Galileo's logical chain is simple with only three links, but it is as strong as steel.

No one can raise objections, even Yang Hua, for a while, he can't organize a rebuttal sentence - if you want to mess around and confuse the water, you have to think through the front and back first.

And Zhao Ji didn't give him time, thought about it for a while, and felt that this inference really couldn't be faulted, "That's really the truth." Nodding, he smiled at Han Gang, "This theory of things is really interesting." ”

The Son of Heaven spoke, not only confirming Han Gang's victory, but also putting Gewu on the table.

Han Gang bowed his head and thanked the Son of Heaven for his approval. But although he won, he did not become triumphant. He is just standing on the shoulders of giants, and does not represent his height. For the great man who waited in the endless fog and carved out a glorious path with only his own hands, Han Gang only had the qualifications to raise his head and look up to the mountains.

And Han Gang's calmness made the Son of Heaven even more improve his evaluation of him - being pampered and not shocked has always been a rare advantage.

But then again, a win is a win. The current victory has laid a solid foundation for Han Gang's next steps, and it can be said that the first step of the dove to occupy the magpie's nest has finally come out, and the science has finally been packaged in the skin of Confucianism, and there has finally been some results.

Although Confucius would have been able to see that Gewu Zhizhi had been explained in this way, he would have shook his head and cursed. However, the science pioneered by Ercheng and the Guanxue pioneered by Zhang Zai are not the same thing as Confucius's primitive Confucianism. Anyway, it's all biased, biased to the side of science, and Han Gang feels that it is more beneficial to the future of Huaxia.

Zhao Ji patted the railing, facing the wind blowing on the Jinming Pond on the opposite side of the avenue, and slowly nodded and praised: "Zhang Zai said that the void is qi, I didn't expect him to have refined the qi and wind to such a point. Pneumatic into the wind, things fall by the wind, the most after the wind and the speed is the same, so these things, he actually came out through the grid. ”

Han Gang shook his head, although he was a little offended, he had to correct Zhao Ji's erroneous opinion: "Your Majesty, this is not the case. ”

“…… What is that? ”

"The air of the void is the qi of the beginning, the origin of all things, formless and substantial, from which all things are condensed. And the air that becomes the wind is one of all things. Although you can't see or touch it, you can easily feel it when the wind blows. ”

In fact, the biggest trouble with Qi Science is here. The void that Zhang Zai said is qi refers to the origin of all things. But this breath is repeated with the air. There are two different definitions of the same word, which is very difficult to explain.

Zhao Ji also felt troublesome when he heard it, and he didn't understand it, so he could only nod.

"The minister has a matter, I want to ask Han Gang." Yang Hui suddenly spoke at this time.

On the sidelines, Yang Hui finally came up with a flaw. Although he continued to play the chain of logic that was as solid as steel, he was able to point out what was wrong in the previous experiment. He didn't want to admit defeat, and even if he died, he would have to struggle.

Zhao Ji looked at Yang Hui, thought for a while, and nodded and motioned for Han Gang to step forward. Although Yang Hui lost his face today, and even lost his luster with the Hanlin Bachelor, the emperor would not fail to give face to his courtiers.

Han Gang said, "Please also ask the bachelor for advice." ”

Yang Hui stepped forward and stared at Han Gang: "You said earlier that the reason why the feathers fall slowly is because of the wind. I thought that the doorway was also affected by the wind when it fell, so I slowed down. And the scale has a stone in front of it to block the wind, but it will fall quickly, and it will press on the blocking stone. ”

"What do you mean by the maestro, that a doorway blocked by the wind falls more slowly than a weighed stone that is not affected by the wind?" Han Gang asked.

"Exactly!" The flaw that was finally caught, Yang Hui bit it.

"It's windy! Thirty pounds of stone can be blown away. Han Gang smiled, Yang Hui was already poor in donkey skills, and he was going to chase and fight hard, "The bachelor is thinking about it." It is important to know that the greater the windward side, the greater the force. ”

He looked away, and after facing the crowd, Yu Zhongdao, who was holding a folding fan in his hand, said, "Zhuangyuanlang, can you borrow a fan." ”

Yu Zhong was stunned for a moment, then immediately stepped forward, first saluted the Son of Heaven, and then handed the fan to Han Gang, "Of course you can." ”

Han Gang has the upper hand right now, of course, it is time to get married.

Han Gang took the fan, and his hand sank. The fan in the remainder, the fan surface is pure white heavy silk, the front is a splashed ink landscape, the landscape is beautiful and condensed between square inches, and it is made by a famous artist at a glance. There is a small poem on the back, the dragon flying and the phoenix dancing, which is also a masterpiece. The fan pendant is a knel-sized mutton fat jade, while the fan bone is ebony wood. Yu Zhong actually used such a beautiful folding fan, Han Gang needed to make sure again: "Some are too valuable." ”

Yu Zhongzhi said that Han Gang wanted to use a fan to make a verification, and said very freely: "But it doesn't hurt to use it." ”

"Thank you!"

Yu Zhong stepped back, and saw Han Gang spread the fan flat, and as soon as he let go, it fell lightly. He picked it up again and let it go vertically, and landed with a clatter. When I fell twice, the fan was unfolded, but as soon as the attitude changed, the falling speed changed.

As soon as this little experiment was done, everyone who listened to it understood what Han Gang meant. The same folding fan is open, but the windward side is different, and the speed of falling is also different.

I only heard Han Gang say: "The door blocking stone is much larger than the weighing stone, and the wind resistance is also much greater. When the two things are separated, as long as they can be put down at the same time. Dare to ask the bachelor, what will be the result? ”

Yang Hui was dumbfounded, according to Han Gang, maybe even the scales fell faster than the stones!

