It took a full hour to take a photo.
Lu Zhou dragged his sleepy body back to his dorm. When he opened the door, he saw that Liu Rui was the only one there.
"Where is he? It's not time to eat yet, right? "
Liu Rui, who was doing physics questions, rolled his eyes and said, "He was so shocked by you that he went to study."
Lu Zhou:???
Liu Rui: "Oh yeah, the physics homework is due in the afternoon. You haven't started yet, right?"
"I finished it a long time ago, I already handed it in."
Lu Zhou took out his clothes from his travel bag and spoke casually.
Not to mention this assignment, he had already finished all the major physics assignments for the month.
This was before he went to Beijing. Lu Zhou was a bit embarrassed because he always took time off. He finished all the physics questions in his exercise book and sent them to Professor Lee.
Professor Lee Yong-eun was quite interesting. He glanced at his homework and didn't say if it was correct or not. Instead, he said that he didn't need to hand in his physics homework anymore. Writing these things was a waste of time, so it was better to do something meaningful.
"You finished it?" Liu Rui was shocked. He said, "You didn't even go to class, when did you finish it?"
"Before I went to Beijing, I wrote it while I was doing PowerPoint."
Liu Rui didn't believe him. He took out the question he copied from class and asked, "Then can you teach me?"
"Wait a second, let me take a look."
Lu Zhou put his clothes in the laundry tub on the balcony and went back to his dorm. He stood behind Liu Rui and looked at the question.
[Find the fixed volume specific heat of a mixture of water vapor and hydrogen at room temperature.]
The question was very short and looked simple.
However …
Lu Zhou said, "This question is out of the syllabus, it's normal that you can't solve it."
It was probably a question that Professor Lee Yong-eun assigned in class. He didn't see it when he was writing the exercise book.
Liu Rui:?
Looking at Liu Rui's dumbfounded expression, Lu Zhou smiled and continued.
"At room temperature, diatomic gas molecules and water vapor molecules can be regarded as rigid molecules. Although their covalent bonds still vibrate, the vibrational energy level of most of the molecules will not transition, so they do not contribute to the constant volume heat capacity. Therefore, the conclusion is the same as considering vibration. It might not be mentioned in the textbooks for non-physics majors, but it's mentioned in inorganic chemistry. "
Liu Rui was confused.
Of course, just knowing this was not enough. One also had to know the molar heat capacity of rigid diatomic molecules and the molar heat capacity of water molecules, as well as a series of data that was not given in the question stem.
Mathematics majors did not have chemistry classes, so this question would probably stump many people. To be able to do it, one had to be like Lu Zhou, who had taught himself inorganic chemistry outside of class, or had participated in high school physics competition training.
Professor Lee Yong-eun probably wanted to cultivate the students' ability to learn on their own. After all, in a place like a university, there were only so many class hours. Every teacher was working like a rocket, so there was not much that could be taught in class. A lot of things had to be learned outside of class.
Of course, this also depended on one's own requirements.
If one just wanted to get a graduation certificate, they didn't even have to listen to class. They could just focus on the key points before the exam and brush up their GPA before graduation.
"So, it can be concluded that …"
Lu Zhou picked up a pen and wrote on the draft paper:
The heat capacity of the mixed gas, the fixed volume specific heat of the mixed gas, and the calculation of the above data was very simple. Even a middle school student could do it.
Lu Zhou gave the pen back to Liu Rui and smiled as he said, "This question is quite simple. If you want to calculate the absolute value of the internal energy, you must include the vibration energy of the molecules. However, this kind of question is definitely not going to be on the final exam. Let the physics geniuses worry about it. "
Liu Rui:???
Lu Zhou looked at Liu Rui's muddled expression and asked, "You don't understand? How about I talk about it again … "
"Yes, I do …" Liu Rui nodded with a confused look on his face. "Where did you hear these things from?"
Do we really go to the same university?
Liu Rui began to doubt his life.
Lu Zhou said, "Of course it's from the library."
Liu Rui did not say anything. He quietly began to pack his things.
Lu Zhou asked, "Why are you packing …"
Liu Rui looked up at the ceiling. His eyes were full of sadness as he said, "I feel that my level of knowledge is not enough. From today onwards … I will be in the library every day."
He picked up his backpack and walked out the door without saying a word.
…
Monday afternoon, lecture hall. The audience was packed with people and there were no empty seats.
As the captain, Lu Zhou stood on the stage and was about to give an award speech.
Looking at the dense mass of people below the stage, he knew very well that most of these people were extras urged by the Student Union, the Youth League Committee, and the Green Horse Class.
Everyone was an adult. Who would want to be a celebrity?
As for the freshmen who did not understand the dazzling university life and were fooled by Lu Zhou's words, Lu Zhou did not know if his speech could help them.
However, if they were to work hard for themselves, their university life would be filled with frustration …
There were several media outlets on both sides of the classroom. They were mainly school newspapers and local newspapers. The highest level was probably the Jin Ling City TV station. They were all hired by the university.
When Lu Zhou saw Dean Lu's encouraging look, he thought, "It's not easy to make money." He then cleared his throat and spoke into the microphone.
"Good morning, teachers, leaders, and students!"
"I'm honored to have this opportunity to cooperate with my two teammates to participate in this unprecedented competition. We fought side by side and won the" Higher Education Society Cup ". First of all, on behalf of the national participants, I would like to express my sincerest gratitude to the organizers, sponsors, instructors, and all the people who worked hard for the success of the competition … "
He spoke on stage for more than ten minutes. He talked about the inside and outside of the competition. He talked about the mathematical modeling competition and the learning methods of various subjects. He then talked about the 500,000 yuan annual salary offer and his future plans.
To sum it up in one sentence, 99% chicken soup, 1% method.
After all, it was not Lu Zhou's first time being interviewed. He did not have stage fright and naturally, he kept talking until the end.
Clap clap clap!
There was a thunderous applause in the audience.
Some of them really didn't know, but looking at the freshmen who had copied a page full of notes, it was really quite exciting to see them applaud.
"… Thank you everyone!" Lu Zhou bowed slightly and handed the microphone to Professor Liu. He then walked off the stage.
When Professor Tang saw Lu Zhou walking over, he smiled and said, "Good speech."
Lu Zhou smiled and asked, "Professor Tang, when will the school give me the prize money?"
"Latest by a week. Why are you in such a hurry? The school won't give you less money," said Professor Tang with a smile. He then asked, "So, what have you been researching?"
"Number theory," said Lu Zhou. He thought for a bit and said, "The part about Mersenne primes."
"Mersenne primes? You're still researching that," said Professor Tang with a sigh. His tone was slightly regretful.
Number theory was a magical thing. The threshold was extraordinarily low. How low was it? Many theorems and formulas could even be understood by middle school students. This was why number theory was a "disaster area".
Legend had it that every year, the number of letters written to the Chinese Academy of Sciences about Professor Goldbach's problems could circle the earth. The gatekeeper of the Chinese Academy of Sciences had nine mathematics problems in his hands. If the students could not solve the problems, they would not be allowed to enter.
Therefore, it could be seen that it was far more difficult to achieve results in the field of number theory than it looked on the surface. Not only did it require a solid foundation in mathematics, but it also required extraordinary talent in mathematics.
Reality was cruel. There was no other field or research direction that required talent more than number theory.
If one did not have the talent, it was best not to mess around in number theory. Even if one struggled for a lifetime, they would not necessarily be able to do better than others.
However, even though Professor Tang knew this, he did not dissuade Lu Zhou.
This was because he knew Lu Zhou's personality too well.
Impatient, utilitarian, eager for results.
