Lying on the bed after eating and drinking, Chen Muwu wrote up the manuscript for the topic of his next lecture.

In fact, this kind of lecture on the theory of relativity is also very simple, and today's Chinese people respect the theory of relativity, not because they respect the scientific principles in it, but because they praise it for leading a great revolution in physics.

Unlike the strong resistance to the theory of relativity in European and American academic circles, the Chinese people quickly accepted this new theory.

First, because China already had the kinematic idea of the principle of relativity as early as the Han Dynasty, and the concept of "ether" had almost no impact on the intellectual history of modern China.

The second reason is that in 1919, when Eddington was observing a total solar eclipse on the island of Principe in West Africa, the new cultural movement in China was also in full swing.

The total solar eclipse observations were transmitted back to London, and the Times reported with the headline "Scientific Revolution, New Theory of the Universe, Newtonian Thought Overthrown!" 》。

The theory of relativity, an important theory that broke the absolute space-time view of Newton's classical mechanics that had dominated the physics community for hundreds of years, soon became a typical example of breaking the old and establishing the new, and became a banner of "Mr. Sai", rising in the sky above the academic circles.

In 1920, Russell visited China and lectured at the University for a year, during which he vigorously praised Einstein and his theory of relativity, which further contributed to the craze for relativity in China.

For a time, people who knew physics, as well as those who didn't understand physics, wrote articles in newspapers and magazines, all praising this new thing called the theory of relativity.

Even the great poet Xu Zhimo, who had nothing to do with physics, wrote an article entitled "Anstan Relativism, the Great Revolution in Physics", which was published in the April 1921 issue of the magazine "Transformation" with a large number of private goods through popular science.

Whether the content of the article is correct or not, Chen Muwu is inconvenient to say.

- What is there to say about this! It is obviously a theory in physics, but in the title, this guy has given the theory of relativity a philosophical term "ism".

You may say he's wrong, but physics is indeed a natural philosophy; You say he's right, but it always sounds awkward.

These various manifestations in the cultural circles are enough to show how popular the theory of relativity was among domestic intellectuals at that time.

Chen Muwu felt that most of these lectures should be aimed at people like Xu Zhimo, who are vassals and good dragons, and it is okay to talk about simple knowledge, but a little more advanced will make people drowsy.

For example, he can talk about the "Einstein train" in the special theory of relativity, but he must not talk about the "Einstein elevator" in the general theory of relativity, they can't understand it!

Now that such a lecture policy has been determined, Chen Muwu's next topic selection is much easier.

In the end, he settled on five topics, Relativity and Space, Relativity and Time, Light, the Universe, and Time Travel.

As for how to talk about these topics with relish, Chen Muwu is not helpless, the two popular science books "A Brief History of Time" and "The Universe in the Shell" that were sold in later generations will not be published for fifty or sixty years, plus those entertaining and educational "Feynman Lectures on Physics" and "New Concept Physics Tutorial", I have a little bit of it at my fingertips, won't it become his Chen Muwu's "original"?

Of course, be careful not to spoil too much, and not to cite theories and hypotheses that have not yet been generated.

When he woke up the next day, Chen Muwu went to Shaoda again and handed over the note with five topics to Hu Shi.

The lecture is imminent, and the university must also advertise in the newspapers so as to attract more audiences.

Then he went to the library on the first floor of the Red Building, found a place with a clear window and sat down.

Chen Muwu originally thought about whether he could meet the bearded Mr. Shouchang in "The Awakening Age", but only after arriving did he know that the Shao University Library had a new leader at the end of last year, Mr. Li had a new position, and the director of the library was succeeded by Pi Zongshi.

Since he didn't have the opportunity to meet, he took out the pen and notebook he carried with him and listed the outline of the lecture one by one.

When talking about where to tell a joke and where to shake off a burden, he also wrote it one by one.

Writing and writing, Chen Muwu also thought of a cross talk video that he had seen on station A in later generations, "The Guidance and Application of Quantum Mechanics and General Relativity in Cross Talk Performance and Creation".

As a student of the Department of Physics, he and his partner once transplanted this cross talk to the school's New Year's Day party one year, which won the laughter of the audience.

It's a pity that time is tight and he doesn't have time to rehearse, otherwise he would have thought about repeating this cross talk again now.

Perhaps, the little black fat man in the future will also call him a senior.

Unexpectedly, the day before the lecture, there were still variables in Shao Da, and Hu Shi's sworn package ticket became a blank check.

When they met for the first time, he said that Cai Yuanpei's departure from school would not affect the normal progress of the lecture, but on Saturday afternoon, Hu Shi still went to Ma Yuzao's house in Dongbanqiao to find Chen Muwu and told him that because the students had gone to the Ministry of Education to ask Cai Yuanpei to return to school, the number of people in tomorrow's lecture was insufficient.

Hu Shih asked him if he could postpone all the lectures by a week, that is, the first lecture would be scheduled for next Thursday.

Chen Muwu didn't have any consideration for this, saying that he was completely at will.

Hu Shi thanked him for his understanding, and informed Chen Muwu that the travel expenses incurred during his stay in Shaojing would be subsidized by Shao Da.

In fact, there is a shortage of students! It's just that US Minister Shulman suddenly wants to go to Qiandao to inspect the proposal of the Washington meeting on the issue of China's Qiandao, and it is estimated that it will take about half a month.

Calculating the time, if Chen Muwu still lectures according to the original arrangement, then Schulman will not be able to catch up with the game.

I spent a lot of money to invite people, but I didn't hear a single one, no matter how rich you are, you can't squander it like this!

Therefore, Hu Shicai had to use the reason of the insufficient number of students to postpone Chen Muwu's lecture, so that Schulman could catch up with the last one after returning to Beijing.

Of course, Chen Muwu didn't know the real reason behind this, he only knew that he suddenly had half a week more time to prepare, and he didn't know what he should do all of a sudden.

The outline of the lecture has been laid out, and it is neither meaningful nor necessary to continue to write a detailed speech according to the outline, because the content above is extremely simple for him, but he has to deal with the audience who raise their hands to ask questions from time to time, and if the speech is written in too much detail, it will also mess up.

Counting the time, two months have passed since his paper submitted to Europe, and half a month has passed since Einstein's telegram was sent.

I wonder if the paper has been published in a journal? What impact has it had on the academic community in Europe and the United States? Is there more people who support him, or are there more people who scold him?

Just when Chen Muwu had nothing to do, and even planned to write another shocking paper, a childish voice suddenly came from outside the door: "Brother Chen, someone is looking for you outside the courtyard gate." ”
