First Minister of Ming Dynasty Chapter 686

Zhang Ximeng came to Jimin Academy, naturally not to accept flowers and applause. He brought many newly compiled lecture notes and some experimental equipment, including many glass products, bottles and jars, and two quite large telescopes. .

These things made Liu Sanwu a little dizzy.

"Zhang Xiang, this, this is your latest achievement?"

Zhang Ximeng laughed, "It's not mine, but the ingenuity of countless people. Take this telescope as an example, it was originally made by a craftsman in the military, it's that kind of single-tube clairvoyance, have you seen it?"

Liu Sanwu thought for a while, and then said, "I remember that when Your Majesty went down to Yashan, there seemed to be this thing, and it was used to observe the tide and sea conditions."

After Liu Sanwu finished speaking, he couldn't help sighing, "It was just something to play with at the beginning, how could it be so big?"

Zhang Ximeng smiled and said: "It is because it is made large that it is possible to see far. To tell you the truth, if you place this thing on the top of the mountain, and encounter a clear night sky, you can observe the moon!"

"Moon?" Liu Sanwu was shocked, "Zhang Xiang, this, this is what the Qin Tianjian should use! Looking up at the sky, this is the power that His Majesty should have!"

Zhang Ximeng couldn't help laughing, "Are you worried that I will deceive you by playing around with these things?"

Liu Sanwu blushed and shook his head quickly, "Zhang Xiang does everything flawlessly and is thoughtful, how could he deceive you?"

Zhang Ximeng smiled and said, "Don't worry, His Majesty is using it on Zhongshan! He's tired of seeing it."

Zhu Ying said that Zhang Ximeng had prepared a lot of subject lecture notes, which was true, but he didn't know everything.

In fact, Zhang Ximeng still attaches great importance to the development of science and technology.

When the Zhu family entered Chuzhou, the most important thing was to protect the blacksmith's furnace and keep the workshop and handicraft industry. Afterwards, the craftsmen were the most valued in every area they conquered.

Moreover, Zhang Ximeng also entered the artisan into the military, enjoying the same treatment as the soldiers.

Subsequently, the patent law was promulgated, and heavy awards were given to inventions and creations.

These things are well documented.

It's just that in view of the gathering of warriors of the Ming army, it is extremely powerful, which makes people ignore the scientific and technological progress of the Ming army.

But these improvements are real.

For example, the armor of the army is lighter and stronger, and the weapons are extremely sharp and durable. This alone greatly reduces casualties. The casualty rate of the Ming army is very low.

Secondly, things like telescopes were made before the Ming Dynasty was founded.

Zhang Ximeng thought it would be very troublesome at first, but after dealing with several old gentlemen, such as Zhu Sheng and others, he learned that in the pre-Qin period, there was a saying that crystal stones were used to treat eye diseases.

Obviously, that crystal stone is not edible.

At the latest in the Eastern Han Dynasty, there were already craftsmen skilled in polishing crystals and making glasses.

And there are not only crafts, but also theories. Mozi records a lot of optical knowledge.

A literati like Zhu Sheng, who is old and has poor eyesight, can't see the small letters clearly, so he often wears a pair of glasses for himself to read.

After Zhang Ximeng entered Yingtian, he found a group of craftsmen who could polish crystals.

He first ordered a batch of reading glasses, carefully observed the level of craftsmanship, and then asked the craftsmen to make some concave lenses. Then, naturally, one afternoon, Zhang Xianggong, who was sitting under the grape trellis, was smashed by a grape, and suddenly had an epiphany. Then the "clairvoyant" was invented.

The appearance of clairvoyance is naturally a great help to the generals, standing tall, seeing far, and commanding is more convenient and smooth. Thousands of soldiers, such as the fingers of the arm.

But that's all.

In the end there is no subversive effect.

Zhang Ximeng pondered for a while, and understood what was going on... Crystals exist naturally, but they were polished by craftsmen and made into telescopes, which are far from being turned upside down.

What really matters is the material!

Only breakthroughs in materials can truly change the world...such as glass!

When Zhang Ximeng began to pay attention to glass, he discovered another problem. Glass is not a rare thing, it can be traced back to the pre-Qin period.

At that time, it appeared widely and was used as a substitute for jade. Inlaid decorative objects, such as jars and sword hilts, all had the habit of using glass.

When Zhang Ximeng was looking through the historical materials, there was a kind of sigh that the origin of all things is the Spring and Autumn Period.

In fact, in the land of China, there was a period of time when the importance of technological invention was attached, and there was an era when craftsmen were respected... As for why it changed later, it seems that there is no need to say more.

In addition to the very early days of glass manufacturing, Zhang Ximeng also found that there was a tradition of craftsmanship in the past dynasties. In the Yuan Dynasty, there was a special jade bureau, which, as the name suggests, was used to make glass.

It's just that from the pre-Qin period to the Yuan Dynasty, most of the fired glass was stained glass.

And the use is also different from that of later generations. Most of these glasses are used to replace jade.

This also involves a problem, that is, the glass technology developed in the past dynasties in China is different from the transparent glass that is popular in later generations, and belongs to the technology tree of lead-barium glass.

The next thing is simple, there are craftsmen, and there is no shortage of craftsmanship. Just correct the technology tree and change the route of sodlime glass to get the finished product.

But it turns out that Zhang Ximeng still thinks the problem simple.

The biggest problem with firing soda lime glass is that it requires a higher temperature, which is far less easy to fire than colored lead-barium glass.

