Reborn and become a Great Scientist

Chapter 392 131 Another Christmas

"Dr. Chen," Lei Bingyang was moved and excited after hearing Chen Muwu's promise. He was a little incoherent, "Thank you, thank you very much! You have really helped our embassy a lot. Please rest assured that I will I will definitely write you an IOU, and when I have money in the future, I will pay it back as soon as possible. I, Lei Bingyang, will do what I say!"

Chen Muwu smiled on his face, but there was no emotion in his heart.

After he lent the money, he had no intention of recovering it.

Don't you want to?

No, Chen Muwu knew from the beginning that the money would basically never be returned.

Even if, as the charge d'affaires in Sweden said, he wrote an IOU to Chen Muwu.

However, if the other party does not repay, what is the use of just having an IOU?

Could it be that Chen Muwu could still return to China from Europe and go to the Ministry of Foreign Affairs with an IOU to demand the money he owed from the Beiyang government?

Another point is that the Beiyang government is about to collapse, and it is still unknown whether the bald man in the south will admit the debt.

The reason why he prevented Lei Bingyang from borrowing money from the Swedish government was to make China look a little better abroad.

After all, he is likely to live in Sweden for a long time in the future, and he cannot let people with ulterior motives poke his spine every day with this matter.

All in all, it was more like losing money and avoiding disaster.

Chen Muwu didn't bring much money with him when he came to Sweden this time.

And now there are no bank magnetic stripe cards, no visa and MasterCard, no Alipay and WeChat transfers, even if Chen Muwu has plenty of money, he is a small rich man worth tens of thousands of pounds.

Although he agreed to Lei Bingyang's loan, there was still a problem as to where he could quickly raise the money.

It would definitely be unrealistic for him to return to the UK to get money from Lei Bingyang.

So what if you just ask the Swedish Crown Prince or Marcus Jr. to borrow money?

Chen Muwu felt something was wrong again.

In this way, it was still borrowing money from Sweden, but the borrower changed from the Chinese Embassy in Sweden to Chen Muwu, and the lender changed from the Swedish government to one of his two friends.

Fortunately, Chen Muwu quickly found the source of his money.

The total prize money for this year’s Nobel Prize in Physics is less than 130,000 Swedish kronor.

Because three people won the prize together, and the reasons for winning were two different reasons, Wilson, who invented the cloud chamber, got half of it, which is more than 60,000 Swedish kronor.

The remaining half was divided equally between Zhao Zhongyao and Cockroft, and each of them also received more than 30,000 Swedish kronor.

It was this money that Chen Muwu was eyeing, and he planned to borrow the Nobel Prize bonus from someone.

It was difficult for Professor Wilson to speak because he had already invented the cloud chamber before Chen Muwu arrived at the Cavendish Laboratory.

His winning of the Nobel Prize this time can only be said to have some relationship with Chen Muwu, but not much.

The remaining two people all built successful particle accelerators under the command of Chen Muwu. Chen Muwu borrowed money from them without any psychological burden.

Cockcroft is already married and seems to have welcomed a new child this year.

Chen Muwu did not speak to him, but allowed him to remit the money to his home as soon as he received the bonus.

The person he asked to borrow money from was the remaining winner, Zhao Zhongyao, who was currently alone.

Zhao Zhongyao has no family affairs in the UK, and if he remits his winnings to China, he will have to spend a lot of money in handling fees alone.

So he just got a check from the Nobel Prize jury with the amount of the prize written on it, and planned to exchange the check into pounds of equivalent value before leaving Sweden after he and Chen Muwu finished building the cyclotron in Stockholm.

Chen Muwu was eyeing this bonus. Anyway, Zhao Zhongyao was in Sweden during this period and had nothing to spend money on.

So after hearing Chen Muwu's request for a loan, Zhao Zhongyao quickly agreed and gave all the bonus of more than 30,000 Swedish kronor.

In this way, after leaving Sweden and returning to the UK, Chen Muwu could just pay Zhao Zhongyao more than two thousand pounds.

There is no middleman to earn the difference in the loan and repayment between them, and it can also save Zhao Zhongyao an exchange fee incurred when exchanging Swedish krona for pounds in Swedish banks.

