After Li Kangping finished answering, Professor Green was satisfied.

Professor Green's questions are more about basic theory, and Professor Harris's questions are more about applied technology.

Professor Harris said: "The experiments you have designed are ingenious, extremely difficult, and ingenious. I approve of the results of your experiments, and I would even like to repeat your experiments if you allow ---. ”

Li Kangping said generously: "Professor Harris, of course you can do this. Professor Woodgate and I are looking forward to your revalidation of our experiments. Do you say yes, Professor Woodgate? ”

Professor Woodgate laughed, "You are the protagonist of the defense meeting, and you have the final say." ”

Professor Harris continued: "Overall, your experiment is not only theoretically significant, but also provides a completely new technical means to separate neutral particles in different states in space. I think about it, this new technology, which was born in the laboratory of Columbia University, should be officially called ...... Well, what should it be? ”

Li Kangping blurted out: "I think it should be steady-state separation technology, professors, what do you think?" ”

Professor Harris snapped his fingers, snap! He said excitedly: "That's right, steady-state separation technology!" You invented steady-state separation! ”

"Steady-state separation technology, there is no doubt that it is an unprecedented new technology, and it has been successfully applied to space quantization experiments, and unprecedented experimental results and scientific results have been obtained." Professor Green concluded, "Lee, I think you could add a sentence to your paper: this technology, we named it steady-state separation technology. ”

Li Kangping accepted Professor Green's suggestion, saying, "Okay, I'll do it right away." ”

The three professors shook hands with Li Kangping, and Li Kangping's master's graduation defense meeting ended successfully in a happy and peaceful atmosphere.

You see, it is not difficult to deal with American physicists, as long as you come up with real and credible experimental evidence, your research results will soon be recognized by American physicists.

There are pictures and truths, and experimental photos reveal the truth. Professors Green, Harris and Woodgate signed Li Kangping's master's degree application, and after the review and approval of the Columbia Graduate School Review Committee, Li Kangping will receive a master's degree from Columbia University.

It is not uncommon for American professors to invite students to his home for academic exchanges.

Of course, it is not common for a male professor to invite a female student to his home.

The professors and students of Columbia University's graduate school are all men, so the invitation is an invitation between men and men.

Li Kangping followed Professor Woodgate for more than three months, and his first visit to the professor's home was on the eve of his master's degree.

Li Kangping learned that Professor Woodgate has a wife and two children, a son is 14 years old and a daughter is 7 years old.

I bought some gifts, and the professor's wife and two children were shared. Li Kangping drove away from Columbia and headed for the Bronx.

At this time, the Bronx was not a poor, sinful area, and the residents of the area were almost all economically well-off whites, and the law and order were better and the crime rate was lower.

The New York Yankees' home stadium is located in the most prosperous area of the Bronx, and the further north you go, the quieter it becomes, and the residential community is near farms, where people live in harmony with cattle and sheep.

Woodgate House is located in the north-central Bronx, a suburb of New York City. Woodgate House is a common American house, a two-storey single-family house with a large lawn in the front garden and some flowers in the back yard.

Mrs. Woodgate was gentle and kind, and like most American women, she was married and became a stay-at-home wife

The professor's son, William Jr., is a secondary school student, and his daughter Elizabeth is a primary school student.

A family of four with a pet dog. The male head of the family works to provide for the whole family, which is a typical American family structure.

Li Kangping gave the gift, and he was welcomed by the Woodgate family, and he felt that it was a very happy family.

"Come on, Lee, come to my study." The professor took Li Kangping up to the second floor.

Li Kangping carried his briefcase and followed the professor into the study.

"Did you bring twenty copies of the papers?" The professor asked.

"Of course." Li Kangping took out 20 copies of the paper "The Theory of Spatial Quantization Verified by Silver Atomic Beams" from his bag and placed them on the professor's desk.

Professor Woodgate handed Li Kangping a copy of a paper written by someone else, and the professor was amazed and said, "Look at this paper, take a good look, this is also written by a Chinese student, this Chinese student is very remarkable, he has measured the new Planck constant under the guidance of Professor Duane." This new Planck constant is more accurate than the Planck constant measured by Robert Milligan in 1917! ”

"Luckily, I didn't start the Planck Constant project, I couldn't have been more perfect than him!" The professor was very happy to have a meal.

Li Kangping read the paper with great curiosity, and the author of this paper is signed by C.S. Yeh and mailed to the Jefferson Physics Laboratory of Harvard University in Cambridge, Massachusetts.

C.S.Yeh, O Cowman!

C.S. Yeh, whose Chinese name is Ye Qisun, graduated from Tsinghua School in 1918 and then stayed in the United States at official expense to continue his studies in the physics department of the University of Chicago.

In September 1920, Ye Qisun entered the Jefferson Physics Laboratory of Harvard University Graduate School under the tutelage of W. Duane, a famous American experimental physicist.

In less than a year after studying for a master's degree, Ye Qisun measured the latest Planck constant and wrote a paper "Re-determination of Planck Constant by X-ray Method".

Li Kangping took a quick look at Ye Qisun's "Redetermination of Planck's Constant by X-ray Method".

In fact, there are two authors of this paper, one is Ye Qisun and the other is called H.H. Palmer.

Both authors are graduate students of Professor Duane, and the two graduate students thanked Professor Duane at the end of their papers.

Planck's constant h value measured by Ye Qisun and Palmer = (6.556±0.009)×10^-27 erg·s.

This result is more accurate than the h-value measured by Milligen in 1917 using the photoelectric effect.

Planck's constant is an important parameter in physics, and the academic contribution of the physics team at Harvard University is great.

Of course, the biggest credit should be given to Planck himself.

Either way, Ye Qisun is very remarkable.

Li Kangping said secretly, to meet the ancestor of Tsinghua Physics, Master Ye is above, and the apprentice Li Kangping is polite.

Professor Woodgate asked, "Lee, why are you in a daze?" ”

"Nothing, by the way, Professor, how did the paper from the Harvard physics team end up in your study? Hasn't it been published yet? So you're a reviewer? ”

Why Master Ye's paper appeared in Professor Woodgate's study made Li Kangping full of interest.
