Scientists should be mobile, and scientists can't stay in the same place all the time.

You see, scientists in California and scientists in New York State are talking to each other, and the sparks of ideas are rubbing and rubbing, and maybe new scientific results can be born.

"The problem now is that we don't get the silver pattern." Woodgate said distressedly, "Robert, you're the best experimental physicist in America, give me some advice, yes, I need your advice." ”

Milligan said solemnly: "William, do you really believe that atomic orientation is a real existence in physics? It seems to me that it's just a recipe for calculations--- a timetable that describes electrons, you know what I mean? ”

As if struck by lightning, Woodgate trembled violently.

Scientist-to-scientist academic conversations don't need to be specific to each operator or each experimental component.

Woodgate understood exactly what Milligan meant, at first he rejected it, gradually he tried to accept it, and finally, he was confused, he didn't know whether to refuse or accept.

Woodgate's fierce intellectual struggle is like modern physics in the first half of the 20th century.

The history of modern physics is a history of battles, in which various schools of thought struggled continuously, and the victors unified their thinking and taught and educated people, and the physics textbooks we studied in the second half of the 20th century and the 21st century were compiled by these academic victors.

The academic losers, with their academic ideas defined by the victors as "ridiculous" and "devilish monsters", quietly and silently disappeared in the long river of rolling waves.

It is said that Li Kangping returned to the laboratory and found that the academic atmosphere of their team had undergone subtle changes overnight.

"Perhaps we should consider new experiments, such as designing an experiment that would measure Planck's constant, which is more accurate than Robert Milligan's version." Woodgate made a difficult decision.

Alan asked in surprise, "Professor, are you kidding?" ”

Li Kangping was also confused: "I don't think it's funny. ”

"I'm sure I'll be able to measure a more accurate Planck constant, and if we're lucky, we'll be able to measure a new Planck constant within the year, or early next year at the latest. At that time, you will also get a master's degree. "And the experiment of space quantization, to be honest, I don't know when it will be done, I can't estimate the exact time, 1921, 1922, even 1930, it's all possible." ”

"Lee, Allen, you know, in the United States, everybody is realistic, and the divorce rate continues to climb, what does that mean? Explain that if there is no hope in love, then give it up and start the next love as soon as possible. Even love has suffered from this shocking reality to the point of vomiting, why should we stubbornly hold on to a thing that has no hope? ”

Li Kangping said loudly: "Professor, please tell me, can love be compared with science?" I don't care if love is cheap or priceless, I just care about my science! ”

Alan yelled, "Hey, Lee, watch your tone!" How can you talk to a professor with such an attitude! Who do you think you are, because you advocate science? No, no, you shouldn't be like this, please calm down! ”

"Who initiated the space quantization experiment? It's a professor! Who is busy raising money and equipment? It's a professor too! Who put the most effort into this project? I'm still a professor! ”

"How could a professor abandon the project if it wasn't a last resort? Having abandoned this project, who is the saddest? It's a professor too! ”

"So, Lee, please understand the professor's distress! I believe that the professor made this difficult decision after careful consideration! ”

Allen yelled emotionally, and his grievances for the innocent professor seemed to be a catharsis--- a catharsis that he had been working for nothing for months.

The United States is a country that has gained independence through resistance to colonial rule, and forbearance and implicit have never been a compliment in the United States, and the spirit of resistance to authority is deeply imprinted in the soul of Americans.

It is very difficult to be a leader in the United States, and if a leader makes a decision that his subordinates think is wrong, his subordinates may rebel against the leader in the most direct way.

The rebel in the lab was Li Kangping, who was not an American citizen, but who knew the American spirit well.

The professor allowed Li Kangping to resist, and the professor insisted on his academic decision.

"Let's take a few days off and adjust our mood. Next Monday, we will launch the Planck Constant Project. "Lee, you can follow me on a new project, or you can switch to a mentor at Columbia or another university. If it was the first option, I would be happy. If it's the second option, I'll connect you with other tutors. ”

In general, most of the American physicists that Li Kangping came into contact with were people who talked about things on their own merits.

Academic controversy is unavoidable, and it is the basic principle of American physicists.

Of course, a small number of American physicists and scholars in other fields are also right for people, or only people for things. Dealing with this kind of scholar must be in PlanB--- kill combat mode, and never die.

Dealing with Professor Woodgate, Li Kangping still adopts a gentle PlanA.

The professor and Allen left the laboratory, and Li Kangping remained here.

