Appreciation of "East wind is not convenient for Zhou Lang, and copper finches lock Er Qiao in spring"

Full text:

Red Wall

The iron is not for sale,

Learn from the past.

East wind is not convenient for Zhou Lang,

Bronze sparrow lock Er Qiao Spring.

Precautions:

1, breaking halberd and settling sand: breaking halberd and settling sand; Halberd: A weapon.

2. East wind: Wu Dong attacked Cao Ying in the west, relying on the east wind.

3. Zhou Lang: Zhou Yu, under the command of Wu Jun

4. Er Qiao: Two beauties of Wu, married to Wu; Xiao Qiao married Zhou Yu.

Translation:

The broken halberd sank in the sediment, but it did not melt for 600 years;

I used it for grinding and washing, and I recognized it as Battle of Red Cliffs's.

If Dongfeng did not contribute to Zhou Yu's fire attack plan;

Daqiao Xiaoqiao will be locked in Tongquetai by Cao Cao.

There are many ancient poems about numbers. Take "Pagoda with Lights" as an example:

First of all, pagoda lights.

This is a topic in Nine Chapters Algorithm Analogy written by Jason Wu, a mathematician in Ming Dynasty. The topic is:

Looking at the towering seventh floor from a distance, the red light doubled.

* * * Lights are three hundred and eighty-one. How many lights are there on the top floor?

Solution:

Sum of multiples of each layer:

1+2+4+8+ 16+32+64= 127

Number of lights on the top floor: 38 1÷ 127=3 (lights)

Second, the introduction of the work:

Jiuding acid hair blue boxing, also known as Jiuding blue boxing. Arithmetic in the early Ming Dynasty. The first volume of ten volumes was written by Jason Wu in Ming Dynasty, and it was written in 1450.

The preface of this book is "Examples of Multiplication and Division", which aims to explain the basic theory of the algorithm. This paper lists four operations, such as large number notation, decimal notation, unit of measurement and integer fraction, positioning, square root and difference, and explains them one by one in the form of poetry. The preface also puts forward a "writing algorithm" that has never appeared in China's mathematical works: draw squares according to the number of digits multiplied by two digits. Choose a direction to draw the diagonal of each cell, write the product of every two numbers in the corresponding cell, write it according to the rule that ten digits are above and one digit is below, and then add the diagonal lines one by one to get the digits of the required product. Volumes 1 to 9 are a compilation of solutions to more than 65,438+0,400 application problems, which follow the arithmetic style of nine chapters and belong to "Xiaomi, Decline, Shaoguang Monk". Poetry is expressed in rhyme; The algorithm of the analogy system is similar, combined with the practical application problems at that time, including commodity exchange, partnership management, interest calculation, marking on things (paying fees by commodity pricing) and so on. Volume 10 "Various squares", including square root, square root, high power, and the band from the sum of squares to the cube, uses the method of "standing open" instead of "increasing, multiplying and opening".

Three. About the author:

Jason Wu, whose real name is Xinmin, is a master. Zhejiang Renhe (now Hangzhou) people. Former Minister of State of Zhejiang Shogunate. The date of birth and death is unknown, living in the 15th century 1450 or so. China was a mathematician in Jingtai period of Ming Dynasty. He wrote nine chapters on algorithm comparison.

3. Seeking to Describe Mathematical Poetry China's ancient poetry is an important part of Chinese civilization and a treasure of literature.

In the garden of literature, some poems are sometimes married to mathematics, such as embedding numbers in poems, and some poems are just a math problem. Reading couplets not only improves one's literary accomplishment, but also learns to solve problems and appreciate beauty.

1. Math into poetry, go to Er Sanli. There are four or five smoke villages, six or seven pavilions and eighty or ninety flowers. This is a poem written by Shao Yong in Song Dynasty, which describes the scenery all the way. It has 20 words, and all the numbers 10 are used.

This poem reflects the distance, villages, pavilions, flowers and plants with numbers, which is popular and natural. One, two, three or four, five, six, seven or eight.

