Although Sun Yuanqi was very busy, before Christmas in 1899, he still managed to find time to visit Lord Ding Hailiang and Minister Kangge.
Ding Hailiang is as kind as ever and as nagging as ever. When he met Sun Yuanqi, he complained that he had not come to visit him for so long, and also complained about the management of the Capital University. Amidst the complaints and complaints, Sun Yuanqi felt the kindness and kindness of the old man. The old man tried his best to persuade Sun Yuanqi to have lunch with him. When saying goodbye, he also told me to come often in the future.
As for Minister Kanger, meeting him is just a hug. After shaking hands, Mrs. Conger said with a smile: "We received a letter from Tomy, in which he highly praised your outstanding achievements."
Mr. Conger patted Sun Yuanqi on the shoulder: "You have been living like a hermit for more than a year, so you can achieve such excellent results. You must know that after you became famous, many people were asking who York Johnson was. , this is a topic that diplomats love to talk about. Although no one knows the answer better than us, we have always kept silent. Keeping secrets is my ethics, whether as a soldier or a diplomat."
Sun Yuanqi thanked him repeatedly.
When the Lunar New Year was about to arrive, Sun Yuanqi¡¯s paper was finally completed. The paper was called ¡°On the Electrodynamics of Moving Bodies and the Relationship between Mass and Energy.¡± The paper is divided into three parts:
The first part is the kinematics part, which first takes the principle of relativity and the principle of the invariance of the speed of light as the basic postulates and starting point. Starting from two basic principles, the famous Lorentz transformation equation is derived. At the same time, he also derived the "length contraction" of a moving rigid body, the "time dilation" effect of a moving clock, and the "addition theorem" of speed, closely connecting space and time with material motion, and revealing the relativity of space and time.
The second part is to apply the derived Lorentz transformation equations to electrodynamics, believing that the electromagnetic field equations have the same form in different inertial systems. Therefore, "the idea of ??only light ether as a carrier of electric and magnetic forces no longer fits the theory proposed here", that is, the ether does not exist. In the article, the asymmetry problem caused by applying the classic Maxwell equations to Faraday's electromagnetic induction experiment was also solved, and the Doppler principle and the theory of light aberration were discussed.
The third part is to derive the famous mass-energy equation e=mc2, which unifies the law of conservation of mass with the principles of energy conversion and conservation. This is the theoretical basis that led to nuclear weapons such as atomic bombs and hydrogen bombs. In the article, an experimental plan was designed to demonstrate using ¦Â-rays emitted by radium-bromide particles.
Although it sounds simple, when it is actually put on paper, it requires rigorous derivation and rigorous proof. Therefore, the paper is very lengthy, but fortunately it does not exceed the previous "Photoelectric Effect: From Phenomenon to Essence". Before the Spring Festival came, I sent it to "science" as a New Year gift. Nowadays, "Science", which is so popular in later generations, has become Sun Yuanqi's back garden, and he can publish articles almost whenever he wants.
Then, the Spring Festival came.
The Spring Festival is the most important festival for Chinese people, so all the students in the school have had a holiday. Gu Zhilin, Chen Jide and Liu Bin were all from Zhili and were the first to return. Han Qu, Zhou Zongwu, and Zhang Chun lived in Beijing, and on the 28th of the twelfth lunar month, they all came to Sun Yuanqi's yard to hang out. As for the primary school, Tong Jingren, Tong Jingzhi, Tong Jingsheng and the "Five Young Masters of the Sun Family" "each go back to their own homes and find their own mothers." The yard suddenly became quite vacant.
The old man seemed to be his own steward, and he directed the two busy east of Lao Zhao and Lao Zheng. Sun Yuanqi saved a lot from his salary this year, enough to have a good year. Perhaps it was because of the New Year or because of his pride, Lao Tong was so happy that he drank.
Early in the morning on the first day of the Lunar New Year, Lao Tong led two other families to Sun Yuanqi¡¯s residence to pay New Year greetings. They knelt on the ground, large and small. Sun Yuanqi quickly asked everyone to get up. Everyone has lucky money. Seeing that five or six children can all recognize a few words, the melancholy in my heart is relieved: I came here, after all, I changed the fate of some people!
After the first day of the Lunar New Year, we began to go from house to house to pay New Year greetings. It had been a year and a half since Sun Yuan had been in the Qing Dynasty. Because he had been writing books behind closed doors, he didn't know a few people. I think they were Mr. Sun Jianai, Mr. Ding Weiliang, and Minister Kangge. The others were gone. The two foreigners were just going through the motions; Mr. Sun Jia Nai visited Mr. Sun Jia Nai once a year ago, and if he goes there again now, he might be so packed with visitors that he won¡¯t even be able to get there on the fifteenth day of the first lunar month!
On the second day of the Lunar New Year, Lao Tong went back, probably to his brother's place. Lao Zheng's family also went out to visit. Lao Zhao's family came here to escape famine and had no relatives or friends in the capital. In this way, the old Zhao family was preparing lunch with Zhao Jinghui and Song Jingyao. Old Zhao, as well as two boys, Zhao Jingxing and Zhao Jingfan, chatted with Sun Yuanqi wordlessly.
At this time"" Sun Yuan started.
Mr. Shi laughed loudly: "Hahaha, Mr. Baixi, this is no problem! What about the fourth one?"
"Fourth there is no fourth point." Sun Yuanqi's third point was all thought of temporarily, so naturally there is no fourth point.
"Okay! Mr. Baixi is really a scholar!" Mr. Shi hugged his fists at Sun Yuanqi, and then said, "As for the remuneration issue, I can't give you a definite figure now, but you can rest assured that our library will never owe you anything!"
Sun Yuanqi waved his hands, indicating that he could trust them. So Mr. Shi and Mr. Yin began to pack up all kinds of textbooks on the table, intending to take them away in one go.
When he was waiting to go out, Sun Yuanqi glanced at the thickest dictionary and said in surprise: "Why, you still took the dictionary?"
"Can't we take the dictionary?" Mr. Shi was a little frightened when he saw Sun Yuanqi's surprised expression.
"No, no!" Sun Yuanqi quickly explained: "The key is that it's useless for you to use a dictionary!"
"Primary school Chinese textbooks have Pinyin. But with Pinyin alone and no dictionary, Pinyin is useless!" said the young man named Yin.
When Sun Yuanqi thought about it, it was the same reason. I just let them take it away, and just asked them to get it back as soon as possible. After all, this is the "only one in the country". There is only one in the world and no other branches! (Remember the website address: www.hlnovel.com
