The secretary of the Institute of Theoretical Physics soon brought Professor Biermann to Bohr's office.

Although as professors at the University of Copenhagen, the two of them have met many times at various meetings and events at the school, and they can barely be regarded as the kind that looks down and does not look up.

But it's the first time I've met one-on-one alone.

Bohr wondered why Bierman, a chemist, said that he came to him because of Chen Muwu's affairs.

That Chen Muwu, who is not doing his job, is just a matter of not studying theoretical physics, could it be said that he didn't even do physics experiments this time, and switched to studying chemistry?

If this is the case, then Bohr is more or less saddened by this matter.

is obviously such a good seedling, why did he go astray?

After the meeting, Bierman was the first to explain his intentions.

"Good morning, Professor Bohr. Yes, I am the President of the International Union of Pure and Applied Chemistry, and I have received today a telegram from the Federation from Stelmo, Sweden, to the headquarters office of the Federation in Zurich, Switzerland.

"The telegram was signed by the Prince College in Stockholm, and the content of the telegram said that the laboratory staff of the new Prince College suspected that element 85 had been discovered, and asked our federation to send someone to Sweden to verify whether their discovery was correct or wrong.

"Some time ago, the newspapers in Sweden reported that under the command of the Swedish crown prince, they built this new school, the Prince College, and hired Chen Muwu to teach at the school.

"This has also been reported in the local Danish newspapers, and I think you have heard of it.

"I'm wondering now if this telegram was sent by Chen Muwu from Stockholm to our federation?

"Professor Bohr, how credible do you think this is?

"Also, do you think it is possible for Chen Muwu to discover a new element?"

Bohr, of course, had read the news they had reprinted from Swedish newspapers in local Danish newspapers, and even if the newspapers didn't report it, Bohr would have known that Chen Muwu was going to Denmark's neighboring country Sweden to run a school.

At first, when he first learned of this news, Bohr was very sullen.

He felt that it was difficult not to be competitors between Copenhagen and Chen Muwu in Stockholm, two countries separated by only a short strait, and both based on the study of physics.

At that time, Bohr had raised his concerns to Chen Muwu, and he advised Chen Muwu that there was no need to spend a lot of money to build another school, and that Sweden and Denmark were in the same Nordic Europe, and the two of them could become one and do something in physics education vigorously.

Chen Muwu said a lot of high-sounding things in his response at the time, such as that his school in Stockholm was to cultivate basic talents for his country, which did not conflict with Bohr's cultivation of high-end physics talents in Copenhagen.

But only he knows the actual situation of why Chen Muwu was in Sweden and did not go to Denmark.

As a neighbor of Germany, Denmark, like Poland and France, was invaded by this neighbor shortly after the outbreak of World War II, and eventually occupied by the whole territory.

How much does he not want to open it, so that he will spend a lot of money to build a school in the occupied area?

Bohr has always been skeptical of Chen Muwu's response, he always felt that his junior brother had great ambitions, and he was not as harmless as he seemed on the surface.

Today, I met Professor Bierman in my office and heard new information about Chen Muwu from him.

The bad news is that Chen Muwu lied to himself before, and his university in Stockholm was not purely for teaching, but because the school had not yet officially opened its classes, he suspected that he had already achieved new results in the experiment.

And the good news is that Chen Muwu's experiment this time is in chemistry, not physics.

Thinking of this, Bohr took out his pipe from the pocket of his suit, filled it with tobacco, lit it, took a deep breath, and spat out a smoke ring.

After temporarily relieving his addiction to smoking, he said to the guests in the office: "Professor Bierman, although I haven't seen the telegram you mentioned, but listening to you relay the contents of the telegram, I think the person you said about the telegram is very likely to be Dr. Chen Muwu.

"The Prince's College in Stockholm, as far as I know, has just been built, and it hasn't recruited enough teachers and students to open yet, so I think that among the limited staff of that school, it seems that only Dr. Chen Muwu can do this experiment.

"This is not the first time that Dr. Chen Muwu has been involved in the field of new element discovery, I don't know if you remember that a few years ago, he had already found the first isotope of hydrogen in the United Kingdom through the study of low-temperature physics.

And just last fall, he used his own particle accelerator to find a second isotope of hydrogen.

"If I had to predict, I think it's very likely that Dr. Chen Muwu has really found the new element you mentioned.

Moreover, it is very likely that his discovery of this new element is not a new substance separated from seawater or ore as previous chemists have discovered new elements; It is quite possible that he has taken a new path. ”

Bohr is worthy of being the person who knows Chen Muwu the most in the entire University of Copenhagen, and his prediction cannot be said to be crooked, but can only be said to be exactly right.

On this trip, Bierman came to Bohr to ask for specific advice.

Hearing the other party's answer, Bierman basically confirmed in his heart that it should be Chen Muwu who sent this telegram.

But he still had a question to ask: "Professor Bohr, do you think I should accept the invitation on the telegram and go to Stockholm in person?" ”

The International Union of Pure and Applied Chemistry forwarded this telegram from the Prince's College to Professor Bierman, the president of the Federation, in order to ask him his opinion, whether the Federation should send people or not? If so, who will be sent?

Bierman felt that Denmark and Sweden were neighbors, and that the distance from Copenhagen to Stockholm was not too far, and that it was only necessary to cross the channel by boat, then take an overnight train and wake up the next day.

If Chen Muwu really made a new discovery in chemical elements, then it is not impossible to go to the mountains in person.

