Kang Youwei in the audience was amazed: "Western drama and dance can be said to have sprouted (started) in China. There are many similarities between the two in body language and customs. Therefore, I think we should call on domestic drama and dance to learn from Westerners."
"
Li Yu was a little irritated by these words of worshiping foreigners, but before he could refute, Bernard Shaw objected first: "Mr. Kang, actually I want to say that your country's operas are more expressive and have many merits.
After all, dance comes from life and from the local area. China and the West can communicate, and if we talk about learning, we should say learning from each other."
After the performance, before leaving, Oxford Vice-Chancellor Bruce gave each of Kang Youwei and Li Yu a commemorative pocket watch.
The pocket watch was of high quality at first glance, and the price was much higher than what Li Yu had bought in Sweden before.
Things made in Europe are indeed remarkable in terms of their exquisiteness.
Kang Youwei praised: "The British utensils are exquisite, but the domestic utensils are much more humble. They are not as good as they used to be!"
George Bernard Shaw wondered: "Nowadays, many of the best luxury goods in Europe are made of porcelain, tea and silk from China. How can they not be exquisite?"
Kang Youwei said: "If it is the utensils of the Tang, Song and Ming dynasties, there are many exquisite ones. But in the Qing Dynasty, they are hard to find. Just like the actors on the stage, many scholar-bureaucrats in the late Ming Dynasty could cultivate excellent actors and actresses, but now, how can they still be found?
Seeing a scholar-official family with an actor? To use a word I learned recently, there is a huge gap between the rich and the poor."
Unexpectedly, he also read Marx and mentioned the "gap between rich and poor". Li Yu thought that he could extend his thinking like Liang Qichao. Unexpectedly, Kang Youwei went on to say: "Exquisite utensils must consume countless unnecessary resources to make them."
.After it is completed, there must be wealthy people with good intentions who love to play and spend a lot of money to buy it, so that the manufacturer can benefit and continue to fight for it. But now that the country is so poor, how can we create exquisite things again?"
Li Yu almost stumbled because this guy directly confused luxury goods and industrial products.
Luxury goods are indeed toys for the rich, but he may not have been to the palace a few times. He doesn’t know that any country actually has many exquisite artifacts. Later generations of African chiefs can drive Rolls-Royce. Good things in the Forbidden City
There are too many to count.
Li Yu reminded: "Mr. Nanhai, you really should read some science and technology books, even popular science articles. It would be really bad if you say the wrong thing in this situation."
Kang Youwei snorted: "The light of a mouse's eyes does not understand the truth."
Luo Chang pulled Kang Youwei and whispered: "Nowadays, the whole of Europe and America highly respects Li Yu. Master, it's better not to speak of him like that."
Kang Youwei's expression changed a little, but he quickly calmed down and said: "He just wants to suppress me in terms of reputation, so that he can secure his title of 'Emperor Master', and then use small businesses to make ill-gotten gains. Have you forgotten that Weng Tonghe and
Is there a fight between Li Zhongtang?"
Luo Chang opened his mouth, not daring to continue speaking.
However, Kang Youwei also understood that he would not be able to debate Li Yu in a Western university, so he said to Luo Chang and his daughter Kang Tongbi: "Let's go, we have to go to European countries to study and travel."
Li Yu was speechless. Kang Youwei still looked down upon industry and commerce, but he didn't think there was anything wrong with his own fundraising.
What brain circuit.
Li Yu needed to continue returning to Cambridge, and Rutherford had already prepared the electroscope.
Then Li Yu and Owen Richardson conducted a lift test in a hot air balloon and recorded changes in different altitudes.
The starting altitude is relatively low, within one thousand meters from the ground, and the amount of radiation is indeed getting smaller and smaller.
Lu Bicheng was so enthusiastic that she wanted to go to the sky together to see it. She also thought it was fun to ride in a hot air balloon.
Li Yu saw that he had preliminary experimental data and went to Thomson, the director of the Cavendish Laboratory, to ask for someone again: "Mr. Director, may I ask if Professor Wilson from your school is available recently?"
Thomson said: "Dr. Wilson are you talking about? He is not a professor yet. He has been in my laboratory for several years before and has a good relationship with Rutherford and the others. Do you have anything to do with him?"
