520, do those rigid and stubborn mathematicians also understand romance and love? How will they express their love in their hearts?
Let's do a language reading comprehension entitled "The Mathematician's Love", pass and then look later.

Read the short article below to answer questions 1-3.
The love of mathematicians
Li Lingling
(1) The mathematician was given him a nickname by a friend because he was particularly sensitive to numbers and mathematically calculated particularly quickly. Friends say he's a mathematical genius. But the path of love for mathematical geniuses has not been smooth.
(2) Once, he went to a restaurant with a girlfriend who had recently been dating, but quarreled with the waiter at checkout. The meal should have cost 79.80 yuan that day, and if the waiter reported the accurate value, he would not be angry. But the waiter asked him for 80 yuan. He said, no. The waiter said, that's what it says on the bill. Saying that he handed him the handwritten bill, he saw that the bill really said 80 yuan, and said, you have miscalculated, not 80 yuan, it is 79.80 yuan. The waiter said that we were all rounded up here. He said, I don't care how you charge, but you really miscalculated this account. The waiter said, the difference of two dimes is still bad? Mathematicians say, how is it not bad? Can $79.8 and $80 be equated? The waiter said he was stingy, and the mathematician quarreled with her.
(3) The girlfriend was very embarrassed, persuaded him for half a day, and simply left. Broke up with him that night. The girlfriend thinks that he can argue with someone for two dimes, and she can't get by in the future.
(4) Mathematicians are distressed. Friends advised him not to get on fire, saying that he would always meet people who understood him.
(5) Later he really met such a person. She is an accountant, and she also likes to calculate, and she also sees a set of numbers and adds them up to calculate the result. When two people are together, there is always a contest over who counts fast. With her, the mathematician was happy. The mathematician wanted to marry her, but he was yellow again because of a small matter.
(6) It was Valentine's Day, and the mathematician accompanied his girlfriend to go shopping. Seeing a newly opened café offering discounts, I went inside. I asked for two cups of coffee and five small snacks. After eating and going to the checkout, I saw that the checkout line was very long. It turned out that the cashier did not come that day, and the female boss temporarily replaced. She doesn't know much about the scores, and she counts slowly with the help of a calculator. The person who wanted to check out was next to her, and the more she urged her, the more anxious she became, and the more anxious she was, the worse it was. The mathematician came over and said, if you can trust us, we will help you calculate. The landlady looked up at the mathematician and his girlfriend, felt they didn't look like bad people, and agreed.
(7) So, the mathematician helps the female boss to settle the account, the girlfriend helps to verify, and the female boss collects money next to it. After a while, the checkout line disappeared. There was one last guest left. It was this last man's account that caused the mathematician and his girlfriend to disagree. The mathematician calculated that the guest should pay 182 yuan, and the girlfriend said that it was 188 yuan. Let the guests do the math themselves, and the results are the same as those of mathematicians. Finally let the landlady count, and after the landlady finished, look at the mathematician and look at his girlfriend, and say, This gentleman is right. The mathematician girlfriend said, you lie! The landlady said, why should I lie? The result of all three of us is the same, which means that you did miscalculate. The mathian girlfriend said, I'm not wrong, don't believe I'll recalculate for you. The guest was a little upset and said, "Why are you like this?" Miscalculation is not acknowledged. The landlady said, don't be angry, I will collect money according to the results of your calculations. The guest handed him 200 yuan, and the landlady asked him for 18 yuan. The guest walked away with the changed he had retrieved. The mathematician's girlfriend was indignant, she looked at the landlady, then at the mathematician, and left without saying a word. The mathematician ran out to chase his girlfriend. The girlfriend said don't come back to me unless you admit you miscalculated. The mathematician felt that his girlfriend was unreasonable, so he did not look for her again.
(8) The landlady was very grateful to the mathematician for helping her settle the account that day, and when he went to coffee again, he said that he did not want any money. One after the other, the two became friends and later lovers. The landlady is a young single woman, tired of the deceit of the workplace, and resigned to open this café. Mathematicians often come to help the landlady settle accounts, and the landlady admires his numeracy ability. A year later, on Valentine's Day, the two got married.
(9) On the wedding day, the café will receive a 20% discount on all goods. The waiter asked: Are pistachios also discounted? The landlady said, of course, do not fight, how can happiness be discounted? Mathematicians think this is familiar, so they ask, pistachios are not discounted, then how to play last year? The landlady looked at the mathematician and smiled, saying that she hadn't played last year. The last guest bought a plate of pistachios, and you discounted them when you calculated the account, so your girlfriend at the time was right in the account that day. The mathematician was surprised and said, then why do you say she miscalculated? The landlady said, fool, because I have a crush on you! The mathematician was angry and said, how can you do this!
(10) The mathematician could not forgive the landlady and insisted on divorcing her. The landlady didn't understand why mathematicians were so kind to her.
(From Selected Novels)
(1) The following analysis and summary of the relevant content of the novel, the most appropriate two are (20 points)
A． The fourth natural paragraph of the novel seems to be idle writing, but in fact, it carries on from top to bottom, guides the natural development of the storyline, and triggers reading interest.
