His girlfriend went on a business trip to California, and Li Kangping wrote papers in his house in Queens every night, and he wrote five pages a night, and even 10 pages if he exploded. Finally, the "Principle of Electron Spin and Incompatibility" is complete.

"Dear Monsieur Lorenz: I have written a new paper in which I consider the effect of spin on the set of stationary states corresponding to the motion of electrons around the nucleus. Since it has a magnetic moment, the electron will be subjected to a force couple as if it were placed at rest in a magnetic field, the value of which is equal to the vector product of the nuclear field and the velocity of the electron relative to the nucleus divided by the speed of light. The coupling will cause a slow precession of the spin axis, while the conservation of the angular momentum of the atoms is ensured by a compensatory precession of the plane of the electron orbit. The details of my calculations, derivations, and analyses are written in "The Principle of Electron Spin and Incompatibility". Attached papers. I also sent a copy of the same paper to Mr. Einstein. Wishing you good health. Lee, New York. ”

Li Kangping made two copies of the paper, one to the Netherlands to Lorenz, and the other to Germany, to Albert Einstein.

After completing the "Principle of Electron Spin and Incompatibility", Li Kangping went on to write "Atomic Physics".

【…… E. Rutherford completed the experiment of artificial nuclear reaction in 1919...... The radiation source is introduced into the brass container at a reasonable distance from the screen, and the air is pumped out...... α rays penetrate the end cover plate and fall onto the screen, and the light spot generated by it is the reference point where the microscope M aligns with the center of the opening......]

In addition to the textual description, Li Kangping also drew a schematic diagram of Rutherford's artificial nuclear reaction experiment, so that readers can more clearly understand how the experiment was done and the theoretical principles revealed by the experiment.

Lorenz and Einstein have not yet replied.

Li Kangping received a letter from Sommerfeld.

"Dear Dr. Lee, I would like to thank you first of all on behalf of my wife, she loved your gift! The time spent with you in the United States is a wonderful memory for me. ”

"At the just-concluded 'Bohr Festival Performance' in Göttingen, my students Wolfgang Pauli and Werner Heisenberg had an exchange with Mr. Bohr."

"On the question of the nature of light, Mr. Bohr's attitude puzzles me."

"I mentioned you to Mr. Bohr, who appreciates your contribution to the theory of space quantization and asked me to convey his greetings to you."

"Mr. Bohr will be visiting the United States and Canada in the fall, and you should have the opportunity to meet him face-to-face at that time."

At the same time, attached is the Berliner Zeitung. Mr. Einstein published an important article in this issue of the Berliner Zeitung. ”

"Have a good day. Sommerfeld, Munich. ”

Sommerfeld's letter contains a great deal of information.

Li Kangping interpreted them one by one.

Sommerfeld was a lovely little old man who loved young boys and was willing to nurture and promote them.

Pauli and Heisenberg, two hairy young men in their early 20s, were both students of Sommerfeld, and Sommerfeld took these two students to high-end academic conferences to introduce his students to physics masters.

In 1913, Bohr's theory of the atomic model was strongly attacked by the Göttingen School.

By 1922, Bohr was regarded as one of the greatest physicists by the same group of people in Göttingen.

In the early summer of 1922, Bohr was invited by the University of Göttingen to give a ten-day academic lecture at the University of Göttingen. The lecture was so successful that it became known as the "Bohr Festival Performance".

The "Bohr Festival Performance" became an annual academic event at the University of Göttingen, and this year, in the early summer of 1923, Bohr, who was already a prize-winner, once again gave an academic lecture at the University of Göttingen.

"Questions about the nature of light? Does Mr. Bohr's attitude puzzle you? ”

Li Kangping pondered over and over again the unclear words written by Sommerfeld in the letter.

The theory of space quantization is also known as the sommerfeld-bohr theory? Sommerfeld and Bohr had a close personal relationship.

While in the United States, Sommerfeld sent Arthur Compton's unpublished paper to Einstein and Bohr.

At this point? Arthur Compton's paper has been published. Albert Einstein wrote an article in the Berliner Zeitung? In it, he writes: "Of the results of recent experiments, only the Woodgate-Lee experiment and the Compton experiment are actually more important. The former proves the existence of the only quantum state, and the latter confirms the reality of the quantum momentum of light. ”

International Physics looks at Germany? German physics looks at Ai's.

Einstein's attitude was very clear? He openly supported the Compton experiment and considered it one of the two more important experiments in recent years.

We can't satisfy all physicists, we can satisfy Einstein, that's enough.

In fact, the problem of the nature of light has not been completely solved on a global scale.

But Einstein personally believed that the problem was solved.

So Li Kangping thinks so too.

Next? Li Kangping is ready to build momentum for his material wave.

Therefore, Li Kangping had to ask Einstein again.

Second Mahjong Factory? Poseidon Radio Company, these businesses are a matter of life and death for the company. The company's business affairs are indeed inseparable, otherwise Li Kangping would have gone to Germany to visit Einstein.

Li Kangping wrote to Einstein again, hoping that Einstein would help promote the matter wave in Europe.

In fact, Li Kangping asked Einstein for several projects, each of which was ahead of its time? It's complex and profound, and there's even a bit of philosophical thinking in it.

Fortunately, Albert Einstein was intelligent, thoughtful, gentle, broad-minded, and majestic? If this were to be replaced by someone else, I am afraid that Li Kangping would have been driven crazy a long time ago.

On the European side? There is the predecessor of Lao Einstein.

On the U.S. side, advancing at the same time? Li Kangping personally handled it.

There is no such thing as a leader in the American physics community today. Michelson and Milligan are big names in the American physics community? But they are not leaders who can unite and lead the entire American physics community.

Given the state of the United States? It is necessary to combine the high-end academic public relations line with the mass line.

However, the theory of matter waves is too high-end, so the "mass line" related to the theory of matter waves should be put in quotation marks.

This year's APS Annual Conference will be held in the late summer, and Li Kangping sees this meeting as a great opportunity.

Li Kangping came to the Woodgate laboratory and visited Professor Woodgate.

"Professor, congratulations on the success of your high-energy electron diffraction experiments!"

"Lee, you see, this is all the experimental evidence we have, and this experiment went better than I expected. A paper on the High Energy Electron Diffraction Experiment is being written, and at the end of the summer, whether it is published or not, I will present it at the APS Annual Meeting. ”
