The scientist I admire most - Edison

In history, there have been many scientists who have benefited us mankind and made the night light up. Among them, Edison is the one I respect the most. He is the most famous person. He has made more than 2,000 inventions in his life, and has obtained 1,328 invention patents. On average, a new invention is invented every 15 days. During the peak period of invention, there was an invention every two days. He was therefore known as the "King of Inventions". His inventions made significant contributions to mankind. He was extremely curious as a child. He always asks why everything happens, and he likes to experiment whenever possible, often making big jokes about it. Once he saw a hot air balloon flying and wondered if it would fly if a person's stomach was full of gas. He made his companions take a powder that produced gas. As a result, he almost died. His father was also cruel. Edison was beaten hard, but his curiosity did not diminish. In class, he often asked questions that even the teacher couldn't answer. The teacher called him "idiot" and "imbecile", and was eventually expelled from the school. However, his mother was also a teacher, and she was his mother from then on. Teaching him. The most glorious achievement in his life was the invention of the electric light. Before the advent of electric lights, people used dim kerosene lamps. After carefully studying a dazzling arc light, he searched for more than 1,600 heat-resistant metals and 6,000 plant fibers, but all failed. Finally one day Edison thought of trying it with cotton yarn, and then the scene they had been looking forward to day and night appeared in front of them: the light bulb gave off a golden light. This day was October 21, 1879. Later, people designated this day as the invention day of the electric light.

The scientist I admire most - Marie Curie

Some people worship celebrities for the pursuit of fashion, but this blind worship can also lead people astray; some people worship celebrities , in order to use the celebrities they admire as role models, learn from them, and inspire themselves to serve the people like them. As they say: "The power of example is infinite." So many of these people succeeded. Everyone has their favorite celebrity, and I am no exception. The one I admire the most is Marie Curie.

On December 26, 1898, Marie Curie announced on the podium of the French Academy of Sciences that she and her husband had discovered radium. Marie Curie was the first woman to attend the French Academy of Sciences. In the past three years, in order to refine pure radium, Madame Curie set up a pot in the yard and smelted pot after pot. However, the radium rays were silently eroding her body, making her become Her ears were ringing, her eyes were dizzy, and her whole body was weak. Her beautiful appearance was quietly fading away. She changed from a beautiful little girl, a dignified and resolute female scholar, to a new term "radiation" in science textbooks, and thus gained a large amount of property. However, she regarded fame and wealth as dirt and devoted her life's experience to I started my favorite scientific career. For the sake of science, she did not hesitate to lose her appearance and even her body was getting weaker day by day. I admire Mary's courage to dedicate herself to science.

If I were Marie Curie, I would definitely protect my own health first, and then complete my favorite scientific career. However, Marie Curie gave her beautiful appearance to the scientific career. Her beauty Her spirit of daring to devote herself to science has spanned a century. This is what we ordinary people need to learn from. Only by dedicating everything to the cause you love can your life be valuable.

Let us follow the example of this great woman and be a valuable person to society.

My most admired scientist - Qian Xuesen

Grandpa Qian Xuesen is a famous scientist in my country. He has made outstanding contributions to the creation and development of the country's rocket, missile and aerospace industry. He is a key figure in my country's system engineering An advocate of theoretical and applied research. He was born in Shanghai in 1911 and graduated from Shanghai Jiao Tong University in 1934. In order to better serve the motherland, he was admitted to the Massachusetts Institute of Technology in the United States for further study in 1935. In 1936, he transferred to the California Institute of Technology to continue his studies. He became a disciple of the famous aeronautical scientist von Kármán and studied aeronautical engineering theory.

Grandpa Qian Xuesen studied very hard. After three years, he obtained a doctorate and stayed at the school to teach. Under the guidance of his teacher, he developed a strong interest in rocket technology. Soon, Grandpa Qian Xuesen became the youngest tenured professor at Caltech.

In the 15 years from 1935 to 1950, Grandpa Qian Xuesen made great academic achievements and enjoyed generous benefits in life, but he always missed his motherland. When the first five-star red flag slowly rose in Tiananmen Square in 1949, Grandpa Qian Xuesen was deeply happy for the new life of the motherland. He plans to return to China and use his expertise to serve New China. But it was not easy for Chinese scientists in the United States to return home at that time, and Grandpa Qian Xuesen's expertise was directly related to national defense, so he went through all kinds of hardships, and finally with the help of Premier Zhou Enlai, he finally returned to his motherland after 20 years of absence. His tortuous struggle process shows Grandpa Qian Xuesen's deep love for the motherland. How touching it is!

In the early winter of 1955, Grandpa Qian Xuesen, who had just returned to his motherland, came to visit the Harbin Military Engineering Institute. The dean, General Chen Geng, asked him: "Can the Chinese develop missiles?" He said: "Foreigners can do it, why can't the Chinese do it? Are the Chinese shorter than foreigners?! This is such a strong national self-esteem and Self-confidence!" This sentence determined his career in rockets, missiles and aerospace. In 1956, my country's first missile research institute was established, and Grandpa Qian Xuesen was appointed as the first director.

At the Jiuquan launch site, Grandpa Qian Xuesen, like ordinary scientific and technical personnel, slept in tents, ate coarse grains, and organized the testing, calculation, analysis, and research of missile tests. Under his guidance, Chinese scientists overcame many difficulties and successfully conducted my country's first missile flight test on November 5, 1960. "On October 27, 1966, Grandpa Qian Xuesen participated in organizing the flight explosion test of my country's first medium- and short-range surface-to-surface missile equipped with a nuclear warhead, that is, the "two-bomb combination" test of an atom and a missile. The nuclear warhead was successfully carried out over the predetermined location. A nuclear explosion shocked the world. An American general said that no matter where he was, Grandpa Qian Xuesen was worthy of the combat effectiveness of five divisions.

Grandpa Qian Xuesen has achieved great results abroad, but he has not. He never forgot 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 intelligence and wisdom to the development of our country's national defense and cutting-edge science and technology. How admirable! Classmates, today we are primary school students. Ten years from now, we will graduate from college. At that time, the important task of revitalizing the country will fall on our shoulders. Grandpa Qian Xuesen’s deeds are so worthy of our study!

It took me a long time to hope for adoption
