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

"To put it simply, physics is the study of the internal laws or principles of things, just like the steam car you saw Your Majesty, as well as our hot air balloons in the Tang Dynasty, kamikaze crossbows and the like, which are things related to physics, even wind and rain, thunder and lightning, water and ice, that is all physical problems." Zhang Nan's explanation, Li Er didn't pay attention to it, and Li Er didn't pay attention to Zhang Nan's later questions.

Li Er only heard that the steam car, the hot air balloon, and the kamikaze crossbow were all related to physics, and that was enough.

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

"I remember that you didn't send them to the Heavenly Ministry of Works? What's wrong. Li Er still remembers these two Taoist priests who are very good at looking at them and feng shui.

"These two people are now in the chemistry research group, your Majesty, think about the power of the thunder, as long as you learn chemistry and physics well, we can even increase the power of this thunder tenfold, hundredfold, thousand. Your Majesty, think about it, what kind of concept it is. Zhang Nan said.

Chatting with people, the most important thing is to do what he likes, and Li Er will tell Li Er how important physical chemistry is to human progress It is purely to play the piano to the cow, and Li Er is also easy to get bored, but this is not the case with weapons, Li Er is an out-and-out careerist, as long as Li Er is given enough soldiers and horses, Li Er even wants to unify the earth, there is no mistake, Li Er thinks so.

So Zhang Nan talked about weapons of mass destruction, and Li Er immediately became interested.

"Yes, these two disciplines are very well opened, and I am deeply satisfied." Li Er pursed his lips, revealing a snicker, no way, Li Er loves this thing.

"That's why we have to divide the liberal arts and sciences in high school, and the science students are research-oriented talents, and they will continue to send talents to our Datang scientific research institute, that is, the Tiangong Department. As for liberal arts students. Zhang Nan smashed his mouth, he really didn't think it would be useful, after all, the liberal arts only opened two subjects, history and geography, and the Tang Dynasty was no more modern than modern, and there were very few places where the liberal arts were used, and the most important thing was that the two courses opened by Zhang Nan had nothing to do with being an official.

"Liberal arts students are also useful, although it can't be shown now, but it is definitely useful." Zhang Nan could only say an ambiguous answer.

Li Er doesn't care about these, as long as he can make weapons and send talents to Datang, then Li Er will be happy.

"Qingquan, what you said is biased, looking for you to study the law, a student must have at least more than ten years of time to study, but as soon as he left the school, he went directly to the Tiangong Department, which is probably a bit of a waste." Yu Shinan stood up and said, after all, scholars were relatively noble beings in ancient times, and aside from the social status behind scholars, being able to read and write is a respectable thing in itself.

And Zhang Nan opened his mouth to pull these students to the Tiangong Department, which made these old men a little unhappy. After working hard to study, how did you become a craftsman in a blink of an eye?

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

"That's not what the old man meant." Yu Shinan just wanted to open his mouth to defend himself, but he didn't know what to say.

"Actually, it's not to blame Lord Yu, presumably the adults present think so, craftsman is a lowly profession." Zhang Nan said with a smile.

The crowd was silent.

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

Yu Shinan shook his head cooperatively.

"I think that the teacher is the craftsman of people's souls. Think about it, if you want something to be formed, does it have to be repeatedly carved by skilled craftsmen? When the final product is present, people are always surprised by the beauty of the finished product, but don't forget, there is a craftsman behind this who has been carving it day and night, and the same is true for the teacher, if a person wants to become a talent, there must be a tireless teacher behind it, silently correcting the person's mistakes behind the back, and then continuing to impart knowledge to him, this teacher, isn't it a craftsman who repeatedly carves people? Zhang Nan's explanation was unanimously agreed by those present.

"Qingquan said this, the old man listened to it very comfortable, the old man has taught for many years, but I didn't expect the old man to know today, it turns out that the old man is also a craftsman." Kong Yingda said with a smile.

Yu Shinan also nodded noncommittally.

"Therefore, there is nothing humble about craftsmen, and those people in the Ministry of Heavenly Industry are not ordinary craftsmen, they are scientific researchers, and they are talents who have made outstanding contributions to the development of my Datang. Zhang Nan said with a smile.

"By the way, Qingquan, what you said is so hot, you can see that you are confident in this academy." Li Er suddenly thought of something and asked, since Zhang Nan said that all the disciplines were so straightforward, then the internal division of the academy must also be clear.

Zhang Nan smiled, Zhang Nan is naturally clear, after studying for so many years, how can Zhang Nan not know?

"Since the emperor has this question, the minister will simply talk about the minister's thoughts." Zhang Nan said.

Li Er nodded, and the courtiers also showed a look of deafness.

"The Tang Royal Academy is divided into three departments, the primary school, the junior high school, and the high school, and you already know these emperors. In addition to the three departments, the college has the President's Office, the Academic Affairs Office, the Student Affairs Office, the General Affairs Office, the Security Department, the Finance Office, and the Logistics Department. Zhang Nan said with a smile.

After listening to Zhang Nan's division, everyone had an expression of this kind of operation. Although Zhang Nan was sometimes very out of tune, the ministers present recognized Zhang Nan's talent in their hearts, otherwise they would not have collectively understood what Zhang Nan said.

"The principal's office is to assist the school leaders to solve the daily affairs of the school, responsible for the organization of personnel, publicity, style construction, discipline inspection and supervision, etc. Zhang Nan said with a righteous look, and Li Er couldn't stop nodding his head.

"Academic Affairs Office, management of academic affairs and teaching, teaching management, teaching supervision, teacher training, etc."

"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 capital construction, school property management, and logistics support."

"The Security Section is responsible for the day-to-day security of the campus."

"Finance Department, fund accounting, budget management, teacher salaries. To put it simply, there are just a few departments, and I will take out the more detailed rules when the academy is established. Zhang Nan said.
