Great Song

Responding to the Xiaodao's invitation, Shen Kuo boarded the car generously.The carriage traveled all the way west, and after a short while, it left the inner city and stopped in front of a courtyard outside the gate of Changhe.

"Don't you live in the palace?" Shen Kuo looked at the house in front of him and was taken aback.He thought that such a generous person, with the small path of the alchemy room, must be a disciple of some big temple.I didn't expect to live in a house on the edge of the inner city!

"No. I am a priest invited by the Han family, and the alchemy room is in the side courtyard." Zhen Qiong didn't care much, and led Shen Kuo into the door.

After entering the door, Shen Kuo's eyes widened even wider.This house is bigger than I imagined!Facing the street, close to the inner city, and having such an elegant courtyard, you have to be at least Wan Guan to buy it, right?My whole family still lives in a rented house, which is very far from the inner city.Seeing such a yard really made Shen Kuo envious.

But when he entered the alchemy room, these messy thoughts were far behind him.

"Your alchemy stove is really different from others! How come these glass bottles are placed on the table, aren't they afraid of being broken?" Shen Kuo looked at the strange-shaped alchemy stove and the glassware worth millions of dollars on the table in shock. , almost incoherent.What is the history of this trail?For the Patriarch to worship so attentively, he is willing to spend so much money to build such a luxurious alchemy house!

"This alchemy furnace was designed by me, so it is naturally different from other people's. Glassware is also used for alchemy, and it is more accurate to observe with the naked eye." Now Zhen Qiong is really used to these things, and after a few casual introductions, he took them something to use.

"Here, these are the metals used to measure density. Although they are not too pure, they are enough. They can be measured with a measuring cup and a scale." Zhen Qiong took out several identical metal blocks, and weighed them again. Tool of.

"Is this not too pure?" Shen Kuo looked at the obviously refined metals and couldn't help but asked.

"Of course it's not pure enough. This is the only thing I can refine from my little alchemy room. To measure density, the most important thing is to be pure. Even water must be pure water that has been steamed to eliminate interference to a greater extent. .” Regarding these things, Zhen Qiong will not be ambiguous.After all, the density of gold and stone is very helpful for purification, as long as you test it, you will know whether your experiment is successful or not.So he will not be sloppy at all.

Shen Kuo was even more shocked when he heard this.The alchemy he has seen is either grand and transformed, or kept secret. How can there be someone like Zhen Qiong who is so delicate that even the water is pure or not?However, although Shen Kuo's father was transferred since he was a child, he has been to many places, so he also knows the difference in water quality in different places, and sometimes the difference can be as much as a few dollars.If the transpired water vapor is turned into water again, it must be purer than other waters, right?

Heart churning, Shen Kuo looked carefully at the pile of instruments and asked, "Since water is used, how about measuring the ratio of the weight of the overflowing water to the original weight?"

"Exactly." Seeing that he knew everything, Zhen Qiong also became interested, "Do you want to try Shen Guanren?"

How can Shen Kuo refuse?Immediately rolled up his sleeves and buried himself in the tests one by one.

After half an hour.

"The density of tin is really eleven! It's much lower than the number obtained in "Sun Tzu's Mathematical Classics"!" It was just the divisor, Shen Kuo didn't even need to calculate the number, and directly reported the number.After wiping his hands clean again, he wrote down the numbers on a white paper beside him.

In just a short time, he fell in love with this method.Measure one by one and write down the numbers.Looking back at that time, it will be more accurate and convenient than the usual notes!

"Lead is easy to mix in tin. If it is not purified, the specific gravity will be slightly different." Although it is such a simple test, seeing people doing it with great enthusiasm still gives Zhen Qiong a sense of satisfaction as a teacher.He didn't hide it either, and explained with a smile.

"The book really can't be trusted." Shen Kuo sighed, and then looked at the densely packed digital records next to him, "If the density is really accurate. In addition to the fineness, you can easily tell whether it is hollow or not, and you should be able to measure the volume ?”

Irregular shape, always difficult to measure volume.He has been researching the gap accumulation technique for some time, so he can naturally understand it by analogy and easily think of it.

"There are naturally many effects, but if the object to be measured is too thin, it will also involve buoyancy interference, and the measurement will be inaccurate." Zhen Qiong replied bluntly.

"Buoyancy?" It's a new word, but after a little thought, Shen Kuo understood its meaning, isn't it the power of floating? "That's right, even if the iron is thin, it can float on the water, not to mention boats made of wood. I have also heard that the water in some lakes is so weird that people can fall into the lake without sinking. This But it is also related to buoyancy?"

"Well, the salt content of this kind of lake should be too high, which affects the buoyancy of the water. The buoyancy of different solutions is also different, and it is also related to the area in contact with the water. I only know a little about it." This involves the concept of Gewu. It's something, Zhen Qiong is really not good at learning, and dare not talk nonsense.

"It's really amazing. You have to test it carefully later." Shen Kuo sighed, only feeling that what he had learned was still too shallow.However, after sighing, he suddenly realized that for such a long time, there was no "discussion" just listening to the lecture.The old man blushed, and Shen Kuo coughed, "Speaking of which, do you know why things are deflected when they enter the water?"

As he said that, he deliberately put the chopsticks into the measuring cup, and he could really see the slightly deflected scene.

"Because of refraction?" Zhen Qiong swallowed her saliva and replied cautiously.Although he knew some optical principles, it was just an introduction.If the question is too deep, why don't you show your timidity?