Li Yu said: "One of Dr. Wilson's inventions is very meaningful, and I would like to borrow it from him."
Thomson said: "Yes, but he is not my subordinate now. Wilson became a physics lecturer a few years ago. He should be in the physics department now and should be taking classes at this time."
Li Yu said: "Thank you, director, I will go find him now."
There are definitely not as many students in universities today as there were in later generations. Li Yu saw Wilson who was in class outside the classroom. He was talking on the stage:
"Energy transfers, through work, through heat, energy changes."
Wilson then wrote down several integral equations and continued: "They go in and out of the systems that regulate our lives. These systems interact to seek balance. An ice cube will melt in a hot room, and the energy of this process
The transfer causes entropy to increase. This process, like other natural processes, is irreversible."
However, the Cambridge students seemed to be difficult to deal with, and soon a student raised his hand.
Wilson said: "Eddington, what do you want to say?"
Li Yu was startled outside the house, "Okay, Eddington. This man later became very famous in astronomy. But the most famous thing is one of his famous quotes."
At that time, Einstein had published a more complex general theory of relativity. Eddington was a die-hard fan and preached the theory of relativity everywhere.
Once a reporter asked Eddington: "I heard that there are only three people in the world who really understand the theory of relativity?"
Eddington thought for a while and said: "I am wondering who the third person is."
This joke is widely circulated. Li Yu heard it when he was a child and was deeply affected by it: Newborn calves are not afraid of tigers, so they want to know if it is really that difficult!
This was one of the reasons why Li Yu chose physics.
Returning to the current class, Eddington said: "If heat is the result of molecular motion, and Newton's laws of motion are reversible, then how do you explain what you just said about 'irreversibility'?"
Eddington's question was quite sharp at this time, and Li Yu had time to wait outside to see how Wilson would answer.
Wilson was not in a hurry: "Although there are some obvious signs of the existence of molecules, I want to say that this is a classroom. I can only teach you what you already know. As for how to explore in the future, it is your business.
."
Eddington said: "Then when will you allow us to do the experiments mentioned in Mr. Li Yu's paper?"
Wilson said: "This experiment has a premise, which is that the existence of the molecule must be 100% confirmed. This is the experimental idea to eliminate interference."
At this time, another student raised his hand.
Wilson said, "Mr. Bakla, what's your problem?"
Good guy, it's Charles Bakra again, winner of the 1917 Nobel Prize in Physics.
As mentioned before, Rutherford came to Cambridge on a scholarship, and Bakra was also the recipient of this scholarship.
Two years ago he went to study at the University of Liverpool, and now he is back in Cambridge.
This class is really exciting.
Bachla said: "From a kinematic point of view, Newton's laws of motion are reversible, just like if I scatter a box of pencils from the pencil box to the ground, they will not spontaneously return to the box, but from a mathematical point of view
, but it can be done.”
"Oh!" Wilson felt more and more confused. These students were thinking too fast. "If your question can be researched, I think it will be a good graduation thesis. But I don't know how to answer you now."
A few people were chatting, and it was already time for get out of class to end.
Early European universities sometimes looked like chat rooms.
Professors also like to sit together with students to discuss problems. This is a tradition: in the past, paper in Europe was extremely scarce and parchment was even less, so there were very few books. In a class, only the lecturer might have one book in his hand, so everyone could only
Surround the lecturer to listen and discuss.
Eddington and Bakla were still pestering Wilson. They walked out of the classroom and suddenly saw Li Yu standing by the window.
Bakla was the first to recognize it: "Are you Academician Li Yu?! Oh my god!"
Wilson knew that Li Yu was in Cambridge, but he did not expect him to come to the teaching area. "It is a great honor to meet Mr. Academician."
Li Yu smiled and said, "I'm sorry to disturb you."
Wilson said: "You are here and I can no longer answer their questions. I wonder if Mr. Academician can help me with this."
Li Yu said to Bakla: "Mr. Bakla, you may have to thank the development over the years, otherwise this approach of introducing probability theory into physics will attract many people's opposition. Mr. Maxwell received a lot of criticism back then."
Bakra said: "I have read your talk about the second law of thermodynamics, entropy increase. Isn't it correct? I remember that you used a lot of mathematical derivation, which was very exciting."
