Tian Wen is also very helpless. He has no musical expertise and can't play or sing. He is like ordinary people, except that he likes to listen to songs and sing a few sentences in his spare time. His music level is at best five-tone online, not out of tune.
As a part-time music teacher in the school, he has not taken a music class seriously. His title is only used by the school to cope with the quality inspection of the Education Bureau, so that the leaders will know that there is a music teacher in the 87 Middle School. As in some units, there is a reason to hire disabled people.
Moreover, Tian Wen only takes the salary of the math teacher and the performance of the class teacher who is on duty with an exceptionally 1,000 yuan. Other teachers would rather not be the class teacher than the bad class teacher. Therefore, the music teacher did not bring Tian Wen an extra dime.
However, he is a more serious person. Since he is a nominal music teacher, he doesn't talk about teaching and educating people-he is afraid of misleading his children, but he thinks that he needs to improve his personal music literacy to be worthy of this title. Besides, Principal Qian said, should the leaders of the Education Bureau make a surprise attack, should they come to our school to listen to a music class? Of course, this possibility is very small, not higher than 0.01%, and leaders have not come to investigate so far.
Tian Wen is steadfast in his affairs. For this 0.01% possibility, he calmly pondered music and carefully studied various music textbooks. He discovered that there seems to be a subtle connection between music and mathematics.
To put it simply, he seems to be able to use the laws of mathematics to compose music, even if he is a music layman and does not understand the science of composition at all, he wants to try music creation with his talent in mathematics and inspiration in music.
Tian Wen plucked up the courage to ask his supervisor if he could use this as the topic of his doctoral thesis.
His mentor also thinks that his research angle is novel, you can give it a try and praise him for being bold. But he also warned him that this subject is extremely difficult. Tian Wen must use mathematical laws to write a beautiful piece that is recognized by music professionals in order to prove that his argument is correct and his paper can be published. If he fails, he will definitely have to postpone his graduation, and he will definitely not get his PhD next year.
Recently, his thesis has encountered a bottleneck and stopped. He thinks hard every day, scratching his head and scratching his head. Except for class preparation and class, all his time is spent on it. He doesn't know whether the problem lies in mathematics or music. He looked at the manuscript paper that was blown all over the floor by the wind, and sighed. Everything really went wrong.
Seeing Teacher Tian's sad face, Ye Tang realized that these materials were his privacy. She didn't look at it any more, bending down to pick up the other papers.
The other students didn't move, they were all hanging up high. Chen Yumo hesitated for a moment, and followed Ye Tang to pick up papers. Cen Yannan put the rest on the table earlier and joined in.
Tian Wen stared at this scene in a daze, thinking that his eyes were dizzy, and the two most stubborn and disobedient students in Class 8 actually helped him do things? ! Yetang is cured, but Cen Yannan and Chen Yumo are also modified
The three gathered together the materials scattered in the classroom, and Ye Tang sorted them out and sent them to Tian Wen. She answered the teacher's question by the way, "Yes, I know Euler's theorem."
The surrounding students looked at each other. What is Euler's theorem? Who is Euler
Euler's theorem is the knowledge of basic mathematics in colleges. It is not a compulsory/optional mathematics content in high school. Teachers in some key middle schools will teach relevant knowledge in advance to prepare for high school mathematics competitions.
However, the 87 Middle School has not sent students to participate in math competitions for many years, because whether it is a university or a small-subject competition, their students have been brushed down in the preliminaries. Rather than becoming the laughing stock of other high schools, it is better to be self-aware to stay away from the game from the beginning, and save the registration fee and training expenses.
"How could you know Euler's theorem?!" Tian Wen didn't stammer when he said this sentence. One can imagine how surprised he was.
Ye Tang said lightly, "Of course I know, this is common sense, and I am not a fool."
After hearing the academic terms of Euler's theorem, they have been confused. Cen Yannan, Chen Yumo, and other classmates are all speechless collectively. Are they fools
A male student said dissatisfied, "Ye Tang, it's a good thing that you are cured, but why did you become pretending to be forced?"
Tian Wenheng glanced at the male classmate, "At...at school, note...attention...civilized language!"
The boy rolled his eyes.
Tian Wen is not angry, as long as the students scold him unclearly and breathe fragrantly, he will be content.
He said to Ye Tang, "Then you can talk about the content of Euler's theorem." In fact, he didn't believe Ye Tang could say anything.
"This theorem is a bit cumbersome to say. I have limited verbal description ability and have to write it down."
Other students slapped their mouths and concluded that Ye Tang was bragging and not drafting, and didn't know how to pretend to understand.
Tian Wen walked back to the podium patiently, put his paper away first, took out a piece of chalk, and handed it to Ye Tang. Whether Ye Tang said it was true or deceptive, he should give her a chance to prove herself, anyway There is half an hour of self-study early, without delaying the teaching of him and other teachers.
"You...you write Euler's theorem...write it to...show me, the truth is...practice is checking...the truth...the only criterion for truth..."
Ye Tang didn't take the chalk right away. She glanced at the different eyes of the students around her, Cen Yannan wanted to say something but stopped, Chen Yumo still looked surprised.
She smiled at them, then took the chalk, went to the podium, faced the blackboard, thought a little, and began to write strokes.
I haven't written chalk characters for too long, her writing is a bit distorted and naive.
A classmate laughed at her behind her, "What an ugly word."
Chen Yumo snorted coldly, "You write, it's not as good as her."
Ye Tang heard it, don't mind, she has self-knowledge, in terms of art, she really lacks a little talent, far inferior to Luo Xingchuan.
Euler's theorem involved in high school math competitions is usually related to plane geometry. A formula can be summarized: the number of vertices-the number of edges + the number of faces = 2.
The Euler theorem in Ye Tang’s cognition is a more primitive derivation, a property of congruence in number theory—this property is the basis of cryptography, and cryptography is the basis of computer system intrusion, she closes Eyes can deduce this theorem in dictation, but the steps are a bit complicated, at least a whole piece of draft paper should be filled.
So, she really wrote it silently on the blackboard...
