Mathematics is also a very cultural subject. In mathematics, we know how to solve equations and how to answer a question. This is the charm of mathematics. Below is a handwritten newspaper on mathematics culture that I brought to you. I hope you like it.

1 , Mathematics Quotes
1 Elementary mathematics is one of the most representative creations of modern thought. Its characteristic is that it connects theory and practice through direct channels. ——Whitehead
2 History makes people wise, poetry makes people elegant, mathematics makes people noble, natural philosophy makes people deep, morality makes people steady, and ethics and rhetoric make people good at argument. . ——Bacon
3 The first is mathematics, the second is mathematics, and the third is mathematics. ——Roentgen
4 The incomparable permanence and omnipotence of mathematics and its independence of time and cultural background are direct consequences of its essence. ——A. Ebo
5 Infinite! No other question has touched the human heart so deeply. ——Hilbert
6 Mathematics, the queen of science; arithmetic, the queen of mathematics. ——Gauss
7 The value of mathematical knowledge to us is not only because it is a powerful tool, but also because of the perfection of mathematics itself. In the internal or external development of mathematics, we see the purest logical thinking activities, as well as the aesthetic expression of the highest level of wisdom and vitality. ——Prinhim
8 Mathematics is a deductive thing that does not appear suddenly. Daily training is very important. You must look at it from a high point and change the situation and conditions. , or looking at it from a higher level, it’s just a new thing. ——Li Xinming
9 The essence of mathematics lies in its freedom. ——Cantor
10 Music can inspire or soothe feelings, painting can make people happy, poetry can move people's hearts, philosophy can make people gain wisdom, science can improve material life, but mathematics can give all the above. ——Klein

3. Interesting Mathematics Question
Strange Numbers
The math teacher asked his students: "Is there such a six-digit number that can be used to multiply 1, 2, 3, 4, 5, 6, the resulting six-digit product is still the same six-digit number, but the order is slightly different?"
Is there such a strange number? The students found it hard to believe.
"Yes. There is such a six-digit number. Now I will write it down. You can multiply it by 1--6 and see these six interesting products. This is a very Interesting thing." The math teacher finished and wrote the six-digit number on the blackboard.
Children, you must want to know that six-digit number, right?
Interesting natural numbers
The sum of five consecutive natural numbers is 350. What are the numbers of each of these five natural numbers?

De Broglie's formula
The eighth stamp commended The formula is the de Broglie formula that expressed wave-particle duality proposed by de Broglie in 1924: λ=h/mv,
where λ is the wavelength of the material wave accompanying the particle, and h is Planck's constant, mv is the momentum of the particle. Before de Broglie, people's understanding of nature was limited to two basic types of matter: physical objects and fields. De Broglie originally studied history, but changed to science under the influence of the mathematician Poincaré. In 1924, he proposed the concept of "matter waves" in his doctoral thesis, which shocked the world. He believed that any physical object or particle has both wave and particle properties. He also used Einstein's theory of relativity to derive the formula for the wavelength of matter waves. . His view was later confirmed by Davidson's experiments. The concept of material waves also provides an important theoretical basis for the development of wave mechanics.
Boltzmann's formula
In 1854, the German scientist Clausius first introduced the concept of entropy, which is a quantity indicating the degree of disorder of a closed system. Entropy is the Greek word " change" means. This quantity will not change in a reversible process, but will become larger in an irreversible process. Just like a lazy man's room, if there is no one to tidy it up for him, the room will only become messy and will never become tidy.
Living things are also inseparable from the "law of entropy increase". Living things need to absorb negative entropy from outside the body to offset the increase in entropy. In 1877, Boltzmann used the following relationship to express the degree of disorder in the system: S=kLnW, where k is Boltzmann’s constant, s is the entropy value of the macroscopic system, which is the degree of disorder of molecular motion or arrangement. measurement scale. W is the number of possible microstates. The larger W is, the more chaotic and disordered the system is. From this we can see the microscopic meaning of entropy: Entropy is a measure of the disorder of the thermal motion of molecules within a system. Because of his novel viewpoint, it was not accepted by many famous scholars at first. Boltzmann paid a huge price for it, which became an important reason for his personal tragedy and suicide. Boltzmann's tombstone is engraved with this formula S=kLnW in recognition of his great originality.
Tsiolkovsky formula
Chang'e flies to the moon and thousands of households fly into the sky. Human beings have long been yearning for space and have been making unremitting efforts for this purpose. The key to conquering space is rocket technology.
When it comes to modern rockets, we must mention the world-recognized pioneer of aerospace theory, Tsiolkovsky of the former Soviet Union. It was he who proposed the possibility of using rockets for interstellar navigation and launching satellites. And established the relationship between the structural characteristics of the rocket and the flight speed, which is the famous Tsiolkovsky formula. Among them, V is the velocity increment of the rocket, Ve is the velocity of the jet relative to the rocket, and m0 and mi represent the mass of the rocket when the engine is turned on and off respectively. It became the key to mankind's conquest of space.
In 1957, the Soviet Union launched the first artificial satellite, ushering in the space age. In 1961, it launched its first astronaut, Gaijalin, winning the first battle of the space race. The United States won the first battle of the space race in 1969. Send Armstrong to the moon. Tsiolkovsky focused on studying ancient Chinese rocket technology and asked people to translate military works from the late Ming Dynasty and early Qing Dynasty for reference. He was especially interested in the "Arena of Arms". At that time, China already had nearly 30 types of military rockets. Weapons such as the "Magic Fire Dragon Arrow" or the "Fire Dragon Out of Water" fascinated him. He had more dreams and inspirations, and soon wrote "Dreams of Earth and Sky". Book. He has a very insightful saying: “The earth is the cradle of mankind, but man cannot live in the cradle forever.
