"The fragrance of flowers suddenly warms people's hearts, and the magpies are happy to wear trees." This is a poem written by Lu You, a poet in the Southern Song Dynasty, in Happy Village, which describes the beautiful scenery of a mountain village with beautiful spring scenery and flowers. From a physical point of view, the previous sentence can be understood as: the diffusion of aromatic oil molecules secreted by flowers accelerated, indicating that the surrounding temperature suddenly rose at that time. "Hanshan Temple outside Gusu City, going to a passenger ship at midnight" in the Tang poem a night-mooring near maple bridge. People on passenger ships near Qiao Feng heard the bells of Hanshan Temple, because the bell of Hanshan Temple was hit by a monk and shook. People on the passenger ship can tell that the sound is "bell" instead of "drum" or other sounds. In fact, he can judge by the timbre of his voice. In Li Daoyuan's Three Gorges, there is a description of "the empty valley echoes, and the sorrow and joy turn away for a long time". The reason for this phenomenon is that the echo disappears after hearing obstacles in the process of sound propagation. "The trees grow dark in summer, and the balcony reflects the pond" is a poem written by Gao Pian, a poet in the late Tang Dynasty, which describes the unique taste of cool summer and expresses the poet's happy mood. From the physical point of view, the formation of "shadow" in the poem shows that light travels along a straight line; "Balcony reflection" is a reflection phenomenon of light, and the image is an upright virtual image. "How wide the world is, how close the trees are to heaven, and how close the moon is to the water!" It is a poem in "Sleeping at Jiande River" by Meng Haoran, a poet in the Tang Dynasty, which expresses the loneliness and desolation of living in a foreign country. However, from a physical point of view, the phrase "How close the moon is in the water!" It is not scientific, because according to the imaging law of plane mirror, the moon shadow in water and its appearance in the sky are symmetrical to the water surface, so the moon and the moon shadow are symmetrical at any point on the water surface. Until, holding up my cup, I asked the bright moon to bring me my shadow and let the three of us. The last sentence of "Drinking the Bright Moon Alone" by Li Bai (Tang) mainly explains the phenomenon that the moon is imaged in a wine glass, which involves the reflection of light. According to the meaning of the poem, the last sentence can be understood from a physical point of view as: people, the shadow under the moon, the people in the glass become three people.
2. Ancient poems and proverbs about physics 12 sentence: the refraction and reflection of light between the colorful clouds of Baidi.
Jiangling, thousands of miles away, the relationship between distance and time.
Apes on both sides of the strait can't stop crying, and their voices are generated and spread.
The canoe has passed through Chung Shan Man, and the change of object position is called mechanical movement.
First, the energy knowledge in ancient poetry
1. Su Shi's poem "Bow like a full moon, look northwest, shoot Sirius". The energy conversion involved in poetry is the conversion from elastic potential energy to kinetic energy.
2. Li Bai's poem "Flying down three thousands of feet, it is suspected that the Milky Way has set for nine days". Waterfalls in poetry contain great mechanical energy.
Second, the reference knowledge in ancient poetry.
1, Mao Zedong's poem "Sit on the ground and walk 80,000 miles a day, overlook the sky and see John Wan" means that "sit on the ground" is static relative to the ground, and "walk on the sky" is moving relative to the sun.
2. Li Bai wrote in the poem "Looking at Tianmen Mountain" that "the green hills on both sides of the strait look at each other and sail alone." "Castle Peak Opposite" is set in a boat, and "Lonely Sail from the Sun" is set in a river bank.
3. In the lyrics of "Sparkling Red Star", "The small bamboo raft is in the middle reaches of the river and walks on both sides of the towering green hills".

4. "A strong wind blew the well outside the fence last night." The well was blown away and the fence was used as a reference.
Third, the theoretical knowledge of heat and molecular dynamics in ancient poetry
1. In Lu You's Village Living in Mountain Happiness, "the flowers smell like sudden warmth, and the sound of magpies passing through the trees is like a new sunny day". The "fragrance of flowers" in poetry is the result of irregular movement of aromatic oil molecules secreted by flowers, and temperature affects the intensity of molecular movement.
2. In Zhang Xu's Stay in the Mountain, "even if there is no rain, the clothes are stuck in the depths of the areola". -Dew formation (liquefaction).
3. Bai Juyi's "Mu Jiang Yin" "Poor September is late at night, dew is like a pearl and the moon is like a bow"-the formation of dew (liquefaction).
