What patriotic scientists are there in our country? Tell his story. Please, hurry up.

From 65438 to 0946, 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 returned to Peiping (now Beijing) with his wife and children. After returning home, he not only devoted himself to theoretical research, but also traveled to 23 provinces, municipalities and autonomous regions all over the country, and solved a large number of practical problems in production with mathematics, so he was known as the "people's mathematician".

In addition, there are 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.

This scientist has his native country Pasteur.

Pasteur was an outstanding scientist in France in the19th century and the founder of microbiology. Because he invented the method of vaccination against infectious diseases, he made great contributions to the disease prevention and control of human beings and livestock and poultry raised by human beings. Due to outstanding achievements in science. He enjoys a high reputation throughout Europe, and the University of Bonn in Germany solemnly awarded the honorary degree certificate to this famous scholar. However, after the Franco-Prussian War broke out, Germany occupied French territory. Out of deep affection for the motherland and deep hatred for the aggressor Germany, Pasteur resolutely returned the honorary degree certificate to Bonn University. He said: "Although science has no national boundaries, scientists have their own motherland." Hit the floor's words fully expressed a scientist's patriotic feelings, and thus became an immortal patriotic quote.

Qian Xuesen showed great love for his motherland.

People's Republic of China (PRC) was founded 1949. Qian Xuesen, who has been in the United States for nearly 20 years, is 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 motherland and contribute their wisdom and strength to the new country. However, the road to return home is full of twists and turns and hardships, which Qian Xuesen did not expect. This scholar, who is "worth five divisions wherever he goes", was made difficult by the US Immigration Bureau when he packed his scientific books and research notes and sent them to the US handling company for transportation back to China. 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. However, many hardships did not destroy the strong will of Qian Xuesen and his wife to return to the motherland. They packed their boxes and prepared to fly back to China at any time every day. 1955, Qian Xuesen, who was suffering 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.

4. Boyle skeptical chemist

Boyle attaches great importance to experimental research. He believes that only experiment and observation are the basis of scientific thinking. He always clarifies his views through rigorous and scientific experiments. In physics, he studied the color of light, the elasticity of vacuum and air, and summarized Boyle's gas law. In chemistry, his research on acid, alkali and indicator, and his discussion on the qualitative test method of salt are quite effective. He was the first chemist to use the juices of various natural plants as indicators. He invented litmus test solution and litmus test paper. He was also the first chemist to give a clear definition of acid and alkali, and divided substances into three categories: acid, alkali and salt. He created many qualitative methods to test salt, such as using copper salt solution to be blue, adding ammonia solution to become dark blue (copper ions and enough ammonia water form copper-ammonia complex ions) to test copper salt; The white precipitate produced by mixing hydrochloric acid and silver nitrate solution is used to test silver salt and hydrochloric acid. Boyle's invention is full of long-term vitality, so that we still often use these oldest methods today. Boyle has also done many experiments in determining the composition and purity of substances, and studying the similarities and differences of substances. A brief review of the history of mineral water experimental research published by 1685 describes a set of methods to identify substances and becomes a pioneer in qualitative analysis.

1670, Boyle suffered a stroke due to fatigue, and his physical condition was good and bad. When he can't do research in the laboratory, he devotes himself to sorting out the knowledge gained from practice and reasoning for many years. As long as he feels a little light, he goes to the laboratory to do his experiments or write papers for fun. 1680, he was elected president of the royal society, but he refused to accept this honor. Although he was born into a noble family, he devoted his life to scientific research and life. He never married and devoted his life to exploring natural science. 169 165438 On February 30th, the scientist who laid the foundation of chemical science in17th century died in London. Engels once gave him the highest evaluation: "Boyle identified chemistry as science."

5. priestley-the father of gas chemistry

1774, priestley put mercury soot (mercury oxide) into a glass dish and heated it with a condenser, and found that it quickly decomposed into gas. He thinks that the air has been released, so he collects the generated gas by gas collection and studies it. He found that the gas made the candle burn more brightly, and he felt relaxed and comfortable breathing. He made oxygen, and proved through experiments that oxygen has the properties of combustion-supporting and breathing. However, because he is a stubborn believer in phlogiston, he still thinks that air is a single gas, so he also calls this gas "dephosphorized air". The difference between its nature and the "air saturated with phlogiston" (nitrogen) discovered earlier is only the difference in phlogiston content, so its combustion-supporting ability is also different. In the same year, he visited Europe, exchanged many chemical views with lavoisier in Paris, and told lavoisier about the experiment of decomposing mercury and silver ash with condenser, which benefited lavoisier a lot. Lavoisier just repeated priestley's experiment about oxygen, and linked it with a large number of accurate experimental materials, made scientific analysis and judgment, and revealed the real connection between combustion and air. However, until 1783, when lavoisier's combustion oxidation theory was generally considered to be correct, priestley still refused to accept lavoisier's explanation, insisted on the wrong phlogiston theory, and wrote many articles against lavoisier's opinion. This is an interesting fact in the history of chemistry. A person who discovered oxygen became a person who opposed the theory of oxidation. However, priestley found that oxygen is an important factor in the vigorous development of chemistry. So chemists all over the world still respect Priestley.

179 1 year, he sympathized with the French revolution and made propaganda speeches for the revolution many times, but he was persecuted by some people, his home was copied, and books and experimental equipment were set on fire. He escaped alone and took refuge in London, but it was difficult for him to live in London for a long time. At the age of 6 1, he had to immigrate to the United States. Continue to engage in scientific research in the United States. 1804 is dead. People in Britain and America respect him very much, and England has a full-length statue of him. In the United States, the house where he lived has been built into a memorial hall, and the priestley Medal named after him has become the highest honor in American chemistry.

6. Madame Curie

Marie Curie (Madame Curie) was a French-born Polish physicist and chemist.

1906, pierre curie died in a car accident. This heavy blow did not make her give up her persistent pursuit. She fought back her grief and redoubled her efforts to complete their beloved scientific career. She continued her husband's lecture at the University of Paris and became the first female professor at the university. 19 10, her famous book on radioactivity was published. She cooperated with Mou and others to analyze pure metal radium and measure its properties. She also measured the half-lives of oxygen and other elements and published a series of articles on the importance of radioactivity.
