Su Zhe put down the three books in his hands and looked at the time on his phone.

Ten past eight.

He recalled that he watched "Mathematical Analysis I" at around three o'clock in the afternoon and finished it at around six o'clock.

Read a book in three hours and be able to master the knowledge in the book.

As for the side effects, it is probably a large consumption of brain power, and the brain needs to consume a lot of energy.

During the morning examination, a brain CT was performed, and no problems were found, which means there are no bad lesions in his brain.

Thinking of this, I stopped thinking about it.

Looking at "Mathematical Analysis II" on the desk, I turned to the table of contents and started studying.

As time goes by, there are still not many people in the study room on the fourth floor of the library, and there are very few students studying seriously.

But if you listen carefully, you can still hear the whispers of several couples.

Su Zhe didn't care about this and didn't want to listen to the whispers between lovers. He was completely immersed in the book.

After reading "Mathematical Analysis II", he quickly opened "Mathematical Analysis III". When he was halfway through, the broadcast in the study room rang.

"It's 10:50 at night, and there are still ten minutes before the lights are turned off. Those students who haven't left, please leave as soon as possible."

Su Zhe raised his head and scanned around. He was the only one left in the entire study room.

He closed half of "Mathematical Analysis III" and counted the time.

In nearly three hours, I finished reading "Mathematical Analysis II" and half of "Mathematical Analysis III", and my efficiency has improved a lot.

He touched the sweat on his forehead and felt a slight sense of hunger, but everything else was fine.

Take the book and head to the cafeteria.

Although it was eleven o'clock at night, there was another restaurant open in the cafeteria, and he ordered a bowl of some noodles.

After eating some noodles, on the way back to the dormitory, he found that the supermarket was still open. He went to the supermarket and bought a large bag of White Rabbit toffee.

When I returned to the dormitory, I found that Fan Xiaoming had not returned yet.

This shift is really late.

He put away the three borrowed books, washed himself and got ready for bed.

Just after washing up, Fan Xiaoming came back, and the two happened to bump into each other in the living room.

"Xiao Zhe! Why are you so late? Don't tell me that you were driven back by the broadcast from the study room." Fan Xiaoming put down his computer bag and took out his laptop from the bag.

"Yes!" Su Zhe nodded and replied.

"Well, you can go back to the dormitory to read the book. No one will disturb you anyway." Fan Xiaoming opened his laptop.

"The study room has free air conditioning. I also like the atmosphere in the study room." Su Zhe came to Fan Xiaoming's side and looked at the laptop screen.

The screen refreshes data quickly, which is difficult to understand.

"That's true!" Fan Xiaoming stood up and poured himself a cup of tea.

Su Zhe saw Fan Xiaoming sitting on the sofa with tea. He pointed at the laptop screen and asked, "Brother Xiaoming! What are you doing?"

"Analyze the data!" Fan Xiaoming took a sip of hot tea and explained, "As you know, I followed my mentor to study the optical lens of the EUV lithography machine. The manufacturing of this optical lens is very troublesome. The material composition of the optical lens is not I won’t talk about it anymore, let’s talk about the mirror processing of optical lenses, among which..."

Fan Xiaoming spoke very carefully, and Su Zhe listened very carefully.

Currently, Europa’s company Chase is providing optical lenses to BSML, a manufacturer of EUV lithography machines.

Zeiss uses precision machine tool milling to process the lithography machine lens. Subsequently, it undergoes small grinding head polishing, magnetorheological polishing and ion beam polishing to achieve a peak-to-valley surface accuracy of 0.12 nanometers and a surface roughness of 20 picometers.

"Now, there are more advanced CNC optical machining centers, which include stress disk polishing and magnetorheological polishing. After these, optical lenses can achieve a peak-to-valley surface accuracy of 10 nanometers and a surface roughness of 2 nanometers." Fan Xiaoming said with some pride.

"Can we produce this kind of CNC optical machining center independently?" Su Zhe asked.

"Okay!" Fan Xiaoming said with some disappointment, "Now, our problem lies in ion beam polishing. The ion beam polishing equipment manufactured by our R&D center can polish the optical lenses processed by the CNC optical machining center. The optical lenses can only The peak-to-valley surface precision of 1 nanometer and the surface roughness of 200 picometers are an entire order of magnitude worse than those processed by Zeiss."

"The gap is a bit big!" Su Zhe nodded.

