Chapter 1749
Song Yingxing's position in Chinese history is unique.
Bathed in golden light, step down from the golden platform.
Song Yingxing came to Lu Yan and paid homage to Fang Yan.
Lu Yan valued Song Yingxing very highly.
Quickly help him up

In terms of physics, the newly discovered lost work"On Qi and Air Sound" is an outstanding chapter discussing acoustics.
Song Yingxing studied the occurrence and propagation rules of sound through specific analysis of various sounds, and proposed the concept that sound is transmitted by air.
In terms of chemistry, Song Yingxing analyzed the chemical properties of various non-ferrous metals such as gold, silver, copper, tin, lead and zinc, compared their reactivity, and proposed methods to use the differences between them to separate or test related metals.
When talking about the separation of gold and silver, he pointed out:"For all gold ginseng of pure color and counterfeit sales, only silver can be put in, and there is no hope of the rest. If you want to remove the silver and store gold, break the gold into thin slices and cut them into pieces. The soil is wrapped in mud, and the goose sand melts in the vortex, and the silver is sucked into the soil, allowing the gold to flow out to become the full color. Then add a little lead, and put it into the vortex, and draw out the silver in the soil, which is also there."
‘When talking about the liter of mercury and sulfur to refine vermilion (i.e. mercury sulfide), it was pointed out:"For every pound of mercury, you can get fourteen taels of vermilion, and three liang or five cents of vermilion for each liter of mercury." This increase is partly due to"borrowing sulfur."
The analysis of the separation and combination methods of these metals and compounds shows that Song Yingxing has paid great attention to a large number of chemical reactions. He has realized the interaction between various material components in chemical reactions, and the relationship between various material components before and after chemical reactions. With the idea of "conservation of mass".
Conservation of mass means that in any isolated system, no matter what changes or processes occur, the total mass of matter always remains unchanged.
In the history of science, people's understanding of the conservation of mass went through a long period of time, and was later established by the famous French chemist Lavoisier while studying the combustion process. This was already in the second half of the 18th century. However, Song Yingxing's earliest analysis of the gold and silver separation method and the preparation of mercury sulfide had a glimpse of the profound mystery of this material movement. Although his understanding was not as good as the latter's, he was a hundred years earlier than the latter. for many years

Song Yingxing's status in Lu Yan's heart was no worse than that of Lu Ban and the others.
Tiangong Pavilion now has Lu Ban and Zhang Heng.
Song Yingxing can let him go to other places to engage in agriculture.
Song Yingxing is an all-rounder.
Whether it is agriculture or industry, it can be
""Continue", Lu Yan did not stop after recruiting Song Yingxing. He continued to recruit with all his strength.
As the golden light erupted, a figure walked out. In the upper left corner, there was the name of the other party.
In Chinese history, a famous painter ——Zhang Zeduan.
One volume of"Along the River During Qingming Festival" has become a famous national treasure in Chinese history.
If we evaluate the top ten national treasures of China
《"Along the River During Qingming Festival" is definitely one of them
《"Along the River During the Qingming Festival" is a national treasure among national treasures for China, and is a well-deserved one of the top ten famous paintings passed down from generation to generation.
This painting is a Northern Song Dynasty genre painting. It is the only surviving masterpiece of the Northern Song Dynasty painter Zhang Zeduan and is a national treasure.
Along the River During the Qingming Festival is 24.8 cm wide and 528.7 cm long, ink on silk.
The work is in the form of a long scroll and uses scattered perspective composition to vividly record the urban appearance of Tokyo, the capital of the Northern Song Dynasty, and the living conditions of people from all walks of life at that time. It is a witness to the prosperity of Tokyo, the capital of the Northern Song Dynasty, and a portrayal of the economic situation of the city in the Northern Song Dynasty.
This is unique in the history of Chinese and even world painting. The scroll, which is more than five meters long, depicts a large number of various characters, cattle, mules, donkeys and other livestock, carts, sedan chairs, boats of different sizes, houses, bridges, towers, etc., each with its own characteristics, reflecting the characteristics of Song Dynasty architecture.
It has high historical value and artistic value.
Zhang Zeduan is also an outstanding painter in Chinese history.
I don’t know how much his paintings would be worth if they were kept today.
