Reborn and become a Great Scientist

221 Chapter 169

The recipient of this telegram from Copenhagen was not Chen Muwu, but Rutherford.

Naturally, Bohr, the director of the Institute of Theoretical Physics, said in the telegram that he would set off in the near future, take a ship from Copenhagen to Norwich Harbor in England, and then take a train to attend the meeting of the Royal Society in London.

He asked his teacher Rutherford to go to London to meet him, and he also specifically mentioned in the telegram that his smartest junior, Chen Muwu, must also come with the teacher.

So as soon as Chen Muwu returned to Cambridge University from Paris and returned to the Cavendish Laboratory, Rutherford asked Chadwick to call him to his office and showed him the telegram.

It was neither unexpected nor unexpected that Bohr went to the Royal Academy for a meeting.

Not surprisingly, the Royal Academy announced last year the list of newly admitted members in early 1926.

Both Bohr and Planck were on the list, and they would become foreign fellows of the Royal Academy.

It may seem strange that Bohr and Planck achieved fame in physics much earlier than Chen Muwu.

But why did they not become Fellows of the Royal Society until 1926?
This is one year later than Chen Muwu who became a member last year!
The composition of the Fellowship of the Royal Society is divided into three situations.

One is a full member, commonly known as FRS, Fellowship of the Royal Society.

The other is foreign members like Bohr, ForMemRS, Foreign member of Royal Society.

The last one is HonFRS, Honorary Fellowship of Royal Society.

These three titles are awarded to different groups of people.

Honorary Fellowship is exactly like the word in the name, purely an honorary title.

The winners can also be considered to have made certain contributions to scientific research, but the achievements are not enough to be awarded fellows or foreign fellows.

As for the members and foreign members, they are all people who have made sufficient achievements in scientific research.

The difference between the two is that the nationality of the foreign members and the location of the major achievements are not within the United Kingdom and its overseas colonies.

Although Chen Muwu is Chinese, his research results in physics and astronomy were all carried out in the UK, so he was awarded the title of fellow, not a foreign fellow.

This can also be regarded as a kind of recognition of him by the British academic circle, which means that you are one of us.

In the future, the same will be true for Kapitsa, even though he is a Sulian.

In fact, the foreign fellowship of the Royal Society is more like an honorary title. Scholars who have won this title do not need to go to London to attend the initiation ceremony in person.

Although Planck is two years younger than Old Thomson, he is already 68 years old this year.

At his age, he would definitely not take the train from Berlin to Calais, France, and then transfer to England by ship.

Chen Muwu originally thought that Bohr, like Planck, would not attend the initiation ceremony in London.

But I didn't expect that the telegram said that he would come in person, which was surprising.

The last time Bohr visited England was in 1923.

At that time, he had a great reputation. The building of the Institute of Theoretical Physics had just been completed. At the end of the previous year, he won the 1922 Nobel Prize in Physics.

During that visit to the UK, Bohr met his teachers, classmates and colleagues in the UK, and received two honorary doctorates from Manchester Victoria University and Cambridge University by the way.

After that, Bohr has been busy with various things of his Institute of Theoretical Physics: buying land, expanding, staring at the construction of the new building and so on.

Basically, he has not left Denmark in the past few years, and only visited Stockholm, the capital of neighboring Sweden, once.

This was in order to try everything possible to persuade Chen Muwu to stay in Copenhagen, and to accompany him to receive a Nobel Prize.

Bohr also did not attend the Solvay Conference in 1924, so he has not met his teacher Rutherford for almost three years.

So Bohr chose to participate in the initiation ceremony of the foreign member of the Royal Society held in London, and also thought of going to England to meet his teachers and classmates.

Of course, he had to swing the hoe a few more times to see if he could dig up his junior brother Chen Muwu to Copenhagen.

This young man is a little bit dishonest. He obviously asked him before, if he thinks that physics will make progress in superconductivity at low temperature in the future, otherwise why would he send that foreign student to Leiden University in the Netherlands?
Chen Muwu vowed at the time that there might be some progress in low-temperature physics, but the mainstream is definitely still in the quantum field.

