Chapter 140 Although he is strong, I am not weak either!
In the empty classroom, Xu Qingzhou did not plan to continue reading, but took out a manuscript and prepared to think about the tasks for the next semester.
In the first semester, he finished reading almost all the textbooks on applied mathematics, and at least he had a complete mathematical system in his mind, including mathematical analysis, advanced algebra, real analysis, complex analysis, and so on.
I plan to study abstract algebra, geometry and the like slowly.
Especially in the process of proving Cramer's conjecture, it was a bit like breaking through shackles, and mathematical thinking and logic were sublimated.
In the second semester, I can almost resume my previous research and make simultaneous progress in mathematics.
Theoretical physics is an extremely advanced subject, especially in the quantum field. If you want to conduct in-depth research, a particle collider is indispensable, and Kyoto University has this thing anyway.
In fact, there are only a few such machines in the whole country, let alone Peking University.
You have to take it one step at a time.
Xu Qingzhou took a deep breath, picked up a pen, and wrote down what he had researched.
Quantum entanglement super-resolution imaging and quantum stealth measurement
Quantum entanglement enables quantum key distribution (QKD)
Quantum entangled state preparation technology
30 minutes passed.
Xu Qingzhou stared at the manuscript and began to think.
This won't work, the equipment used is too expensive.
Quantum parallel computing?
That didn’t work either. The amount of calculations was too huge. We had consulted several top mathematicians before.
Finally, he picked up a pen and ticked off one of the contents - the compression properties of quantum optical frequency combs.
After he singled out this content, he took out a new piece of manuscript paper and wrote a big title on it.
[The impact of spatial walk-off on the compression properties of quantum optical frequency combs]
Quantum optical frequency combs are of great value in quantum computing, quantum information, and high-precision quantum measurement, and require the use of synchronously pumped optical parametric oscillators and BiBQ crystal materials.
These experimental instruments are available at Kyoto University, but it is more difficult to apply for them.
However, this is probably the easiest experiment to accomplish at this time.
After determining the goal, Xu Qingzhou stopped worrying and started preparing the documents for the experiment.
As before, I have to first come up with a project plan, clarify the research content and objectives, and then write a project application and submit it to the School of Physics.
The project was not very large, and Xu Qingzhou could basically handle it alone. Of course, it would be better if someone could help him, so he could apply for the project first.
Three days passed in a flash. On January 3, the last exam of the School of Mathematics was over, and the holiday was officially over.
Xu Qingzhou took the exam for the School of Mathematics in the morning and the linear algebra exam for the School of Physics in the afternoon.
"carry out an assignment?"
Looking at Xu Qingzhou who came over with the test paper just after 30 minutes, the invigilator was a little surprised. She had been invigilating so many times, and it was normal for students to hand in their papers early in the political class, but these professional courses were different. The questions were difficult and had a great impact on the GPA.
Even after finishing, many people will check it several times.
"Well, I've handed in the paper." Xu Qingzhou nodded slightly, and walked out of the classroom calmly under the puzzled gaze of the invigilator.
In the classroom, Lin Jianxiang and others were already feeling a little numb.
There are even vague signs of his spiritual faith collapsing. Since his first exam, this guy has basically handed in his paper within half an hour. Is he cheating?
Call ~
Lin Jianxiang let out a long breath, thinking to himself, what's wrong with you? Men compete with each other in endurance! No, it's the accuracy. Although he waited until the bell rang before handing in the paper, he was able to ensure that the scores of the first few subjects were above 90 points!
Xu Qingzhou is indeed talented, but he is not weak either. The most important thing is that he attended classes diligently for a whole semester. It is impossible that he is really inferior to Xu Qingzhou who did not attend a single class.
Besides, Xu Qingzhou is good at quantum physics, which is not all about quantum physics. It tests the four major mechanics. Thinking of this, the panic in his heart finally subsided.
After the physics exam was over, Xu Qingzhou did not go to the library but went straight back to the dormitory.
The holiday notice of Peking University has come out. The winter vacation will be from January 1th to February 13th, and they can actually go home after finishing their exams on the 2th.
Xu Zhengyang is leaving school tomorrow, and before that, everyone needs to have a meal together.
In dormitory 101, Xu Zhengyang and the other two were waiting.
Seeing that it was not even 3pm, Xu Zhengyang was extremely surprised. "Huh? Lao Xu, doesn't your exam start at 2pm?"
"Well, I handed in the paper a little early." Xu Qingzhou nodded.
"Awesome! Physics, I haven't even seen you take a few physics classes, and you can hand in your paper early?"
Xu Qingzhou smiled faintly and said, "Actually, I haven't taken many math classes."
"."
After a brief silence, Xu Zhengyang rolled his eyes, put on his headphones and continued playing games, while Kong Xianbo and Zhai Ziqiang also started reading books.
Xu Qingzhou sighed. The truth is always cruel and heartbreaking.
At 5 pm, Xu Qingzhou and his group walked out of the school and held the last dormitory dinner of the first semester in Dormitory 101.
"Boss, please bring us a box of snowflakes first."
As soon as he sat down, Xu Zhengyang shouted.
After they clinked their glasses and finished their drinks, Xu Zhengyang asked, "Lao Xu, Lao Kong, when are you going back?"
Kong Xianbo said: "For me, it should be around the 20th, when the project will just reach the next stage."
Xu Zhengyang nodded slightly, knowing that Kong Xianbo had participated in the project of the senior who was correcting his thesis this semester.
"I'm not sure, most likely after the 20th." Xu Qingzhou really admired Kong Xianbo. He was working on projects, and compiling grades, and at the same time he was doing well in the student union. He had everything in the end.
"Where is your Song Yao?" Kong Xianbo asked.
Xu Qingzhou rolled his eyes and gave up explaining to this guy, "She's going with me."
Song Yao finished her exam on the 10th and planned to read some books at school while she had some free time.
When the roommates drink together, they talk about a wide range of topics, including girls, study, grades, gossip, and national affairs.
Of course, in addition to these, the most discussed issue right now is probably the Mathematical Contest in Modeling, or MCM, which will begin on February 2th, Kyoto time.
This is one of the most popular math competitions for students at the School of Mathematics at Peking University, besides the Xiaguo Mathematical Modeling Competition.
Of course, by August and September, the National Mathematics League for middle schools was actually a small topic, but it was limited to freshmen. After the sophomore year, it no longer received much attention.
Everyone was talking about the question types of previous MCMs, or about the three seniors who would represent Kyoto University this year, saying how many major awards they had won in domestic math competitions, and guessing that there would be no problem with the lineup this time.
Xu Qingzhou was not very concerned about this. Instead of competing, it would be better to do more experiments.
