Physicists in the United States were originally working on their own and were not so united. Under the influence of various factors, this group of physicists in Manhattan's morning heights united.

Regarding the matter wave and the Compton effect, educating students about popular science or publishing articles in support of it is a substantive and universal propaganda, and Li Kangping is happy to see this situation.

"Li, accompany me to the lab, and I'll introduce you to a new student."

After the meeting, Woodgate and Li Kangping went to Woodgate's laboratory together.

On the way, Woodgate said: "Allen has already obtained his Ph.D., he is determined to go to Germany for further study, and the Barnard Foundation will provide Allen with a one-year scholarship, so Allen will definitely go to Germany, and he will leave next January at the latest." ”

Li Kangping nodded and said, "Yes, I know about this, Alan told me." Allen has participated in three important experiments: space quantization experiments and low-energy/high-energy electron diffraction experiments, and his current choice is to go to Berlin or Munich or Göttingen? I think he'll go to Berlin because Einstein is in Berlin. ”

"No, you're wrong, Alan chose Göttingen."

"Oh, is it? Göttingen is fine, so let him go to Göttingen. ”

"Lee, you know, despite the remarkable achievements of American physics in recent years, Germany is still the center of physics in the hearts of many physics students. So they all want to go to Germany, and if they can't go to Germany, then go to England or Copenhagen. ”

"I read a report that in recent years, Germany, Britain and Denmark have spent exactly half as much on physics research as half the United States. As for Mr. Bohr's Copenhagen Institute, the Danish government actually gave only a small amount of money, and Mr. Bohr recently visited the United States and asked the Rockefeller Foundation for $100,000 in sponsorship money. ”

"It's not just about money, it's about the number of physics masters, their influence, and the academic atmosphere that has been formed for a long time. In the field of physics, the United States could not surpass Germany. Lee, you have also seen that even though Germany was defeated in the war and Germany was shriveled by Britain and France like oranges, Germany still led the world in physics and mathematics. ”

"As long as that group of academic masters exerts their power in Germany, Germany will never be defeated in the academic field. This is a systemic problem, the German academic system will not collapse because of the war, and, after the European war? On the contrary, the German academic system has produced more outstanding young scholars. In front of the Germans? We Americans have always been students, if we try hard enough? Maybe catch up with the UK. ”

Professor Woodgate said as he walked, "Lee? You now understand, why is Professor Milligan respected and loved by physicists all over the United States? Because Professor Milligan built the physical system of the United States in the United States, he set an example in California. How many people love Professor Milligan? The main thing is to love his experiments with the photoelectric effect. And people like us who respect Professor Milligan? It is to honor him in essence to help American physics get rid of student status. ”

"Speaking of Professor Milligan, let's talk about Mark by the way. You know, Mark was recommended by Professor Milligan to come to me, now? Professor Milligan became a Nobel laureate? So Mark quit my job as a teaching assistant, and he's about to return to California to rejoin Professor Milligan's team. ”

Speaking of this, Professor Woodgate is slightly melancholy.

When Mark first arrived at Columbia in the spring of 1922, he was unknown. At this time, Mark was one of the authors of "High Energy Electron Diffraction Experiments"? He had made up enough academic capital in just over a year to return to California? It looks like a homecoming home.

"From the beginning of 1921 to now, less than three years? I feel like I've done all the academic research work of my life. "Professor Woodgate's hair is already sparse, and it is currently close to the level of a bald head.

"I want to take a break for a few years? Teaching undergraduates, writing monographs? For me, it's rest. That's right? I will write an academic monograph that includes all my experience in the past 20 years of academic research. Mark and Allen were gone, and I didn't want to take in new graduate students, but the Columbia graduate school begged me to recruit a new graduate student, and I was soft-hearted, so I agreed. ”

The new graduate student, 25, is an Austrian Jew who immigrated to the United States with his parents when he was a year old. His father was a fellow in a Jewish-owned grocery store in New York, and their family earned only $500 a year. ”

"But this kid is very smart, he is a good student of physics. Lee, I would like to introduce him to you, if you have a project in your lab, you can consider him. ”

Professor Woodgate made it very clear that he wanted to do light jobs, such as teaching undergraduates and writing books.

In that case, don't recruit graduate students.

Professor Woodgate's explanation was that he was soft-hearted, so he obeyed the arrangement of the Columbia graduate school and recruited a new Jewish graduate student.

If you recruit a graduate student, then you have to give him a project to do, otherwise he will not be able to write a thesis and get a degree.

And Professor Woodgate doesn't want to do new projects in the coming years.

Aren't you delaying your child?

Columbia has other physics supervisors, and it is okay for Professor Woodgate to transfer his newly recruited graduate students to other supervisors at Columbia.

Professor Woodgate, however, did not do so, and he hoped that Li Kangping would "train" his graduate students.

In general, this is unreasonable, but reasonable.

So, Li Kangping met the poor graduate student in the Woodgate laboratory.

"This is Isidore Rabi. This is Dr. Lee. Professor Woodgate introduced the two to each other.

"Nice to meet you."

"Me too."

Li Kangping shook hands with Isidore Rabbi and looked at the emaciated Jew, who he felt should be given a new scientific project.

"Isidó, where were you doing before you came to Columbia Institute?" Li Kangping asked.

"I did my undergraduate degree at Cornell University, where I enrolled in electrical engineering, but I got a bachelor's degree in chemistry. Then I went on to get a master's degree in chemistry at Cornell University, and then I came here. Rabbi Isidore said honestly.

Li Kangping said: "You are a master of chemistry, but this is a physics laboratory. ”

"In fact, half a year before I got my master's degree in chemistry, I already knew that physics was the subject I would strive for." Isidore Rabbi explained, adding: "I thank Professor Woodgate for giving me this opportunity, and I have heard of Dr. Lee's name, we Jews don't care about formalities, as long as I can study physics, study physics, I will do anything for you." ”
