The story of four scientists who died for science, 300 to 350 words, not much! thank you

Deng Jiaxian (1924— 1986) is a famous nuclear physicist in China and an academician of China Academy of Sciences. Deng Jiaxian was from Anhui and later worked as a physics teacher in Peking University. 1June, 1948, Deng Jiaxian went to the United States for postgraduate study,1June, 1950, and obtained a doctorate in physics. On the 9th day after he got his degree, he boarded the ship returning home. After returning home, Deng Jiaxian worked in nuclear theory in China. Deng Jiaxian is the main organizer and leader of China's nuclear weapons research and development, and is known as the "father of the two bombs". He has made great contributions to the research of atomic bombs and hydrogen bombs! 1956 gloriously joined the China * * * production party.

Deng Jiaxian has won the first prize of national natural science, the special prize of national scientific and technological progress and the title of national model worker.

Deng Jiaxian and Yang Zhenning are both from Anhui. They study in the same middle school. They played glass ball, squash and climbed trees together since childhood, and formed a deep friendship.

Deng Jiaxian led the basic theoretical research on detonation physics, fluid mechanics, equation of state, neutron transport and so on, completed the theoretical scheme of atomic bomb, and participated in guiding the detonation simulation test of nuclear test. After the success of the atomic bomb test, Deng Jiaxian organized forces to explore the design principles and selected technical approaches of the hydrogen bomb. He led and personally participated in the development and experiment of China's first hydrogen bomb in 1967.

A more critical person than God —— The story of Paulie

Austrian physicist Wolfgang Pauli was born in 1900 and died in 1958. He is a rare genius at the beginning of this century and has made outstanding contributions to relativity and quantum mechanics. Won the 1945 Nobel Prize in Physics for discovering the "incompatibility principle". This principle was discovered by him in 1924, which had a revolutionary influence on the establishment of atomic structure and the understanding of the micro-world.

Pauli wrote a summary paper on the theoretical and experimental results of general relativity at the age of 19. It was only three years before Einstein published his "General Theory of Relativity" (19 16). People thought that he was so young but had such original opinions, which shocked the whole physics circle and made him famous at one fell swoop.

There are many stories about Paulie. He is famous for his preciseness and erudition, and also for his sharpness and criticism. It is said that Pauli met Einstein at an international conference. After Einstein's speech, Pauli stood up and said, "I don't think Einstein is completely stupid."

Once, the Italian physicist segre, who later discovered antiprotons, finished his report and Pauli left the meeting room. Pauli said to him, "I have never heard such a bad report as yours." At that time, segre said nothing. Pauli thought for a moment, then turned to Brescher, a Swiss physical chemist who was traveling with them, and said, "If you give a report, the situation will be even worse. Of course, except for your opening remarks in Zurich last time. "

Another time Paulie wanted to go to a place, but she didn't know how to get there. A colleague told him. Later, this colleague asked him if he had found the place that day. Instead, he sarcastically said, "When you don't talk about physics, you should think clearly."

Paulie is rude to his students, too. Once a student wrote a paper for Paulie to read. Two days later, the student asked Paulie for advice. Paulie returned the paper to him and said, "Even mistakes are not enough."

But Pauli was called "the conscience of physics" by Bohr, because of his sensitivity and prudence, he had the ability to find mistakes at a glance. In physics, there is a "Pauli effect"-when Pauli appears, people there will make mistakes in both theoretical deduction and experimental operation.

And when Pauli says "Oh, there's nothing wrong with it", it usually means very high approval. There is a joke that Paulie went to see God after his death, and God showed him his own design plan for the world. Paulie shrugged after reading it and said, "You could have done better ..."

Running bell tower

There is an optician named Yang in Holland who is busy grinding lenses every day.

One day, naughty children went to the second floor to play with their polished lenses. A child folded two lenses to see things and shouted in surprise:

"It's strange, how did the bell tower come into being so far away?"

The children looked at each other in turn and cried in surprise.

Yang heard the children's shouts, ran upstairs, looked at the overlapping shots, and was suddenly shocked: it was clearly in the distant bell tower, how could it suddenly run over?

The children's unexpected discovery aroused Yang's interest in research. After constant research and improvement, he finally invented the telescope.

Feng Ru

-China's first aircraft designer.

Feng Ru, the designer of China No.1 Aircraft, was born in18831February 51May, and was born in Enping County, Guangdong Province. /kloc-when he was 0/2 years old, he was forced by life and went to San Francisco with his relatives to make a living.

1903, after learning that the Wright brothers invented the airplane, Feng Ru decided to rely on the strength of the people of China to build the airplane. Initiated by local overseas Chinese, the aircraft factory was established in Oakland, east of San Francisco in 1907, and Guangdong Aircraft Company was formally established in 1909, with Feng Ru as the chief engineer. That year the company began to make airplanes.

On September 2 1 65438,0909, at dusk, Feng Ru made its first test flight near a dome near Auckland, which was far away from residential areas. Besides the reporter, his three assistants were also present. After the plane took off, it flew 0.8km and turned 4.57m above the ground, when the propeller suddenly stopped, the plane fell to the ground and Feng Ru was thrown out of the plane. Fortunately, he was not hurt. The cause of the accident was that the screw of the propeller shaft was screwed too tightly, which caused the root of the propeller to break.

19 10 in July, Feng Ru made a second plane based on Curtis' golden arrow and Wright's Voyager 1. 10 From June to February, Feng Ru successfully made a test flight in Auckland, which was praised by Dr. Sun Yat-sen and overseas Chinese living in the United States, and won the A-class award from the American Institute of International Aviation. 19 1 1 In February, 2008, Feng Ru declined an appointment with many parties in the United States and returned home with his assistant and two planes. After the Revolution of 1911, Feng Ru was appointed flight captain by the Guangdong Revolutionary Military Government. 1965438+On August 25th, 2002, Feng Ru was killed in an air show in Tang Yan, Guangzhou, and was posthumously awarded as Major General of the Army. His body was buried in Huanghuagang and commemorated by a monument, and he was honored as "the first pilot in China".
