Ma Cha thinks in the House of Miracles.

What is the speed of sound? As the name suggests, it is the speed of sound. It's hard to say, sound travels faster in a solid than in a liquid, and it travels faster in a liquid than in a gas, just like a person who eats, and can eat three steamed buns for breakfast, two steamed buns for lunch, and one steamed bun for dinner.

Why does sound have velocity? Sound can travel, of course, it needs a medium, it needs a medium such as water or solid or air, with these mediums, sound can be transmitted, if there is no medium, for example, in a vacuum, sound cannot travel, its speed cannot be talked about, if you have to talk about speed, the speed is zero. From zero to a speed of a few hundred meters a second, what is the result? Obviously, it is the medium.

Taking the iron pipe as an example, the sound is transmitted from one end to the other through the iron pipe, and in this process, the fluctuation of the sound brings the fluctuation of the iron pipe, and the iron pipe transmits the fluctuation from one end to the other, realizing the transmission of sound.

The sound here is transmitted through the iron pipe, but where exactly is it transmitted by the iron pipe? Is it the inner wall of the iron pipe, or is it what? Iron pipes are made of atoms, and in the process of propagating sound, do atoms oscillate due to the oscillation of sound?

If this is possible, then the fluctuations of sound will cause the fluctuations of the atoms inside the object, and the fluctuations of the atoms will cause the fluctuations of the smaller particles inside, and the quantum fluctuations can contribute to the propagation of sound.

Is the world that people face when they get up every day is a vacuum? Obviously not, people breathe air every day, and they have the sound of snorting. Everybody can hear the sound of snorting, and if we're in a vacuum, the sound can't travel through the vacuum, so how can we hear the snoring? How can we hear the snoring? Obviously, we don't live in a vacuum.

There are many kinds of voices that people face every day. The sound of flushing toilets, the sound of spitting, the rumbling of cars, the sound of people talking, all kinds of sounds are mixed in, it is for the noise, so many noisy sounds, the objects of the whole world are vibrated by this sound, to put it in detail. The noisy sound vibrates the atoms in the object, and it also causes the smaller particles in the atoms to vibrate, so that the inside of the object vibrates. Thinking about it this way, it seems that the movement of particles inside many objects on the earth is related to the propagation of various sounds.

If it is really sound that causes the fluctuations of particles inside the object, then. What will happen to the internal vibrations of this particle? If you hit the iron sword with a hammer, you will see a spark coming out, which is an electric spark generated by frictional electricity, and in the same way, when the particles inside the object vibrate rapidly, they will rub against other particles and other things. An electric spark is generated, and this kind of electric spark in the microscopic world inside the object is the electron. Of course, this qiē statement is all a subjective assumption and fantasy of Ma Cha. Whether this is the case or not, Ma Cha does not know.

Particle friction electricity, particle friction in the metal is more frequent, electric sparks and electric sparks can be connected, connected electric sparks can move, the rapid movement of electric sparks, from one place to another, it forms the flow of electricity, which is the reason for metal conduction. What does wood not conduct? Because the vibration of the particles in the wood is slow, it is difficult to connect the electric sparks, and it cannot form the movement of electricity, and the flow of electricity cannot be realized. This is also the content of Ma Cha's fantasies, and when he fantasizes about them, it is as if he has entered the microcosm of objects.

Rapid knocking on the object will cause the internal particles of the object to vibrate, people know that the sound is emitted by the vibration of the object, and the vibration of the particles will also make sound, a large number of quantum vibrations, like a thousand people shouting in unison, so that the object being beaten will make a sound.

If this is the case, our world, sound and quantum are directly related. Further, the sound brings quantum vibration, and this vibration will produce the effect of force, just like a boxer boxing in the ring, the movement of the fist hits the opponent's body, and the opponent is knocked down, this is the power, it is the power that knocks down the opponent, and the quantum vibration will also have a powerful effect, this extremely small guy, movement, its power, can not be underestimated, not inferior to the boxer in the ring.

It is often said that when I visited a famous mountain today, I was indescribably happy. This indescribable is indescribable. Is there anything in the universe that cannot be described? No, every object can be described. Even those so-called "indescribable" objects are actually a description.

