Windward Fort, inside the discussion hall.

“What is force? Force is the action of an object on an object. For example, I now punch Sir Thorne…”

“What you need to remember is: the effect of forces between objects is mutual!”

“What does it mean?”

“Simply put: as long as an object exerts a force on another object, the object under force will in turn definitely exert a force on the object.”

“That’s why, I punched Sir Thorne, but my fist also hurts, that’s why.”

“You must remember: a pair of interaction forces must be produced and disappear at the same time…”

“There are three major elements of force. They are the magnitude, direction, and point of application of force. They can all affect the effect of force…”

……

After 2 hours.

“The three corners of fire, that is, the three elements of combustion, that is, oxidant, combustibles, and fire source.” Arthur pointed to the three corners of fire pattern on the blackboard: “Only when these three points are present at the same time can combustion occur and continue. Below. , Let’s look at an experiment…”

With that, Arthur lit a small candle standing on the table, and then took the valuable crystal glass and buckled it directly onto the burning candle.

Under the gaze of everyone, the candle’s flame quickly shrank, and after a while, it turned into a black smoke and went out.

“In the last lesson, we said that there are many kinds of gases in the air, and one of them is a combustion accelerator, which is the oxygen we need to breathe!”

“After I buckled the cup, the flame went out because the oxygen in the cup was limited. The combustion quickly consumed the oxygen. Without the oxidizer, the three corners of the fire cannot be established, and the flame goes out.”

“We all know that water can put out fires. So why does water put out fires? I tell you, it’s still three corners of fire!” Arthur knocked on the blackboard standing behind him.

“In the last section, we talked about the changes in the shape of objects. One of them was that water needs to absorb a lot of heat from the surroundings when it evaporates, and this eliminates the element of fire source in the third corner of the fire! The water poured on the flame also cuts off the oxygen in the air and eliminates the element of the combustion-supporting agent in the third corner of the fire. Therefore, water can extinguish the fire.”

……

Another 2 hours later.

“Look at the number axis. Two numbers with different signs are opposite to each other, that is, a and -a are opposite to each other. Note: 2 is neither positive nor negative. The opposite of 0 is still 0. There is no “-0, ＋0″These 0 numbers, 2 is 0…”

“At the 2 end of the number axis, the unit distance is the same, that is, except for zero, 2 numbers with different signs are called mutually opposite numbers. The characteristic is: 2 numbers add up to 0, 2 numbers are equal in absolute value, and 2 numbers are multiplied together. Positive and negative numbers are: -a^2=-(aa)……”

“The opposite of number a is -a, and the opposite of -a is a. Here a is not necessarily a positive number, so -a is not necessarily a negative number…”

……

Every 5 days, the discussion hall of Windward Fort becomes a classroom, and Arthur, the Sir Lord, becomes a teacher incarnation.

It is not the child in the territory who listens to his lectures, but the scholar who serves as a teacher in the school.

At first, Arthur had only ten students. These ten were the Teachers who were in charge of math and science. As the content of his lectures spread among the scholars, the teachers of the school all asked to come and listen to the lectures.

As a result, the object of his class has become all the teachers in the school.

Later, even two senior scholars and the others, Yilu and Boye, joined the student team.

Until now, with the exception of the scholars who withdraw because of work impossible, every five days, most of the scholars in Upper River Collar gather in the discussion hall of Windward Fort to listen to Arthur’s lectures.

After finishing the course, Arthur sat in a chair tiredly.

The lesson in the morning not only exhausted his week of lesson preparation, but also made his calves sore and his throat hoarse.

It wasn’t that Arthur was deliberately showing his abilities and doing nothing to find trouble, but that he really had no other way. No one except himself was qualified for this job.

In the three subjects of history, literature, and geography, he can’t compare to one scholar in ten, but when it comes to mathematics and science, all the scholars of Upper River Collar can’t compare to him alone.

In addition to the introduction of many new concepts, new names, and new symbols, Arthur had to prepare the lessons himself, and went to the battle himself, first taught the Teacher, and then the Teacher went to teach the students.

“Don’t whisper below, have you all taken notes! Hurry up and recall the knowledge points I just mentioned.”

After pouring a large glass of water, Arthur picked up the test paper on the side: “I will ask the class representative to send the test paper to you later. You will try to do it according to what I just said. After half an hour, I will take it back for inspection. “

With that said, Arthur handed the test paper to Leah aside.

Yes, Leah is the class representative.

Since Arthur taught her literacy, Leah’s whole person is like a hack, not only interested in various castle collections, but also full of curiosity and desire to explore the knowledge of mathematics, physics and chemistry proposed by Arthur.

After discovering that Leah has the innate talent in this area, Arthur also intends to train her. When she is free, she will answer all kinds of questions for her.

Leah, who is Arthur’s maid, naturally has more opportunities and time to get Arthur’s advice than scholars. Therefore, in mathematics and physics, Leah is a classmate who is not just in name only, but also in reality!

Looking at the scholars in front of him, Arthur said: “If you don’t understand, don’t understand, ask the Leah class representative. She will answer it for you. If you want to learn knowledge, you should ask without shame! It is still relatively simple knowledge. If you don’t take it The foundation is solid, and it will only be more difficult to listen to the lessons later!”

“Yes, lord!” Scholars respectfully replied.

In the past, scholars respected Arthur only because of his noble identity, but now, it is more out of admiration for his knowledge and humanity!

Arthur had knowledge that they did not understand at all, and imparted it to them selflessly.

Satisfied nodded, Arthur looked towards Leah on the side: “Leah, I’ll leave it to you here, and I will give a good tutor to scholars. Many of them are teachers of the school. Teaching students face-to-face!”

“Yes, Lord Arthur.” Leah agreed with a smile. This is her second time answering questions for scholars.

With a smile, “Uh,” Arthur got up and said, “It’s going to be hard for you, but don’t always stand. When they are doing the test, you will sit in my place and watch them answer the question.”

Leah looked at Arthur with her bright eyes and said, “My lord, I’m not tired at all. You go to rest, you have stood all morning.”

Thorne also said aside: “Sir, let Leah find another chair to sit on.”

“I’m standing just like an adult. I’m really not tired at all. I always sat when you were in class.”

Looking at Leah, who is clever and sensible, Arthur said with a smile: “Just do it, but don’t be too cautious, sit down and rest when you are free, you represent me.”

After Arthur left, Leah began to answer questions for scholars. From time to time she would still hold chalk and draw pictures on the blackboard to explain.

After answering all the questions, Leah posted the question paper written by Arthur, one after another.

When scholars bowed their heads, she stood quietly next to the chair that symbolized the power of the lord.

To be able to share Lord Arthur’s worries, in Leah’s heart, there is a kind of unspeakable happiness…
