Top Student

When there was no class on the weekend, Xu You decided to visit Wang Xiangwu's laboratory.

Wang Xiangwu and Xu You said before that there is a doctor named Zhao Weijia in the laboratory, who is in the laboratory every day.

No matter working days or holidays, almost all year round.

At most, it's just a few days at home during the Chinese New Year.

When you get to the laboratory, just go to Zhao Weijia.

At eight o'clock in the morning, Xu You arrived at the door of Wang Xiangwu's laboratory.

"Hey, why didn't you open the door?"

Xu You was not in a hurry either, and stood there waiting for a while.

More than ten minutes later, a man walked over slowly with a key in his hand.

And stopped in front of Wang Xiangwu's laboratory.

Xu You glanced at the man.

Fat body, thin hair, sloppy clothes, listless.

It is not the same as the doctor image in Xu You's fantasy.

"Hello, is this Dr. Zhao Weijia?" Xu You asked tentatively.

"Yes, you are?"

"Hi brother, my name is Xu You. Professor Wang Xiangwu asked me to come to the laboratory for an internship."

"Oh, I remembered. Teacher Wang told me. Let's go in together."

Zhao Weijia is not surprised by this.

Occasionally, Wang Xiangwu would indeed find some outstanding undergraduates to visit and practice in his laboratory.

After entering the laboratory, Zhao Weijia was eating buns while turning on the computer.

He didn't pay attention to Xu You's meaning.

Xu You didn't ask any more questions, but stood aside, looking at the environment in the laboratory.

Various experimental equipment that have only been seen in books and the Internet before.

Xu You finally had the chance to witness it with his own eyes.

In the excitement, Xu You even wanted to touch those attractive experimental equipment.

But Xu You knew that since he had just arrived in the laboratory, he could not touch the experimental equipment casually.

Zhao Weijia didn't deliberately snub Xu You, but because his scientific research tasks were really heavy, he had to run the equipment and programs first.

It wasn't until after all the preparations were done that Zhao Weijia remembered that there was someone like Xu You in the laboratory.

Zhao Weijia knew that those who could be invited to the laboratory by Wang Xiangwu were all excellent undergraduates.

But no matter how outstanding it is, it is definitely incomparable with a PhD with rich scientific research experience.

Zhao Weijia decided to test Xu You a little bit, so that future juniors can realize their shallow knowledge.

Only then can we learn in the laboratory with an open mind.

"Is this your first time in the lab?"

"Yes, the first time."

"Seeing these things, you feel very strange, right? It's okay, it's the same when I first came here, I don't know what is what."

In fact, although Xu You saw these devices for the first time, most of them could be called by their names.

But since Zhao Weijia said so, Xu You couldn't refute anything.

"Come on, let me show you the subject I'm researching. Can you see what I'm researching?"

Zhao Weijia knew that it was impossible for Xu You to know what these things were.

Wait for Xu You to shake his head in a daze, and then explain it to him.

It is one of Zhao Weijia's few pleasures to let the younger brothers and younger sisters feel the profound knowledge of the seniors.

Xu You looked at the content on the screen, and probably understood what was on the screen.

"Brother, if I remember correctly, this should be the phase and wavefront distribution of the optical vortex."

Zhao Weijia was taken aback when he heard this.

"How do you know all this?"

Zhao Weijia's research direction is rarely researched in the whole country.

Only a few laboratories, including Ji University, will study this direction.

"I read it in a book before, so I remembered it." Xu You said truthfully.

When studying Wu Jing, Xu You had read nearly a hundred books.

Although there are some things that I don't understand very deeply, I still know a little bit about it.

"Then let me ask you, what method should be used to prepare the optical vortex?"

Although disturbed by Xu You's answer, Zhao Weijia quickly stabilized his emotions and continued to ask questions.

Originally, Zhao Weijia did not intend to ask such a difficult question, after all, for undergraduates, this question is too superficial.

Zhao Weijia just wanted to wait for Xu You to shake his head before explaining to Xu You.

"The method of adjusting the phase can be used. The most direct method I remember is to use a helical phase plate to forcibly add a helical phase to the fundamental Gaussian light field, so that an optical vortex can be obtained."

"Then what if there is no spiral phase plate?" Zhao Weijia asked again.

"Hmm... You can also add a fork-shaped diffraction grating to the spatial light modulator to generate a spiral phase." Xu You rolled his eyes, trying to recall.

"Then what's the difference between these two methods!" Zhao Weijia became anxious.

"The first method only modulates the phase of the incident light field, and is not selective to the polarization. The second method, which realizes the phase modulation function for a specific polarization of the light field, is selective to the polarization."

After Xu You answered again, the air in the laboratory seemed to freeze.

For a while, Zhao Weijia didn't know what topic to use to make things difficult for Xu You.

"Brother, did I make a mistake in my answer?"

Seeing that Zhao Weijia didn't speak, Xu You thought that his answer was wrong.

"No...the answer is quite good. The theoretical knowledge is quite solid."

It was the first time Zhao Weijia encountered a setback in front of his junior brother, so he could only smile awkwardly.

Not to mention undergraduates, even Zhao Weijia couldn't answer these questions when he was studying for a master's degree.

"Sophomore or junior?"

Zhao Weijia knew that freshman students would not take Wang Xiangwu's class, so he subconsciously thought that Xu You was at least a sophomore student.

"Freshman at the beginning of school."

"Freshman?" Zhao Weijia asked puzzled.

"I was recommended through the competition, and I will officially enter the school next year, and I will attend some courses in school in advance."

Hearing Xu You's answer, Zhao Weijia was even more puzzled.

How could Wang Xiangwu let a high school student come to the laboratory for an internship?

However, after reading Xu You's answer just now, it is true that the foundation is very solid.

From the looks of it, this kid still has something special about him.

Fortunately, Xu You is only a high school student after all, and he still doesn't understand many things in Zhao Weijia's thesis.

This finally gave Zhao Weijia a chance to show off his knowledge.

After all, Zhao Weijia has a Ph.D. in physics from Ji University, and many things cannot be known without a long-term scientific research process.

Xu You listened carefully to Zhao Weijia's explanation, and nodded repeatedly.

This made Zhao Weijia's impression of Xu You better and better.

Not only the theoretical foundation is good, but also there will be no pride.

Another thing that surprised Zhao Weijia was.

At first I thought Xu You was just here for a visit.

In the end, like myself, I stayed until ten o'clock in the evening.

It wasn't until he left that Xu You left with him.

From then on, whenever Xu You had time, he would often come to the laboratory for internship.

Zhao Weijia will also explain her various knowledge and experiences to Xu You when she is not busy.
