The sky is clear.

In the spacious corridor of Lizheng Academy, two scholars sighed while walking.

"Songyang lectures, Qin Xian is proud of his reputation!"

"Well, I thought he would talk about the same content as in our academy, who would have thought that there would be no void under the fame, by the way, before Qin Xian Ao Songyang Academy left, it didn't mean that there was an amazing tool that could open an era, this is simply ......"

"Qin Xianao has always been so crazy when he speaks, but he is really qualified to be crazy, this is the instrument that opens an era...... Huh?" the two scholars looked at the door not far away, and a young man came out of the door with a frown.

"Brother Saxo, feed the horses again?"

"Don't feed the horses, I'm here for fun?" Qin Shengbao snorted. The two scholars didn't care, and their eyes showed excitement: "Who is it this time?" Since the Qin Dynasty left the two hemispheres in Lizheng Academy, the martial arts world has been interested in borrowing balls from time to time to do hemisphere experiments, of course, those who dare to come to Lizheng Academy are not ordinary characters, otherwise it is impossible to enter the door if they come.

Qin Shengbao glanced at the two of them coldly: "The one who wrote Da Jiangdong!"

"When was it written that Mingyue was there?"

"Dongpo monk is here?" the eyes of the two scholars shone brightly. "Master Su is here!" "Su Dongpo is here!" Soon the entire Lizheng Academy spread.

In a courtyard of Lai Ching College, iron balls, washers, water, horses and other utensils.

"Brother Su, there is no need to do this experiment, there is absolutely no mechanism in the iron ball, I can guarantee this. ”

"I naturally understand that I came this time to prove that if the iron ball is not filled with water, what will happen?"

"Not water?"

I saw Su Shi and some important figures from Lizheng Academy walking into the courtyard.

"Brother Su, you are personal. Or let's do it?"

"Naturally, it's hands-on. Su Shi laughed loudly, came to the iron ball, grabbed the half iron and watched, and soon, he injected water into the ball, and then the two hemispheres closed. The experiment began, and soon sixteen horses pulled the ball away.

"Master Su, how's it going?"

"Interesting, really interesting!" Su Shi laughed loudly, once again closed the two hemispheres together, and then directly pumped them up with a water pump, frowning one by one.

"Brother Su, you forgot to fill the iron ball with water this time. ”

"Irrigation? Su Shi smiled and used the water pump to empty it for a while. Screwed on the faucet and smiled at the person helping next to him, "Come, come and see the two Malalas." ”

"Brother Su, you are really ......" shook their heads one by one, and soon the two horses pulled the two ends of the ball, and then the others urged the horses.

"Huh?"

One by one, they stared.

"What's going on? You can't pull it away?"

"Didn't you not water this time?

They were all a little stunned, and Su Shi's eyes flashed with excitement: "Sure enough." Sure enough, it was as I thought. He glanced around with a smile and exclaimed, "Come." And two more horses!" Soon four horses pulled the ball, and then six, eight, ten, and ten horses pulled at the same time. Suddenly there was a "pop!" sound, and the ball was pulled apart.

"This ......"

One by one, I looked at the balls that were pulled apart.

"What is the reason, there is no water in it, it will be like this?"

"Haha, alright. This time, Su came, thank you for your help. Su Shi laughed, chatted with everyone in Lizheng Academy, and soon left, and on this day, an article written by Su Shi was sent to the newspaper.

There is a manor not far from the Quzi Temple in Luocheng.

"This steam engine is really good. ”

Qin Chao looked at the behemoth in front of him with a smile, and at the same time looked at the drawings in his hand, "Xiao Yu, I think you can add a throttle valve, if possible, I suggest you build a split condenser." ”

"Throttle?"

Around, Qin Yu, Qin Ze and other classmates of the Qin Dynasty when they were young pondered. Qin Yu smiled and said: "We have also thought about adding a throttle valve, but this kind of thing is not easy, so we built the current one first, as for the separated condensation, this ...... We're not thinking about it yet. ”

"Don't be in a hurry, take your time, I have an idea......" Qin Chao explained while scribbling, although the Qin Dynasty did not learn machinery, steam cars, internal combustion engines, etc., but in this life was forced to be a hard duck on the shelf, thinking too much, some of it will naturally be understood, plus the knowledge of the previous life, the thinking is relatively open.

Time passes.

"Resin, asbestos, carbon and other tests are used as insulation materials, which is worth trying. Qin Yu, Qin Ze and the others nodded. Qin Chao put down the drawings in his hand and clapped his hands: "Okay, I'll go first." Soon the Qin Dynasty left.

"That's the steam engine?"

On the mountain road, Qiu Xinmiao's white clothes fluttered, and her eyes showed a curious light.

"What you said in your lecture at Songyang Academy is that the Lingnan one that is about to be born will open a new era?" Qiu Xinmiao looked at the Qin Dynasty.

"This thing doesn't look good. Li Canghai smiled and said, "Do a little thing, the sound is louder than thunder, noisy and noisy, although you can move, but the efficiency is really not flattering, I can't figure it out, why do you attach so much importance to this thing." "After Li Canghai joined the Taiji Society, he naturally became the 'bodyguard' of the Qin Dynasty like Qiu Xinmiao.

