I just want to be a quiet scholar

Chapter 84 Cultivating hands-on ability
Mu Rong flicked the tuning fork with her fingers.

The Y-shaped tuning fork inserted into the base vibrates rhythmically.

buzzing~ buzzing~
Mu Rong put a finger on her lips and made a gesture of silence, signaling Shen Qi not to speak. The sound wave display was recording the changes in the surrounding sound waves.

Shen Qier listened to the vibrating and humming sound of the tuning fork, and looked at the screen of the sound wave display instrument. A set of continuous wave-shaped images appeared on the screen with periodicity.

Soon, the tuning fork experiment was over.

"Shen Qi, what did you hear?" Mu Rong asked.

Shen Qi replied, "I heard f(t)."

"Any rhythm sound, that is, a sound with periodicity, can be represented by an appropriate combination of harmonics, so what is the coefficient of f(t)?" Mu Rong asked again.

"I don't know." Shen Qi shook his head.

"do not know?"

"I really don't know, the conditions are not enough."

"Actually, Shen Qi, you just said that what you heard was not a sound, but f(t)."

"Of course I know the Fourier series of f(t), but to find the f(t) coefficient..." Shen Qi stared at the screen of the sound wave display, trying to find some useful clues.

"Don't look at the screen, your level is limited at this stage, and it's useless to read it." Mu Rong operated the computer and printer connected to the sound wave display device, beeping, and the printer began to print paper.

"Senior sister, you know that my level is limited, but you still ask me questions that I can't answer?" Shen Qi was speechless.

"You won't know until you ask." Mu Rong said as a matter of course, snickering.

"What about the demeanor of Dr. Yan, Senior Sister?"

"Pleasant demeanor is used to describe a male doctor. I hope you, Shen Qi, can become such a male god one day." Mu Rong spread out the printed drawing on the experimental table, "Shen Qi, look at the drawing again."

There are clear coordinate scales on the printed waveform, which Shen Qi second understands: "The coefficient of a0 is not the amplitude, that is, 0.001? The ω in sinωt is not the frequency, that is, 72000? f(t) Find an integral and divide by Just a T and you're done."

"So Shen Qi, you are still using mathematical thinking to face physics problems instinctively. Of course, physics is inseparable from mathematics, but do you understand what I want to say?" Mu Rong asked straightly.

"Mr. Mu, what do you want to say is a wave in G major? Why is it called a wave in G major? I can understand the wave. The vibration of the tuning fork collides with the nearby air molecules to produce condensation, which causes the air molecules in the previous positions. Another thin space, which is sparse."

"So what our ears receive is the condensation and sparseness of air molecules. This process is represented by the instrument as a set of wave patterns. We can expand f(t) according to the Fourier series and use mathematical physical models to qualitatively and quantitatively explain the sound. The essence and mystery, you can even use it to create sonic weapons of different frequencies. But I still don't quite understand, what role does G major play in this experiment?" Shen Qi answered fluently but still remained doubtful.

Mu Rong didn't answer and asked, "You don't usually listen to music, do you?"

Shen Qi: "Who said that, I like music very much. I often listen to the songs of Dehua, Xueyou, Eason, and Jay."

Mu Rong smiled silently: "Have you heard of Deldera?"

Shen Qi shook his head: "I heard of Dedema."

"Where's Ravel?"

"I prefer Tengger."

"Junior brother, you still have a long way to go to be a handsome male god. You can't be the champion of the competition if you can only read books and do quizzes. Look at the physicists hanging on the walls of this laboratory are the images of middle-aged and elderly uncles. , but they were handsome when they were young, all of them are smart and artistic male gods."

Mu Rong took off her rimless glasses and sighed, wiped the lenses and put them back on: "C major is too moderate and even pale, F major is a tearful smile, only G major is full of energy and makes people extremely excited. You Don't you think physics is the most similar to G major?"

"I don't think so." Shen Qi shook his head, he didn't feel that C major was pale and weak, F major had tears in his laughter, and A, B, C, D, E, F, and G majors sounded the same to him.

"Okay, when I didn't say it." Mu Rong sighed, the female doctor of physics still has a bit of literary heart.

"Do you understand this experiment? It may be practiced in the future." Mu Rong asked, then pulled out the tuning fork from the pedestal.

