Chapter 69 Magical Number Theory

It took an hour to take a photo.

After dragging his sleepy body back to the bedroom, Lu Zhou opened the door and saw that Liu Rui was the only one left.

"Where's the people? It's not time to eat yet?"

Liu Rui, who was buried in the physics problems, didn't lift his head and rolled his eyes: "Those who were hit by you went to self-study."

Lu Zhou: ? ? ?

Liu Rui: "By the way, the physics homework is due in the afternoon. You haven't started writing yet, have you?"

"I finished writing it early, and it's all handed in."

While taking out the clothes in the travel bag, Lu Zhou said casually.

Not to mention this time's homework, he has finished all the major homework for this month.

This is still before going to Beijing. Lu Zhou was a little embarrassed because he always asked for leave every three to five days, so he finished all the physics problems on the exercise book and sent them to Professor Li at one time.

It turned out that Professor Li Rongen was also very interesting. He glanced at his homework and did not say whether he did it right or not. He simply said that he would not have to hand in his physics homework in the future. It was a waste of time to write these things, so it is better to do something meaningful.

"Finished?" Liu Rui was shocked. "You didn't even attend class, when did you write it?"

"Before I went to Beijing, I wrote it when I was doing ppt."

Liu Rui didn't believe it, so he took out the thinking question copied from the class and asked, "Then can you teach me?"

"Wait, I'll take a look."

Putting the changed clothes into the laundry tub on the balcony, Lu Zhou returned to the bedroom, stood behind Liu Rui and glanced at the question.

[Find the solid specific heat of a mixture of water vapor with a mass of M1=3.0X10kg and hydrogen with a mass of M2=3.0X10kg at room temperature. 】

The topic is short and looks simple.

However……

Lu Zhou said: "This question is beyond the outline, you can't figure it out is normal."

It was probably the thinking questions assigned by Professor Li Rongen in class, but he did not see it when he was writing the exercise book.

Liu Rui: ?

Seeing the confused expression on Liu Rui's face, Lu Zhou smiled and continued.

"At room temperature, diatomic gas molecules and water vapor molecules can be regarded as rigid molecules, although in fact their covalent bonds still vibrate, the vibrational energy levels of most molecules do not transition and do not contribute to constant heat capacity. , so the conclusion is the same as considering vibration. It may not be mentioned in the textbook of non-physics majors, but it is mentioned in inorganic chemistry."

Liu Rui: ? ?

Of course, it is not enough to know this. You also need to know the equimolar heat capacity of rigid diatomic molecules and the equimolar heat capacity of water molecules, as well as a series of data not given in the title.

There is no chemistry class for mathematics majors, and this question is estimated to be stumbling for many people. If you can do it, either you have learned inorganic chemistry outside of class like Lu Zhou, or you have participated in high school physics competition training.

Professor Li Rongen posed this question, presumably to cultivate students' extracurricular autonomous learning ability. After all, in a place like a university, there are only so many class hours in a book, and every teacher is driving a rocket. There are not many things that can be taught in class, and many things need to be learned outside of class.

Of course, this still depends on the individual's requirements.

If you just want to get a diploma, you don’t even need to attend classes, you can make a major surprise before the exam, brush your grades before graduation, and you can pass the customs smoothly.

"So, it can be concluded that..."

Lu Zhou picked up the pen and wrote on the scratch paper:

[Cv1=3R, Cv2=5/2R]

[Heat capacity of mixed gas: Ctotal=(M1/u1)Cv1+(M2/u2)Cv2]

[Solid specific heat of mixed gas: c=Ctotal/(M1+M2)]

[From u1=0.018, u2=0.00, R=8.314J/(mol·K)]

[Bring in the above data, get 5.86X10J/(kg·K)]

The calculation is very simple, even for junior high school students, the difficulty is only in the blind spot of knowledge points.

Returning the pen to Liu Rui, Lu Zhou said with a smile: "This question is quite simple. If it is replaced by the calculation of the absolute value of its internal energy, the vibrational energy of the molecule must be included. But this kind of question is the final exam. It's definitely not going to take the test, let's let the top students in the physics school have a headache."

Liu Rui: ? ? ?

Looking at Liu Rui's confused expression, Lu Zhou was stunned and asked, "Don't you understand? Otherwise, I'll talk about it..."

