In the past few days, Junxin has been in a busy state, going to class during the day, going to the library to consult materials and writing experimental plans during breaks, and also taking time to calculate and derive the three-dimensional spatial distribution of the five-degree symmetry problem. For a while, the time to talk to Gu Mengxue became very small, although the two often sat opposite each other in the library, but the communication became very rare, and there were only a few words back and forth.

On this day, Junxin and Gu Mengxue finished eating and walked on the way back to the library, because it was neither the exam period nor the weekend, so there were not many people going to the library. So Junxin slowed down, but he was still building a mathematical model in his mind.

"Aren't all of you doing scientific research like this?" Seeing Junxin fall into his own thinking again, Gu Mengxue finally couldn't bear it anymore and asked out loud.

"What... What the? Jun Xin's expression was slightly dazed.

Gu Mengxue walked up to Junxin and said word by word: "Are you mathematicians so unromantic? Isn't it tiring to be boring all day? ”

In fact, Gu Mengxue wanted to say this sentence very early. At the beginning, he met Junxin on the podium in the auditorium, and the two of them spoke at the same time as the representatives of the freshmen, which originally broke the process of the school's opening ceremony, let alone a strict and regular school like Mizuki University? So Gu Mengxue became interested in this record-breaking Junxin at that time.

The next few encounters, in fact, were all coincidental encounters created by Gu Mengxue who deliberately found Junxin and analyzed his work and rest time, but what made her depressed was that Junxin's expression had no other superfluous expressions except for the surprise at the beginning.

However, talented people will always attract people, and talented and maverick people can attract people, so after hearing Wei Donglai's opinion on Junxin, especially when he knew that he had already made results, Gu Mengxue already had a little indescribable feelings for Junxin.

Until this period of getting along, she was very satisfied with all aspects of Junxin, but there was a hidden worry and dissatisfaction in her heart.

The hidden worry is that he knows that Junxin's family background is not good, and he doesn't even know his own background, she grew up in an orphanage, and she doesn't even know the information of her parents. And his family background is very high. This is an obstacle that is difficult to overcome for family members who are particular about their origins and family connections.

What is not satisfied is that Junxin is too immersed in his own mathematical world, so that many times some of his expressions are left empty, which is simply an elm pimple.

"Hehe, are you saying I don't understand romance at all? But did you know that mathematicians are actually the most romantic? "Junxin is not a fool, on the contrary, he has a high IQ, but his EQ is slightly low. But no matter how low the EQ is, I know what Gu Mengxue means.

Gu Mengxue looked at Junxin with a long mouth, Junxin couldn't help laughing, reached out and grabbed Gu Mengxue's hand, led her forward, and said as she walked: "Mengxue, what is your birthday?" ”

"3/2/62! Don't you know? ”

"You're more than nine months older than me! I'm 6/8/63, you should know that! Seeing Gu Mengxue nodded, Junxin continued, "We are actually destined to be together in this life!" Look at the numbers 6232 and 6368, you have me, I have you! ”

"How?"

"Look, you factor the number 6232 and get all its factors, and add up all these factors except itself, and you see what the result is?"

"Let's do the same thing with the number 6368, and you can see what the result is?"

"Hehe, don't forget it, I'll tell you the result. The sum of the factors of 6232 is 6368, and the sum of the factors of 6368 is 6232. ”

"This..."Gu Mengxue was shocked, girls are born with a lot of mysteries, whether it is scientific or not. And Junxin's explanation just hit the softness of his heart. This kind of argument, which is full of mysterious religious overtones, immediately captured Gu Mengxue's heart.

"Mathematicians believe that people should love each other, and numbers should also pay attention to love each other, and shouldn't we pay attention to love each other? Because we are destined for fate! ”

"Letter, I ......" Gu Mengxue held Jun Xin's hand tightly, and her heart was full of emotion.

Jun Xin smiled slightly, for mathematicians, there is a correlation between any number and number, and the birthday between him and Gu Mengxue is just a coincidence. Of course, if this is not the case, Junxin can find a reason and change the algorithm, which can still achieve this effect.

Affinity numbers originated from the Pythagorean school, and the relationship between 220 and 284 was first discovered. In the following hundreds of years, mathematicians completed many calculations through various means, and finally found one affinity number after another. But the secret of affinity is still not known to the public.

"Leaving our exception aside, let's look at what history has been known as the boring romance of mathematicians."

In 1649, on the streets of Stockholm, 52-year-old Descartes met 18-year-old Princess Christine of Sweden. A few days later, he was unexpectedly informed that the king had hired him as the little princess's math teacher. Following the guards who came to inform him to the palace, he met a girl he met on the street. From then on, he became the little princess's math teacher.

The little princess's mathematics advanced by leaps and bounds under the careful guidance of Descartes, who introduced her to a new field of study, the Cartesian coordinate system. The princess's father, the king, was furious when he found out and ordered Descartes to be executed, and after the little princess Christine pleaded, the king exiled her back to France, and the princess Christine was also placed under house arrest by her father.

Descartes fell seriously ill shortly after returning to France, and he wrote letters to the princess every day, but Christine never received Descartes' letter because she was intercepted by the king. Descartes died of exhaustion after sending Christine a thirteenth letter with a short formula: r=a(1-sinθ). The king could not read it, and felt that there was not always a love talk between the two of them, and summoned all the mathematicians of the city to the palace, but none of them could unravel it, and he could not bear to watch his beloved daughter sullen all day, so he handed the letter to Christine, who had been sullen all day.

When the princess saw this, she immediately understood her lover's intentions, and she immediately began to draw the figure of the equation, and when she saw the figure, she was very happy, and she knew that the lover was still in love with her, and it turned out that the shape of the equation was in the shape of a heart. This is also known as the "heart-shaped line".

After the death of the king, Christine ascended the throne and immediately sent people around Europe to look for her sweetheart, but the deceased people left before her, leaving her alone in the world...

It is said that this world-famous alternative love letter is still preserved in the memorial of Descartes in Europe. ”

"There are many more similar examples, and who says mathematicians are boring and don't know romance at all?" Junxin looked at Gu Mengxue's delicate face and smiled, "Mathematicians are the most romantic group of people!" ”
