What was Nikola Tesla contributions to society?

Answer 1

Tesla is often described as the most important scientist and inventor of the modern age. He is best known for many revolutionary contributions and inventions in the field of electricity and magnetism in the late 19th and early 20th centuries. Tesla's patents and theoretical work formed the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor, with which he helped usher in the Second Industrial Revolution.

After his demonstration of wireless communication (radio) in 1894 and after being the victor in the "War of Currents" ( in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by Westinghouse and Nikola Tesla.), he was widely respected as one of the greatest electrical engineers who worked in America. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. But due to his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist. Never having put much focus on his finances, Tesla died impoverished at the age of 86.

Aside from his work on electromagnetism and electromechanical engineering, Tesla has 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.

Many interpret the 1943 Supreme Court of the United States decision as crediting Tesla as being the inventor of the radio.

Nikola Tesla, at the 1893 World's Columbian Exposition in Chicago, demonstrated a device he constructed known as the "Egg of Columbus." It was used to demonstrate and explain the principles of the rotating magnetic field model and the induction motor. Tesla's Egg of Columbus performed the feat of Columbus with a copper egg in a rotating magnetic field. The egg spins on its major axis, standing on end due to gyroscopic action.

Tesla's device (two-phased induction motor) used a toroidal (doughnut shaped) iron core stator on which four coils were wound. The device was powered by a two-phase alternating current source (such as a variable speed alternator) to create the rotating magnetic field. The device operated on 25 to 300 hertz frequency. The ideal operating frequency was described as being between 35 to 40 hertz. Reproductions of the device are displayed at the Nikola Tesla Museum in Belgrade, the Technical Museum in Zagreb and in the Ann Arbor Hands-On Museum.
