Marie Curie suddenly remembered a long-awaited incident from seven years ago.

In 1921, the French mathematician Ban Lewei, who had been president of the Council of Ministers of the French Third Republic, led a delegation to visit China, and was awarded an honorary doctorate by the University of Shaojing, introduced to her mother, Marie Curie, a Chinese named Cai, who was said to be the president of a university in Shaojing.

Mr. Cai invited his mother to visit China in the summer of that year, but her mother refused on the grounds that she was going to visit the United States in the summer and that she would not have enough time to go to China during the summer vacation.

Mr. Cai also invited Marie Curie to visit China the following year, in 1922, if she had time, but this invitation did not come to fruition.

Irina, who was in her early twenties at the time, also felt that it was better to go to the richer United States than to go to China.

But now she finally knows how naïve she was at that time.

It is true that the United States is better than China, but that United States does not have Chen's brother-in-law.

If his mother had gone to China before Einstein and brought Chen's brother-in-law to Paris, then those honors should not have belonged to the Cavendish laboratory, but to their institute of radium.

Maybe it wasn't Zhao Zhongyao and Cockcroft who won the Nobel Prize in physics in December last year, but her and her husband, Yorio!

Why didn't he persuade his mother well?

Rather than complaining, Irena was thinking about this thing more like venting a kind of regret.

After all, she couldn't have invented a time travel machine, and it was impossible for her to go back to 1921 and stop her mother, Marie Curie.

And even if she returned to 1921, Marie Curie still had to go to the United States.

The time she went to the United States, she did not agree to give lectures in the United States to earn scholarship fees.

In fact, Marie Curie went to the United States this time, and there was another cause and effect.

That is, in 1920, the year before, she had been interviewed by an American journalist, Madame Mironnay, who had traveled thousands of miles from the United States to France to conduct an interview with Marie Curie, then director of the Institute of Thunderology at the University of Paris.

When Marie Curie was asked if she had anything she wanted to buy, she replied that it was one gram of radium, because although she had discovered radium, she had also published the method of extracting radium to the world, and had not applied for a patent for it, and charged a large amount of royalties.

As a result, although Marie Curie was the discoverer of radium, she could not afford to buy a gram of radium worth $100,000 in 1920.

After the interview was reported by American journalists, it caused an uproar in the United States.

In the end, it was the American people who collectively raised $100,000 to buy a gram of radium from a radioactive company in the United States.

Marie Curie took her two children, Irena and Eve, across the Atlantic to the United States in 1921, to receive a gram of radium from the Americans as they had given her.

Because of this, even if Irena did invent the time machine and go back to 1921, seven years earlier, there would be no way to stop her mother, Marie Curie, from giving up going to the United States and going to China in the East.

After all, at that time, for Marie Curie, the temptation of a gram of radium was far greater than that of a hairy young man whose name was unknown in the East.

Irena can only comfort herself, it doesn't matter, at least now, she and her husband are engaged in scientific research with Chen Muwu.

In the future, Dr. Chen will become their family, and the opportunities to meet each other and engage in academic exchanges will only increase, and will never become less and less.

Moreover, the academic life of this genius Chen brother-in-law will not come to an abrupt end in 1928, but will continue to shine like the sun overhead.

As long as she follows him in physics research, then sooner or later she and her husband Frederick will get the results of their research.

And after arriving in Stockholm again, Irena made a new discovery.

She feels that although Sweden is located in Northern Europe, the overall level of development is not as good as that of her home country, France.

But at least in the suburbs of Stockholm, the Prince's College has a wide range of facilities, and it is not even inferior to the University of Paris.

The only thing that the latter has to say better than the Prince's College is probably the long history of the University of Paris.

Moreover, in the physics laboratory building specially built for Chen Muwu by the Prince College, whether it is the instruments and equipment, or the space of the rooms, it is much better than the Radium Institute in Paris.

Excluding the emotional factor that the Radium Institute was founded by her mother and where she grew up, Irena felt that she had to choose between the two, and she would not hesitate to choose to do research at the Prince's College in Stockholm.

Irena had already decided one thing, when he and Frederick finished their research here in Chen Muwu this time, and returned to France from Sweden, they must go home and persuade their mother to take Eve with the two of them, and give up the Radium Research Institute, which was underfunded every year and relied on the dismal operation of the whole family, to transfer to the Prince's College in Stockholm.

Because everyone has already had the experience of assembling a fifteen-centimeter cyclotron model before, so this time for this standard version of the cyclotron, all we have to do is to put them together according to the previous method of putting together the model.

The only difference is that the fifteen-centimeter cyclotron model only needs to be done yourself.

But this time, when the radius of the cyclotron was extended to 60 centimeters, the five people from the Prince's College used a simple crane.

Because they had already had a lot of experience assembling electrostatic particle accelerators, and because the theory of cyclotrons was already well developed, and they had built a model for testing before, they basically encountered no difficulties this time.

The only thing is the electric field between the two parallel plates of the D-box, because the direction of this electric field is constantly changing, and the frequency of the change is related to the speed at which the particles move in a half-circle around the D-box.

Therefore, they could not directly use the alternating current with a frequency of 50 hertz from the local power plant in Stockholm, and they needed to manually develop a set of frequency conversion devices.

Three stinkers can top one Zhuge Liang, and the three Nobel laureates in physics get together, and two of them have undergraduate degrees as engineers, and it's easy to do this.