Therefore, the furnace temperature must be raised, and then the craftsman who fired the glass came together with the craftsman who made the iron!

Ashamed to say, these two groups have never cooperated before.

Glass artisans despise blacksmiths at all... What are you playing with?

Isn't it just a worthless iron lump?

Manufacture of weapons, kitchen knives, are killing life.

Look at what we burn glass, and what we burn is called Yaoyu!

A gentleman is like jade!

We are making jade.

Only the spirit of mountains and rivers can breed jade.

What we make of glass is the creation of the heavens and the earth, and it is the means of the gods!

And our finished products are all used by dignitaries, and the queen's phoenix crown has our products.

What do you blacksmiths compare to us?

Good guy, it turns out that there is a discrimination chain in the craftsman!

Zhang Ximeng severely criticized the glass craftsman, and personally organized joint research... Not to mention, under his interference, Daming's glass-firing technology has made a leap, and finally in the eighth year of Hongwu, large-scale firing clear glass. It can also be fired before, but due to impurities, it will have a faint green color.

Until the eighth year of Hongwu, the problem was completely solved, and the yield rate reached 85%.

At the same time, the iron smelting industry in the Ming Dynasty also improved a lot.

It belongs to forging ahead and making progress with each other.

Moreover, Zhang Ximeng also found that due to the barriers of the industry, the broom is very precious, and the craftsmen are very reluctant to communicate with other people, let alone outsiders, even those in the industry are not good, guarding each other, just like guarding against thieves.

Although Zhang Ximeng severely criticized this situation, he felt that this kind of problem was difficult to solve.

Unless the basic science is spread, so that more people can understand the technology and be able to participate in the invention... The mystery of various technologies will be removed, so that craftsmen will not be able to treasure themselves. At the same time, it is necessary to improve the status of craftsmen in order to solve the problem smoothly.

So this is the reason why Zhang Ximeng decided to come to teach.

In the past few years, he has completed the rezoning of the province, reformed the official system, established the Ministry of Commerce, established compulsory education, and opened up connections with overseas.

It can be said that everything is ready. Next, we only need to promote scientific progress and explode productivity, and we can lead the Chinese people to make great progress with an unparalleled might!

But before that, Zhang Ximeng had to set off from Jiangzhou, head to Jimin Academy, and head straight for his destination.

Liu Sanwu came to greet Zhang Ximeng. Among the gentlemen who accompanied Liu Sanwu, there were Qi Tai, Lian Zining and others, all of whom were famous teachers.

Zhang Ximeng just greeted them and encouraged them.

After all, with Zhang Ximeng's self-cultivation, he can still be calm.

After all, even if it is garbage, it can generate electricity when it is sent to the power plant.

Don't discriminate against people just because they are idiots.

After all, it's not their fault that they are idiots, and the person who promoted them to that position is the fool.

Zhang Ximeng calmly went to Jimin School.

At this time, Jimin Academy was about to boil.

What?

Zhang Xiang is coming to study!

The sages of the world, the master is alive.

The right minister of King Lu, the first person to assist the emperor.

Fuguo Yuanshi!

There are too many halos on Zhang Ximeng's head, each of which can blind his eyes.

There are so many students, including teachers, who do not admire Zhang Ximeng.

Soon, the teachers and students of Jimin Academy knew good news. They needed to select a few students with excellent academic performance and go to meet Zhang Xiang.

No student is not excited, rushing to sign up!

Perhaps there is only one exception, that is Zhang Shuning!

It was the first time this kid discovered that his father was so popular?

What if I see my dad?

What if people find out that he is Zhang Xiang's son?

oh my god!

Who will tell me?

Zhang Shuning held his head and wanted to cry without tears.

But at this moment, a person came to Zhang Shuning and suddenly said, "You stand up."

Zhang Shuning stood up subconsciously. The person who came was his teacher. The teacher stared at Zhang Shuning carefully, looked at it for a while, and suddenly burst out laughing.

"What a good boy! He looks good, his grades are good, not only can he read, but he can also ride horses and shoot arrows... This is the student of Jimin Academy. He has all the six skills, it's very good, it can't be better!"

Zhang Shuning has been fooled. Why do you, a teacher, praise the students so much?

I saw the teacher smiled and said: "Shu Ning, come with me, the school has already decided, it's up to you to meet Zhang Xianggong!"

At this moment, Zhang Shuning's head was empty.

What?

Let me go meet my dad?

What do you think?

What did I tell him?

welcome, father?

Isn't this crazy?

Zhang Shuning's whole person is not well.

But how does the teacher know about this, he just thinks Zhang Shuning is happy and stupid, he can't help reaching out to hold Zhang Shuning, "Let's go, let's compare with those students! But we Shuning are good at everything, they can't do it!"

Sure enough, Zhang Shuning passed the assessment very smoothly, and the UU reading www.uukanshu.com school gave him a set of exquisite red clothes, wearing a hat with flowers on it, making him look like a groom.

"Look, this is our signboard, human appearance!"

The teachers praised him, and the classmates were very envious... As for Zhang Shuning, his blood was cold!

Just then, a horse galloped by.

"Zhang Xiang is here, there are still twenty miles left! Hurry up and welcome!"

The teachers and students shook together, and the teacher pushed Zhang Shuning, who was completely sluggish, let's go, don't delay the big event!

Just like that, Zhang Shuning, who was like a puppet, was kicked out of the school...
