Ah Bing's math tutor was personally sought by Li Kangping.

The math tutor, a Chinese student at Columbia University's School of Engineering, came to teach a math class on the evenings of the first, third, and fifth days.

Ah Bing was busy, and his mother Zhu Yunzhen didn't want to be idle.

Ms. Zhu, who attended a girls' school in China, said she did well in her studies and would have studied abroad if she hadn't married Ms. Li Chong at the age of 17.

After marrying into the Li family, Zhu Yunzhen, like other Chinese women, taught her husband and children and honored her in-laws.

Now, Zhu Yunzhen is going to the United States with her son, and she wants to become a new woman.

Li Chong was also open, and he said okay, do what you want to do. So Zhu Yunzhen also began to learn English.

Li Chong's family of three is living a happy new life in the United States, and Liu Shaowen is greedy.

Liu Shaowen also has a son, and his son is the same age as Ah Bing.

In fact, Liu Shaowen had long wanted to bring his wife and children to the United States for reunion, but his old man did not approve it.

At this time, the situation has changed, Liu Shaowen's brother and daughter-in-law have just given birth to a son, so it is possible that Mr. Liu will agree to Liu Shaowen's wife and children to come to the United States.

Liu Shaowen took several telegrams in a row to return to China and arrange for his wife and children to go to the United States.

At the APS Annual Meeting in August, physicists discussed a series of topics related to matter waves. Robert Milligan concluded the conference by saying that he hoped that the physicists attending the Symposium on Matter Waves would pay attention to matter waves and think seriously about matter waves after the conference.

With the publication of "High Energy Electron Diffraction Experiment" in Physical Review, all three papers in the series of material waves have been made public.

Li Kangping received letters from some American physicists one after another.

Professor Chemberg of Harvard University wrote in the letter: "Dr. Lee: I have been working on the theory of matter waves since I returned to Harvard, and in the face of a series of experimental results, physicists can only admit that although the old mechanics has been extended by the concept of relativity, it still cannot explain the phenomena with quantum intervention. In order to save physics, it is necessary to come up with new theories. ”

"Unlike artists, scientists are able to somehow get very precise results, even though the eternal seal isolates it from the beginning. On the contrary, when science hovers before us, painfully moving forward, as seen in real life, this is precisely the opportunity for science to function. Of course, everyone can think about rough sculptures and painters' sketches, but why don't people recognize physicists' sketches? ”

What does Professor Chembao mean by vaguely comparing scientists to artists?

Li Kangping felt that Professor Chembao seemed to have begun to lean towards the theory of matter waves.

At this time, Harvard University was very active in the American physics community, and Professor Duane of Harvard University, who had known Li Kangping for a long time, wrote in a letter: "Dr. Li: I said that I should not have asked you to publish Matter Waves in early 1922, because Matter Waves made us fools. Now, I'm going to ask you a few questions that seem 'stupid'. First, if the motion of the gas atoms associates the propagation of the wave, how is the resonance condition calculated? Second ......"

It can be seen that it is still very effective to organize a group of physicists to hold a meeting together.

Before the APS Annual Meeting in August, almost no one discussed the theory of matter waves with Li Kangping face-to-face or in letters.

The meeting was held, the spirit of the meeting was conveyed, and the physicists in the United States finally gave the matter wave theory the attention it deserved.

Professor Duane's questions are very specific academic questions, and Li Kangping is happy to explore such academic questions.

"Dear Professor Duane: I am glad to hear from you. Every time I have an important academic achievement? Can you always get your help? I express my sincerest gratitude for that. ”

"On your first academic question, how did I think about it? If the molecular velocity is small enough to omit the relativity term?/m0v, I will do the following math...... h/m0v。 ”

"On the second question? I think so, the integer n corresponding to the change in velocity δv gives the number of molecular states associated with the standing phase wave? Immediate access to ......"

“…… I hope my answer satisfies you. ”

Li Kangping answered Professor Duane's academic questions in academic language and sent the letter.

In mid-October, Sweden announced the names of the 1923 Nobel Prizes. The news of the Nobel Prize reached the United States with a delay of some time, and the American side immediately boiled over after receiving the news.

Newspapers in the United States reported on the front page: "Professor Robert Milligan of the California Institute of Technology Wins the 1923 Nobel Prize in Physics!" ”

Excited shouts rang out on the radio: "Professor Robert Milligan has become the second American person to win the Nobel Prize in Physics!" He's an American hero! ”

The five Nobel Prizes awarded this year? Only one American, Robert Milligan, won the prize.

As of 1923? Counting all five Nobel Prizes, only six people in the United States have won the Nobel Prize.

The six Nobel laureates in the United States are: Robert Milligan, Michelson; Chemistry Prize, Theodore Richards; Peace Prize? Theodore Roosevelt, Elihu Rott? Woodrod Wilson.

At present, no one in the United States has won the Nobel Prize in Medicine or the Nobel Prize in Literature.

In the first 20 years of the 20 th century, the United States could be said to be an engineering and technological power, but it was certainly not an academic research power.

Nobel Peace Prize laureates in the United States account for half of all Nobel laureates in the United States? Among them, Theodore Roosevelt and Woolold Wilson are former presidents of the United States.

So the United States loves peace? The United States is a country of peace.

Robert Milligan's No. Prize is too important for the United States.

As the radio host said? Professor Robert Milligan is a national hero, and Professor Robert Milligan deserves to be respected and loved by all Americans.

Robert Milligan received the award for "work on fundamental charges and the photoelectric effect."

This was actually the result of Robert Milligan's research seven years ago.

The Nobel Prize in science has to be scheduled, ranging from a few years to more than a dozen years.

Albert Einstein won the Nobel Prize for the "law of the photoelectric effect", and Robert Milligan proved the law of the photoelectric effect through photoelectric experiments, so he won the prize.

The awards are all related to the photoelectric effect, which is also good news for the quantum theory of light.

The wave-particle duality of light is moving in a positive direction.

The demonstration of wave-particle duality of material particles was carried out simultaneously.

Columbia University is the alma mater of Li Kangping, and on the theory of matter waves, Columbia University invited Li Kangping to participate in an internal academic seminar at Columbia University.
