Who knows celebrity stories?

>＊Once, a reporter asked Kennedy: How did you become a hero during World War II? Kennedy replied: They sank my cruiser and I became famous. We know that Kennedy was aboard the DT-O No. 8 boat, which was sunk by the enemy, and he was injured as a result.

*Socrates’ wife was very fierce. Once, she lost her temper and scolded Socrates. Still angry, she took a large bucket of water and poured it on her. Mr. head. Socrates scratched his wet hair and laughed: After the thunder, there must be heavy rain. This is a natural law, and it also proves that this is the truth.

*Newton was very attentive in his studies. One day, his friends were treating him to dinner. During the dinner, he remembered a bottle of wine at home, so he told his friends to wait a moment while he went home to get the wine. This friend waited and waited, but did not see Newton coming back, so he had to go and see what happened. It turned out that Newton remembered an experiment on his way home. When he got home, he plunged into the laboratory and started doing the experiment, forgetting all about getting wine to entertain his friends. Another time, he was hungry and boiled eggs to eat, but while thinking about the problem, he put the eggs into the pot. When the problem was solved and he wanted to eat the eggs, he opened the lid of the pot and what he picked up was his pocket watch.

* Sima Guang of the Song Dynasty was born into a family of officials. He has been very resourceful and studious since childhood. He was admitted to Jinshi when he was just twenty years old. He was an honest official and often used time to read in his spare time, determined to write a general chronicle as a reference for people. In order to seize the time to study, he specially made a log pillow. The wonderful function of the pillow is that as long as the body turns over during sleep, it will roll, and the person will wake up and can continue to study knowledge, so it is called "alarm pillow". Whenever Sima Guang needed to rest, he would sleep on a "warning pillow". As a result of such study, he finally became a learned man

The story of Newton and Apple

For a long time Newton believed that there must be a mysterious force that pulls the planets in the solar system to revolve around the sun. But what kind of force is this?

Until one day, When Newton was thinking under the apple tree in the garden and an apple fell at his feet, Newton finally gained an epiphany and his problems were gradually solved.

. Hua Luogeng

In 1946, a certain university in the United States hired the famous mathematician Hua Luogeng as a tenured professor with favorable conditions. But he replied: "In order to choose the truth and for the sake of the country and the nation, I want to return to China!" Finally, he returned to Peiping (today's Beijing) with his wife and children. After returning to China, he not only devoted himself to theoretical research, but also traveled to 23 provinces, municipalities, and autonomous regions across the country, using mathematics to solve a large number of practical problems in production, and was known as the "people's mathematician."

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

2. The scientist has his homeland Pasteur

Pasteur was an outstanding French scientist in the 19th century and the founder of microbiology. He was famous for his invention of vaccination against infectious diseases. The law has made great contributions to the prevention and treatment of diseases for humans and livestock and poultry raised by humans. For outstanding achievements in science. As a result, he enjoyed a high reputation throughout Europe. The University of Bonn in Germany solemnly awarded an honorary degree certificate to this famous scholar. However, after the Franco-Prussian War broke out, Germany occupied French territory. Out of his deep feelings for his motherland and his great hatred for the invader Germany, Pasteur resolutely returned the honorary degree certificate to the University of Bonn. He said: "Although science has no national borders, scientists have their own motherland." These resounding words fully express the patriotic feelings of a scientist and have therefore become an immortal patriotic saying.

3. Qian Xuesen is devoted to the motherland

In 1949, the People’s Republic of China was founded. Qian Xuesen, who has been in the United States for nearly 20 years, was extremely excited. On the 6th day after the birth of New China, Qian Xuesen and his wife had a strong idea: to return to the lovely country of Dan and contribute their wisdom and strength to the newly born Republic of China.

But the road back to China was full of twists and turns and hardships, which Qian Xuesen had never expected. This scholar, who is "worth five divisions no matter where he goes," had already packed scientific books and his own research notes into boxes. When I handed it over to a U.S. moving company for shipment back to my country, I encountered difficulties from the U.S. Immigration Service. They intimidated this patriotic scholar in China in every possible way and put him in a detention center, where his personal freedom was extremely restricted. For five years, he almost lived under house arrest. But the many hardships did not dampen the strong will of Qian Xuesen and his wife to return to the motherland. They packed their boxes and were ready to take a flight back to the country at any time every day. In 1955, Qian Xuesen, who had suffered many hardships and was desperate to return home, issued a cry for help to his motherland. The Chinese government came forward to try to rescue him and return to the country through negotiations. Finally in September of this year, after more than five years of struggle, Qian Xuesen and his wife returned to the embrace of the motherland.

4. Boyle - Skeptical Chemist

Boyle Er attaches great importance to experimental research. He believed that only experiment and observation were the basis of scientific thinking. He always illustrated his views through rigorous and scientific experiments. In physics, he studied the color of light, vacuum and air elasticity, and summarized Boyle's gas law; in chemistry, he studied acids, bases and indicators, and qualitatively tested methods for salts. The discussions were quite fruitful. He was the first chemist to use the sap of various natural plants as indicators. He invented litmus solution and litmus paper. He was also the first chemist to clearly define acids and bases, and divided substances into three categories: acids, bases, and salts. He created many methods for qualitative testing of salts, such as testing copper salts by using the blue color of copper salt solution and adding ammonia solution to turn it into dark blue (copper ions form copper ammonia complex ions with sufficient ammonia water); using hydrochloric acid and nitric acid Mixing silver solutions can produce white precipitates to test silver salts and hydrochloric acid. Boyle's inventions have such a long-lasting vitality that we still often use these oldest methods today. Boyle also did many experiments in the determination of material composition and purity, and the study of material similarities and differences. In "A Brief Review of the History of Experimental Research on Mineral Waters" published in 1685, he described a set of methods for identifying substances and became a pioneer of qualitative analysis.

In 1670, Boyle suffered a stroke due to overwork. After that, his health fluctuated. When he was unable to conduct research in the laboratory, he devoted himself to organizing what he had gained from practice and reasoning over the years. Knowledge. As long as his body feels a little light, he can go to the laboratory to do his experiments or write papers and have fun doing so. In 1680, he was elected president of the Royal Society, but he declined the honor. Although he was born into a noble family, his lifelong passion was working and living in scientific research. He never married and devoted his life to the exploration of natural sciences. On December 30, 1691, this scientist who laid the foundation for chemical science in the 17th century died in London. Engels once made the most noble evaluation of him: "Boyle established chemistry as a science."
