"Song history according to? According to the records of the aristocratic families in Shu, Meng Chang, the master of Shu after five dynasties, wrote a couplet of "New Year's Qing Yu, Holiday Changchun", which was hung in the palace to pray for spring and was cited as the first example of the couplet by later generations. Since the Ming Dynasty, the custom of using couplets has become more and more popular, which is not only loved by literati, but also widely entered the homes of ordinary people. The contents of couplets are all-encompassing, or travel around the mountains, or sing praises to the scenery and express feelings. When I don't know about physical knowledge, couplets are more profound and interesting.
Optics in couplet
Song Xiang was a gifted scholar in the late Qing Dynasty. He has a sister-in-law who is also very talented. One day, my sister-in-law will take an examination of her brother-in-law. "People say you are a gifted scholar. I think it's a little exaggerated. Today, I dressed up in front of the mirror and came up with a pair of couplets. Please answer them correctly and give me a solution. " Song Xiang said haughtily, "Go ahead, continue the couplets, and come casually." Sister-in-law smiled and unhurriedly said the first part:
Double mirror hanging platform, one woman dressing on three sides.
Hearing this, Song Xiang himself was surprised. He thought for a long time, but he couldn't agree. He regretted saying those big words. At night, when it is dark, the lights are on at home, just like a guest saying goodbye, and the guests are sent off and bowed at home. This gesture is reflected on the wall and a shadow appears. Inspired by this scene, Song Xiang jumped up and down with joy and repeatedly said, "I found the bottom line, sister-in-law, listen-"and read the bottom line:
A solitary lamp hangs on the wall, and two people bow their heads.
This couplet is not only perfect and vivid, but also uses the plane mirror in physics to image in the first part, and uses the knowledge of light propagating along a straight line to form shadows in the second part. I'm glad to introduce it to my classmates in class.
There is another link:
The sky is close to the top of the mountain and farther from the mountainside;
The moon floated on the water, but when it reached the bottom, it sank.
The spread of light and the application of the principle of plane mirror imaging are more instructive, warning us not to aim too high in our study, but to be impetuous and down to earth.
Mechanics of two couplets
The ship carries stones, while the ship carries stones lightly and heavily.
The staff measures the ground, the staff is short and long, and the short quantity is long. "
Buoyancy is applied to "ships carrying stones". "Ships are lighter than stones" means that the density of wood is less than stones. Downlink knowledge applied to length measurement. Look at another pair of couplets: the lights turn off charcoal and blow red. "The boat is full of water." The boat has more and more water in the water until it is even with the water surface. It should be the principle of the communicator. "Blow out the lamp" is because the ignition point cannot be reached by lowering the temperature, and "charcoal blows red" is because the oxygen content increases.
Third, electricity in couplets.
This couplet is a couplet when a math teacher and a physics teacher got married. Clever integration, not interesting. Li Anyun:
Great circle, small circle, concentric circle, heart to heart.
Negative electricity and positive electricity attract each other.
Horizontal criticism is: the law of justice.
Judging from the subjects taught by them, geometry in mathematics and electricity in physics are skillfully combined. Although far-fetched, they also complement each other. It seems that the new curriculum standard also embodies the idea of changing the subject standard, integrating the knowledge of various disciplines and improving the scientific literacy of citizens.
Thermology in quadruple
After four years of private school, Wang Erlie went to Longquan Temple to do odd jobs, and whenever he was free, he asked a learned monk for poetry. One winter it snowed heavily, and the young monks and handyman in the temple came to sweep the snow. They even played while sweeping and made a Guanyin statue out of snow. At this time, the abbot monk Kong Yuan came to him and wrote a couplet on the snowman:
Snow accumulates Guanyin, and sunrise incarnates the South China Sea.
Let the young monk make a couplet. Listen, young monks, look at me, I'll look at you, shaking my head and scratching my head. At this moment, Wang Erlie aside said "I'm right", and then casually read aloud a way:
Clouds pile up like arhats, and the wind blows west.
The couplets are vivid and inspiring, and they are really ingenious. Isn't "Sunrise incarnates the South China Sea" a typical melting phenomenon? It also involves the formation of snow and clouds, one is condensation and the other is liquefaction. You can also use atomic physics. Walking in the street with many shops, couplets of various companies compete to attract customers, especially restaurants. For example, it's ok to have a good drink outside. The delicious rice is like a good meal at home, attracting foreign guests from the cloud. Incense leads to the fairy wine in the cave, which is famous for three thousand miles beyond the Great Wall, and its fragrance is overflowing. It is famous for crossing the river with the white snake, an experimental instrument in the couplets on the 12th floor in the south of the Yangtze River. There is a red sun oolong hanging on the wall overhead, wearing 10,000 points of Venus. The answer in the first part is the oil lamp, and the answer in the second part is the scale, that is, the steel scale that we don't often use now, using the knowledge of lever. Oil lamps seem to be dying out, which can be compared with alcohol lamps. It feels a little wrong, but it can also be used. If this riddle comes out in class, it will definitely increase students' interest and deepen their memory. Why not? Walking into physics from life can improve students' interest and create a good atmosphere. Physics is a very interesting subject. If you do, say and do problems blindly, it will stifle students' interest in exploring nature. As long as we notice that the knowledge of physics is everywhere, from astronomical geography to religious practices, every corner can reflect the aura of physics, which can make our students interested in physics and keep it forever. Vivid image, the first part uses the plane mirror in physics to image, and the second part uses the knowledge that light propagates along a straight line to form shadows. It is interesting to introduce it to students in class.
