Although Einstein spoke English poorly and never spoke it in public, that doesn't mean he couldn't understand it.

Obviously, he learned about Chen Muwu's identity as an engineer from Chen Muwu's self-introduction to Chattlet.

I can't imagine that Shelton's joke of looking down on Howard Wolwitz in "The Big Bang Theory" can go back to such a long history.

"Absolutely glad."

Faced with Einstein's invitation to study abroad, Chen Muwu hurriedly agreed.

It was a surprise to meet him, and he never imagined that Einstein would be so proactive.

"However, you may have to figure out your own way when it comes to tuition, and Humboldt University of Berlin will not give you a scholarship for a foreign student. Fortunately, the current mark is less valuable than waste paper, and it doesn't cost a lot to study in Germany. ”

He was telling the truth.

This trip was the only time Einstein visited East Asia in his life, and a large part of the reason why he was willing to travel so far was because the German mark had depreciated sharply after World War I, which forced him to go out to lecture and earn some relatively strong pounds and dollars to support his family.

"Also, have the few explanations you got published in a paper, and if not, I can include another letter of recommendation in my letter to Professor Planck, who is also the editor-in-chief of the Annals of Physics."

Chen Muwu finally heard the sentence he wanted to hear the most since he crossed over.

He hurriedly took out the cardboard folder he was carrying, and took out a thick pile of foreign paper, which was densely covered with letters typed on a typewriter, and everyone could see that he had prepared for this series a long time ago.

"Doctor, I have not submitted a paper on the exact solution of field equations to a physics journal, but I have submitted another paper to a European physics journal, which is a copy of the paper, and I hope you can review it if you have time."

"Oh? What is this article about? ”

"Light quantum," this is in addition to the theory of relativity, light quantum is another major contribution of Einstein to physics, Chen Muwu really knows how to do what he likes, and the sycophants are patting in circles, "The 'light quantum hypothesis' proposed in your 1905 paper has inspired me a lot, especially after being confirmed by Milligan's experiments in recent years, I wonder if I can apply the light quantum theory to other places."

"Then I thought that when Professor Arthur Yves of McGill University began to study the absorption and scattering properties of gamma rays in 1904, he found that the scattered gamma rays tended to be 'softer' than the incident rays.

Since then, further experimental studies by David Florance and Joseph Gray have given more precise data and conclusions, but they have never been able to explain this physical phenomenon.

"So I thought of the theory of light quanta proposed by you, doctor, and further developed it, assuming that light quanta not only have energy, but also momentum, so that these light quanta with momentum and the free electrons in the scattered materials collide inelastically, and the theoretical results obtained are in perfect agreement with the experiment.

"It's just that I don't have the conditions for experimental verification here, so I had to write a paper on the theory explaining this phenomenon, and submitted it to the British Journal of Philosophy and the German Annals of Physics, respectively, hoping that the experimental physicists who can see this paper in other parts of the world can do experiments to verify the explanations mentioned in this paper.

"The paper was sent out about a month and a half ago, and if you calculate the time, it should have reached the editorial offices of the two journals by now. My only concern is that the reviewers of these two journals will throw papers in the trash without even reading them because of my status as a Chinese journalist.

"So I brought this paper to today's symposium in the hope that after reading the paper, if you think the paper is worth recommending, please help me write a letter of recommendation to the editorial offices of the two journals, at least let them read the paper, and not throw it in the trash.

"As for the way, the Trans-Siberian Railway has not yet been opened[1], and letters from here to Europe will require at least forty days by sea, and I hope that you will send telegrams directly to these two periodicals, and that I will bear the cost of sending telegrams."

Einstein listened to this, smiled and waved his hand: "Chen, it can be seen that you have a very wide range of knowledge in physics, and your idea of giving momentum to the light quantum is very novel, I really don't know how many such genius ideas are in your brain!"

"But I'm going to a banquet soon, and I don't have time to read the paper I've written, so I'll have to wait until I get back to my hotel room in the evening to read it.

"If there is no problem, I can send a telegram to Germany and Britain tomorrow, and as for the cost of the telegram, you don't have to worry, I think the guys at the German consulate in Shanghai should be very willing to do it for you."

As a Jew, the calculation of money is a skill that has been passed down from generation to generation in the blood, and Einstein was not immune.

When Cai Yuanpei invited Einstein to give a lecture at Shao University for the first time, he was rejected because the remuneration was too small.

Einstein's original plan for this trip to the east was to go north after arriving at the sea and give lectures at the University for two weeks.

However, because the Jews in Jerusalem urged him to stand on the platform of the Hebrew University, and the Swedes urged him to go to Stockholm to receive the Nobel Prize, Einstein had to cancel the trip to the university.

After learning the news, Cai Yuanpei was naturally disappointed, and couldn't help but secretly ridicule in an article in the "Journal of Shaojing University".

However, Chen Muwu is happy to see this, after all, this can save himself a lot of expenses.

Nowadays, sending telegrams is not cheap at all, and a Chinese character in China is two cents and a dime of foreign characters, and a foreign text is eight cents, not to mention sending it abroad.

If Chen Muwu is really made to pay out of his own pocket, that astronomical amount is estimated to make him lose money.

During the conversation, the three of them had already walked along the four-horse road, from Hexing Road, where the Ministry of Industry Bureau is located, to the end of Fuxian Road.

Chen Muwu refused Chatterley's invitation to dine, he was not interested in attending a group of Jews, after all, they were not the little Jews I had seen in "The Great Time", but a fat-headed and big-eared foreign devil.

What's more, although the situation of the Jews in Europe and the United States is not very good, in China, they are still a group of hateful colonial invaders.

To put it mildly, Chen Muwu had no sympathy for what their compatriots would do in the future because of what these people were doing in the concession.

In front of the Yipinxiang restaurant, he and Einstein were separated.

Chen Muwu was not worried that Einstein would not send a telegram recommendation after reading the paper.

Because he knew very well how much weight the paper he handed over to Einstein weighed in the history of physics.

If there was one person in the world who believed in the existence of light quanta in the eighteen years from 1905 to 1923, it must be Albert Einstein.

Now that Chen Muwu has handed over a paper on light quantum to Einstein, it will surely arouse great interest in the latter.

Great oaks from little acorns grow..

Now that we have taken the first step, we can only "do our best and obey the destiny of heaven".

[1] Author's note: The fact that it has not been opened to traffic here does not mean that the Trans-Siberian Railway has not yet been completed and put into use, but that the operation of the line has been interrupted due to the civil war in Soviet Russia. Moreover, at this time, the government of Minyuan and Beijing had not yet signed a relevant document with Sulian on the use of the Trans-Siberian Railway for postal passenger transportation, so the postal route between China and Europe at this time had to rely entirely on sea routes.
