Tesla gave up the patent right.

Many outstanding scientists have emerged in modern times, such as Einstein and Hawking. Some of these scientists are often called "the closest human being to God", and this person is the "unknown" nikola tesla. Perhaps, many people may feel strange when they see this name, but if you get to know nikola tesla, a science geek, you will find that this science geek really deserves the title of "the person closest to God". Then, he was called "the person closest to God", and 1 1 times declined the Nobel Prize. Why haven't you read the textbook about him?

Among many inventions, the most surprising is the alternating current system invented by Tesla. Although the direct current invented by Edison made electrical appliances widely used, it brought many benefits to people until Tesla invented the alternating current system. The electricity bill was greatly reduced, and eventually alternating current replaced direct current and became the mainstream of society at that time. At that time, Tesla had a patent for alternating current, which would make him the richest man in the world. But what is rare and valuable is that Tesla directly gave up the patent right to give up alternating current and made the patent public permanently, benefiting the whole world. So Tesla lost the opportunity to become the richest man in the world, but gained the respect of the world.

Because Tesla has made many great contributions to mankind, in just over 20 years, Tesla has been nominated for 1 1 Nobel Prize. Everyone knows that the Nobel Prize is the prize that scientists all over the world dream of, but Tesla still carries forward the character of not pursuing fame and profit, does not accept the prize and refuses all eleven Nobel Prizes. Moreover, no one in the world knows why Tesla refused to win the Nobel Prize, probably because he no longer needs to use the Nobel Prize to prove himself, because his contribution to mankind is great enough.

Tesla's contribution to mankind is not only here, but also can be seen.
