Half a month.

The entire city well of Beiping is full of topics about the big iron ball experiment.

"The big iron ball experiment illustrates the existence of a vacuum."

I went to the scene to see the people who had seen the experiment, and I told the people who didn't go with relish.

"What is a vacuum?"

Someone asked rhetorically.

"A vacuum is a vacuum, and you don't understand it."

"Hush."

The topic ends unpleasantly.

Life goes on, without the slightest change, people still live their old lives, the topic is quickly forgotten and new topics are started.

King Yan went out on the expedition and won?

Why hasn't there been any news at all?

That's what matters to the people.

Only the iron smelting plant is in full swing.

Daming government-run iron-smelting institutions, a total of 13 in the country.

There is no in Peking.

The iron smelting institute in Beiping was managed by King Yan.

Wansan is a well-known craftsman in Beiping, and his disciples and grandchildren are all over the place.

Because of Wansan's name, Zhu Gaochi took the initiative to find him.

Just have a name, no real craftsmanship, you can't get mixed up in Daming.

Therefore, Zhu Gaochi is not worried that the other party is indiscriminate, and those oral experts in later generations.

Since returning from the experiment, Wansan has begun to stay at home and work behind closed doors.

Soon a long pipe was made and placed in a well, and according to the vacuum principle, the vacuum device was successfully manufactured.

But there is a problem that cannot be solved.

"When the water is pumped to a height of three feet, it can no longer be raised, and all the methods that can be thought of are exhausted, but to no avail."

Dealing with Zhu Gaochi for a long time eliminated the sense of awe, and Wan Sancai deeply felt that the eldest prince of Yanwang was approachable.

In terms of his own craftsmanship, Wansan has returned to what he should be.

Zhu Gaochi is a strong mouth, and if he does it, his true form will be revealed.

But in the end, we have experienced the era of the information explosion.

Although many things are not precise, they can be said one or two.

In the Ming Dynasty, anyone could bluff.

At least in the eyes of the old craftsman Hu Wansan in front of him, Zhu Gaochi belongs to Lu Ban in the world, and he is extremely talented, and God appreciates food.

Pity.

It's a nobleman.

A waste of good talent.

Otherwise, wouldn't it be beautiful to accept yourself as a closed disciple.

"It's not water pumped out of a vacuum." Zhu Gaochi looked at it carefully and said affirmatively: "This water is not sucked up in a vacuum, but at the bottom of the well, it is pressed by the weight of the atmosphere and enters the pipeline. ”

Zhu Gaochi proved his talent.

For example, if he discovers the existence of a vacuum, then when he mentions something new, the old craftsman Manzo can accept it, and he will only think that he doesn't understand.

"A vacuum cannot exist in the atmosphere."

Wan San endured the old face and asked embarrassedly: "What is the atmosphere?" ”

"The atmosphere is the air that surrounds the land."

There are many craftsmen in the iron-smelting plant in Beiping, but only a few are called the head craftsmen.

The ancients had a high thirst for knowledge.

In order to seek knowledge, the ancients were willing to give their lives.

As the sage said: "Before I was born, he heard the Tao before me, and I learned from him; After being born to me, he heard the Tao before me, and I learned from him. My teacher is also the way, and the husband knows that he was born in my year? ”

It shows that there is no order to learn, and the one who achieves is the first.

There is also shameless questioning and so on.

Vacuum is new knowledge, and the rest of the craftsmen are unwilling to be surpassed by Wansan, so they take the initiative to surround them.

Wan San pursed his lips, and he had no choice but to let them listen.

"Atmosphere is air."

Everyone knows the air.

Taoists call it "empty qi".

Su Shi's "Treatise on Lead and Mercury of the Dragon and Tiger" recorded: "When the party is pranayama, it is rinsed and cooked, and it must be full of mouth and then swallowed." If it is not full, and it is left in the mouth, waiting for the next time, it is still sent to the dantian with air, and it is often raised with intention. ”

However, at this time, people's concept of air is still retained in the impression of breath, vitality, and clear air.

Don't laugh at them, though.

The views of the ancients were not far behind.

The experiment of the horse-drawn iron ball is still 300 years later.

Zhu Gaochi briefly introduced the lower atmospheric pressure, and then told Wan San why his invention failed.

"Until the weight of the water entering the vacuum part of the pump is equal to the weight of the water in the atmosphere, the water does not rise."

"The vacuum is not destroyed, but balances between the weight of the water and the weight of the air that cancels it out."

The craftsmen pondered.

After all, the head craftsman is the head craftsman, Wan San quickly thought of it, and proposed a method: "As the eldest prince said, if you use a juice heavier than water, the height raised will be lower than the height of water." ”

"Try it with mercury."

As soon as Wan San's words fell, the craftsman next to him immediately proposed.

"The atmospheric pressure in the mountains is smaller than that on the seaside, and you can compare it with mercury and you can easily draw conclusions."

Zhu Gaochi's words made the craftsmen happy, and they couldn't wait to try it now.

It's different from everyone else.

Wan San knew what Zhu Gaochi wanted, held back the curiosity in his heart, and raised the question that Zhu Gaochi cared about.

"Our iron tools are made according to the theory of the eldest prince, why did they fail?"

"Because there's air in there, it's not all vacuum."

"Isn't it enough to get to this point?"

Manzo felt discouraged.

In his cognition, he couldn't think of any other way.

How to solve the vacuum problem completely?

Looking at the frustrated craftsmen, Zhu Gaochi was not discouraged.

The discovery of the vacuum, how to completely solve the vacuum problem, has plagued Western countries for hundreds of years, how many people brainstormed, where is Wansan can easily figure out.

However, Zhu Gaochi did not lose confidence.

Steam engine.

He must make it.

Because he was confident in the abilities of ancient Chinese craftsmen.

Most of the inventors in the West, like Mansan, were craftsmen.

Countless inventors, who also started as apprentices in factories or were craftsmen themselves, did not have a better literacy rate than Chinese craftsmen.

The inventions of Chinese craftsmen in ancient times, and the goods they manufactured, have always been the core monopoly in world commerce.

The huge trade deficit has allowed countless silver to enter China, turning a poor country into a country that uses silver as currency.

By what?

The ancestors were handsome, so they could be eaten?

Western civilization surpassed Eastern civilization, in addition to the later castration culture of the Qing Dynasty, which regressed Eastern civilization, the most important thing is the industrial revolution in the West.

Everything else is.

Many self-media attract traffic with various self-deprecations, and ordinary people lose self-confidence and do not believe in domestic books, but only believe in foreign books.

But they haven't read it, and they don't know that other foreigners' books don't say so.

Western scholars have clearly pointed out that it was only the British Industrial Revolution.

The General History of World Science and Technology written by the Americans, which clearly states that before the fifteenth and sixteenth centuries, China's technology on the whole surpassed that of the West.

Therefore, Zhu Gaochi wanted to make a steam engine in the early Ming Dynasty, not wishful thinking.

With the technical ability of the Ming craftsmen, they only need to provide directions, and they can't make them to be called Arabian Nights.

Just like two hundred years later, the Dutch sea coachman, their most powerful Galen warship, was not easily imitated by the Ming craftsmen.

The more people who read and know more about history, the more convinced they are of the wisdom of the ancients.

They didn't lose.

Always running in the world's first column.

During the Qing Dynasty, the steam engine, the mother of industry, was invented in the West and was a sign of the new era.
