I admire a scientist in China most, who wrote 300 words.

In history, many scientists have helped us to light up the night. Among them, Edison is the person I respect most. He had more than 2,000 inventions in his life, and 1328 inventions were patented. On average, there will be a new invention every 15 days. At the peak of invention, there is an invention every three days, so he is called "the king of invention", and his invention has made great contributions to mankind. He was curious when he was a child. No matter what happens, he will ask why. Whenever possible, he likes to do experiments easily, so he often makes big jokes. Once, he saw a hot air balloon flying and wondered if a person's stomach was full of gas. After that, he let his companion eat a powder that can produce gas, which almost killed him. His father also gave Edison a good beating, but his curiosity did not diminish. In class, he often asks questions that even the teacher can't answer. The teacher called him "idiot" and "imbecile", and finally he was expelled from school. But his mother is also a teacher and has been teaching him ever since. The most brilliant achievement in his life was the invention of the electric light. Before electric light appeared, people used dim kerosene lamps. He carefully studied a dazzling arc lamp and found 1600 kinds of heat-resistant metals and 6000 kinds of plant fibers, but all failed. Finally, one day Edison thought of trying cotton yarn, and then what they looked forward to day and night appeared in front of them: the light bulb gave off golden light. This day is 1879, 10, 2 1. Later, people designated this day as the invention day of electric light.

My most admired scientist-Madame Curie

Some people worship celebrities in pursuit of fashion, and this blind worship will also lead people astray; Some people respect celebrities in order to follow the example of their respected celebrities, learn from them and motivate themselves to serve the people like them. As people say, "the power of example is infinite." Many people have succeeded. Everyone has his favorite celebrity, and I am no exception. What I admire most is Madame Curie.

1898 65438+On February 26th, Madame Curie announced that she and her husband had discovered radium, and Marie Curie was the first woman to board the French Academy of Sciences. In the past three years, in order to extract pure radium, Madame Curie set up a pot in the yard and melted it one by one. However, the laser line is silently eroding her body, making her dizzy and weak, and her beautiful face is quietly fading away. She changed from a beautiful little girl, a dignified and determined female scholar, to a new term "radiation" in science textbooks, thus gaining a lot of property, but she regarded fame and fortune as dirt and devoted her life experience to her favorite scientific career. For the sake of science, she is getting weaker every day, at the expense of her appearance and even her body. I admire Mary's courage to devote herself to science.

If I were Madame Curie, I would protect my health first, and then I would finish my favorite scientific career. However, Marie Curie dedicated her beautiful appearance to the cause of science. Her beauty spans a hundred years, and her spirit of daring to devote herself to science spans a hundred years, which is exactly what we ordinary people should learn. Only by giving everything you have to the cause you love can your life be valuable.

Let's follow the example of this great woman and be a person of value to society.

The scientist I admire most-Qian Xuesen

Grandpa Qian Xuesen is a famous scientist in China, who has made outstanding contributions to the establishment and development of the rocket, missile and space industry in the motherland, and is an advocate of system engineering theory and applied research in China. 19 1 1 Born in Shanghai, 1934 graduated from Shanghai Jiaotong University. In order to serve the motherland better, he was admitted to MIT for further study on 1935, and transferred to California Institute of Technology for further study on 1936, where he studied aviation engineering theory under the famous aviation scientist von Carmen. Grandpa Qian Xuesen studied very hard. After three years, he got a doctor's degree and stayed in school to teach. Under the guidance of his teacher, he became interested in rocket technology. Soon, Grandpa Qian Xuesen became the youngest tenured professor at California Institute of Technology.

From 1935 to 1950, Grandpa Qian Xuesen made great academic achievements and paid well all his life, but he always missed his motherland. 1949 When the first five-star red flag was slowly raised in Tiananmen Square, Grandpa Qian Xuesen was deeply happy for the rebirth of the motherland. He intends to return to China and use his professional knowledge to serve the new China. However, it was not easy for China scientists in the United States to return to China at that time, and grandpa Qian Xuesen's professional knowledge was directly related to national defense, so he went through all the hardships and finally returned to his motherland after 20 years' absence with the help of Premier Zhou Enlai. His tortuous struggle process shows Grandpa Qian Xuesen's deep love for the motherland. How touching!

1In the early winter of 955, Grandpa Qian Xuesen, who had just returned to the motherland, visited Harbin Institute of Military Engineering. Dean General Chen Geng asked him: "Can China people engage in missiles?" He said, "If foreigners can do it, why can't China people do it? Are China people shorter than foreigners? ! What a strong national pride and self-confidence! " This sentence decided his career in rocket, missile and space. 1956 the first missile research institute in China was established, with grandpa Qian Xuesen as the first president.

At Jiuquan launch site, Grandpa Qian Xuesen slept in a tent and ate coarse grains, and organized the test, calculation, analysis and research of missile tests. Under his guidance, China scientists overcame many difficulties and successfully conducted the flight test of China's first missile on June 5, 1960+065438. 1966, 10/0 On October 27th, Grandpa Qian Xuesen participated in the flight explosion test of China's first medium-short range surface-to-surface missile with a nuclear warhead, that is, the "two-bomb combination" test of atoms and missiles. The successful explosion of a nuclear warhead over a predetermined location shocked the world. An American general said that no matter where Grandpa Qian Xuesen was, it was equal to the fighting capacity of five divisions.

Grandpa Qian Xuesen made some achievements abroad, but he didn't forget his motherland. After the founding of New China, he gave up his superior living conditions, broke through the obstacles of the United States, and finally returned to his motherland, devoting all his talents to the development of national defense and cutting-edge science and technology in China. How admirable this spirit is! Students, today we are primary school students. In ten years, we will graduate from the university. At that time, the heavy responsibility of rejuvenating the country will fall on our shoulders. How worthy of our study is the deeds of Grandpa Qian Xuesen!
