Lin Yufan came to his exclusive laboratory.

It's not big or small, just thirty square meters, with all tables, chairs and props.

He first walked around the laboratory for a few times and found that it was unexpectedly clean. Although the instruments on the table looked like they had not been used for a long time, there was no trace of dust on the table, and it was obviously cleaned every day.

Then, he looked carefully at the instruments on the table.

Chen Hongwen just stood aside and nodded at Lin Yufan's behavior.

Many people look confused when they first enter a regular laboratory, or they are very reserved, as if they are visiting a friend's house, and their parents are still next to them.

Only Chen Hongwen and others with sufficient experience know that from the moment they entered the laboratory, they were the masters of this land.

As the masters, the first thing they need to do is to look at the entire laboratory, remember all the instruments on the table in their minds, and select the instruments they need to do the experiment afterwards.

Lin Yufan needed not many instruments to complete the α-particle scattering experiment, only: particle source, vacuum chamber, detector and counting system, and the last vacuum pump.

Novice scientific researchers usually encounter difficulties when selecting experimental instruments in the first level:

Although most of the talents who can become scientific researchers have rich theoretical knowledge, once they are allowed to enter actual combat, they will become like ordinary people, and they cannot even tell what the instruments are.

However, what surprised Chen Hongwen was that Lin Yufan selected all four instruments in just one minute.

"Brother Chen, I've found the instrument. Now I'm going to prepare to start the test. Can you help me turn on the main power switch in the laboratory?"

"Ah? Oh, okay, it's already opened."

"Well, the power is on, then I'll start to test it."

"Yeah... OK."

Chen Hongwen looked at Lin Yufan who was starting to experiment with some surprise.

This student is a bit weird!

It was obvious that just now, his expression and eyes were mixed with a sense of student spirit, and he felt a little unreleased.

But since he entered the laboratory, his attitude and expression have changed.

At this time, he seemed to be the master of this laboratory, who could command everything and command everything.

Here, there are no tutors and students, only instruments and experiments.

He suddenly felt that this kid named Lin Yufan had even more temperament as a scientific researcher than him!

...

In a blink of an eye, the day passed.

Chen Hongwen got up yawning. It was only seven in the morning, which was the time for his usual biological clock.

He got up and washed up, changed into his white coat, and walked towards the cafeteria.

Today's canteen is much more lively than usual, because most researchers doing scientific research here focus on experiments every day, and their lives are simple and boring.

Therefore, when I heard that some interns were coming to conduct scientific research activities, many scientific researchers immediately attracted to watch.

Chen Hongwen only drank a bowl of porridge, wiped his mouth, and began to walk towards Lin Yufan's laboratory.

Yesterday, Lin Yufan didn't even eat lunch and devoted himself to the α particle scattering experiment. Although he failed many times due to his unfamiliarity with experimental instruments, in Chen Hongwen's opinion, his experimental ideas and general direction are correct.

The success of the experiment is only a matter of time.

According to yesterday's progress, Lin Yufan will probably be able to complete the α particle scattering experiment on the third or fourth day, which is already very remarkable for a new scientific researcher.

However, when he opened Lin Yufan's laboratory, he couldn't help frowning because he found that the lights in the laboratory were on.

He poked his head out and saw that Lin Yufan was indeed lowering his head and doing the experiment with concentration.

It seems that he should have arrived before dawn.

Chen Hongwen walked into the laboratory and was about to ask, but Lin Yufan didn't even raise his head and said first:

"You help me move the table in front of you a little to the right, and close the door. The light is too high, which can easily lead to errors in the experiment."

The day after entering the laboratory, his tone of speaking was no longer as polite as before, and it was more like a commanding tone.

Chen Hongwen moved the table a little to the right as he said, then closed the door, and finally his eyes fell on his meticulous cheek.

He sighed slightly in his heart and sighed: This is another amazing person to appear.

Chen Hongwen's work is the most boring among the ten mentors.

Other tutors are busy guiding students every day, providing experimental ideas, watching the students they teach, and tirelessly performing experiments, everyone is fulfilled and relieved.

However, when Chen Hongwen came, he not only did not have to guide students, but he didn't even have time to interrupt. He occasionally had to help with odd jobs, moving tables, chairs and dinner.

This day is so sad!

At 6:30 pm, looking at Lin Yufan who was burying his head in the experiment, Chen Hongwen stood up and prepared to help Lin Yufan get a meal back, and by the way, he also solved his dinner today.

Alas, there is no way, my students are too outstanding, so I, a teacher, can only run errands.

Look at other tutors, who are not students who are attentive and come back to get food for the tutor. When he arrives here, his tutor is going to help the students get food.

It turns out that the Yangtze River is pushing the previous waves, and the previous waves die on the beach. The ancients really did not deceive me!

However, when he was about to open the door, Lin Yufan suddenly raised his head and said, "Brother Chen, are you going to have a meal?"

Chen Hongwen nodded and said, "I see that you are just immersed in your experiments. I plan to go to have a meal first, and then pack and bring you a copy."

Lin Yufan was stunned when he heard this, smiled and said, "No need for Brother Chen, let's go together."

"Uh," Chen Hongwen glanced at the table and said, "It's okay, you can do the experiment first. It's just a meal, it's nothing to worry about."

"Brother Chen, I don't mean that. I didn't be polite to you two." Lin Yufan clapped his hands, touched his already rumbling stomach, and said with a smile: "I mean, my experiment has been completed and I can go to the cafeteria to have dinner."

"It's done?"

Chen Hongwen was shocked and hurried to Lin Yufan's desk, meticulously checking the various instruments on the table.

He pointed at a golden target and deliberately threw down a trap problem:

"What's the reason why you changed the thickness of this gold target?"

Lin Yufan took a look, but was not fooled:

"Before changing the thickness of the gold target, I first fixed the scattering angle here, and then verified the linear relationship between the scattering count rate and the thickness of the gold target. On these three pages are the data and linear diagrams recorded during my experiment."

Chen Hongwen stared at the data for a long time and nodded.

Lin Yufan's verification is completely valid!

He thought about it, then deliberately looked for trouble and said, "I think you seem to have changed the particle source of α, and I think this step is completely unnecessary."

Lin Yufan shook his head and said negatively: "I changed the particle source of α to change the energy of the particle, and used to verify that the scattering count rate is inversely proportional to the square of the energy of α particles. The five pages here are the data and line charts I recorded."

Chen Hongwen looked carefully for a long time, and the result was once again completely true!
Chapter completed!
