Summary:
Explores the life and work of inventor Thomas Edison. Provides examples of his greatest inventions.
Thomas Edison was one of the greatest inventors and industrial leaders in history. Thomas Edison's inventions are still used today in many different ways. Although Thomas Edison received limited education and was mischievous, he made famous contributors to practical electric lighting and for inventions such as the Phonograph. Edison obtained 1,093 United States patents, the most the U.S. patent office has ever issued to one person.
One example of his inventions is the phonograph. In 1876 and 1877, Edison worked on improving experiments for recording and playing back messages sent over the telegraph and telephone, which led him to the invention of the phonograph. Later, he envisioned the phonograph being used as a dictating machine, and other people used his idea for selling musical recordings using the phonograph. Then, Edison began making his own recording. Therefore, his invention sparked a new era in home entertainment.
Thomas Edison began his important research on electric lighting in 1878. He made a device that produced an extremely bright light by sending electricity across a gap between two carbon terminals. Later, he modified his invention by passing electricity through a filament (wire) to make the filament glow. To make his invention practical Thomas Edison and his associates constructed electricity power plants to produce electricity needed for the electric lamps and lighting fixtures.
Although Thomas Edison did not invent the light bulb, but he made significant improvement. Nobody believed Thomas Edison, when he said he was going to make a light bulb, but his workers supported him and filled him with confidence. A quote given by Thomas Edison is:
"My main purpose in life is to make enough money to allow me to create ever more inventions.... The dove is my emblem.... I want to save and advance human life, not destroy it.... I am proud of the fact that I have never invented weapons to kill..."
By the fall of 1888, Edison envisioned a motion-picture device. He wrote
I am experimenting upon an instrument which does for the eye what the phonograph does for the ear."
In 1892, Edison left the electric light industry and phonograph, and his goal was to use technology to make the low-grade iron ore in the eastern United States viable. He built huge rock crushing machines and powerful electromagnetic to separate the iron ore from the rest of the rock.
Unfortunately, the best iron mines has already been exhausted, and his iron ore refining field proved to be his greatest commercial failure. Soon after abandoning the ore separating, Edison used his huge crushing machines to make concrete. In 1899, he created the Edison Portland cement company which was considered as one of his promotional skills.
Thomas Edison wasn't properly educated he was home-schooled. That didn't stop him from being one of the world's greatest inventors. He had done hands-on activities with his mom and got a very creative mind. Edison valued long and hard work. Throughout his practical career, he spent many long hours on his projects. With his saying genius is 1 percent inspiration and 99 percent perspiration," he encouraged all people to offer hard work. Thomas Edison received 1,093 united States patents, the most that has ever obtained by one person.
I think that Thomas Edison was a great inventor and scientist. His great inventions for the phonograph and electric light bulbs are worldwide symbols of bright ideas and great technical creativity.
