Lu Bicheng served tea to the two of them.
Liang Qichao said: "Thank you, Mrs. Li." 33
Lu Bicheng quickly said: "I'm not."
"No?" Liang Qichao understood immediately, "I understand. I heard the news. You have been to Europe together, and now you have come to the United States together. It is just a loss of status. In the future, if you don't mind, I, Liang Qichao, can also be a witness. .”
"I..." Lu Bicheng didn't know what to say and put down the tea bowl, "You guys use it slowly."
Then he turned around and ran away.
Liang Qichao said to Li Yu: "Brother Shucai, you really know how to enjoy taking beauties around."
Li Yu laughed and said, "I still have to sign a contract with Collins Publishing House."
Liang Qichao said: "That one from Star Wars? I've seen it, it's really interesting."
During the conversation, Konoe Aki walked in with a telegram: "Sir, there is another telegram from Germany."
Li Yu asked: "Germany? Isn't it Mr. Planck who wants to push the manuscript again?"
Konoe Akiyuki said: "It was sent by a man named Carl Siemens."
Li Yu took the telegram and read the content. It turned out that Siemens wanted to purchase and sell radio equipment in Germany, or use Li Yu's patent to produce it on its own and then pay the patent fee.
Siemens was an old acquaintance and built a laboratory for him and Planck.
Li Yu agreed to Siemens' request: "You send a telegram back to Mr. Siemens, and I will send a prototype first."
Konoe Akiyuki said: "Sir, please see if you can write it like this. I have learned that I initially agree with your request and will mail a prototype to your place in the near future."
"Okay, just send it like this," Li Yu said, adding, "Tell him that the patent certificate from the US Patent Office will be mailed to him as well."
Konoe Akiyuki was happy to do this work and turned back to the telegraph room.
Liang Qichao took a sip of tea and said, "Brother Shucai, you are now a leader of the new school. You must know how to be monogamous!"
Li Yu was surprised: "How am I a new leader? What does Brother Zhuo Ru mean by this?"
"Of course you are the leader of the new science. Even Gu Hongming and Yan Shenggong Kong Lingyi can't argue with you. What's more, your achievements in science have shocked the whole of Europe and the United States." Liang Qichao blew the tea leaves and continued, "Now these two Both girls are young, beautiful and talented, and they are rare. Although I know it is difficult to choose, brother, I have been here before, and you must understand the meaning of 'giving up', otherwise there will be endless troubles."
Of course Liang Qichao always insisted on monogamy, but he secretly took a concubine, but he never brought it out or told others.
But the concubine gave him six children, so it was impossible for outsiders not to know that he had a concubine.
As a modern person, Li Yu had a deeply ingrained idea of monogamy in his mind. He did not need to tell others about it. He took it as a matter of course and did not say it. He did not expect that in the environment of the late Qing Dynasty and the early Republic of China, others would misunderstand it no matter what. .
Li Yu could only say: "I must adhere to the system of monogamy."
"Okay," Liang Qichao put down the tea bowl, "the decision is not easy, but once the decision is made, I can be the witness."
Li Yu was stunned, why did he really like to be a witness at a wedding?
He knew that Xu Zhimo asked him to be the witness, but Xu Zhimo and Lu Xiaoman were severely criticized at the wedding.
Because he didn’t think the two of them would have a good outcome, because the two of them had an affair within marriage first...
Li Yu smiled and said, "Brother Zhuo Ru, just wait and see. I, Li Yu, will do what I say."
"You have courage!" Liang Qichao pointed to the telegram and asked, "Who is Siemens who sent the telegram?"
Li Yu said: "Mr. Siemens is in charge of Germany's Siemens and is a leader in the fields of communications and electrical."
Liang Qichao said: "I heard that German technology is the best in the world, many times better than the United States today."
Li Yu nodded: "In fact, it is true."
Liang Qichao sighed: "The United States has become so powerful. I really can't imagine what Europe will be like and what a spectacular sight Britain, France, and Germany will be."
Li Yu said: "If you want to compare them like this, I can only say that they are not much different from the United States, almost the same."
Most people now regard Europe as the strongest, and Americans currently think so too.
Liang Qichao really didn't believe it: "Why can England and France dominate everywhere but never heard of this happening to the United States?"
Li Yu said: "Because the United States rose late, but it doesn't matter if it is late, we will rise sooner or later."
Konoe Aki has finished sending the telegram and came out to report to Li Yu: "I have already sent the telegram and it should be received soon. In addition, do you need to contact Count Zeppelin about the airship?"
She really wanted Li Yu to send more telegrams. After all, valuable information could be obtained quickly through telegram exchanges.