People can describe everything, describe what sound is, describe what quantum is, describe what the speed of sound is, describe what quantum force is, and of course, human descriptions will inevitably have errors due to their own limitations. But one way or another, a qiē can be described.

What are the things in the universe? What are the structures of those things? Do those things move? How do they move? Is there a pattern to their motion? What is the relationship between the structure and motion of objects on the earth and the structure and motion of objects in the universe? The universe is very large, and there are too many unknown things in it, so the acquisition of many, many laws is not necessarily the most truthful, so it can be concluded that human beings' understanding of matter and the universe is still rudimentary, and only human beings can continue to explore and become more and more mature, and in the process, human beings will find many errors in their own understanding.

Ma Cha is a person who has a deep kung fu in spells, others see that he can easily defeat the fierce beast in the face of fierce beasts, but they don't know how much sweat he has paid to improve the spell, Ma Cha's thinking about the basic laws of the universe is of great help to Ma Cha's spell cultivation, many of Ma Cha's spells follow certain laws, he continues to practice spells, so that the spell improves, and then he can travel the world, no one urinates.

No matter what knowledge Ma Cha learns, he will draw inspiration from it, and he will use these absorbed nutrients in his spells, so that his spells can be supernatural and unambiguously defeat his opponents.

It's the same with physics, what Ma Cha has learned from physics, will also be integrated into his spells, when he cultivates spells, he integrates the things he absorbs into spells, and his spells have extremely strong magic power, which can destroy many things he wants to destroy, which is true.

Ma Cha's understanding of physics is not to teach the dolls physics in the school, nor to learn what instruments and machines to invent through the study of physics, he understands physics completely for the improvement of spells, and the cultivation of spells is to learn from others' strengths, some people cultivate the Tao and cultivate immortals, and only stare at the witchcraft books in their hands every day, such cultivation is a stupid cultivation.

Ma Cha was still sitting in the miracle room thinking, his consciousness began to flow, his stream of consciousness warm and cheerful.

I am Ma Cha, a magic weapon merchant, a magic weapon merchant who loves spells.

If the sound can cause the vibration of the particles inside the object, when the sound is loud enough and the particles vibrate strongly, the particles will break each other, and the object will be broken. This is supposed to be the reason why the sound shatters the glass.

Since sound can speed up the vibration of particles, if you observe the vibration of particles in a vacuum, will the vibration slow down because there is no interference from sound?

At the other end of the spectrum, is it loud enough to destroy something harder than glass?

Yesterday, I have been thinking about making a flying machine, the problem I have to consider is the sound, when my aircraft flies at about the speed of sound, a shock wave will form in front of the aircraft, this shock wave will bring a great obstacle to the forward movement of the aircraft, this huge resistance, I have to overcome.

I often think that if I make a device on the aircraft, this device can make a certain length of road in front of me into a vacuum, forming a vacuum tunnel, and my aircraft can travel in a vacuum, so that I don't seem to have to worry about any shock waves, I don't have to think about any air resistance, my aircraft will become very fast.

Or I can combine sound with particles, and the energy generated by the vibrations of the particles will propel my aircraft forward, and the aircraft can collect all kinds of sounds during the journey, bringing more intense vibrations to the particles, so that the aircraft can move forward quickly, and this progress is silent.

People can use particles and sound, and for example, people can use ultrasound to remove dirt from the inside of containers such as teapots, to remove calculus from teeth, and to detect the body.

Actually, my aircraft can also use this ultrasound, so I don't have to worry about the cleaning of the aircraft.

Ma Cha looked forward to his future journey in the universe, and with the most sincere feelings, he made himself a cup of coffee, and these days, he always drinks coffee in the Miracle House, where he used to drink tea.

It doesn't matter if the goal in Ma Cha's heart may not be achieved in the near future, or the thinking he made to achieve the goal is wrong, it doesn't matter, people always move forward in making mistakes and correcting mistakes.

Does the movement of particles make sounds? Does sound affect the movement of particles? What is the relationship between sound and particles? What can people do with particles and sound? These questions are all steeped in the coffee of horse tea.

Ma Cha likes this, doing her own things in her own miracle house, thinking about her own things, and this kind of life is so comfortable. It's really comfortable. (To be continued......)
