Poems about mechanics

The emperor's son descends to Beizhu

My eyes are dim and melancholy

The autumn wind is blowing

The ripples of the trees in Dongting are falling

——"Mrs. Xiang"·Qu Yuan

It is also quite interesting to look at these two poems through geometric mechanics. The surging "waves" move upward. , the withered "wooden leaves" move downward, while the "autumn wind" advances from north to south on the plane of the earth - when the forces of the three directions are combined in a poem, they promote the movement of the seasons in another way , and the pulse of our poetic life.

Poetry and Physics Teaching

Ding Cheng, No. 1 Middle School in Yuzhong County

China is a kingdom of poetry. Poetry not only brings artistic enjoyment to people, but also contains certain physical knowledge in some works. Utilizing this precious wealth and inserting poetry into physics teaching will surely be the icing on the cake.

1. Using poetry to introduce physics concepts can arouse students' interest and make the atmosphere active.

For example, when talking about some concepts of the movement of objects, we can use the verses from Chairman Mao's poem "Send the God of Plague":

"Sit on the ground and travel eighty thousand miles in a day,"

Survey the sky and see a thousand rivers in the distance.”

This introduces the concept that motion is absolute, and the earth under our feet is always moving. Chen Yuyi, a poet of the Song Dynasty, wrote in a poem called "Xiangyi Daozhong":

"Flying flowers shine in the evening red on both sides of the bank, and the wind blows half a day on the hundred-mile elm embankment.

Lying down and watching the clouds in the sky remain motionless,

I don’t know whether the clouds are east of me or not.”

From the last two lines of the poem, we can introduce the concept of stillness as a relative concept. Here, the ship and the cloud move at the same speed. Using the ship as a reference, the cloud is stationary.

For example, Tao Yuanming's "The sun sinks to the west river, and the plain moon rises from the east ridge", and Li Bai's "The lonely sail is far away and the blue sky is gone, but only the Yangtze River skyline is seen" can introduce some concepts of movement.

These poems are vivid, vivid and interesting. By introducing physics concepts in this way, students listen with interest, the classroom atmosphere is active, and the effect is to get twice the result with half the effort.

2. Using poetry to understand physical concepts can make students think fluently and make a deep impression.

When understanding the interaction between special bodies and the decomposition of forces, and analyzing the reasons why kites can float in the air, you can read "The Kite" by Wu Youshui in the Qing Dynasty to students:

< p>"Just relying on the strength of the wind,

doesn't mean you have abundant feathers.

The red line flies through the sky,

There is a road to the blue clouds."

The force analysis was also done, and the effect was excellent.

Another example is when teaching the law of linear propagation of light and the formation of shadows, using "Flower Shadow" by the Song Dynasty poet Su Shi can help students understand:

"Lay over and over again." Yaotai,

I couldn’t sweep it away

It was just swept away by the sun,

and the bright moon sent me to the future. ”

< p>Another example, when talking about dispersion, we can use Mao Zedong's poem "Bodhisattva Barbarian Dabai Di":

"Red, orange, yellow, green, blue, blue, purple,

Who holds the color and practices dancing in the air .

The sun returns after the rain,

Guanshan is green.

3. Use physics knowledge to appreciate Chinese poetry and make it useful.

After learning about the reflection of light, you will have a deeper understanding of the word "frost on the ground" in Li Bai's poem "The bright moonlight in front of the window is suspected to be frost on the ground"

Another example. Li Bai's "Wang Lushan Waterfall":

"The sun shines on the incense burner and produces purple smoke.

Looking at the waterfall hanging in front of the river in the distance.

The flying current flows down three thousand feet,

It is suspected that the Milky Way has fallen into the sky. "

In the poet's eyes, the majestic waterfall turned into the Milky Way falling into the sky. If there is no knowledge of optics, the understanding of these two poems may not be too deep.

More For example, through studying physics, students know some concepts of time and space. Let's review Li Bai's "Early Departure from Baidi City":

"Chaoci Baidi's colorful clouds,

Thousands of miles away" Jiangling will be returned in one day.

The apes on both sides of the strait can’t stop crying.

The boat has passed the Ten Thousand Mountains. ”

This poem talks about the movement of people and boats in space. From Baidi in the west to Jiangling in the east, it flows down the river for thousands of miles. Amidst the bursts of ape calls, as the boat moves, Everywhere you look, you can see mountains and valleys in various shapes, which makes people feel relaxed and fascinated. I leave Baidi in the morning and arrive in Jiangling in the evening. Isn’t this kind of spatial movement accompanied by the change of time in a day?

4. Use physical knowledge to identify Chinese poetry, so that Hesitation can look at problems dialectically.

After studying the chapter "Changes in the State of Matter", insert Zhang Ji's popular "Maple Bridge". "Night Mooring":

"The moon sets and the sky is covered with black tellurium frost.

Jiang Feng fishes with fire to worry about sleep.

Hanshan Temple outside Gusu City,

The midnight bell rang for the passenger ship. ”

Through careful analysis, we can see that there are indeed mistakes in this poem. According to physical knowledge, when the dew point drops below zero, the water vapor on the earth’s surface condenses and forms frost. It can be seen that frost It is formed on the ground, and it has never been to the sky. How can it be said that "the sky is covered with frost"? Apparently the poet Zhang Ji believed that frost, like snow, fell from the sky, which violated the laws of nature.

Of course, literature is not physics after all. It allows the use of imagination and synaesthesia techniques. Moreover, we cannot ask the ancients to use today's scientific knowledge to write poetry. However, if physics teachers can guide students at any time to use the physics knowledge they have learned to appreciate and identify the works of their predecessors, it will be of great benefit to stimulate students' curiosity, cultivate a wide range of student interests, strengthen physics concepts, and improve teaching effectiveness. of.
