Sun Yuanhua said unwillingly: "What kind of electric light and telephone, Your Majesty will give you some guidance, and the ministers can also serve." ”

Zhu Youxiao said with a smile: "The foundation of electric lights and telephones is now completely empty. I'm going to reopen a new course in graduate school, and I'm going to call it Electricity. When the time comes, I will show you the handouts, and there will be many things to discuss with you. ”

Sun Yuanhua is a little more mentally balanced. He said: "Being able to get His Majesty's guidance is what the ministers look forward to the most. Last time, the factory said that he wanted to build a cigarette machine, and the minister asked him for details, but he did not know, saying that he could only be solved by His Majesty. ”

Zhu Youxiao found a small stick and said: "It's about three inches long, so thick, with a piece of paper on the outside, and shredded tobacco shreds on the inside, tobacco doesn't know, then any silk is fine, this is what cigarettes look like." Manpower can also roll cigarettes, but I want to use a machine to be fast and the specifications to be uniform, so I want you to try to build a machine to roll cigarettes. ”

He thought for a moment and said, "A manual cigarette maker looks like this: a small wooden rack with a movable iron or wooden pole in it, and a layer of brown paper. Put the paper and tobacco together, and then push the iron rod, and the kraft paper rolls the cigarette into a small strip, and with a pair of scissors, it becomes a cigarette. ”

Mao Yuanyi said: "The minister has seen this kind of manual cigarette rolling machine, and the minister's uncle has one, and the minister can use it to study it together." ”

Sun Yuanhua said: "That's good." But is it okay to use rice paper for writing on weekdays? Do you want to make a new kind of paper specifically for cigarettes? ”

Zhu Youxiao said: "It's too extravagant to use rice paper, and I'm afraid it's not very applicable, the requirements of paper are soft and thin, so it's better to let the treasure money division make this kind of paper." ”

Wei Zhongxian said: "Shengshang, the treasure money division can only make straw paper, but I am afraid that this kind of paper cannot be made, so it is better to invite a few craftsmen from other paper mills to guide it." ”

Zhu Youxiao thought for a while and said: "No, send a few students from the research institute, and that Song Yingxing will take it with you to help the treasure banknote division improve the manufacturing process." ”

Bi Maokang, the head of the institute, said: "Your Majesty, the institute does not offer courses related to papermaking, but I am afraid that it will not help if these students go. ”

Zhu Youxiao said with a smile: "One reason, one hundred reason." Students learn not only knowledge, but also methods. This is the so-called tactile bypass. They quickly become familiar with the methods of making paper, and then they can improve the manufacturing process based on what they have learned, or design the corresponding machine, which is much better than the craftsmen who only know the fixed method. ”

Xu Guangqi exclaimed: "Your Majesty's words can be said to have exhausted the essence of learning. Only such a student can be regarded as a student who has truly learned and learned thoroughly. ”

Zhu Youxiao said: "There is too much knowledge in this world, and it is impossible for a person to learn it in his lifetime. But with the right way to learn, you can adapt quickly and make achievements in any field, and what we need now is such people. ”

Sun Yuanhua said again: "Your Majesty, the ministers have been turning coal into coke to make iron, and the effect is indeed very good. It's just that after the coal turned into coke, a large amount of black oil remained, this thing is useless, it seems to be harmful, the minister wants to ask Your Majesty to show if these things can be buried deep or burned? ”

Zhu Youxiao thought for a while and said: "I give these black things a name, it's called coal tar, and then some gas can also be used when coking, so let's call it gas." You separate them according to their properties, and you get all kinds of substances. The characteristics of these substances are up to you. In a word, nothing is useless, at most it is just misplaced, it is useless here, it may be of great use elsewhere. Let the intern graduate students do it, do whatever it looks like, figure out the role of each ingredient, and I'm sure they'll surprise us. ”

Zhu Youxiao remembered that plastic was made of the substance in coal tar, and if it could really be made into plastic, it would be fun, because the use of plastic was too wide, and if rubber and plastic could be successfully applied, Daming's scientific and technological level would be at least two hundred years ahead of the world.

Of course, Zhu Youxiao himself doesn't know how to make plastics, and he only knows a little bit about the principle, but the problem is that he can't make the substances in the principle, or he doesn't know how to separate them, and everything can only be explored by the students of the research institute themselves.

At this time, Fang Congzhe said: "Your Majesty, this pumping machine can be used to pump water from the river to irrigate the fields, but it is too expensive. ”

Zhu Youxiao nodded and said: "Yes, compared to the waterwheel, he is very inconvenient, and he also has to burn firewood, so he really can't row." But the point is here, there are some special places that may not be good for water wheels, then this thing can come into play. And the most important thing is that we can build a machine that can pump a few feet of water now, and maybe a machine that can pump hundreds of feet of water in the future, and that will be very useful. ”

He continued: "Bi Qing, if the students of the research institute create something, regardless of whether it is practical or not, they must be greatly encouraged. Like a baby, we don't know what he can do when he is a few months old, but when he grows up he may be a brave general, a great poet, a very capable official. We don't know if what looks useless now will be useful in the future, so let's build it first. Two sentences are written at the door of the research institute: make bold assumptions and verify carefully. Give students the supplies they need, and their efforts may change the world. ”

Xu Guangqi said: "Your Majesty, the Translation Bureau has translated some of the practical works of 7,000 books, and the minister thinks that this part of the books can be handed over to the students of the research institute to study first. ”

Zhu Youxiao asked, "How many books have you translated?" ”

Xu Guangqi said: "Director Yang said that he had translated a total of 75 books on machinery and weapons, and 31 books on mining and metallurgy and calendars. ”

Zhu Youxiao said: "There are only more than 100 films in more than three years, and it seems that the Translation Bureau needs to work harder." Record copies of all these books and place them in the library of the graduate school for students to study selectively on their own. In addition, we will continue to recruit talented translators who are interested in translation, increase the strength of the Translation Bureau, and translate these books as soon as possible. ”

Xu Guangqi said: "Obey, Your Majesty, there is a book "Kunyu Gezhi", which seems to be related to what Your Majesty just said about coal coking, and there are many methods of how to separate various substances, which can be studied by students involved in matchmaking, papermaking, and coking. ”
