Chen Muwu, who has been spending time in the David Faraday Laboratory in London, is not very clear about the news from the Cavendish Laboratory.
During this period, although Oppenheimer came to London from Cambridge University.
But since Chen Muwu left at the beginning of the year, he has been following Old Thomson. He doesn't know or want to know about Rutherford's situation. Of course, he doesn't know about Chadwick, the deputy Rutherford relies on most. To get married.
Chen Muwu was only thinking about making money and prizes, and didn't have much time to maintain relationships.
If it hadn't been for the discovery of heavy hydrogen this time, maybe he wouldn't have written to Rutherford.
After all, although plexiglass is profitable, it is not an important experimental result.
If you write a letter to the teacher to tell the good news, you might even get scolded by Rutherford.
Because in the eyes of a pure experimental physicist like him, engaging in theory is a heretical thing, and engaging in inventions, and moreover chemical inventions, is completely unprofessional.
Even for the matter of heavy hydrogen, Chen Muwu did not expect that his teacher would have such a big reaction at first. Not only did he come from Cambridge in person, but he also called Chadwick from Liverpool to London, who was getting married.
Chadwick, who was born in 1891, can be regarded as a model of late marriage and late childbearing.
He is already thirty-four years old this year, but he remained single until Chen Muwu left Cambridge University at the beginning of the year.
It's not that Chadwick didn't want to get married early, it was just that when he was young, he encountered a huge unlucky thing.
Ten years ago, he was Chen Muwu's age.
Chadwick, who had just received a Master of Science degree from the University of Victoria, received an 1851 Research Scholarship, which allowed him to temporarily leave Rutherford in Manchester and study in Germany.
In the second year after arriving in Germany, World War I broke out.
Chadwick, who was still in Berlin, was directly taken as a prisoner by the Germans and imprisoned in a prisoner of war camp.
In the past few years when Chen Muwu achieved results, Chadwick could only count the stars in the prisoner of war camp.
After the war ended, he returned to England as a twenty-seven-year-old young man who had not yet obtained a doctorate.
Thinking of getting married first and then starting a career, he followed Rutherford from Manchester to Cambridge and earned a doctorate in philosophy from Gonville and Caius College, Cambridge University, through his own efforts.
Because of Rutherford's appreciation, he was appointed deputy of the Cavendish Laboratory.
Now that Chadwick is finally successful in his career, he has begun to think about starting a family.
At the beginning of the year, while at home in Manchester, he made a chance trip to Liverpool, where he met the daughter of a Liverpool Stock Exchange broker.
The relationship between the two heated up rapidly, and by summer, they were already considering getting married.
At the critical moment of preparing for the wedding, Rutherford called him over with a telegram.
"Mr. Chadwick, congratulations! If you hadn't come to London this time, I wouldn't have known that you were getting married. I'm really sorry that I asked you to come all the way here when I was busy preparing for the wedding. .”
Although Chen Muwu was embarrassed, he always wanted to say polite words.
"Business matters are more important. It won't matter if I get married two days earlier and two days later. Sir Rutherford said that your discovery is great. It's hard to find evidence of the existence of electrically neutral particles in atomic nuclei. "
"The teacher has told me his idea this morning. He wants to use hydrogen nuclei to bombard heavy hydrogen nuclei. If something other than protons can be found in the nuclear reaction products, maybe the newly generated product will be electrons. sexual particles.
"There is currently no better way to accelerate protons. I suggested to the teacher that we build an accelerator in the Cavendish Laboratory."
Chen Muwu began to lie about building an accelerator again, although he discovered that neutrons did not need an accelerator to accelerate alpha particles.
But the method of bombarding deuterons with hydrogen nuclei was proposed by Rutherford, who could just pull the flag and take advantage of the tiger's skin.
While Chen Muwu and Chadwick were talking about accelerators, Kapitsa stared at the spectrum on the glass plate, thoughtfully.
"Chen, have you had any experience of failure since you arrived in the UK? Why do I feel that no matter what you do, you are very successful? And these successes seem to come very easily and without any effort."
