Professor Einstein's wish was frustrated.

He read the inaugural issue of the Journal of Prince College in its entirety, except for two papers on the discovery of chemical elements.

Einstein didn't expect Chen Muwu to hide in Stockholm silently and get out of a big job all of a sudden.

Although his main focus was on the study of the theory of relativity, Einstein also paid attention to developments in experimental physics.

He knew that there was another particle in the nucleus besides protons, which had been searched countless times by experimental physicists around the world, but for nearly a decade, no one knew where this particle was.

Chen Muwu only went to Stockholm for more than half a year, and he not only discovered neutrons, but also piggybacked on the positrons released from nuclear reactions.

It seems that physics is not a difficulty at all in other people's places and on Chen Muwu's side, others have tried hard to find it, but everything comes easily to him.

Albert Einstein didn't know exactly what the discovery of the neutron meant.

Perhaps not only Einstein, but physicists all over the world probably believe that the discovery of neutrons only solved the problem of what is in the nucleus of an atom except protons.

If you want to further improve the status of neutrons, you have to wait until the chain reaction is discovered.

At that time, the neutron will change from a harmless "elementary particle" to a world-destroying weapon.

Einstein failed to find new evidence to refute quantum mechanics from several of Chen's papers.

But he still wrote a letter to Chen Muwu, the content of which was not to criticize quantum mechanics as wrong, but to congratulate him on his new achievements in experimental physics.

It's a pity that Einstein's letter was sent to the Prince's College in Stockholm.

Chen Muwu, who is currently in Italy and is about to return to the UK to get married, wants to see the content of this letter in person, and he will have to wait for a long time.

Physicists at universities and institutes on the continent have made their own "critiques" of the contents of the inaugural issue of the Journal of the Prince's College.

But across the Atlantic Ocean in North America, the physicists at those schools had just received the inaugural issue from Stockholm.

Of course, they received the journal Nature much later than on the European continent.

Only a small number of physicists received telegrams from their European counterparts in advance, and only then did they know that neutrons had been discovered by Chen Muwu in Stockholm.

Oppenheimer of the University of Chicago apparently belonged to the group that did not receive the telegram.

It stands to reason that Chen Muwu should be blamed for this matter, when Oppenheimer left Cambridge University and returned to the United States to teach, Chen Muwu promised him that he would get in touch with him as soon as he had any academic achievements in the future.

And the discovery of such a big thing as the neutron is, of course, an academic achievement.

But Chen Muwu forgot his previous promise, probably because he was going to send too many people in Stockholm at that time, so he completely forgot about Oppenheimer.

Previously, Chen Muwu founded the Journal at Prince College, and this news was that Compton, a colleague at the University of Chicago, read the news from the Chicago Tribune.

At that time, Oppenheimer felt that Chen Muwu might be busy in Stockholm, and this was not an academic achievement, so he didn't pay much attention to Chen Muwu's newspaper.

But this time it was completely different, the discovery of neutrons was a big deal for all physicists, and Chen Muwu not only discovered neutrons, he also discovered positrons, invented cyclotrons, and discovered two new elements.

Each achievement alone is a remarkable achievement in experimental physics.

Even if Chen Muwu may forget it once because he is very busy with work, he won't forget it every time, right?

Did he forget, or did he deliberately not send a telegram to himself?

Oppenheimer really couldn't say anything about it.

He felt that he could not stay silent at the University of Chicago all the time, even if he did not leave the United States and return to Europe, at least he had to have a relationship with Chen Muwu, write a letter to him, and make Chen Muwu realize that he still has a very loyal right-hand man in the United States.

So Oppenheimer also wrote a personal letter, and Einstein sent the letter to Stockholm in unison.

These two people didn't know that Chen Muwu would not see their letter until a long time later.

But compared to Chen Muwu's reply, both of them received another thing from Chen Muwu's hand at the same time.

Although Chen Muwu is in Bologna, Italy, not London, England.

But the people who were preparing for the wedding in London didn't relax at all.

According to the list left by Chen Muwu earlier, they sent telegrams to each of the friends he had made all over the world.

The contents of the telegram were the same, inviting them to come to London to attend the wedding of Chen Muwu and Eve, if time permitted.

In this year, in addition to using the telegraph to distribute invitations, there is another thing that must be done to get married-

That's in the newspapers.

While radio stations have become more and more popular, television signals are maturing and developing.

But newspapers are still the most direct way for the general public to obtain information, whether it is getting married and having children, celebrating birthdays, missing person notices or someone has died, everyone likes to spend a few shillings or a few pennies to publish a tofu block news in a corner of a certain page of the newspaper.

Don't wonder if anyone will see these messages, the answer will be yes.

The first is that large newspapers have a large circulation and a large number of readers.

Second, in the era when entertainment activities were relatively scarce, many people would carefully read the entire content of the newspaper, even the advertisements.

Otherwise, Hubble would not have spent a lot of money to publish an ad in the New York Times about his academic research at his own expense.

The third is that these ads are much more effective than they should be.

Because in these advertisements and notices, there is a lot of real news, but there are also many untrue news.

Workers in some special industries are very good at using the inconspicuous tofu blocks in the newspaper to convey codes and messages that only they can understand in a small area.

Even more than 100 years later, if someone still wants to publish the news of marriage in the newspaper, they can still spend dozens of dollars to do so.

The major newspapers on Fleet Street in London have received applications from Chen Muwu's family to publish the marriage notice.

This kind of postings and advertising messages are not reviewed by a dedicated editor.