Zhao Ji was also surprised, originally intuitively, he felt that the heavier things would fall, the faster they fell, but later from Han Gang, he knew that the Dao should be as fast, which was barely acceptable. But now it's better, but the light one falls faster!

Han Gang is clearly bullying Yang Hui. What he said was deliberately ignoring the quality gap between the stone and the scale itself, and unconsciously shifting the problem to a simple problem of windward area and resistance.

If Yang Hui can figure out the flaws, Han Gang can take the opportunity to give a definition of the relationship between mass and force, and with the previous experiments and theories, the second law of Newtonian mechanics can be officially unveiled in public. It's a pity that Yang Hua doesn't, he is addicted to poetry and songs, and his thinking ability in science is still not enough, and he is easily confused.

Han Gang was not disappointed either. Too much indoctrination at one time will lead to problems. A simple experiment, coupled with a perfect speculative discourse, was enough to defeat Yang Hui and other opponents. The facts are all in front of him, and he can't be hard-mouthed.

As for the rest of the story, you can take your time. There are always smart people who can think through it, and then refute it, and then they can stir up the debate on the physics of the object!

This is the right way, compared to going to Hengqu Academy and simply talking about the theories that were barely blended, and being asked by Lu Dalin to the point where he was almost speechless, Han Gang, who accepted the lesson, finally found the right way.

Now Han Gang wants to strike while the iron is hot, and reconfirm the existence and impact of wind resistance with facts: "Just like a person riding a horse, the faster he rides, the stronger the oncoming wind." This means bending down and narrowing the windward side to reduce drag. ”

"Lin Guan Gou, please find two more of the same scales."

Lin Shenhe bet on the wrong treasure in front of him, how dare he disobey Han Gang now, and when he didn't move, he asked people to find two identical scales.

Han Gang didn't move, but just asked people to take out a silk scarf, tie the four corners with string to the hole in the top of one of the scales, and tie them into the shape of a parachute.

In the eyes of the Son of Heaven, Han Gang threw the two scales down at the same time. One of them fell into the water with a thud. The other is relying on a silk towel to carry the wind and fall slowly.

Waiting for the Son of Heaven's gaze to turn back from the parachute, Han Gang said: "The scale with the silk towel tied is a little heavier than the other scale, but it just falls slowly. The same experiment can be done by tens of millions of people, even by bachelors in private, and the same conclusion can be reached: the speed of falling objects has nothing to do with the weight, only with the amount of resistance. ”

He didn't forget to bring Yang Hua with him when he spoke, reminding people that the gambling account of Yang Yuanyuan, a bachelor of Hanlin, had not yet been repaid.

"I don't know what the use of this is." Yang Hui asked coldly, he had made up his mind not to speak, in case he would continue to lose face, but Han Gang provoked him. But he couldn't continue to be dumb: "Even if you know that the speed of falling objects has nothing to do with the severity, it is only related to the amount of resistance." What is the use of this one? ”

Without Aristotle's two thousand years of authority, the significance of this experiment is certainly not as deafening as Galileo's thunder splitting the fog of the Middle Ages. But as long as it arouses the interest of the Son of Heaven, it is enough. Once Zhao became interested in this, it was much easier to stuff the theory of learning from things into the new textbooks compiled by the Jingyi Bureau.

- After all, Han Gang still has a series of experiments such as the prism spectroscopy experiment, Pascal's barrel experiment, and even the siphon used to express atmospheric pressure. In junior high school physics, a seemingly simple series of experiments is the crystallization of the wisdom of many great wisdoms, if Han Gang takes it out, his mouth is as hard as Yang Hua, and he will ask what is the use, but more people will think about the principle.

But now that Yang Hui is in front of him, he still has to deal with him.

Han Gang's answer was not words, but actions. He shook his head helplessly, and looked at Yang Hui's eyes condescendingly, just like an adult looking at a child who was angry and refused to admit defeat. sighed: "Since the bachelor said so, then that's it, there should be no such bet." ”

"You!"

Yang Hui was so angry that his face turned purple and his eyes were red. If Han Gang argues with him, there will always be flaws. But Han Gang refused to debate!

Han Gang will not quarrel with Yang Hui. The higher the posture, the more embarrassed Yang Hui became. Arguments between literati, especially those of one side, are like quarrels on forums in later generations, and it is impossible to convince the other side. As long as you manage to force the other party to lose your temper, you win.

Yang Hui played Lai Pi, which is even better for Han Gang, if he really fights in front of the Son of Heaven, he will be bitten on a charge of indistinguishable respect and inferiority. And now, Yang Hua is the only one who has lost face.

Zhao Ji was also a little dissatisfied with Yang Hui's attitude, he was also a bachelor of Hanlin, how could he be such a scoundrel? But because Yang Hui is a bachelor of Hanlin, the face of the important ministers of the court should be kept for him.

"Today's matter is over, I will go back to the palace first. Don't drag on for too long this Qionglin banquet! So saying, he went down on his own.

Congratulations to the Son of Heaven Holy Drive, Han Gang looked at Yang Hui, and then looked at Zeng Bu. Since the Son of Heaven asked the Qionglin Banquet not to drag on for too long, of course he had to listen, and it should be regarded as an end. The Son of Heaven ended the Qionglin banquet ahead of schedule, which shows that he didn't want Yang Hui to continue to be angry. But he didn't pull Yang Hua when he left, and it can be seen that he didn't take too much care of Yang Hua's thoughts.

looked at the Yang element whose face turned blue for a while, and he looked like he was about to vomit blood. Han Gang said that his victory today was real. Thinking about Zhang Zai, it is not far from the Jingyi Bureau.
