And what about the Dutch side?

A few months ago, Li Kangping made two copies of "The Principle of Electron Spin and Incompatibility", one to Einstein and the other to Lorenz.

Lorenz's letter was replied late, and his letter had just arrived in New York.

"Dear Lee: I must tell you that the amount of work to be done in the argument of the Electron Spin and Incompatibility Principle is too great for an old man like me, and the amount of computation in it is even greater than that of the Atlantic! Fortunately, Mr. Ehrenfest and his students Uhlenbeck and Gosmit helped me with some of the calculations. ”

"I prefer to believe that the young man Uhlenbeck is a mathematician with an amazing talent for mathematical calculations. After more than a month of working day and night, Uhlenbeck calculated that if an electron rotated around its own axis, its surface velocity would reach ten times the speed of light! ”

"This result seems ridiculous in terms of our current level of intelligence and the amount of knowledge we have, and it makes Uhlenbeck extremely frustrated. Professor Ehrenfest comforted Uhlenbeck with this, hey, kid, you're young, it's not a big deal to do something stupid. ”

"So, Lee, please tell me, what are the calculations that you didn't write in your paper? Is it also ten times the speed of light? ”

Leiden University is the national team of the Netherlands, and the Leiden School can represent the entire Dutch academic community. Under the organization of Lorenz, the leader of the Leiden School, the Dutch side also took action.

Li Kangping wrote back to Einstein and Lorenz, answering all kinds of doubts about the "electron spin and incompatibility principle" of these two physics leaders.

Sending a letter, Li Kangping went to Queens.

Today is an important day, Li Chong's wife and son have come to the United States.

Li Kangping met his sister-in-law and nephew at Li Chong's house.

The sister-in-law's name is Zhu Yunzhen, she wears a slender dark dress, her hair is cut short, and her appearance is dignified and playful.

The nephew's name is Li Bingsheng, and he wears a children's dress, and his hair is smeared with pomade, neatly combed to the side.

"Sister Yun Zhen, Ah Bing, your safe arrival is the best news."

"Kangping, I miss you very much."

"Uncle Kangping, I miss you too!"

The aunt invited by the family prepared the meal, and Li Kangping had dinner with Li Chong's family of three.

Li Kangping's father had two friends, one surnamed Cai and the other surnamed Zhu.

At the beginning, Li Kangping wanted to open a mahjong factory in the United States, but there was a shortage of funds, so Li's father asked Cai and Zhu to borrow 70,000 oceans and exchange them for US dollars to be remitted to Li Kangping.

Is Zhu Yun really Uncle Zhu's daughter? He is 26 years old.

Is China's marriage about the right family? Li and Zhu were both merchants in Guangzhou, and the parents of the two families agreed to marry in early 1914? Arrange for Li Chong to marry Zhu Yunzhen? In July of the same year, Li Chong and Zhu Yunzhen got married.

Zhu Yunzhen gave birth to Li Bingsheng in 1915? Since then, he has been teaching his husband and children in his in-law's house.

Li Chong is the righteous son of Li's father, but Li's father regards Li Chong as his own son? Therefore, Li Bingsheng is equivalent to the eldest grandson of the Li family.

Send the eldest grandson Li Bingsheng to the United States? Mr. Li did not agree to do so.

The relevant personnel did a lot of ideological work on the old man, and the old man approved the release.

Li Bingsheng studied private school at the age of four, learning the Three Character Classic, the Hundred Family Names, the Analects, and Mencius. He entered Guangzhou No. 1 Primary School at the age of six, and he is eight years old this year? Before going to the United States, he was a second-year student at a primary school in Guangzhou.

Li Chong went to the United States at the end of 1921? He and his wife and children have not seen each other for two years, and this time they are happy, happy and warm.

In the next few days, Li Chong took his wife and son to visit New York? Li Kangping didn't bother, so that their family of three enjoyed themselves.

A family of three is almost playing? Li Kangping discussed the private affairs of the Li family with Li Chong alone.

"Ah Ping is of the right school age, and Ah Bing's studies in the United States should be arranged." Li Kangping suggested.

What does Li Kangping mean since his sister-in-law and nephew came to the United States? Then live in the U.S. for a long time. Eight-year-old children are in the golden period of learning knowledge, and Ah Bing should collect his heart and learn knowledge after playing for a few days.

"Kangping? You and I both live in the United States? How do you take care of your stepfather and wife? Father-in-law categorically refuses to go to the United States? If the father-in-law does not come, the lady will not come. Could it be that you and I can only communicate with our hometown in Guangzhou by telegram or letter from now on? Isn't it desolate for my father-in-law and his wife to grow old and we can't serve our side? Li Chong looked worried.

There are some things that Li Chong can't say, but he really wants to say this, in case the old man and the lady are sick, and we are far away in the United States, I'm afraid we won't even see each other for the last time!

Li Chong was in a dilemma, not knowing what to do.

"Hey, it's hard to have both the family and the country." Li Kangping sighed lightly, "I plan to go back to China next year or the year after, and then I will consult my father in person and make a decision." In short, Ah Ping can't play all day, and it is advisable to arrange Ah Bing's studies in the United States first. ”

Li Kangping, the uncle, attaches great importance to the education of his nephew A Bing.

Before handling Ah Bing's study in the United States, Li Kangping chatted with Ah Bing.

Ah Bing was very excited when he first came to the United States.

Today, however, Ah Bing is depressed.

"Uncle Kangping, I don't like this house, it's so lonely." Ah Bing muttered.

There are a bunch of people living in the Li family compound in Guangzhou, in addition to Master Li, the two ladies, A Bing's mother and son, there are also several maids, and children who play with A Bing.

There is only one servant in this house in the United States, and there are no children of the same age to play with Ah Bing, so Ah Bing is not happy.

"Ah Bing, when you go to school, you can make friends, just like you did when you were studying in Guangzhou." Li Kangping said patiently.

Ah Bing is Li Chong's son, and Ah Bing's education is mainly supervised by Li Chong and his wife.

Li Chong has been in the United States for two years, and he is more familiar with the United States, and he hired a Chinese American teacher who understands both English and Chinese to teach A Bing English at home.

Let's say that Li Kangping came to Zeus Laboratory to learn about the research and development progress of the electronic TV project.

Zvorikin's electronic TV team currently has a total of 19 technical research and development personnel, who have bought some equipment, tools, and materials, and have not yet made the actual test products of photoelectric camera tubes and picture tubes, which are the core components of electronic television.

Li Kangping's request is that within this year, the Zvorikin team does not have to make photoelectric camera tubes and picture tubes, but must come up with a set of theoretically feasible technical solutions.

"Dr. Li, you see, we have actually made some test products, of course, these are waste products that do not meet the technical requirements." Zvorikin pointed to the waste product and reported the progress of research and development to Li Kangping.

"Photoelectric camera tubes and picture tubes are not so easy to make effective finished products, I know that these tasks are very difficult, let me see your technical solutions." Li Kangping picked up a piece of waste and looked at it, then put it down.
