Students of physics majors in later generations must be very familiar with this man. He is one of the founders of modern mechanics and theoretical physics in China. In the future, he will also serve as the provost of Tsinghua University, the president of Peking University, and the vice president of the Chinese Academy of Sciences.
Seeing the doubts on the faces of Xu Zhimo and others, Zhou Peiyuan explained: "To put it simply, the earth has universal gravity, and the objects we throw will inevitably fall back to the ground. However, the greater the initial velocity of the objects thrown, the objects will fall
It has to be as far away as possible. When the air resistance is small enough and the speed is large enough, the object will never fall back to the ground. It will revolve around the earth and become a satellite orbiting the earth."
"Like the moon?" Lin Huiyin said in surprise.
Zhou Peiyuan nodded and said: "Yes, the moon is also a satellite of the earth. If humans can create an object that orbits the earth, then this object can become an artificial earth satellite. So I said this book is very interesting. The future technologies in the book seem
It’s so whimsical that it can actually be explained by scientific theories.”
Deng Shucun said with a smile: "In the past, airplanes and submarines were just imaginations in science fiction novels, but now they have become a reality? Let me tell you, literature is also one of the driving forces of science."
"Did Mr. Zhou come up with this artificial satellite theory?" Feng Wenbing asked curiously.
Zhou Peiyuan thought for a while and said: "To be precise, it was first proposed by Newton. Mr. Newton proposed a conjecture that when a cannonball is fired on a high mountain, the greater the speed of the cannonball, the farther it will fall. Since the earth is round, when the cannonball
When the speed reaches a certain level, the cannonball will not fall. This idea is called 'Newton's cannon'."
Xu Zhimo clapped his hands and praised: "Niu Weng is really a strange person! Can this artificial earth satellite really be manufactured?"
Zhou Peiyuan thought carefully: "It's difficult. The gravity of the sun and the moon, the gravity of the sun, and the resistance of the atmosphere are very complicated. The most important thing is how to give the artificial earth satellite a sufficient initial velocity. With the current science
The means are difficult to achieve.”
Today, Zhou Peiyuan is already conducting research on quantum mechanics. In a few years, he will go to the Princeton Institute for Advanced Study in the United States to engage in theoretical physics research, and participate in the general relativity seminar led by Einstein himself to work on the theory of relativistic gravity.
and cosmological studies.
Until the outbreak of the Anti-Japanese War, Zhou Peiyuan, adhering to his ambition of saving the country through science, resolutely changed his research direction to fluid mechanics, which was related to rockets and artificial satellites.
Zhou Peiyuan is very interested in the artificial satellites here, but unfortunately there are a lot of liberal arts and engineering students here, so they can't discuss science topics in depth with him.
Xu Zhimo and the others were still talking about literature here, and the political topic circle had already finished discussing the dispute between Ningxia and Guangdong. Chen Daisun suddenly asked: "I heard that Brother Meng He is planning to go to Europe recently?"
"We will leave next month," Tao Menghe said with a smile. "The World Socio-Economic Conference is held in The Hague, Netherlands, and I have been invited to attend."
Chen Daisun himself is an economist. He said with some envy: "Brother Meng He is still very influential. The World Social and Economic Conference even invited you. Are there any new research results?"
Tao Menghe said: "A survey report has just been completed, and the research object is China's industry and workers."
"Oh, brother Meng He, tell me quickly." Chen Daisun was very interested in this.
Tao Menghe recounted: "China's industrial development is very deformed. Workers are mostly concentrated in light industrial factories, mainly textiles, followed by mines and railways. In order to gain profits, capitalists employ a large number of female workers and child workers with relatively low wages. This kind of
This phenomenon is especially common in foreign-funded companies. The number of female workers is increasing very fast. Ten years ago, female workers only accounted for one-third of the number of workers in the country. This figure has now become 45.7%. Child labor has been used in the light industry sector, and
Toward the direction of younger workers, I visited six major cities for this survey, and the youngest child laborer was actually only 6 years old!"
Chen Daisun smiled bitterly and said: "Capitalists, for the sake of profit, they don't care whether there is child labor or not. This is true in Europe and America."
Tao Menghe added: "There are still some differences between China and the United States. The specific situation is even worse. The traditional bonded labor and apprenticeship systems have also continued into modern factories. Some poor lower-class families, in order to let their children learn the skills to make a living,
Take the initiative to be sent to a factory as an apprentice. Apprentices have to apprentice in the factory. At the beginning, they can only do odd jobs. They will not be paid for a year or several years. It is not until they are recognized by the factory and the master that they can start with a meager salary. There are even some cruel ones.
The master also withholds the apprentice's wages. This situation mainly occurs in Japanese-owned factories, and the Japanese call factory apprentices 'nurturing workers'."
When Xu Zhimo heard the topic discussed here, he immediately said angrily: "This is really unreasonable, the Japanese are too hateful!"
“What’s even more detestable is the indentured labor force,” Tao Menghe said. “The indentured labor force mainly appears in the mining and textile industries. Some mining companies all use indentured workers. Even in larger new mining companies, 27% to 77% are indentured workers.
Next is the cotton mill. The boss often sends people to the countryside to recruit workers, taking advantage of the ignorance of the villagers to exploit them. These bonded workers have no personal freedom at all, and the labor intensity is extremely high, but they can only get a meager salary and even live an inhumane life.
Living as a slave, being drained of every drop of blood from your body by the capitalists."
Tao Menghe's words made everyone dumbfounded. Jin Yuelin was surprised: "What is the difference between these bonded workers and the black slaves in the United States in the past?"
"There is still a difference," Tao Menghe said, "Black slaves are the private property of the slave owner, just like we raise chickens and cattle. We must take good care of them and not let the animals die easily. The treatment of bonded workers is much worse.
, they were coerced by force and had no choice but to work day and night in factories and mines. It was common for them to die from exhaustion, illness, or being beaten to death. Anyway, if one bonded worker died, ten more could be recruited."
Everyone listened in silence. Chinese bonded laborers were actually worse than American black slaves, but they were unable to change the bad status quo.

Just when Lin Huiyin opened a salon at home, the Chinese name of the book quickly became a hit in big cities in the north and south. The sales situation was many times better. After all, academic monographs have a narrow audience, while recreational love novels are aimed at the broad masses.
.
Especially those young girls, progressive young people and women with deep sorrows are particularly fond of this set, and more than 30,000 copies were sold in a few days.
Compared with the one currently being serialized by Zhang Henshui, it has a bit more of an exotic feel. It still describes a high-end luxury cruise trip. The love story between a rich girl and a poor boy is also something that I never tire of. It is normal that it is a bestseller.
Mao Dun also published a commentary article specifically for this in the journal of the Left Federation: "Mr. Zhou's work is not just that, we need to see the author's criticism of feudal ethics, the determination of the hero and heroine in pursuing love and freedom, and the determination of the hero and heroine in pursuing love and freedom.
Truth, goodness, and beauty in human nature. When disaster strikes, except for a small number of morally corrupt people, people leave their hope of life to women and children. This is a rare glory of human nature..."
Lu Xun did not specifically write a book review, but he also mentioned this book in his essays and gave a positive evaluation.
As for our Peking University beauty student Ma Jue, she has been reading it over and over all day long, admiring Mr. Zhou Da to the core.
