Kong Jidao became more and more excited as he spoke. When he went to the second floor of the convenience cafeteria to eat, he listened to him talking about academic affairs. Although he seemed to understand, he was also fascinated. He also felt that it was also a very magical thing to be able to pursue something with all his life.

After stopping, all the students were waiting for Teacher Kong to continue speaking, and for a while he even forgot his deep hatred for Teacher Kong.

After eating a bite of beef pie, Kong Jidao said with a smile: "If you want to talk about this Fermat's theorem, it is much more famous than the Four Colors Theorem. First of all, you have to talk about this Fermat. Who is it! Why do you want to name this conjecture after this person's name?"

"Ferma, a French lawyer and amateur mathematician, has no worse achievements in mathematics than professional mathematicians. He is most interested in logarithmic theory and has contributed to the establishment of modern calculus. He is known as the king of amateur mathematicians."

When Liu Meng heard this, he suddenly felt it was fun. Isn’t Ferma just a person who made such outstanding contributions in the Kingdom of Mathematics, and he can be regarded as a big shot in the soy sauce party.

I still remember when I was bored reading the post, I saw a joke about Ferma, saying that Newton and Leibniz were arguing about a calculus issue. At this time, Ferma came over with a bottle. Since Ferma was also very authoritative in the field of calculus, the two of them asked Ferma to ask him for advice. Both of them were great gods, and Ferma dared not say anything randomly. As a result, he waved his hand and held the bottle and said, "I'm here to make soy sauce."

However, it is really strange in the field of scientific research. In addition to this amateur mathematician, there is also an emperor in the soy sauce party, that is Einstein. He is a patent examiner with serious work. Liu Meng often laughs at himself. He is also a soy sauce party in the math kingdom. He is quite similar to Einstein, and the one who comes into contact with the most is patents.

"Ferma was born on August 17, 1601 in Toulouse, southern France. Although Ferma was not a child prodigy, he was quite smart. What's even more rare is that Ferma worked very hard and learned liberal arts and science well, but his favorite homework was still mathematics."

"In the 17th century, men's most particular profession was to be a lawyer, so it became fashionable for men to learn law. It also made people envious. Following his father's arrangements, Fermat became a lawyer and then maintained this full-time job. Mathematics was always his hobby."

"Ferma never received a specialized mathematics education in her life, and mathematical research was just a hobby. However, in France in the 17th century, no mathematician could match it: he was one of the inventors of analytical geometry; his contribution to the birth of calculus was second only to Newton and Leibniz; the main founder of probability theory, and the person who supported the world of number theory in the 17th century. In addition, Ferma also made important contributions to physics. A mathematical genius, Ferma, was the greatest mathematician in France in the 17th century."

"Ferma's discovery is independent of Descartes' basic principles of analytical geometry. Before 1629, Ferma began to rewrite the lost "Plane Trajectory" by the ancient Greek geometrician Apollonios in the third century BC. In 1630, he wrote only eight pages of the paper "Introduction to Planes and Three-dimensional Trajectory". It is these eight pages that tell Ferma's discovery. Each equation corresponds to a trajectory, which can depict a straight line or curve. In the book, the equations of general straight lines and circles, as well as hyperbolic lines, ellipses, and parabolas are discussed."

"In the 16th and 17th centuries, calculus was the brightest pearl after analytical geometry. As we all know, Newton and Leibniz were the creators of calculus, and before it, at least dozens of scientists had made foundational work for the invention of calculus. But among many pioneers, Fermat is still worth mentioning. He established the method of finding tangents, finding maximum and minimum values, and making significant contributions to calculus."

The students sitting there nodded and began to grit their teeth as they clicked. It turned out that the tangent, extreme value, and fixed points were discovered by this old boy, which made us study hard, but we failed the final exam. Thinking of this, we couldn't help but look at Kong Jidao with hatred, but we were still interested in listening to the following text and seeing how many achievements Fermat, an amateur math man, has made!

"As early as ancient Greece, the relationship between accident and necessity aroused the interest and debate of many philosophers. In the early 16th century, probability theory first studied the problem of dice game opportunities used for gambling, and explored the division of gambling funds. By the 17th century, Fermat considered that there were 16 possible outcomes for four gamblings, except for one ending, that is, four gamblings allowed the opponent to win, the rest of the situation was the first gambler to win, and the probability of making the first gambler win money was obtained."

A classmate sitting there couldn't help asking, "Does Ferma like gambling? I'm studying probability theory. If you win money every time, will Ferma's leg be interrupted by the casino owner?"

Liu Meng also laughed. It was not uncommon for math geniuses to use their knowledge to sweep the gambling city.

In the 1990s, a group of college students from MIT, one of the world's most famous universities, put a lot of their brain power on an extracurricular activity - gambling, especially playing "Blackstart". They used the mathematical principles they mastered to successfully defeat the dealer.

And in the 1990s, they set up an organization called "Blacky One" and went to casinos in Las Vegas regularly and won a lot of gambling money.

The "Blackstick" organization uses a method called card calculation, which allows players to know which cards are beneficial to them when dealers deal. If a smart player knows which cards have been dealt with and which cards are still in the dealer box, they will keep "calculating" and roughly estimate how many "high cards" are left in the dealer box. Once the calculator calculates that the "high cards" are issued in the dealer box, they start to place big bets until the calculator shows that the situation is not good for them.

MIT college students were not the first players to calculate cards. But they used mathematical methods and combined with advanced computer simulation systems to make their tricks perfect. They specially developed several computer programs, formulated the best solutions for special circumstances, and then upgraded program data with the experience they obtained in practice.

