I Exchange For Black Technology By Blowing Up The Bully
Chapter 89: Introduction To Topology
Ridiculous, what identity do you have, dare to comment on my Mathematics Emperor... Teacher? !
Song He got up quickly, "Teacher Zhai!"
Standing behind him was Mr. Zhai Zhu, wearing glasses and smiling.
There was an evening self-study before, and Song He was taken to the office by Ban Jianye to do the test book. At that time, teacher Zhai Zhu happened to be working overtime. After witnessing his amazing mental arithmetic speed, he offered an olive branch on the spot, hoping that Song He would choose the rocket class she led.
Song He admires her very much, she has such a keen eye, such a bright eye, she can identify the most potential students! Teacher Zhai Zhu is really Bole, worthy of being a famous teacher!
"I just saw you sitting here studying, and I wanted to take another look at your miraculous mental arithmetic, but I didn't expect you to be learning topology." Zhai Zhu sat down next to him and put a stack of lesson plans on the table.
"Is the teacher's topology difficult?" Song He wondered.
"Topology and geometry are very different. They are more abstract mathematics. If geometry is a clear photo, topology is Van Gogh's "Starry Night." Zhai Zhu said with a smile, "According to the teaching experience in the past years, most of the students in the competition team will be stuck in the Topologically, it even includes top students like Chu Long and Qiu Lingshan."
"Chu Long got stuck for about a week before getting started, and Qiu Lingshan took a full month." Zhai Zhu recalled.
Song He was a little shocked. Of course Chu Long and Qiu Lingshan knew that the existence of the two great gods on the math team made other students look up and break their necks!
I originally thought that the learning path of the great god would be smooth, but I didn't expect that there would be difficult hurdles to overcome.
Song He was in a bad mood. He flipped through the math competition book in his hand, and there were 80 pages of topological questions!
If you are also stuck by the topology, even if you are stuck for a few days, the Kungu King boss battle will directly fail! There is no play in the top ten!
Bad, is this wave really going to lose?
"Tonight's lecture in the auditorium, I will be in charge of the lecture, and I will specially introduce you high school competition students to understand topology." Zhai Zhu smiled.
"In the last two weeks, I will give several lectures in a row. After you listen carefully, you can get a first glimpse of the topological problems after two weeks."
"No, teacher, I'm in a hurry!" Song He showed embarrassment.
"Hurry?" Zhai Zhu was taken aback.
"I want to grab the Kungu King reward for mathematics. I'm going to do it this week. Nearly half of the math problems in this issue are topology. I have to learn all of them before the weekend!" Song He frowned.
Zhai Zhu smiled and shook her head lightly, "It's good to have a fighting spirit, but it's not practical."
"The math book you got is for third-grade contestants. They have learned it in the second and third grades of high school. You are just getting in touch with it for the first time, so you will definitely suffer."
"It's completely unrealistic for you to compete for the top ten with the old students who have studied for one or two more years. Learning to guard against arrogance and impetuosity requires steady progress year after year."
Song He's head buzzed when he heard the words "one year and one year", wondering if he has to wait another year? How can I wait so impatiently? Cucumber dishes are cold!
To enter the top ten, we can't wait for next year and the next year, just this week!
Teacher Zhai Zhu is talking about the growth time of ordinary people, not for me, the emperor of numbers! I want to learn how to break the endless heavens! Prove it with strength!
Song He ignited his fighting spirit, called out the system cruelly, gritted his teeth and bought a comprehension capsule.
20,000 grievances per piece, such an expensive trump card, can only be used in difficult times!
He pretended to drink water, swallowed the Lunwu capsule, and raced against time to lay down on the test book, and charged at Topuo!
Beside, Zhai Zhu looked at Song He who had entered the state in surprise, smiled helplessly and shook his head.
Many years of teaching career, bits and pieces of memories appeared on her spectacle lenses in a trance.
Back in the day, Chu Long and Qiu Lingshan were so unwilling to admit defeat!
