Chapter 229: I see you, just like a mayfly sees the sky
"Sound waves? Light waves?"
In the room, the priests who were listening attentively fell into a brief daze.
One of the priests asked doubtfully: "We all understand what the envoy said about water waves, but does this sound also have waves?"
Zhao Duan smiled slightly and said decisively: "Of course there is. In fact, water waves and sound waves are the same."
He then picked up the pen holder in his hand and knocked it on the bookshelf next to him, making a "bang" sound:
"You see, how the sound came out is because the pen collided with the bookshelf and vibrated. If a stone is thrown into a pond, will the water surface also vibrate and make a sound?"
In a world severely lacking in relevant concepts.
When Zhao Duan explains something, he must give up rigor and pursue simplicity.
Sure enough, as soon as these words came out, the priests inside and outside the house suddenly realized and felt that it was very reasonable.
Gongshu Tianyuan nodded his head and said seriously:
"What you said makes sense, just like if the surface of a drum is covered with dust and we hit the drum hard, the dust on the drum's surface will vibrate like water waves."
After a pause, he frowned: "It's just that, for this sound to go from one place to another, does it need any medium to transmit it?"
"Haha, brother Gongshu is meticulous in his observations and metaphors," Zhao Duan praised first, and then said:
"Of course. Well, for example, last time I led the officers and soldiers to arrest the wanted warlock.
Well, Priest Jin Jian was there at that time. The other party believed in the God of Wind. During the fight, he actually took away the Qi from my side and made me suffocate.
At that time, I called out to Priest Jin Jian for help, but found that we could not hear each other's voice. "
outside the room.
A priest excitedly echoed: "Yes, this technique does exist. I have encountered it before, and I couldn't make a sound. But I don't know why."
"So, does it mean that the 'medium' required for the dissemination of sound is Qi? If the Qi is drained, the sound cannot be transmitted."
Everyone was talking about it, and most of the priests here were not craftsman gods.
But don’t delay them from listening to the fun and participating in the discussion.
Zhao Duan smiled and nodded: "You are right. In the same way, the reason why water waves can exist is because water itself is the medium of that wave."
The short and fat young man Gongshu Tianyuan frowned: "What you said is right, but what do you mean by the light waves? Since they are separated from the air, they can still see each other clearly, which means that light does not rely on air to spread, so what does it rely on?" ?”
Oops... I think I got it right. Does the propagation of light need a medium? It seems that there is no need at all...
Well, unless the so-called "ether" concept is brought out... Alas, there is no way, this knowledge has been useless for too many years, and it will be returned to the teacher after work...
Zhao Duan choked and realized that he seemed to have said something wrong.
However, Mr. Zhao is a person who has been tested for a long time. Although he felt guilty in his heart, his face remained calm and composed.
He even showed an expression of admiration and said with emotion:
"Brother Gongshu is indeed a disciple of the Heavenly Master. If you ask me casually, you will find out the key point!"
Gongshu Tianyuan couldn't help but puff up his chest and felt that his face was bright.
Zhao Duan coughed lightly and said seriously: "To clarify this, we must first clarify what light is and what light waves are. In my opinion, everything in the world is composed of a kind of basic particle. Just like a stone, when crushed, it turns out to be particles of dust...
The same is true for water, and the same is true for light...because it is made of particles.
Particles are disturbed by external forces every moment, just like dust moving with the wind. The particles influence each other and become light waves..."
When he said these words, Zhao Duan felt a little guilty.
Because according to the concept of wave-particle duality that he remembered, light itself is both a particle and a probability wave...
But this thing is too abstract, and it also involves the concept of "field"... His expertise is not here, and he only has a superficial understanding of it.
So after some hesitation, I decided to explain it in a more understandable way...
Anyway, it's too abstract, and these people can't understand it at all.
And it’s too fussy and unnecessary.
…
In the small courtyard.
Xu Zhenguan looked at the water curtain with a strange expression, while Zhao Duan talked eloquently.
He couldn't help but turn his head and look at the old Heavenly Master:
"Is everything in the world really made of 'dust'?"
Zhang Yanyi was silent for a moment, noncommittal.
He just said vaguely:
"Haha, how can a mortal figure out the mysteries of heaven and earth? However, what this person said is an interesting hypothesis."
The Heavenly Master seemed calm, but in fact he was equally confused.
According to Taoist theory, heaven and earth are composed of yin and yang, and the five elements... But Zhao Duan went a step further and broke down the qi and the five elements into particles...
If others said it, Zhang Yan would just laugh it off.
After all, there is no shortage of madmen in the world.
But the person who said it was Zhao Duan, who could express extremely insightful opinions when he opened his mouth... The Heavenly Master was a little unsure.
"Let's see how he continues." Zhang Yan said.
Xu Zhendian nodded and turned his attention to the water curtain again.
…
inside the room.
Zhao Duan cleared his throat and said with a smile: "After talking about the appearance of light, we come to the topic of how light travels in the medium. Unfortunately, I cannot give an answer to this question, and I am still exploring it. "
As soon as these words came out, many priests made riotous discussions.
However, Gongshu Tianyuan's small mung bean eyes became brighter and brighter.
