Chapter 210 This question is too difficult...

Previous page        Return to Catalog        Next page

    "Master, please tell me the correct answer"

    Wang Dingjue knelt in front of Zhao Hao. Looking at his disheveled hair and bloodshot eyes, it was no wonder that his brother thought he was crazy.

    Wang Xijue quickly reminded in a low voice: "Brother, when it comes to talking about it, you are peers"

    "Go away, I don't have a brother like you." Wang Dingjue has suffered inhuman torture in the past two days. He was stabbed with needles by witches, poured incense and ash water into his mouth by an old Taoist, and whipped by a godly man. His whole body was humiliated.  I'm going to die.

    ¡°And this humiliation actually came from his dearest eldest brother, which was even more unacceptable to Wang Dingjue.  He glared at Wang Xijue with burning eyes and said:

    "Wang Xijue, I will never forgive you in this life!"

    "This, this" Wang Xijue made his brother blush, and rubbed his hands in embarrassment: "If you look like this, anyone else would think you are crazy."

    "Where am I crazy? Didn't I tell you that I am fine and sober? Have I never understood this before?" Wang Dingjue asked angrily.

    "No madman admits that he is mad" Wang Xijue muttered in a low voice. He was a bit naive and didn't know how to coax his brother to talk at this time.

    Naturally, Wang Dingjue became more and more angry.  His eyes were as red as a bullfight, and he was about to jump up and fight him desperately.

    Zhao Hao originally had the mentality of watching a show. After all, Wang Xijue's funny drama was an important pastime for the people during the Longwan Dynasty.

    Now the protagonist is giving a wonderful performance right in front of you. This opportunity cannot be missed.

    However, seeing the signs that the comedy drama was developing into an ethical tragedy, he had no choice but to say to Wang Xijue: "Bring the book."

    These words were easier to use than red cloth. Wang Dingjue immediately diverted his attention and looked at Zhao Hao with excitement.

    "What book?" Wang Xijue was stunned, then patted his head and said, "Oh, you said that demon book"

    Before he finished speaking, he saw Wang Dingjue and Er Yang showing murderous looks, so he had to quickly change his words: "Geometry is the first glimpse, geometry is the first glimpse."

    "You won't destroy it, right?" Zhao Hao asked.  Usually in such large-scale rituals, there is a step to burn unclean things.

    "No, I just burned the ghost talismans he wrote. The book is still intact." Wang Dingjue called to the housekeeper and brought a wooden box covered with talismans.

    "Uncle Shi is really willing to spend money." Hua Shuyang couldn't help laughing when he saw this. He knew that those talismans were said to contain magic power, and the money was calculated per piece.

    "Oh, no matter how much money it is, isn't it all to help him recover as soon as possible, don't delay and try it?" Wang Xijue glanced at his younger brother helplessly, looking like a parent who didn't understand him.  In fact, if spring wasn't around the corner, he wouldn't be so nervous.

    Wang Dingjue only tilted his head and hummed.

    ??~~

    Wang Xijue tore open the talisman, took out the key, and took out a sealed wooden box from inside.

    Zhao Hao and others could see clearly that the seal said ¡®Om, Mah, Ne, Ba, Mi, Hum¡¯. They couldn¡¯t help but twitch the corners of their mouths. This old Wang was still practicing Confucianism, Taoism and Buddhism.

    "Isn't this just a matter of seeking medical attention in a hurry? I'm thinking of asking a few more doctors, it will always work."

    Wang Xijue awkwardly opened the seal and took out the sealed book "A Preliminary Look at Geometry".

    As soon as Wang Dingjue saw the book "A First Look at Geometry", he immediately became energetic.  He jumped up from the ground like a civet cat, held the book in his hand, then jumped back to kneel down in front of Zhao Hao, turned to one of the pages, raised it high above his head and said:

    "Teacher, this question is too difficult, I can't do it!"

    Zhao Hao took the book and looked at it, and saw that it was Proposition 11 of the second volume.  The original question is "A known line segment can be cut so that the area of ??the rectangle formed by it and a small line segment is equal to the area of ??the square with the remaining line segments as sides."

