As summer draws to a close, and the fall semester is approaching, those who had left school, or gone on vacation or returned home to visit family, were returning to Cambridge and to the Cavendish Laboratory.

Kapitsa, who was still returning by train, brought his home-filled Russian sausages and distributed them to Chen Muwu, Blackett, and his colleagues in the laboratory.

Of course, he didn't forget Ye Gongchao's part, after all, last semester, he and Blackett had been taken by Chen Muwu to Magdalen Academy to eat and drink with his compatriot.

Chen Muwu had only eaten Kharobin red sausage in his previous life, and he felt that the taste of Kapitsa brought him was similar to that red sausage, in short, it was delicious.

Kapitsa's return also made Chen Muwu's life change a little bit.

Capitsa, who had completed his Ph.D. in the summer and was no longer a student, moved out of his rented room at Mrs. Brown's house.

Cavendish Lab appointed him assistant head of the Department of Magnetics, and Trinity College hired Kapitsa as a researcher and arranged a room for him in the college.

Although the two of them can still meet in the laboratory in the future, after a day's work in the laboratory, Chen Muwu has to go home alone.

That's right, Trinity College's room arrangement, just like this workplace, pays attention to seniority, although Chen Muwu is already famous, and he has a good friendship with the dean Tom Sun, but as a new graduate student who theoretically entered this fall, he still has not been assigned to his own room, and can only continue to curl up in the upstairs room of Mrs. Brown's house.

……

When there is a loud voice in the Cavendish laboratory that sounds familiar and makes people feel a little desperate, it means that the director of the laboratory, Rutherford, has returned to the management of the laboratory after spending his long vacation on the Cornwall seaside.

After being exposed to the sun all summer, both Rutherford and his son-in-law Fowler had turned a lot redder.

Like a lion returning to the jungle, Rutherford's first act upon returning to Cavendish was to begin patrolling his territory from lab to lab and bench to bench, patiently asking his staff and students what they had achieved and made during the holidays.

After doing the experiments on visible light scattering, Chen Muwu didn't go to the lab much again.

Soon after, the lab was taken back by Chadwick, who was in charge of the overall arrangements, and diverted it for other purposes.

These days, Chen Muwu basically stayed in the Cavendish conference room, holding the typewriter in the laboratory, and typed out Chen's statistical paper and Chen Condensation's paper word by word, and now he is typing an article on matter waves.

Chen Muwu thought that the typewriter in Cavendish Laboratories was much more advanced than the one he bought when he was in the sea.

But in fact, there is no difference between the two, all mathematical formulas and special symbols should be left blank in advance, and then fill in these contents one by one with a pen after typing.

Typewriters that could print mathematical and physical symbols such as integrals, sums, and Laplace operators, as well as Greek letters, may not be developed until the sixties and seventies.

Then computer technology became more and more mature, and TeX gradually emerged, and with this convenient and fast tool, the papers of mathematicians and physicists will become more and more watery.

"Hey! Chen, long time no see! Rutherford pushed open the door to the conference room, "What are you writing again?" ”

"Director," Chen Muwu stood up, he had already heard Rutherford's loud voice a few floors through the door, "it's just a paper on electronics, and I just had a simple idea." ”

Rutherford had a smile on his face: "When I was on holiday in Cornwall, I read the book you gave me, On the Spirit of the Chinese People, and I remember that there was a sentence on it that said that modesty is an excellent character of your nation.

"Now I finally believe in this point of view, because my student Chen Muwu, although he has made great achievements in physics, still maintains the same low-key and modest as when I first met him!

"Sitting on the beach and looking at the blue sea, I occasionally wonder why you can come up with a novel idea on a steamer and finally find that scattered bright line from the experiment, when I think about a few delicious Cornish pies for lunch today?"

The scattered bright line in Rutherford's mouth is actually the first experiment that Chen Muwu did after coming to Cavendish Laboratory, about Chen scattering of visible light.

The excuse Chen Muwu gave at that time was that when he was on a steamer, he saw the blue sea and thought of Rayleigh scattering, and then thought of doing further research.