Shen Qi took the tuning fork and fiddled with it on the pedestal: "Basically I understand, come on, I'll practice it now, Mr. Mu, you guide me... Mr. Mu, where is this thing plugged in, why can't it be plugged in? "

"Shen Qi, why are you so stupid! Why is your practical ability so weak! Put it in the small slot, will you?"

"Don't use brute force. There is a switch. If the experimental equipment is damaged, you will pay Shen Qi. I'll tell you. I've died of poverty recently, and I don't have money for car maintenance. Don't damage it for me."

"Don't drive if you don't have money for maintenance, safety first."

"..."

Under the guidance of Mu Rong, Shen Qi practiced this sound wave experiment again and again. His practical ability is indeed lacking. He has been doing theoretical research all year, and he has not done many experiments.

With the tuning fork in place, the teacher and student stopped speaking after the experiment began, and the conversation between humans would affect the result of the sound wave recording.

Shen Qi didn't have to go to the teaching building for classes, he could spend the whole day in the laboratory.

The other team members arrived at the laboratory in the afternoon, and as soon as they arrived, Shen Qi left.

Shen Qi didn't like to hear the CPhO theory questions that Mu Rong taught to all the team members. He was strong in theory.

After all, Mu Rong has to take care of most of the team members. When she and Shen Qi are alone, they will talk about more in-depth physical theories, and focus on routine routines for all team members.

The main purpose of Shen Qi's consultation with Mu Rong is to expand his knowledge, and CPhO is an incidental link.

There are always a few days every month, Shen Qi will return to the third grade (2) class for inspection.

Gu Xiaodan and Chen Xiaoting are particularly grateful to Shen Qi. After they studied Shen Qi's mathematics experience, their mathematics scores have made great progress and remained stable within a few months.

Gu Xiaodan vowed that he must work harder in the next two or three months. Yanda and Shuimu have no hope of applying for college entrance examinations in the capital's universities. Let's see if there is any hope of being admitted to Beijing Institute of Technology and Beijing Chemical Industry.

"I, Gu Xiaodan, will not accept anyone in my life, so I will accept the big boss Shen Qi. I am not doing anything else in taking the university entrance exam in the capital, but just to help the boss. The most important thing to be a man is to be grateful." Gu Xiao Dan patted his chest and said.

"Traitor, coward!" Chen Xiaoting was still brooding about Gu Xiaodan, and her body trembled slightly.

"Chen Xiaoting, you can say I'm cowardly, but you mustn't doubt my loyalty to Mr. Shen Qi!" Gu Xiaodan slapped the case, very angry.

Chen Xiaoting also stood up and did not give in: "Traitor, coward, no principle!"

Chen Xiaoting has grown to 1 meters, and her chest is a little flatter than her legs.

Gu Xiaodan was only 1 meters tall, and he lost a little in his aura: "Forget it, good men don't fight women."

"Gu Xiaodan, shut up for me, let's go to BIT and BIT, don't brag." Shen Qi scolded Gu Xiaodan and asked Chen Xiaoting, "What about you, where did you take the exam?"

"I..." Chen Xiaoting hesitated, hesitated, and finally said, "I haven't made up my mind yet."

"Xiaoting, don't you have any specialties, do you know how to play the piano or the piano? I remember this time last year, I said to go to the movies, AA, you said you didn't have time to practice the piano, and then we went to the school gate for a quick meal, you bought it Single." Shen Qi asked.

"Yeah, you use imaginary roots, real roots, abelian groups, etc., to drive other shop clerks crazy." Chen Xiaoting couldn't help laughing when she thought of this.

Time flies, looking back on the past, Shen Qi couldn't help laughing: "This is not the point, I will ask you, what kind of violin are you practicing?"

"violin."

"Then you can get extra points in the college entrance examination?"

"No." Chen Xiaoting shook her head and explained: "Art skills are no longer given extra points. The items for extra points in the college entrance examination are provincial outstanding students, three good students, and the top three in the national finals in academic competitions. You should also be able to achieve results in sports. Bonus points, as well as children of martyrs, ethnic minorities... I remember only a few bonus points. So, Shen Qi, if you take the college entrance examination, you can get extra points. "

"Mr. Shen Qi still needs extra points? He's almost 740 in the mock test, and if he adds a dozen or 750 points, heck, [-] is overflowing!" Gu Xiaodan couldn't help but turn his head and said, thinking about it carefully , This is so unfair. The top students with good grades can get extra points. Shen Qi doesn't need extra points at all. It's a waste, it's better to give it to me.