Chen Muwu felt that Kapitsa was going to make a cliché again in the next sentence, asking him why he was so successful.
But he still underestimated the Russian brain circuit, and could not imagine what Kapitsa said next: "Although you are the best student of Old Crocodile, you are not James' best person."
James is Chadwick's first name. Kapitsa, who is three years younger than him, has no problem calling him by his first name. However, Chen Muwu, who is nearly one year younger than him, always calls him by his last name.
Best student is the best student, but best man is not the best person, but the best man at a special wedding.
Kapitsa made a pun, as if he was showing off his status as the best man.
"Peter, you're right. I really can't compare with you on this point, because in my impression, it seems that the best man has to choose the ugliest one among his friends, in order to bring out the tallness and handsomeness of the groom. .”
Chen Muwu made a joke with his good friends, but he was thinking about something else.
Kapitsa is already married, how can he still be someone else's best man?
But he couldn't ask directly because Kapitsa's first wife died a few years ago after contracting the Spanish flu.
Chen Muwu could only guess in his heart that maybe because of different customs, the British might not be taboo about this matter.
On the next day, Aston, who had lent Chen Muwu a vacuum pump and was reciprocated by Xiao Chen by sending him a more precise vacuum pump, also came to London from Cambridge.
As an expert in the study of isotopes, Rutherford invited him to the David Faraday Laboratory just to have this authority confirm that Chen Muwu had indeed discovered the isotope of hydrogen.
In fact, the line on the spectrum is very clear, and there is no need for Aston to confirm anything.
It was more like he was invited by Rutherford to endorse his students.
Everyone in the Cavendish Laboratory went to the Royal Institute for team building. As the director, Old Bragg was helpless.
In terms of seniority, he can be regarded as Rutherford's teacher.
While Rutherford was still growing potatoes in New Zealand, Bragg was already a professor of mathematical physics at the University of Adelaide in Australia.
On his way to study in the UK after leaving New Zealand, Rutherford also visited the ship when it docked in Adelaide and asked old Prague some questions about life in the UK.
But in terms of status, Old Prague is now inferior to Rutherford.
Although everyone is a fellow of the Royal Society and they all run a laboratory, Rutherford is about to take over as the president of the Royal Society, and his Cavendish Laboratory, whether in terms of funding, talent or The research results are much better than those of the Royal Research Institute.
The only thing that old Bragg can beat Rutherford is that he won the Nobel Prize in Physics.
But there was nothing he could say. Once he said it, he was afraid that his old arms and legs would not be able to withstand the fists of the strong New Zealand man.
Both Rutherford and Aston named themselves to bring more deuterium back to the Cavendish Laboratory for research.
The former is still thinking about his bombardment experiment, while the latter wants to put heavy hydrogen nuclei into a mass spectrometer and try to measure some physical and chemical properties of heavy hydrogen.
Opening their mouths at the top but breaking their legs at the bottom, Chadwick and Kapitsa hurriedly took up their posts in this laboratory after receiving simple training from Chen Muwu.
They must use these few days to produce the heavy hydrogen they want.
And why didn't Chen Muwu do it himself?
Because unlike Chadwick and Kapitsa, he is a distinguished fellow of the Royal Society. Together with Rutherford, Old Bragg and Aston, he will go to the Royal Society to participate in the report on the discovery of heavy hydrogen nuclei. .
Chen Muwu is naturally the keynote speaker of this report meeting.
Rutherford, who presided over the meeting, proudly announced to the audience that this was the first time the discovery of heavy hydrogen nuclei was announced to the world.
But in fact, on the first day he arrived in London, he asked Chen Muwu to send the news and photos of the discovery of deuterium to the editorial department of Nature.
Compared to Rutherford's first reaction, which was whether the electrically neutral particles in the atomic nucleus could be discovered from the deuterium nucleus, the monks present breathed a sigh of relief when they heard that the deuterium nucleus had been discovered.
The discovery of heavy hydrogen nuclei finally made it possible for everyone to explain why the same very pure pure water has different densities measured in different places around the world.
