Shen Wenjun led everyone from Xiaoxiang Academy out of Linjiang Pavilion and came to the backlight.
It was almost noon here, and the sun was shining in the sky, casting the shadow of Linjiang Pavilion on the square.
The floor tiles in the square are three feet long, and the shadow covers exactly sixty-three floor tiles, so the shadow is about twenty feet long.
Then, she took a bamboo pole about ten feet long as a reference object and stood it under the Linjiang Pavilion. The shadow of the bamboo pole was calculated to be one foot long.
According to the law of the sun, at the same time, the higher an object is, the longer its shadow will be. These two quantities are related quantities, and as one quantity becomes larger, the weight of the other will also become larger, forming an equal proportion;
If the height of the bamboo pole is compared with the height of the bamboo shadow, it is equal to the height of Linjiang Pavilion compared with the height of Linjiang Pavilion's shadow. After conversion, the shadow is one and a half times the size of the real thing. Then the shadow of Linjiang Pavilion is twenty feet long, and the height is It is thirteen feet per foot.
"Master Liu, through conversion, I found that the Linjiang Pavilion is 13 feet high. There may be a deviation of half a foot. Are you right?" Shen Wenjun asked.
Liu Boyong exclaimed: "I personally supervised the renovation of this Linjiang Pavilion. It is indeed thirteen feet tall. Including the golden tripod in the attic, it is exactly one foot more. Mrs. Song is really amazing."
Shen Wenjun looked arrogantly at Cao Guojin, who had a gloomy face, "Dean Cao, this second round, Xiaoxiang Academy has taken the next step."
Cao Guojin only whispered: "Please come up with a question."
"Since your academy has a difficult problem of measuring height, I will give you one as well." Shen Wenjun placed a finger on the flagpole in the square and made a gesture to Ning Yehong beside him.
Ning Yehong walked to the flagpole, jumped up and cut the flagpole in half with a knife, and used a ruler to measure the length of the flagpole: "This section is 1.3 feet long."
"Dean Cao, we know that the height of the flagpole when it is stuck on the ground is one foot and three feet, so how high is the total height of the flagpole? You can find reference objects, but you are not allowed to measure the broken pole. Please solve the problem." Shen Wenjun asked for instructions, He waved again, lit half a stick of incense and started counting.
Cao Guojin brought a few students to the flagpole and looked around the broken pole again and again. The incense burned little by little, but they had no clue.
Seeing that the time was approaching, Zeng Hou became anxious again, "Where have you learned the calculations and chapter numbers in your daily life? Hurry up and solve the problems!"
His urging undoubtedly increased the psychological burden on Cao Guojin and others, and sweat began to break out on their heads.
"Teacher, this is simply an unsolvable problem. The broken pole is so random, who knows its length?" Cao Guojin glared at Shen Wenjun: "You are eager to win, so there is no need to create an unsolvable problem to make things difficult for us!"
Shen Wenjun didn't bother to mock them. He just tilted his head and said to Qin Ruo from the side: "He must not have hooked his wife's ass."
Qin Ruo covered her mouth and snickered, "That's right, that's right..."
"Half of the incense burnt out, the time has come. This second competition...well, Xiaoxiang Academy won." Liu Boyong pointed at the burned out incense burner and announced loudly.
"Wait a minute!" Cao Guojin stopped, "The prerequisite for victory is that the problem can be solved. If he deliberately asks an unsolvable problem, we will not be convinced at all!"
"Okay, then I'll make you convinced that you lost!"
Qin Ruo walked to the flagpole, picked up the broken half, put it on the port, and arranged it into a right triangle. She said: "We know that the height of the vertical pole is one foot and three, and then visually inspect the shadow of the vertical pole to be one foot and eight." , calculated by hooking three strands and four xuanwu, the length of the broken pole is about two feet. If you add the broken pole to the vertical pole, then the original height of the flagpole is three feet. It may be less than half a foot. If you don’t believe it, Mr. Liu You can measure it yourself.”
Liu Boyong took a ruler and compared it foot by foot in front of everyone. After measuring, the length of the flagpole was indeed three feet and a half feet.
All the scholars in Lingyin Academy were speechless again.
"Hmph, don't be complacent. Riding, shooting, and arithmetic are, in our academy's opinion, nothing more than supplementary courses for cultivating one's sentiments. What the academy really teaches is literature. In the third poetry competition, I will personally compete with you. I want you to be convinced!"
Everyone returned to Linjiang Pavilion and sat down again.
"Liu Sheng, please come up with a topic quickly. I'm currently in the mood for poetry!" Zeng Hou urged.
Liu Boyong pointed to the inscription in front of the pavilion and said with a smile: "The famous line in the "Preface to Linjiang Pavilion" in the previous article, 'Be worried about the world's worries first, and be happy after the world's happiness', made Linjiang Pavilion in Hangzhou famous all over the world. Today, all Confucian scholars Scholars and talents gather together again, why not write a famous poem with the theme of climbing high and hang it in the hall, so that the name of Linjiang Pavilion can be raised to a higher level?"
"Okay!" Zeng Hou walked out of his seat, "Fortunately, "Preface to Linjiang Pavilion" is prose, otherwise I would not dare to write ink in front of this famous article, so I will write a poem and give it to this pavilion!"
As soon as these words came out, all the scholars sat upright and listened attentively.
Seeing Zeng Hou coming to the fence, he looked at the sea for a moment and chanted:
"The Canghai Tower shines brightly on the blue clouds, and the white sand falls on the Qianjiang River pond. The sound of the waves slowly stops the passenger ship, and the willows are green and red. I scratch my head and ask the sky, and I meet the Hakka with a pot of wine. The sun is a long rainbow for thousands of miles, and the green clouds hang down half a pot. yarn."
"good!"
"As expected of Mr. Zeng, his words are famous poems throughout the ages!"
"Quick! Record the teacher's writings quickly. I want to engrave them on the beams and pillars for the world's literati to appreciate!"
Not to mention them, even Nangong Yue and Liu Xinnan couldn't help but admire the good poem.
"Don't be silent. Aren't you talented women? It's your turn to write poetry." The scholars in Lingyin Academy seized this opportunity to avenge their shame and kept urging and mocking Nangong Yue and Liu Xinnan.
Liu Xinnan gritted her teeth and looked at Nangong Yue: "Do you have any good poems?"
Nangong Yue was extremely unsure, "Yes, yes, but...but...oh..." She could only turn her head to ask Song Che for help.
Song Che frowned and thought to himself: This old guy really has some skills. Even if he can find Tang poetry to compete with him, he will at most be tied with him. If he wants to surpass him in attainments, he must be unprecedented. Only the famous article of the visitor will do.
"Let's do this..." Song Che leaned close to Nangong Yue's ear and whispered twice.
Nangong Yue sighed and nodded, stood up and said to Liu Boyong: "Master Liu, Mr. Zeng took the lead with his "Spring View" and enjoyed all the beautiful scenery of Linjiang Pavilion during the day. Even if I can write good poems about scenery, It is also difficult to surpass, so I want to write poetry after dark, so that a day, a night, a sun, and a bright moon can create a better contrast."
"If you can't compare, you can't compare. What's the difference between day and night? I see, they are obviously stalling for time to come up with good poems to respond! We, Mr. Zeng, improvised!"
"Looking at the whole Jiangnan, who can compare with Mr. Zeng's poems? In my opinion, you should give up early!"
"No!"
Zeng Hou raised his hand and spoke, "She is right. The bright sun in the sky and the bright moon in the night are an excellent contrast. I only write poems during the day, and she should write poems about the night. It doesn't matter if she waits!"
