That night, Sophie called: "Honey, I miss you!" What I'm going to tell you is that Walter is a funny guy and the cartoons he creates are so hilarious! I've finished shooting commercials, and it's live-action commercials, and I don't use animation techniques. Also, you know, there are a lot of job opportunities in Hollywood, and I got an offer from a director at Universal who wanted to make a Civil War movie, and he wanted me to play a role. ”

Li Kangping encouraged: "That's good news, Sophie, you should take this job." ”

"Kangping, then I'll have to stay in Hollywood, and I won't see you for a few months!"

"It's really hard to choose between a man and a job. Sophie, you better choose to work, your man is here, he won't disappear. ”

"Then I'll take the show! Kangping, love you! ”

"Sophie, I love you too."

After hanging up the phone, Li Kangping was engrossed in compiling "Atomic Physics".

Li Kangping received a letter from Ye Qisun yesterday, and Brother Qisun said that his doctoral dissertation had been completed.

Brother Qisun's doctoral project is research on high-pressure physics, and he is about to defend his doctoral graduation.

In other words, Brother Qisun is about to return to China, so Li Kangping worked hard to write "Atomic Physics", and he wanted to finish writing "Atomic Physics" before Brother Qisun returned to China.

At the same time, Li Kangping made every effort to prepare for the material wave speech at the APS annual meeting.

The first to reply to Li Kangping was Arthur Compton.

"Dear Lee: When you published Waves of Matter in 1922, I was fascinated by this paper. In addition, you have completed low-energy electron diffraction experiments, which undoubtedly provide solid evidence for the theory of matter waves. You and Professor Woodgate have both told me that the Woodgate Laboratory recently completed another experiment on high-energy electron diffraction, which is a new evidence supplement to the theory of matter waves. So, I think I'm going to support the theory of matter waves, and I'm going to be presenting at the 'Matter Wave and Low-Energy/High-Energy Electron Diffraction Experiments Keynote Session' at the APS Annual Meeting. ”

"Mr. Einstein publicly supported my 'Compton Effect' experiment, and I rolled on the ground with excitement! You know, without the support of Einstein, Bohr, Lorentz and other leaders of physics, the 'Compton effect' would have been imprisoned in Chicago! Wu and I couldn't even get out of Illinois! ”

"Speaking of Wu? I really liked this smart, rigorous, hardworking student. Actually?' The Compton Effect's work in Chicago, most of which was done by Wu. ”

"These months? Wu did a very fruitful experiment? He provides additional evidence of the 'Compton effect'. Another piece of good news is that Stanford's. Professor Ross was given spectral photographs similar to ours. ”

"Attached is Wu's experimental data."

"I hope you will also attend the 'Compton Effect Keynote Presentation' with me and Wu at the APS Annual Meeting."

"Have a good day. Arthur Compton? Chicago. ”

After reading the letter, Li Kangping smiled.

As everyone knows? The Woodgate-Lee experiment was not named after Woodgate or Lee Kangping. This academic term in physics was coined at the Solvay Conference in 1921? It was named after being proposed and approved by the leaders of physics.

Now, Arthur Compton has unilaterally named the results of his X-ray scattering experiments "The Compton Effect".

Let's review the Compton effect.

The study of the Compton effect can be divided into two phases.

In the first stage, with the help of Carl Compton, Arthur Compton designed and completed the experiment at Washington University in St. Louis? The first version of experimental data for the Compton effect was obtained. The core work of this phase was done almost by Arthur Compton alone? His experimental prowess was unrivaled in the United States, and he significantly advanced his theoretical skills at this stage.

In the second stage, under the guidance of Arthur Compton, Wu Youxun obtained the second version of the experimental data of the Compton Effect at the University of Chicago.

Wu Youxun tested the scattering curves of X-rays by various elements, and the results satisfied Compton's quantum scattering formula.

Moreover? Wu Youxun's experiment is still continuing, and he will provide the data of the third and fourth editions of the experiment? Thus thoroughly proving the universality of the Compton effect.

Academic friendships are interactive.

Arthur Compton was in favor of matter waves, and Lee Kangping certainly supported the Compton effect.

Li Kangping wrote back to Arthur Compton? He told Arthur Compton that he would be presenting at the "Compton Effect Keynote Presentation" at the APS Annual Meeting, and that he would follow the most basic academic conscience of a physicist. Support the Compton Effect in its strongest and most distinctive form.

Li Kangping's relationship with Arthur Compton is semi-public and semi-private.

His association with the remaining 7 physicists? It is purely academic and official business.

For example, Professor Chemberg of Harvard University wrote: "Dr. Lee: I think I'll be going to give a 'Keynote Lecture on Matter Ripple and Low-Energy/High-Energy Electron Diffraction Experiments,' but I'm probably just a listener, and I'm not going to say anything. ”

Another example is Professor David Nord of Worcester Polytechnic Institute, who is of French descent and puts it bluntly: "Even if you provide experimental evidence, I don't think the theory of matter waves is the right theory." I'm sorry, but I'm not going to be there for you. ”

Li Kangping wrote letters to a total of eight physicists.

So far, all eight physicists have replied.

Six of them were willing to attend the "Keynote Lecture on Matter Ripple Low-Energy/High-Energy Electron Diffraction Experiments", and two refused to attend.

Of the six who agreed to attend, only Arthur Compton expressed clear support, while the remaining five took a wait-and-see stance.

All in all, this was expected by Li Kangping, who continued to prepare for the APS Annual Meeting.

When President Warren Harding left Washington for a visit to Alaska in the early summer of 1923, he was considered healthy.

President Harding fell ill on the way back to Washington, and the cause appears to be cadaverine.

By the time President Harding arrived in San Francisco, his illness had morphed into pneumonia.

The American people pay close attention to the headlines on the front pages of the daily newspapers with great concern.

Just as the danger was about to pass, President Harding died suddenly on August 2, 1923---- and doctors in the White House blamed him for a stroke.

The whole of America is plunged into deep and sincere grief.

According to the U.S. Constitution, if a president dies suddenly while in office, the vice president immediately takes over as president.

The day after Warren Harding's death, U.S. Vice President John Calvin Coolidge was sworn in as President of the United States by a kerosene lamp in an unpowered farmhouse in Vermont.

From now on, the United States has entered the "Coolidge era".

Li Kangping has been in the United States for three years, and he has experienced three US presidents.

The American academic community is deeply saddened by the death of President Harding, and they also hope that President Coolidge will lead the United States forward.

As the president of the United States alternates between the old and the new, the APS annual meeting was held as scheduled.