At that time, Zhai Zhu clearly told Chu Long and Qiu Lingshan, "Topology is difficult, don't rush and take your time."
Chu Long's left ear went in and his right ear went out, and he stayed up all night crazily for several nights. His body was exhausted and his body was exhausted. After just one week, he managed to overcome the intermediate difficulty topology problem, which shocked the teachers in the mathematics group at that time. a handful!
Qiu Lingshan didn't say anything at the time, but she also frantically did topological questions in the evening self-study. When she encountered a topic she didn't understand, she bit the pen, and finally lost the cap of the pen, suspected of accidentally swallowing it during the thinking process. She finally solved the medium-difficulty topological problem a month later.
As for the other contestants...
Some people used it for half a year, some used it for a year, and more contestants could not get a glimpse of the topological method until they graduated. They missed the provincial award and ran to the world with hatred.
Thinking of this, Zhai Zhu felt a little sad.
There are pits in other disciplines, big and small, and many people at the bottom are trying to climb up.
And mathematics is a cliff, dark and bottomless, and only a few gods fly in the air.
She turned her head to look at Song He, as if seeing Chu Long and Qiu Lingshan back then.
Young people are always full of anger and want to become fat in one go. But reality will teach them not to rush, to take their time.
Zhai Zhu was secretly looking forward to the emergence of talents from generation to generation. I don't know how long it will take for Song He to get started with Topology? a week? two weeks?
She stopped thinking about it, opened the lesson plan, and started preparing lessons.
At the same time, Song He has entered a state of ecstasy!
Under the double blessing of comprehension capsules and mental arithmetic capsules, the brain is like a molten volcano, suppressed by huge energy, and will break ground and erupt at any time!
A large amount of knowledge is captured by the eyes, flows into the brain, crushes and breaks apart the understanding.
Geometry and topology are similar, but different.
In the field of geometry, a sphere is a sphere, and a cube is a cube. They are completely different concepts and require completely different formulas.
But in the realm of topology, a sphere and a cube are exactly the same, because they can be bent or stretched from one to the other without cutting or tearing.
The dough on the chopping board appeared in Song He's mind. The white dough was kneaded continuously and turned into various shapes, but it was still the same dough in essence.
Continue to school.
In the field of topology, there are essentially only two types of one-dimensional space: straight lines and circles. A circle can be twisted back and forth, but it cannot become a straight line as long as it is not cut off.
For two-dimensional definable surfaces, the genus classification is used, and the genus is a hole in human words.
For example, if there is no hole in the sphere, the genus is 0, and if the donut has a hole, the genus is 1.
The donuts are so delicious. Song He was distracted for a moment, then shook his head and returned to mathematics.
As time goes by, the knowledge of topology in my mind has accumulated more and more.
The comprehension capsule shows great power, and each absorbed knowledge point is like a seed, taking root and sprouting, and growing more and more branches. The branches gradually touch each other and become densely entangled, forming an impenetrable jungle of knowledge!
Song He felt very refreshed. When he first started learning topology, it was like breaking into a vast white nothingness, but now the jungle of knowledge is getting wider and wider, and it is full of vitality!
"It seems...it's not that difficult?" He muttered to himself.
Some inexplicable thoughts gradually emerged, and he frowned, writing and drawing on the draft paper with a pen.
Many weird images were drawn by him, like countless bubbles, gradually filling the paper.
If it weren't for the math book in front of him, he might be mistaken for a mental patient painting, after all, the painting is really inexplicable.
Next to him, Zhai Zhu finally finished the lesson plan, heaved a sigh of relief, packed up, and prepared to leave with his bag.
Suddenly, she turned her head and saw Song He's draft paper.
Can't learn anymore, drawing to pass the time? The corner of Zhai Zhu's mouth curled up into a smile, he didn't expect this child to have a cute side.
But then, Song He uttered a word, which completely froze Zhai Zhu's smile, and set off a storm in his heart!
