Xiao Xiao didn't reveal his purpose until this time. He planned to unify these different voices first like teaching mathematics before, and then let them learn on their own initiative.Some people questioned that Dr. Guozijian has no real talent and learning?I'm sorry, let's solve the quadratic equation in one variable first; someone accused Guozijian that the supervising students are ignorant?Excuse me, the perfect answer from the superintendent of mathematics is circulated; some people sneered at Xiao Xiao's lecture, thinking that he is using this incident to make a name for himself?

I'm sorry, because I'm a stranger!

Xiao Xiao's already extremely controversial lecturing behavior caused a lot of trouble in the city. Once the identity of this stranger was exposed, almost everyone lost their composure and ran to the Zuixian Tower to watch.Originally, Zuixianlou felt that there was a lot of business during this period, which was good; but when the people who crowded the whole street swarmed towards Zuixianlou, their faces turned pale with fright, and they stammered. He said that he hoped that Xiao Xiao could change places.

"Facing the twilight, the rain sprinkled the river and the sky, and it cleared up the autumn. The frost and the wind were bleak, the Guanhe was cold, and the building was left in the afterglow. It was a place where the red was fading and the green was fading, and the things were resting. Only the Yangtze River flowed eastward without words.

I can't bear to climb high and look far away, looking at my hometown for a long time, it's hard to stop thinking about it.Sighing the traces of the years, what is the pain and drowning?I want to see a beautiful woman make up the building, but I miss it a few times, and the sky will return to the boat.Fighting to know me, leaning against the railing pole, I am so worried! "

Xiao Xiao asked people to engrave the poem on the pillar at the entrance of the academy, because he felt that the poem not only contained the names of himself and Jiang Muyu, but also showed his ability to be known as the first poet of Baiyu.Although a bit shameless, Xiao Xiao thought that this was all to save Jiang Muyu, so she felt that it didn't matter if there was any retribution in the next life.Taking the first batch of students into the academy, Xiao Xiao pointed to the middle building and said to them:

"From today onwards, you are the first batch of students of Jiangtian College, and I am your teacher and the only teacher now. Jiangtian College is only full-time now, but when it develops in the future, we can also follow the class hours..."

However, the students have long been overwhelmed by this neat and majestic building complex with different styles, how could they hear what Xiao Xiao said?Although the blueprints here have their own credit, although I have been here once, but after the repairs here are complete, who would have thought that the result would be like this!

That's right, Xiao Xiao was built according to the scale of later generations of schools. Although the color of the cement is gray and the windows are not transparent enough, this is the first school in the world!

Since the day when the locusts were exterminated, Xiao Xiao had the idea to build a school, and Xiao Xiao studied this matter when she had nothing to do. Therefore, when she proposed to Liu Ziming to act as a stranger, she had a comprehensive plan in mind.Liu Ziming is also not what it used to be. The power in his hands allows Xiao Xiao to use cement and glass without any scruples, without worrying about what troubles these will cause to the royal family.So Xiao Xiao took out the dividends that Zhao Ming gave him to buy a hill outside Wangcheng and a nearby open space, and built Jiangtian Academy at the foot of the hill.During the lecture, Xiao Xiao even took the people who came to the lecture to visit here, and sent architectural drawings to tell them what the place would look like in the future.

"This is what the mathematics supervisors study every day," Xiao Xiao pointed to the deep pits that have been piled up one by one, "From small houses to large embankments, each of them is a project that requires careful calculation, and it should not be a project. I think it looks good, and I think it’s good enough to start construction. If literati write history with their pens, then architecture is the history book of stone. There is no important thought of human beings that cannot be written on stone by architectural art. Human His whole thought has its glorious page in this great book and its monument."

"That's arithmetic, and that's what I'm going to teach."

Xiao Xiao's words shocked people's hearts, and those scholars who didn't care at first but came to join in the fun suddenly felt the gap between themselves, Xiao Xiao, and those students from the Imperial College.What are those Guozijian students doing when they are boasting and looking at themselves?Finishing this country, changing this era!They despise those who come out of mathematics and are no different from those craftsmen except that they can write, but even those who have only studied with Xiao Xiao for three days can clearly realize what the role of mathematics students in a project is. The same effect-the queen can cultivate worker ants, but it is impossible for worker ants to live without a queen.

"But we won't stop here," Xiao Xiao smiled again at this moment, "Don't you want to know why the sky is blue? Don't you want to know whether there are immortals living in this sky? Have you ever thought about it? Birds can fly, why can't people?"

"Because people don't have wings." Someone replied blankly.

Xiao Xiao looked at the peasant with mud spots on his legs: "Then, have you ever thought about what kind of wings a person must have and how big they are to fly?"