Nine dollars, ten dollars, countless dollars, all missing when flying into Mei. This is a poem about Xue Mei written by Lin Hejing in Ming Dynasty. The whole poem uses quantifiers to indicate the number of snowflakes.

After reading it, it's like being in the snow. Snowflakes from less to more, flying into Meilin can't tell whether they are snowflakes or plum blossoms. One nest, two nests, three or four nests, five nests, six nests, seven or eight nests, ate all the royal millet, as few as the phoenix.

This is a poem "Sparrow" by Wang Anshi, a statesman, writer and thinker in the Song Dynasty. Seeing that many officials in the Northern Song Dynasty were full of food, corrupt and opposed to political reform, he compared them to sparrows and satirized them.

One pole, one paddle, one fishing boat, one fisherman, one hook, one leaning on one smile, and one person dominating one river and autumn. This is Ji Xiaolan's "Eleventh" poem in Qing Dynasty.

It is said that Emperor Qianlong saw a fishing boat rowing on the river one day during his southern tour, so he asked Ji Xiaolan to write a poem about fishing and asked him to use ten "ones" in the poem. Ji Xiaolan soon sang a song, wrote the scenery and also wrote the modality, which was natural, decent and full of charm. No wonder Gan Long even said, "What a genius!" Once in Hall 23, there were four or five beds, six or seven smoke lamps and eighty or ninety guns.

In the late Qing dynasty, opium was prevalent, almost no one did not smoke, and the yamen almost became a smoking hall. Someone imitated Shao Yong and wrote this enlightenment poem to satirize it.

In the Western Han Dynasty, Sima Xiangru said goodbye to his wife Zhuo Wenjun, left Chengdu and went to Chang 'an to seek fame. Five years later, instead of writing a letter to his family, he wants to divorce his wife. Later, he wrote a letter to Zhuo Wenjun and sent it to Chengdu.

Zhuo Wenjun received the letter and opened it. It was "1234567891 million, 987654321". She immediately wrote back a lyric poem: after a farewell, the two places hung together, only in March and April, but 1956, the lyre had no intention to dial, and the eight-part essay could not be passed down. The nine-part chain was interrupted, and I saw through the ten-mile pavilion, and I was full of thoughts, so I had no choice but to call it a maid.

I'm tired of complaining about lang. I see the lonely geese in Chongyang in 1999, and the Mid-Autumn Festival in August is not round. In July and a half, I burned incense and lit candles to worship my ancestors. In the dog days of June, everyone shakes my heart. In May, pomegranates are like fire, and the flowers fall after the rain. April loquat is not yellow, I am lazy. Peach blossoms are blown away by the wind in March! Lang Lang, I wish you were a woman. I am a man in the second century. Sima Xiangru was deeply moved after reading, and personally went back to Sichuan to pick up Zhuo Wenjun from Chang 'an.

From then on, he devoted himself to study and finally became a generation of writers. 2. Interesting topic of poetry 1. Mathematics is an abstract thinking activity, which has nothing to do with poetry. But Xu Ziyun, a poet in Qing Dynasty, combined "abstraction" with "image" to create this mathematical poem: the majestic ancient temple is in the mountains, and I don't know how many monks there are.

364 bowls, depending on the week. Three people eat a bowl of rice and four people eat a bowl of soup.

Excuse me, sir, how many monks are there in the temple? There are 364 bowls in the temple. If three monks eat a bowl of rice and four monks eat a bowl of soup, then each monk will have something to eat. How many monks are there in the temple? "Every week is not bad" means it is very accurate, and that's the way to count later. It's not bad at all. Obviously, this algebra problem can be solved by junior high school students with a little brain-let the number of monks be x and list the following algebraic expressions: x/3+x/4=364, x=624. 2. The Hundred Sheep Problem was written by Cheng Dawei, a great mathematician in the Ming Dynasty. There is a mathematical application problem in the form of poetry called the Hundred Sheep Problem.

A drives a sheep to chase grass, B pulls a sheep, and then asks A and 100? Jia Yun said there is no difference, so a group of people get together and add a small group, so you have to get together. Who can guess the mystery? A shepherd is driving a flock of sheep to find a place with lush grass. A man with a sheep came from behind and asked the shepherd, "Do you have 100 sheep?" The shepherd said, "If I have another flock of such sheep, plus half of this flock and 65,438+0/4 flock of sheep, plus your sheep, it will be exactly 65,438+000.

