The first scientist to put forward the concept of nanometer.

Feynman is a descendant of Russian and Polish Jews who immigrated to the United States at the end of 19. Feynman diagram, Feynman rule and renormalization are put forward, which are indispensable tools for studying quantum electrodynamics and particle physics. He is regarded as the most intelligent theoretical physicist after Einstein and the first person to put forward the concept of nano.

My personal understanding of Feynman is when I pay attention to antimatter, especially in a popular science book. The appearance of antimatter was only Dirac's mathematical hypothesis, and people didn't believe it until antimatter particles such as antihydrogen atoms were actually created in the laboratory. But what really attracted me was richard feynman's antimatter conjecture and his unique mathematical way of studying physics.

Another point is that I didn't know the result until I searched the Internet this time. I still remember that it was 1986. People all over the world, including us, saw the disintegration of the American space shuttle "Challenge" and the picture of female teachers in the air. Later, many articles reported that a small rubber washer failed at low temperature, which led to tragedy. However, until today, the cause of the accident was confirmed by Feynman, a theoretical physicist who was not optimistic about the mass media.

1Feb. 988, suffering from cancer for ten years, and refusing treatment for the fourth recurrence. He doesn't want to live a life without quality. He said: "The last discovery I have studied in my life will be the situation of death. I knew this day would come when I was seven years old. There is no need to complain now. I think this experience must be very interesting. " This is what makes him different from ordinary people.

Feynman died and was buried in the Mountain View Cemetery in Pasadena. The tombstone simply says "Miss Feynman", and its epitaph is:

"Stop that now, Mr Feynman.
