What contribution did Nicholas Terra make to mankind?

Nikola tesla (1856- 1943), born in July 1856, is a world-famous inventor, physicist, mechanical engineer and electrical engineer. He was born in Croatia (later incorporated into the Austrian Empire) and is of Serbian descent. Tesla is considered as an important inventor in history. He made outstanding contributions to electricity and magnetism at the end of 19 and the beginning of the 20th century. His patents and theoretical work forms are based on modern AC systems, including multiphase distribution systems and AC motors, which helped him bring about the second industrial revolution. "The scientific community generally believes that Leonardo da Vinci and nikola tesla are two prodigies in human history." In the United States, Tesla's reputation in history or popular culture can rival that of any other inventor or scientist. After he demonstrated wireless communication in 1893 and became the winner of the current war, he became one of the greatest electronic engineers in the United States and was highly respected. Many of his early achievements became pioneers of modern electronic engineering, and many of his discoveries were groundbreaking and important. In A.D. 1943, the United States Supreme Court recognized him as the inventor of radio. In the modern world where electricity is used, Tesla's legacy can be seen everywhere. In addition to its achievements in electromagnetism and engineering, Tesla is also considered to have made contributions in robotics, ballistics, information science, nuclear physics and theoretical physics. Tesla was regarded as a mad scientist in his later years, and attracted attention because he claimed that he could create weird scientific inventions. Many of his achievements are applied with some controversies to support many pseudosciences, such as UFO theory and mysterious theory in the new century. Contemporary admirers of Tesla regarded 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 and tried his best to suppress Tesla. Tesla would be the richest man in the world if it hadn't been forced to give up the patent for free use of alternating current ($2.53 per horsepower). His dream is to provide inexhaustible energy for the world. Tesla never cared about his financial situation and died of poverty and forgetfulness at the age of 86. Although he is a peerless genius, unfortunately not many people remember him. During the period of 1888, many newspapers reported that Thomas Edison, a famous inventor, declared that nikola tesla was a "heresy" in the scientific field. His invention of alternating current (AC) directly affected the safety of human life, and showed many times how dogs and cats died instantly after AC (the "electric chair" death penalty was also inspired-it is said that Edison. But alternating current doesn't kill people. It electrocuted all prisoners. But in fact, today everyone knows how much the world needs alternating current. The invention of alternating current improved people's life, promoted the development of industry and promoted the progress of science. But why did Edison attack alternating current and its inventor Tesla again and again? The answer is that the emergence of alternating current directly threatens Edison's DC business. Because using DC has too many disadvantages and limitations. For example, DC is not conducive to long-distance transmission, and power stations will be added every 1 km, but alternating current can be transformed by transformers as long-distance transmission; The use of direct current is more expensive and its efficiency is far less than that of alternating current. Based on the conflict of interest, Edison tried his best to suppress Tesla's invention. Prior to this, Tesla invented 24 new designs for the great scientist Edison, including the design of DC generator, which was patented by Edison and mass-produced. However, his efforts were rewarded with ruthless deception and ridicule. Tesla got angry and left Edison and his company. This is the prelude to the current war in history. 1888, with the support of Geovge Westing House, an entrepreneur of Westinghouse Electric Company, Tesla developed a communication system that had been conceived for six years. Six months later, the alternator he developed was patented, and he was invited by the American Institute of Electrical Engineers to explain and demonstrate the research results of the AC system. Because the efficiency of alternating current is far superior to that of direct current, alternating current is widely used and gradually replaces traditional direct current. Driven by interests, Edison vigorously attacked Tesla and branded it as a "scientific heresy", which led to a scientific persecution. Although alternating current has become the mainstream of industrial and social power supply and the necessity of our daily life, the name nikola tesla has been forgotten or even rehabilitated. This is a masterpiece of orthodox science.
