Milan's most famous landmark is of course the largest Gothic church in the world, the Milan Cathedral, which took five centuries to complete, where Napoleon was crowned King of Italy.

Of course, in the square in front of the main entrance of the Milan Cathedral in this era, people's behavior is quite civilized, and there are no gangs of "thieves" who rely on violence to directly grab things, nor do they forcibly tie the so-called lucky bracelet to your wrist, and then change hands and ask you for a few euros, and you will not let you go if you don't give money.

This is more advanced than those "college students" who sell a box of pens for 100 yuan to others under the banner of "college student entrepreneurship", and has risen to the level of forced buying and selling.

Well, there is no Tony Leung who flew to Europe to feed the pigeons and flew back that night as soon as he was in a bad mood.

In addition to the Duomo of Milan, there is another famous building in the city of Milan, which was completed in 1926, the year before Chen Muwu's visit to Italy, that is, the San Siro Football Stadium on the outskirts of Milan.

Later, the stadium was renamed Meazza in honor of Milan's famous legend, and it is the home stadium shared by two Serie A giants, Milan and Inter Milan.

Chen Muwu suddenly thought, at this time when he came to Milan now, could he see Meaza representing Inter Milan on the green field?

But after consulting the tour guide around him, he learned another fact about football.

Nowadays, Italian football matches are divided into regions.

The regional champions are determined and then the champions are organized to compete against each other, and the winner becomes the Italian champion of the year.

The Serie A format of organizing eighteen or twenty teams to organize round-robin matches in home and away games and relying on a season's team points ranking to compete for who is the champion and runner-up, and who is the unlucky person who is relegated to the next league has not yet appeared.

In the United Kingdom, Chen Muwu had already watched the FA Cup final a few years ago, and when he came to Italy, his desire to watch a small World Cup could not be satisfied.

Even in this era, there was no World Cup, and it was not until three years later, in 1930, that Uruguay on the South American continent hosted its first World Cup.

Just as the centenary of the modern Olympics did not return to Athens, the centenary of the World Cup did not return to Uruguay and chose to pay tribute in a very comical way.

Atlanta is more commercial than Athens, and Europe is more profitable than South America, which is the key reason why the organizing committees decided to host the event.

Yes, Chen Muwu did not come to Milan alone this time, and he was lucky to have a national tour guide who could not speak Italian, that is, Fermi, who was mechanically memorizing the words of the tour guide on the shore of Lake Como a few days ago.

Fermi, who is a professor of theoretical physics at the University of Rome, came to the Como Conference, partly as a representative of young physicists from Italy, but also because of his multilingual ability to communicate with physicists from other countries who were able to return to the conference.

Now that the meeting is over, there is no point in him staying in Como.

But Chen Muwu did not specifically invite Fermi to Rome with him, and the two met by chance when they got off the platform of Milan's central railway station.

Because he heard Chen Muwu say that he still had to stay in Milan and wait for Hubble, and then go south to Rome together after the two of them converged, Fermi also took the initiative to ask Ying to stay.

He not only took Chen Muwu to the popular attraction Milan Cathedral, but also went to the Church of Our Lady of Grace, which is not far from here.

Compared to the majestic Duomo of Milan, the Church of Our Lady of Grace, which began construction almost a century later, is much more modest.

After arriving in Milan, Chen Muwu visited two churches one after another, not to urgently make up for his religious knowledge before meeting the old man of the Pope.

Rather, it is because in the humble building of the Church of Our Lady of Grace, there is a world-famous painting, the famous mural painted by Leonardo da Vinci on the wall of the church restaurant, "The Last Supper".

Although the mural of the Last Supper is also famous, it is not the painting that first comes to mind when people think of Leonardo da Vinci.

Leonardo da Vinci's world-famous masterpiece is, of course, the Mona Lisa, which is in the Louvre Museum in Paris, France.

In this respect, Italy is similar to China today, that is, the national treasures of its own country, but many of them are stored in museums of other countries.

It's no wonder that people have always said that Italy is the middle of Europe, and the reason why everyone can say this is not only that the football teams of these two countries cannot enter the World Cup.

However, in the 20th century, the Mona Lisa, which hangs on the wall of the Louvre, was once stolen in a strange way.

It disappeared from the Louvre in 1911 and was not reappeared in Italy two years later, in 1913, when the painting Mona Lisa reappeared.

