The emperor's son descended to Beizhu, his eyes were dim and he was sad, the autumn wind was blowing in the cave, and the leaves were falling... ——"Mrs. Hunan"·Qu Yuan It is also interesting to look at these two poems through geometric mechanics. The surging "waves" are upward, the withered "wooden leaves" are downward, and the "autumn wind" is advancing from north to south on the plane of the earth - forces in three directions. When combined in a poem, they promote the movement of the seasons and the pulse of our poetic life in another way.
Poetry and Physics Teaching Yuzhong County No. 1 Middle School Ding Cheng China is a kingdom of poetry. Poetry not only brings artistic enjoyment to people, but also contains certain physical knowledge in some works.
Using this precious wealth and inserting poetry into physics teaching will definitely be the icing on the cake. 1. Using poetry to introduce physical concepts can make students more interested and active.
For example, when talking about some concepts of the movement of objects, we can use the verses from Chairman Mao's poem "Sending the God of Plague": "Sit on the ground and travel eighty thousand miles a day, survey the sky and see a thousand rivers in the distance." From this Introducing the concept of motion as an absolute, the earth beneath our feet is constantly in motion.
Chen Yuyi, a poet of the Song Dynasty, wrote in a poem called "Xiangyi Daozhong": "The 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. I lie down and look at the clouds in the sky without moving, and I don't know the clouds. Stay with me."
From the last two poems, 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.
Another example is Tao Yuanming's "The sun sinks down the West River, and the plain moon rises out of 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 will listen with interest, the classroom atmosphere will be active, and the effect will be 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: "Only relying on the power of the wind can make the kite fly." , It’s true that the feathers are abundant. The red line flies into the sky, and the blue clouds have a path."
And the force analysis was done, and the effect was excellent. Another example is when teaching the law of linear propagation of light and the formation of shadows, using the Song Dynasty poet Su Shi's "Flower Shadow" will help students understand: "There are many layers on the Yaotai, and the children can't sweep them away after repeated calls.
Just after being swept away by the sun, the bright moon is sent to the future." Another example, when talking about the dispersion of colors, we can use Mao Zedong's poem "Bodhisattva Barbarian Dabai Di": "Red, orange, yellow, green, blue, blue, purple, who holds the color and practices it in the sky." Dance.
The sun sets after the rain, and the mountains are green. 3. Use physics knowledge to appreciate Chinese poetry, so that students can learn something useful.
After learning about the reflection of light, The word "frost on the ground" in Li Bai's poem "The moonlight shines in front of the window, it is suspected to be frost on the ground" will give you a more profound understanding. Another example is Li Bai's "Wanglu Mountain Waterfall": "The sun shines on the incense burner and produces purple smoke, and the waterfall hangs in front of the river." .
The flying stream falls three thousand feet, and it is suspected that the Milky Way has fallen into the sky. "The majestic waterfall turned into the Milky Way falling into the sky in the eyes of the poet.
Without knowledge of optics, I am afraid that the understanding of these two poems will not be too deep. Another example is through studying physics, the students Knowing some concepts of time and space, let’s review Li Bai’s “Early Departure from Baidi City”: “The White Emperor bids farewell to the colorful clouds, and thousands of miles of rivers and mountains are returned in one day.
The apes on both sides of the bank can't stop crying, and the boat has passed the Ten Thousand Mountains. " This poem talks about the movement of people and boats in space.
From the 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 the location changes, 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. This kind of spatial movement is not accompanied by "one day". 4. Use physical knowledge to identify Chinese poetry, so that Hesitation can view the problem dialectically. After studying the chapter of "Physical Changes", insert Zhang Ji's popular "Mooring on the Maple Bridge": "Moonset". The sky is filled with black tellurium frost, and the river maple and fishing fire are facing melancholy.
At 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 in the sky. How can it be said that "the sky is full of 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. Moreover, we cannot ask the ancients to use today's scientific knowledge to write poetry.
However, physics. If 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 students' interests, strengthen physics concepts, and improve teaching effectiveness. Reading this article, I don’t know if it will be useful to you.
8. Ancient poems about science
"Peach Blossoms in Dalin Temple"
——Bai Juyi, Tang Dynasty
When the beauty of April in the world is gone, the peach blossoms in the mountain temple begin to bloom. < /p>
The eternal regret that spring returns is nowhere to be found, and I don’t know where to turn.
Scientific knowledge: The temperature in the mountains is lower than that on the ground, so spring comes later.
"Miscellaneous Poems of Ji Hai"
——Gong Zizhen of the Qing Dynasty
The sun is setting in the day when I am sad about the great separation, and I chant my whip and point to the east to reach the end of the world.
Falling Red is not a heartless thing, it turns into spring mud to protect flowers.
Scientific knowledge: Adding humus from plants to the soil can make the soil fertile.
"Climbing the Stork Tower"
——Wang Zhihuan of the Tang Dynasty
The sun sets over the mountains and the Yellow River flows into the sea.
If you want to see a thousand miles away, go to the next level.
Scientific knowledge: Stand high and see far.
"Farewell with ancient grass"
——Bai Juyi of the Tang Dynasty
Leaving the original grass on the grass, One year old and another withering glory.
The wildfire cannot be burned out, but the spring breeze blows and grows again.
The distant fragrance invades the ancient road, and the clear green meets the deserted city.
Send the king off again The sun is gone, and the love is full of love.
Scientific knowledge: The vitality of weeds is very tenacious. 9. Poems, proverbs, or idioms related to physical knowledge
1. Little nicknames A weight weighs a thousand pounds - According to the principle of lever balance, if the power arm is a fraction of the resistance arm, the power is several times the resistance. If the force arm of the weight is very large, then it is entirely possible to "lift a thousand pounds with one or two strokes".
2. A broken mirror cannot be reunited - when the distance between molecules is large (greater than a few hundred angstroms) , the gravitational force between molecules is very small, almost zero, so it is difficult to reunite a broken mirror.
3. What cannot be picked is the moon in the mirror. What cannot be picked is the flower in the water - the image formed by a flat mirror is a virtual image.
4. When people unite, Mount Tai will move - If the directions of each component force are the same, then the resultant force is equal to the sum of the magnitudes of each component force.
5. Lifting tofu with hemp rope - it cannot be lifted - when the pressure is constant, if the force-bearing area is small, the pressure will be large. Supplementary answer 6. Real gold is not afraid of fire, and truth is not afraid of debate. From the perspective of the melting point of gold, although it is not the highest, it is still 1068°C, and the temperature of the general flame is about 800°C. Since the temperature of the flame is smaller than that of gold, melting point, so gold cannot melt.
7. The moon is haloed by wind, and moist by rain - when strong winds come, the temperature in the sky drops rapidly, and water vapor condenses into small water droplets. These small water droplets are equivalent to many prisms, and the moonlight passes through these "prisms" "Dispersion occurs and a colorful moon halo is formed, so there is a saying that "the moon halo causes wind".
Base moisture refers to the reverse moisture on the ground. Before a heavy rain comes, the air humidity is high and the ground temperature is low. The water vapor near the ground condenses into small water droplets when condensed. In addition, the salt contained in the ground easily absorbs moisture. Water vapor, so the reverse tide on the ground indicates that heavy rain is coming.
8. When a person roars loudly in the mountains, the valley echoes. The sound can form a loud echo through multiple reflections. It lasts for a long time, as if the mountains are roaring and the valleys are roaring. In echo.
