Some people will say Newton, others will say Einstein. ...

But the physicist who has made the greatest direct contribution to mankind must be Faraday! His achievements have changed human civilization forever!

As we all know, electricity has entered human life since the second industrial revolution. Until today, the whole human society is inseparable from electricity. No one can imagine how modern cities will function without electricity.

I can't imagine what human civilization would be like without Faraday.

At this time, some people will say that if there were no Faraday, other physicists would have invented the motor and generator. I doubt this view.

You know, Faraday invented the motor and its generator for ten years. There has been no progress in electromagnetism during this period, because Faraday was forced to burn glass during this period. At that time, many top physicists were studying this project, and no one had a realistic breakthrough like Faraday.

183 1 year1October 17 Faraday discovered the electromagnetic induction phenomenon as soon as he returned to electromagnetism, and then obtained the method of generating alternating current. Faraday invented the disk generator after 1 1 days.

What gift is this? This is a talent that even top physicists can't match! More importantly, this genius is also very diligent!

1839, he successfully conducted a series of experiments and led people to understand the nature of electricity. Faraday uses "static electricity", batteries and "biological power generation" to produce electrostatic attraction, electrolysis, magnetic force and other phenomena. From these experiments, he came to the conclusion that although the sources are different, the electricity generated is the same. This view laid the foundation for the future research direction of electricity.

In the later years of his career, he proposed that electromagnetic force not only exists in the conductor, but also extends to the space near the conductor. The idea was rejected by his colleagues, and Faraday did not live to see the idea accepted by the world after all. But time is gradually proving that Faraday is right.

Faraday also put forward the concept of electromagnetic wire, which helped the world visualize the abstract electromagnetic field and had a great influence on the development of electromechanical devices in the19th century. These devices dominated the whole engineering and industry in the19th century. 1845, he discovered what he named diamagnetism, which is still called Faraday effect.

Faraday introduced the important concepts of magnetic lines and wires into physics. By emphasizing the "field" between them instead of magnets, he opened the way for many Faraday exhibitions in contemporary physics, including Maxwell's equations. Faraday also found that if polarized light passes through a magnetic field, its polarization will change. This discovery is of special significance, indicating for the first time that there is a certain relationship between light and magnetism. This also provides an idea for Maxwell to predict that "light is electromagnetic wave". Maxwell also established the basic equation of electromagnetic theory according to Faraday's theory.

What is more commendable is that the father of electricity, who combines diligence and talent, loves and is pure in science. He does academic research without any purpose, and all fame and fortune are not important in his eyes.

Although he had a hard life, he refused the British government's reward fund. He was willing to fulfill his commitment to science as a civilian and rejected the nomination of the Royal Society to elect him as its chairman. For moral reasons, Faraday refused to participate in the manufacture of chemical weapons for the Crimean War. Even more amazing, he was born in poverty and refused the knighthood granted by the British royal family.

David has always been proud of being knighted, and likes to sign knighthood on his name everywhere. Faraday rejected the title of nobility. He will always be a civilian scientist who comes from and benefits the people. I won't be ashamed of not knowing that my teacher David has been informed in the spring.

Faraday's life is great, Faraday is ordinary. He is simple, unsociable and selfish, and likes to help relatives and friends. In order to concentrate on scientific research, he gave up all high-paying business jobs and worked in the laboratory of the Royal Academy of Sciences all his life, becoming an ordinary and immortal promoter of human civilization!
