Chapter 307: Descriptive Mathematics

The car finally stopped, and through the window blue, we saw a very elegant school gate outside. It is a school gate building made of the planet's specialty stones. The car continued to start again. On both sides of the road, there were trees less than 20 meters in length, but these trees stood opposite each other. The protruding branches formed a tree-lined road. It looked like the car was passing through a green door.
The scenery with shuilan nodding is pretty good! The car entered a square and parked in front of a building. A voice sounded from under the car: "Miss Lian, please get off the car!"
Nian Lingling Dika got out of the car, and a person in black clothes gave Lian Ling Dika a backpack and said, "Here are some things you will use. I will take you into the classroom now."
The person led the way and said, "All the students are now in class, so the whole school looks quieter. This is your wrist card. The number on it is your student ID. You can go with it. Eat in the school restaurant. Your restaurant is on the top floor. Here are ordinary elevators, which are used by ordinary students. Here are three elevators used by people with identity like you. " Swipe the wrist card on a small bright screen. Lin Ling Dika swipes the wrist card on the left wrist there, the elevator door opens, and the two enter the elevator.
The elevator went straight up, and the man in black said: "It's already set here. Usually you only need to say the floor or classroom you want to enter the elevator! There are 100 floors in this building. I will pick you up at night. I My name is Wu Song. Your class is class S321. "The elevator stopped. Wu Song led Lian Ling. Dika walked towards the classroom of class S321.
Gestured Lian Ling. Dika swiped her wrist card on the door, Lian Ling. Dika swiped her left wrist card and the classroom door opened! A teacher stood in front of him and spoke to the student sitting below. When he saw the door opened, he said, "This is our new classmate, Lin Ling. Please sit down there!"
Teacher Yun pointed a finger at a side position. Lin Ling Dika walked over and sat down without saying anything. Then the teacher continued to say to all the students: "The only test scores we have for this time are the prize meter and Yu Tao. The other people don't have a top 20 in one grade. So how do you get into university! So This afternoon we will conduct a mock exam, three hundred subjects in three joint exams. Physics and chemistry are the main. You must be serious! "
Lilian Ling. Dika listened to the teacher's words like heartfelt words, and she was speechless on such simple knowledge on the planet. Would you like to encourage these students to learn? It's ridiculous!
老师 After the teacher said something more motivating, he started to explain the questions of the last exam. Behind the teacher was a large display screen, and those questions appeared on the real screen. Lian Ling. Deca is a bit weird. Why does this display have a blackboard name? Is it because this display screen is usually black?
Look at the table in front of you, this desktop is also a display screen! Now the content shown above is the same as on the blackboard! Here's how to explain these esoteric physics topics in a simple way!
学习 Studying the lessons here is a bit uncomfortable! And mathematics is even more messy. The mathematical system here turned out to be a basic system established thousands of years ago, and there was basically no essential development. For example cubic meters!
This is simply a joke. According to the definition of cubic meters here, a square two-cubic-meter object cannot be obtained at all. And once the cube is involved here, it is equivalent to walking into a mire. For example, ten cubic meters, you can't have the exact shape of ten cubic meters in your mind at all.
In the universe, mathematics is divided into computational mathematics and descriptive mathematics. I won't talk about calculation math here! Descriptive mathematics is the most commonly used in cosmic life. Descriptive mathematics is a way for people to have a concrete expression of the actual objects related to numbers.
2 cosmic cubic meters (2 meters long, 2 meters high, 2 meters wide). First of all, the cosmic cubic meters only describe squares. Such expressions can clearly make people know that this is a cube.
And clearly understand the size of this cube, and can form an accurate understanding in the mind. The beginning of mathematics was to count, and count was also a kind of expression for concrete objects.
If it is impossible to express specific physical objects, then this kind of mathematics should also evolve! Lin Ling Dika found that the people on this planet could n’t understand its real meaning for many concrete objects in the mathematics they used, and because of the problems of mathematics itself, most people on this planet gave up a lot of Math-related things, even avoiding simple mathematical logic.
Adults on this planet will know the land area of ​​their country, such as 7.2 million square kilometers, but when you ask him how big the 7.2 million square kilometers is, they will immediately look at you with a fool's eye, The fact is that they have no concept at all. If you ask 7.2 million square kilometers, can you stop a 3,000 km long and 4,000 km wide space battleship?
You will not get the correct answer. In the universe, the square of the universe is usually used to describe a specific square, 3000 square kilometers of the universe (3,000 kilometers long, 3000 kilometers wide), describing mathematics is an integral part of the life of the universe.
The development of this planet is slow. According to the judgment of Lin Ling Dika, the important link of description mathematics is missing. Looking at these funny math problems, Lin Ling. Dika couldn't help but bend her lips, and this time she has learned a lot!
These low-level civilizations have such a loose attitude towards serious science. When teaching, I believe that this civilization will not become a fourth-level civilization even after another 10,000 years! Lian Ling. Dika remembers that her teacher of cosmic physics once said that science can't be saved, and knowledge can't be kept private.
If the knowledge is to develop quickly, it is necessary to impart the latest knowledge to everyone who will learn. If a person learns wrong knowledge or simplified knowledge as soon as he comes up, he will need a lot of time to correct these wrong knowledge in the future, and he can still develop the knowledge there!
Therefore, the foundation is the key to knowledge transfer. Those who can learn can naturally learn, and those who cannot learn can never learn. But simplified knowledge is like a wrong road sign, always pointing in the wrong direction.
No matter how clever the mind is, if you learn too much wrong knowledge, problems will occur. Just as Lian Ling Dika thought, the bell rang. This is the bell for class.
Teacher Yun left the classroom very soon ~ EbookFREE.me ~ and all the students also left the classroom, which surprised Lin Ling Dika. When a classmate went out, he said, "It's terrible to go to dinner and have an exam this afternoon!" He said that there would be no one in this classroom!
Lin Ling Dika stood up, walked out of the classroom, and walked towards the three dedicated elevators. A person whispered behind him: "Why is this Lin Ling heading there, and she won't go up to see what she will do! Haha! "
A person said: "Ah! Forget it! The elevator is here, and you are ready to squeeze in! Otherwise it will be too late for dinner!"
Lian Ling Dika didn't care about these people. She stuck her wrist on the side of the elevator door, and soon the elevator door opened. Lian Ling Dika went in. There were already three boys in it. The three saw Lian Ling Dika was shocked, no one expected that people would come up here!
The elevator door closed quickly, and two more people got on the way. The five boys greeted each other. When the top-floor restaurant arrived, the five people got off the elevator first, and one of them who was on the way looked surprised at Lin Ling. Dika walked to the dining area alone, surprised to the three teenagers: "I thought it was you Take her into the elevator? I didn't expect it! "
A young man said, "You haven't seen her, except that her pink hair is dyed well, she can't even see her looks, and she's wearing the oldest school uniform, can't you see men and women at all! If I didn't know her, As a school uniform for women, she would be regarded as a boy. Who would have such a bad vision to invite her to eat on this floor! "
Lian Ling Dika didn't care about these people, but chose fried chicken. She didn't eat the food here, but these fried chickens can be covered on a plate so that she can take out the ring of existence. Enjoy the delicious fried chicken made by Chinese chef.