He scolded the discussion in a deep voice and said seriously:
"There are countless mysteries that we, the Taoists, do not know. How can we understand all the truths? This is the character that those who seek the Tao should have!"
A group of priests suddenly became ashamed and looked at Zhao Duan with even more respect.
Gongshu Tianyuan's fat face was full of excitement:
"Ignore them, please continue talking! Speak quickly!"
He realized that the next step was to come to the principle of refraction that had troubled him for several days. Zhao Duan smiled and nodded, and said:
"After explaining the above, we should know that the space filled with air everywhere and the suffocating underwater are two media. How many of you have gone to the river to fish?"
Fishing?
Immediately, many priests spoke up and expressed that they had experienced it.
Zhao Duan stood with his hands behind his back and said:
"Experienced fishermen will know that when we stand in the stream and stab the fish swimming in the water with a sharpened stick, we cannot aim. We should point downward to hit the fish. Why do you think that is?"
"this……"
The priests looked at each other, and one of them's eyes lit up: "Could it be that the images reflected by the light are misaligned due to different media?"
"That's right!" Zhao Duan said in approval, "That's the truth."
He gave a series of explanations using diagrams on the small whiteboard, and then said: "This truth is actually no stranger to you. Do you shed tears when you stay up late and are tired and yawn? What will happen at this time? ?”
Gongshu Tianyuan suddenly slapped the table, stood up excitedly, and said: "Clear! Seeing things in the distance will be clearer! I understand! When tears cover my eyes, they are like light entering the stream. I The images you see are like fish swimming in the water..."
At this moment, the descendant of the God of Craftsman looked excited.
The brain is racing.
I felt that the problem that had been bothering me for three days and nights suddenly became clear, and I murmured: "So, grinding a mirror with crystal is equivalent to placing a special piece of water in front of people's eyes at all times... through calculation, adjusting the light beam Reflection..."
"Wait, then why are human eyes like this? Could it be that human eyes are like a pool of water. Just as legs and feet are deformed when injured, human eyes will also be deformed... This leads to unclear vision..."
"Haha, I understand! I understand!"
At this moment, Gongshu Tianyuan kept talking to himself in a low voice.
Staying awake for several days and frantically squeezing his brain cells had already made him emotionally unstable and confused.
This will suddenly break through the shackles, almost dancing.
This made the other priests look at him with suspicion.
"Senior Brother Gongshu is crazy again. The last time he was like this was a few years ago..."
"What do you understand, senior brother? Why do I still not understand it?"
"Where did Zhao Duan learn this skill? How could he speak a few words to make senior brother like this..."
The crowd was buzzing.
Zhao Duan was also greatly surprised, because this fat man's understanding was a bit astonishing.
After all, he had forgotten most of this knowledge, and he only remembered roughly about lenses.
Therefore, what he talks about is mostly conceptual.
And I am not sure whether I am right or not.
But true genius does not require careful teaching.
All he needs to do is give him a direction and a little inspiration, and he will complete everything on his own.
Gongshu Tianyuan, who was inherited by the Craftsman God, was certainly a genius.
It’s just that science is suppressed so much in this era.
At this moment, Zhao Duan's simple conceptual words were like a fog to other priests.
But for Gongshu Tianyuan, it was like a sharp ax that split open the fog in front of his eyes.
Just like a mayfly seeing the blue sky.
"Brother Zhao!"
Gongshu Tianyuan suppressed his smile.
He strode forward, grabbed his hand with both hands, and shook it sincerely, his fat face glowing red:
"Listening to your words will be better than my master!
This is the direction I am pursuing so hard. , I used to rely mostly on magic to create those objects, but what Brother Zhao said today has nothing to do with magic, but the true meaning of the craftsman."
"...Brother Gongshu is serious. What kind of person is the Heavenly Master? I'm just thinking about it on a daily basis, and I've read some scattered books, so I can't believe it. Haha, I can't believe it..."
Zhao Duan smiled stiffly and tried to pull his hand back.
I made a few random remarks on my own, and the effect was far beyond expectations.
Gongshu Tianyuan also knew that he was excited and made a mistake, so he quickly added a few words and then said:
"In short, what Brother Zhao said today is thought-provoking. If you need anything from me in the future, feel free to come find me. Hey, do you need any supplies? For example, this paper skirt can be used by the female family members at home..."
"...No need!"
Zhao Duan took a look at the pile of strange magic weapons with weird functions on the shelf, shook his head and refused, speaking righteously.
"Okay, I've delayed you for a long time, but don't make His Majesty unhappy. Brother Zhao, go and do your work. I still have to digest what you taught me today."
Gongshu Tianyuan looked regretful.
There is a sense of loss that one's own treasure is not appreciated by others.
"In that case, I'll take my leave first." Zhao Duan said with a smile.
For him, gaining this connection is the biggest gain.
…
Russian qing.
Zhao Duan hurried back to the hall where the palace guards gathered.
Then they saw the empress in a gauze robe slowly walking out of the three doors, and the waiters stood up to greet her.
"Your Majesty? Have you finished talking to the Heavenly Master?" Zhao Duan was stunned for a moment.
Xu Zhenguan nodded slightly and stared at him with extremely complex eyes.
He wanted to say something, but he didn't say anything in the end. He walked out and said lightly: "Go back to the palace."