Calculating cards is not illegal. It is not considered fraud. However, since casinos are private institutions, they can keep anyone they believe is a threat to the casino, regardless of whether they are illegal or not.

Casinos hire professional security agencies to monitor potential fraud and card calculators. The MIT "Blackstart" organization knew that their behavior was explicitly prohibited by casinos, so they used different pseudonyms to evade security surveillance.

By the late 1990s, the casino security agencies began to target these students from MIT. These agencies were responsible for tracking unpopular players for many casinos in Las Vegas and included photos of these people. Soon, security guards at all casinos in Las Vegas began to recognize members of the Blackjack organization, and they could no longer enter the casino.

Of course. It is said that the bosses of the casino were kind enough to invite these math geniuses to drink coffee and gave them a considerable amount of money to stop going there. They opened casinos to make money. You guys who do math should not be treated as cash machines. If you have no money, just do some things!

Of course, Uncle Sam thought that the best thing is to be a policy of candy and sticks. He gave candy here and waved the sticks in his hand, and said he agreed or not. If he really disagreed, he could only find someone to kill you, the gang of disasters.

Liu Meng himself has a deep mathematical attainments. When he was studying the Sitapan conjecture, he saw such a news. At that time, he thought that if he spent a while to study, he could also build an advanced simulation system for gambling games. It would be easy to win occasionally. If he wanted to use this as a career, he would probably soon become an unpopular person in the casino.

If you are lucky, the casino will give you some money to get out. If you are unlucky, you will probably disappear silently in this world.

Kong Jidao was very dissatisfied with the students who asked this question, and said with anger: "With Mr. Ferma's love for mathematics and noble character, how can he use what he learned to gambling? He would not study probability theory for winning money. All this is just because of interest. Interest is the best teacher, do you understand?"

Liu Meng laughed in his heart. If he went to the United States, he would really want to try his skills in the casino. He disagrees with Teacher Kong's words. He should not raise his personality and become a saint just because Fermat achieved such great achievements. On the contrary, Liu Meng believed that the more vulgar a person, the more he was a person who pursued selfish desires, the stronger the motivation, the more unexpected it could achieve.

The reprimanded student was a girl. She stuck out her tongue and hurriedly buried her head in her meal. Kong Jidao still glared at her fiercely. In his eyes, mathematics was like a pure goddess. This female classmate said this, just like forcing her goddess to go out to pick up customers and make money. It was a great insult to Kong Jidao.

I really didn't expect Teacher Kong to be so angry. Although Liu Meng did not agree, he respected Teacher Kong's purity very much. People of his age mostly maintain a pious attitude towards faith, but young people today are laughing and not taking it seriously.

"Why should the teacher put this anger? This classmate just said casually. Senior Fermat would never blaspheme his love for mathematics so much. Please continue to talk. We are all looking forward to it and wait and see." Liu Meng comforted with a smile.

Kong Jidao was still breathing, and could see that he was really angry, so that his chest was undulating and his anger was striking. After calming down, he continued: "The above achievements were only achieved by Mr. Ferma. What he was really interested in is number theory, respectfully known as the one who supported the number theory of the 17th century. The achievements made by him are really shocking and marveling ghosts and gods. Haha, this is quite similar to you. Logarithmism seems to be born with sensitivity, and solved the Sitapan conjecture at a young age. Maybe you are Ferma of our China."

Liu Meng thought about it and it was really not sure.

"Mr. Fermat has achieved countless results in number theory. Like our common Pythagorean theorem, it can actually be regarded as a special case. The most important thing is to discover the second pair of affinity numbers. People talk about friendship. Interestingly, there is a similar relationship between numbers and numbers. Mathematicians call a pair of numbers with special relationships affinity numbers. As the saying goes, it is difficult to find a soulmate, and finding affinity numbers has made mathematicians rack their brains. Affinity numbers are a small flower in the kingdom of number theory. It has a long history of discovery and beautiful and moving legends."

"Affinity numbers are an ancient number. In the distant ancient times, people discovered that there was a special relationship between certain natural numbers: if the sum of two numbers, the sum of all factors except itself in any one is equal to another number, the two numbers are called a pair of affinity numbers. The first pair of affinity numbers found are 220 and 284, such as the sum of factors 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110 of 284 is 284, and the sum of factors 1, 2, 4, 71, 142 of 284 is 220."

It is said that a disciple of Pythagoras asked him a question: "When I make friends, is there a number function?" Pythagoras replied without hesitation: "Friends are the beautiful figure of your soul, and they should be as close as 220 and 284." He also said, "What is a friend? Just like these two numbers, one is you and the other is me." Later, the Pythagoras School promoted that people talk about friendship, and there is also "neighboring love" between numbers. From then on, 220 and 284 were called "affinity numbers" or "friend numbers" or "blind date numbers".

A classmate couldn't help laughing and said, "So there are people who love each other, aren't they the same as people?"

Kong Jidao glared at him and said, "Everything in the world can be seen as evolved from numbers, and can be described by numbers. If you study hard, you will know how interesting mathematics is, which is much more fun than those boring computer games."

Liu Meng nodded. It is true. Those who like mathematics, if they study to a certain level, they will find the beauty of mathematics. It is really fun. I am afraid that Feima just treats mathematics as a leisurely pastime.

The girl who said the wrong thing before was fascinated by it and couldn't help but ask, "Then is there really only one pair of affinity numbers in natural numbers?" As soon as he asked, he remembered one of the contributions of Fermat's number theory that Kong Jidao had mentioned before was to discover the second pair of affinity numbers, and he couldn't help but stick out his tongue.