    Of course, in order to conform to the habits of scholar-bureaucrats, Zhao Hao specially modified the classical Chinese language and replaced the letters with twelve heavenly stems such as ¡®A, B, C, and D¡¯.

    Zhao Hao smiled slightly and couldn't help but praise: "It's hard to see this. It can be said to be very rare."

    ??This is said sincerely.

    "Students are stupid, and there are many questions in front of them that I don't understand, but this question fascinates me the most." Wang Dingjue said with a confused look on his face:

    "I always feel that this dividing point is mysterious and mysterious, and I fell into it without knowing it."

    "Yes, this point is the so-called golden section point." Zhao Hao laughed and said to his apprentice: "Which one of you can deduce it for him?"

    Wang Wuyang immediately raised his hand first.

    Hua Shuyang was a step too slow, so he had to retract his hand in frustration and help his senior brother lay the ground.He took out the paper, and took out a ruler and pencil from his treasure bag

    Because the brush cannot be used to draw with rulers and compasses, Zhao Hao had long wanted to invent the pencil.  But the students understood what he meant and did not dare to remind the teacher directly. Instead, they bought a box and placed it quietly on his desk.  Only then did Zhao Hao know that pencils already existed in Ming Dynasty.

    Wang Wuyang told him that this thing is called "lead coffin", which is made of graphite powder and rolled strips with glue. It can be used directly for writing.  In the scriptures handed down from the Tang and Song dynasties, a common boundary called "Wu Silan" was drawn with a pencil.

    ¡°It¡¯s just because it¡¯s not commonly used and Zhao Hao didn¡¯t pay attention to it, so he made an mistake.

    Seeing that Master also didn¡¯t understand things, Eryang not only didn¡¯t feel disillusioned, but instead felt closer to Master.

    After all, an all-knowing saint can only be worshiped. Only a flesh-and-blood person who can be confused can make people feel close to him.

    ??~~

    "This question is actually not difficult, but it needs to be proved based on the sixth proposition of this chapter"

    Wang Wuyang explained it while making pictures, and Wang Dingjue made everything clear and clear.

    Even Wang Xijue, who was watching carefully from the side, looked surprised.

    After all, the beauty and pleasure contained in the ingenious and rigorous derivation process is, to a certain extent, no less than reciting an heroic article or reciting a famous poem.

    When Wang Wuyang finished explaining, Hua Shuyang, who couldn't hold himself back, grabbed the pen and ruler again, and then showed off:

    "Actually, this point can also be found using the Pythagorean technique of our ancestors. If you don't believe it, look, we assume that the length of the strand of a right triangle is twice the length of its hook, then the sum of the hook strings of this triangle is equal to the sum of the hook strings  Add the difference to the strands, and the sum of the hook strings is divided into golden parts by the difference between the hook strings and the strands. The problem is solved. Master, am I doing this right?"

    "Oh" Wang Dingjue suddenly realized it and said excitedly: "Let me just say this is mysterious, right? It turns out that it seems to have a different origin from Pythagorean, but it is still in the Pythagorean state!"

    In fact, Zhao Hao also wanted to say "Oh", because this was the first time he had heard of this solution outside of the textbook.

    But considering his dignity as a teacher, he could only pretend to be profound and nodded slightly, saying that Hua Shuyang did a good job and was right.

    ???????????????????????????????????????? There is no way, being a teacher to a genius disciple is so boring, guilty, and easy to hurt your self-esteem

    "Now you understand? Why did the tutor only give propositions but not the derivation process? He was afraid of restricting our thinking." Seeing Zhao Hao nodding, Hua Shuyang's excited little face flushed, and he shouted excitedly: "Family  The teacher is asking us to break away from the rules and learn to think independently!"

    Zhao Hao could only continue to nod. In fact, he just deliberately dug a hole for others to jump in

    "Yes, this is all the hard work of the tutor!" Wang Wuyang also nodded heavily: "This is the spirit of science, the quality that a tutor must possess!"
