling on a glass bulb container holding low pressure inert gasses. On the inside a loop of super thin tungsten wire filament came from the neck of the bulb. A strong electric current was then run through the wire eliminating it as it became white hot producing light. Dynamite was invented in 1867 by Alfred Nobel. Dynamite is an explosive composed of nitroglycerin mixed with silica. The silica stabilizes the nitroglycerin before detonation and turns the liquid into a malleable paste.…
