Ask for the touching deeds of 3 physicists

Is there a specific reference? Or just three scientists?

Isaac Newton (1643-1727) was a great physicist, astronomer and mathematician, and the founder of the classical system of mechanics. Newton loved nature since he was a child, and liked to use his brain and hands. At the age of 8, he saved change to buy hammers and saws to make handicrafts, and he was particularly fond of carving dials, using the projection of small sticks on the disc to show the time.

He also made bicycles with pedals; I made a drip clock with a small wooden barrel; let go of a self-made kite with a small lantern (people thought it was a comet); A model of a mill was made using a mouse as a mouse, and so on. The most vivid example of his observation of nature was his first experiment at the age of 15: in order to calculate the wind force and speed, he chose to jump downwind and upwind during a strong wind, and then measured the distance difference between the two jumps.

When Newton was a student at Grantham High School, he lived at Clark Pharmacy in Grantham, where he developed a habit of scientific experimentation, which was a chemistry laboratory. In his notes, Newton categorized natural phenomena, including color schemes, clocks, astronomical problems, geometric problems, and so on. These flexible learning methods have laid a good foundation for his later creations.

Newton's great achievements are inseparable from his assiduity and diligence. His assistant HNewton said, "He seldom went to bed before two or three o'clock, and sometimes worked till the end."

Five, six. Spring and autumn are frequent.

Stay in the lab for five or six weeks until the experiment is completed. "He has a habit of persevering for a long time, concentrating on solving a problem thoroughly. He replied to people's questions about how he had the knack for seeing things

contemplation". This is precisely his main characteristic. There are many stories circulating about this:

When he was young, he used to lead a cow up the mountain while reading a book, only to find that he only had a rope in his hand when he got home. When reading, cook the eggs regularly, and as a result, boil the table and the eggs together in the pot; Once, when his friend had eaten a chicken and left a pile of bones on the plate, Newton remembered it, but when he saw the bones on the plate, he suddenly said, "I thought I hadn't eaten, but I had already eaten."

Through the above materials, I thought: What does Newton's learning method teach me? Learn from Newton's assiduous and industrious spirit.

Cheng Kaijia, a famous physicist, has the reputation of "China's nuclear commander" and has dedicated his life to the country.

Hu Gangfu is a Chinese physicist and educator. A native of Wuxi County, Jiangsu Province, he was born in Siyang County on March 24, 1892. In 1909, he entered Harvard University, graduated in 1913, and received a doctorate in philosophy in 1918.

** For X-Ray Studies:Experimental study of the X-ray critical absorption frequency of chemical elements

Experimental determination of the maximum velocity of photoelectrons in the X-ray frequency region". In the same year, he returned to China and served as a professor of physics and head of the physics department of Southeast University (before 1923, Nanjing Higher Normal School). In 1925, he became a professor at Jiaotong University.

In 1926, he founded the School of Science of Xiamen University and served as its dean. In 1927, he established the Fourth Sun Yat-sen University and served as the director of the Higher Education Division and the dean of the School of Science. In 1928, he assisted in the establishment of the Institute of Physics of the ** Research Institute and served as a full-time researcher, and later served as a special researcher of the Institute of Radium of the Peking Research Institute.

In 1931, he became a professor at Jiaotong University. In 1936, he was appointed dean of the College of Liberal Arts and Science at Zhejiang University. From 1918 to 1950, he was also a professor at Datong University, dean of the Polytechnic College, and president.

In addition, in 1946 and 1949, he went to Britain and the United States again and led a group of Chinese scholars to study microwave radar technology in the United Kingdom. After the founding of the People's Republic of China, he served as a professor at Tangshan Jiaotong University and Peiyang University, and in 1952 he was a professor at Nankai University until his death in Tianjin on March 26, 1966.

Hu Gang established the earliest physics laboratory in China at Nanjing Higher Normal School, putting Chinese physics teaching on the right track. Later, he first offered a modern physics course at Southeast University. In Zhejiang University, the School of Science has become one of the famous science schools among domestic universities. He has successively trained a large number of physicists in China, such as Wu Youxun, Yan Jici, Zhao Zhongyao, Qian Linzhao, etc. He was one of the founders of China's earliest non-governmental scientific academic society, the China Science Society, its monthly journal Science, and the Ming Library, and made achievements in China's development of modern science.

He was the formulator of China's modern system of weights and measures, and set the length unit of 1 foot 1 3 meters, the mass unit of 1 catty 1 2 kg, and the time unit of 1 second, which made the Chinese system of weights and measures have a simple conversion relationship with the International System of Units, and opened the way for China to adopt the metric system. He was the first to name a large number of physical terms such as potential and entropy. In 1963, he was elected as an honorary member of the Chinese Physical Society.

He is a patriotic science educator who loves the people and dedicates himself to science and democracy; In January 1932, at the critical moment of national peril, in Shanghai, he cooperated with the anti-Japanese army to severely damage the Japanese flagship "Izumo"; In 1938, he rejuvenated water in Taihe County, Jiangxi Province, and assisted Zhu Kezhen, president of Zhejiang University, to lead the school to move westward several times, and preserved the equipment and books. He is knowledgeable and has written a wide range of books, including more than 20 kinds of academic books, translations, special articles, and popular science books. He was loving, caring, and family-like, and praised by generations of his students.