"It's noisy and inefficient now, but in the future. "The Qin Dynasty is in a very good mood, in fact, this time the steam engine is not the first original, but the seventh, the seven steam engines are better than the other, this one is the best, but it is still very flattering.

"The invention of the steam engine did not happen overnight in history. ”

Watt's steam engine is best known, the first in real history was built by the French physicist Denis Barpen after observing steam escaping his iron pot, and it was not until nearly thirty years later that Thomas Seville built the first steam engine.

More than a decade later, Thomas Newcomen built the famous Newcomen steam engine.

Watt was an improvement on these people, and by that time it was 1769, 90 years after Dennis's first steam engine.

After one improvement after another, the Watt steam engine, the true mother of industry, was born, and then the real industrial age began.

"I can see that the steam engine is a lot of work. Qiu Xinmiao said in a deep voice, "No matter how hard they try, they will bump and bump, just like the cylinder you talked about there, according to the theory, the seal is good, the piston and the cylinder are tightly sealed, once the machine moves, the power is very strong, but in fact, it ......"

"In fact, the piston and the cylinder are extremely mismatched, and there is a serious leakage. Qin Chao smiled at the corner of his mouth, "That's right, it's not possible for people to use a hammer to make a metal cylinder and a piston completely match, no matter how clever the craftsmanship is to create the inner wall of the cylinder, the outer wall is potholed, but what about the tools?"

"Tools, machinery?" Qiu Xinmiao and Li Canghai looked at Qin Chao.

"My first, second, and even seventh steam engines, each of which is a mother engine, has only one function, and uses it to make the next one, and the specific way is to ......" The Qin Dynasty narrated the mechanical production of later generations.

Later generations of lathes are more accurate than people, and all kinds of lathes and measuring tools can easily make things that match the size exactly, which is very easy for later generations to understand, don't understand, haven't you seen it.

Qin Dynasty's explanation, Qiu Xinmiao and Li Canghai understood it, but they were still skeptical in their hearts.

In the middle of the night, Qin Chao, Qiu Xinmiao, and Li Canghai appeared in front of Qingfeng Manor.

"Childe, you're finally back. Ah Bifei also rushed out of the door, "Su Shi has come to write a manuscript, it is about hemisphere experiments. ”

"Oh!"

Qin Chaolian appeared in front of Abi in a flash, took the telegram draft in her hand, and read it.

"Childe, this manuscript, to send it or not?" Ah Bi's bright eyes looked at Qin Chao, Qin Chao glanced at it, his face was all smiles, and he stuffed the manuscript paper into Ah Bi's hand: "It's rare, it's rare! This Su Dongpo, I thought he would just write articles, but I didn't expect his vision to be so poisonous, everyone is everyone through the ages." ”

What Su Shi wrote about the hemisphere experiment was nothing to the Qin Dynasty, but in this era when everyone didn't understand the truth of the hemisphere experiment, the first thing he came up with was amazing!

"Hair, of course it must be sent!"

Soon a new issue of "New Youth" was released, and an article called "Air and Vacuum" appeared in this issue, and surprisingly the article was signed by 'Su Shi'.

"Qin Xian Ao Lizheng Academy lectures, I didn't go because I had something important to do for a while, so I didn't go, and then I heard that he did a hemispheric experiment in class......"

"I pondered for a long time, and suddenly thought of the "Physics" that Qin Xianao had written before, in the first "Sound Chapter" of "Physics", he said that sound must be transmitted by the medium, and cannot be transmitted in a vacuum. ”

"And the vacuum is nothing, Qin Xianao thinks that there seems to be nothing around us, but in essence, there is something stuffed in it, and this thing is called air. ”

Therefore, what he calls vacuum is a space where there is no air, but simply nothing. ”

"When Qin Xianao wrote about these in the sound chapter, I used to be very puzzled, because our common sense ......"

"And this time Qin Xianao demonstrated the hemispheric experiment, and the great Confucian scholars debated the principle in the newspaper, each with its own reason, but I didn't feel like it was to the point, until I thought of Qin Xianao's air and vacuum, and a thought flashed through my mind. ”

"Qin Xianao called for hands-on experiments, not completely imaginary, so I deliberately did a few experiments, and the following is the experiment I did. ”

"First, the experiment in the water hemisphere, that is, the experimental site is the ...... at the bottom of the river"

"Second, Qin Xianao's hemisphere experiment ......"

"Third, Qin Xianao's hemisphere experimental ball is not filled with water, and 'empty pumping' is carried out......"

......

As a great writer through the ages, poems, paintings, lyrics and articles, everything is unique, and even where there is well water, there are Su words, Su Shi wrote a new word, and it can be transmitted to the capital of Liao the next morning, Su Shi's fame is so big, it can be imagined, plus Su Shi is an official who is not only a Beijing official, but also often relegated to a local official, and has been a magistrate in the north and south of the river, and his reputation among the people is even better than Wang Anshi, Sima Guang and others.

As soon as Su Shi's article came out, the sales of the "New Youth" newspaper grew wildly.

Laymen look at the excitement, insiders look at the doorway, relative to the people, the martial arts world is most excited about Su Shi's article. (To be continued.) )
