"Mathematics and physics, a magical and wonderful world." Mueller nodded and praised, expressing satisfaction with Shen Qi's choice of depth.

"So what about the auxiliary direction?" Mueller asked again.

According to the practice of the Department of Mathematics of General University, after students choose the main direction, they also need to determine an auxiliary research direction, namely breath.

Of course, Shen Qi's breath also has to choose the research field that Professor Mueller is good at. In addition to mathematics and physics, Professor Mueller also has certain strength in algebraic geometry, number theory, group theory, etc.

Shen Qi immediately made a decision: "I chose algebraic geometry as the auxiliary direction."

"Algebraic geometry, a magical and wonderful world." Mueller nodded and praised, and was also satisfied with Shen Qi's choice of breath.

The old German man has limited English vocabulary, magical and wonderful two English words appear very frequently in his words.

"Mathematics, physics and algebraic geometry are both very profound fields. I admire your courage, young people." The first meeting between Muller and Shen Qi was held in a friendly and harmonious atmosphere.

"I also admire Mr. Muller's extensive knowledge and academic achievements. After all, you are a well-known professor in teaching mathematics, physics and algebraic geometry." Shen Qi said.

"I originally thought you would choose number theory," Mueller said.

Shen Qi replied: "My girlfriend is studying number theory, and I can't steal her job."

"This reason is very good! What a magical and wonderful couple." Professor Muller gave Shen Qi a thumbs up. His personality is not like a German, but more like a French or Italian.

"Do you have a cup of coffee, add sugar?" Muller picked up the coffee pot and invited Shen Qi to have a coffee. The conversation was very enjoyable.

"Just ordinary drinking water is good, thank you." Shen Qi said politely, "I just arrived in the United States and am not very used to drinking coffee."

"Okay, boiled water is healthier." Muller poured Shen Qi a cup of boiled water.

Shen Qi had never seen such a kind and casual German.

Of course, Shen Qi has not seen many Germans. When he was studying at Yan University, he met a German student with a stereotyped poker face, rigorous and self-disciplined.

"Professor Muller, what should I do next?" Shen Qi asked.

Mueller operated the computer to enter Shen Qi's information, and after a while he said: "You need to get 45 credits per semester. When you get 225 credits, you can have a master's degree in Princeton's mathematics department. Then you can choose to study for my PhD, or other tutors' PhD."

“So I need to get enough credits in five semesters.”

"It usually doesn't take that long. The average time to get a master's degree in three to four semesters. The fastest record here is maintained by Tao and Yun. They both took two semesters to get a master's degree and then pursued a doctorate. Shen, you should have heard of Tao and Yun, right?"

"Of course." Shen Qi nodded. Tao was Tao Zhexuan and Yun was his senior brother Yun Wei.

I met my supervisor and chose depth and breath. I needed to complete 225 graduate credits as soon as possible, then pursue a doctorate and get a PhD.

Shen Qi knew very well what he should do next.

The Department of Mathematics recruited a total of 2 graduate students this fall, including 3 from the United States and 9 from 9 different countries around the world.

Princeton’s mathematics department recruits students very strictly. It only recruits such a few graduate students in a season, and Shen Qi, the only one in China, came here to study for graduate school.

All the two math graduate students who enrolled this fall are boys, not a single girl.

Princeton is strict in recruiting students, and even stricter in recruiting girls.

Unexpectedly, the phenomenon of favoring boys over girls would appear in Princeton, which has always claimed to be democratic and equal, and is ranked n. in the United States.

Whether it is an undergraduate, a graduate, or a doctoral student, if she is a girl, she must be particularly outstanding and world-class.

Shen Qi and the graduate students of the mathematics department who entered the same period all have tutors, and they also need to attend classes.

It is just a class, exam, or just doing a topic or writing a paper. Neither of these methods can complete the required 225 graduate credits.

The combination of classes + writing papers is the task that graduate students in the Department of Mathematics will complete, with a maximum of five semesters and a minimum of one semester (in theory).

The fastest record at present is two semesters, maintained by Tao Zhexuan and Yunwei.

The Sberman Hall was designed by the famous Chinese architect I.M. Pei. It is a teaching building where most graduate students in the mathematics department are conducted.

The ongoing teaching in a classroom in Spellman Hall is Algebra Geometry. There were 0 students sitting in the classroom, all of whom were graduate students in the mathematics department.

Shen Qi is also here, this is his first lesson after arriving in Princeton.

Algebraic geometry is Shen Qi's breath, and he chose to listen to this course with direction.

The ten math graduate students in the classroom have different years of admission and seasons.

There is no strict distinction between first and second studies here, both of which are tutoring. Graduates want to listen to what classes they want to listen to and according to their actual needs.

"As we all know, for subalternative surfaces with isolated multi-focal and ordinary multi-focal lines, a -4-substrate surface should play the role of -3 accompanying curves on the sub-curves." The professor of algebraic geometry paused here and knocked on the blackboard, saying: "If we want to keep this double integral limited in the two-dimensional domain of the four-dimensional surface, then what should we do?"

The professor asked questions and students discussed that this was Princeton’s teaching model.

"It is obvious that q is a -4th-order polynomial, and q=0 is a accompanying surface." said a Canadian graduate student.

"I will add that there is a multiple straight line passing through f=0, and at each k-order multiple line with f=0, there is a multiple straight line with at least k-order." An Israeli graduate student added.

"Oh, a beautiful discussion." The professor clapped, he was Romanian.

There was a professor + 0 students in the classroom, and only one of them was American. This is the characteristic of the Mathematics Department of General University, and there were more foreigners than Americans.

Both masters are masters. Shen Qi smiled slightly. Canadians and Israelites were quick-witted, with quick thinking and rigorous logic, and said everything I wanted to say.

"Then I'll add one more sentence." Shen Qi was not willing to be lonely. "The first type of double points is similar to the first type of Abel points. We just need to substitute n=-4."

"Very good!" The Romanian professor praised Shen Qi and asked again: "Child, what's your name?"

"Shen Qi."

After listening to this algebraic geometry class, Shen Qi listened to the analysis of n-s equations again without stopping. This is a course in the field of mathematics and physics.

"Your answer is perfect, what's your name?" asked the professor of n-s equation.

"Shen Qi."

Then, Shen Qi went to listen to the number theory class because there were no other teachings on mathematics, physics and algebraic geometry today.

"May I have your name?"

"Shen Qi."

"May I have your name?"

"Shen Qi."

...

More than a week after the start of school, Shen Qi listened to all the courses that graduate students in the Department of Mathematics could listen to. He listened carefully and actively participated in classroom discussions. He rarely made mistakes, had clear views and reasonable logic, which left a deep impression on the professors of many courses.