Li Yu shook his head: "They will naturally come to me if they need it."
He didn't want to waste too much energy on these things, he still had a lot of things to do.
Liang Qichao asked: "What about the airship?"
Li Yu gave him a general introduction: "It is an aircraft that can bring people, cargo and even bombs to the sky."
Next to him, Konoe Akiyuki's long eyelashes trembled slightly, "Bomb!"
Sure enough, it has something to do with the military!
Liang Qichao sighed: "Do the Germans really have a different structure, which is just like the theory of evolution and is even more outstanding?"
Li Yu quickly corrected him: "Brother Zhuo Ru, everyone is the same, but they only hear the truth first."
Liang Qichao was immediately relieved: "Yes, think about it, you are a Chinese after all, and you are even the strongest in science. Now I finally understand why the "Declaration" is trying so hard to promote you. It is indeed necessary to improve your self-confidence. "
Li Yu said: "Confidence must of course be established. In the future we will also have industries similar to those in Europe and the United States."
Liang Qichao said: "You are right. After traveling in the United States for more than half a year, I finally understand that the era of iron-blooded competition will pass. The future is an era of industrial competition. The key to prosperity is whether we can make profits in business wars."
The trip to the United States greatly shocked Liang Qichao. He was originally based on agriculture, but now he has changed rapidly. In an article, he even likened industry and commerce to "the strength and weakness of a country are determined by this, and the impending death is also determined by this."
Li Yu summed it up for him: "Behind industry is technology and education. Their combination is the way to rejuvenate the country."
Liang Qichao agreed very much and said: "Brother Shucai is indeed not a man of limited talent and learning. I heard that the imperial court has just established a Ministry of Commerce and issued a decree to reward outstanding merchants with official titles. I think you can definitely get it."
Li Yu didn't take it seriously: "But it's just something I'm not interested in."
After visiting the laboratory for a while and explaining some patents, Li Yu mentioned something about Columbia University: "Columbia University in Manhattan is a top university in the United States. There is a Sinology lecture there. I hope you can give a lecture."
Liang Qichao did not object: "It just so happens that I am going to this university to give the teacher's check to Miss Kang."
"Miss Kang?" Li Yu asked.
Liang Qichao said: "Yes, the teacher's daughter Tongbi is studying at Columbia University."
Liang Qichao had three academicians in one discipline, and all nine of his sons were talented.
As for his teacher Kang Youwei, the two daughters Kang Tongbi and Kang Tongwei are considered to be the few outstanding children among Kang Youwei's children. The two came to Columbia University's Barnard College, which is Columbia's exclusive women's college.
Since then, the United States has been known as the famous "Seven Sisters Women's College". Later, only Vassar College and Harvard's Radcliffe College began to recruit male students, and the rest still only admitted female students.
Liang Qichao first gave her a check for five thousand US dollars: "The teacher said that he may travel to Europe in a while, so you should not follow him and go to school in the United States first."
Kang Youwei will stay in Sweden for a long time after traveling through Europe. I wonder if he will buy another island.
As living expenses, US$5,000 was quite extravagant in the early 20th century. The best factories such as Li Yu offered a salary of US$5 a day, which is about US$110 a month excluding weekends, which is only more than US$1,300 a year.
This is still a higher income.
Kang Tongbi took the check and asked, "How is father lately?"
Liang Qichao said: "Don't worry, everything is fine, teacher."
Kang Tongbi looked at Li Yu who was standing aside: "Are you Li Yu?"
Li Yu nodded: "That's right."
Kang Tongbi whispered to Liang Qichao: "My father doesn't like him, don't you know?"
Liang Qichao said: "It's just a personal preference, but Mr. Li Yu is indeed a great talent. This time we were invited to attend the lecture at Columbia University."
It is not easy to give lectures in American universities. Although Kang Tongbi knew Li Yu's abilities, he was unwilling to accept his previous exposure of his father's shortcomings.
Li Yu was too lazy to waste any time and came to the main campus of Columbia University after the handover.
Columbia University President Seth Low, Carpentier, and Ding Long came to greet them, as well as Shade, the first lecturer of the Ding Long Lecture.
Li Yu and Liang Qichao are both super famous Chinese people now. Today's lecture not only attracted many students from the School of Liberal Arts, but also came from the Department of Science at Columbia University, filling the lecture hall with three floors inside and three outside.
Schade is a German and one of the most well-known sinologists in Europe and America in the early 20th century. He has been in China for nearly 30 years. Not only does he speak Chinese fluently, he also has extensive research on Chinese art history, characters, and art.
Moreover, this person wrote prolifically and did research well, and was highly respected in the Western sinological circles. They called this period the "Xia De Era".