"Who can use clever methods to find out how many sheep there are in this group? The solution of this problem is: (100-1) ÷ (1+1+1/4) = 36. 3. Li Bai walks on Li Bai Street, making wine with a pot; When you meet a store, double it, see flowers and drink a bucket; I met the shop flower three times and drank all the wine in the pot. How much wine is there in the hip flask? This is a folk arithmetic problem.

The title means: Li Bai is walking in the street, drinking and carrying a hip flask. Every time he meets a hotel, he doubles the wine in the kettle. Every time he meets flowers, he drinks a barrel (barrel is an ancient unit of capacity, 1 barrel = 10 liter), so he meets flowers three times in the store and drinks the wine. How much wine is there in the pot? The problem was solved by equation.

There used to be a barrel of wine in the pot. Get [(2x-1) * 2-1] * 2-1= 0, get x=7/8.

4. There is such a problem in the "Arithmetic Unity" written by Cheng Dawei, a great mathematician in the Ming Dynasty: one hundred steamed buns and one hundred monks, but three big monks have not increased; One of the three young monks, and how many big and small monks? This problem can be solved by hypothesis. Now suppose there are 100 big monks, (3 *100) ÷ (3-13) = 75 (people). The number of small monks in ........................................................ is100.

Who can count? How much meat is there today? The meaning of this question is expressed by a line graph, which is clear at a glance. As can be seen from the figure, the price of every two pieces of meat is: (40+ 16)÷( 16-9)=8 (text): 8* 16-40=88 (text): the dumb can buy meat.

4. Poems about Mathematics The majestic ancient temple is in the mountains. I wonder how many monks there are in the temple. There are 364 bowls. Let's see how many monks there are in the temple. Three people eat a bowl of rice and four people eat a bowl of soup. Excuse me, sir, how many monks are there in the temple? There are 364 bowls in the temple. If three monks eat a bowl of rice and four monks eat a bowl of soup, then each monk will have something to eat. How many monks are there in the temple? "Every week is not bad" means very accurate, and the figures are not bad at all. Obviously, this algebra problem can be solved by junior high school students with a little brain-let the number of monks be x and list the following algebraic expressions: x/3+x/4=364, x=624.2. Cheng Dawei, a great mathematician in Ming Dynasty, wrote the book "Algorithm Unification". Jia Yun said there is no difference, so a group of people get together and add a small group, so you have to get together. Who can guess the mystery? A shepherd is driving a flock of sheep to find a place with lush grass. A man with a sheep came from behind and asked the shepherd, "Do you have 100 sheep?" The shepherd said, "If I have another flock of such sheep, plus half of this flock and 65,438+0/4 flock of sheep, plus your sheep, it will be exactly 65,438+000." Who can find out how many sheep are in this flock by clever methods? The solution of this problem is: (100-1) ÷ (1+1+1/4) = 36. 3. Li Bai walks on Li Bai Street, making wine with a pot; When you meet a store, double it, see flowers and drink a bucket; I met shops and flowers three times and drank all the wine in the kettle. How much wine is there in the kettle? This is a folk math problem. The meaning of the question is: Li Bai is walking in the street, drinking with a hip flask. Every time he meets a hotel, the capacity in the hip flask doubles, and every time he meets flowers, he drinks a barrel (barrel is an ancient unit of capacity, 1 barrel = 10 liter). In this way, he met the flowers three times in the shop and finished the wine. How much wine is there in the hip flask? The problem was solved by equation. There used to be x barrels of wine in the pot. We get [(2x-1) * 2-1] * 2-1= 0, and the solution is x=7/8.4. Cheng Dawei, a great mathematician in the Ming Dynasty, has such a problem in "Arithmetic Unity". One of the three young monks, and how many big and small monks? This problem can be solved by hypothetical method. Now suppose there are 100 big monks, (3 *100-100) ÷ (3-13) = 75 (people) .....................................................................