Some people also draw inferences. Since there are heavy hydrogen nuclei with a relative atomic mass of 2, are there heavier hydrogen nuclei with a mass of 3?
What is the maximum relative atomic mass of an isotope of hydrogen?
Chen Muwu's clumsy method of finding deuterium by evaporating liquid hydrogen at low temperatures may not be suitable for tritium.
Because the amount of tritium in hydrogen is very small, 0.016% of the hydrogen atoms on the earth are deuterium, but only 10 to the 18th power, that is, one billionth of a billion is tritium.
If you want to find tritium, you still need to work hard to achieve a miracle, although in Rutherford's idea, bombarding a deuterium target with hydrogen nuclei cannot obtain neutrons.
But he then used deuterons to bombard deuterium targets, and finally discovered the existence of "superheavy hydrogen" tritium with a relative atomic mass of 3 for the first time.
But the prerequisite for discovering tritium is to build an accelerator first.
After introducing the discovery process of heavy hydrogen, Rutherford led everyone to discuss what name should be given to this heavy hydrogen.
As the discoverer of heavy hydrogen, Chen Muwu was the first to express that he had no interest in naming this isotope.
He sat in his seat and watched the discussion of the Royal Society fellows with great boredom. They spoke Greek freely and quoted scriptures frequently.
Chen Muwu has always found one thing very mysterious, and that is why different isotopes of hydrogen have different names and symbols, but isotopes of other elements do not have this treatment?
The next day, the science page of The Times reported on yesterday's meeting of the Royal Society with the headline "The Last Man Who Knows Everything".
And the person described in this title is of course Chen Muwu.
Chen Muwu was reading the day's newspapers in David Faraday's laboratory when a new guest came to visit.
This person can be regarded as coming from afar, and is a little closer than Chen Muwu who came to England from China.
The Indian with a turban on his head introduced himself in English with a South Asian accent: "Hello, Dr. Chen, I am Chandrasekara Raman, from the University of Calcutta, India.
"I listened to your report at the Royal Institution yesterday and learned that you are currently conducting research at the Royal Institution, so I came here to visit you."
Raman became a fellow of the Royal Society as early as 1924, and Bragg Sr. was also elected while teaching at the University of Adelaide.
Neither of these two people had achieved any impressive academic results at the time, but it seemed that the Royal Society was particularly tolerant of them who taught in several major colonies and promoted kingship, and the threshold for membership was very low.
In contrast, if you stay in the UK to engage in research, it will be very difficult to enter the Royal Society.
Chadwick had to wait until 1927 to become a fellow, and Kapitsa two years later.
After de Broglie, Chen Muwu was once again approached by the real owner.
Raman had been studying the magical phenomenon of visible light scattering for a long time, and then he was stopped by Chen Muwu.
He would never have imagined that it was Chen Muwu who published his research results in advance and expressed his gratitude to Dr. Chen for solving the problem that had been bothering him.
Of course, Raman’s visit this time was not just to say thank you. As a pioneer in physics education in India, he also wanted to discuss with Chen Muwu the future direction of physics.
Hearing this topic, Xiao Chen suddenly became interested. He took Raman to the laboratory where he discovered heavy hydrogen, pointed to the machine surrounded by Chadwick and Kapitsa and introduced: "Professor Raman, please see, it was on this machine that I discovered the first isotope of hydrogen.
"It's just an accidental discovery. My original intention to buy this machine was to study superconductivity issues in low-temperature physics.
“I think superconductivity is like a mountain of treasures that is so understudied and under-understood.
"We can now achieve superconductivity at a temperature of 7 Kelvin, so can we find superconducting materials at 10 Kelvin? With the deepening of research, will the critical temperature of superconductivity be higher in the future? One hundred Kelvin? Two hundred Kelvin? Even three hundred Kelvin room temperature superconductivity?”
Since you Indians can fool the whole world that you have found room temperature superconducting materials, of course I, Chen Muwu, can also fool you Indians in advance!
Have you eaten the room-temperature superconducting melon that Third Brother recently created? I feel more like a scammer, and it’s the third brother’s fault.
