Why don’t mathematics departments teach advanced mathematics?

1. The King of Funny

When I first entered school, every student in our class laughed wildly at a humorous and funny male classmate. Let me tell you, that is the funny king of our class - He Ruoan. Because of this, the classmates in our class gave him a nickname, "Poached Egg", and some classmates called him "Poached Egg".

In physical education class, our "Poached Egg" classmate suggested playing a game of puppets. Whoever moved would go on stage to tell jokes. Everyone clapped their hands and applauded. Another point: everyone must laugh at the joke. If one person doesn't laugh, he loses. The game started, our "Poached Egg" classmate moved deliberately, and the classmates who were making a loud noise also stopped. Suddenly, there was silence in the classroom. When classmate "Poached Egg" saw that everyone was quiet, he started telling jokes. "The joke I told is called "I'll settle a score with you."" This whetted the appetite of the students. He began to talk: "Once upon a time, there were a pair of twins, one called looking for you and the other called settling accounts. Because their parents were very busy at work, they found a nanny to take care of them. One day, the nanny took them out to play, and suddenly, Both of them disappeared, so the nanny came to the police station and asked who she was looking for. The nanny said, "I'm looking for you!" "Wow hahahahaha, suddenly, the whole class burst into laughter, no one did not laugh. From then on, he became the funny king!

Not only can he tell jokes, but he also has excellent academic performance, especially in mathematics. He has written a glorious chapter in the history of mathematics in our grade. When he was in grades 1 to 3 (from the time he entered school to the present), he was first in the class in almost every exam, and sometimes first in the grade. However, now, he may not be the same anymore. I am his strongest competitor. If I am not the first, he is the first. Anyway, we all "take turns". Although his academic performance is good, he looks stupid and looks stupid. real!

He is now the funny king who will never rotate in our class. Congratulations.

2. A funny class

As the wonderful bell rang, class started. The fifth period Chinese class has begun.

Just as the students were finishing reading the first lesson, Teacher Chen came, "Please open the Chinese books and turn to the third lesson." Teacher Chen's loud voice sounded. "Today, let's write a diary together." Take out the diary, open it and write the date. Then he started writing. Today we are going to continue writing a children's poem, "Start!" As soon as the teacher's voice ended, there was a rustling sound of writing in the classroom.

Writing and writing...the rustling sound of writing stopped when the teacher said "Stop." The students began to read the diary aloud.

I finished reading, and Teacher Chen said that I wrote well. I was very happy. The students read it one after another. I read and read, and finally finished it. Now I am waiting for the teacher to take it up for correction. It will be finished in a while. The teacher said: "There are a few students whose compositions are full of loopholes. Let me read them." After that, the teacher started to read: "A classmate wrote about dancing trees. Is this a tornado?" Oh, it was written by the monitor. "Another classmate wrote that when the wind blows, dust rises and garbage flies all over the sky. Is this a sandstorm or a typhoon?" Oh, it was written by the squadron leader. "There is also a red flag written by a classmate fluttering in the wind. Is this the red flag pole broken?" Oh, it was written by the group leader.

After reading, the whole class burst into laughter. Some students laughed so much that they bent over, some students laughed so hard that they slapped the table and stamped their feet. Some students clapped their hands and said good, and some students laughed so hard that it hurt. Suddenly, the bell rang, and we had a joyful lesson in laughter.

3. A love letter from a mathematics student

Dear Shu Xue:

We have known each other for almost four years. Tonight, when I looked stupidly at the scattered stars in the sky, your name almost occupied my whole heart like an irrational number on the real number axis.

You are so beautiful, even the most beautiful fractal pattern in the world is not one ten thousandth as beautiful as you. The long shawl hair expresses the one-dimensional manifold vividly; the face with a pair of dimples puts the two-dimensional curved surface of the world to shame; the graceful figure makes all the x-axis, y-axis, and z-axis fascinated.

You are so pure and kind, as simple as a simplex. From the first time I met you, you became the center of my whole life. You will always be so special in my heart, just like 2 is the only even number among prime numbers.

I want to be your satellite, watching you journeying in my own orbit. Although sometimes it is close and sometimes it is far away, it is always around you. I want to be your dual space and carefully record every bit of your temperament. I want to be your companion matrix. If you degenerate, I will also degenerate; if you are reversible, I will be reversible. Every morning when I get up, the first thing I do is to recall your characteristics. I want to keep you firmly in my heart. Every time I eat, I will think about your "norm" to avoid having a bad appetite. Every night, I can't help but give you a series of sine waves, so that I won't lose sleep; every day in my dreams, I will wander in the trust zone in my heart, where every picture of you is stored.

When we looked at each other, I felt a warm current circulating in my body. Our hearts must be connected, and no change can separate us.

Since I met you, I have understood the meaning of frequency. It is to record the feeling of my heartbeat when I see you; since I have met you, I have understood the meaning of disorder, which is you. The image in my mind when you smile at me; since I got to know you, I have realized the role of infinity, because any real number is not enough to express how much I miss you. I finally know the connotation of extension. Even the puppies you raise and your anger when you act like a baby are extremely cute. I finally know the mission of logic, which is to prove that the union between you and me is an eternal proposition; I finally know the essence of isomorphism. You and I are like Romeo and Juliet, but this is not isomorphism, because you and I are comedy.

If someone asked me which is the most lush tree in the world, I would say it is the poplar tree that became our matchmaker when we first met. If someone asked me which is the most touching picture in the world, I would say it is the shot of you sleeping sweetly on my shoulder on a long bus.

Do you know what my greatest expectation is? It's your love. You know what my biggest worry is? I'm afraid your love will be too different. But even in the trough of the wave, I will always chase you and converge towards you like the Cauchy sequence. But this is definitely a zero-probability event, preferably an impossible event.

You are in my heart just like the Fields Medal is in the hearts of mathematicians - a lifelong ideal and a lifelong pursuit.

If you want to ask me how committed I am to you, I will tell you that it is just like a mathematician conquering Fermat's last theorem - unswervingly.

If you want to ask me whether I will change my heart for you, I will tell you that this is like the proof of Goldbach's conjecture-a long way off.

I love you, Shu Xue!