Xia De said happily: "It is a great honor to invite two outstanding Chinese people. I have met Mr. Liang, but I happened to leave the capital the year before last. You became famous in the second year. It is a pity that I could not meet you."
Li Yu smiled and said, "It's a pity indeed."
But I thought in my heart that I was lucky enough because I couldn't travel through time left and right.
Liang Qichao said: "This trip was rushed and I failed to prepare properly."
"All you have to do is talk casually, just talk the talk," Schade said.
Liang Qichao cupped his hands and said, "It's embarrassing."
Liang Qichao has been studying new history, so he gave a comparative speech based on some historical differences between China and the West.
Liang Qichao made considerable contributions in this regard, and was not just engaged in politics.
After Liang Qichao finished speaking, Seth Luo asked Li Yu to also speak about some scientific discussions.
Li Yuneng also talked a lot, so he talked a little about the mathematical principles behind physical phenomena regarding his most sensational recent blackbody radiation derivation and x-ray diffraction experiments.
Once combined with mathematics, no matter what subject, the difficulty will suddenly increase.
I remember that in the early years, many people were still bragging that studying was useless, especially that learning mathematics was useless. The powerful counterargument at the time was that mathematics is the best tool for identifying people who can go further.
In later generations, almost all subjects are inseparable from mathematics, such as those taking postgraduate entrance examinations in economics, accounting or finance. Mathematics is very important.
Even literary research uses mathematical statistics...
Sometimes I really feel that what Pythagoras said more than two thousand years ago, "Everything is number" is not unreasonable.
Even though Li Yu slowed down his pace and wrote on the blackboard, many students from the School of Science in the audience still found it difficult to listen.
——It’s still an old problem. Today’s university education either emphasizes mathematics or physics, but does not integrate them better.
Mainly before Planck and Einstein, the status of theoretical physicists was indeed not high enough.
Fortunately, the two aspects Li Yu talked about were hot topics, and students had some understanding of them, otherwise it would have become a holy book.
Li Yu later found that what he was talking about was too difficult, so he ended it by deriving the three major cosmic velocities.
This content is much simpler, but it also caused many people to have questions.
Langmuir Owen asked: "Academician Li Yu, what will happen if the speed of light is reached?"
Li Yu could only say: "Any object with mass will not reach the speed of light."
Owen continued: "But, I have read your article, and you once mentioned the concept of single photons in Germany. In this case, don't photons move at the speed of light?"
He is really Li Yu's little fan, and he actually read this article that was not very influential.
Li Yu explained to him: "It's very simple, because photons have no rest mass."
The students were immediately confused. One moment they talked about wave-particle duality, and photons are particles; the next moment they said photons have no mass?
There are currently no models of elementary particles, so it's not surprising that they don't know.
A student asked: "Is it possible that the experimental devices used by Mr. Michelson and Mr. Morley were unable to transcend the natural rules of reality? In other words, it was because they were in nature where the speed of light is constant and could only measure This speed?"
Good guy, I actually created a little paradox.
It seems that the arrival of the third mathematical crisis is unjust, and everyone likes to mention paradoxes.
If this question is placed in future generations, it will be obvious to everyone that it is a civilian point of view.
But before the birth of the theory of relativity, it was more insightful for someone to ask this question.
Li Yu explained to him: "The speed of light is different in different media, and according to Mr. Maxwell's formula, it can be seen that the propagation of light does not require a medium, and is not even affected by the reference system. As for the speed of light you said does not change , it is indeed the joint result of experiments and mathematical derivation, or rather it is an experimental result. But you have to know that the experimental results reveal exactly the principles of nature."
Li Yu listed for them on the blackboard the derivation of Maxwell's equations and some physical logic of the Michelson-Morley experiment, such as the aberration of light.
Many people have a misunderstanding that the Michelson-Morley experiment is to search for ether.
In fact, it is not the case. The existence of ether was acquiesced from the beginning of this experiment. The original purpose was to test whether ether would interact with ordinary matter.
But the final result denied ether.
It feels a bit like mathematical proof by contradiction.
As for the physical reason behind the constant speed of light, it is unknown. At least before Li Yu traveled through time, humans could not figure it out.
Physics, that's it. Many things are the essence of nature and cannot be explained. We can only continue to explore them from other angles.
The students asked a lot of questions, but if it was in the field of physics, they obviously still couldn't ask Li Yu.
Li Yu once again convinced Columbia students of his ability.
Columbia University is the strongest university in New York. They are convinced that no other school in New York can question Li Yu's true ability. The transcoding has been serious recently, which makes us more motivated and updates faster. Please use your little hands to exit the reading mode. Thanks
Some people died, but not completely...