The truth of the matter gradually became clear, and it was an Italian painter from the Louvre, Vincenzo Perugia, who took advantage of the closing time of one day to secretly remove the painting from the wall and transport it back to Italy from France without knowing it.

Perugia declared in the newspapers that he had gone through great hardships to welcome back the national treasure for the sake of his country, and became Italy's national hero at that time.

In the end, he was sentenced to six months in prison, which was a very respectful and light sentence for Italy, which had not abolished the death penalty at that time.

As for where did the world-famous painting "Mona Lisa" end up?

Three years earlier, in 1924, when he was participating in the Olympic Games in Paris, Chen Muwu had entered the Louvre Museum in the company of de Broglie and saw the original painting with his own eyes, which can already explain everything.

This is because after the Italian government obtained the lost "Mona Lisa", it urgently negotiated behind closed doors for two days and two nights, and finally decided to "return the painting to its original owner".

Although Italy was already a member of the "Eight-Nation Alliance", it was one of the great powers that had concessions in the Qing Dynasty and the land of the Min.

But in the face of France, a power stronger than itself, Italy could only choose to bow its head again.

It is also said that the painting "Mona Lisa" was not ranked first in the works of da Vinci or in the collection of the Louvre, but it was only because of this "lost and recovered" theft case that it became famous and became a world famous painting.

The Mona Lisa abroad is kept in the Louvre, while the fresco "The Last Supper" left on the walls of the Church of Our Lady of Grace at home is even worse than the Mona Lisa.

It is said that the paint on the walls began to crack the year after da Vinci completed the painting.

Later, the lazy monks in the church, in order to make it easier to enter and exit the dining room, opened a small door in the frescoed wall of the dining room, which led directly to the kitchen of the church.

Then Napoleon's France invaded and occupied Italy, and the church of Our Lady of Grace became a garrison for French troops, and the church's dining room became a stable for the horses.

The soldiers didn't care who was da Vinci, who was Jesus, who was Judas, who was the eleven remaining disciples.

The painting "The Last Supper" painted on the wall just became the object of everyone's boredom.

They used the faces on the mural as targets for throwing stones, and whoever threw them accurately and hit them more often won more cheers.

The country of Afghanistan blew up the Bamiyan Buddha, which can also be said to be a difference in religious beliefs.

But the French soldiers stoned Jesus in the face, which was somewhat ......

After the French left, the city of Milan also organized people to repair the "Last Supper", but the results can only be said to be better than nothing.

The original Da Vinci paintings that Chen Muwu saw on the walls of the Church of Our Lady of Grace were much more ugly than the photographs he saw in his art textbooks.

As for the use of light and color in the painting mentioned in the book, I'm sorry, I can't see it at all.

Within a day, Fermi took Chen Muwu to Milan for a sightseeing tour of the city, briefly browsing several well-known local attractions, and they waited for the belated Hubble.

Hubble came to Milan by train from Braque, the capital of Czechoslovakia.

Prague was the last stop on his tour of the Holy Land of Europe, where the great astronomer Tycho, who wore a fake nose, spent the last part of his life.

Tycho also took in a student with whom he did not have a good relationship, Kepler, who was also a great astronomer who inherited his mantle.

Because Chen Muwu once quoted Hubble's observation data at the Nobel Prize ceremony.

So although he is not well received in the United States, he still has a certain reputation on the European continent.

After receiving Hubble on the platform of Milan's central station, Chen Muwu introduced him and Fermi, two future best friends, to each other.

Hubble didn't have time to visit the city's attractions, so they had to take a coffee and a panatoni to get on the train to Rome after a quick coffee and a panatoni.

During the Como Conference, one of the questions that impressed Fermi the most was not the particle accelerator brought by Chen Muwu, nor the theoretical paper on two-character mechanics jointly published by a group of young physicists, but the question of "do aliens exist?" that Chen Muwu threw out in order to prevent him from reciting the words of the guide.

After parting on the shores of Lake Como that day, Fermi had been eager to estimate a number of how many planets like Earth in the Milky Way where humans lived.

However, as a theoretical physicist, he did not know much about astronomical data, and second, he did not have easy access to literature in the resort town of Como, so Fermi never made progress in this area.

He had planned to wait until he returned to Rome to look up specific data in the university library.

However, when he heard that Chen Muwu would be waiting for an astronomer from the United States in Milan, Fermi felt like he was sleepy and someone handed him a pillow, so he decided to ask Hubble about the problem directly on the train.

