"The so-called less work and more work, we scholars must endure loneliness, grasp the big and not let go of the small, pay attention to the details!

It was still quiet in front of Lizheng Academy.

For scientific exploration, research, discovery, etc., although the Qin Dynasty did not enter the scientific research community in his previous life, as a later generation, he has never eaten pork, haven't he seen a pig run?

These scientific research methods from later generations are naturally stunning in this era.

The silence lasted for dozens of breaths.

"In my previous lectures, I talked about the scientific method of experimentation. Qin Chao's voice sounded in everyone's ears again, "Then I will perform an experiment for everyone, and the name of the experiment is called the Hemispheric Experiment." ”

"Hemispheric experiments?"

I saw Qin Chao's hand move in one direction, and when everyone looked in that direction, their eyes lit up, and the delicate curtain of the carriage opened, revealing two beautiful faces, one of which was particularly beautiful as a woman.

"Please give way!"

A crisp voice sounded, and among them, the Qingli woman jumped out of the car, grabbed her hand and threw it in the car, and saw a jet-black half of the iron ball with a chain at one end flying towards Qin Xianao.

"Canopy!"

"Canopy!" The two half-sided iron balls landed on the ground in front of Qin Chao.

"Guys, these are just two ordinary hemispheres. Qin Chao picked up his foot, and a hemisphere flew into his hand, Qin Chao showed the hemisphere inside and outside to the surrounding crowd, and then looked at Yang Shi on the side, "Mr. Guishan, can you come over and check?"

"Oh?" Yang Shi raised his eyebrows, "Qin Gongzi, who can't believe it, it's okay!" He stepped forward with a puzzled look in his eyes, looked at the two hemispheres, and nodded slightly after a while, "Except for one and a half irons, there is an exit." Ordinary hemispheres indeed. ”

At this time, Mrs. Wang and Qin Wanqing had already brought other tools to the Qin Dynasty, and the Qin Dynasty picked up the pumps, washers and other tools to introduce them one by one, and then began to do experiments.

"What is this Qin Immortal going to do?"

"What does he mean by this experiment?"

I saw that the two women beside Qin Chao quickly filled the two hemispheres with water, and then put a washer in the middle and closed them together. "Next, I'm going to pump the water out of the ball. Qin Chao said. Soon Mrs. Wang connected the pump to the air outlet of the ball and began to pump water, when half a bucket of water was pumped and could no longer be pumped, Mu Wanqing tightened the faucet of the air noveil.

"Now is the time to witness the miracle. Qin Chao's voice was slightly excited, and he signaled to Mrs. Wang and Mu Wanqing again, and Mrs. Wang and Mu Wanqing walked to the horses on the side.

"Horses?"

"This horse was put here early in the morning, what is Qin Xianao doing with the horse?" Cheng Yi, Sima Guang and some others suddenly moved in their hearts, and their eyes fell on the tightly closed hemisphere.

"This ball. Didn't you part immediately after leaving the woman's hand?"

"The ball and the washer are nothing special at all, what is the force that holds them together?" I saw Mu Wanqing and Mrs. Wang each leading a horse, and then tied to both sides of the ball, causing the two horses to stand in opposite directions. "Let's go. Qin Chao's voice sounded. Mu Wanqing and Mrs. Wang waved their whips to urge the horses, only to see the two horses struggling to move forward, the chains were straightened, and then ......

"What's going on?"

"These two horses can't walk?"

"I'm still trying my best. But how can you ......?"

One by one, they looked at the neighing and wanted to move forward, but they couldn't move.

"That's right, don't doubt that you're wrong. The two horses did not pull away from both hemispheres. Qin Chao's voice sounded, "But don't worry, two horses can't be pulled, and four horses can't be pulled!"

The surroundings looked at the iron balls together in a daze.

Soon Mrs. Wang and Mu Wanqing tied a horse to the two hemispheres again, and once again raised the whip to urge the horse, but the chain was straight. The four horses panted and the iron balls were still together.

"Let's just get eight horses!"

Soon the eight horses pulled in their backs, and the iron ball still did not separate.

"Ten horses!"

"Twelve horses to try!"

"Fourteen horses!"

Fourteen horses were added, but the iron ball still could not be separated, and Mrs. Wang and Mu Wanqing urged the horses forward. I don't know who shouted 'force' all around, and then shouted the sound of cheering, but in vain, the fourteen horses pulled for a long time, and finally they all foamed at the mouth, and the iron balls still did not separate.

"Replace these fourteen horses, and then use sixteen!" Qin Chao's voice sounded, and it didn't take long for sixteen high-headed horses to be tied to both sides of the iron ball again, and the sound of neat cheering sounded again, this time the horses pulled for a while.

"Smack!"

With a loud bang, the iron ball parted!

