Mathematics is inseparable in our daily life and has become a part of our life. It is everyone's responsibility to learn math well. The following is my collection of magical mathematics manuscripts, welcome to read for reference!
The magical mathematics handwritten newspaper content: the magical e
There is a number, which is an indispensable constant in variable mathematics, a powerful tool to describe various continuous changes in nature, a basic law hidden behind the complexity of nature, and a great mathematician.
Euler's outstanding creation can make the operation of calculus simple and convenient, and it is a number that mathematicians treat kindly. This is:
e=2.7 1828 182845
If you deposit a dollar in the bank, the annual interest rate of the bank is 100% (this is just an example, and it is not necessary to evaluate it with common sense in life). The bank allows the principal and interest to take the middle, and the interest is evenly distributed to each period. For example, if you only save for one month, you will get as much principal and interest as 13/ 12. At this time, if it is not too much trouble, you can choose to withdraw money once every six months and deposit it in the bank with interest. You will get it by the end of this year.
(1+1/2) × (1+1/2) = 2.25 yuan.
If you want to get more money, you can withdraw money three times a year and save it with interest, and you will get it.
( 1+ 1/3)×( 1+ 1/3)×( 1+ 1/3)
If you don't bother, the bank will allow you to run more times and even sit at the cashier's desk. If you divide the year into n times, you will get
( 1+ 1/n)×( 1+ 1/n)×( 1+ 1/n)×( 1+ 1/n)
The product of the above ***n terms. Without thinking too deeply, you will come to the conclusion that the more times you take it, the more money you will get in the end. But how much can I get at most? You can get as much as e=2.7 1828 1828 at most. If you change the interest from 1 to x, you can get as much as the x power of e at most.
This number is an indispensable constant to describe the continuous cumulative changes in nature. The economic growth and decline of nature, the decay of radioactive elements, the thickness of ice and so on are all inseparable from the description of this number.
But e is not a rational number, that is, it cannot be written in the form of division of two integers. In fact, any algebraic operation can't get an integer, which shows that it is beyond.
If this were in ancient Greece, it would be intolerable to have such a number. At that time, there was a school called Pythagoras school, which believed that numbers were the cornerstone of the world and that numbers should be perfect: they could be written in the form of division of two integers. But one of Bi's students pointed out that if the side length of a square is 1, then its diagonal length cannot be expressed as the division of any two integers. Such a figure was considered unreasonable at that time, which triggered the first crisis in the history of mathematics, and students were thrown into the sea and lost their lives.
The magical content of mathematical manuscripts: mathematical jokes
Buy soup
Once upon a time, there was a rich man who never left home. One day, he took some money and some food to the street alone. After shopping for a long time, I felt very hungry, so I ate something, but I felt particularly thirsty and walked into a soup shop. He found a seat and then shouted, "Xiao Er, a bowl of chicken soup." Xiao er quickly brought a bowl of delicious hot chicken soup and said to the local rich man, "There are twelve pieces in each bowl." The local rich man stared at Xiao Er. "I have plenty of money!" "Then he touched his pocket. At this moment, the rich man froze. There is a hole in the bag. He rummaged through it quickly. Fortunately, there are still ten pence left, but how to calculate this account? Suddenly, he swallowed another mouthful until there was still some in the bowl. At this time, Xiao Er also came over and said, "Pay." The local rich threw out ten pence. Xiao er looked worried and said, "I just stopped talking." How can you spend ten pence on a bowl of soup? The local rich man shouted to him again, "I drank all the soup, no, I only drank 12 cents for a bowl of soup, so I'll give you 1 cent!" ""When he said this, the local rich man walked out of the soup shop patting his ass, and Xiao Er still stood there thinking.
What's the difference
Teacher Fang asked Axi in math class, "What's the difference between one-half and one-eighth?" Asi didn't answer. Teacher Fang said, "Think about it. If you had to choose half an orange or eight sixteenth oranges, which one would you choose? " Axi: "I must have half." "Why?" "A lot of orange juice has been squeezed dry when the oranges are divided into one sixteenth, don't you think so, teacher?"
Report the disaster
Once upon a time, a disaster happened in a county. The villagers elected an old man to report the disaster and demanded tax reduction. When the old man came to the county government, the county official asked him, "How much wheat did you get?" The old man replied, "Fifty percent." "What about cotton?" "Thirty percent." "Where is the corn?" "Twenty percent." Hearing this, the county magistrate was furious and said, "You are really bold and unruly, and you come to report the disaster after a bumper harvest!" " The old man quickly said, "I have lived one hundred and eighty years, and I have never encountered such a big disaster year!" " "The county magistrate said," nonsense! How did you live to be 180 years old? " The old man pointed with his finger and said, "The eldest son is 50 years old, the second son is 30 years old, the youngest son is 20 years old, and the old man is 80 years old, a total of 180 years old. It's not bullshit. The county magistrate patted the table and said, "How can there be such an algorithm?" The old man said, "Master, calm down! Didn't you just calculate the harvest? "