"Probably as big as a heron?" replied the farmer uncertainly.

Egrets refer to the egrets outside the royal city. They are medium-sized birds, and some of them can reach three meters with their wings spread.

"Wing area should be lift divided by half speed, the product of speed, air density and lift coefficient," Xiao Xiao explained, "If human beings want to fly like a bird, regardless of the weight of the wings, it can be calculated according to this formula The result is that a 130-pound man should need wings of at least two feet two to fly."

The farmer was even more at a loss, because he didn't understand a word Xiao Xiao said.The same goes for the rest of them. Although they have learned addition, subtraction, multiplication and division these days, do they understand the speed and density?However, Xiao Xiao didn't pay attention to their puzzled eyes, but continued to say:

"But even so, it is impossible for people to fly in the sky with wings, because this is determined by our body structure. The key to flight is that the upward lift generated by flapping the wings exceeds the downward force caused by the weight, so birds can Flying in the air. A bird's bones are hollow, making it lighter; its alveoli are connected to the lungs, so it can pass air faster; and the streamlined shape of its abdomen allows these birds to fly with less effort. But we can't .”

"The growth rate of human weight is always faster than that of our own strength, so even if we have the body of a bird that can fly, we still can't swing the two-foot-two wings, so that it can produce the ability to take us to the sky."

After Xiao Xiao finished speaking, a group of people had already walked into the unrenovated building, or the teaching building.This is a three-story building, and it is also the tallest building calculated by Xiao Xiao and the craftsmen that can be completed within half a month. After all, it takes at least one month for reinforced concrete to reach the desired strength.In addition, there are two six-story teaching buildings under construction. These two buildings are made of reinforced concrete, so Xiao Xiao is looking forward to the day when they will be completed.

While showing the students a tour of the rough house, Xiao Xiao said to everyone: "The cement under our feet is the material used to pave the road; the remaining windows will be filled with glass in the future, which is also a kind of glass similar to colored glaze." But cheap and easy-to-obtain materials. These are all provided by the Ministry of Industry and researched by me."

The scholars might have guessed the relationship between the gray wall and the cement, but they still showed surprise expressions, because they didn't expect it to be cement.Hearing what Xiao Xiao said about glass and colored glaze, they all showed expectant expressions, and then planned to ask a question or two.It's a pity that Xiao Xiao didn't give them a chance, but stood in the middle of a large classroom and said to the four or fifty people: "I know you must have a lot of doubts in your mind, but don't worry, because we will help everyone one by one in the future. answer."

Later, these 45 people became the first batch of students of Jiangtian College.

When the half-month period that Xiao Xiao promised Liu Ziming arrived, he was watching these people in the classroom reading and reciting those mathematical formulas.Due to Liu Ziming's strong support for Jiangtian College, these students with excellent grades can directly enter the Ministry of Industry in the future, so the future is considered to be worry-free.Therefore, the first batch of students also settled down to study hard. In addition to working hard to make up for the gap in late study, they also took on many projects with Xiao Xiao to make money.

Glass is very popular in Wangcheng, if anyone's house does not have windows made of glass, then it is simply out of date.The Ministry of Industry sells the glass in supermarkets. A piece of glass that costs less than a penny is several hundred taels of silver, but it is sold out as soon as it is put on the shelves, and it makes a lot of money.So Xiao Xiao led the students to form a small team, and went to guide others in the installation of glass every afternoon, and made a lot of money.Real knowledge comes from practice. The students not only received money but also acquired knowledge, so they were more convinced of Xiao Xiao.

People in other places in Baiyu are also convinced of Xiao Xiao.Needless to say about Ancheng, since the outbreak of the epidemic, no one can say that Mr. Xiao is wrong; the people of Mingcheng in the midst of the war, after seeing the power of the firecracker and the continuous crossbow, are also against Mr. Xiao who invented the two weapons. I am so grateful and admired.There is also the flood in Youcheng, the locust plague in Fengcheng, which one of the disasters that endanger the survival of the people can not be resolved without the credit of Mr. Xiao?They have heard that Mr. is the legendary stranger!

Only the people in Wangcheng are still conspiring, doubting the motives of Xiao Xiao and the court.This is probably the difference between people caused by the living environment. They are not as simple as other places. They believe what the court says, but boldly doubt everything.Suspected that the imperial court deliberately shaped Xiao Xiao's image as a "foreign guest" in order to deal with Changqing; suspected that it was impossible for Xiao Xiao to have so much knowledge on his own; suspected that standing behind him was a retainer invited by the prince.So in the end, a strange situation appeared: while the people in other places were worried about the country's peril, the people in Wangcheng were arguing endlessly about the authenticity of Xiao Xiao's identity as a "foreign guest".
