Li Mengxi calculated that for this first academic gathering, 80,000 yuan was distributed at one time.

The result is that of the dozen or so problems in the small ball experiment, not a single one has been solved, at most half of them have been solved.

For the purpose of solving the problem itself, this has somewhat failed. Apart from solving the problem itself, the harvest is too much and rich.

The gains from this gathering include, but are not limited to, the beginning of the research and development of perpetual motion machines, the beginning of material research to find the smoothest materials, the beginning of the technical ascent of making the smoothest planes, and the craftsmen made a lot of various inclined wood and wood.

track, and thus, the experimental equipment project began.

Branches arising from these accidents, such as perpetual motion machines, are impossible to successfully develop. However, in the process of exploring perpetual motion machines, there will inevitably be a bunch of wind, gravity, magnetic, hydraulic, mechanical, and air compression forces.

, and other power machines driven by various forces.

When it comes to finding the smoothest materials, this is materials science. What materials science can bring is what will be brought to the craftsmen when they look for various smooth materials.

As for testing equipment, experimental equipment is not an ordinary tool. The precision requirements of testing equipment are among the most sophisticated. This may directly give birth to an industry with extremely high technical capabilities.

When it comes to making a smooth plane, smoothness involves the regularity of the plane, the reduction of friction, and the technology of regularizing the plane. It can make complex instruments, and the technology of reducing friction is a subtle and micro-technique that can be used to process precision machine tools.

This is just an additional gain brought by the small ball experiment.

In addition, a lot of questions were raised.

In the City Lord's Mansion, Li Mengxi was flipping through the recorded questions with great interest.

He looked at them one after another.

“Why are there male and female chicks?”

This is knowledge like biology and genetics.

"Ask why autumn is cold and summer is hot?"

This belongs to geography, climate, environment, astronomy and so on.

"Ask, why is iron hard and wood soft?"

This involves biology, materials, mechanics, structure, and other fields.

"Ask, why are the trees tall and the grass short?"

This is a living thing.

"Why does water flow eastward instead of westward?"

Geography, landforms, earth, mechanics.

“Why can grain make wine?”

Microbiology, chemistry, food field, industrial field.

"The sun is warm and the moon is cold, why is it so?"

Celestial bodies.

"Why is it like this when there are many stars and moons?"

Astronomical universe.

…

Judging from Li Mengxi's forward-looking perspective from two thousand years in the future, he can almost see how much trouble will arise if every issue is explored further.

Such trivial details hide infinitely vast problems. When I first collected them, there were hundreds of them.

If you ask a question, it is a starting point for thinking and the first step of discovery.

Well, from that day on, hundreds of discoveries began.

Li Mengxi decided to post all the questions, just like posting a list of talents, and put all the questions in the public. But if there is anyone who can answer the questions, no matter the traffickers, the Julu people, or the passing merchants, beggars, refugees and scholars, as long as they meet

As long as you want to answer the question, no matter how high or low you are, you can answer it directly.

Julu City does not have enough places to post questions. Even if you can find a place to post them, if you post the questions in front of the house and behind the house, they will be too scattered.

The only place that has enough space, is neat enough, and is conspicuous enough is the city wall of Julu City.

Li Mengxi issued a task to the craftsman camp, asking the craftsmen to hang all the problems on the city wall for people to view. His requirements were: first, it must be strong, and second, it must be durable, and the writing cannot be wiped out when it rains.

Already.

After receiving the order, the craftsmen inadvertently gave birth to a new technology.

At first, the craftsmen thought of writing on wooden boards and then adding a rainproof roof, but it was too complicated.

And because the art of carving wood was already available in the army, the craftsmen thought of carving calligraphy directly on the wooden boards. But the problem was that there were not many literate people in the craft camp, and there were even fewer people who had the skills to carve calligraphy. In addition,

In the book, when Li Mengxi heard that the craftsmen wanted to engrave text on woodblock scripts, he immediately stopped this practice. Woodblock technology is an important technology, and it is still waiting to be printed and sold for money, so it must not be exposed.

The task was huge, the production was difficult, and the time was tight, so the craftsmen had to think of other clever ways.

The final method that the craftsmen came up with was to use a red-hot iron rod to use as a pen to write directly on the wooden board, which was fast and strong.

——

Three days later, on the outer wall of Julu City, from both sides of the east city gate to the outside, at a height of one and a half people from the ground, wooden signs were hung neatly every other step.

After the wooden sign was hung up, without any special reminder, the people in Julu City went out to watch. They circled the city wall and went under the wooden sign to look at every question hanging on the wall, that is, those who were illiterate.

, they also looked up with their eyes wide open. When listening to other literate people reading the questions, they would think about it in their minds, with a vague urge to answer the questions.

The hundreds of questions hung on the city walls were originally collected from ordinary people. Most of the questions were commonplace questions, such as flowers, grass, fish, insects, etc. There was nothing profound about these questions.

This enables even an illiterate person to have confidence.

Lu Zhi was also mixed in with the crowd milling around under the city wall. After Lu Zhi finished reading most of the questions, he looked at the bustling crowd lingering under the wall. Among the crowds, there were many small peasants, old and weak, and even blind people.

Woman, Lu Zhi sighed.

Lu Zhi did not understand the meaning of these questions by Li Mengxi, but Lu Zhi saw in the common people an extremely ardent desire to learn.

Even if Lu Zhi thinks that why chickens lay eggs is not knowledge at all, the farmer's wife and others can think over and over about why chickens lay eggs, which is the ultimate knowledge in itself.

Lu Zhi was deeply moved by this. He found Li Mengxi and wrote a preface to Li Mengxi. The preface quoted an article from the Pre-Qin Dynasty's "Tianwen",

Wen Wei, [At the beginning of ancient times, who preached it?

The upper and lower parts of the occupancy are not visible, so why test it?

Occupying the position of darkness and darkness, who can be the best?

Position occupier Feng Yiweixiang, how to recognize it?

Occupying the position is light and dark, but what is the time?

…

What is the origin and transformation of the three combinations of yin and yang in position occupancy?

If you occupy the position, it will be nine levels. Which camp will save it?

What is the merit of occupying the position, and who did it first?

How can the position of intercession be connected, and how can the heavenly pole be added?

…

What's the point of occupying eight pillars, and why should the southeast suffer?

On the occasion of occupying the position for nine days, how should I place my belongings?

…

】

A heavenly question that is in line with the main purpose.

Among the 14 departments of Julu Military and Government, the Science Department is personally led by Li Mengxi. The former Science Department gathered all the top craftsmen, collected all the top technologies, and climbed to the peak of technology.

Now, there is half more content.

Now the Science Department needs to be responsible for collecting all questions and receiving answers at any time.

The Science Department needed someone to be in charge all the time and someone to have time to take care of collecting issues. Li Mengxi felt that Lu Zhi was free, so he invited Lu Zhi to be in charge of collecting people's questions, and Lu Zhi happily accepted.

From then on, all questions about heaven and earth, and all things in the universe, were included in "Heavenly Questions".

The subordinate structure of the Ministry of Science has added the "Tianwen" Department. The dossier that records questions is also called "Tianwen". All answers and answers will also be recorded in "Tianwen".
