If these American books can have a positive effect on the construction of the physics department in Nankai, Li Kangping will have no problem giving thousands of dollars of books to Nankai University for free.

However, can the current situation of physics education in China really be completely improved by just shipping a few boxes of foreign language books back to China?

In fact, there have been people promoting the American education system in China for a long time. Tsinghua School, for example, uses American textbooks for natural sciences. The same is true of church schools, such as Yenching University.

Nankai University has no church background and is not sponsored by the Geng Foundation, this university has a relatively short history, and because it is a new university, President Zhang Boling and Director Rao Yutai can try new ways of education.

"Let's solve the problem in front of us first, and help Nankai University buy books."

Brother Yu Tai is also very familiar with the United States, and the titles of his books are all in English, including two editions of "Mechanics", three editions of "Electromagnetism", and several editions of "Atomic Physics...... These are undergraduate physics textbooks in the United States.

Universities in the United States are fighting their own battles, for example, for the course "Atomic Physics," Columbia College uses a textbook written by K.L. Radlove, Harvard University uses a textbook written by M.J. Mathis, and Caltech uses a textbook written by Robert Milligan. These three versions of Atomic Physics adhere to common basic principles, differing in specific details.

In addition to Columbia College, Harvard University, and California Institute of Technology, other universities in the United States basically use these three editions of "Atomic Physics".

In 1920, Li Kangping enrolled in a course in atomic physics, using K.L. Radlov's version of the textbook on atomic physics, and received an A+ in this course.

Li Kangping felt that Radlov's version of the atomic physics textbook was decent, with no highlights or shortcomings.

It can be seen that Brother Yu Tai is a little confused at this time, and he may not know which version of "Atomic Physics" is more suitable for his students, so he buys them all and buys them back to make a judgment.

The second part of the list of books listed by Brother Yu Tai is academic literature, which belongs to the field of academic research. Brother Yutai needs to recharge himself, perhaps in preparation for academic research in the future

Li Kangping handed over the list of books to a clerk, and he ordered the clerk to follow the map and send the books to Tianjin.

In Li Kangping's memory, in the late twenties and early thirties, China ushered in a period of relative stability, the Beiping Research Institute and the Academia Sinica were vigorously built and operated smoothly, and Chinese physics developed rapidly.

It is a pity that when Chinese physics first saw the light of day, the War of Resistance Against Japanese Aggression broke out.

Fortunately, the Japanese army bombed our campus and research institute, destroyed our equipment and materials, but our scientific talents continued the fire in the southwest, and after the founding of New China, the fire was transformed into an important weapon of the country and the education system and scientific research system of New China.

The purpose of teaching is to educate people.

With talent, everything is easy to do.

Following this logic backwards, there must be books to educate people.

Li Kangping, Rao Yutai, Ye Qisun, and Wu Youxun are Chinese physicists of this generation, and they studied abroad in college, and they studied and researched under the system established by foreigners.

Not every Chinese student has the opportunity to study abroad, so China needs to have a localized education system.

Li Kangping's ability is limited, he can only take into account mathematics in physics, and make some contributions to China's local education and scientific research in the field of physics and mathematics.

Continuing to read the letter, Li Kangping saw C.G. Darwin's reply.

"H.E. K.P. Lee......"

C.G. Darwin was polite in using the honorific title "Your Excellency."

"H.E. K.P. Lee: It is a pleasure to hear from you. Now, speaking of your views on physics, we have considered a few points that are relevant to our work in the meantime. We agree with you that the exact quantization caused by a collision can only be expected if the collision time is long enough compared to the period. But it's not entirely clear what is happening in other situations, whether we are experiencing a failure of the law of conservation of energy, or whether there is any other way out. Your faithful Charles Gaardon Darwin, London, December 25, 1922. ”

It seems that C.G. Darwin was a workaholic who wrote this letter on Christmas Day.

C.G. Darwin's frequent use of the word "we" in his letter shows that he was not fighting alone.

Li Kangping wrote back: "Your Excellency C.G. Darwin: It is a pleasure to receive your reply. To use a rough analogy, I can say that when Mr. A and Mr. B have money exchanges, the accounts between them must be clear. However, when it comes to a large banking enterprise with many branches, what must be balanced is the general settlement, and there can be very complex accounting relationships between the branches. ”

"I mention this non-technical metaphor to give you an idea of where our calculations begin when one makes the principle of energy statistically applicable between two atomic structures, that is, in the exchange of energy between atoms and α rays, as in the work of α-ray absorption. Of course, in other respects, I think the charm of your opinion is desirable. Your faithful K.P. Lee, New York, January 15, 1923. ”

In order to help C.G. Darwin understand the statistics of energy conservation, Li Kangping made a non-professional and superficial analogy of financial institutions.

One more friend is better than one more enemy.

I hope that C.G. Darwin can understand the physics implicit in this metaphor, and like his grandfather, break through the shackles of traditional concepts---- the shackles of man and God, and join this world war of physics with an advanced academic attitude.

After handling the president's business, Li Kangping returned to his apartment on Chenbian Street and began drafting "Atomic Physics".

Li Kangping wrote a manuscript in Chinese, and he hoped that Atomic Physics would be published in China and become a physics textbook for Chinese universities.

The first Chinese version of the university physics textbook in the last life was General Physics, written by Mr. Sa Bendong, which consisted of two volumes and was published by the Commercial Press in 1933.

Many Chinese physicists have the experience of studying in the United States, they are proficient in English, and can get American textbooks in China, they translated American textbooks into Chinese version of the end of the matter, why did it not until 1933 that the first Chinese version of university physics textbooks was published?

China's national conditions are different from those of Western countries, and it is not possible to completely copy the teaching materials of Western countries.
