I failed a course, and the system became my study supervisor.

Chapter 28 First Intensive Training

Xu Ling returned to school, but the Qingming rain had not stopped yet.

Zeng Boyuan finally notified all the contestants to start the first concentrated training.

Wednesday at 1204: p.m., First Teaching Building, Classroom .

The first teaching building!
This teaching building is a physics experimental teaching center specially built by the school, which is equipped with various basic experimental equipment.

Xu Ling took his university physics experiment course here.

……

"Please ask the leaders of the two groups to report on their group's topic selection and explain the reasons for the topic selection. The first group, please go first."

After saying that, Zeng Boyuan walked down and left the podium to the students.

"Our group's top choice was the 'ping pong rocket' problem. This problem involves placing a ping pong ball in a container of water. When you lower the container, the ball is launched into the air.

We need to study the factors that affect the height of a ping pong ball and make it fly as high as possible with 2 liters of water.

We chose this problem because it is relatively easy and we already have a preliminary solution."

Yu Wenkai, the leader of Group 1, gave a concise and to the point speech.

"What are your alternative topics?"

Liu Chunlin continued to ask.

"Our candidate topics are water drop lens, contactless resistor, elastic rotation of rubber band, rigid ramp walker, and magnetic levitation problem."

Yu Wenkai added.

"Yes, these questions are all very appropriate. Let's do the experiment seriously!"

Zeng Boyuan nodded in approval.

Great minds think alike. The first group had two overlapping questions with Xu Ling and his team.

"Leader of the second team, please come up."

Xu Ling immediately stood up and strode up to the podium.

But he still felt a little nervous, even though there were only about ten people in the audience.

Facing everyone's gaze, Xu Ling slowly spoke, his voice trembling slightly:
"Our top priority is the water drop lens problem. We considered it from multiple perspectives, including the difficulty of experimental operation and optimization, the difficulty of theoretical derivation, and the value of theoretical research."

As soon as he opened his mouth, Xu Ling's speech became fluent and his previous nervousness disappeared.

Xu Ling continued, "One of our candidate problems is the same as the first group, which is the magnetic levitation problem. The other problems are detecting the number of small balls in a blind box, the sound produced by bending a large thin plate, and the power of a juicy solar cell."

"Excellent!" Liu Chunlin encouraged, then changed the subject, "Compared to the first group, your second group is much less experienced. I'm curious about your topic selection process."

"Well... we also encountered problems in the beginning when it came to choosing topics. It felt like every question was like a hedgehog, with thorns everywhere you scratched.

Afterwards, through brainstorming, each person chose a question they thought was good. Finally, we reached the final result through a management-based decision-making method.

Xu Ling organized his words and spoke slowly.

"Haha! That's right! Interdisciplinary research is the right thing to do. Often, applying methods from one discipline to another can produce unexpected results. This is something worth learning!"

After hearing this, Zeng Boyuan was very satisfied and kept praising it.

"Okay, we've written down your questions. Now, you should know why we called you here."

Zeng Boyuan continued.

"Are we going to decide on the laboratory today?" Xu Ling asked excitedly.

Zeng Boyuan smiled slightly and said, "That's right. Today we will determine the laboratory based on your selected topics, and then assign a teaching assistant to each of your groups."

For a moment, the audience was in an uproar, and even the experienced third-year students were excited.

After a moment, Zeng Boyuan stretched out his hand and pressed it in the air, saying:

"Everyone, please be patient! We have handed over your first and alternative topics to the laboratory teachers, and the laboratory for the first choice topic will be determined today!" Now, Xu Ling was even more excited. Although he had been to many laboratories for physics experiments, could they compare with this one?

This is my first experiment!

"Okay, students! Now, the first group will follow me, and the second group will follow Teacher Liu. We will first show you around the lab."

Zeng Boyuan once again said something inspiring.

……

Following Liu Chunlin's footsteps, Xu Ling and other members of the team, with excitement and anticipation, took many turns and finally arrived at the long-awaited laboratory.

1402: Optical Laboratory (I)
When you push open the door, you will see many different types of optical instruments placed in the laboratory, but it does not look messy.

Among the many instruments, the only ones Xu Ling could name were the spectrometer, laser emitter and microscope.

But most of these experimental instruments cannot be used in their experiments.

In addition to some instruments in the laboratory, there was also a young man waiting there, who should be the teaching assistant.

"Hello everyone, welcome to the lab. I'm He Jiangran, your teaching assistant for optics experiments."

He Jiangran introduced himself with a smile.

Everyone instantly developed a favorable impression of him.

Because he not only speaks well, but is also quite handsome.

He is nearly 1.8 meters tall, with a straight body, three-dimensional facial features and bright eyes.

"Then Teacher Xiao He, I'll be leaving now. I'll leave the children to you."

Liu Chunlin gave a few instructions and left the laboratory.

Now the whole room has completely become the territory of young people, and the atmosphere is very active and relaxed.

"The experiment you're going to do is a water drop lens, right? Today, I'll first familiarize you with some of the relevant instruments. After you've prepared your experimental plan, you can choose the components yourself."

After saying that, He Jiangran led his team to the experimental equipment rack.

"This is a common LED light source. You will definitely need it."

"This is a regular light microscope, and you can use it to see the scale of imaging."

"If you want to measure the size of an image, a microscope alone is not enough. You need to replace the original eyepiece of the microscope with this micrometer eyepiece."

"Here are the brackets and clamps."

"This is a resolution test board with different line widths."

……

He Jiangran introduced almost all the experimental instruments on the experimental equipment rack.

Everyone was confused. Many of the small devices looked similar, but their names were very different.

But Xu Ling was cautious. While He Jiangran was introducing the device, he was thinking about whether the device could be used.

After He Jiangran finished his introduction, Xu Ling had already made up his mind about the outline of his speech.

"Okay, I've almost finished introducing everything. You can come over anytime in the future. The door won't be locked.

But I suggest you come together, because the experiment is a collaborative effort. Let me know if you need any help. Add me to your group chat later.

That’s all for today, thank you all for your hard work.”

After saying that, He Jiangran joined the group and left the laboratory.

The team members did not stay in the laboratory and left as well.

The design of the experimental plan can be discussed online; it’s not a big problem.