After Chen Muwu received the check lent to him by Zhao Zhongyao, he immediately called the Chinese Embassy in Sweden.

Lei Bingyang came to pick it up in person and said many words of gratitude to Chen Muwu.

Although in the next period of time, Zhao Zhongyao and Cockcroft will also be invited by various parties in Sweden to give several lectures to people from all walks of life as the new Nobel Prize winners in physics.

But for Chen Muwu, the Nobel Prize award ceremony is over, and he can return to the physics laboratory at Prince's College on the outskirts of Stockholm to continue his work on the development of cyclotrons.

Because of the help of the Swedish Crown Prince and little Marcus, the factories in Sweden are very efficient.

Within a few days after the Nobel Prize dinner, Chen Muwu and the others received the glass covers they had customized from the factory.

At this point, all the materials for this cyclotron model are ready.

The next step is to assemble them all together to see if the model can run smoothly and whether the particles spinning in electric and magnetic fields can be successfully accelerated by the machine.

The assembly of the cyclotron model is even simpler than Lego.

By the way, speaking of Lego, this toy manufacturer from Sweden’s neighboring country, Denmark, has not yet appeared. It will have to wait until 1932, five years later.

This building block manufacturer that relies on the building blocks that children play with will become popular all over the world in the future, and it is also a money-making tool.

Chen Muwu felt that it was necessary to talk to Marcus about his plan to enter the children's market. Anyway, although Denmark and Sweden are neighboring countries, they have had constant conflicts in history.

The Swedish city of Malmö, across the sea from Copenhagen, the Danish capital, was originally Danish territory, but was later defeated in the war and ceded to Sweden.

Now that Sweden was asked to grab another Danish national brand, Chen Muwu felt no psychological burden.

If this children's toy factory is built, it will be able to produce Rubik's cubes and other children's toys in the future, thereby tapping into the vast blue ocean of the children's market. Even the marketing strategy, Chen Muwu has already thought of it for little Marcus.

Just copy Volvo and say that these toys are educational toys used by the Swedish royal family to enlighten the princes and princesses when they were young.

The worst case scenario is to ask Princess Ingrid, the daughter of the Crown Prince of Sweden and known as the most beautiful princess in the European royal family, to come forward to endorse this toy manufacturer.

Chen Muwu didn't believe that those Americans who had a lot of money but little background wouldn't go crazy about it.

They will definitely wave a lot of money in their hands and snap up the new children's toys that have just been launched on the counters of department stores, so that their children can also experience what the Swedish royal education work is.

Chen Muwu feels that he is a conscientious businessman. The only safety hazard of Lego toys may be that children can easily swallow the finger-sized building blocks, causing suffocation.

But compared to those crazy American toy manufacturers who put Geiger counters and radioactive elements into toy gift bags to make children interested in physics since childhood, Chen Muwu felt that he was simply a living bodhisattva.

The more Chen Muwu thought about it, the more he felt that his idea was reliable. He decided to find another time to draw the design of the Lego bricks, and then tell little Marcus about his new idea.

As long as the toy factory can be successfully completed and put into production and start to make profits in Sweden, continental Europe and the United States, then Prince's College will have another source of funds. In the future, Prince's College may surpass American universities and become the richest school in the world. .

While the matter of the toy factory was still unsolved, Chen Muwu had already started building blocks in the physics laboratory of Prince's College.

The first step is to install a mechanical switch for the radioactive particle source borrowed from Uppsala University so that the release of particles can be controlled.

Then adjust the position, place the particle source in the center of the D-type box, add alternating electric fields to the parallel ends of the two D-type boxes, and install and fix permanent magnets above and below the instrument, treating them as constant The source of the magnetic field.

All that remains is to connect the cloud chamber that Professor Wilson brought over from England to the predetermined exit position of the particles.

So far, the entire cyclotron model has basically been assembled.

The last step is to use the newly delivered glass cover customized in the Swedish factory to cover all the components on it.

Apply a generous amount of Vaseline to all crevices to prevent any leaks.

Then connect a vacuum pump to the preset hole position on the glass cover, so that the cyclotron model is in a vacuum environment.

