Of course, there is another point. The two of them are very curious about how to use the object that Cheng Chubi gave to these two mathematics masters, which he called the abacus.
Cheng Chubi took the book and was surprised when he saw the page Zu Guang opened.
"Have you solved all the previous questions?"
Seeing Cheng Chubi's surprised look, Zuguang and Hu Yonglin couldn't help but have a look of pride on their faces.
But when their eyes fell on the book again, they saw that they and others had spent so many days working and were still stuck on the first third of the book.
That trace of pride instantly disappeared without a trace, Zu Guang stroked his short beard and said loudly.
"It's just a fluke..."
Cheng Chubi took the manuscript of their problem solving handed over by Hu Yonglin, compared it with the problem, and praised it.
"No, it's pretty good. After all, the two teachers are not very proficient in the application of these numbers and formulas..."
"As for this problem you encountered, what do you think?"
Zu Guang thought about the words and explained. "Zu always feels that this question is too profound.
Zu has never considered that throwing stones can actually be calculated..."
Zhang Wenchang, who was on the side, couldn't help but interject. "Zhang considers himself to be of limited talent and knowledge. He has been thinking hard for a long time and feels that this question is simply unsolvable."
Cheng Chubi looked at the three people in front of him, patted the book in his hand and said with a smile.
"Actually, this question is a bit out of line for some of you. To be precise, this is not a math question, but a physics question."
"Physics question?"
"Exactly, the so-called physics is a discipline that studies the general laws of material motion and the basic structure of matter.
The most basic forms and laws of movement of all matter, from the universe to elementary particles."
"And its theoretical structure mainly makes full use of mathematics as its working language."
Cheng Chubi sat down, took a piece of paper, and picked up a quill pen. Following the question, he started to list the parametric equations...
Everyone looked at him blankly, watching him explain the functions of those parametric equations.
As well as flight time calculation formula, range calculation formula, launch angle calculation formula...
And he also drew a two-dimensional curve of the stone trajectory...
In short, everyone is confused in the ocean of physics and feels suffocated.
Cheng Chubi also picked up the abacus, moved the abacus flexibly with his fingers, clicked it, and finally wrote down the results.

After Fang Jun was stunned for a long time, he was the first to ask the question in his mind.
"Brother Chu Bi, what is the use of this calculation in your physics question?"
Cheng Chubi gently poked his fingers at the results he got after checking and explained.
"My dear brother, may I have forgotten that among the weapons of the Tang Dynasty, including crossbows, catapults, and bows and arrows, the range can be calculated based on these formulas."
"In this way, if we, Datang, want to develop better, more powerful, and more efficient long-range weapons.
You can also go through repeated calculations like this before making it..."
"From the perspective of physics, we understand that we must be objective and fair in dealing with things, and any conclusion has its conditions and scope of use..."
Zuguang, Zhang Wenchang, and Hu Yonglin stared blankly at Cheng Chubi who was talking eloquently.
They felt more and more that the knowledge they had learned seemed a bit too shallow compared to Cheng Chubi.
After a long time, Zuguang exhaled a breath of turbid air and bowed respectfully to Cheng Chubi, holding the crown on his head.
"Thank you to the principal for clarifying our doubts. After listening to the principal's words, Zu finally understood what physics is. In physics, everything has its own reason..."
“I don’t know, I don’t know if the principal, Mr. Zu, will open this department in the university, haha...”
He looked at this math master who was talking nonsense in front of him and was full of desire for physics.
Zhang Wenchang and Hu Yonglin also looked at Cheng Chubi eagerly, as if they were afraid that he would reject them.
"If a few of you are willing to learn physics, it would be easy. When I have time, I will compile some physics stuff and study with you."
"If there is an opportunity in the future, I might bother you all to teach students so that more people can understand physics."
The three of them couldn't help being overjoyed and saluted Cheng Chubi again, and Cheng Chubi quickly returned the salute.
Next, they curiously asked about the abacus given to them by Cheng Chubi, with the guidance of Cheng Chubi, a master of practical operations.
Coupled with their intelligence, they soon understood the magical effect of this abacus.
Especially these three math experts were so excited that they didn’t know what to do.
"I think I have been studying calculation since childhood for more than 20 years. I have always felt that planning is a bit too complicated, but there is no more convenient method."
"Principal Cheng, you have developed this thing. It is simply a sharp tool for us to use in arithmetic, baby."
Zhang Wenchang's eyes were a little green, and he wished he could reach out and grab a handful of this treasure. Unfortunately, everyone was a polite person, and they were old acquaintances and were too embarrassed to take action.
Zhang Wenchang could only look at Cheng Chubi, squeeze out a flattering smile and said.
"Principal Cheng, I wonder if Zhang can replicate such a mathematical tool?"
"It turns out that Teacher Zhang is also a master of mathematics. This is really an oversight on the part of Cheng."
"I have already prepared some for the students in the mathematics department of our school. If there are any extra, I will ask someone to give some to Teacher Zhang later."
#####
After the three mathematics masters left, Li Ke approached Cheng Chubi with a resentful look on his face.
"Brother Chu Bi, since you have such a good treasure that is good for arithmetic, why don't you let me know?"
"You didn't ask." Cheng Chubi rolled his eyes at the guy unhappily.
Cheng Chubi had invented the abacus a long time ago, and it was used in the accounting room of the old Cheng family.
Now that I have considered that since my university wants to engage in mathematics, physics and chemistry, it naturally cannot lack computing tools.
Cheng Chubi had just a few dozen of them made, and they would be promoted among students. The reason why they were brought here today was to show off.
The purpose is to let these teachers learn it first so that they can teach students later.
"Then I want one too. My accountant will definitely be happy to use it too."
"There's me, I want it too." Although Fang Jun was not as obsessive as Li Ke, he was not stupid at all, and he immediately shouted loudly.
At this moment, Cheng Chubi and Li Ke both focused their attention on Fang Jun.
"I said Brother Jun, what do you want with this thing?"
Being stared directly at by these two guys made Fang Jun feel a little stressed. He scratched his head. In fact, Fang Jun still told the truth.
"I took it and learned it so that I could teach my father."
