“And that roommate of yours is just like a telephone pole.
"This morning, while you were still sleeping in your room and didn't get up, I went to the kitchen to make myself a cup of coffee. Seeing that the weather outside was a bit gloomy, I wanted to have a conversation with your roommate.
"I asked casually at the time, does it seem like it's going to rain outside?
"Talking about the weather has no other meaning. It's just a way to quickly stir up topics and shorten the distance between people. Guess what the British guy said back to me?"
"What?"
"He didn't reply at all, but stood up from the chair next to the table, walked to the window and looked outside for a while, then turned back and told me seriously with a straight face, it's still dark outside now. It didn’t rain.”
"Pfft! Hahahaha..."
De Broglie complained angrily to Dirac, making Chen Muwu laugh.
He had no doubt that these were all made up by De Broglie.
Because his roommate, Dirac, seemed to be someone who could do such things and say such things.
General Electric's vacuum pump worth six thousand US dollars has been transported to the Cavendish Laboratory by de Broglie's servants this morning. Now it only needs to be connected to the electron diffraction tube that Chen Muwu had prepared long ago, and then Start the vacuum pump and slowly pump out the air in the tube to reduce the degree of vacuum to the lowest level. Then you can judge from the pattern displayed on the photographic film whether the electron is a wave or not.
De Broglie, who became a monk halfway through his studies of history, was not a theoretician who was gentle in words but not in actions.
He operated radios on the Eiffel Tower for several years, and personally conducted experiments related to X-rays in his elder brother's laboratory.
So now in the electron diffraction experiment, he did not appear at a loss, but he was just a little nervous about the unknown experimental results.
But when he looked at Chen Muwu next to de Broglie, the old man was even more calm and relaxed.
He had already known the results of the experiment. As long as the vacuum was low enough, the electrons passing through the gold foil would definitely leave a diffracted concentric ring pattern on the photographic film.
The only difficulty in this experiment is that the vacuum pump can provide a high degree of vacuum, but its efficiency is somewhat low. If you want to pump the vacuum degree in the diffraction tube to seven decimal places, it will take at least four or five hours.
De Broglie stared at the equipment on the table intently, fearing that if he didn't pay attention, it would affect the final result.
Chen Muwu, however, couldn't bear his temper. He didn't want to squeeze his head with De Broglie's and stare at the pointer on the pump. He simply left the door of the laboratory and planned to go to the room where no one except him usually did much. It was quiet in the conference room where some people were going. Think about what you should write in your next paper after this experiment is completed.
As soon as he walked out of the laboratory door, Chen Muwu found Stoner from the laboratory next door, standing outside the door smoking a cigarette.
Today was the first time he saw a real person. Chen Muwu wanted to say hello and leave, but unexpectedly Stoner took his pipe out of his mouth and stopped in the middle of the road to chat with him.
"Chen, I read the paper you published last year, explaining Bohr's atomic model by treating electrons as waves.
"The experiments I'm doing now are related to the energy levels of electrons. I used X-rays to conduct experiments on several different atoms. I don't know if I have discovered a new rule.
"Your theory in this area seems to be very profound. Can you help me take a look at the experimental results?"
Well, just when I thought the electron diffraction experiment was boring, another job came to my door.
"Well, I don't have anything to do now anyway."
Chen Muwu followed Stoner and entered the door of the next door laboratory.
Stoner picked up a pile of experimental data from the table and handed it to him.
"Look, Chen, about the integer sequence discovered by Rydberg before: 2, 8, 18, 32..., and Bohr proposed in his atomic model that each integer corresponds to the maximum number of electrons that the electron layer can accommodate. Quantity. I seem to have found a solution for this sequence.
"According to my recent experimental results, I am considering dividing each electron layer into several electron sub-layers. According to different angular momentum quantum numbers L, each electron sub-layer can accommodate up to 2 (2L+1) electrons.
"But now there is another problem. I found through experiments that when the maximum number of electrons can be accommodated, there can only be (2L+1) orbits in each sub-layer. That is to say, there can only be at most (2L+1) orbits in each orbit. Two electrons are enough..."
Before Stoner finished speaking, Chen Muwu's mind was already in a mess.