At this point, the entire cyclotron model has been completely assembled.

The next thing to do is to turn on the power, start the machine, and verify whether this model can accelerate the particles in the particle source, thereby verifying whether the theoretical model of the cyclotron proposed by Chen Muwu is feasible.

Of course Chen Muwu knew that his theory was correct, but he still had to do it in order to successfully convince others.

Curie and his wife have stayed in the physics laboratory of Prince's College for so many days. Chen Muwu only went out for a day on the way to attend the Nobel Prize award banquet.

By now, Zhao Zhongyao and Cockcroft have ended all their publicity, speeches and interviews in Stockholm and returned to the laboratory.

Five people gathered around a cyclotron with a radius of fifteen centimeters. Even if a glass cover was added, there was still not one square meter of cyclotron. They expected that the first experiment would go smoothly and be successful.

Chen Muwu first turned on the power supply to generate an alternating electric field between the two D-type boxes to accelerate the particles.

Then turn on the mechanical switch, allowing the alpha particles to emit from the radioactive source, accelerate through the alternating electric field again and again, and then make circular motion in the D-shaped box again and again, and the speed of the alpha ions also changes with the It's getting faster and faster.

The radius of the circular motion of the alpha particles became larger and larger, and finally, they were emitted from the edge of the D-shaped box and entered the cloud chamber that had been prepared long ago, where photos of the trajectory were taken for calculation. How much energy do alpha particles ultimately carry after being accelerated by a cyclotron?

Because various possibilities had been foreseen in advance, the experiment to test the cyclotron model went very smoothly without any unexpected errors.

The camera also successfully captured a film of the trajectory of the emitted alpha particles. Chen Muwu turned off the radioactive source and stopped the power supply to the cyclotron. The first phase of their experiment came to an end.

After some simple calculations, using this cyclotron model with a radius of fifteen centimeters, the energy of alpha particles can be accelerated to hundreds of thousands of electron volts.

Although this value is not even comparable to the electrostatic particle accelerator in the Cavendish Laboratory, the acceleration energy difference between the two is an order of magnitude.

But you need to know that the radius of the cyclotron model built in Stockholm is only fifteen centimeters.

If the radius is expanded to fifty centimeters in the future, to one meter, five meters or even larger numbers, then to what extent the particles can be accelerated? That value is so beautiful that it is almost impossible to imagine.

Even if the particle is accelerated to the end, because the particle speed is too fast, relativistic effects will occur, but the energy to which the particle is accelerated will definitely be much greater than that of an electrostatic particle accelerator.

Moreover, Dr. Chen has long proposed his proposed improvement methods for the relativistic effects of accelerators.

He proposed to synchronize the frequency of the alternating electric field with the speed of the circular motion of the particles. Although this is difficult to achieve in actual operation, it is a good way to solve the relativistic effect.

However, the synchrocyclotron is still too far away for the current situation.

Now we only need to increase the radius of the cyclotron from fifteen centimeters to fifty centimeters, so that the energy of the emitted particles can reach the order of millions of electron volts, thus exceeding the ones that have appeared in universities all over the world this year. The kind of electrostatic particle accelerator found in physics laboratories.

Among the five people present, four were very excited, leaving only Chen Muwu, who had a calm look on his face.

Through this model, it was successfully proved that the theory of the cyclotron was accurate. The mission of several of them to Stockholm was basically completed by the end of 1927.

All that remains is to wait until next year to build a cyclotron that can actually be put into use at Prince's College as a gift project to celebrate the commissioning of Prince's College.

The Nobel Prize is awarded on December 12, the anniversary of Nobel's death.

By the time Zhao Zhongyao and Cockcroft finished their work in Stockholm, it was already mid-to-late December.

The Curies and Cockcroft are both Europeans. For them, Christmas is the most important event of the year.

So after the cyclotron model was verified, the three people said goodbye and left Sweden respectively to return to the UK and France for Christmas.

At this moment, the only two people left in Stockholm are Chen Muwu, who is waiting to receive the Royal North Star Medal next New Year, and Zhao Zhongyao, who is not very interested in Christmas, the Western winter solstice.
