On this day, Li Kangping was about to go to the laboratory in Queens when he suddenly received a phone call from Professor Woodgate.

"Experiments on Electron Diffraction of Nickel Crystals" has been published in the latest issue of Physical Review, and Li Kangping's mailing address is the Columbia University Research Institute, and the professor asked him to collect the journal and the manuscript fee check. That's the good news.

Li Kangping came to the office of Professor Woodgate in Hertle Building, Columbia, and he flipped through the Physical Review, and the first paper was "Experiments on the Electron Diffraction of Nickel Crystals".

"Dr. Li, I think I should congratulate you on your Ph.D. and the publication of "Experiments on Nickel Crystals Diffracted by Electrons." The professor lit a cigarette, and he was both happy and a little disappointed.

"Professor, I thank you again for your kindness and support." Li Kangping said sincerely.

"Is your company okay?" The professor asked.

"The mahjong aspect is not bad, the physics aspect is just getting started."

"What exactly is the physical aspect?"

"Nipkov Disc."

"Oh, that thing."

The professor didn't seem interested in the Nipkov disk, and he added: "Lee, you know, it's not enough to just publish papers, and the promotion of academic results can't rely on this journal alone. Of course, publishing your paper in a journal is the first step. What I mean by this is that "Matter Waves" and its companion article, "Experiments with Nickel Crystals Being Diffracted by Electrons", need to be further promoted. ”

"Huh?"

"The Solvay Conference was the best platform for promotion, but it was only held once every three years, and it was clear that we could not wait until 1924 to act. In addition to the Global Physics Summit in Brussels, there are intercontinental conferences in London, Berlin, and Paris, as well as the annual physics conference in the United States. You should participate in these pure academic conferences as much as possible to promote your academic achievements. ”

"Okay, I'll try to do that."

The professor lit the second cigarette and continued: "There are many factors for Einstein's travels around the world, one of which is academic, he went to a country and brought his theories to that country. Although Einstein's theory has long since come to this country, it will not hurt for Einstein himself to spread it again in this country. ”

"Yes, you're right." Li Kangping agreed. Einstein's trip around the world is actually a brainwashing journey, and others helping Einstein promote brainwashing work are certainly not as effective as Einstein's hands-on.

"Intercontinental and national academic conferences are not held every month, but newspapers are published every day. Lee, I heard that you and Einstein kept up a correspondence, and you can keep it going. It's just that Einstein should be in the Pacific Ocean now, communication is inconvenient, and Mr. Lorenz is back in the Netherlands, so I think you should write to Mr. Lorentz and tell Mr. Lorentz about the results of the "Experiment of Nickel Crystal Being Diffracted by Electrons" as soon as possible. You met Mr. Lorenz a few months ago when we were doing the experiment, and you know that Mr. Lorenz cares a lot about the results of our experiments. ”

"Okay, Professor, I'll write to Mr. Lorenz at once."

"In the United States, I am willing to help with academic matters related to publicity and promotion."

Professor Woodgate has a point, that academic results are not just the end of the paper, you have to continue to operate, and turn the academic results on paper into substantial academic gains.

Professor Woodgate put forward some suggestions on the promotion of academic achievements, and Li Kangping accepted them all.

"Lee, you run your company, you do your own business, that's fine, and a lot of scientists are doing it – including Nobel Prize scientists. But I have to say that I regret losing you to my lab. ”

"Professor, our friendship is not confined to the lab."

"That's what I said, but ...... Lee, you don't work in my lab, and I can't seem to find academic inspiration. ”

Professor Woodgate is under the age of 50 and is in his prime of scholarship.

Li Kangping's master's thesis and doctoral dissertation were completed under the supervision of Professor Woodgate.

The space quantization experiment gave birth to the "Woodgate-Lee Experiment".

Woodgate and Lee continued to work together, and Woodgate Laboratory obtained experimental evidence for low-energy electron diffraction experiments for the first time in the world.

Professor Woodgate became a highly decorated experimental physicist, and two important technical lines in physics were related to him: the molecular beam method and the electron diffraction method.

In the current overall environment, these two technical routes have not exerted their full power, and in a few years, people may feel the true power of the backbone and branch lines of these two technical routes.

It is clear that the professor is not satisfied with the academic achievements he has already achieved, and he is eager to go further.

The professor said that he was out of inspiration, so Li Kangping helped the professor find inspiration academically.

"Professor, since the Woodgate Laboratory is the pioneer and authority of the molecular beam method and the electron diffraction method, I think the Woodgate Laboratory should focus on these two experimental techniques, continue to research, and continue to improve, so as to form a set of systematic academic theories of experimental technology."

"My doctor, can you be specific?"

"Professor, since the Woodgate Laboratory has completed the low-energy electron diffraction experiment, why not continue to try to create the world's first high-energy electron diffraction experiment?"

"High-energy electron diffraction experiments, oh yes, at your Ph.D. defense, someone mentioned this. You yourself have said that high-energy electron diffraction experiments are another direction to prove the waves of matter. ”

"Professor, regarding the high-energy electron diffraction experiment, I think so, first of all, the target material, not necessarily nickel, can use new targets such as aluminum, gold, platinum, etc. I think the design principle of the high-energy electron diffraction experiment should be ......"

In the previous life, Davidson's research on low-energy electron diffraction and G.P. Thomson's research on high-energy electron diffraction were published almost simultaneously. Therefore, the two were jointly awarded the Nobel Prize.

"Initiative" is a factor that is valued by academics in all fields, and the first person who achieved the first achievement will go down in history, and the people who follow it are not so famous.

In this lifetime, Li Kangping and Woodgate pioneered low-energy electron diffraction experiments with nickel crystals as the target.

So is there still academic value in high-energy electron diffraction experiments?

Of course there is.

On the one hand, if the high-energy electron diffraction experiment is successful, it will be a strong supplementary evidence for the theory of matter waves.

For Li Kangping, of course, he hopes that the more experimental evidence of matter waves, the better. Prove the matter wave in two ways: low energy and high energy, the left green dragon, the right white tiger, who dares to fight with me?

On the other hand, the high-energy electron diffraction experiment itself is a branch line in the technical route of electron diffraction experiment, which has high academic value.

Regarding the high-energy electron diffraction experiment, Li Kangping put forward his views.

"Lee, I suddenly have inspiration again." Professor Woodgate snuffs out his cigarette and regains his fighting spirits.
