The first part of "Waves of Matter", "Waves and Quantum", is actually very short, and Li Kangping wrote a total of 4 pages.

Click, click.

Part II: Light Quanta, Diffraction and Interference. 】

[As shown in the phenomenon of diffraction, the quantum of light, which we think exists, does not always propagate in a straight line.] 】①

（①，K.P.Lee，Phys.Rev.，51（1921）124。 ）

[I see the waves of matter as leading the transfer of energy, so that the waves and the quanta can be associated...... The new dynamics of free particles are to classical dynamics (including Einstein's special relativity dynamics) what wave optics is to geometrical optics......]

[I'm going to explain the interference fringes now.] I believe that the probability of an atom absorbing or radiating an atom of light is determined by the vector of a wave of matter associated with the atom...... No matter how small the intensity of the incident light is, there will be light and dark streaks...... This explanatory system, which borrows the principles of wave theory and introduces quanta, can be generalized to all interference and diffraction phenomena. 】

The second part, "Light Quantum, Diffraction and Interference," is shorter, with Li Kangping writing three pages.

He also wanted to count more words, but it was true that the water did not come out.

The basic theories of pure research often open up a directional path in academic thought. If you're too verbose, it'll seem low.

In the first part, Li Kangping proposed the concept of "matter waves".

In the second part, Li Kangping introduces an explanatory system that combines wave theory and quantum.

[Part III: Quantum, Gas Motion, and Fermat's Principle.] 】

[The integrand of the Fermat integral is the product of frequency and time, and it is only when there is a proportional relationship between energy and frequency that the action quantum can be introduced...... I calculated that the number of continuous standing waves with frequencies between ν and ν+dν per unit volume is nνdν=4π/UV^2ν^2 dν=4π/c^3βν^2dν......]

The third part is a little longer, and Li Kangping perfects his physical theories through complex and subtle mathematical processing.

Listening to Xin Feng and knowing that the leaves of the sycamore were falling, Li Kangping finished writing the third part, and it was the early morning of October 1, 1921.

Li Kangping was born on the eighth day of the eighth month of the leap month in the year of Gengzi. The Year of Gengzi 21 years ago was a year of suffering for the Chinese people.

Chinese celebrate lunar birthdays, but leap August occurs once in decades, that is, Li Kangping waits for decades to have a lunar birthday.

21 years ago, the eighth day of the eighth month of the leap year of Gengzi, corresponding to October 1, 1900 AD.

According to the Gregorian calendar chronology, Li Kangping's birthday is October 1, and today is his 21st birthday.

Although he was busy with his studies and career, he only had one birthday a year on the Gregorian calendar, and Li Kangping hosted a banquet for Mr. Zhou, Liu Shaowen and the rest of the Chinese Alumni Association to celebrate his 21st birthday.

On October 2, Li Kangping received a belated birthday gift.

The U.S. Patent Office approved Li Kangping's patent application for a super-regenerative circuit, which was classified by the Patent Office as a "product patent" with patent number: US-1571233.

US-1571233 is a product patent, and Li Kangping will not allow others to use it for free.

If others want to obtain the patent right to use the super-regenerative circuit, they must pay the patent royalty to Li Kangping.

In general, Li Kangping hoped to lie down and collect money, and he received the seventeen-year patent protection period of US-1571233 expired.

If someone else forcibly uses the US-1571233 patent without paying, then we will go to court.

Li Kangping was unwilling to fight and was not afraid to fight, so he had to fight when necessary.

At the beginning of October, the Solvay Conference was held as scheduled, and this conference was in fact a physics summit with the highest authority --- even a certain academic autocracy.

You can think of it this way, the participants of the Solvay Conference are all emperors, princes, feudal officials, commanders of the Imperial Forest Army, and chief eunuchs of the physical world.

Professor Woodgate arrived in Brussels at the end of September, and his laboratory at Columbia University is temporarily headed by his laboratory assistant Kangping Li.

As the temporary person in charge of the laboratory, Li Kangping came to the laboratory every few days to inspect it.

The full set of space quantization equipment that has made outstanding achievements is kept intact in the laboratory, and people come to visit and study from time to time. The Woodgate lab seems to have the rudiments of a research demonstration base at Columbia University.

We pioneered the world's first steady-state separation technology for atomic and molecular beams, and obtained experimental evidence of spatial quantization for the first time. So what is the follow-up direction of scientific research?

As we all know, Professor Woodgate has been busy with the Solvay conference lately, and he has been busy promoting his team's achievements to the world, so he does not have much energy and time to study the scientific research projects after the steady-state separation of atomic and molecular beams.

There are very few scholars who are truly immersed in academic research and do not ask about mundane affairs.

Many scholars have produced academic achievements and gained academic prestige, but they have fallen into the quagmire of conference affairs, speeches, sponsorship, company start-ups, and autobiographies.

We also know that Li Kangping's doctoral project is biased towards theoretical physics.

It's not that theoretical physics research doesn't need to do experiments, it's just that Li Kangping is still drafting the draft of basic theories at this stage, and it is not yet time to do experiments.

Alan is working on his master's project related to X-ray diffraction, which is still being revised and is not yet in the experimental stage.

After the tutor goes abroad, the students' studies are all self-conscious.

Li Kangping came to the Woodgate laboratory, he didn't see Allen here, Allen, this kid is not very conscious.

I walked around the lab, there was no problem, everything was normal. Li Kangping sat down at the table and wrote a letter with a pen.

"Brother Qisun,

It's been months since I've been away from the Highland Estate in New York State, and I've missed it so much. The day before yesterday, I received a letter from my brother, and learned the news of Brother Yutai, Brother Xiaoxian, Brother Xubao, Brother Youxun, and the gentlemen of this building, and suggested that we should get together during the Christmas holiday, either in New York, Cambridge or Boston. Please, brother, decide.

This is a question.

Ann.

Kang Ping bowed. ”

A few days ago, Li Kangping received a letter from Ye Qisun.

Ye Qisun said in the letter that Rao Yutai of Princeton University, Zha Xiaoxian (Cha Qian) of the University of Minnesota, Ding Xubao of Clark University, Wu Youxun of the University of Chicago, Sa Bendong of Stanford University, plus Ye Qisun of Harvard University, and Li Kangping of Columbia University, there are only a few Chinese students studying physics in the United States. Looking for him for a day, let's get together, how about Kang Pingyi?

Kangping was naturally looking forward to it, so he replied to the letter, agreeing to meet during the Christmas holiday, and the meeting city would be decided by the Qisun brother, and if it was set in New York, Kangping would handle all the matters.