As a result, after he returned to the UK, he published three papers in a row, all of which were the results of low-temperature physics experiments.

Bohr didn't understand why Chen Muwu would lie to himself, a loyal elder.

From the time when Manchester followed Rutherford, he did not do many experiments by himself, but acted as Rutherford's theoretical consultant.

Bohr has not done experiments for more than ten years. Could it be that Chen Muwu was afraid that he would steal his results, so he lied on purpose?

If this is the case, there is another point that does not make sense.

Since it was a lie that Chen Muwu told himself that low-temperature physics had no future, what he told Yoshio Nishina should be the truth.

Because after listening to what he said, Yoshio Nishina transferred from Denmark to the Netherlands and devoted himself to the research of low temperature physics.

But didn't Chen Muwu say that he hated himself?
Is this sentence also a lie to lie to myself?

Bohr thought in his heart that during this meeting, in addition to continuing to poach Chen Muwu, he also had to ask him why he lied to him.

Bohr asked to go by himself, but Chen Muwu had to go.

He also had no way to complain that Bohr was unreasonable. A telegram sent Rutherford, who was already so old, to London.

Because Rutherford was originally the president of the Royal Society, no one could participate in the plenary meeting convened by the Royal Society, but he was the only one who could not.

So Chen Muwu, who had just returned to the Cavendish Laboratory, rested at Cambridge University for a few days, and then followed Rutherford and other missionaries to London by train.

The Cambridgeshire-to-London line, though merely a link off the main British rail line, has often had moments of being the most intelligent in the world.

Just sitting with these professors and teachers whose average age is more than twice his own, Chen Muwu really couldn't find a common topic with them.

He even began to miss the days when he and Kapitsa took the train together a few days ago.

Hearing him babble about his love story with Anna was better than enjoying a tobacco-smelling barbecue in a first-class compartment.

Occasionally, his teacher pointed the "spearhead" at him and made some jokes.

Rutherford also knew that Chen Muwu had gone to Paris, France during the vacation, and it was self-evident who he was looking for there.

He still remembers what he told Chen Muwu as a wedding witness on the train from Liverpool back to Cambridge last year.

Now they are also taking the train, so Rutherford took this matter out and made fun of it again.

After several hours of torment, I finally arrived in London.

Chen Muwu declined the invitation to stay at the place prepared by the society with others, but ran to the British Legation as usual.

Iron legation, iron Zhu Zhaoxin.

Zhu Zhaoxin has been preparing for his post since he was promoted to the post of Minister to Italy last year.

From then on, every time the two met, they would make each other think that it was the last time they saw each other in England.

As a result, during this year, I met at least three times for the last time.

Without any accident, Zhu Zhaoxin is still staying in London.

Also without any surprises, this time is indeed the last time in the UK.

The news finally came from China that the new envoy to the UK has been confirmed, and he will start from China and come to the UK to take up his post after the Spring Festival.

Although on the list given by the Ministry of Foreign Affairs, the new envoy is Yan Huiqing who once served as prime minister.

But Zhu Zhaoxin told Chen Muwu not to have too much hope.

He had been Chargé d'Affaires in the UK for five or six years, and the nominal envoy to the UK was always Gu Weijun, but the time that this envoy Gu had been performing duties in the UK was less than a few months from the beginning to the end.

According to Zhu Zhaoxin's estimate, the former Prime Minister Yan will also not stay in the UK for long.

Maybe he didn't come at all, and would just send another counselor or first secretary to continue acting as chargé d'affaires.

This is actually good news for Chen Muwu. The lower the status of the "hunter on behalf of the sky" in the UK, the better he can act cheaply.

……

Welcomes new Fellows to the Society and presents some of the various Medals and Medals affiliated with the Royal Society for their achievements in the past year.

Chen Muwu had long foreseen the boredom of this meeting. Although Bohr appeared in the meeting place on the last day, the two of them just exchanged a simple greeting.

