Re: 93 year old math professor returns to the podium to teach poetry: classroom is my paradise.
"look at the history of mathematics. Lu Xun said, "a miscellaneous family." Pan Dingkun himself said with a smile. He said that death formula is boring, so that students will be interested in knowing what role a formula plays in the natural sciences. Just like Professor Zhou Yutong once taught him how to place a person's historical research in the whole field.
he also plays an analogy with actors: "actors can't play the script back, they want to revive them. Teachers should also be revived. What are the theorems and formulas? The idea of living is to tell people how to create. " Pan Dingkun said, whether the teacher speaks well or not, depends on whether he has his own opinion.
in his class, advanced mathematics is no longer boring and unattainable, but begins to be flesh and blood and curious. Wang Fang, a student who listened to his class in the 80s of last century, has also been a teacher. She said, "if you are afraid of math and then suddenly find it is easier to accept, learn and study, it will give you great comfort and relief."
now she imitates him in class, and treats calculus as a way of thinking to students. He also learned to give examples, but he did not always live as he said. For example, with the hands hard to grip the egg is not broken, you can deduce a reasonable arch axis equation; the nature of the exponential function, Pan Dingkun said that his laundry is very water saving, each time rinse half of the water is half added, after ten times the degree of dirty is only 1/1024...
Wang Fang said that from the shallow to the deep, from deep to shallow, these two abilities are good teachers. She stood on the stage for many years and was still groping for Pan Ding's skills: "people teach you a trick, you spend your whole life."
"classroom is my paradise"
2011, 86 year old pan Ding, finally unemployed.
less than a year, Wang Jiwu, Secretary of the College of mechanical and electrical engineering, came to the door. There are always students who say that high numbers are hard to learn. He thinks that Mr. Pan, who is famous for his interest in stimulating students, wants to invite students to give lectures. Considering the age of the old man, he was hesitant and did not expect pan Ding to agree. On the day of
2014, CCTV5 broadcast the world cup special "I love the World Cup", and Pan Dingkun put the topic of the lecture as "I love calculus." After a while, he asked Wang Jiwu what "cool" means, and later the lecture became "calculus is really cool." When
2016, Wang Jiwu exchanged a few words with him, shaking hands and saying goodbye. After a few steps, he was called back by Pan Dingkun. He said, "I have been waiting for you to tell me to go back and teach your students." Besides, he said he was in good health and did not have "three high". I hope Wang Jiwu will not worry.
Wang Jiwu sighed: "he has the complex of being a teacher. His significance lies in communicating with students.
