Chapter 33: explore

In the middle of the curtain, a smiling old man appeared.
He wore a very simple navy blue tooling, behind a white wall, sitting on the sofa, his smile as plain as his clothes, only intimate.
He didn't have a speech, but his release was completely different from that of Vice-President Zhang. He didn't seem to plan what he wanted to say. He just spoke to the camera and said: "Sorry, everyone is sorry. Seeing you, it seems to have a sense of distance, but I think that such a distance should make both of us feel relaxed."
The old man was very sincere, and all the students in the auditorium looked up to his face and showed a relaxed smile.
He said: "In fact, I am a very shy person. I want to talk to a lot of people. I always have to do psychological construction for a long time. Therefore, the organizing committee proposed that I can use video to convey my heart to you, my The first reaction is, God, this is really good."
He was intoxicated by the exaggerated smile and infected all the children in the audience. The children and the big children all laughed, and the old man laughed himself. His eyes were loving and his eyes were shining.
After a while, he continued: "At the time, other teachers should have said a lot. The meaning of this summer camp is good, and the purpose of learning is all right. Anything that can be done cannot be done. Some people will be blinded, thank you. They don't have to repeat these very complicated things. So what do I want to say, okay, in fact, I don't want you to say that every time I make a similar speech, my initial impulse is to tell you how much I love. Mathematics, I will not hide my telling you that I love her very much, she is so delicate, wonderful, profound... But she is such a very interesting thing, no matter how much time I spend with complicated language like you describe, it is far will not be enough."
The old man is fascinated, talking about mathematics, he smiles more brilliantly, like a fire in his chest, infecting everyone in the venue.
"So, when I was very young, my father told me a picture when I was sleeping. Imagine that at the beginning of this world, it was dark. The so-called beginning is very early and very early. Before the birth of mankind, long before the birth of the dinosaur, before the formation of the earth. The so-called black, not any kind of spices you have ever seen can be painted black, it is no light, then it is still There was no light. Then something happened, an extremely small and tight point exploded, it flipped inside, time spread, space spread, and the world we know and don’t understand begins For a moment, they continued to extend, which was an extension of time and space, and passed through countless years. After a long time, the small group of gas gathered gradually brightened, we called it the Milky Way, and later, the sun appeared and the earth formed. And then, after countless years, on a very small planet, someone opened his eyes."
The voice of the old man gradually calmed down. He squinted slightly and his voice was as pleasant as a piano: "The man is you, and the time is in a very deep night. You look up at the wonderful starry sky. The stars are shining and magnificent. Some people tell You, that is the universe."
On the curtain, the old man smiles still, with the brilliance of profit. There was no more sound in the entire auditorium. There was silence all around. All the children looked up. They were watching him. They were also watching the world he brought. They were surrounded by the universe and silent.
The silence of thought continued for a while, and the old man smiled: "When I was young, the picture that my father told me really made me feel very good. It was so interesting in my real world. But then, I read high school, I went to college, and I gradually got more knowledge. At that time, I realized that every time my father told me, it may be truth or fallacy. It is the cause of our universe. Some kind of speculation is still improving. Maybe it will be confirmed one day, or it will be overthrown one day. It is possible. You see, we are standing on the edge of knowing and unknown every day. If we look at it, the world is too big, and we know too little, everything seems to be uncertain, which is very frustrating. But what I want to tell you is that the unknown is the most wonderful thing."
The old man said here, sitting up straight, he is closer to the camera, and his face is more beautiful.
"Human civilization has experienced a long night, and in a moment in the night, thinking collides with sparks. Our ancestors created the number 1. From 1 onwards, the concept of human abstract logic is formed. If the world we first saw is so big ..." The old man smiled and put his thumb on his forefinger, compared to a very tiny gesture.
He smiled and said, "So after that, we gradually realized that the world will always be bigger than we think. For thousands of years, countless sages have gone on and on, and constantly perfecting this subject. It is no exaggeration to say that it is mathematics. Opening our eyes gives us the opportunity to see the tools of the entire unknown world; it is mathematics that bridges between seeing and knowing."

Mathematics is a tool, it is also a language. You may feel hard in mastering this tool or language, but believe me, these efforts and hardships are worthwhile compared to discovering the unknown fun. Once you are aware By the way, we are just a small human on a small planet, but trying to master a thing that can understand the truth of the universe, you will suddenly realize that the process of your own learning is great enough!"
The old man paused. He smiled and licked his lips, feeling like he was too much and shy.
Lin Zhaoxi looked at him again.
He was already awake, and he was looking up at the little face and staring at the old man on the screen. His eyes are still clear, but there is a kind of ecstasy that has never been seen before. If you start from this time, you want to be his student and work hard for many years, which is also very remarkable.
Lin Zhaoxi smiled from the heart.
The last voice of the old man came from the speaker. He said: "If you have any problems in your studies, you can ask your teacher or email me. I sincerely hope that you will feel the joy of learning mathematics. I wish you all a happy time in this process."
A line of e-mail addresses was printed on the screen, the picture faded, and some people began to applaud, but most of the entire auditorium still fell into a deep silence.
Suddenly, the old man in the picture raised his head and smiled again. He looked at the camera and patted his head and smiled. "Forget to say, I will prepare a small topic for all of you. If anyone in you can answer it, welcome. Send me the answer through this email address. But believe me, even if you solve this problem, you can't immediately represent the competition, and you won't get any rewards. This is just a delicious dessert in your hard work every day, hope. You can taste a bite, it's fun."
The old man's face finally disappeared and a cross board appeared on the screen.
The problem was also played at the same time -
According to the rules, how many steps are required to empty all the pieces outside the middle position? And list your steps.
In front of the auditorium, there were already staff members who got up and picked up a few unremarkable boxes. They took out a small wooden box from the inside and distributed it.
The children who got the wooden box were very excited. They didn't expect to receive gifts at the meeting. Some people shook the box hard, and some people opened it directly, giving a pleasant laugh.
The chess box was passed down one by one from the left seat of the seat. Lin took a box and gave the remaining stack in his hand to him. She opened it and found that it was the same cross on the screen.
There are 33 depressions in the cross, and 32 squares are placed in the depression, only the middle one is empty.
There is a small note in the chess box, indicating the rules.
1. After all the pieces are full, take out one of the central ones.
2. The can only skip the adjacent pieces to the vacant position in the horizontal direction (not obliquely).
3. The skipped piece is eaten.
4. Continue to move according to the previous method, until the end can not go down, there are still a few pieces left.
5. The less the remaining pieces, the more powerful. If there is only one left, then you are a genius.
Lin Chaoxi once again looked up at the problem on the screen - according to the rules, empty all the pieces outside the middle position, at least how many steps?
She looked at the little boy next to her again, for a long time without words.
He has already opened the wooden box to play with it, the light is dim, and his white and tender face presents an excitement that has never been seen before.
Suddenly, Lin dynasty recalled a moment that happened in the future. The adult squat stood under the steps and asked her two terms she had never heard before.
"Fisher linear discriminant function?"
"Classification of complete solutions?"
At that moment, she stroked the warm wooden chess box in her hand as if she realized what was in the dark.
Kong Mingqi, optimal solution, travel business problem... fisher linear discriminant function, complete solution classification, pnp problem...
Everything starts here.
The author has something to say: In the past two days, I will try to add another one. I hope I can fix it at 7:00 in the morning.
