Chapter 67 Part 2

Chen Jun wiped his face. He picked up the basketball that had rolled into the corner of the court. He stood proudly outside the three-point line, and threw it in an elegant way.

He missed.

But he didn’t care at all.

The goddess… actually liked him?

No wonder! In fact, there were already signs.

For example, yesterday, when he went to ask questions from the boss, Goddess Zhang seemed to be looking at them with a gentle and adorable look. It also held a bit of affection. As a result of that, as soon as his eyes met hers, she quickly looked away.

He must have caught her peeping at him and she felt embarrassed.

God! Since the goddess liked him, then they were made for each other, right? The goddess was shy even when she looked at him, and she must have thin skin. She must have given him the difficult task of confessing to her!

Chen Jun puffed out his chest. At this moment, he felt that he had grown up and was a responsible man.

He looked at his two good brothers and declared, “I plan to confess this Friday. Once we become an item, it’ll be the goddess’s birthday on Saturday and I can spend it with her. Brothers, help me!”

After hearing what he said, the two boys looked at each other and nodded a lot, their eyes serious.

Chen Jun couldn’t stop his nose from sticking up and patted both of them on the shoulder.

They were worthy of being good brothers, and they were willing to help no matter what.

……

On Thursday night, Li Wei gave the first lesson to the competition class.

He reexplained the angular momentum theorem and rigid body rotation.

It was his first time giving a lecture, and he didn’t seem to give off any feelings of inexperience at all. The youth standing in front of the blackboard was much taller than Lin Pingzheng. The students sitting down suddenly felt that the blackboard was somewhat shorter compared to before.

The youth’s sleeve was pulled up. His neat and strong hand was holding the chalk, and he wrote several formulas on the blackboard. It was all the variables used in this topic and their relationships: momentum p, angular momentum L, torque M, rotational inertia I…

After he finished writing, he drew a regular circle behind each one and put labels on it.

After he did that, Zhang Man saw him turn around and looked at her as if she had smiled.

Next, the youth summarized the questions that the boys had asked him in the previous period, as well as his own basic solutions into several categories.

Then, he began to disassemble the question and the diagram.

He extracted the required information in each question and the corresponding position in the diagram. He wrote the variable at each corresponding position.

After that, he wrote down the variable according to the known conditions from the question and wrote down a series of relevant formulas.

Whether it’s a thin rod, spring, string, ball, or inclined plane, different properties made them have different stress types. Soon, several topics were analyzed, and the objects that caused everyone a headache were transformed into physical symbols.

In this way, a complex physics problem went from an abstract question into a bunch of physics variables and their relationships.

Simple, clear, and understandable.

Chen Jun blurted out, “What the f**k!”. He was saying what everyone was thinking.

How could he solve the question like this? Those diagrams and the root of the problem had been simplified for the moment. They were clamoring to determine which parts they knew, which variables to use, and which formulas to follow. All complex variables were at the top corner of the blackboard.

There was nothing missing.

It… it felt like they had a huge tangled up ball of yarn in their hands, and what he did just now was find where the yarn started and easily smooth out all the tight knots.

Wasn’t it too cool?

The whole classroom was very quiet, just like when Lin Pingzheng was there. However, the difference was that when he was here, it was a dead silence. Now, everyone’s eyes were lit up. They were writing at top speed to copy what was on the blackboard, and there was no time to speak in the silence.

Fifteen minutes later, after the question was done, everyone looked brightly at the boss in front of the blackboard.

“Just now, these are mathematical analyses for several basic categories. Of course, the real physics model is very complex, and this set of methods is not applicable to all topics. Therefore, I hope everyone can truly understand the meaning of each formula from a physical perspective.”

“This discipline is not just about computation.”

As the youth spoke, he began to explain the important physics part of each topic and the formulas using various models.

He explained the relationship between angular momentum and torque, the relationship between angular momentum and momentum, how to understand the differential and integral processes involved in reality models, and what kind of properties are in rotational inertia for a system of particles…

The formulas that were originally memorized and mechanically applied suddenly became alive under his explanation. It was no longer a forbidden written mathematical derivation, but a living physics image that moved with each sentence he uttered. It visually and elegantly spun and danced in front of everyone.

This was physics.

While it was necessary to use mathematics as a tool for derivation, it was required to have a  deeper understanding of what physics meant.

Many years later, when Chen Jun, who was a small name in the academic field of physics, was lecturing to his students about “mechanics” in a college class, he suddenly remembered the lesson he had in a narrow classroom when he was a teenager.

The young and promising young professor, facing more than a hundred students in the lecture hall, suddenly got stuck.

Over the years, he could still feel his heart beating faster during that moment.

In a time where people only pursued exams, the talented youth set aside derivation and used plain language to tell them about the world of physics, constructing a vivid image and framework.

Obviously, in today’s point of view, it was very basic and simple content, but it made him feel at that time—

It turns out that physics is this beautiful.