"I understand, I understand..." Liu Rui nodded with a confused expression, "Where did you hear these things?"

Are we really going to the same university?

Liu Rui couldn't help but begin to doubt his life.

Lu Zhou said of course: "Of course it is from the library."

Liu Rui didn't speak, and silently began to pack up.

Lu Zhou was stunned: "What are you doing with your things..."

Liu Rui looked up at the ceiling, his eyes filled with sadness, "I deeply feel that my knowledge level is not enough. From today... I will also go to the library every day."

After speaking, he carried his backpack and walked out the door without saying a word.

...

On Monday afternoon, the amphitheatre was crowded with people, and the seats were full.

As the captain, Lu Zhou stood on the stage, ready to deliver his acceptance speech.

Looking at the crowd of people under the stage, he actually knew very well that most of these people were group performers urged by the student union, the Youth League committee, and the Qingma class.

Everyone is an adult, who would be willing to push people if it's okay?

As for those freshmen who were ignorant of the dazzling college life and all kinds of great people, they were fooled by a word, and they were still holding a small notebook to take notes. Lu Zhou didn't know if his speech could help them.

It's just that if they work hard for their own goals, I am afraid that their college life will be full of frustration...

There are several media outlets on both sides of the classroom, mainly school newspapers and local newspapers. The highest level is probably Jinling City TV Station, all of which are recruited by the school.

Seeing Director Lu's encouraging look towards him, Lu Zhou sighed in his heart "it's not easy to make money", then cleared his throat and said while holding the microphone.

"Teachers, leaders, and classmates, good morning!"

"I am honored to have this opportunity to cooperate with two of my teammates to participate in this unprecedented competition, fight side by side, and won the "Higher Education Club Cup". First of all, please allow me to represent the participating team members from all over the country, to the competition's players The organizers, sponsors, instructors across the country, and all the insightful people who have worked hard for the smooth running of the competition would like to express their most sincere thanks..."

He spoke on the stage for more than ten minutes, from inside the arena to outside the arena, from the experience of mathematical modeling to the learning methods of various subjects, and then from the offer with an annual salary of 500,000 to talk about his future life planning.

In one sentence, ninety-nine percent chicken soup, one percent method.

After all, it was not the first time to be interviewed, and Lu Zhou had no stage fright, so he naturally forced this to the end.

clap clap clap!

There was thunderous applause from the audience.

I really don't know, but watching those freshmen who have copied a page full of small notebooks, the applause is really exciting.

"...Thank you all!" Bowing slightly, Lu Zhou handed the microphone to Teacher Liu and walked down the stage.

In the aisle next to the lecture hall seats, looking at Lu Zhou walking towards this side, Professor Tang smiled and nodded: "That's good."

Lu Zhou smiled, "Professor Tang, when will the school's bonus be distributed?"

"One week at the latest, what are you worried about, how many dollars can the school lose you?" Professor Tang said with a smile, "How about it, what are you studying recently?"

"Number theory," Lu Zhou thought about it and said, "the part about Mersenne primes."

"Mason prime, you are still studying that." Professor Tang sighed, his tone a little regretful.

Number theory is amazing, and the threshold is unusually low. How low is it? Many theorems and formulas can be understood even by junior high school students, and this is also the reason why number theory has become the "hardest hit area for civil sciences".

Legend has it that every year, the letter written by the civil sciences to the Chinese Academy of Sciences about Mr. Goldbach's question can circle the earth when photographed. The janitor of the Institute of Mathematics of the Chinese Academy of Sciences has nine math problems in his hands, and Minke will not let him in if he can't solve the problems.

It can be seen that it is far more difficult to make achievements in the field of number theory than it looks on the surface. Not only do you need to have a solid mathematical foundation, but the most important thing is to have extraordinary mathematical talent.

The reality is so cruel, there is no field or research direction that tests talent more than number theory.

If you don't have that talent, it's best not to toss in number theory, because even if you toss for a lifetime, you won't necessarily achieve more results than others with a "flash of inspiration".

But even knowing this, Professor Tang didn't say anything to dissuade him.

Because he really understands Lu Zhou's temperament too well.

Impatient, utilitarian, eager for success.

When he touches a black nose on the wall of number theory, he will naturally retreat.
