Nikola Tesla (1856-1943), born on July 10, 1856, is a world-renowned inventor, physicist, mechanical engineer and electrical engineer. Of Serbian descent, he was born in Croatia (later incorporated into the Austrian Empire). Tesla is considered an important inventor in history. He made outstanding contributions to electricity and magnetism in the late 19th and early 20th centuries. His patents and theoretical work on modern alternating current electrical (AC) systems, including polyphase power distribution systems and AC motors, helped usher in the Second Industrial Revolution.
Evaluation
“The scientific community generally believes that there are two unique geniuses in human history, one is Leonardo Di Ser Piero Da Vinci (Leonardo Di Ser Piero Da Vinci), The other is Nikola Tesla.”
In the United States, Tesla’s reputation in history or popular culture rivals that of any other inventor or scientist. After he demonstrated wireless communication in 1893 and became the winner of the Battle of the Electric Currents, he became highly respected as one of America's greatest electrical engineers. Many of his early results became precursors to modern electronic engineering, and many of his discoveries were groundbreaking and important. In 1943, the U.S. Supreme Court recognized him as the inventor of radio. Tesla’s legacy can be seen everywhere in the modern world of electricity. In addition to his achievements in electromagnetics and engineering,
Tesla is also considered to have contributed to various fields such as robotics, ballistics, information science, nuclear physics, and theoretical physics. In his later years, Tesla was regarded as a mad scientist and was noted for his claims to create bizarre scientific inventions. Many of his achievements have been used with some controversy to support many pseudosciences, such as UFO theory and New Age occult theory. Tesla's contemporary admirers regard him as "the man who created the twentieth century." He is a great man forgotten by the world. He invented the alternator, and Edison loved the DC generator he invented, so he worked with some companies to suppress Tesla. If Tesla had not been forced to give up the patent rights of alternating current for the world to use for free ($2.53 per horsepower), he would be the richest man in the world. His dream is to provide the world with inexhaustible energy. Tesla never cared about his financial situation and died poor and forgotten at the age of 86. Although he was a genius, it is a pity that not many people remember him.
