When Chen Jiaer was still in middle school, the film Edison the Inventor was shown in Shanghai. One day, his father rushed to school to pick him up and go out to the movies. It rained heavily the day Madame Curie was released, but my father picked him up from school and went out to see a movie. After reading it, he said to Chen Jiaer, it would be great if you could make some discoveries like Madame Curie and make some great contributions to society. In this way, my father led Chen Jiaer to the road of science step by step.

Chen Jiaer remembers that when he was very young, his father always wrote alone in the study. One day, Chen Jiaer sneaked in, but it happened that there was a thunderstorm, and he suddenly cried. Father gave him a hug and asked why it thundered. Chen Jiaer said, I heard from my neighbor's grandmother that Raytheon's father wanted to split the unfilial people. My father said it was wrong. Lightning is the result of electric collision between yin and yang in clouds.

When my father was talking about static electricity, he also put a glass plate on two stacks of books, and asked Chen Jiaer's mother to cut some small paper figures and put them underneath, wrapped a building block with a piece of silk, and soon rubbed on the glass plate. Because of static electricity, those little paper men danced under the glass plate, which left a deep impression on Chen Jiaer.

For a while, there seemed to be a power outage in a place on the campus of Peking University. Chen Jiaer was very anxious when he learned that, so he ran to the transformer room to find his workmates and asked them to repair it. Asked who he was, he said, I'm Chen Jiaer. The workmate thought for a long time and said, Chen Jiaer? I don't know.

Just like a freshman at Peking University asking Vice President Ji Xianlin to look after his luggage. President Chen Jiaer's low-key and peaceful attitude towards others can be seen from this.

A reporter who interviewed Chen Jiaer said, "When I first met him, he had just finished a meeting of the foundation committee and was wearing an ordinary jacket. But at the beginning of our oral exam, although there was no camera, he put on a neat dark suit, which made me feel his respect for others. "

A student in Peking University once sent an email to Chen Jiaer, but the student didn't expect him to write back at all, because he had written to some teachers in Peking University before, but none of them wrote back. Those people's qualifications are far behind him, and he didn't write the letter seriously, so he asked a few questions and finally sent it out without wishing him a happy Spring Festival.

The next day, I opened my mailbox and my classmates received his reply. Chen Lao first welcomed the student to apply for his direction, then wished him to pass the exam, then answered his questions, and finally did not forget to express his New Year's wishes. Chen Jiaer:/kloc-After the European Renaissance in the 5th century, Newton integrated the achievements of Copernicus, Galileo and Kepler, established a complete theoretical system, established a rational thinking system to obtain a complete physical causal relationship by systematic experimental methods, and established a rational and scientific authority; Maxwell completed Maxwell's electromagnetic equations and established the classical field theory by summarizing the four laws of electromagnetism obtained from a large number of experiments. The concept of "field", which he established as the basic composition of material movement in nature, further developed people's concepts of matter and movement, and triggered the development of electrical engineering and the whole communication industry. Since the 20th century, the revolutionary development of physics, represented by relativity and quantum theory, has not only formed a new concept of time and space, movement and matter, but also greatly deepened human understanding of the basic laws of nature from micro to macro, promoted the development of the whole science and triggered a great leap in scientific and technological civilization. These scientists have always insisted on using the experimental methods of system science to understand the universe and the external world of human beings, from experiment to theory and then to guide practice. From them, they always embody the scientific spirit of seeking truth and being pragmatic.

Nevertheless, human understanding of nature is still very limited. All kinds of elements, microscopic particles and antiparticles that we human beings know only account for about 5% of the whole universe. More than 95% of the world is unknown to us, including dark matter that we can infer but don't know, accounting for about 23%; There is also dark energy, accounting for about 73%. After so many years of physical research, human beings still know very little, and there are too many things in nature waiting for human beings to explore. Chen Jiaer: Scientific spirit is the embodiment of human spiritual culture, including two aspects, one is scientific and cultural spirit, and the other is humanistic and cultural spirit. The former pursues truth, highlighting the spirit of exploring and revealing the basic laws of the objective world and pursuing objectivity and truth, while the latter pays more attention to perfection and beauty. Therefore, what science pursues is the unity of truth, goodness and beauty between human society and nature, that is, the harmonious development between man and nature and the construction of a harmonious and beautiful human society. Among them, the scientific spirit refers to the spirit of seeking truth and exploring truth only on the spot.

The continuous understanding of the unknown world and the development and progress of human society are all passed down from generation to generation by this scientific spirit. The Scientific Outlook on Development put forward by China emphasizes the respect for scientific laws and the coordinated development between man and nature, which embodies the scientific spirit of governing the country and seeking truth from facts.

For ordinary people, the essence of science is to scientifically understand nature, the world, respect scientific laws, master scientific methods, and establish a correct world outlook, outlook on life and values on this basis. How do you treat your work? Have you used scientific methods to explore objective laws in your work? Do you pursue the truth of life and the truth of the objective world, so as to realize a high-quality and high-quality life? Just as the scientific spirit can promote the progress of human society, this kind of diligent pursuit and pragmatic scientific spirit can promote the improvement of personal thought and the progress of career.