Bohr took another deep puff of his cigarette: "Professor Bierman, I think it's best to go once."

"After all, Dr. Chen Muwu is still a scientist whose main business is physics, even if he crosses over to chemical research, but he has a 'specialization', I think his knowledge of chemistry is still not enough after all.

"According to his character, if he had been stable from the beginning, I think he would have written a paper and published it long ago.

"But now there is only a telegram, no papers, as you said just now, that he wants your federation to send a chemist to test his newly discovered substance.

This sentence revealed that he actually had little confidence in this experimental product.

"In that case, I thought you might as well go to Stockholm and help Dr. Chen Muwu complete the last step of his experiment.

"If Dr. Chen Muwu does discover a new element, then your name must be on the credit book.

"And if the new element he discovers is just a fake message, it won't delay you for too long."

Bohr deliberately used the reason for discovering new elements to tempt Bierman, although some of the things he did as a junior brother before were not very kind, but this time he still helped Chen Muwu.

"Professor Bohr, since you say so, I will send a telegram back to the Prince's College in Stockholm when I return, informing them that I will leave for Sweden on the same day.

"Thank you for your advice, Professor Bohr, and I'll take my leave."

Receiving a positive response from Bohr, Biermann planned to go back and send a telegram, and then began to prepare his luggage.

But Bohr stopped him again: "Professor Bierman, don't worry, we have a telegraph in the Institute of Theoretical Physics that can send telegrams." ”

Bohr proposed his telegraph system to Chen Muwu early on, and also installed a telegraph.

However, Chen Muwu, who designed a set of common character codes for papers, has never implemented the telegram, and no one has been installed in the Cavendish laboratory.

Accepting Bohr's invitation, Biermann and the two of them who stayed behind quickly prepared this return call to Sweden.

Instead of waiting for the next telegram to come back from Stockholm, Bierman left the Institute of Theoretical Physics and returned home to pack his belongings.

Chen Muwu didn't expect that only a day after his telegram, the International Union of Pure and Applied Chemistry sent him a reply.

What he didn't expect was that the address of the return call was not Zurich, Switzerland, but to Copenhagen, Denmark.

Chen Muwu didn't have time to care why the telegram was sent from Copenhagen, he only cared about what the telegram was about.

Dr. Chan:

"I will go to Stockholm, Sweden on a certain day, please inform the specific address of the Prince's College, and prepare experimental equipment and medicines such as so-and-so, so-and-so, and so-and-so.

President of the International Union of Pure and Applied Chemistry, Bierman

"Year, Month and Day"

At first, Chen Muwu just thought very simply, let the Chemical Federation send a chemist with rich experience, you like this element is indeed the No. 85 new element of iodine, and then issue a report.

He didn't expect the president of the federation to send a telegram back to him, saying that he was coming to Stockholm in person.

And it was clear that he was in the outgoing call, and what was marked at the end of the payment was not my name, but Prince of Stockholm College.

So how did this chairman Bierman learn his real name?

Chen Muwu hurriedly drafted a reply letter in accordance with the request on the telegram, indicating the specific address of the Prince's College in Stockholm.

He took the written telegram to the telegraph office, and when he filled in the shipping address on the telegram, Chen Muwu noticed another interesting thing.

The telegraph, a communication tool, has been charged according to the number of words since it was put into commercial use.

In the early days when telegraphs were expensive, people were trying to compress the number of words as much as possible in an attempt to deliver more news for less.

However, the address is also counted in the word count, and if a cross-border telegram is written, the address alone must indicate the country, province, state, city, or township to which the telegram is to be sent, and then the specific address.

This will likely result in an address with more words than the content of the telegram and will cost more.

So in order to be able to reduce the price of telegrams, telegraph offices around the world have introduced something called telegram registration.

Registered telegram is generally made up of a few digits, which is equivalent to a telephone number in the future telephone era.

Moreover, there is a special telegram registered address book in the telegraph office, which can easily query the address of the recipient corresponding to the telegram registration, and can also reverse the telegram registration from the address, so as to save their telegram consumption when sending telegrams.

When Chen Muwu filled in the telegram address at the telegraph office on the outskirts of Stockholm, he asked the staff at the counter very curiously, and the telegram bracket numbers on the address corresponded to where in Copenhagen they were.

The counter staff flipped through the address book, and then told Chen Muwu a specific address-

Institute of Theoretical Physics, University of Copenhagen.

Strange, strange, why did Bierman's reply come from Bohr's Institute for Theoretical Physics?

Although Chen Muwu was curious, he did not send another telegram to Bohr, asking how things had developed like this.

He still had something to do, and that was to prepare the equipment and medicines that the other party might need to use for the experiment, according to the telegram Bierman had sent him earlier.

Bierman felt that since Chen Muwu said that he had discovered element 85, then it was the halogen element of group VII.A.

Since it is a halogen, and the name is also iodine-like, the chemical properties of this element 85 should be similar to the chemical properties of iodine.

Therefore, the chemicals and instruments that Bierman asked for in the telegram were basically related to the test of iodine.

- However, there is no aqueous starch solution in it, and it is true that iodine turns blue when it meets starch, but whether iodine-like and starch will react, and which color of the reaction is, no one can tell.

This time it was a very common chemical instrument and medicine, and Chen Muwu would not send Frederick to Uppsala in the northwest of Stockholm to borrow something from Uppsala University.

Of course, it was not easy for him to buy in the market temporarily, so after sending the telegram, Chen Muwu drove the Volvo to the Royal Institute of Technology in Stockholm.
