I love the content of literary manuscripts.

Interesting math 1. Two boys each ride a bicycle, and they start to ride in a straight line from two places 20 miles apart (1 mile or 1.6093 km). At the moment they set off, a fly on the handlebar of one bicycle began to fly straight to another bicycle. As soon as it touched the handlebar of another bicycle, it immediately turned around and flew back. The fly flew back and forth, between the handlebars of two bicycles, until the two bicycles met. If every bicycle runs at a constant speed of 10 miles per hour and flies fly at a constant speed of 15 miles per hour, how many miles will flies fly?

answer

The speed of each bicycle is 10 miles per hour, and the two will meet at the midpoint of the distance of 2O miles after 1 hour. The speed of a fly is 15 miles per hour, so in 1 hour, it always flies 15 miles.

Many people try to solve this problem in a complicated way. They calculate the first distance between the handlebars of two bicycles, then return the distance, and so on, and calculate those shorter and shorter distances. But this will involve the so-called infinite series summation, which is very complicated advanced mathematics. It is said that at a cocktail party, someone asked John? John von neumann (1903 ~ 1957) is one of the greatest mathematicians in the 20th century. ) Put forward this question, he thought for a moment, and then gave the correct answer. The questioner seems a little depressed. He explained that most mathematicians always ignore the simple method to solve this problem and adopt the complex method of summation of infinite series.

Von Neumann had a surprised look on his face. "However, I use the method of summation of infinite series," he explained.

2. A fisherman, wearing a big straw hat, sat in a rowboat and fished in the river. The speed of the river is 3 miles per hour, and so is his rowing boat. "I must row a few miles upstream," he said to himself. "The fish here don't want to take the bait!"

Just as he started rowing upstream, a gust of wind blew his straw hat into the water beside the boat. However, our fisherman didn't notice that his straw hat was lost and rowed upstream. He didn't realize this until he rowed the boat five miles away from the straw hat. So he immediately turned around and rowed downstream, and finally caught up with his straw hat drifting in the water.

In calm water, fishermen always row at a speed of 5 miles per hour. When he rowed upstream or downstream, he kept the speed constant. Of course, this is not his speed relative to the river bank. For example, when he paddles upstream at a speed of 5 miles per hour, the river will drag him downstream at a speed of 3 miles per hour, so his speed relative to the river bank is only 2 miles per hour; When he paddles downstream, his paddle speed will interact with the flow rate of the river, making his speed relative to the river bank 8 miles per hour.

If the fisherman lost his straw hat at 2 pm, when did he get it back?

answer

Because the velocity of the river has the same influence on rowing boats and straw hats, we can completely ignore the velocity of the river when solving this interesting problem. Although the river is flowing and the bank remains motionless, we can imagine that the river is completely static and the bank is moving. As far as rowing boats and straw hats are concerned, this assumption is no different from the above situation.

Since the fisherman rowed five miles after leaving the straw hat, he certainly rowed five miles back to the straw hat. Therefore, compared with rivers, he always paddles 10 miles. The fisherman rowed at a speed of 5 miles per hour relative to the river, so he must have rowed 65,438+00 miles in 2 hours. So he found the straw hat that fell into the water at 4 pm.

This situation is similar to the calculation of the speed and distance of objects on the earth's surface. Although the earth rotates in space, this motion has the same effect on all objects on its surface, so most problems about speed and distance can be completely ignored.

He won British humor.

Tommy: Johnny, how is your little brother? Johnny: He is ill in bed. He hurt himself.

Tommy: That's too bad. How did that happen?

Johnny: We played a game to see who could lean furthest out of the window, and he won.

I have his ears in my pocket.

Ivan came home with a bloody nose. His mother asked, "What happened?"

"A child bit me," Ivan replied.

"Can you recognize him if you see him again?" His mother asked.

"I know where he is," Ivan said. "His ears are in my pocket."

His ear is in my pocket.

Ivan came home with a nosebleed. His mother asked, "What's the matter?"

"A boy bit me," Ivan said.

"Can you recognize him when you see him again?" Mom asked.

"I can recognize him wherever he goes," Ivan said. "His ears are still in my pocket."

Me and the masterpiece I will look for the only companion of my soul in the vast sea of people, and I am lucky to get it; No, my life.

The hourglass of time never stops. No matter how I beg, it will not be attacked by sympathy. Give me some time to calm down and think about what I am pursuing.

The reality is too cruel. Take a step and try again. When I realized that I had lost the courage to try "kissing the flame", I walked into a famous book and eagerly explored all the unknowns. ...

I grew up in "Water Margin" comics, looking at the book world with awe-inspiring friendship, imagining that I am also a chivalrous woman, and Liang Shanquan is a country. So he became a labor committee member with a broom. From time to time, he recruited a few talented people, tried to punish those teenagers who evaded labor, and occasionally used several tricks to "fight tigers with martial arts."

When Yi Zhongtian was popular, I was one of his ten million fans in Qian Qian. Listening to him subvert the Three Kingdoms, rehabilitate Cao, intercede for Zhou Yu, and interpret Zhu Gekongming from a different angle ... The heroic sages with distinctive personality are impressive. Although I hate Mr. Luo Guanzhong's perfidious exaggeration of Cao Mengde from the bottom of my heart, I also lament the hardships of describing this book. I never hide my love for Cao Cao, a lean man who is "in the world". And he is like a "bright lamp", guiding me to the palace of poetry, to the splendor of Xiamen, to the tragicomedy of Wu Gui's longevity …

Reading the Red Chamber is only for memorizing several well-known masterpieces to prepare for the exam. Maybe all those mundane thoughts like rotten oil and sauce are stored in my mind. These words are blood-like articles, such as beautiful colors in the field, which can be passed at a glance. On the second reading of the Red Chamber, I just wanted to see the ups and downs of the four great families in Shi Xue, Jia Lin, but I was unexpectedly attracted by Daiyu's anxiety, Baoyu's stubbornness and Baochai's smoothness, and moved by the ease of the songs of kindness and the sadness of the songs of burying flowers. I just like reading. ...

I don't know when it started, but I was delighted by Confucius' straightforward "Ask his benevolence, I don't know". Injured by what happened to Lian Po; Be impressed by Sean's talent; Trapped in the underground place of boule de suif; I was shocked by Faust's gambling ... in the vast sea of books, I got the "partner" I was pursuing, which is a little comfort in the shadow of reality.

If my siblings ask me the meaning of reading famous books, I can't give them a noble and realistic answer, but when the shackles of reality firmly imprison us, I will still think of dancing in chains, even if I can only read between the lines of that book, I don't want to stop my thoughts. I have been exploring from the beginning of reading, and I have the courage not to be polluted by the world and share it vigorously. The coordinates of life will not stop extending, and I will eventually find a spiritual home above the classics!
