Reborn and become a Great Scientist

Chapter 83 31 Old Acquaintances and New Friends

In addition to spending a few days of leisure time with old Thomson, accompanied Ye Gongchao to Chinatown in London to buy all kinds of spices for the kitchen, and went to the Cam River to participate in club swimming activities at noon every day.

Chen Muwu, who stayed at Cambridge University, met an old acquaintance and a new friend this summer.

Yan Renguang, head of the Department of Physics at Beijing University, chose to retain his teaching position and leave school after this year's course, and went abroad to various universities in Europe and America to investigate physics education and laboratories.

In the original time and space, Yan Renguang did go abroad for a year of investigation, but that was in the summer of [-].

And now the reason why he set off a year earlier had a lot to do with Chen Muwu.

At the beginning of this year, Chen Muwu, who finished his lectures at Bei University, announced that he would donate all the manuscript fees after the publication of his lectures to the Department of Physics for them to build a physics laboratory.

The money was actually not much, but with the publication of Chen Muwu's second paper, he and his time travel ideas became popular all over the UK in an instant.

The reporter of "The Times" stationed in the Far East bought the English publishing rights of this speech from Beida at a high price.

In this way, the remuneration that Chen Muwu could get was greatly increased, and at the same time, it also meant that the laboratory funds of the Physics Department of Bei University became more and more abundant.

Chen Muwu made such a big noise in Europe, but it was rarely mentioned in domestic newspapers.

They are more keen to publish the battles between warlords, the attacks between politicians, and the train robbery on Jinpu Road that shocked the world.

If it weren't for the British journalists who came to buy speeches, the professors at Bei University would probably still be kept in the dark.

They only inquired about bits and pieces of news through various channels.

Then after more than a month, after receiving various physics journals from Europe one after another, I read two papers published by Chen Muwu and physicists all over the world on gamma-ray radiation. Various experiments with scattering.

Only then did Yan Renguang understand why Chen Muwu refused when he invited Chen Muwu to stay in Beida as a teacher.

It turns out that this young man has no ambition at all. The gamma ray he studies, let alone Bei Da, can't even find a gamma ray source in the whole country!

Staying in the country can only delay the future in vain.

With such a large sum of money, and some stimulation from Chen Muwu, Yan Renguang, who originally planned to order some basic experimental equipment from foreign firms in the Haihai Concession, changed his mind.

After discussing with the professors in the department and acting principal Jiang Menglin, he decided to go to Europe and the United States himself. While inspecting the advanced education of various universities, he also bought some advanced equipment for Bei University.

In this way, after the summer vacation began, Yan Renguang came to Europe by train on the Trans-Siberian Railway, visited Humboldt University in Berlin, University of Göttingen in Germany, and Marie Curie’s laboratory in France, and then crossed the English Channel and came to Cambridge University, where the Cavendish Laboratory is located, also met Chen Muwu who stayed here.

When Yan Renguang was still in Germany, he specially wrote a letter to Chen Muwu, informing him of his next itinerary in England, and asking if he had time to give him a certain reception.

When he was giving lectures at Bei University, Yan Renguang took good care of him as a junior.

Now that it's his home court, Chen Muwu feels that he can't wait for the opponent.

That's why Chen Muwu was able to calculate the time accurately, and waited outside the Cambridge Railway Station in advance to meet this senior physicist who came from a long way from China.

"Han Chen, long time no see!"

Yan Renguang, who had just walked out of the station, saw the tall man standing in the crowd at a glance.

At the same time, Chen Muwu also spotted the other party, and he quickly walked towards Yan Renguang's direction: "Yao Gong, the journey is full of dust and dust, it's really hard work for you!"

The two sat in a taxi outside the train station waiting to pick up guests.

As soon as he got in the car, Yan Renguang asked straight to the point: "Hanchen, you are really a real person. When you were still in Bei University, your paper on gamma ray scattering should have been published in Europe, right?" ?”

Chen Muwu nodded.

Yan Renguang let out a long sigh: "Oh, what a formidable young man! No wonder you look down on our teaching position in Bei University."

"Sir, that's not the case. It's really because the younger generation has little talent and learning, and I'm afraid I can't take on the big responsibility, so I refused to accept it."

"Don't be modest. I have heard about the things you did in the UK when I was visiting Germany and France some time ago. Hanchen, these papers of yours have really given us Chinese people a face. Annoyed.

"When I was in France, Marie Curie even asked me if there were any smart students like you in China, and if I could recommend some to her laboratory.

"Hanchen, your earth-shattering talent is a great Buddha. If you really stay in this small temple in our Bei University, it will be a pity to lose your talent."

Chen Muwu didn't expect that even Mrs. Curie had a good opinion of him.

But counting the time, Mrs. Curie should be able to find her first Chinese student in a short time.

Yan Jici, who graduated from the National Southeast University, should have boarded the ship to study in France by this time.

The carriage quickly pulled the two of them from the train station outside the city to the center of Cambridge.

Even after getting out of the car, Yan Renguang still praised Chen Muwu.

