The story of a scientist who forgets time at work.

One day, Einstein, a great scientist with a clear understanding of the world, went home, thinking while walking, and unconsciously walked through a strange place. When he found himself lost, he wanted to ask someone else, but he forgot his home address. Fortunately, he remembered the telephone number of his office and made a phone call to it. Afraid of his secretary's jokes, he pretended to be asked, "Excuse me, where does Einstein live?" Unable to recognize Einstein's voice, the secretary said, "Sorry, Dr. Einstein doesn't want to be disturbed. His home address can't be told." At this time, Einstein had to say, "I am Einstein." His words surprised the secretary.

If you have a guest at home, it must be impolite to ask him to sit down and let him stand. People will say you don't understand human feelings. However, Madame Curie, a world-famous physicist and chemist and two-time Nobel Prize winner, is such a "inhuman" person.

Madame Curie and her husband, Mr Curie, refused to socialize together in order to engage in scientific research. They often stay indoors for dozens of days. Sometimes they forget to cook and eat carrots to satisfy their hunger. Although the Curies are world-famous scientists, their families are very poor. One day, they received a letter from their father asking what furniture they wanted to buy.

Mr Curie said, "We only have two chairs. There is no place to sit when the guests come. Let's add another chair. "

Madame Curie said, "But as soon as they sat down, they didn't want to leave." So the two agreed not to add chairs in order not to let the guests occupy their own research time.

1946, the famous mathematician Hua was hired as a tenured professor by an American university with favorable conditions. But he replied: "in order to choose the truth, for the country and the nation, I want to return to China!" " Finally, he returned to Beiping (now Beijing) with his wife and children. After returning home, he not only devoted himself to theoretical research, but also traveled all over 23 provinces, municipalities and autonomous regions in China, and solved a large number of practical problems in production with mathematics, so he was known as the "people's mathematician".

In addition, famous geologist Li Siguang, biologist Tong Dizhou, nuclear physicist Qian Xuesen, high-energy physicist Zhang Wenyu and chemist Tang Aoqing ... all of them are full of patriotic enthusiasm and have made great contributions to the country's rejuvenation.

1949 People's Republic of China (PRC) was founded, which made Qian Xuesen extremely excited after staying in the United States for nearly 20 years. On the sixth day of the birth of New China, Qian Xuesen and his wife had a strong idea: to return to the lovely motherland and contribute their wisdom and strength to the new country. However, the road to return to China was full of twists and turns, which Qian Xuesen did not expect. When the science books and his research notes were packed by the American handling company and shipped back to China, they were made difficult by the US Immigration Bureau. They threatened the patriotic scholar in China in every way and put him in a detention center, which greatly restricted his personal freedom. For five years, he almost lived under house arrest. But hardships did not destroy the strong will of Qian Xuesen and his wife to return to the motherland. They packed the boxes. I am ready to fly back to China at any time every day. 1955, Qian Xuesen, who suffered a lot in anxious to return, called for help from his motherland, and the China government came forward to try to rescue him through negotiation. Finally, in September this year, Qian Xuesen and his wife returned to the embrace of the motherland after more than five years of struggle.

Watt was born in Greenock, England. Because his family is poor, he has no chance to go to school. He first worked as an apprentice in a watch shop, and then as an instrument repairman at Glasgow University. Watt is clever and studious. He often takes time to listen to professors' lectures. Plus, he fiddled with those musical instruments all day, so he accumulated a lot of knowledge.

1764, Glasgow University received a newcomen steam engine to be repaired, and the task was given to Watt. After the repair, we saw him working so hard, just like an old man panting and walking with a heavy load, and felt that it should be improved.

He noticed that the main problem was that every time the cylinder was heated by steam, it was cold and wasted a lot of heat. Can you keep the temperature low and the piston work as usual? So he rented a cellar at his own expense, collected several scrapped steam engines and decided to build a new machine.

From then on, Watt fiddled with these machines all day, and after two years, he finally took on a new look. However, during the pilot fire, the cylinder leaked everywhere, and Watt tried his best to wrap it with felt and tarpaulin. Months passed, but he still failed to solve the problem.

