Just when Lin Qianjun reported to the director, Lu Qiujian also came to the president's office with Professor Zhang, and when he saw them come in, the principal got up from behind his desk, pulled them to the sofa and sat down, and after the secretary brought tea, he looked at Lu Qiujian and said, "Oh, I wanted to hire you to stay in school as soon as I graduated, and do research while taking a doctorate!"

Professor Zhang is also quite happy, even if Lu Qiujian is allowed to study for a doctorate at this university, it will be difficult to find a tutor! If anyone is embarrassed to accept him as a student, he must not be laughed at if he spreads the word -- and if you don't look in the mirror, are you qualified to accept a prospective winner of the Fields Medal as a student?

Now that he has a PhD degree from Princeton, his academic qualifications will no longer be an obstacle for Lu Qiujian to stay and teach.

"A 20-year-old Ph.D., that's amazing! I was still an undergraduate at your age!", the president praised with emotion, how old was he when he got his Ph.D.?

"I'm specially awarded, it's not an official doctor!", Lu Qiujian said modestly, "Besides, there are many people who get a doctorate at my age, and Tao Zhexuan got a doctorate from Princeton at about this time, and people really read it!"

"Tao Zhexuan is twenty-one years old when he got a doctorate, more than a year older than you!", Professor Zhang also knows this young genius quite well, "Besides, he entered the university at the age of fourteen, got a bachelor's degree at the age of sixteen, got a master's degree at the age of seventeen, and got a doctorate at the age of twenty-one, but four years later!"

"UCLA can let the twenty-four-year-old Tao Zhexuan be a full professor, can we also make a special case at Beijing Normal University? Well, in fact, it is not a special case, according to the current recruitment regulations, it is normal for a doctor who has returned from a world-class university like Princeton to be hired as a professor!"

If Beijing Normal University wants to become a world-class university, it would not be possible without world-class masters! Lu Qiujian has made such achievements at this age, and how many honors will he create for the school by keeping him at Beijing Normal University? How much attention will it attract? Just thinking about it makes people excited!

"Thank you for the kindness of the principal!", this condition is not unfavorable, but I really can't stay!" "But I feel that my current level is not enough, and I want to go abroad for further study after graduation!"

"You have already obtained your doctorate degree, whether it is the cracking of Poincaré's conjecture or your papers on the Annals of Mathematics and the arXiv website, it is enough to prove that your academic ability has reached the first-class level! Where else do you want to go for further study?", Professor Zhang is a little anxious! Will you go back to Beijing Normal University next time you go out this time?

"I'm afraid I won't choose mathematics anymore if I continue to study, I plan to change majors!", Lu Qiujian said his plan, "I plan to transfer to the physics department." ”

Mathematics is the foundation of all disciplines, but the foundation is the foundation after all, and if you want to apply it, you still have to rely on physics and chemistry; as the saying goes: mathematics is the fire that lights up the lamp of physics; Physics is the lamp that illuminates the path of chemistry; Chemistry is the road, the pit that leads to living things; Creatures are pits, burying science students. Although this sentence is somewhat biased, it also illustrates the relationship between the various disciplines of science.

"Change majors?!", this almost gave Professor Zhang a slap in the face, and he couldn't help but ask repeatedly, "Why should you change departments if you study mathematics well! Since you have a talent in mathematics, you should cherish it, and if you change majors again, you may not have your current achievements!"

"I feel that my research has reached a bottleneck now!, so I want to change the field!", Lu Qiujian came up with the reason for thinking, "and mathematics and physics are also very closely linked, like Professor Edward Witten, whom I met in Princeton, although he is a Fields Medal winner, his main research direction is physics, and I have asked him and Professor Freeman Dyson for letters of recommendation, and they have encouraged me to develop in this field!"

The corner of Professor Zhang's eyes twitched when he heard this, you are only twenty years old and you are talking about the bottleneck! Then what are we people! The principal heard this, and said, "Why don't you do this! After you graduate, you will continue to study mathematics and study physics with the professors of our school from the beginning of the next semester!"

Speaking of this, the principal straightened his back, "Hehe, it's not that I'm boasting, the physics department of our school is second to none in the country, and it can also rank in the top 20 in the world! It's much better than Mizuki University! As long as you are willing to graduate and stay in school, I can find an academician to help you tutor alone!"

In China, I am afraid that only a few top colleges and universities, such as Beijing Normal University, Mizuki University, and China University of Science and Technology, can offer such conditions! If an academician from another school is not allowed to offer himself like a bodhisattva, how can he dare to trouble others for such a trivial matter! But then again, if there is such a student, I am afraid that they will also be happy to tutor him, right?

"At the beginning of the next semester, I plan to prepare well for the report meeting, and then sort out some of my ideas in mathematics! Some basic knowledge of physics will be taught by myself for the time being!", although the physics department of Beijing Normal University is good, there is still a certain gap between it and Europe and the United States, not to mention that according to his plan, after starting physics research, he will use a big guy, and that thing is in Europe.

"As for the choice of schools, I prefer European schools! I am very interested in some of the equipment of their schools and several masters!", Lu Qiujian said apologetically, "So I can only decline the principal's kindness for the time being, but I will try to post as many articles as possible next semester!"

"And I will come back from Europe in two or three years, and there will be no opportunity to cooperate with my alma mater at that time! No matter where I go, I will remember that I am a student trained by Beijing Normal University!", Lu Qiujian bowed respectfully to the president and Professor Zhang.

The two of them looked at each other and sighed regretfully, it seemed that Lu Qiujian's plan to stay in school after graduation was in vain! I hope that he will remember today's words in the future and not forget his alma mater after returning to China.

"Hey, that's all right, let's talk about the report and press conference!", the principal sighed.
