"Well, it's just that history is easy to understand. What are physics and chemistry?" Li Er asked strangely.

"Simply put, physics is about studying the internal laws or principles of things, just like the steamed car you saw, as well as the hot air balloons, god-wind crossbows of our Tang Dynasty, etc., which are things about physics. Even wind, rain, thunder, lightning, and water formed into ice, are all physical problems." Li Er did not pay attention to Zhang Nan's explanation later, and Li Er would not pay attention to Zhang Nan's subsequent problems.

Li Er only heard that steaming cars, hot air balloons, and kamikaze crossbow were all related to physics, which was enough.

"As for chemistry, it's even simpler. Chemistry is a discipline that studies the composition, structure, properties and transformation of matter. It's like our thunder, which belongs to the category of chemistry. The emperor still remembers Yuan Tiangang and Li Chunfeng, two of them." Zhang Nan said with a smile.

"I remember you took them to the Tiangong Ministry? What's wrong?" Li Er still remembered these two Taoist priests who were very good at reading photos and had good Feng Shui.

"These two people are now in the Chemistry Research Group. Master, think about the power of the Sky Thunder. As long as you learn chemistry and physics well, we can even increase the power of the Sky Thunder ten times, a hundred times, and a thousand times. Master, think about what it is just a concept." Zhang Nan said.

When chatting with people, the most important thing is to give their preferences. How important is physical and chemistry with Li Er to human progress? It is purely playing the piano for cows, and Li Er is easily bored, but it is not the case with weapons. Li Er is an ambitious man. As long as he gives Li Er enough troops and money, Li Er even wants to unify the earth. That's right, Li Er thinks.

So Zhang Nan used weapons of mass destruction to explain things, and Li Er immediately became interested.

"Yes, these two disciplines are very good, and I am very pleased with me." Li Er pursed his lips and showed a snicker. There was no way, Li Er just liked this thing.

"That's why we have to divide the liberal arts and science subjects in high school. Science students are research talents. They will continue to send talents to our Tang Dynasty scientific research institute, namely the Ministry of Tiangong. As for the liberal arts students." Zhang Nan smashed his mouth, and seemed to have never thought of any use. After all, the liberal arts only offers two subjects of history and geography. The Tang Dynasty is not as modern as it is, and there are very few places used in liberal arts. The most important thing is that the two courses offered by Zhang Nan have nothing to do with being an official.

"Liberal arts students are also very useful. Although they cannot be displayed now, they are definitely useful." Zhang Nan could only give an ambiguous answer.

Li Er didn't care about these things. As long as he could build weapons and transport talents to the Tang Dynasty, Li Er would be happy.

"Qingquan, what you said is biased. If you learn the law, it will take at least ten years for a student to study. However, as soon as he became a teacher, he went directly to the Tiangong Department. This is probably a waste." Yu Shinan stood up and said, after all, scholars were relatively expensive in ancient times. Putting aside the social status behind scholars, being able to read and read is a respectable thing in itself.

Zhang Nan was about to pull these students to the Tiangong Department when he opened his mouth, which made these old men a little unhappy. After studying hard, why did he become a craftsman in a blink of an eye?

"Hey, Lord Yu said that, he still looks down on the craftsmen." Zhang Nan looked very disappointed.

"I didn't mean that." Yu Shinan was about to defend himself, but he didn't know what to say.

"Actually, this is not the fault of Lord Yu. I believe that the adults present think so. Craftsmen are a low-key profession." Zhang Nan said with a smile.

Everyone was silent.

"Actually, craftsmen are not humble. Lord Yu, do you know how I think teaching and educating people is the profession of teachers?" Zhang Nan asked with a smile.

Yu Shinan cooperated very well and shook his head.

"I think, teacher, that is the craftsman of people's souls. Think about it, if something needs to be formed, does it take repeated carvings by skilled craftsmen? When the final product appears, people are always surprised by the beauty of the finished product, but don't forget that behind it there is a craftsman who keeps carving it day and night. Similarly, the same is true for a teacher. If a person wants to become a talent, behind this must be a hard-working teacher who silently corrects the mistakes of this person behind it and continues to impart knowledge to him. Isn't this teacher just a craftsman who repeatedly carves people?" Zhang Nan's explanation won unanimous recognition from everyone present.

"I feel very comfortable when Qingquan said this. I have been teaching books for many years, but I didn't expect that today I realized that I am also a craftsman." Kong Yingda said with a smile.

Yu Shinan nodded without comment.

"So, there are no trivial craftsmen, and the people in the Tiangong Ministry are not ordinary craftsmen, they are scientific researchers, and they are talents who have made outstanding contributions to the development of our Tang Dynasty. When steam equipment replaces most of the handicrafts, you will be able to clearly feel the power of technology." Zhang Nan said with a smile.

"By the way, Qingquan, you are so enthusiastic, you can see that you are confident in this academy." Li Er suddenly thought of something and asked. Since Zhang Nan said so well all the subjects, the internal division of the academy must be clear.

Zhang Nan smiled, Zhang Nan was naturally clear about it. After studying for so many years, how could Zhang Nan not know?

"Since the emperor has this question, I will briefly talk about my thoughts." Zhang Nan said.

Li Er nodded, and the courtiers also looked at listening with a look of scrutiny.

"The Royal Academy of the Tang Dynasty is divided into three departments, primary school department, junior high school department, and high school department. You have already known these emperors. In addition to three departments, the academy has a principal's office, academic affairs department, student office, general affairs department, security department, finance department, and logistics department." Zhang Nan said with a smile.

After hearing Zhang Nan's division, everyone looked like this. Although Zhang Nan was sometimes unrestrained, the ministers present recognized Zhang Nan's talent in their hearts, otherwise they would not have collectively misunderstood what Zhang Nan said.

"The principal's office is to assist school leaders in solving daily affairs on campus, and be responsible for organization, personnel, publicity, style construction, discipline inspection and supervision, etc. The academy is a pure land, and bad atmosphere is absolutely not allowed to run into the school." Zhang Nan said with a righteous expression, and Li Er kept nodding.

"Academic Affairs Office, manages academic affairs teaching, academic affairs management, teaching supervision, teacher training and other work."

"The Student Affairs Office is responsible for student management, student status management, and ideological and political education."

"The General Affairs Office is responsible for campus basic construction, school property management, and logistics support."

"The Security Department is responsible for daily campus safety issues."

"The Finance Department, fund accounting, budget management, and teacher salary payment. Simply put, there are just a few departments. I will take out the more detailed rules until the academy is established." Zhang Nan said.
