He also won the 1965 Nobel Prize in Physics for his research in quantum electrodynamics. If you want to know Feynman's magic and interests, the best way is to read this book. In the process of reading this book, I laugh a few times from time to time, or learn one or two life experiences from the book, or learn some souls.
But most importantly, I realized the extraordinary pleasure of exploring a great man.
I remember when I was in college, my classmates joked about advanced mathematics. There is a big tree with many people hanging on it. Especially calculus, which is difficult to learn in advanced mathematics, is a nightmare for freshmen.
Feynman read the Encyclopedia Britannica when 13 years old. Knowing that calculus is very important and interesting, he decided to study calculus. When Practical Calculus was put on the shelves, he excitedly went to the library to borrow it. The librarian saw Feynman, a junior high school student, and said, "Why do you still borrow this book when you are such a big child?" That's for adults! "
So, he lied and said that he borrowed it from his father, but he wanted to see it. Finally, I took the book home and began to teach myself calculus. He also explained calculus to his father. From the book Practical Calculus, he never thought that his father would find calculus difficult to understand.
This also made Feynman sad: he didn't know that his father actually had something he couldn't learn. But he thinks those are simple and clear, clear at a glance.
During World War II, Hitler of Germany ordered Heisenberg to develop an atomic bomb. It would be terrible if it was developed before the United States. Therefore, during the war, all scientific projects in the United States were stopped, except the Manhattan Project hosted by Oppenheimer. The Manhattan project is to separate uranium isotopes, with the ultimate goal of making bombs.
However, the isotope of uranium originally separated was not the same as that needed in the end, so a meeting was held in the meantime. What impressed Feynman most was that everyone at this meeting could put forward different opinions from different angles. However, everyone can remember what others say, listen attentively to what others say, and finally sum up-there is no need to repeat their own views.
Everyone is the smartest person. This is really a scam, you know? One advantage of working with smart people is that you don't have to consider everyone's self-esteem. This is too shocking for Feynman. Everyone is really amazing.
In the Manhattan Project, mathematician Bette came to Feynman's office to work. Bette said on her first day here, "Let's look and calculate the pressure"? -"The pressure of 48, the square of 48 is ..." When Feynman reached for the calculator, Bette had already said, "The calculation result is 2304."
Feynman asked him how he worked it out. Betty said, "Don't you know how to calculate the square of 50?" For example, if a number is next to 50, then 47 is 3 smaller than 50 and 22 is 3 smaller than 25. "Then the square of 47 is that the first two digits are 22 and the last two digits are the square of the difference between the two numbers." "For example, 47 is 50 minus 3, and the square of 3 is 9, so the square of 47 is 2209. Wonderful, isn't it? "
Betty is really good at math. She is proficient in all algorithms, such as calculating 2? Cube root, he immediately reported: 1.35. Betty said, "You know that the logarithm of 2.5 is XX; You divide by 3 to get the cube root of XX. " "So, the logarithm of 1.3 is this, and the logarithm of 1.4 is XX, so I will take a value between the two."
In the following decades, Feynman and Bette often competed who could calculate faster. Feynman can beat Bette almost every four games.
In the Manhattan Project, the place where the atomic bomb was made was on the Gobi Desert in New Mexico. Feynman's residence is a dormitory for two people. They told Feynman that only two people can live in a room now. But Feynman's wife is being treated in the hospital outside, and he doesn't want to share a room with others.
He opened his wife's suitcase, took out one of her little pajamas and threw it on the upper berth, making it look like someone had slept in it. He took out her slippers again and sprinkled some makeup powder on the bathroom floor. He wanted others to think that there was a woman in this room besides him, which lasted for four nights. Finally, the house belongs to him alone.
When the scientist who developed the atomic bomb finished the calculation, the next thing to do was of course the nuclear test.
Feynman is 20 miles from the center of the nuclear explosion. He knows nothing about what happened next. The military distributed sunglasses to the observing scientists, but after wearing them, they could not see anything. Feynman thought that only ultraviolet rays hurt eyes. He hid in the car, so ultraviolet rays couldn't penetrate the windshield. So he is "safe" and can see what he wants to see.
It is time. There was a huge flash, so dazzling. I saw the white light gradually turn yellow and then orange. An orange mushroom cloud appeared in the sky. Feynman became the only one who looked directly at the scene of the explosion with the naked eye.
After World War II, Feynman went to the library to write a report. He needed a document. Those materials are kept in the library of Los Alomos, and there is a huge knob on the security door, which has a unique style. Feynman thinks that one of his colleagues works in a secret office and backs up data in nine filing cabinets.
So he found his old colleague's office and found the door open, but no one was there. As he waited, he naturally got used to it. While waiting, he quickly turned over the password disk on the filing cabinet. He tried 10-20-30, and it didn't work; 20-40-60, still not working. All the combinations have been tried, but it still doesn't work, so he has to wait bored.
Suddenly, it occurred to him that a locksmith could unlock a lock by guessing people's psychology. He will try to use psychological knowledge to unlock the lock. Rule number one, people will write down their passwords somewhere. So he immediately opened the drawer and read the note inside. Found a π, 3. 14 1527.
He immediately pulled up the password disk, 3 1-4 1-52. The filing cabinet was opened with a bang.
During the Manhattan Project, Feynman met niels bohr and Agel Bohr. Niels bohr won the 1922 Nobel Prize in Physics for his research on atomic structure and atomic radiation. Agger Bohr won the 1975 Nobel Prize in Physics with Ben Mottleson and James for his theory of nuclear structure. Both father and son are very famous physicists. For other physicists, Bohr is simply a god.
On one occasion, Feynman and other physicists attended a conference held by Bohr. There were many people at the meeting, and Feynman sat in the back corner. Throughout the process, Bohr can only be seen behind the dense spoons.
That morning, Feynman got a call from Bohr and invited him to the technical area to discuss the atomic bomb. Feynman and Bohr are discussing repeatedly, but Feynman only has physics in his eyes. If he thinks an idea is bad, just say it. They discussed for about two hours and discussed many ideas back and forth. You come and go, and you argue for a long time. The great Bohr kept lighting his pipe and mumbling, but Feynman knew better what his son Agger was saying.
Finally, Bohr, the great god of physics, said, "Well, you can call the big shots in." So Bohr called everyone together to discuss.
Later, his son told me this: "The last time we met, Bohr said to his son," Do you remember the name of the little guy sitting in the back? He is the only one who is not afraid of me. If there is anything wrong, he will say it directly. Therefore, the next time we want to discuss it, we can't tell others first. They'll just say, yes, yes, sir, that's right. But let's find that guy first. Let's talk to him first. "
It is such an old man with infinite enthusiasm for science that makes the boring scientific research life interesting. What I see in him is self-confidence, optimism, fun, curiosity, dare to question, imagination, independent thinking and awe of authority. These are all valuable qualities that each of us can learn from Feynman and can also teach the next generation.
