don't call me singer

Chapter 261 Teacher Xiaobai wrote a new song for fear that you won't remember it

In the No. [-] Middle School of Yamanaka County, the large auditorium with a thousand students was full of seats.

In the audience, there were some officials and cadres from Yamanaka County, the principal and teacher of the school, people from the Historical Society who came to invite Gu Xiaobai, and a lot of historians who had left the Northwest History Conference and came here to listen to the lecture .

and many students.

Gu Xiaobai was sitting on the stage, talking about the course "Physics and Music" he had prepared.

At this time, this course has come to an end, Gu Xiaobai said on the stage: "Hopf published a paper "The Bifurcation of Differential Systems from Equilibrium Solutions to Periodic Solutions" in 1942. This paper starts from the more common Study the nonlinear vibration from the angle of view, and obtain the conditions for judging the occurrence of periodic solutions that have nothing to do with the initial conditions, that is, the conditions for the transition to stable periodic motion after the fixed point of the dynamical system loses stability. Later generations call it the Hopf bifurcation , also known as Andronov-Hopf bifurcation, or Poincaré-Andronov-Hopf bifurcation. This kind of bifurcation was not only developed in musical instrument theory, but also later in chemistry, There have been developments in celestial mechanics, radio, etc...”

Speaking of this, Gu Xiaobai smiled and looked at the audience, and said: "Okay, this is all I want to talk about, starting from the "three-point profit and loss method" summarized by Guan Zhong's records, until the first half of the last century, After nearly 3000 years of development, the physical theory of music has finally been basically perfected. The reason why we can hear so much beautiful music is not only because there are countless musicians who have created beautiful music, but also because generations of scientists have Unremitting efforts, the reason why human beings can continue to progress is because they are constantly pursuing the truth..."

Speaking of this, Gu Xiaobai raised his head and looked at the ceiling, as if remembering the achievements of his ancestors: "Now, acoustics and psychoacoustics are still developing, and there are still many unknown knowledge waiting for us to discover , to sum up, students, a bright future is waiting!"

Gu Xiaobai's eyes were shining brightly, as if he had already seen the bright future where he discovered many new laws and formulas.

What a blessing to be a physicist!
happiness!So happy!

After thinking about it for a moment, he looked towards the audience and asked, "Students, have you learned everything I said today?"

Audience: "No-learn-know!"

Gu Xiaobai: "...???"

What?Didn't learn it?I have been talking for so long?You didn't learn it?

He asked again: "Then...do you remember?"

The audience: "I-didn't-remember-remember!"

Gu Xiaobai: “……………!!!!!!”

Gu Xiaobai wanted to hit someone, but you didn't learn it, you didn't remember it, and you answered so confidently!

Believe it or not, I'll go down and beat you!

"Then what have you been doing down here for so long?"

Everyone below replied: "Look - you - ah!"

Gu Xiaobai felt that he was not good at being a teacher at all.

He sat on the stage with his mouth pursed, wanting to cry because of grievance.

Oops, bad, Teacher Xiaobai is unhappy!

Under the stage, a female historian with big waves yelled: "Xiaobai, it's so good! I still want to hear it!"

"Yes, tell me more!"

"I haven't heard enough!"

"Go on go on!"

There was an uproar in the audience.

Then he clapped desperately.

The big wave female historian covered her face and said with emotion: "Oh, I basically didn't understand a single word, why did I finish listening to every word, and still feel that I haven't heard enough?"

Beside her, another young woman who looked like her student had twinkling eyes: "My Xiaobai, even reciting pi sounds good!"

"Yes, Xiaobai, can you recite pi? Recite one..."

"The Three Character Classic is also fine!"

"Thousand Characters!"

Gu Xiaobai: "..."

He raised his head, the king's ceiling, and held back the tears from the corners of his eyes.

Don't cry!

Boys don't cry!

In the audience, Senior Brother Xiao Su didn't know whether to cry or laugh, it turns out that Xiao Bai also has something he is not good at!

For example, he is not at all good at lecturing!
After all, it is difficult for Xiaobai to understand the way of thinking, learning speed, comprehension ability, and knowledge reserve of ordinary people.

He lectures too fast, explains too little, and isn't interesting enough.

Because he himself is too strong, he feels that others are also so strong.

At least...not too weak**.

But in fact, everyone is so weak!

Because you know it and think others know it, this is called the "curse of knowledge".

When Gu Xiaobai really becomes a great professor in the future, he will have to work hard to overcome this shortcoming.

But... it doesn't matter, there are many great scientists who are not good at teaching!

People can accept gifted students!

Brother Xiao Su was thinking about whether to go on stage to comfort Xiao Bai, when he heard someone from the audience say: "For the rest of the time, why not sing a song!"

"Sing! Sing!"

Gu Xiaobai, who was aggrieved and holding back tears on the stage, suddenly his eyes lit up, singing?

Yes, it can be used this way!

"Well... since you don't understand, let's write a song for you!" Gu Xiaobai's eyes sparkled, "As long as you learn to sing this song, you will know it all!"

Everyone in the audience looked bewildered.

Write songs?

Write songs live?
"Wait a minute...Little Xia!" Gu Xiaobai turned around and ran away, and came back with his Yaoqin on his back after a while.

On the stage, he pulled the lectern aside, took out the Yaoqin, stretched out his foot, and with a bang, the Yaoqin was already set up.

A few simple rhythm patterns popped up, and several other people sat beside each other, holding instruments.

"Pa-dong-pa-dong-da, da-dong-da-dong-da..."

The very rhythmic rhythm spread throughout the hall.

"Rap?" Wang Haixia asked.

"Rap." Gu Xiaobai nodded his head.

"Yo, yo~"

"Chunqiu Guanzhong plays five tones, three-point profit and loss 81,

Gongshang Yi conquers the next loss of business, and then gains for the feather and then loses the angle,
With Jiaozhengyu Gongshang, since then, the rhythm has dawned. "

"Come on, everyone sing with me."

In the audience, everyone looked dull.

Want to sing?

Why did it suddenly become teaching singing?
Teacher Xiaobai, are you sure you want to teach us to sing?
"Come on, let's sing together!"

Gu Xiaobai beat the drum with both hands, and everyone couldn't help shaking their heads.

"Yo~yo~ Chuck Nao, pancake fruit is here... no, what horn feather merchant..."

Hey, don't say it, it's quite exciting to sing like this!
After listening to it twice, I can sing it!

magical!

"Yo yo~
The Greek Pythagoras, the arts and sciences are all to blame for him,

Tension density is the same, root fifth and high eighth,
The string length is six to four to three, remember this and don't be afraid.

Everyone in the audience shook their heads and shook their heads: "Yo~ yo~ don't be afraid, don't be afraid!"

Who knows what I'm afraid of!
Anyway, I'm not afraid of anything!
Follow Xiaobai and I sing and play the drums, my waist circumference is three feet five!
"Yo~ yo~
Zhu Zaiyu, the prince of the Ming Dynasty, was the most talented and knowledgeable man in the world.
He is proficient in rhythm, music, dance, and astronomy and physics.

Take the square root of two twelve times, and divide the ratio equally into an innovative method,

This is the twelve equal temperament, and modern pianos rely on it. "

The audience continued to shake their heads.

"La la la la la la ~ who knows what I sing, anyway, the piano depends on it! La la la la la la la ~"

Under the stage, Senior Brother Xiao Su seriously learned to sing, and learned to learn. Hearing all the singing around him, he almost twitched from laughter.

　Can I say that I wrote this song and checked the information for three days, and when I wrote it, it turned out to be a funny song, did my heart collapse...
