Blackboards and chalk have been made by Zhu Youxiao, but they have not yet been popularized in this era when everyone is still used to brushes, but they have become commonplace in the Ordnance Department, the Royal Academy of Engineering and the Royal Academy of Sciences.

In the conference hall of the Royal Academy of Sciences, on the central wall is a blackboard painted by a mason according to Zhu Youxiao's suggestion.

At this time, Zhu Youxiao took the chalk made of calcium carbonate and burnt gypsum as the main ingredients and wrote the words "rifling" and "machine tool" on the blackboard, and explained to them in a way that these scientists could understand according to his recent self-taught understanding.

On the long table in front of him was a comparison of the real objects for him to explain, a Minérgy rifle purchased through the system and a boring machine that could be precision machined.

Zhu Youxiao didn't tell them the origin of these products that were out of the times, and the ministers, who were accustomed to His Majesty the Emperor's always coming up with some surprising things, didn't ask much, they just patiently listened to His Majesty's explanation.

From what is an arquebus to what is a flintlock pistol, and then to the rifled gun that is now named Mine by His Majesty, through Zhu Youxiao's lectures and the assistance of various materials, these scientists in the Ming Dynasty have gradually mastered new knowledge, and even Bi Maokang and others have learned to read simplified Chinese characters to learn by themselves, rather than waiting to get the information translated by His Majesty Zhu Youxiao.

Because it was explained by His Majesty himself, this has become the highest level of the Royal Academy of Sciences, and those who can sit in the lobby are almost the leaders in the field of natural sciences in the Ming Dynasty and some mature old craftsmen who already have a basic cultural knowledge base.

According to the current official statement, only academicians of the Royal Academy of Sciences or the Royal Academy of Engineering, or the technical chief of the Ordnance Department, who have obtained the official rank of the Hanlin Academy by His Majesty, can hear His Majesty's lessons and become a protégé of the Son of Heaven.

At present, the Royal Academy of Sciences, the Royal Academy of Engineering and the Ordnance Department have a complete set of technical personnel training system.

First of all, the Ministry of Industry and the Inner Palace Supervisor will go to various places to recruit craftsmen to Beijing, or directly recruit apprentices from the people, and after recruiting, they will carry out literacy eradication.

Literacy teachers are naturally children or alumni recruited from all over the country.

Although these people may not be very knowledgeable, it is naturally impossible to teach these people to read a few words, and in order to speed up the literacy process of these technical reserve talents, Zhu Youxiao ordered the officials in charge of this matter to determine the salary of these old children or old students based on the number of people they can teach to read within a month.

In addition, Zhu Youxiao also asked the officials of the Hanlin Academy to compile a dictionary of commonly used words, the "Tianqi Dictionary".

There are about 1,000 words in this dictionary, and the criterion for success in literacy is the ability to recognize all the words in the Apocalypse Dictionary.

The craftsmen who have learned the characters are assigned to work as assistants in the bureaus of the Military Armament or the laboratories of the Royal Academy of Engineering according to their respective skills, with the veteran craftsmen taking the lead.

Apprentices, on the other hand, sometimes need to send a special veteran craftsman to teach their skills.

Since His Majesty has abolished the craftsman registration system and clearly stipulated that he must obey the regulations of the imperial court and teach the family skills to the apprentices designated by the imperial court, and he is not allowed to hide his private skills, some old craftsmen have to teach each other, and of course the imperial court will also give subsidies.

Once an apprentice or craftsman can independently complete a certain skill, he can enter the Royal Academy of Sciences for further study, and choose to listen to the lectures of Xu Guangqi, Song Yingxing and other bigwigs, or His Majesty the Emperor Zhu Youxiao.

Those who have completed the course and have mastered the core skills will become academicians.

After becoming an academician, you can directly apply for funding for the research and development of certain new things to His Majesty the Emperor Zhu Youxiao.

Of course, when the excerpt is played, it has to be copied to Xu Guangqi.

Once His Majesty Zhu approved and Xu Guangqi signed, any academician could get a project payment ranging from 1,000 to 10,000 taels or even as high as 100,000 taels from the Ministry of Industry.

Once an academician of the Royal Academy of Sciences or the Royal Academy of Engineering has applied for a generous project funding, he will take the lead in organizing various craftsmen to complete the research and development of the project.

And generally speaking, the money is much more than the actual research and development money, and therefore, many academicians want to apply for project funds, after all, they can not only get rich rewards or even increase their official ranks, but also make a fortune.

But not everyone can come up with a good idea casually.

What's more, there are still some ancients who didn't take these so-called technological innovations seriously before, and completely engaged in the accumulated experience to improve the process.

Therefore, Zhu Youxiao's classroom content has become the greatest source of inspiration for technological innovation.

This is also the reason why many people want to come to His Majesty's lectures, because every time His Majesty throws out a new thing, it means a new opportunity to make a fortune.

If you understand or memorize it, and if you go back and do the experiments, or feel that you can realize what Your Majesty said, you can write an excerpt application.

Once the Ministry of Works and officials from the Royal Academy of Sciences or the Royal Academy of Engineering have calculated how much money you need for the project, they will send you a notice and release half of your funds in advance.

Chen Litou, an old craftsman who used to be a glass craftsman, has now undertaken such a task, that is, to make the kind of large mirror that His Majesty placed in the Royal Academy of Engineering.

Because it was a subject that His Majesty the Emperor and Master Song of the Royal Academy of Engineering attached great importance to, the process of the old craftsman's application was also very easy, and it was approved in less than four or five days, and a lot of silver taels were allocated to him.

Of course, Chen Letou also made a lot of preparations before applying, as an old glazer who has been in the court for decades, he now knows that the glass and the glass displayed by His Majesty are composed of silica as the main component, but the glass is mixed with iron and other impurities, which makes it not as transparent as glass.

And the film plated on the back of the mirror is also silver, but the silver on the back of the mirror can't be buckled, and the color is different.

Chen Letou once thought about beating the silver foil very thin and sticking it behind the glass, so he also bought a piece of glass from a Westerner at a high price, but he was disappointed.

Chen was not discouraged, he first went to find what His Majesty called quartz sand and pure caustic soda according to the information given by His Majesty to make green glass.

Then, he and several craftsmen from his research group went to the manganese mines near Gyeonggi to find manganese dioxide, and then conducted a month-long experiment to finally get the transparent glass out.

But this is only half done, Chen Letou forced himself into the library of the Royal Academy of Engineering to live for nearly half a month in order to coat the silver film behind the glass.

He used to respect words and stay away, but now he has become an old pedant, and what he mutters in his mouth is either silver or iron, and those who don't know think he has crossed over.

After Zhu Youxiao found out, he even personally summoned Chen Letou and his team, and Zhu Youxiao also personally instructed them how to use silver nitrate and ammonia water to make silver ammonia solution, and use glucose water to reduce ammonia water to make a silver mirror.

In the end, it didn't take long for Chen Letou to present a silver mirror with independent intellectual property rights to Zhu Youxiao, and this silver mirror was three feet long and one foot wide.