As soon as he settled on the train, Fermi showed his enthusiasm, which made Hubble, an American who is also known for his enthusiasm, a little unaccustomed.

And Fermi's first few questions were quite normal, such as "what is the approximate number of stars in the Milky Way" and "What percentage of the probability that there may be planets in a star system"......

But the more it came on, the more bizarre the question that the Italian asked.

"What is the probability that a planet will be able to evolve into life?"

"What is the probability that these beings will be able to evolve intelligent higher beings?"

"How likely are higher beings capable of interstellar travel?"

"What is the average lifespan of higher organisms?"

"Is it enough time for them to go on an interstellar trip?"

……

None of these increasingly perverted questions can be answered by Hubble, but seeing Fermin's inquisitive eyes, coupled with Chen Muwu's saying that he is a good young physicist in Italy, Hubble can only patiently help Fermi analyze it seriously.

Fermi was not the first physicist Hubble met, but he was the first Italian he met.

Could it be that Italians are as out-of-the-box as he is? Hubble, who was talking all sorts of "nonsense", was a little unsure.

Fermi and Hubble chattered in English about all kinds of advanced "cosmological questions" around them, which did not affect Chen Muwu, who was leaning on the back of his chair and closing his eyes to recuperate and think about the problem.

Because here it is not England or France, but Italy on the Apennine Peninsula.

Fermi and Hubble's discussion was already quite quiet, and even in the most expensive first-class carriages, these noble Italian elites did not reduce their voices in the slightest.

Of course, Chen Muwu was not thinking about serious physics or astronomy, but about the inspiration he suddenly got after visiting "The Last Supper" in Milan, whether he could make "The Da Vinci Code" a twentieth century, and then sell it to Penguin Press to earn a manuscript fee.

The railway distance between Milan and Rome is less than 500 kilometers, and it would theoretically take only half a day to complete the journey.

When the train first started, Chen Muwu also talked to Fermi about the punctuality of Italian domestic trains under the new prime minister, to which the latter only laughed and said nothing.

As a result, when it was time on the train schedule to arrive in Rome, the train they were on also happened to stop at the platform of a station.

The station name written on the station room is also written in four Latin letters, and the last letter is still "a", but the first three letters are still a little different from "Rom".

"Professor Fermi, is the Latin alphabet used by you Italians different from that of the British? Does the letter 'R' in the name of Rome also carry that pinch? Or do you write it as the letter 'P' in English? ”

Chen Muwu asked Fermi confused, he simply put his head in front of the train window and followed Chen Muwu's gaze.

"Dr. Chen, you're really making a great joke, it's not Roma here, it's Pisa."

Pisa, where the legend says Galileo threw the iron ball, is also the seat of Fermi's university.

Hearing him say this, Chen Muwu looked out of the car even more energetically.

Fermi once again saw through Dr. Chen's intentions and told him that the Leaning Tower of Pisa was on the other side of the carriage.

As a result, when Chen Muwu turned his head, he found that the window on the other side of the carriage was completely blocked by a train, and his desire to look at the Leaning Tower of Pisa from afar was in vain.

The whole journey was only halfway through, Chen Muwu couldn't support it anymore, he was so sleepy that he lost consciousness and fell asleep.

This gave Fermi plenty of time to calculate the probability of alien existence on the train.

The three of them left Milan after an early breakfast in the morning, but it wasn't until the sky was full of stars that they reached the capital of Italy.

After being shaken awake in his sleep, Chen Muwu finally saw the word "Rome" on the platform and prepared to get off the train.

But Fermi, who woke him up, said something else.

"Dr. Chen, Dr. Chen, I've figured it out, aliens, aliens, should exist! Shouldn't we write a paper together to announce this contradiction to the people of the world? ”

Thus, the Fermi paradox was calculated on the train more than 20 years in advance – perhaps it should be called the "Fermi-Chan paradox" now.

Chen Muwu, who had just woken up, was reluctant to talk more, but only vaguely agreed to this matter.

"But I don't think any physics journal would be willing to publish such a ridiculous conclusion if you wrote a paper, even with my name. I suggest that when you arrive in Rome, you find the most famous newspaper in Italy and tell the journalists what you find – that's what they love to hear. ”

Hubble, who had also just woken up, stared at the two young men beside him with extremely incredible eyes.

That Italian named Fermi went crazy, and it was okay to say that aliens might exist, Dr. Chen, what kind of madness are you going to go with you!
