In fact, the relationship between Tesla and AC is that he improved a high-frequency AC motor instead of inventing AC. As long as there is magnetoelectricity, it is a natural process to generate alternating current. If you have to find a father of alternating current, the father of alternating current can only be Faraday. As for the Tunguska Big Bang, it is even more ridiculous. The Tunguska Big Bang released hundreds or even a thousand times as much energy as the Hiroshima atomic bomb. At that time, the total power resources in the world were not so much.
The reason why Tesla was blown so badly is inseparable from CCTV's platform. CCTV once broadcast a documentary about Tesla. Although the content is absurd, many people are scared by CCTV's signboard, and Tesla has become a myth.
Since the 1990s, there has been a wave of craze for Tesla on the Internet, which was first published in the unofficial media of the former Soviet Union. After numerous self-media advocacy and amplification, it gradually spread to the whole world. A tragic life with outstanding achievements but suppressed from the bottom is often more attractive and caters to the spread of conspiracy theories. Tesla is so popular. Later, it even developed to claim that Tesla triggered the Tunguska Big Bang and invented long-distance power transmission, particle beam weapons, consciousness cameras and X-rays. Of course, these are all nonsense.
When we comment on a scientist, we should have enough knowledge of his research field and content, which is both a respect for the scientist himself and a respect for science. Study more and make less big news.
