When they heard this, they instantly agreed.
For the past few days, Zhang Feng had been busy doing something unknown. Zhang Feng had told them about these things before, but they had already returned it to Zhang Feng in their f * cking dreams.
At this time, Zhang Feng had told them not to say anything.
This made them feel extremely miserable. They went to look for Ma Zhou and the others. Feng Zi had actually ordered them to keep their mouths shut. Whoever dared to say anything would be beaten up. This was unbearable.
In the past few days, the water wheel had been built.
However, they did not know where it went wrong. If there was not a problem here, there must be a problem somewhere else. This made them so anxious that they could not stop even if they wanted to.
What was worse was that Feng Zi refused to say anything even if he died.
On the other hand, their father and the people from the Ministry of Works had come to ask several times.
Seeing that the time to hand over the phosphate fertilizer was almost up, if they could not get it done by then, forget about being admired by tens of thousands, they might as well be beaten fifty times first …
At this time, it was obvious that this classroom was a place for physics classes. At this time, Zhang Feng could actually come. Presumably, even if he did not want to teach in front of so many people, he could not bring himself to do it, right?
Hehe!
The few of them smiled knowingly.
At this time, Lao Tzu being shameless was better than not being able to hand over the stuff and being beaten up by their father and the Emperor, right?
"Move aside, move aside!"
"All of you, move aside for Lao Tzu!"
Cheng Chumo's loud and rough voice exploded in an instant, making the students a little fearful. They instinctively moved aside to make a path.
The crowd did not dare to delay in the slightest and did not dare to offend these people.
Zhang Feng, who was in the classroom, also heard the voices outside the door.
He knew that his arrival would attract a lot of students. After all, this was his first time teaching in a classroom. Naturally, the students would flock over.
However, he did not expect that so many people would come.
Moreover, these people finally could not hold it in any longer.
Thinking of this, Zhang Feng also temporarily put aside the idea of preparing the lecture. He waved his hand and asked the students to open the front and back doors as well as the windows.
In an instant, the students outside the door rushed into the classroom in excitement. Originally, the classroom was designed according to the classroom of the future. A classroom could accommodate 60 people without feeling crowded.
In an instant.
All the students in the classroom could no longer sit still. Even the old Xiucai and Hao Chujun were forced to stand on the podium. They didn't know whether to laugh or cry as they looked at the classroom and Ma Zhou, Cheng Chumo, and the others who were still squeezing in.
Cheng Chumo, Zhangsun, Wei Shuyu, and Yuchi Baolin valiantly rushed into the classroom. However, the wooden door …
They had long disappeared without a trace.
Zhang Feng couldn't bear to look at them directly. He sighed and said, "Alright, don't come in. If you continue to squeeze, the house will burst!"
When the crowd heard this, it was no longer crowded.
Seeing this, Zhang Feng picked up the chalk and wrote two words on the blackboard.
How many!
In an instant.
Everyone looked at these two words and fell into deep thought.
Zhang Feng said slowly, "Everyone, do you know the meaning of these two words?"
Everyone was silent.
Zhang Feng was a little disappointed.
But at this time, Ma Zhou said cautiously, "Teacher, this student seems to have seen this in the textbook before. It seems to be a kind of mathematics?"
In an instant.
Everyone came to a sudden realization.
Zhang Feng looked around and finally nodded with satisfaction.
"Not bad. It seems that you have put some effort into these things."
These words were said to Du Gou, Cheng Chumo, and the others. At this time, the faces of these people turned red. They wanted to retreat, but they couldn't.
Zhang Feng did not pay any attention to them.
After all, if he didn't teach them a lesson, these people definitely wouldn't remember.
At this time, seeing this, Zhang Feng said slowly, "The so-called geometry is actually the accurate data to calculate the size of an object."
"The way we usually know how to measure the data of an object is to use the measurement method and then give it a discount. Although this is a method, sometimes, the accuracy of a matter needs to be calculated many times before the most accurate answer can be obtained."
"For example, building bridges and houses are all places where these things are needed. Today, what I want to teach you is a more accurate calculation method to calculate any part of an object."
"At least, it can save 30 times the time!"
"Hiss —!"
Everyone could not help but suck in a breath of cold air.
Mathematics.
This thing was originally amazing and extraordinary. Since the invention of mathematics, the time to calculate objects was greatly reduced and it was more convenient. Almost now, measuring land and measuring methods were gradually popularized in almost all places.
In other words, the knowledge of mathematics slowly sprouted in the Tang Dynasty.
And more people deeply believed that at this time, only by studying could they change their status and soar to the sky. Those things, as long as they found a master and learned for a few days, they would know the knack of it. Why did they need to study?
And last year, the Imperial College withdrew from the study of mathematics.
But …
There were only two or three people who came to learn. Moreover, these people were forced to come by their families. They were just going through the motions to cover the emperor's face.
Almost everyone knew about this.
At this time, seeing Zhang Feng say so seriously, there was something more awesome than mathematics.
How could this not make all the students not be shocked?
