A little story from a scientist! I can t wait for you to help! Thank you

Don't you know it at once?

Scientist Zhang Heng.

Zhang Heng, like his grandfather, has been studying hard since he was a child and is very literate. After the age of 16, he left his hometown and went abroad.

Study tours. He first went to Sanfu (now Xi'an, Shaanxi), the academic and cultural center at that time. This area is magnificent.

Mountains and rivers and the magnificent ruins of the ancient capital of the Qin and Han dynasties provided him with rich material for literary creation. Later, he came to the head of the Eastern Han Dynasty.

Duluoyang. There, he entered Taixue, the highest institution of learning at that time, and met a young scholar, Cui Ming, with whom he became close friends. Cui Ying was a student of Jia Kui, a scholar and astronomer at the time, and was also proficient in astronomy and calendar

Mathematics and other academic disciplines. In the twelfth year of Emperor Yongyuan (100 AD), Zhang Heng was invited by Nanyang Taishou Baode to be his.

The main bookkeeper is in charge of the paperwork. Eight years later, Bao De was transferred to Beijing, and Zhang Heng resigned at home. During his stay in Nanyang, he to.

He is committed to astronomy, yin and yang, calendar calculations and other knowledge, and repeatedly studies the "Taixuan Sutra" written by Yang Xiong of the Western Han Dynasty. He's in.

The fame of these aspects attracted the attention of Emperor An of Han. In the fifth year of Yongchu (111 AD), Zhang Heng was recruited into Beijing and worshiped as Langzhong.

In the first year of the Yuan Dynasty (114 AD), Shang Shulang was moved. The following year, he moved to Taishiling. Later, he was transferred to another position, but for 5 years.

Later, it was reverted to Taishi Ling. In total, he has held this position for 14 years, and many of Zhang Heng's major scientific research works are.

This is done in this phase. In the second year of Emperor Shun Yangjia (133 AD), he was promoted to the rank of servant. But soon by the eunuch platoon.

Squeezed and slandered, Yu Yonghe was transferred to Beijing in the first year (136 AD) and served as the prime minister of Liu Zheng, the king of Hejian. Liu Zheng is arrogant.

People who are extravagant and do not abide by the ** code, many local tyrants are lawless with him. After Zhang Heng took office, he strictly rectified the law and discipline, cracked down on Haoqiang, and made the top and bottom solemn. Three years later, he asked Emperor Shun to retire, but the imperial court worshipped him.

Chancery. This matter is quite strange, because Shangshu's official rank is far lower than that of Shizhong or Xiang, whether he applied for the job, history does not record.

In the same year (the fourth year of Yonghe, i.e., 139 A.D.), he died.

One day, the inventor Thomas Edison gave a light bulb to his assistant, Upton, a mathematics graduate at Princeton University, and asked him to calculate the volume of a glass light bulb. When Edison saw that he was sweating profusely, he said to him:"My God:

You should use this method to calculate! "He filled the bulb with water and handed it to Upton and said"Pour the water into a measuring cup and look at its volume, which is the volume of the bulb"When the assistant heard this, he suddenly realized, so he quickly calculated it according to the law.

When youngsters learn knowledge, they should combine book knowledge with practice, so that they can learn it lively, remember it, and apply it more easily. "

1 In 1921, the eighty-year-old French French Francis insisted on attending the grand celebration of the Nobel Prize in Literature. The celebration took place in the recital hall of the splendid Swedish Academy. During the dedication, Faldon sat at his table and "took a nap".

When he was asked why he was "napping", he explained: "No, I didn't doze off at that time, I just didn't understand Swedish, but I knew they were talking about me, and I hung my head to show my humility." ”

2 When the telegram of the Nobel Prize for Literature in 1965 arrived at Sholokhov, he was hunting in the forest on the outskirts, and later, when he went to Sdelmo to receive the prize in person, a large number of journalists came to interview him, saying that the Swedish Academy of Letters had belated the award to him twenty or thirty years later, and that he was in fact the first Soviet writer to actually win the prize. He also said: "On the day I learned that I had won the Nobel Prize in Literature, two guns were fired into the sky, and in addition to dropping two geese, I also unexpectedly dropped the Nobel Prize in Literature."

"Scientists Talk Science" Issue 7 The Story of Physics.

Once, when the Italian physicist Segre, who later discovered the antiproton, finished a report and Pauli and others left the conference room, Pauli said to him, "I have never heard such a bad report as yours." Segre didn't say a word.

Pauli thought for a moment, then turned back to the Swiss physical chemist Brescher, who was traveling with them, and said, "If you had made a report, it would have been even worse." Except, of course, for your last opening report in Zurich. ”

1, Hua Luogeng's patriotic story.

Hua Luogeng, a famous mathematician, was hired to give lectures in the United States in the same year, and was very respected by the academic community. At that time, the University of Illinois in the United States signed a tenured professor contract with him for an annual salary of $10,000. Hua Luogeng's life became comfortable all of a sudden, not only did he have a small western-style building, but the university also specially equipped him with four assistants and a typist.

After the founding of the People's Republic of China, some people always thought that Hua Luogeng had become famous in the United States and lived a prosperous life, and he would not come back. However, material, money, and status did not shackle his patriotism. Hua Luogeng resolutely gave up his treatment in the United States and broke through the blockade to return to his motherland.

While passing through Hong Kong, he wrote an "Open Letter to Students Studying in the United States", expressing his enthusiasm for dedicating himself to the motherland.

2. Li Siguang's patriotic story.

Li Siguang, a famous geologist, studied hard at the University of Birmingham for six years in the early years and obtained a master's degree in geology. His teacher, Professor Balton, advised him to stay and pursue his doctorate before returning to China.

Li Siguang declined the teacher's kindness, and he replied: No, I want to contribute the knowledge I have learned to my motherland as soon as possible. In 1920, he returned to China to work until the outbreak of the Anti-Japanese War. Later, he went abroad for a time and still insisted on the research of geology abroad.

At a time when New China was in ruins, he resolutely returned to China from Britain and made outstanding contributions to China's petroleum industry as the Minister of Geology of New China.

3, Qian Sanqiang's patriotic story.

Qian Sanqiang, the founder of China's atomic energy science industry, went to France to study atomic theory, and was considered by the Curie couple to be the best scientific researcher. In the year, Qian Sanqiang and his wife He Zehui proposed to return to China, and their mentors and colleagues repeatedly persuaded and retained them.

The Kuomintang ambassador to France viciously threatened: It would be strange if he could go to the shore of the mainland! This means very clearly. If Qian Sanqiang insisted on returning to the motherland, the Kuomintang spies would be poisoned halfway.

Regardless of his personal safety and life and death, Qian Sanqiang and his wife resolutely and wittily returned to the embrace of the motherland with their half-year-old daughter, making a major contribution to the development of China's atomic energy industry.

Anyang, okay, I'll tell you! Exactly 200 words Oh Georg Simon Oh was born in Erlangen, Germany, to a locksmith father. His father taught himself math and physics and taught him as a teenager, which aroused Ohm's interest in science.

At the age of 16 he entered the University of Erlangen to study mathematics, physics and philosophy, but due to financial difficulties, he dropped out of his studies and completed his doctorate in 1813. Ohm was a man of great genius and scientific ambition, he worked as a secondary school teacher for a long time, and the lack of materials and equipment caused many difficulties for his research work, but he persevered in scientific research in a lonely and difficult environment, making instruments by himself.
