Nikola Tesla's (1856-1943) birthday, July 10th, is proclaimed by the United Nations - Nikola Tesla Day - a signify a day of science, cosmos explorations, and brotherhood among nations and religions around the world.
Nikola Tesla was born in Gospic, Croatia on July 9, 1856, and died January 7, 1943. He was the electrical engineer who invented the AC (alternating current) induction motor, which made the universal transmission and distribution of electricity possible. Tesla began his studies in physics and mathematics at Gratz Polytechnic, and then took philosophy at the University of Prague. He worked as an electrical engineer in Budapest, Hungary, and subsequently in France and Germany. In 1888 his discovery that a magnetic field could be made to rotate if two coils at right angles are supplied with AC current 90 degrees out of phase made possible the invention of the AC induction motor. The major advantage of this motor being its brushless operation, which many at the time believed impossible.
Tesla moved to the United States in 1884, where he worked for Thomas Edison who quickly became a rival - Edison being an advocate of the inferior DC power transmission system. During this time, Tesla was commissioned with the design of the AC generators installed at Niagara Falls. George Westinghouse purchased the patents to his induction motor, and made it the basis of the Westinghouse power system which still underlies the modern electrical power industry today.
He also did notable research on high-voltage electricity and wireless communication; at one point creating an earthquake which shook the ground for several miles around his New York laboratory. He also devised a system which anticipated world-wide wireless communications, fax machines, radar, radio-guided missiles and aircraft.
Many of the new technologies in the world today, are based on Tesla's ideas.
Tesla spent 50 years of his life to find a way for interplanetary communications, especially with Mars. He is the first scientist in the world to use the Ionosphere for scientific purposes (The Ionosphere is the upper part the atmosphere under constant bombardment of solar energy, which breaks down molecules into ions causing an ionized shield of our atmosphere, very important for radio communications).