"Professor Bohr, congratulations on becoming a foreign member of the Royal Society!"

"Oh, Dr. Chen, long time no see. You have achieved so many achievements in the past year, which is really enviable."

After exchanging pleasantries, Bohr did not continue to talk with Chen Muwu, and he was not in a hurry to start wielding a small hoe at this moment.

After attending the ceremony of the Royal Society in London, Bohr will live in Cambridge University for a few days, give a report, visit the laboratory, and exchange experience with his physics colleagues.

At that time, there will be plenty of time between the two of them.

But for Chen Muwu, this trip to London was not a waste of time.

On the second day after the meeting, on January 1, Rutherford invited several fellows of the Royal Society, including his two good students, Chen Muwu and Bohr who came from afar, to London Soho ( Visited a laboratory at 26 Frith Street, Soho.

At first he heard that it was a laboratory, or a laboratory built in a rich area. Chen Muwu thought that it was probably because the rich man in London was bored and wanted to study science on a whim.

He was able to make this speculation not entirely out of hatred for the rich, but because he was visiting fellows of the Royal Society, along with reporters and photographers from The Times.

Only boring rich people like to make such a big battle.

But after waiting, he realized that his previous guess was completely wrong. There are really new things in this laboratory.

John Baird, a Scotsman, was the owner of the laboratory and the first person in the world to invent television.

As early as March 3 last year, he had already conducted a three-week public demonstration at Selfridges department store, using the television system he invented to show people moving silhouettes.

This time, through The Times, he invited members of the Royal Society to visit the laboratory to testify that he had indeed invented a new gadget that could transmit moving images in real time.

When the power switch was turned on, a disc with many holes began to rotate, and the light bulbs behind the disc were continuously blocked and released. The light passing through the holes flickered on and off, shining on Baird's assistant, Oliver Harley. Chinson's face, the reflected light is then captured by a device and converted into an electrical signal.

After these electrical signals were transmitted, and a series of reverse operations, Mr. Hutchinson's face was finally displayed on Baird's TV.

The photographer of "The Times" pressed the shutter of the camera, and the world's first televised photo was recorded in the photographic film.

Chen Muwu was not very interested in the television invented by Baird.

Because a mechanical scanning TV like this will be eliminated in a few years.

TVs that use electronic scanning will be the mainstream of future TV development, and it is precisely this kind that will eliminate mechanical ones.

However, Chen Muwu's trip was worthwhile. He got two inspirations from this visit to the laboratory.

The first point concerns the electron microscopy project that has been put on hold by Cavendish Laboratory.

What Chen Muwu hadn't figured out before was how to present the results of the electron microscope observations in concrete terms.

The solution he thought of at the time was to put a imaging negative in it every time a sample observation was made, and record the final result of the observation by taking a photo.

But now that there is a TV, it is also possible to directly transfer the observation results of the electron microscope into electrical signals, and then install an additional fluorescent display screen, so that the microscopic results can be observed without frequently changing the negatives.

In the 20s, it was undoubtedly advanced to be able to use this technique on an electron microscope.

As for the second point of inspiration, it was overheard by Chen Muwu when Baird was interviewed by The Times after the demonstration.

He told reporters about the arduous process of developing the TV, saying that he was once exposed to a voltage of up to one thousand volts in an experiment.

Although no one was killed in this accident, it still deformed his hand, left him disabled, and was kicked out by the landlord.

Baird continued to reminisce over there, but Chen Muwu's thoughts had long been on high voltage electricity.

Now his group at the Cavendish Laboratory is also working on something related to high pressure.

This high pressure can not only accelerate particles and shatter atoms, but can also electrocute people.

In order to prevent this from happening, the environment around the generator must be insulated.

This is an oversight that I have never noticed before, and this oversight is still life-threatening!

Fortunately, the materials for the generator have not been fully prepared, and the formal construction has not yet begun.

The prison is not broken, and the sheep are not dead, so there is no need to mend it, as long as it is strengthened in advance.

If people were killed because of ignoring this point, that would be the real big trouble!
