Sommerfeld, who has a deep theoretical foundation, quickly saw the accuracy of Chen Muwu's theoretical derivation, and he and Einstein were very good friends, so Sommerfeld not only hyped up this new theory of using light quanta with momentum to explain gamma ray scattering and absorption, but also found Polly Rose, a professor of experimental physics in the physics department of Stanford University, in the audience after the lecture.

As an experimental physicist, Ross always insisted that experiments were the foundation of physics, but he did not look down on people like Sommerfeld who could only study theories.

But after all, he is a European professor invited by the school at a great price, and he still has to show some respect on the surface: "Professor Sommerfeld, congratulations on the success of your lecture at Stanford today!" Excuse me, do you have anything to do with me? ”

Sommerfeld got straight to the point: "Professor Ross, my intuition tells me that this paper in the Annals of Physics is probably the reason why gamma rays soften when scattered. I thought you might want to consider designing experiments to test this theory......"

Before the European colleague could finish speaking, Ross rudely interrupted him: "Sorry, Professor Sommerfeld, I have listened to your lecture and read the article, but I don't have that much time to waste on designing experiments for the absurd theories proposed by a Chinese. ”

With that, Professor Ross turned and left the room, leaving Sommerfeld where he was.

……

The "Annals of Physics" published on January 20 did not make much of a splash in the physics community, except for the fact that Compton, who had found a confidant in China, was "ecstatic about the poetry books."

Although it was endorsed by Planck and Einstein, the Annals of Physics was notoriously published without review, not to mention the fact that the author of the paper was a Chinese national, and his job was not to specialize in physics, but to be an engineer.

The combination of these debuffs led to the fact that most of the people who saw this issue of the magazine, like Professor Ross of Stanford University, took the paper as a joke entirely.

I can't imagine that the Germans, who have always been known for their stereotypes, have such a humorous side!

But another 10 days later, when the Proceedings of the Royal Society's Bulletin of the Natural Sciences were published in February, the winds in physics changed again.

The Journal of the Natural Science Society not only published the English version of Chen Muwu's paper in full, but also followed by an experimental bulletin that recorded the preliminary results of the experiments designed and carried out according to the theory of this paper.

The conclusion of the express report shows that the theory in Chen Muwu's paper makes a completely correct prediction of the experimental phenomenon!

Not only that, but the first author of the bulletin is George Thomson, the son of Joseph Thomson, former president of the Royal Society and current dean of Trinity College at Cambridge University, who currently works in the Cavendish laboratory.

The corresponding author is the director of the famous Cavendish Laboratory at the University of Cambridge, Rutherford.

In the last years of physics, when experimentation was king, the results of the Cavendish laboratory were undoubtedly like a divine decree.

And Rutherford's signature on the express is tantamount to stamping the emperor's jade seal on the holy decree.

Trains, ships, and postmen from all over the world were like stagecoaches and postmen in ancient times, promulgating the emperor's decree to all parts of the world.

……

McGill University, Montreal, Canada.

Half a month ago, Professor Yves, head of the Department of Physics, and his colleagues received a letter from Cambridgeshire, England, written by their former colleague Rutherford, former head of the university's physics department.

In the letter, Rutherford told his colleagues at McGill that the experiments on gamma-ray scattering and absorption, which they had begun two decades earlier, might finally have a theory of physics that could rationally explain their results.

He also asked them to keep an eye out for the February issue of the Bulletin of the Natural Science Society, which might contain the answers he had been dreaming of for years.

Today, the long-awaited "Bulletin of the Natural Science Society" has finally come to the school, and Yves, Gray, and other staff members who have been involved in gamma ray scattering experiments to a greater or lesser extent can't wait.

By the time I finished reading this theoretical explanation, the expression on everyone's face was different.

"I thought that the theory would be too complex to be within my shallow knowledge, so I thought I would be satisfied with doing the experiment perfectly. But who knows, he just applied a few theorems in classical physics, and this problem was solved! ”

Yves hurriedly comforted Professor Gray, who had a regretful face: "Joseph, you have done your best, we have all done our best.

"Who would have thought of this if it weren't for the paper linking Einstein's quantum theory of light to gamma rays?

"Don't you still think of gamma rays as electromagnetic waves, solving Maxwell's equations over and over again every day in vain?

"But that damn system of equations will only tell you over and over again that the wavelength of electromagnetic waves doesn't change because of scattering!

"I propose that we build another instrument and redo the experiment from 20 years ago to celebrate the birth of this simple and wonderful theory!"

……

This scene in the physics laboratory at McGill University is just a microcosm of the thousands of laboratories that are equipped to conduct experiments.

Since reading this issue of the Bulletin of the Natural Science Society, physicists around the world have had to take seriously the theories mentioned in Chen Muwu's paper.

They moved out of the gamma ray source or X-ray source, or according to the experimental design given in the paper, or designed new experiments themselves to verify whether the theory was correct.

Only Compton, who had just translated the paper into German and sent it to the Annals of Physics in Berlin, let out a wail: how can it be that people are one step ahead again! I can't always be alone with the wool!

But he didn't dare to complain too much, because Rutherford was also his teacher.

After receiving his Ph.D. from Princeton University, Compton was one of the first students to be sponsored by the National Research Council to study abroad in 1919 at the Cavendish Laboratory in Cambridge.

It was during his years in the Cavendish laboratory that he and Thomson Jr. came into contact with and studied the topic of gamma ray scattering and absorption, and Compton was able to further design the experiment after returning to China, and changed the gamma ray to X-ray.

Compton, who wanted to cry without tears, thought about it, and decided to make amends again, so he could only hurry up and send an English version of the paper with detailed experimental results to the "Bulletin of the Natural Science Society".

I don't expect to eat the meat, but I always have to take a sip of the soup, right?
