Edison said: "Genius is 99% sweat plus 1% inspiration", and the latter part is "but that 1% inspiration is the most important, even more important than that 99% sweat".
Edison was the first person in human history to make use of a large number of production principles and electrical engineering research laboratories to patent inventions, which had a far-reaching impact on the world. His invention of the phonograph, movie camera and improved electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life.
19311018 died at 3: 24 am at his home in west orange, new jersey, USA, at the age of 84. Edison was named the ninth among the 65,438+000 people who influenced the United States by the authoritative American periodical Atlantic Monthly.
Extended data:
Contrary to popular understanding, Edison was not the inventor of electric light at first, but Edison improved it. As early as 180 1 year, a British chemist named humphry davy used platinum wire to electrify and glow in the laboratory. 18 10, he invented the "electric candle" which was illuminated by the arc between two charged carbon rods, which was the earliest prototype of the electric lamp.
Joseph swan, another British electrical engineer, after nearly 30 years' research, made a vacuum bulb with electricity and light from carbon wire in 1878+02.
The report about the swan's light bulb gave Edison a great inspiration. 1879 10, Edison finally succeeded in making an incandescent light bulb with carbon fiber as the filament, which is called "carbonized cotton filament incandescent lamp". Later, a large number of incandescent lamps were put into production, and companies were established to establish corresponding power stations, transmission networks and other infrastructure, which soon made electric lamps widely used in the United States.
During this period, he constantly improved his technology, and finally decided to use tungsten wire as the filament, which is called "tungsten lamp" and has been in use ever since, so Edison became a recognized inventor of electric lamp.
