Zurich, Switzerland.

In 1914, when Einstein was invited by Planck and Nernst to leave his alma mater, ETH Zurich, to teach at the Humboldt University in Berlin, Peter Debye took over his position as professor of theoretical physics.

Debye was a student of Sommerfeld, a position he held for ten years.

Last month, he received the January issue of the Annals of Physics, and he had already noticed Chen's paper.

Debye found this theory very interesting, and then he started with the quantum theory of radiation proposed by his predecessor Albert Einstein in his 1917 paper "The Quantum Theory of Radiation", and deduced the same scattering formula as Chen Muwu in another way.

With his thesis and his own derivation, Debye approached an experimental physicist at the school and asked him to design an experiment to verify it.

But a few days later, Debye received the February issue of the Bulletin of the Natural Science Society, which not only appeared again with Chen Muwu's paper, but also with the experimental verification results of the Cavendish laboratory.

This scattering formula was confirmed by experiments!

So Debye wrote a paper in a slow and methodical manner, which was also sent to Professor Planck's desk in the editorial office of the Annals of Physics in Berlin.

……

Of course, not everyone will start to change their minds about Chen Muwu's scattering theory after reading the preliminary experimental results published by Rutherford, and then try to accept it.

The fluctuation theory, which has been experimentally verified for one or two hundred years, has been deeply implanted in the minds of physicists, and there are still a large number of faithful followers of physics sages such as Huygens and Fresnel.

When the February issue of the Bulletin of the Natural Sciences was delivered to an office at the University of Copenhagen with the mail ship docking at the Baltic Sea dock, who would have thought that Nils Bohr, the new Nobel laureate in physics at the end of last year, would take a picture after reading his teacher's bulletin in experiments?

After completing his doctorate at the University of Copenhagen in 1911, Niels Bohr crossed the ocean to England.

He first went to J· J. Thomson presided over the Cavendish Laboratory in Cambridge, and a few months later he moved to Manchester, where he joined Rutherford's laboratory at the University of Manchester.

From 1911 to 1916, Bohr spent a total of five years in Manchester.

During these five years, Rutherford became Bohr's most respected man.

Although only fourteen years older than him, Bohr not only regarded Rutherford as his mentor, but also regarded him as a loving father.

Rutherford's laboratory in Manchester has also become the most admired sacred place in Bohr's heart, because in this laboratory, there will always be a group of energetic young people who come and go.

They included George Darwin (the second son of Charles Darwin, author of On the Origin of Species), from a family of prominent scholars, to the traditional aristocracy, to blue-collar children from the bottom of life......

These young people have different national and cultural backgrounds, different wealth and poverty differences, and status gaps.

But in that laboratory, in Rutherford's high-pitched voice and hearty laughter, there was no difference or estrangement between them, and everyone lived in harmony, working together to delve into the mysteries of science and seek the next breakthrough.

It was this atmosphere in the Rutherford Laboratory at the University of Manchester that deeply infected Bohr.

He felt that although his country, Denmark, was located in Europe, if the two world's academic centers, Britain and Germany, were compared to polite gentlemen, then Denmark's scientific level was basically equivalent to that of a savage in a foreign land.

If in order to improve the academic level of his country and promote the development of science and technology in the country, he must follow the example of his teacher Rutherford, imitate the laboratory in Manchester, and establish a similar scientific paradise on the land of Denmark, so as to cultivate batch after batch of fresh blood for the country's scientific research.

After returning from Manchester, Bohr entered his alma mater, the University of Copenhagen, where he became a professor of theoretical physics.

But he was never satisfied with the university professorship he held in his hand, because Bohr always had a bigger dream in his heart.

A few years ago, a paper by Sommerfeld successfully demonstrated the value of Bohr's atomic model, which raised Bohr's international reputation to a higher level as a Dane, who had just made a name for himself in academic circles.

With this strong momentum, Bohr was able to obtain approval from the school, and he went on to persuade the city government to offer the site and win a grant from the Carlsberg Foundation.

That's right, it's Carlsberg, who sells beer.

Carlsberg became a wealthy man in Denmark by selling beer, and before his death, he gave a portion of his estate to the Danish government, asking for the money to be given to Danish scholars to finance their academic research.

After receiving the land and funding, Bohr was finally able to realize his dream of building a "Institute of Theoretical Physics at the University of Copenhagen".

For the sake of this dream institute, he worked hard and even tirelessly to design the building of the institute himself.

But it also caused a bit of trouble, because as in the process of Bohr's dictation of his dissertation, he changed his mind so often that the construction project dragged on for more than a year, and it was not until the beginning of the previous year that the entire building was officially put into use.

After the house was built, enrollment became an urgent problem to be solved.

Not to mention attracting foreign students, even domestic students are a little skeptical of Copenhagen's ability.

Children of wealthy Danish families prefer to go to Germany and the British Isles on the European continent to receive the most advanced scientific education than to study in the capital.

But it was at this point that Bohr came into play again. Because just at the end of last year, he was awarded the Nobel Prize in Physics in 1922 of the year.

Today's Bohr can be described as both fame and fortune, and the scenery is unlimited.

That morning, as usual, he walked out of the house after breakfast and went to his office in the institute.

The secretary, who went to work early, had already put the February issue of the Bulletin of the Natural Sciences Society on Bohr's desk.

Bohr took out his pipe, filled it with new tobacco, struck a match and lit it, and after taking a deep breath, he picked up the February Bulletin of the Natural Science Society, which had been placed on his desk by his secretary early this morning, and flipped through it casually.

In the catalog, he saw the name of his mentor Rutherford.

But above the teacher's name, he saw the Chinese man again, Chen.

In last month's Annals of Physics, Bohr had already read Chen's paper.

Bohr scoffed at the idea of the quantum of light that was put forward in it.

Light quantum? Light quanta again?

Lao Tzu is playing light quantum!