So Rutherford, who also went to the beach for a vacation, remembered to mention it when he saw the sea.

Rutherford lit his pipe, took a deep breath, and continued: "Then I saw the experimental paper you published with Capitsa and Blackett, which knocked out my most proud student Bohr.

"That's when I realized that you can see through the sea and I can't, not because I'm old, but because you're a rare genius!

"Let's talk about it, genius Chen, what interesting things have fascinated you lately?"

Rutherford's words made Chen Muwu a little embarrassed: "Director, it's still a problem caused by photons."

"I recently had a strange thought, since light with fluctuations can be seen as a particle, can something that is itself a particle also a wave? For example, electrons?

"According to the current photon theory, the momentum of a photon can be expressed as p=hν/c. Suppose that electrons are also a wave,......

“……

"Bringing this equation into the above one, we can get that the wavelength of the electron wave is equal to Planck's constant divided by the momentum of the electron, λ = h/p.

"It was such an interesting idea that I was going to write it into a paper."

Chen Muwu Luoli talked about a lot of derivation processes, but in fact, only the first few sentences are the essence.

Apparently Rutherford also grasped the point of his words: "Chen, you mean, electron is also a wave? My God, fortunately you told me these words first, if your point of view was known to the old director, his glasses would definitely fall to the ground in anger from you! ”

Thomson Sr., the previous director of the Cavendish Laboratory, was the first to discover the electron in 1897, breaking the spell of atom individusibility, for which he was awarded the Nobel Prize in Physics in 1906.

If the old Tomson, who is now nearly seventy years old, knew that Chen Muwu said that electrons are not only a particle, but also a wave, if he had not been so angry that he had a heart attack on the spot, maybe the old Tomson would really swing a golf club and hit Chen Muwu's head as if it were a giant golf ball.

Rutherford's voice, which was already loud, gradually became louder.

In other words, what he said next could no longer be regarded as a speech, but more like a kind of admonition from a superior to a subordinate who had messed up the work: "Chen, I think in your mind, don't think about these ethereal things every day, you give me the feeling that you are becoming more and more like a theoretical physicist who sits and talks about the Tao."

"But Chen, you should also know that theories aren't always so reliable.

"Please think about it carefully, you, Kapitsa, Blackett, and they only used the trajectories of recoil electrons captured in experiments to refute the incomprehensible theory put forward by your brother Bohr.

Although his theory is indeed excessive, if there is no clear experimental evidence, there may be many people who believe it.

"Mr. Chen, I hope that you will not continue to play games with their symbols like a theorist, but will engage in more hands-on experimental work and return to experiments.

"After all, in the Cavendish Laboratory, we are the ones who want to prove the true nature of nature through experiments!"

Kapitsa, who was doing experiments in the open laboratory, also heard Rutherford's loud voice.

He quipped with Blackett across the long table with a little schadenfreude: "Patrick, you see, Rao is a genius like Chen Muwu, who has been a laboratory darling for a few months, but he can't escape the crocodile's loud voice after all." ”

Blackett nodded, and it seemed that he agreed with Capitsa.

As Kapitsa said, Chen Muwu has been in Cavendish for nearly four months, and this is the first time Rutherford has lost his temper with him.

During these four months, he watched countless "live broadcasts" of other students in the Rutherford Lessons Lab as a VIP spectator.

Chen Muwu knew that the strong New Zealand man standing in front of him now was actually a tender iron man with a knife mouth and a tofu heart.

Although Rutherford is stern on the surface, in fact, everything he does is dedicated to the good of his students.

As long as you can convince him with facts and reasoning, Rutherford will always sincerely apologize to everyone he has recklessly criticized, regardless of his status.

Chen Muwu complained in his heart, Rutherford's temper is really the same as Sun Wukong's face, he can change when he says it, if he can patiently listen to others finish speaking, he may not have to apologize so many times in the future, including this time.

Chen Muwu patronized and complained about others, but he didn't want to think about how deviant he had just said inadvertently in the eyes of physicists now.

Electron, is, a, wave?

After hearing such words, who would let him continue to spread this crooked and evil way?