The crowd cheered, then buzzed, and even asked loudly. "Young Master Qin, why is this?" "Young Master Qin, this iron ball really has no mechanism?" "Young Master Qin, why can't the horse open?" ......

"Everyone!"

Qin Chao's voice sounded, and the surroundings fell silent.

"These two hemispheres, everything is as you can see, there is no other mechanism, and I will leave them in Lizheng Academy, which is considered a gift to you, of course, don't let him look in the academy, you can also use it to do this experiment at any time, I will talk about it today, as for the principle of this experiment, it is exactly what we want to explore!"

"Mr. Ikawa, gentlemen. Qin Chao hugged his fists to Cheng Yi, Sima Guang and the others, "I have other things, so I won't stay long, we will have a period later!" Soon Qin Chao left.

Everyone in front of Lizheng Academy was excited.

"Why?"

"Ordinary balls will stick together if they drain the water from them, and it will take sixteen horses to pull them apart, which is ......"

"What is the bottom line of Qin Xianao's performance of this experiment, what does he have to tell us?"

Whether it was the students of Lizheng Academy, or the scholars who came from other places, or even the scholars sent by the sects, the masters of martial arts were all discussing. In front of the gate, Yang Shi walked towards Cheng Yi: "Teacher, do you want us to do this experiment again?"

"This is natural, do it a few more times!" Cheng Yi said in a deep voice.

Soon Yang Shi and others once again started a hemispheric experiment in public, and it was still sixteen horses to pull away, once, twice...... Every time it was like this, sometimes even sixteen horses could not be pulled, and it was necessary for someone to help them put it together.

Undoubtedly, everyone was a little suspicious of Qin Xianao's character, but he did it himself, inspected again and again, and experimented again and again, so it was impossible for Qin Xianao to do something.

At the end of Qin Xianao's lecture at Lizheng Academy, the martial arts people who gathered in Lizheng Academy dispersed, followed by Qin Xianao's methodological lecture on the exploration of martial arts culture in this class, as well as the 'hemispheric experiment', especially this hemispheric experiment, which caused a sensation.

Soon the new "Wulin Wind" will be on-

"It's an interesting experiment, I really wonder how Qin Xianao came up with the idea of doing such an experiment, and how he discovered such a phenomenon......

"There are several phenomena worth pondering in this iron ball experiment, when there is water in it, it is easy to separate, and pumping, the less water is extracted from the ball, the easier it is for the ball to separate, why is this ......"

"I think there must be a force that brings the two hemispheres together, and the question is whether this force comes from inside the iron ball, or from the outside of ......the iron ball?

"Where does the power to absorb the two hemispheres come from? we can see that this power is not vertical, nor horizontal, but comes from all directions, which makes me think of one thing - the earth that has recently been confirmed by Qin Xianao is spherical......"

The article on the martial arts wind discusses the internal principle of the hemisphere experiment, and people from various academies and martial arts circles will also talk about it when they meet, and many people are even more puzzled, Qin Xianao did this experiment, does he know the inner principle?

Time passed, half a month passed in a blink of an eye, and on this day, Songyang Academy was crowded.

"In addition to agreeing to Mr. Yi Chuan's invitation to give lectures, Qin Xianao also agreed to Sima Guang's invitation to give a lecture at Songyang Academy, and Qin Xianao left doubts about hemisphere experiments in the last lesson, and this time I don't know ......."

"Although Qin Xianao is sometimes very disliked, but he always surprises people, and now no one dares to ignore his affairs, the last time Lizheng Academy, but the big guys gathered, this time I don't know ......"

Songyang Academy Qin Dynasty lectures Yi, Liu Qin, Lu Gong, Zhao Tingzhi...... Scholars from one sect after another are still coming, and even more people are coming than last time.

And this time, Qin Xianao gave a speech on "The biggest difference between humans and animals is that they can make tools".

"I am a big believer in Duan Haifeng's "Origin of Species", so I believe that early human beings were not much different from the apes, orangutans, or apes and forest apes on this land......

"The development of the apes into the people we are now, I think went through the following steps. ”

"1. Walk upright!"

"2. Make and use tools!"

"3. The brain is further developed!"

"4. The production of language!"

"Walking upright is the basis of evolutionary development, in my vision, the forest apes lived an arboreal life in the forest, and then for some reason, the geology, the climate changed greatly, and the forest was greatly reduced, so that some of them had to be forced to migrate and leave the forest ......"

"Walking upright frees up the forelimbs for feeding and defending against enemies, which not only further divides the hands and feet, but also promotes the change of the body, forming a unique body structure of man......

"Making and using tools makes the brain more and more flexible, and in the process, people have to exchange information with each other to ......"

......

Shocking words echoed in everyone's minds. (To be continued.) )
