When Zhang Jingtao heard this, he immediately understood why there was an Eve in heaven, and why there was also a summer character in Huaxia.

Also, why is the Jade Emperor in the legendary Heavenly Palace also called Zhang Yu, but unfortunately, Ah He didn't explain Zhang Zi and Jade Zi.

Ah Yu paused for a moment, and only said: "As for the word Yi, I have already told you, in addition to the meaning of a bow of one zhang, it also has the meaning of razing." ”

Ah said this, however, Zhang Jingtao had never heard Ah explain the meaning of this razing.

Moreover, Zhang Jingtao naturally prefers to call Zhang Yu Ah.

And the word 'Hua', Ah still did not explain the details, but fortunately, in this word that Zhang Jingtao used to want to know the answer but always didn't know why, now he is very clear about the meaning of the word 'ten' and the word 'dagger'.

Even, Zhang Jingtao knows that the small arrow and small 'dagger' will be 'lifted' in one direction on the magnet because of its production, so that it has strong magnetism, and because it is often integrated with bamboo and wood, when it is inserted into the wood and put into the water, it has the function of a guide to the sun.

For this reason, the finger of the 'finger' south needle represents the guide technology that the Chinese people have long had, but this kind of Sinan uses an arrow like an iron dagger, not a ridiculous spoon made by those cultural people. Because the dagger in the word 'Hua' definitely represents the clever iron-smelting technology.

Not to mention, the cross in the Chinese character not only has the meaning of making fire, but also has the meaning of a thin needle, which also represents that the fire is heated up and sublimated enough to change the substance.

That's how the meaning of sublimation comes from.

Heating up to enhance the brilliance of the flame, so that the ore undergoes qualitative changes, and the metal is full of brilliance, which is sublimation.

In addition, the cross in 'Hua' represents the shape of a floating compass, and in terms of glyphs, it is pointed to the south from the north to the south.

This completely represents that the Chinese have mastered steel smelting.

From the moment when the Chinese call it Hua.

It can be seen that who created the smelting?

Chinese!

In addition, the Chinese character also represents the origin of arithmetic cross plus sign.

For this reason, when people are grateful to their ancestors and the true civilization of human beings, they will draw a cross and take the land of Tai'a formed by Taihu Lake as the gate of heaven, and call it Amen.

The only thing Zhang Jingtao doesn't understand is that he is alone.

However, after seeing a 10-centimeter cube next to Ah Ah, a glassware called 'cubic liter' by Ah Ah, Zhang Jingtao instantly understood what a single side was.

In today's definition, there is no separate measure, although it is called 1 decimeter, but in fact it is not a unit, because the name 1 decimeter is rarely used.

But in ancient China, there were some of them, called: 1 square meter.

This unit is actually better than the meter, and the decimeter is easy to be confused with the centimeter.

Moreover, in the real Chinese degree method, the centimeter is equal to the modern millimeter, the millimeter is equal to the thickness of the hair, which is the real millimeter, and the unit below the millimeter is the silk meter.

Therefore, the real degree method of Huaxia set by Ah Yu is: 1 square meter = 10 centimeters (modern people mistakenly think it is centimeter) = 100 centimeters (modern people mistakenly think that millimeters) = 1000 mm = 10000 silk meters.

For this reason, the Chinese have always said the word 'silk' together, precisely because they are the two units of the chief of the family.

The filament is divided into nanometers, which is the word "nano", and nanometers are divided into "micrometers", microns, taking the limit of optical microscopes, you can see 2 microns, and microcharacters contain microscope technology, microns, which is the limit of Chinese people's actual measurement of fine objects, and there is no smaller unit.

That is, it is equal to 1 square meter = 100,000 nanometers = 1,000,000 microns.

This is the real nano!

How important is it to know what the size of the real nanometer is?

It is important not to be fooled by the deified microcosm of foreigners, and to know the direction of efforts in materials science, and to produce your own chips!

After seeing this cube rise, Zhang Jingtao was also stunned.

It turns out that the reason why Ah Ah has set a very detailed and precise degree method, so that he can make a completely accurate one-meter long sword, is because Ah Ah uses the diameter of the woven silk as the smallest degree method, and has the metal casting technology that can smelt steel, and obtains a fixed degree method reference.

That is to say, the scale that really takes silk as the size base is called: silk rice.

And not modern silk rice.

In this cubic liter, half of the water was sealed by Ah Ha to observe the temperature change.

Yes, not with mercury, but with a very simple standard carrier: water.

Many people don't know what the ancients would use as a carrier for some scientific research, in fact, it is very simple, of course, the easiest water to obtain.

Water is the most suitable medium in the world.

So, if the expansion rate of water is quite high, how to get a delicate temperature difference, it is simpler, of course, is to expand the cross-sectional area of this carrier for measuring weather temperature, instead of using a thin thermometer.

Just like the cubic liter in front of you, it is a cubic glass body of 10 cm * 10 cm * 10 cm, and the cross-sectional area is large enough.

In addition, Ah Ah used colored silk fabrics to cover the glass side, and the silk threads were extended and stretched out on the two wooden boards of the second measurement, so as to expand this ten thousand, so that people could easily follow the silk threads and find the precise scale of the water surface.

Since Ah Hao used the surname Zhang, it was natural to call this method an exaggeration.

That is, the length of the silk thread is extended to the 'big', but in fact, the length of the silk thread used for measurement is only 10 cm.

It is this exaggerated division that will call the square meter also the decimeter.

For this reason, the esoteric meaning of the word loss has also been unraveled, which is nothing more than saying that the reflection contained in the word 'two' can magnify the scene in the reflection, but in fact it has to return to the original point to calculate the meaning.

In other words, in the stroke of 'vertical and horizontal hook', the vertical has a deep meaning, the horizontal hook has an extension and expansion, and the curved hook has a return to the origin.

The word "dragon" means that this animal, which has a mouth and throat as large as the size and can devour, has a long waterline like a water dragon when it swims, but in fact its body is much smaller.

And Ah will define the dragon like this, it contains biological code, which is to tell you that the dragon seems clumsy, especially in winter, but! It swims extremely fast in the summer when it is very active! Fast enough to pull out a long line of water!

This is how the meaning of the word span comes from, because the silk thread is crossed to the plank.

After the silk thread is completed, it is necessary to complete the action of opening.

This is exaggeration.

Exaggeration, as the word, records this real measurement method, which can obviously be used in many fields of measurement.