"This ion beam polishing technology sounds simple. It uses ion beams to bombard the surface of the optical lens. But the trick is that there is no way to determine the material composition of the ion beam. We can only keep trying." Fan Xiaoming shook his head and said.

Traditional ion beams use inert gases such as argon and nitrogen, but such ion beams cannot meet the accuracy requirements.

"I understand!" Su Zhe thought for a moment and asked, "Is this ion beam polishing technology valuable? How many millions or tens of millions? What kind of knowledge is needed to develop ion beam polishing technology?"

"Of course it's valuable. As long as you come up with ion beam polishing technology, people will buy it even if it sells for not just 100 million, but 1 billion. You know, high-end optical lenses are not only used in high-end lithography machines, but also in photography, measurement, and microscopes. , medical treatment, planetarium and many other high-precision fields." Fan Xiaoming stood up, "As for the knowledge required for research, a PhD level in mathematics and physics is sufficient."

Su Zhe was itching to hear that ion beam polishing technology was so valuable, but he also knew that he did not have the level of a doctor and could not participate for the time being.

He asked with some confusion: "Doctor? Brother Xiaoming, aren't you studying for a master's degree?"

"Well, I am not an ordinary master's degree. Besides, I have published my master's thesis in five SCI papers and completed my graduation defense. In a few months, I will go back to Lingzhou Institute of Technology to attend the master's degree graduation ceremony, and then I will enroll in September. Studying for a Ph.D., to put it bluntly, if I hadn’t been very demanding, I would have graduated with a Ph.D.,” said Fan Xiaoming, patting his chest.

"So what are you doing now?" Su Zhe was a little confused.

"Now I am helping my supervisor with his research. In a few months, I can call him my supervisor. There is no way. My doctoral supervisor is my current supervisor's supervisor, Academician Wang Xiuqi." Fan Xiaoming sat down and said with a smile on his face.

"The doctoral supervisor is actually an academician, and the supervisor's supervisor is your supervisor. This is such a messy relationship... Are you still studying at Lingzhou University of Technology while studying for a Ph.D.?" Su Zhe was a little envious.

"Of course, my doctoral supervisor, Academician Wang Xiuqi, is a professor of Lingzhou University of Technology, dean of the School of Physics, and vice president of Lingzhou University of Technology..." Fan Xiaoming was a little proud, "Xiaozhe! You can consider Lingzhou University of Technology, I admit. There is a slight gap between our school and Tsingta University and Yanda University, but it is not big and it will definitely not bury your talents."

"I will consider it." Su Zhe nodded.

It makes sense that so many number one scholars across the country flock to Tsingta University and Yanda University every year.

Not to mention those who have some but don't, Tsinghua University and Yan'an University are really strong academically. Compared with other universities in China, they are definitely top-notch.

"Xiao Zhe! For geniuses like us, it makes no difference whether we choose Tsinghua University, Yanda University or Lingzhou Institute of Technology. What we need is freedom, freedom to choose a major, freedom in study time, freedom in the bachelor's, master's and doctoral system, etc. ." Fan Xiaoming said half-truthfully.

In his opinion, if Su Zhe chose Lingzhou University of Science and Technology, he might not be able to change his mind.

"Is Lingzhou University of Science and Technology so good? So free?" Su Zhe looked at Fan Xiaoming suspiciously.

Fan Xiaoming coughed and said firmly: "I don't know about Qingdao University or Yanda University. At Lingzhou University of Science and Technology, as long as you are good enough, we will give you whatever you want. Of course, it must be within the framework of the law."

"I'll go back and think about it." Su Zhe remembered the course, "Brother Xiaoming! Can you get the course schedule for Lingzhou University of Technology's science-related majors? It's best to have bachelor's, master's, and doctoral programs."

"Yes! Of course I can! I will send you all the majors in science, including undergraduate, master's and doctoral courses. However, this course was taken four years ago and is not open to the public now." Fan Xiaoming said and started operating on his laptop. .

"Okay! Thank you, Brother Xiaoming." Not long after Su Zhe finished speaking, he received the document sent by Fan Xiaoming.

"You're welcome! You are my sister's student. The stronger you are, the more bragging rights my sister will have. Think about it, you will have major achievements in the future, become an academician, and win the Nobel Prize. My sister It’s not like there’s light on the face.” Fan Xiaoming said with a smile.

"Ah! That's it! Then I'll work hard and win seven or eight Nobel Prizes." Su Zhe said seriously.

"Xiao Zhe! You have such a big heart!"