Pauli Exclusion Principle? !
Of course Chen Muwu knew what Stoner was talking about, and he also knew why there could only be at most two electrons in each orbit.
Isn’t it just electron spin?
The spin of an electron can only be positive or negative, so there can only be at most two electrons in each orbit.
But he didn’t know how the Pauli Exclusion Principle was proposed, and what he didn’t even know was that the Stoner in front of him and the paper on the experiment he was doing now would be published in a journal in the future. One of Pauli's sources of inspiration.
Seeing Chen Muwu standing beside him, Stoner didn't know what was going on with this genius in the Cavendish Laboratory. Did he take the wrong medicine when he went out today?
"Chen, what's wrong with you?"
"No, it's nothing. Mr. Stoner, I think your experiment is very good. You can go a step further and try a few more atoms. See if this rule only exists in rare gases and alkali metals. All A universal law that exists in atoms.
"Regarding the experimental phenomenon you proposed, I have thought of a good idea, but there is no time to perfect it now. After I finish the experiment at hand, we will discuss this matter together."
Stoner sighed in his heart that a genius is indeed a genius. In such a short period of time, he had already figured out an idea on how to explain this phenomenon, but he could only do experiments foolishly.
Kapitsa and Blackett, just because they hugged Chen Muwu's lap, have become a group of people in the Cavendish Laboratory who have achieved some success.
Now that time has finally turned, is it my turn to hug my thigh?
"Okay, okay! I will do this experiment well and try to give you the most accurate experimental data!"
After leaving Stoner's laboratory, Chen Muwu had no intention of going to the conference room to think about the title of the next paper, because the next paper had just been delivered to his door by Stoner personally, and now it was at his fingertips.
He turned around and entered the door of his laboratory again. De Broglie was still staring in front of the instrument.
"Louis, don't stare at the vacuum tube all the time. Please take a break for your eyes. This thing is very strong and won't break because it can't bear the pressure just because you blink your eyes."
Click——
As soon as Chen Muwu finished speaking, he and De Broglie heard the sound of glass breaking at the same time, which was somewhat unruly.
Chen Muwu was a little helpless. He just came up with an idea in the laboratory next door. Now he not only stole Pauli's luck, but also his luck?
In addition to the exclusion principle, Pauli also has an effect named after him, the Pauli effect.
Although this effect is related to experiments, it is not a conclusion drawn from physical experiments, but more like a metaphysical point of view.
Pauli may have a conflicting relationship with the laboratory. Every time he appeared in the laboratory, the people doing experiments in the laboratory would always make some unexpected mistakes inexplicably.
At a small scale, it may be a water outage, a power outage, or overexposure of photographic films; at a larger scale, it may even cause disastrous events such as fires and explosions.
His biggest achievement was that he once visited Princeton University. Princeton University burned down the only expensive cyclotron on campus that day.
Many people even jokingly put a sign on the door of the laboratory prohibiting Pauli from entering.
Hearing the sound of broken glass, Chen Muwu and De Broglie hurried forward to check. Even De Broglie ran faster than Chen Muwu.
In a weak bend, fragments and cracks appeared on the diffraction tube. It seems that the glass is not strong enough here.
Chen Muwu regretted not having someone blow out a few more diffraction tubes as backup. He had no choice but to dig out the previous drawing with specific dimensions, send it to the glass workshop, and ask the workers to help make a few more.
Chen Muwu, who did not believe in evil, took advantage of the workers to blow glass and ran to other people's experimental benches in the open laboratory and wandered around.
However, he didn't hear any complaints about instrument failure, incorrect data, etc.
This time Chen Muwu finally confirmed that he did not suffer from Pauli's bad luck because he wanted to publish a paper on the exclusion principle, and became a laboratory disaster star in this time and space.
The rupture of the glass diffraction tube just now was purely an accident.
Let me first let everyone know that you are safe.
Fortunately, it wasn't influenza A. I got up from bed in the middle of the night yesterday and ran to the bathroom several times. It was probably just a stomach flu, and I had already taken medicine.
This is an old problem of mine, and I get it every three or five times when the seasons change.
I'm a little short today, I'm lazy, I only have 6,000 words, please forgive me.