While everyone was conducting research on cyclotrons at the Prince's College in Stockholm, earth-shaking changes were also taking place in China in the eastern part of the Eurasian continent.

Chen Muwu's good friend, when he passed through the Northeast by train last time, Zhang Shaoshuai, who had warmly entertained him, this once high-spirited noble son, suffered the first major blow in his life.

Seeing the successive victories of the Northern Expeditionary Army, Zhang Shaoshuai's father Zhang Dashuai could no longer sit in Shaojing City, and could only escape by train on June 3, and after leaving Shanhaiguan on June 4, he was blown up by the explosives that had been buried here on a section of railroad track that was about to reach Fengtian, and finally died.

After Zhang Dashuai died, his successor was naturally Zhang Shaoshuai, whom he had high hopes for and carefully cultivated.

From a gentleman to a big warlord with an army of hundreds of thousands of people and a rule spanning several provinces, Zhang Shaoshuai was obviously not able to adapt to such a big change in his own identity.

In particular, the situation he is facing at the moment is not optimistic, there is a new government in the south that is eyeing the places he rules, and in the east there is a bad intention towards the entire three eastern provinces, and he has become his father's enemy.

Zhang Shaoshuai was caught between these two major enemies and was in a dilemma.

Moreover, these two enemies of his have never given up on winning over Zhang Shaoshuai.

Anyway, Chen Muwu should have known the final result a few months earlier than other people in the world, the Northeast changed flags, and there were no more five-color flags in the entire land of the People's Republic of China, replaced by a new flag with three colors: red, blue and white.

After several years of war, the whole of China has finally reunited in legal terms.

But only God knows what the actual situation is, how many factions are divided among those who carry the same banner, and how many different minds they have.

To say that the big explosion that happened in the summer, as well as the subsequent events, had no impact on him Chen Muwu, it can basically be said that it is minimal.

Dr. Chen is only concerned about two things, one is that he has obtained the two badges from the Beiyang government, and whether he can still lead an annual fee every year in the era of the civil government,—— although the Beiyang government has not issued this money a few times, and has always been perfunctory and in arrears for various reasons.

The second is whether the money he lent to the Swedish Legation can be repaid by the new government and the new atmosphere of the Beijing government.

Chen Muwu wanted to break his scalp, and the only thing he could think of was these two points.

The rest is "what is Dili to me".

In short, Chen Muwu's attitude towards the new government is that everyone knows that there is such a person as the other party, so that's fine.

I don't want to pay attention to you, so you'd better not rush into trouble for me.

Everyone is safe and sound, which is the best of both worlds.

As for wanting Dr. Chen to give the bald man a platform and improve the other party's international prestige?

I advise you not to think so.

During this period of uneven domestic times, foreign countries are singing and dancing.

Although the official opening date of the ninth Olympic Games in Amsterdam is July 28, the competitions of this Olympic Games start as early as May.

The Uruguayan national football team drew 1-1 with Argentina in the final, and then won again in the subsequent play-offs, embroidering a second star on their uniforms.

Hardly any of the five people in the physics lab at Prince College would be interested in a football match at the Olympics.

In addition to Chen Muwu, who was invited by Prince Albert, Duke of York, to Wembley Stadium to watch an English FA Cup match, only Frederick likes to occasionally watch French football when he has free time.

One of his favourite football teams is Parisian club Red Star, which seems to have just beaten fellow Parisian side Selclair to win the French Cup this spring.

The Red Star team should be regarded as a relatively strong club in French football during this period of time, and the annual French Cup championship is either to Red Star or to Marseille.

One of the founders of the Red Star Club was named Jules Remet.

He later became president of the French Football Association and was also elected as the third president of FIFA.

During his tenure, FIFA began hosting the World Cup, and the number of countries involved grew from 21 before he took office to 85.

In recognition of his contribution to FIFA's development, the first World Cup trophy was named the "Remet Cup" before the Hercules Cup – of course, this trophy was also cast by a carver himself, and is permanently retained in Brazil, the three-time World Cup winner.

Unfortunately, the trophy was stolen in Brazil, and its final destination remains a mystery decades later.

The reason why Chen Muwu knew the name of the Paris Red Star team, in addition to Remet, also remembered another thing, that is, the football king who was later called Li Huitang in China once received an invitation from the Red Star team after participating in the Olympic Games in Europe.

Thinking of Li Huitang, Chen Muwu began to think about it again.

Or else he also pulled up a team in England and invited those domestic football kings to come over?

Let everyone train in England while looking for a chance to participate in the Olympics or the World Cup?

At present, the universities in China have a high level of enthusiasm and participation in football, and the level is excellent enough.

Not to mention winning the Olympics or the World Cup, at least it is easy to enter the finals.

However, this is just an idea that Chen Muwu's head is hot, and it is quite difficult to really do it.

The key is that he can't wait to grow three heads and six arms like Nezha now, otherwise he won't be busy at all, and how can he have time to pull up a football club?

The Englishman Cockcroft is not very interested in the football discussed between Chen Muwu and Frederick, and as a traditional Englishman, he prefers cricket and golf.

As time progressed, the construction of the cyclotron at Prince's College was in the final stages.

At the same time, the first phase of the project on the campus is also under construction, and it is about to be announced that it will be completed and put into use.