Li Yu said: "If we follow the theory of probability, not only pencils can return to the pencil box by themselves, but even a pile of sand can automatically turn into a castle, steel can automatically turn into a train, and ink spilled on paper can even automatically complete homework.
However, due to the principle of entropy increase, this is impossible.
Because this is from disorder to order, that is, entropy decreases.
Mathematics and physics are closely related, but their differences cannot be ignored. After all, physical significance is crucial to physics."
Bakla suddenly realized: "Thank you, academician, for clarifying my doubts. I hope to study and work with you in the future."
Li Yu knew that Bakla was a person with great potential, so he said: "Of course you can. But you must get excellent in the academic examination."
Bakra immediately said: "I can definitely do it!"
Eddington was also shocked by Li Yu's achievements in astronomy: "Mr. Academician, I have read almost all of your articles. I found that your articles not only indicate that mathematics and physics are closely related, but also imply that astronomy and physics are closely related.
Learning has an inseparable inner connection.”
Li Yu smiled and said: "Your insights are very accurate and admirable."
Wilson said from the side: "Mr. Academician is very good at teaching. I think they will be very encouraged by your few comments."
"Whatever they have to do with me is the result of their own efforts." Li Yu said.
"Mr. Academician is indeed as rumored to be, full of Eastern virtues of humility," Wilson said. "By the way, are you going to find Director Thomson? The laboratory is not in this direction."
Li Yu said: "It doesn't matter, I'm just here to find you about your experimental device."
Wilson asked: "Cloud Room?"
Li Yu nodded: "That's right."
Wilson said: "Please come with me."
In Wilson's office, there is an early form of the cloud chamber. Although it is a bit crude, it has been opened up in principle.
Li Yu looked at it and said, "If you can take pictures, it will be more useful."
Wilson said: "You mean, like those telescopes at Greenwich Observatory, which can not only observe, but also take pictures?"
"Yes," Li Yu said, "microscopic things require more photos."
Wilson thought for a while: "I have always regarded it as an instrument for exploring x-rays, and I didn't think too much about it."
Li Yu smiled and said, "Then you must think about it carefully."
Wilson agreed: "I can give it a try, but I need to discuss with the principal to find someone to teach you."
Li Yu said: "If you can't find anyone, I can help you!"
Wilson was also happy: "If the principal hears this, he will definitely not be able to find anyone else to take over."
As Wilson said, Cambridge University "suddenly" couldn't find anyone else to teach physics.
There was no other way. In order for Wilson to complete the improvement of the cloud room as soon as possible, Li Yu could only help him teach.
Anyway, in universities of this era, whether in Europe, America or China, classes are relatively casual, there is no particularly fixed teaching plan, and professors and lecturers have a lot of room for free expression.
(At most, Germany may have introduced militarized management in some universities, which is quite special.)
Professors and lecturers sometimes even study their own topics in class and deduce very cutting-edge theories on the blackboard. It doesn’t matter whether anyone below can understand it...
Um, it seems that the Internet said that this is also the case when Wei Shen teaches mathematics classes?
In fact, in top universities, it is really not surprising. There is no need to ridicule others for their poor teaching standards.
So Li Yu can talk casually at this time.
But this was great, as many students from other majors came over, so the class could only be turned into a seminar.
By the end, even students from Eton College came to listen to Li Yu's lecture.
Eton College has 250 graduates every year, more than 70 of whom can enter Oxford and Cambridge, and most of the others can enter world-famous universities. It is a typical "cradle of elites" in the UK, and has produced 20 prime ministers alone.
Eton College has a long history, and its location is impressive: the small town of Windsor. Windsor was the surname used by the British royal family thereafter.
Originally, this school hoped to allow children from poor families to attend school and serve as a preparatory school for Cambridge University.
Who would have thought that, as aristocratic children rushed to attend Eton College as an honor, by the 17th century, Eton College had become the most famous aristocratic school in the UK, making it once again out of reach for common people.
In later generations, it became recognized as the best middle school in the UK.
Li Yu thought about future generations. It seems that no middle school in the country dares to stand up and say that it is the best in the country. At most, it can be said to be the first.