B． Both the mathematician and the female accountant are helpful, fall in love because of the same hobbies, and eventually break up basically because of personality.
C． The title of the novel is ingenious, both an accurate condensation of the content and a clear sense of ridicule.
D． Through the portraits, words and deeds, psychology and environmental descriptions of the characters, the novel portrays the faces of social beings.
E． Through the ups and downs and gripping plot, the novel inspires readers to think about the true meaning of love.
(2) The seventh natural paragraph of the novel writes that the female boss and the mathematician's girlfriend "looked" twice, trying to analyze the psychology of the characters. (20 minutes)
(3) At the end of the novel, the mathematician miscalculated the account a year ago, how much pistachio did the guest order this time? (60 minutes)
---------------------------------------------------------------------------------
Reading comprehension is over, let's move on to a moment of relaxation.
1. Why is there no mathematics for the Nobel Prize?
Why are there Nobel Prizes in physics, chemistry, biology, economics, and even literature, but there are no Nobel Prizes in mathematics alone?
There is a hot rumor that explains this: the reason why there is no Nobel Prize in mathematics is because Nobel's wife (in some cases, a mistress or fiancée) has had an affair with a famous mathematics professor. Hating Wu and Wu, Nobel did not want to set up a mathematical prize, afraid that he would have to award it to him in the future. While this is a lot of gossip, it's not true.
2. Descartes' poignant love rumors
The most famous love rumor in the mathematical world should be about Descartes, which is also the plot that appeared in the previous "The Hidden Corner" TV series.
That's right, descartes, the founder of analytic geometry who invented the "Cartesian coordinate system" and caused headaches among many high school students.
According to legend, Descartes went to Sweden in his later years and met the beautiful 18-year-old Swedish princess Christina. Christina fell in love with 52-year-old Descartes because she loved math. The king was adamantly opposed to their association and ordered Descartes to be exiled. Descartes ended up in prison, and the mathematical polar coordinate equation appeared in the last love letter to the princess before his death: r =a(1-sinθ). The clever princess solved the heart pattern represented by this equation, also known as the "heart line", and knew that Descartes had always loved him deeply. In the end, the princess never married.
The heart line given on the blackboard in the hidden corner is undoubtedly wrong, in fact the heart line graphic corresponding to r=a(1-sinθ) should be shown in the following figure (here take a=1).
3. The Duel of Galois
If there is a genius in this world, then Galois is definitely one.
A 16-year-old young man who entered college and officially began to study mathematics spent five years creating a new mathematical theory, group theory. It is this set of theories that creates abstract algebra and pushes the study of algebra to a new milestone. However, the value of his research was not recognized until decades after his death. Doesn't it sound a little familiar? Isn't that synonymous with genius?
If there are fools in this world, then Galois is definitely one.
It is said that Galois, who was under the age of 21, fell in love with a woman (there are many opinions about the identity of this woman. Some say they are the daughter of a doctor, some say they are dancers, and some say they are a secret agent). But this woman has another good friend (another said to be the girl's political enemy). The young and vigorous Galois decided to have a duel of "love and honor".
On the other side of the duel was a professional soldier with good marksmanship. Galois knew that he could not escape the fate of death, so the night before the duel, he spent the night writing all night to write all his mathematical ideas, and in the process of writing, he interrupted from time to time, writing "I have no time, I have no time" in the blank space of the paper.
The next morning, in the dueling arena, without any suspense, Galois was punched through the intestines and fell at the age of 21. And this day, it was only 5 years since he began to study mathematics.
Countless posterity regrets it, Galois, why don't you find each other to do a mathematical duel?
4. The one who dropped the Fields Medal for love
As mentioned earlier, Nobel does not have a prize in mathematics. The highest prize in mathematics is the Fields Medal. The Finnish mathematician Alforth was the winner of the Fields Medal.
In 1936, Alforth received the first Fields Medal. After a while, There was World War II, and Alforth actually dropped the medal to raise money for travel expenses in order to see his long-lost wife!
Alforth recalls: "The Fields Medal gave me a very real benefit, when I was allowed to go from Finland to Sweden, I wanted to take a train to see my wife, but I only had 10 yuan on me. I flipped out the Fields Medal and took it to the pawnshop so that I had enough money to pay for the road... I'm sure that's the only Fields Medal that's ever been in a pawnshop..."
This story not only shows that Alforth values love and misses his wife more than personal honors; it also shows that Europeans are very knowledgeable, and pawnshops can accept a pledge of a medal from the mathematical world.
Wait, almost forgot, there is also a stubborn amateur math enthusiast, wrote a book "Math Thinking Lessons for Children", had to juxtapose his wife's name, and make the cover like a marriage certificate.
About author:Xuan (Xuan) Dad, Ph.D. in Computer Science, Chinese Academy of Sciences, is now a professor of computer science at 211 University. He has won the first prize of the National Mathematical Olympiad League in junior high school and high school, the first place in jiangsu division, and the full score of mathematics in the college entrance examination. Usually pay attention to guiding children to mathematical thinking in life, open a public account xuanbamath, and author of the book "Mathematical Thinking Lessons for Children".
