warped from the sinusoidal shape. So the main difference between AC and DC is the way the energy is transmitted. Why are we using Alternationg Current today? There are a few reason although mainly it was due to the technology of the late 1800's and early 1900's. Nikola Tesla being one of the leading scientists for Alternating Current, created a way to run engines and also convert AC Volts and Amps. He came up with this while he was supposedly in a park in Budhapest. He sat down and drew out the basic
Starting in the late 1700's, European engineers began tinkering with motor powered vehicles. Steam, combustion, and electrical motors had all been attempted by the mid 1800's. By the 1900's, it was uncertain which type of engine would power the automobile. At first, the electric car was the most popular, but at the time a battery did not exist that would allow a car to move with much speed or over a long distance. Even though some of the earlier speed records were set by electric cars, they did not

Rome and Pompeii which advertised travelers to go to a tavern situated in another town. In about the 1440's there was an invention of a movable-type of advertising which was a printing press.

To create a novel such as this, there are many concepts that must be strung together. Specifically for Native Son, the concepts were: the true nature of fiction, what it means to be black in America, and the challenge of writing the novel.
a struggling family underwent months of back breaking labor only to loose their house at the drop of a hat. It was a desperate and unmerciful time when an accidentally fractured ankle cost a man his job and his family food and shelter. In the early 1900's, strikes, riots, labor unions, and new political parties arose across the country.
