First, famous mathematical sayings
1 Elementary mathematics is one of the most representative creations of modern thought, which is characterized by linking theory with practice through direct channels. -Whitehead
History makes people wise, poetry makes them elegant, mathematics makes them noble, natural philosophy makes them deep, morality makes them steady, and ethical rhetoric makes them able to contend. bacon
The first is mathematics, the second is mathematics and the third is mathematics. roentgen
The incomparable eternity and omnipotence of mathematics and its independent effect on time and cultural background are the direct consequences of its essence. -Abel
5 infinity! No other problem has touched the human mind so deeply. -Hilbert
6 mathematics, queen of science; Queen of arithmetic and mathematics. Gauss
For us, the value of mathematical knowledge is not only that it is a powerful tool, but also that mathematics itself is perfect. In the internal or external development of mathematics, we have seen the purest logical thinking activities and the aesthetic embodiment of the wisdom and vitality of the highest terrace. -Prince
Mathematics is a deductive thing, it doesn't pop up suddenly, and the usual training is very important. From a height, changing the situation, changing the conditions, or from a higher level, are all new things. Li Xinming
The essence of mathematics lies in freedom. -Cantor
10 Music can stimulate or soothe feelings, painting can make people pleasing to the eye, poetry can impress people, philosophy can make people gain wisdom, science can improve material life, but mathematics can give them all. Klein

4. Click on an idiom.
Answer: foolproof means there is no "one" and "ten thousand"
5. One, two, three, four, five, six, seven, nine, one word.

Third, interesting math problems.
Strange numbers
The math teacher asked his students, "will there be such a six-digit number?" Multiply it by 1, 2, 3, 4, 5, 6, and the product of six digits is the same, but the arrangement order is slightly different? "
Will there be such a strange number? The students find it hard to believe.
"yes. There are six such figures. Now I'll write it down. Multiply yourself by 1-6 and look at these six interesting products. This is a very interesting thing. " The math teacher finished writing and wrote these six numbers on the blackboard.
Son, you must want to know that six-digit number, right?
Interesting natural number
The sum of five consecutive natural numbers is 350. What are these five natural numbers?

De Broglie formula
The formula for commending the eighth stamp is De Broglie's formula for wave-particle duality proposed in 1924: λ=h/mv,
Where λ is the wavelength of matter wave related to particles, H is Planck constant, and mv is the momentum of particles. Before de Broglie, people's understanding of nature was limited to two basic material types: physical objects and fields. De Broglie originally studied history, but influenced by the mathematician Poincare, he changed to science. 1924, he put forward the concept of "matter wave" in his doctoral thesis, which caused a sensation all over the world. He thinks that any object and particle have the properties of wave and particle at the same time, and uses Einstein's theory of relativity to derive the formula of material wave wavelength. His view was later confirmed by Davidson's experiment. The concept of matter wave also provides an important theoretical basis for the development of wave mechanics.
Boltzmann entropy equation
1854, clausius, a german scientist, first introduced the concept of entropy, which is a quantity indicating the disorder degree of closed systems. Entropy in Greek means "change". This quantity will not change in the reversible process, but will become larger in the irreversible process. Like a lazy man's room, if no one helps him clean it, the room will only go down in chaos and never become neat. Living things can't do without the law of entropy increase, and they need to absorb negative entropy from the outside to offset the entropy increase. In 1877, Boltzmann expressed the disorder degree of the system with the following relation: S=kLnW, where k is Boltzmann constant and s is the entropy value of the macro system, which is a measure of the disorder degree of molecular movement or arrangement. W is the number of possible microstates. The bigger w is, the more chaotic the system is. From this, we can see the microscopic significance of entropy: entropy is a measure of the disorder of molecular thermal motion in the system. Because of his novel viewpoint, it was not accepted by many famous scholars at first, and Boltzmann paid a huge price for it, which also became an important reason for his personal tragic suicide. The formula S=kLnW was engraved on Boltzmann's tombstone in recognition of his great originality.
Ziolkovsky formula
In the Goddess Chang'e flying to the moon, thousands of families are flying, and human beings have been longing for space for a long time and have made unremitting efforts for it. The key to conquering space is rocket technology.
When it comes to modern rockets, we have to mention tsiolkovsky, the world-recognized pioneer of space theory. It was he who put forward the possibility of using rockets for interstellar navigation and launching satellites. The relationship between rocket structural characteristics and flight speed is established, that is, the famous Tsiolkovsky formula. Where V is the speed increment of the rocket, Ve is the speed 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 has become the key to human conquest of space.
1957, the Soviet Union launched the first artificial satellite, which started the space age. 196 1 year, it sent its first astronaut, Gagarin, and won the first battle of the space race. 1969, the United States sent Armstrong to the moon. Tsiolkovsky focused on ancient rocket technology in China, and asked people to translate military works in the late Ming and early Qing dynasties for reference, especially interested in Wu Beizhi. At that time, there were nearly 30 kinds of military rockets in China. He is fascinated by weapons such as "Dragon Arrow" or "Dragon Out of Water". He had more dreams and inspiration, and soon wrote a book, Dreams of the Earth and the Sky. He has a very incisive famous saying: "The earth is the cradle of mankind, but people can't live in the cradle forever."
