Although Bohr and Einstein had a good relationship in private, they have been in love and killing each other since they met.

Today, Bohr still follows the old traditional view in his bones, and in his mind, Einstein is good everywhere, but it is absolutely unacceptable to put forward the idea of light quantum.

If we admit that such a quantum of light does exist, as he said, then both Huygens's wave theory and Maxwell's theory of electromagnetism will be completely overthrown.

Last year, Bohr and Einstein both won the Nobel Prize in Physics, with the former being the winner of the prize that year and the latter being the winner of the prize the year before. 【1】

As soon as he learned of the award, Bohr immediately wrote a letter to Einstein, who was lecturing in the Far East, congratulating him on finally winning the Nobel Prize.

The letter is written humbly, and he says that he has been able to achieve something because of Einstein's foundational contributions. Therefore, Einstein was able to win the Nobel Prize before him, and Bohr felt that it was a "great blessing".

Because the theory of relativity is still controversial in the physics community today, when Einstein was awarded the 1921 Prize in Physics, the Royal Swedish Academy of Sciences gave the award not because of the theory of relativity, but "in recognition of his research in theoretical physics, especially for the discovery of the law of the photoelectric effect". At least the law of the photoelectric effect has been verified by Milligan's precise experiments, and its accuracy is beyond doubt.

On December 10 last year, the day of Nobel's death, Albert Einstein, who was still lecturing in Waben, was unable to attend his award ceremony in Stockholm.

After King Gustav V of Sweden presented Einstein with the prize, he invited this year's laureate, Bohr, to the stage.

However, Bohr's speech caused an uproar in the audience, because in his acceptance speech, he pointed the finger at the photoelectric effect that had just won the award, completely refuting Einstein's quantum theory of light, saying that it was wrong to explain the photoelectric effect with this theory!

It can be seen from this that Bohr is so resistant to the theory of light quantum that he can say such a tear-down at the award ceremony so mercilessly.

Therefore, at the beginning, Bohr was very disdainful of Chen Muwu's paper, and it was just a theory, which was no different from civil science without experimental verification.

However, in the ensuing "Bulletin of the Natural Science Society", he not only saw Chen Muwu's paper again, but also had the experimental verification done by his teacher Rutherford.

The teacher's experiment concluded that gamma rays, after refraction, did indeed appear in the kind of phenomenon predicted in the paper.

This is something Bohr absolutely does not want to see!

The more he thought about it, the more angry Bohr became, and asked his assistant Hendrik Kramers to come to the office to find him.

In 1916, after receiving a master's degree in science from Leiden University in the Netherlands, Kramers wanted to study abroad during his doctorate.

He wanted to go to the University of Göttingen and be under the tutelage of Professor Max Born.

However, because Europe was fighting World War I, Kramers could not go to Germany, so he had to go to Denmark, which was a neutral country with the Netherlands, and became a doctoral student of Bohr, who had just returned from the University of Manchester and was not known at the time.

After graduating with a Ph.D., he was retained by his teacher Bohr as an assistant and became an associate professor at the Institute of Theoretical Physics at the University of Copenhagen.

Now he has just devoted himself to scientific research, so he is as motivated as a chicken.

Kramers heard something seem unusual about the teacher's tone on the phone, so he trotted all the way to Bohr's office.

"Hans, come and read this paper!"

Kramers honestly took the "Bulletin of the Natural Science Society" from Bohr's hand, spent a long time carefully reading Chen Muwu's paper and Rutherford's experimental letters, and then raised his head and said to his boss: "Teacher, didn't this paper have been published once in the Annals of Physics last month?" ”

As a Dutchman, he reads German much more easily than English.

"yes, what do you think?" Bohr asked with a frown.

Kramers replied truthfully: "The derivation process in this paper is very concise, and the knowledge used is very rudimentary, like a physics undergraduate can easily do it." However, I think it's interesting that he sees light as a 'particle'! From the photoelectric effect to the present experiment, light is likely to be a particle! ”

"How can light be a particle! I want you to use your brain, if light is particles, then how can there be light and dark interference fringes behind the two slits? ”

"But, my teacher, didn't Lord Rutherford of Cambridge also attach the results of the experiments of Cavendish Laboratories to this?"

"Nothing! Light is definitely not a particle! ”

……

Hearing Kramers's answer, Bohr, who had always been mild-mannered, was furious.

He feels that his assistant has been brainwashed by a demon called "Photon", which is an absolutely unforgivable sin.

After this, the tobacco in Bohr's pipe changed again and again, and the matches were struck one after another.

He took the trouble and spent a whole day on Kramers, repeatedly arguing from various angles such as science and philosophy that "photons" could not exist in this world.

Eventually, Bohr finally convinced his assistant that he had been lured astray after reading Chen Muwu's papers.

It wasn't until dusk that Kramers dragged his tired body out of Bohr's office.

Exhausted that night, he did not go home, but was admitted directly to the University of Copenhagen Hospital. 【2】

A few days later, when Kramers, who had been recuperating in the hospital, had just been discharged, Bohr asked him to compile a correspondence from his conversation with him that day, or rather his unilateral lecture, and send it to the Royal Society of Science in London, England, signed with their names.

……

Compton's experimental data, Yves's reply to Rutherford, Debye's submission to Planck, Bohr's correspondence against Chen Muwu......

Countless letters were sent from universities across Europe and the United States, passed through the busy postal system, and eventually snowflakes into England and Germany.

The contents of these letters are not the same, but what they all have in common is that they cannot avoid a new concept of physics.

A ghost, a ghost named "Photon", roams over the European and American physics community.

Of course, only one of these letters was sent from China.

Although it is not a photon, the shocking ability contained in the content is not weaker than the current photon theory.

I wonder how big a shocking wave it will be if this stone is thrown into the physics world that is still rippling?

At this moment, the author of this letter is sitting on a train of the Gyeongbong Railway, "galloping" towards the east.