Scientific spirit is not confined to the field of scientists. It is a kind of human spirit, representing advanced culture and productivity. Chen Jiaer: Physics can be interpreted as the truth of everything in the world. It represents advanced culture and can be materialized into advanced productive forces. It can be said that our food, clothing, housing and transportation are inseparable from physics. For example, eating, microwave heating and radiation sterilization of the food we eat all use physical knowledge. Our TV, computer, mobile phone and other household appliances are inseparable from microelectronics physics, and the development of cars, trains and airplanes is also inseparable from the development of mechanics and thermodynamics. Many methods of diagnosis and treatment in modern medicine, such as X-ray, B-ultrasound, ct, nuclear magnetic resonance, γ-ray and laser scalpel, are also the results of direct application of modern physics.

In addition, without the establishment of quantum mechanics, there would be no solid-state electronic theory and semiconductor physics, and transistors and integrated circuits could not be created, so there would be no modern information technology, including the Internet, which we often use.

In a word, physics is a science to explore the basic laws of material composition and motion, and it is the foundation of modern natural science, as well as the foundation of the establishment and development of modern science and technology such as information, computer, atomic energy and laser. It can be said that it runs through all aspects of our lives.

In China, the word "physics" appeared in the pre-Qin period, but its meaning is much wider than today. Generally refers to human's rational understanding of nature and human itself. Ancient thinkers in China believed that the laws of nature and humanistic society are unified, and the laws of humanistic society should also be attributed to the laws of heaven and earth and nature. Later, some people summarized this view as "harmony between man and nature".

When we talk about creating a harmonious society, this kind of harmony includes two aspects: one is the harmony between man and nature; The second is the harmony between people. Physics studies the harmony between man and nature. And the harmony between man and nature will in turn affect the harmony between people. Our research on physics is that people should first understand the basic laws of nature, pursue truth, respect the laws, live in harmony with nature, and realize this unity between man and nature. This is also the connotation conveyed to people by the "Year of Physics".

In the long history of mankind, scientific culture and humanistic culture have always developed in interaction, and evolved in the direction of mutual intersection and integration, thus integrating into one, forming a brand-new spiritual culture. In this process, physics has a far-reaching impact on the development of human culture, which is helpful to stimulate the lofty spiritual realm of human beings and create a better material life. Father tells stories and knocks on the door of reading.

Chen Jiaer said that his father was born in a poor family with seven or eight brothers and sisters, and his grandfather was just an ordinary shop assistant and died young. In order to support the family, my father went to normal school after finishing primary school, and went to school while teaching. He likes telling stories in teaching. 17 years old, wrote and published the first book on students.

Chen Jiaer is an only child. In his memory, there are many books from his childhood, not only many fairy tales written by his father, but also literary books, various newspapers and magazines, pictorial and so on. His father writes and compiles books every day, and letters and manuscripts are often sent from home. In a family full of books, Chen Jiaer came into contact with picture books for the first time, which was a bit like comic books, thread-bound books and hardcover books. He could not bear to put them down in his hand. At that time, he was in primary school, but he was six or seven years old.

Father often tells him stories, starting from fairy tales, often in the middle. Stop and say, go and see for yourself. This became a stepping stone for Chen Jiaer to enter the door of reading. When you see something you don't understand, ask your mother. She is a piano teacher. By the third grade, I had been able to read and read newspapers independently, and even bound a Novel Monthly with only one author at that time.

● Read biographies of celebrities and establish an outlook on life.

My father's works, Miss Alice, Master Poirot, the son of the Hua family, and Children on the Fire Line, were deeply moved. 72-year-old Chen Jiaer is still fresh in my mind. Father's fairy tales advocate eliminating evil and promoting good, pursuing justice and peace and opposing oppression. It was because of his father's influence that Chen Jiaer initially decided to become a writer, and it was also his father who made him embark on the road of pursuing science.

My father likes math very much. He said more than once that he would continue to study if his family had money. At that time, we needed external strength and internal strength, and we needed science and technology to save the country. His father told him science stories, recommended some popular science books and took him to the movie Edison. He still remembers the scene when it rained heavily, and his father took him to see Madame Curie. After reading it, tell him that if he can be like Madame Curie in the future, this life will be worth it. After watching the movie, he found Madame Curie, a biography written by Madame Curie's daughter, and thought it was great.

The book that influenced him the most when he was a child was the great man Sun Yat-sen. According to the book, when Sun Yat-sen was a child, he asked his mother what the meaning of life was. Her mother replied, "Life is like a dream, and it slips away carelessly." Thus, Sun Yat-sen learned to "cherish time". This story deeply touched Chen Jiaer, a young man, and had a great influence on the initial establishment of his outlook on life and world.

After he 15 was admitted to the university, it was to resist US aggression and aid Korea. He read many patriotic books, such as Matro Soff, Zoya and Shula, which described the heroes of the Soviet Union's patriotic war. Matrosov, who blocked the enemy's loopholes with his chest, said that a person's existence is valuable only if he lets others live a better life. This made him gradually establish a belief that being a man must have a role and contribute to society.

● Reading must be guided.

"Books have accompanied my growth. When I have difficulties, I will find books to solve my difficulties. When I am unhappy, I read books to calm my mind. When I am free, I can read books, enjoy books and share other people's joys and sorrows. My career needs to read more books. "Chen Jiaer is still taking doctoral students, and usually spends more time reading professional books and documents.

He kept in mind Mr. Qian Sanqiang's words, "If a book is well read, it will become thinner and thinner", and the book will not "teach the book to death" until it returns to practice. Only in this way can the book become its own thing and improve itself step by step.

Chen Jiaer said: "Reading must have guidance, high taste and correct and scientific values. There are good books and bad books in the book. Some books look good. Although some books are good-looking, they may not be good for your outlook on life and values. "