From the former's words of thanks, the latter knew that the British paid a lot of money to buy one of their speeches.

Chen Muwu advised the dean of the physics department who had taken care of him a lot at Bei University not to be polite, as long as it can improve the domestic physics education, what is his little money?
Accompanied by Chen Muwu, Yan Renguang visited the famous Cavendish Laboratory.

When he was in the open laboratory on the first floor, he saw the dark oil-stained tables and the very crude instruments on them, and even many of them were self-made. Although Yan Renguang didn't say anything, but The astonished expression on his face could not be concealed.

Chen Muwu was also very embarrassed. The situation was like this. Although the Cavendish Laboratory was well-known, it didn't have much money. It could provide experimenters with a better experimental environment and experiments.

Trinity College is rich because a large number of successful and famous alumni donate to the college every year, and then the college uses these donations to invest and make money with money, accumulating huge wealth.

The Cavendish Laboratory relies entirely on funding from the Cambridge University Council.

Although the annual funding of [-] pounds may not seem like much, it already accounts for nearly one-tenth of the total annual funding given to Cambridge University by the British government.

Chen Muwu brought Yan Renguang to the laboratory where he did visible light scattering, and showed him how he started from splitting sunlight and finally completed the experiment step by step.

After watching all this, the dean of the Department of Physics of Bei University finally couldn't help exclaiming: "Han Chen, do you usually conduct experiments under such conditions?"

Chen Muwu smiled wryly and nodded.

"It's not easy, it's really not easy," Yan Renguang kept shaking his head, "In this experimental environment, you can still achieve new results.

"To be honest, I feel that Cavendish's experimental environment is not too different from our Bei University. You can easily find these experimental equipment in China.

"But you can write a paper that can be published in a top physics journal in this shabby room, but we can't do anything. It's really 'people die when comparing people, and goods are thrown away'!

"However, Hanchen, does this experimental phenomenon have any practical significance now? I read the Journal of Natural Sciences in July in Germany, and people commented on another paper of yours that perfectly refuted Bohr's absurd point of view. I like to talk about it, but I seem to have ignored this new experimental phenomenon you discovered."

Speaking of the scattering of visible light in liquids, Chen Muwu's third paper has indeed not caused much repercussions in the physics community.

However, this paper has a faint trend of "blossom inside the wall and fragrance outside the wall", because some chemists found that the new scattering spectrum discovered by Chen Muwu is very useful in the study of molecular vibration and molecular rotation.

Some people have even begun to introduce this new method into chemical analysis. As long as a specific spectral line can be found in the spectrum, it can be determined that there is a corresponding component in the scattering material.

Although the efficiency of this method is not high due to the problem of the light source, it can be regarded as a new idea for chemical analysis.

After coming out of the Cavendish Laboratory, Yan Renguang was recommended by Chen Muwu to meet with Old Thomson, the dean of Trinity College.

When the two of them met, they were all high-sounding polite words without much practical significance.

It is not so much a visit, but a homage to the predecessors of physics by the younger generations.

Before Yan Renguang left, Chen Muwu specially invited Ye Gongchao, and the two cooked some Chinese dishes together to treat the head of the Physics Department of Bei University, who was about to embark on another journey, as the last practical banquet in the UK .

After leaving Cambridge, he will sail from England to the United States to continue his research trip on the North American continent.

During the banquet, Yan Renguang kept lamenting that compared with foreign countries, China's physics education still has a long way to go. As educators, they should work hard and not let others fall further and further behind.

Before the dinner was over, Yan Renguang, who became more and more excited as he chatted, took Chen Muwu's hand and once again invited him to teach at Beijing University after graduation.

But for this invitation, Chen Muwu, who hadn't figured out what to do in the future, didn't know whether he should accept it or not.

On the contrary, Ye Gongchao, who was by the side, was very interested, and chatted with Yan Renguang a few more words on this topic.

……

After seeing off Yan Renguang, Chen Muwu welcomed a new guest in Cambridge.

Under the guidance of Bridgman, Ye Qisun of Harvard University finally completed a thesis measuring the effect of hydrostatic pressure on the magnetic susceptibility of ferromagnetic materials and obtained his Ph.D.

After graduating, he decided to take a European route, visiting universities, laboratories, and museums in countries such as Britain, France, and Germany, and then decided to take a boat from the port of Marseille or take a train on the Trans-Siberian Railway to return home.

It is much more convenient to read European physics journals in the United States than China in East Asia.

As mentioned earlier, when Ye Qisun was still writing his graduation thesis at Harvard in January, he was called into the office by Professor Du An and asked if he knew a Chinese named Chen Muwu.

And when he read the third and fourth papers published by Chen Muwu in the Journal of Natural Philosophy in July, and saw his mailing address, Ye Qisun learned that this blockbuster genius compatriot should have entered the University of Cambridge.

So before leaving the United States, Ye Qisun wrote a letter to Chen Muwu, saying that he would visit Cambridge University soon, so he took the liberty of writing such a letter, hoping that Chen Muwu could give him some convenience.

For this veteran of physics, Chen Muwu is very willing to do his best to help.