All you need to do is pay enough to select a date for the publication of the news, and the news to be published will be delivered directly to the DTP.

So it wasn't until the typesetting rooms of the newspapers that the word pickers inadvertently discovered the news.

There may be many Chinese in London, but there is only one named Chen Muwu.

Even if this word picker doesn't know Chen Muwu's contribution to physics, he more or less knows that there is a book called "George Chen" series, and knows how popular this book is in the UK, so he has a general understanding of the author of this book, Chen Muwu.

When the word pickers found out about the news, the editors of the London newspapers received phone calls in the middle of the night and learned the news.

The next day, all major newspapers published in London published the news that Chen Muwu was about to get married.

However, it is not reported as news on the page of the usual advertisement, but on the body page of the newspaper.

Cambridge University and even the most famous young physicist in Britain, Chen Muwu, are going to marry the daughter of Marie Curie, who won the Nobel Prize twice, which is a big deal anyway.

And it is said that Dr. Chen has recently had a double harvest in love and career, not only is he about to return with a beautiful woman, but he has also discovered neutrons and positrons.

- The British newspapers did not put much effort into popularizing science, because they thought that even if they did, it was estimated that no one would understand.

In addition to news reports in newspapers, all newspapers and newspapers on Fleet Street have also assigned a new task to their reporters-

That is to see if anyone can get the invitation card of Chen Muwu's wedding, enter the wedding scene, and report first-hand news about the wedding for readers.

Oppenheimer received a telegram from Chen Muwu, which finally calmed his heart a little.

At the very least, this can prove that Mr. Chen still thinks about himself in his heart, and maybe the results of the physics society he made do not send a telegram to him, which may be due to his troubles.

Oppenheimer finally had a legitimate reason to go to Europe, although Chen Muwu's wedding date was already the start of school for American universities.

But Oppenheimer took a leave of absence from school, and nothing could stop him from going to Europe.

After learning that Professor Oppenheimer was going to attend Chen Muwu's wedding, Compton happily granted leave.

He also asked Oppenheimer to convey his and the entire University of Chicago physics department's wedding wishes to Dr. Chen.

Oppenheimer was not the only one who received Chen Muwu's invitation from the United States, but Professor Hubble, who had already completed the resignation procedures from the Mount Wilson Observatory, also planned to leave the United States and go to Stockholm, the capital of Sweden, to develop by Chen Muwu's side.

Although the astronomical equipment of Prince College is still basically in the drawing stage, Professor Hubble has made a strong determination to leave the American astronomical community controlled by the Academy.

He is even more eager to design and build an observatory according to his wishes, and although he may waste several years of scientific research time, he will definitely gain a rather relaxed and free academic research environment.

And Chen Muwu has also promised Hubble that if he wants to make astronomical observations, Chen Muwu can use his status as a dual fellow of the Royal Society and the Royal Astronomical Society to help him contact the Royal Observatory Greenwich in the United Kingdom, so that he can use the astronomical telescope there to observe the starry sky.

Hubble, who received Chen Muwu's wedding invitation, saw it as a perfect opportunity to leave the United States.

So he packed his bags for a while, and first took a train from the western United States on the Pacific coast, across the entire North American continent to the eastern United States on the Atlantic coast, and boarded the same transatlantic ship as Oppenheimer.

In addition to the two of them, other scientists in the United States who received the Journal of Prince College but did not receive Chen Muwu's wedding invitation began to follow in the footsteps of their European colleagues.

Everyone can either replicate Chen Muwu's experiments and discover neutrons and positrons in their own laboratories.

Either that, as Zhao Zhongyao and Cockcroft described, began to measure the precise mass of neutrons.

But neither American experimental physicists nor European experimental physicists have replicated two of these experiments.

One is to bombard the bismuth metal target with accelerated alpha particles to obtain the No. 85 iodine-like element, and the other is to bombard the metal molybdenum with the accelerated deuterium nucleus to obtain the No. 43 element manganese.

This is because although they have seen what a cyclotron is on the cover of the inaugural issue of this issue of the Journal of Prince College, they have never seen the actual thing, and can only guess based on their own feelings, it seems that this new thing built by Chen Muwu is more advanced than the one they bought from the Cavendish laboratory at a large price.

Some bold physicists have tried to use electrostatic particle accelerators to replicate Chen Muwu's two experiments in discovering new elements.

However, one of the major disadvantages of electrostatic particle accelerators is that after every few bombardments, the potential difference transmitted to the electrodes through the charge conveyor belt is exhausted, and the electrodes need to be charged again before they can continue to bombard.

Using this particle accelerator, it may be possible to reproduce the experiment of deuterium nuclei bombarding metal molybdenum, because the obtained element 43 manganese-like has a long half-life and will not decay in the process of charging the electrostatic starter.

However, the 85th element iodine, which has a half-life of only a few hours, is different, and during the time when the electrodes are recharged, many iodine-like iodines have begun to decay externally and return to the metal bismuth.

Some people also began to send telegrams to Chen Muwu according to the address left in the "Journal of the Prince College", asking for the price of the cyclotron, hoping to buy it from the Prince College and install it by them, just like the electrostatic particle accelerator before.

American physicists, doing experiments, taking a boat to Europe to attend Chen Muwu's wedding.

At this time, Chen Muwu, one of the protagonists of the wedding, had already crossed the Alps by train and came to Bologna, Italy.

Why do you think I'm a physicist, so why did I come to the International Congress of Mathematicians?
