"Yu beauty" is used to compare the methodology of calculus: combining finite and infinitesimal, to solve infinitely infinite problems through a limited and poor way. Between abstract and concrete transformations, high numbers and poetry interactively.
this is almost a resonance in aesthetic sense. Pan Dingkun said that high numbers are beautiful and poetry is beautiful. They are also refined, deep and regular.
he sits in the small chair of the sitting room, raises his head, slightly sway: "the gale rises and clouds are flying." The light of the setting sun shone on his face through the window, reflecting a strange light in his pupil.
the Chinese dictionary in the bookcase. When the surging news reporter Zhang Wenli
out of a mathematical teacher's aesthetic vision, he is especially fond of regular verse and regular metrical verse. "The desert is straight, the long river falls." "The spring silkworm comes to the dead, and the wax torch begins to dry." He could not help but say, "how good is that poem, so concise and so incisive?"
the more cherished, the more anxious. Before the death of a Shaanxi writer, he saw the couplet and felt sorry for the war. He broke his finger, and in modern times, Lu Xun wrote that he had written "the fingers of the thousand men and the children of the young"; he had forgotten all his books, but the couplets in it remembered that "the walls of the reeds were light and shallow, the tip of the bamboo shoots in the mountains were thick and hollow".
can the beauty of rhyme, confrontation, and oblique tones be written later? "The new generation will not write. Only the old ancient poetry, will they not become fossils?" Pan Dingkun asked. His wife died in 2015. Since then, he has read "ten years of life and death two boundless. The heart is the dismal desolation.
Pan Ding can feel that every era should have a good poem which can express the heart: "such a good thing can not be in the hands of our generation." Think about it, he found the school Propaganda Department: next lecture, do not talk about calculus, change poetry.
unexpectedly, he quickly brushed up his attitude in ancient poetry, which was more intense than the mathematics lesson he had devoted all his life to teaching. The people in the Propaganda Department looked for him and said a few more times. He said he did not dare to agree. After all, he was not a professional or an amateur. "But I didn't promise to, but I was secretly prepared." He laughed, like a child who stole the candy.
and he rose and said, "I'll show you something." A small step goes to the bedroom. I came back with several large sheets of paper, some of which were added with symbols of reduction, and others painted red circles.
this is the writing of the Chinese dictionary, which is written in the Chinese dictionary. He is always talking about it: where to fight, where to extend, and where to avoid being alone. It has also been summed up as the rule of "eight words and four points of attention".
"why do I know these rules?" Because I read math. He is happy. The errors of calculus are divided into main parts and minor parts. There are occasional exceptions to the first sentence in the rule of equal oblique tones, just like the minor parts. Some of the symbols on the paper are reduced or reduced, and some can even observe the central symmetry, which is the concept of mathematics.
Pan Dingkun said he wanted to simplify Chinese rules and become popular. Let children learn poetry first understand the rules, and then recite. "Nowadays, teachers only talk about artistic conception and do not talk about rules." He sighed. Also said that he is stupid, one can not sing, two can not dance, three do not play chess, four can not ride a bicycle, love to nest at home, read the book. A book that has been read for 80 years can't be read in white.
Zhou Benbo, who was the deputy director of the high school of Xi'an University Of Architecture And Technology, remembered that Pan Dingkun said in the lesson of the ancient poetry, that if he died of a fire, it would not. "We must save (ancient poetry), we must let young people know (rules). I think this is a teacher's feelings, he has the responsibility to inherit this culture.
Pan Ding King remembered that one day seventy years ago, when he visited professor Zhao Songqing's home, the strange teacher left "the relationship between mathematics and poetry" and left him a comment: "
" Mr.Pan (Mr. Pan), you have a brain to be a teacher. "
Pan Dingkun sent calligraphy works to the school. The surging news reporter Zhang Wenli
