Know the time of the sky, know the location, understand the phenomenon of the sky, and observe the shift of the five elements.
The behavior of weather forecasting did not arise in modern times. The ancient Qin Tianjian was dedicated to this job, and there were also divisions of duties. , spring, summer, mid-autumn and winter, a total of five people, they deduced the calendar and were in charge of the four seasons. In ancient times, the Yellow Emperor had two people, Da Nao and Rong Cheng, to do this. During the time of Emperor Yao, it was Peng Zu who was doing it.
And when Emperor Shun came, Peng Zu quit this job and became the director of the personnel department.
In addition, in the Qin Tianjian, there are astronomy, stargazing, fortune-telling, northwest wind drinking, membrane mages who master time, bell ringers, and part-time rooster crowing .
Although you are not a major in astronomy, astronomy is something you must learn. If you major in geological exploration, if you only know the location but not the time, it will be very dangerous in many places.
The weather in the uninhabited area of ??Qinghai is not as mild as in the metropolises, coastal areas, and the North China Plain.
When we came near the sundial, the Chifang family had two sundials, and the sundial in the public field was in the middle of the public field. We didn¡¯t talk about it when we came here, and neither did Chongbo and the others. After all, we didn¡¯t move into the public field and saw it from afar After the large weather station under construction, go directly to the farmer's market.
However, the sundial of the Akakata family, near the ancestral land, is placed on an earthen platform, and many wind direction poles have been erected nearby.
Chicken-shaped weathervane, these copper plaques, slowly and lazily, swaying with the wind.
There are also some large tanks below, which store water, and wooden signs are hung on them, which are the signs of rainfall in various periods.
What I want to introduce to them is a strange "apparatus" on the side of the wind direction rod and on the edge of the water tank group.
This instrument is placed on a wide stand and is marked "Rain Measuring Platform".
"This copper vessel is called a rain gauge, and the circle above it is called a water-receiving mouth, and the body of this copper vessel is made of the Shentong Mine near Diyoushi"
Yijun has been forged for a period of time. The smelting and casting of divine copper is time-consuming and requires continuous grinding to cast it well. However, some of the divine copper has the property of "not wearing out", so it is necessary to do the opposite. In short, directly use the wind and fire in the kiln to crack it from the inside.
Just because it won't wear out doesn't mean you won't melt or burst.
The qi in the original copper mine is scattered, and after being cast into a weapon, it will flow its own power according to the state of casting, so the original copper, even the divine copper, is weaker than the formed divine copper weapon when struck .
The original intention of casting is to expel impurities in minerals, and to forge them into weapons with different characteristics according to the experience of the casters.
For example, the reason why iron bars were beaten repeatedly in ancient times was that when they were repeatedly beaten, impurities could be removed, its elemental composition and dense structure could be uniformed, and sometimes its grains could be refined, thereby greatly improving the quality of the material and improving the quality of the casting process. To improve the toughness of the product, let the oxide layer fall off, greatly increasing its strength and hardness.
That's what the so-called "hardened steel" means.
The rain gauge is a product of the Southern Song Dynasty. At that time, it was called "Tianchi basin". Compared with the rain gauge of later generations, the Tianchi basin is of course much simpler.
"When it rains, from the water inlet funnel above, the rainwater will not splash out, but all flow to the bottom, and accumulate slowly in the glass tank for water storage, until the rain stops"
"Based on the amount of water accumulated in it, take it out and weigh it."
The earliest weighing units in ancient China, as well as the era of use, started with the Yi vessel Shang and Tan Heyun. However, after the Warring States period, these two units were directly obliterated by Comrade Qin Shihuang with a big hand, and only a part of the text record exists
Weights and measures are too messy, unify clam!
For the era at that time, these two things are the dross of history
There is no way to find the "one-kilogram weight" now. This thing is covered in a cover under the international convention. The definition of one kilogram comes from it. This weight is obtained through a series of observations. The formulas that I can¡¯t even understand are calculated and formulated. I need to let the cloud calculate it
Sorry, this is so hasty, I choose death.
Therefore, according to later generations and modern society, one catty is equal to five hundred grams, Qin is two three five, Western Han is two five six, then
May I ask how many catties is 30 grams of water?
The answer is 0.06.
Šu Zai asked someone to bring something, which was something that no one in the world had ever seen.
A straight pole, with two plates suspended at both ends, connected by copper chains, and the whole utensil is also made of copper.??.
For some reason, when Yan Zai picked up this thing, the visitors here felt a sense of "sacredness" between heaven and earth.
"What is this?"
Chongbo asked curiously, but he didn't notice the shocked eyes of several Qi refiners!
Yan Zai replied: "This is the most fair thing in the world, and it is also the thing that judges the justice of the world."
"During the time of the Yellow Emperor, there was this thing."
Huang Di, as a black technology expert, made his debut again, not bad! It's this Arrow Stack Fruit Ability User again! Libra, the representative product of weighing instruments, is said to have appeared in the period of the Yellow Emperor, and it was called "weighing" at that time.
At that time, the Yellow Emperor asked Lishou to set up the five quantities of "weighing, douhu, chizhang, libu, ten hundred", which created the weights and measures and the number of acres of land. After the death of the Yellow Emperor, this thing broke down, so his mother lost.
However, there are written records in China, as well as a whole set of weighing instruments that have been truly extolled
That's right, the improver (the real maker) and the unifier of the original weights and measures for the first time was Emperor Shun.
"Shangshu ¡¤ Shundian": "The language of the same law of weights and measures."
The main reason should be that when Comrade Yao Chonghua was doing business in Shouqiu, he was shortchanged twice
In summary, liars are the first driving force of historical development.
And now, Yu Zai is one step ahead of time, and this scale, or "balance", is once again displayed in front of everyone!
"Beimencheng, this is!"
Wuzhuang didn't swear this time, but really turned pale. Looking at Beimencheng, Juliang was also shocked. The snail in his hand stretched out two tentacles and touched Juliang's fingers. It didn't understand why its master would be so surprised.
But Beimen Cheng said: "This is a trade-off!"
Šu Zai smiled: "It is more perfect than the balance. It is said that the Yellow Emperor had this creature, but the effect was not good. Now, I have made a new balance"
Beimen Chengdao: "During the time of the Yellow Emperor, this object was made by Lishou, but at that time, due to some problems, it was finally discarded because it was impossible to accurately measure the weight of the object Your balance is different from that of the Yellow Emperor. What's the difference?"
Yes, the most important thing about weighing instruments is the standard.
This is different from length. The size can be measured with the palm of your fingers. At that time, Ji Liguo measured the water level with a few fingers.
Yan Zai touched his pocket
Please call Šuzai Doraemon.
Ten grains of rice, not too big or too small, were placed on one end of the scale, and the balance, which was originally stable, began to tilt slightly to one side.