One day, he squatted in front of the cylinder to observe the cause of air leakage. He accidentally rushed out with hot air. He hurriedly dodged, and his right shoulder was red and swollen, as if he had been cut by a hot knife, which made him feel terrible. He's really depressed. At this time, his wife gave him courage, and his wife provoked his ambition to continue his research.

He went back to the underground laboratory, browsed the past data again, pulled himself together and went on working. When you are tired, let the stove boil a pot of water to drink tea. One day, while drinking tea, he looked at the moving lid of the pot. He looked at the pot on the stove and the cup in his hand, and suddenly he was inspired: the tea is getting cold, so pour it into the cup; If the steam is cold, why not pour it out of the cylinder?

In this way, Watt immediately designed a condenser separated from the cylinder, which tripled the thermal efficiency and used only a quarter of the original coal. When this key place was breached, Watt suddenly felt that the future was bright. He went to the university to ask Professor Black some theoretical questions, and the professor introduced him to Wilkin, the technician who invented the boring machine. Technicians immediately made the cylinder and piston by boring the barrel, which solved the most troublesome air leakage problem.

1784, Watt's steam engine was equipped with a crankshaft and a flywheel. The piston can be continuously driven by steam coming from both sides, and the valve does not need manual adjustment, so the world's first real steam engine was born.

Newton in his youth did not show outstanding scientific genius in his early years like Gauss and Wiener. Unlike Mozart, he showed amazing artistic talent. Like ordinary people, he spent his middle school days easily and happily.

If he is different from other children, it is that his hands-on ability is quite strong. Made a water clock that can measure accurate time; A linkage device of waterwheel and windmill is also made, so that the windmill can be driven by water when there is no wind.

/kloc-At the age of 0/5, a rare storm hit England. The wind roared, and Newton's house wobbled as if it were going to fall down. Newton was fascinated by the power of nature and couldn't help but want to test the power of hurricanes. He braved the storm and came to the backyard, running against the wind and jumping with the wind. In order to accept the stronger wind, he simply lifted his cloak and jumped up, determined the landing site, carefully measured the distance, and then.

16 1 year, Newton was admitted to Cambridge University. Although he was an excellent student in middle school, Cambridge University concentrated top students from all over the world and failed to catch up with others, especially in mathematics. But he was not discouraged, just as he liked to think when he was young, and he studied slowly until he understood it thoroughly.

In the first two years of college, he not only studied arithmetic, algebra and trigonometry, but also studied Euclid's Elements of Geometry, which made up for the shortcomings in the past. He also studied Descartes' geometry and mastered the coordinate method. These mathematical knowledge laid a solid foundation for Newton's later scientific research.

Four years later, he graduated from Cambridge University. /kloc-one day in 0/666, Newton invited his mother and brothers and sisters to his room. The room was dark, only a ray of sunlight shone through the small hole in the window, and a white light spot was reflected on the wall. Newton told them to pay attention to the light spot on the wall. He held a self-made prism in his hand and placed it at the entrance of the light to refract the light to the opposite wall. A magnificent ribbon suddenly appeared near the light spot. Like a rainbow in a clear sky after rain, this ribbon consists of seven colors: red, orange, yellow, green, cyan, blue and purple. Newton and his relatives watched the artificial reproduction of natural scenes. Later, Newton used a second prism to synthesize seven monochromatic lights into white light. He announced the birth of spectroscopy with white light decomposition experiment.

Newton explored the mystery of light and color, and at the same time, he also explored the mystery of gravity. He discovered the law of gravity from the fact that the apple fell from the tree, and mathematically demonstrated the law of gravity, establishing mechanics as a complete, rigorous and systematic discipline. On the basis of summarizing and summarizing the previous research results, through my own observation and experiment, I put forward the "three laws of motion". These three laws and the law of universal gravitation are isomorphic, forming the main pillars of magnificent mechanical buildings. This mechanical building is the base for the development of modern astronomy and mechanics, the base for the development of engineering technology such as machinery and architecture, and the base for mechanical materialism to rule the natural science field. A magnificent mechanical building was built.
