How did Nikola Tesla contribute to science?
In 1887, he constructed the initial brushless alternate-current induction motor. He demonstrated the brushless two-phase one-fifth horsepower (150 W) induction motor to the American Institute of Electrical Engineers (now IEEE) in 1888. Also in 1888, he developed the principles of his Tesla coil wich he patented it 1891.
In April 1887, Tesla began investigating what would later be called X-rays using his own devices as well as Crookes tubes. He did this by experimenting with high voltages and vacuum tubes. His technical publications indicate that he invented and developed a special single-electrode X-ray tube. Tesla's tubes differed from other X-ray tubes in that they had no target electrode.
At the 1893 World's Fair, the World Columbian Exposition, in Chicago, Illinois, celebrating the 400th anniversary of Christopher Columbus' first voyage to America, an international exposition was held, in which, for the first time, a building was devoted to electrical exhibits. It was a historic event and the beginning of a revolution as Tesla and Westinghouse introduced visitors to AC power by providing AC energy to illuminate the World Columbian Exposition. The public at large observed firsthand the qualities and abilities of AC power.
Some doubted that the system would generate enough electricity to power industry in Buffalo. Tesla was sure it would work, saying that Niagara Falls had the ability to power the entire eastern U.S. On November 16, 1896, the first transmission of electrical power between two cities was sent from Niagara Falls to industries in Buffalo from the first commercial two-phase power plants (known as hydroelectric generators) at the Edward Dean Adams Station. The hydroelectric generators were built by Westinghouse Electric Corporation from Tesla's AC system patent designs. Tesla's system designs alleviated the limitations of the previous DC methods. The nameplates on the generators bear Tesla's name. He also set the 60 hertz standard for North America. It took five years to complete the whole facility.
He was the genius that created:
Alternating-current power transmission
The Death Ray Machine
Polyphase alternating-current system
Rotating magnetic field principle
Tesla coil transformer
The light you use in your house, comes from alternate current which is the work of Nikola Tesla. The remote controls we use for toys or appliances comes from the work of Nikola Tesla and he contributed in varying degrees to the establishment of robotics, remote control, radar, and computer science, and to the expansion of ballistics, nuclear physics, and theoretical physics.
Milutin Tesla was his father and Djuka Mandic was his mother. Nikola Tesla did not have any children so his family tree ends there. Nikola Tesla has relatives still living who descend from his sisters and cousins. William H. Terbo is the closest living relative of Nikola Tesla and the youngest relative is a young woman named Danijela Tesla.
