Scientists' success stories

Thales is a businessman, but he is not good at doing business and making money. He is always exploring useless things, so he is poor and can't make money. He spent all his money when traveling, so some people say that philosophers are useless people, people who can't make money and people who are very poor. One year, Thales made a fortune with his knowledge. Of course, this statement may have the meaning of fabrication. He knew that there would be a bumper harvest of olives in Athens that year, and then rented out all the olive juicers in the village, so he took the opportunity to raise the monopoly price and made a profit. In order to prove that philosophers and wise men have more important things to do, he is more willing to pursue and make money. If he wants to make money, he is.

Astronomers who only care about the sky and don't look at their feet

One night Thales was walking in the wilderness, looking up at the starry sky, but he predicted that it would rain the next day. Just when he predicted that it would rain, his feet fell into a pit and he almost fell to death. Someone saved him. He said thank you for saving me, you know? It will rain tomorrow, so there is another joke about philosophers. A philosopher is a person who only knows what happens in the sky, but not what happens under his feet. But two thousand years later, the German philosopher Hegel said that a nation can only have hope if it has people who care about the sky. If a nation only cares about what is under its feet, it has no future. Thales was the first person to mark Greek wisdom.

A war was stopped by predicting a solar eclipse.

At that time, the kingdom of Medea and the Chaldeans in the lower reaches of the two river basins jointly captured Nineveh, the capital of Assyria, and the territory of Assyria was divided between the two countries. The Medes occupied most of today's Iran, and prepared to continue to expand westward, but they met with stubborn resistance from the Kingdom of Lydia. The two countries fought fiercely in the area along the Haruz River, and they didn't decide the outcome for five consecutive years. The war brought disaster to the people, and the people were displaced. Thales predicted that there would be a solar eclipse one day in advance. He threatened that God would fight against the world, and one day he would use the solar eclipse as a warning. At that time, nobody believed him. Later, as expected, on May 28th, 585 BC, when the soldiers of the two countries were in hand-to-hand combat, it suddenly became dark, and the day suddenly turned into night. The warring parties were terrified and immediately stopped fighting and made up. Later, the two countries also exchanged marriages. This event is recorded in the first volume of Herodotus's Persian War History. The end of the war, of course, has political and economic reasons, and the solar eclipse only played a "medicine" role.

This is a miracle that shocked the whole world: a mathematician who lives in a 6-square-meter hut borrowed a dim kerosene lamp, leaned against the bed board and consumed several sacks of draft paper with a pen, thus overcoming "1+2" in the world-famous mathematical puzzle "Goldbach conjecture" and creating a distance of "1+60". Chen Jingrun, a famous mathematician in China, created this miracle.

Two bombs

Westerners always find it incredible that China can develop "two bombs and one satellite" (atomic bomb, missile and satellite) in such a short time and with such poor quality. Before returning from visiting relatives in China, Yang Zhenning specially asked Deng Jiaxian, who did not disclose the nature of his work, and said, "It is reported in the United States that an American helped China develop an atomic bomb. Is this true? " After consulting Zhou Enlai, Deng Jiaxian wrote to tell him: "The atomic bomb and the hydrogen bomb were developed by China people themselves." Yang Zhenning shed tears with excitement after reading it. It is precisely because China has such a group of dedicated intellectuals that it has stood up a strong national backbone.

Hou, a chemist in China, is the founder of "Hou Shi soda process". Hou Yisheng made three great contributions to chemical technology. First, the secret of Sulweifa was revealed. Secondly, the China people's own caustic soda process-Hou's caustic soda process was established. Third, his contribution to the development of small chemical fertilizer industry. 192 1 year, after receiving his doctorate from Columbia university, he resolutely gave up his favorite tanning major and returned to the motherland with the great ambition of saving the country through industry.

Tianyou Zhan

Tianjin-Tangshan railway

From 65438 to 0888, Zhan Tianyou was recommended by his old classmate Mou to be an engineer in China Railway Company. Zhan Tianyou, which has been lost for seven years, has the opportunity to join the railway industry of the motherland. At this time, it was the construction of the Tianjin-Tangshan Railway. He didn't want to stay in Tianjin for a long time, so he went to the construction site to share joys and sorrows with the workers. As a result, it was completed and opened to traffic in only 80 days. However, Li Hongzhang played the role of the Englishman Jinda and promoted Jinda as the chief engineer. Zhan Tianyou's works were therefore copied.

Built the Luanhe River Bridge.

1890, the Qing government repaired the internal and external railways (now Beijing-Shenyang Railway), and Jinda was the chief engineer. 1892, the project goes to Luanhe Bridge, and many countries want to win this business. Of course, Jinda took the Englishman first, but the Englishman Cox failed because the bridge could not be built. Contractors from Japan and Germany also failed. As the delivery deadline approaches, Jinda has to ask Zhan Tianyou. Zhan Tianyou made a detailed analysis of the reasons for the failure of various countries, and made a thorough survey of the geological soil at the bottom of Luanhe River. Later, he decided to change the pile location, adopt the traditional method of China, dive into the bottom of the river with divers from China, cooperate with machine operation, successfully complete the piling task, and build the Luanhe River Bridge. This victory has strengthened the ambition of the people of China. 1894, the British Engineering Research Association elected Zhan Tianyou as a member of the Association. Since then, Zhan Tianyou has led the construction of the Beijing-Tianjin Railway and Pingyao Railway (Pingxiang to Liling).

Zhang was born in the third year of Emperor Jian, a shabby bureaucratic family in Shiqiao, E County, Nanyang County (now 50 miles north of Nanyang City, Henan Province). Grandfather Zhang Kan is a local official, who was once the prefect of Shu County and the prefect of Yuyang. When Zhang Heng was young, his family had declined, and sometimes he had to rely on relatives and friends for help. It was this poor life that enabled him to get in touch with the working people in the lower class and some production and life realities, which brought positive influence to his later scientific creation. In mathematics, geography, painting and literature, Zhang Heng showed extraordinary talent and extensive knowledge. Zhang Heng is one of the representatives of Huntian theory in the middle of Eastern Han Dynasty. He pointed out that the moon itself does not shine, and moonlight is actually a reflection of the sun's light; He also correctly explained the cause of the solar eclipse and realized the infinity of the universe and the relationship between the speed of planetary motion and the distance from the earth. Zhang Heng [1] observed and recorded 2,500 stars, created the world's first celestial globe with light leakage, the first instrument for detecting earthquakes-the seismograph for waiting for the wind, and also made a south guide car, an automatic drum car, a wooden bird flying to Wan Li and so on. Zhang Heng * * * is the author of 32 scientific, philosophical and literary works, among which astronomical works include Ling Xian and Ling Xian Tu. In order to commemorate Zhang Heng's achievements, people named a crater on the back of the moon as "Zhang Heng Crater" and the asteroid 1802 as "Zhang Hengxing". Guo Moruo, a famous writer and historian in China in the 20th century, commented on Zhang Heng: "Such an all-round development figure is rare in world history and admirable for thousands of years." Later people called Zhang Heng a wooden saint.
