What's even more subtle is that the speed of light is so fast, but Ah He knows by observing the sun that no matter how fast the speed of light is, it is also a process from darkness to light.

For some reason, she somehow learned the principle of the turntable, so she thought that she could use a toothed turntable to measure the speed of light.

Therefore, the vertical above the light and the horizontal combination below represent the turntable with gears, and this vertical also represents the light from the vertical, but below the light word, there is no corresponding vertical, that is, when the vertical comes over, it is blocked by the vertical itself representing the gear.

It is conceivable that by shaking this gear, the speed of light can be obtained, as long as the gear is made large enough and shaken fast enough.

Ah's ability to observe light accurately, and whimsical ideas, are all in this word!

This is also because Ah Ah likes light too much since she shoots the sun Guanyin, so she will understand these.

The subtlety of Chinese civilization can be seen.

On the contrary, it can also be seen that light, the word, inherits optical civilization.

When you teach this word, you can teach a lot of optical principles by the way.

Huaxia 3000 Avenue is so powerful!

The principle of optical fiber, a high-end material in later generations, still comes from this word "light".

Zhang Jingtao was also amazed, unexpectedly, this word 'light' contained so much knowledge.

Then, what made Zhang Jingtao even more shocked was that the promise he promised the civet could be fulfilled directly.

Because Ah Ah took out a mirror.

This mirror is already very bright and clear, because when the liquid glass is relatively turbid, he naturally thinks that adding some alkali can make the liquid cleaner, so he added alkali when firing.

It is conceivable that after the glass is fused with alkali, it really becomes very clear, and then, Ah He saw that the glass was slightly reflective, and wanted to make the reflection clear, and because the reflection of the metal sword was excellent, she thought of a way to 'dye' the metal color on the glass, and this was not difficult for her to do.

The principle is very simple, after Ah found that silver and tin are easier to melt, he put the finished glass in the fire cellar, put silver beads and tin beads on it, the temperature is not too high, after these metals are melted, because they contain tin, the fluidity is excellent, and a glass mirror is made.

At this moment, all the women knelt down, even the children, who were screaming from them, and they all knelt down.

Not even mentioning them, even Zhang Jingtao knelt down.

With the crowd shouting and bowing.

You know, he understands the achievements of civilization, so he has a lot of insight, but if he wants to create civilization?

I'm afraid he doesn't even know how the earth turns!

Hello, for Zhang Jingtao, she is also a fairy!

In particular, it's only been half a year, and Grande's use of the fire cellar has developed to such an amazing point, how can it not be shocking?

Like the speed measurement method of the light, most modern people are not very clear.

For this reason, Yinuo and Cai, who were also listening to the class, and even Huoyu and Manniang and others all knelt down and shouted.

Ah He couldn't help but hook the corners of his mouth a little, smiled triumphantly, and waited for everyone to get up before he said: "I just want to tell you that after knowing the light and the mirror, we have another number: two!" ”

The children were all talking.

After a while, he said: "The word 'two', composed of a small plane and a large plane, represents the mirror image, I plan to make it pronounce the same as my son's son, and the child is the tail attached to the body, that is, the continuation of the body, our descendants, and the meaning of our replica." Thus, two, is the meaning of two things that are the same or similar. ”

Then, she also said e

The meaning of this pronunciation is the fire produced by the spinning potato e after the short wooden stick is burned

underneath, there will be a shadow meaning.

Zhang Jingtao immediately understood when he heard it, the reason why the word 'and' has a turning meaning is that the shadow '丿' under the 'one' on the water surface can be divided into many kinds, several vertical lengths are different, it can be like this, it can also be that, but their essence is shadow, but it can derive many different phenomena and even achieve different results.

For this reason, I use two tones too.

There are also ears, and the two verticals under the 'one', just like the verticals in the 'and', have the meaning of different lengths and shortnesses, which means that the water surface is listed differently, and the 'one mention' is fed back to the brain, producing an illusion mirror 'two'.

For this reason, the word ear refers to the understanding of biology, and refers to the structure of the ear.

The ear, it is through the periosteum that absorbs sound vibrations and transmits them to the spiral-shaped cochlea, causing the vibration of different shades of fluid in the cochlea and feeding back to the brain, so that people have an intuitive understanding of sound.

Sure enough, it is: Tao is born one, and life is two.

Zhang Jingtao was extremely curious about this, and wanted to know how the third came about.

Ah didn't disappoint him, and had already written the word 'three' on the board.

It's just that when I want to explain this word, Ah He said that he would have to wait until the evening.

Ah Yu only said: "Fu Xi, you know that the surface of the water is concave, right?" ”

Zhang Jingtao said: "I know." ”

"That's why I pronounced the concave one, using a for lake water and an o for a circle basin, and called it ao, because you can clearly see this from a basin of water." In addition, I separate the light from day to day, and call it it

, you know, this

, it comes from the sound of the slave and the sound, and it is said that it is used in the light of the day, that is, the side where the sun sets, to divide a day, so

In my opinion, it can mean the meaning of dividation, partition, door, that side, and so on. ”

Zhang Jingtao said: "I know, so I want to sound, the reason why I use yi."

Such a pronunciation, that is, the sun's rays i into the lake form the sum of the day's light thought after y, used

Meaning of division. ”

Ah He said approvingly: "Yes, in addition, I take the silk sound of the silkworm baby shaking his head and weaving cocoons, as a trajectory of shaking or sliding back and forth, which also represents silk, but also represents that the silkworm cocoon is drawn and the silk is diverged, and so on, you also think of it, right?" ”

Zhang Jingtao said: "I can think of it." ”

Ah Yu smiled and said: "Three, that is, one and two overlap, that is, the Tao is born one, one life is two, these three, but I deliberately combined the two words, not the word 'two', and the physical mirror or the water surface and the hot shaking of the ground brought by the image to correspond to the text, this combination method, can be described as three to all things, then, guess what, why I put the pronunciation of this word, set sa."

This? ”

Zhang Jingtao's mind was spinning, but he couldn't think of it.

Third, the dispersion, the umbrella, the tong, the rest, all are fake words, those fake words are the Confucian culture that disturbs the only civilization of mankind, not the civilization of the Chinese people.

But why is the sound 'scattered' used?

Zhang Jingtao couldn't help but say: "Why? ”

Ah He smiled and said, "Come back to school in the evening, I'll tell you." ”