Shen Kuo was overjoyed when he heard the words: "Your brother is really smart. I thought that others only knew that light can shine directly, but they didn't know about it. I have several light-transmitting mirrors hidden in my house, and they used this method. The light converges, the light diverges at the convex part, fine grinding, so that the pattern and the mirror surface are slightly concave and convex, so that the light can be twisted and reflected on the wall!"

The sweat on Zhen Qiong's forehead is about to come down, and it's all about refraction. Don't you want to talk about how the light spreads?In Dayi Dynasty's concept of Gewu, this seems to be a problem that cannot be easily mentioned.He doesn't study Gewu, so he can't be dragged into such a completely incomprehensible topic!

Quick to gain wisdom, he chuckled: "Brother Shen's research is really profound. However, the concave and convex of the bronze mirror can have this miraculous effect. If the concave and convex mirror is made of transparent glass, and then observe the things next to it, can it be zoomed in or zoomed out?"

Um?Shen Kuo was startled when he heard the words, and suddenly looked at the measuring cup that was so easy to use.Yes, spotlight and astigmatism, to put it bluntly, just zoom in and out?Nowadays, there are more and more silver mirrors made of glass on the market. Even if the color is not very good, they are still clearer than bronze mirrors.If you use the transparent glass at hand to grind it into a mirror and observe it again, I'm afraid it will be different!And if a set of mirrors can be stacked together, what kind of magical scene will appear?

"This... this is really weird!" Thoughts were running through Shen Kuo's mind, and Shen Kuo's voice trembled a little, and then he became annoyed, "It's a pity that such transparent glass is really rare in the market. I don't know how much it costs to buy a piece... ..."

He is a poor editor, and it is not easy to support a family. He really can't afford it.It's frustrating that a good idea can't be studied!

Seeing that Shen Kuo was hooked by this thought, Zhen Qiong felt relieved, and said with a generous smile: "I always keep a few protective lenses here, why don't I give a set to Brother Shen. If you really grind out a usable mirror, You have to show it to my younger brother!"

He is so rich now, so what is it to send a set of glass mirrors?If the telescope is really made, won't we be able to take a sneak peek at what the emperor looks like when we watch the dragon boat competition next year?

However, as soon as he thought of Jin Mingchi, he immediately thought of someone, and Zhen Qiong's mood immediately sank.I have already agreed not to sign the contract, what else do I want to do with so much!

Gritting his teeth angrily, he raised his smiling face and continued to deal with the problems about refraction and mirrors.After such an "exciting" conversation for another hour, seeing that it was getting late, Shen Kuo reluctantly said goodbye and made an appointment to come back tomorrow.Waiting for tomorrow, be sure to bring a treasured light-transmitting lens, and give it to this like-minded friend!After making up his mind, Shen Kuo put on the glass mirror and left the Han residence happily.

It's really hard to deal with those who learn things!Zhen Qiong let out a long breath, consciously coping with it, she was relieved, and went back into the alchemy room again.

However, what Zhen Qiong didn't know was that this encounter and chat was meticulously told to Han Miao.

"Daoist Zhen bought two taels of gold to rescue that person, took him home and chatted for an afternoon, and gave him a pair of glass mirrors?" Han Miao frowned after hearing Anping's description. "Word.

He was a little happy when he learned that Zhen Qiong went to Rendian for dinner.Feeling that Qiong'er was angry at him for missing the appointment, she wanted to go to Ren's store to have a look.Anyway, Rendian doesn't have tricksters gathering in the corridor during the day, so it's okay to go there.But Han Miao couldn't sit still after hearing all kinds of things behind.

Going to Ren's restaurant for dinner only cost five pennies.He is actually willing to pay [-] sticks to buy gold to save someone from a siege?Not to mention the goggles, Zhen Qiong used the best glass in the kiln, and the mirror surface was particularly smooth.Paint it with mercury and put it in a box and sell it as a silver mirror.This kind of priceless thing is given away casually, which is not in line with Zhen Qiong's usual temperament.You know, he was able to get Zhen Qiong to buy a supper for [-] yuan because of all his scheming!

"What does that Shen surname look like?" Han Miao couldn't help but asked.

"Uh, I'm about 35 or six years old. I'm a little thin, but I have a decent appearance." Shouldn't I check this person's background?Anping was confused, but still answered honestly.

Seeing Anping's expression, Han Miao realized that he had said the wrong thing, and said to his side without changing his face: "Send someone to investigate the origin of Shen Kuo. Where does he live, what is his official rank, and how is his family? Check it out!"

The relatives said yes and retreated.Only then did Han Miao straighten his clothes: "There is nothing to do in the shop, let's go home."

The small things in the store can be left to the subordinates.He had to go back as soon as possible, and he couldn't let Qiong'er be cheated!

The author has something to say: Hey, Han Miao's family lives in the third ring road, and the location is very good, just beside the second ring road.It’s still a two-entry courtyard with a big garden, I’m envious =w=

The reason why Zhen Qiong doesn't like herbalism, and doesn't like Gewuguan, is actually the problem of contempt chain.The Jinshi school belongs to inorganic chemistry, that is, it can despise the herbal school, which learns organically, and the water fire school, which is close to material resources, has become "impure" and pursues different goals, so it can be tolerated but not dealt with.As for the concept of Gewu, many times what the masters of physics talk about, the novice who studies chemistry can’t understand at all=w=Of course, there are also astronomy and mathematics with higher standards. In Qiuzhiyuan, there are court officials compiled by Zhenger Bajing belt =w=

Unfortunately, however, Shen Kuo was a master of astronomy and geography, proficient in mathematics, delved into physics, and was an expert in hydraulic engineering.Qionger: ... let's talk about chemistry QAQ