Li Kangping looked at this set of equipment, he fully understood Professor Woodgate's hard work, and he even sympathized with the professor.

Professor Woodgate realized as early as 1919 that an attempt should be made to prove the theory of space quantization.

However, it is Bohr and Sommerfeld who have gone down in history to the names of those who proved Bohr's and Sommerfeld's theories.

Physicists, such as Professor Woodgate, are mostly reduced to cannon fodder.

You can't be cannon fodder, absolutely not.

Li Kangping checked the equipment again, and he stayed up all night until the next morning, and he came to a conclusion that seemed to make him laugh and cry: "Could it be that the aperture size is wrong and the interval is too long?" ”

We kept an eye on Ace, King, and Queen, such as the vacuum system, the magnetic field system, and the silver atom beam generation system, and these big names teased us for months, causing the professor to break his arm, Allen to hang his head, and I, having a fight with them, faced the embarrassing situation of choosing a new mentor.

Through my continuous observation and summary, I unexpectedly found that it is not the big name that determines the victory, but it may be "Square Slice 3"!

Hades is easy to provoke, and the little ghost is difficult.

Oh, this damn "Square Slice 3"!

Li Kangping couldn't sleep with excitement, but he had to get a good night's sleep.

With the help of half a bottle of vodka, Li Kangping forced himself to sleep.

I slept for a long, long time, as if it had been a century.

At six o'clock in the evening, Li Kangping got up, and after eating and drinking, he rushed to the laboratory.

There is a round hole with a diameter of one millimeter in the grille plate, which is the exit hole of the silver atom beam. Theoretically, a beam of silver atoms shot out of this one-millimeter hole could hit the glass plate directly, creating a silver layer pattern.

This plate is one of the least valuable pieces of laboratory equipment, and we have not paid enough attention to it in the past few months.

Li Kangping chose a new steel plate with no holes, which was very thin, and could be made with ordinary tools.

Zizi.

Li Kangping carefully made holes in the steel plate.

To be exact, what he opened was not a hole, but a right-angled slit 0.8 mm long and 0.04 mm wide.

Li Kangping installed a steel plate with a right-angle seam 0.8 mm long and 0.04 mm wide.

The distance between the steel plate and the glass plate should be kept at 2.5 cm, and the distance between the two platinum sheets should be adjusted to ...... Well, I think about it, let's adjust it to 3.3 cm first.

Li Kangping dismantled the vacuum system, shortened the interval between the two platinum sheets inside to 3.3 centimeters, and then reinstalled the vacuum system.

"The first experiment after the third adjustment of the Woodgate team's space quantization experiment was launched."

Li Kangping, who was fighting alone, turned on the experimental equipment, he did not dare to guarantee that the effect of this experiment would be better than the previous one, what he could do was to wait for 16 hours, and if the result was not satisfactory, then change it to a very ideal one--- before the next Monday.

There are only a few days left until next Monday, and there is not much time left for Li Kangping.

It was late at night, and Li Kangping focused on operating the equipment.

Magnetize, magnetize, magnetize!

After three magnetizations, the magnetic field with an unevenness of 10^4 gauss per centimeter operates stably.

The night is deeper, and the single-handed experiment is doomed to loneliness alone.

"The inevitability of truth, and even the special certainty to which it is revered, is only an illusion."

The lonely Li Kangping spoke to himself in German—a sentence from Riemann.

The morning sun always hangs in a fixed place at a fixed time, and thick clouds block the sunlight.

At noon, a light rain fell from the sky. Li Kangping removed the glass plate and placed it under a microscope.

Come out, come out, don't let me down again.

Li Kangping took a deep breath, then closed one eye, and the one that opened looked through the eyepiece for a special certainty.

If it weren't for Li Kangping's dazzle, then it would be the silver atom beam who bowed his head and confessed.

Li Kangping observed that a silver layer pattern appeared on the glass plate!

A cunning beam of silver atoms, it finally shows the fox's tail!

The pattern is more vague, and the fuzzy pattern consists of two bands on the left and right, which are asymmetrical, and in the middle there is nothing.

"Tell me, did I succeed?"

"That's right, I made it, I made it!"

Li Kangping turned off the equipment, and he left the laboratory and ran wildly in the drizzle.

"Sir, I did!"

"Dude, I really did it!"

Li Kangping told everyone he met the good news.

"Congratulations, young man!"

"Congratulations, sir!"

Passers-by on the campus of Columbia University sent congratulatory messages one after another, they did not know exactly where Li Kangping succeeded, but what does it matter, he did it, so he should be congratulated.
