Otaku Engineer in Great Tang Dynasty Chapter 604: The confrontation between the old and the new era (part 2)~!

"Excuse me, the giant!"

Li Zexuan couldn't help but breathe a sigh of relief when he heard Mo Huai's affirmative words, and at the same time he couldn't help being shocked. Since Mo Huai said this, doesn't it prove that this era, someone really started to realize what the universe is? , This...this makes Li Zexuan feel incredible~!

"The second question, what is strength~?"

Li Zexuan is shocked, how can Mo Huai not be shocked~? Regarding the definition of the universe, he saw from Mozi’s handwritten notes. He originally thought that this question alone would make Li Zexuan retreat. Unexpectedly, Li Zexuan, the little doll of the 14th Five-Year Plan, could actually complete the Jedi. Anti-kill, this made Mo Huai very puzzled. After thinking for a while, Mo Huai asked the second question.

"Power~? Is it the power of strength~?"

Li Zexuan suspected that he had heard it wrong, and asked uncertainly.

Mo Huai nodded and said: "Um~!"

Li Zexuan smiled, and he opened his mouth and replied: "Force is the interaction between several objects. Interaction means that the motion of an object changes due to the existence of other objects, and an object has only two attributes-mass and Speed, so force can change the state of motion of an object. If the speed of an object’s increase is defined by acceleration, the greater the force on the same object, the greater its acceleration......"

Li Zexuan unceasingly converted all the knowledge points about force in the later "Physics" book into words that the ancients could understand. Li Gang heard it in the clouds and mist, I don’t know what the ghost Li Zexuan was talking about. , But Mo Huai's pupils shrank and he stared at Li Zexuan with an extremely solemn expression. At this moment, his heart felt like experiencing a violent storm, and it was difficult to calm down for a long time.

Mozi, the ancestor of the Mohist school, once gave a detailed definition of "force" in the "Book of Mohism", saying: "The force is the reason why the punishment (form) works." In other words, force is what makes objects move. The reason, even if the effect of the motion of the object is called force. In this regard, he gave an example to illustrate, saying that it is like lifting a heavy object from the bottom to the top, which can only be done because of a powerful effect. At the same time, Mo Zi pointed out that when an object receives a force, it also produces a reaction force. For example, after two objects of equal mass collide, the two objects will move in opposite directions. If the masses of the two objects differ greatly, the object with the larger mass will not move after the collision, but the reaction force will still exist.

Next, Mozi gave the definition of "movement" and "stop". He believes that "movement" is due to force pushing, and "stop" is the end of the motion state of the object after a certain period of time. Although Mo Zi did not clearly point out that the end of the state of motion was due to resistance, he had realized that the state of motion of the object could not exist forever after the external force disappeared.

To some extent, Mozi's research in the field of physical mechanics is absolutely ahead of the entire world for more than two thousand years~! If Mohist school could replace Confucianism as orthodox, then China is likely to become the origin and prosperity of world physics~!

After talking for a quarter of an hour, Li Zexuan finally stopped. Mo Zhong and Mo Yun, the two young men, looked at Li Zexuan with no contempt. They are the core disciples of the Mohist family. Of course, there is a certain understanding of the notes and writings, but they spend most of their time learning martial arts. In contrast, their knowledge reserves in this area are far inferior to Li Zexuan~!

Unable to fight by force, and even more incomparable in terms of knowledge, this made Mo Zhong and Mo Yun, who have always claimed to be the children of hermits, very hurt~!

Mo Huai closed his eyes and digested what Li Zexuan had just said in his heart, trying to find some loopholes in it, but after a long while, he opened his eyes somewhat dejected, because he found that what Li Zexuan just said was not only It is impeccable, and it is more detailed than the Mohist classics, and even further elaborated and proved in some aspects. He has never heard of some concepts, but he has to admit that Li Zexuan speaks very well. reason.

"This question, Li County man, you got it right~!"

Mo Huai looked at Li Zexuan with a complex expression and said.

Although there are rare copies of "Mojing" that have been handed down to the world, in the context of the prevalence of Confucianism, how many people in the whole world will look through this kind of partial book~? Moreover, these theories mentioned by Li Zexuan are obviously beyond the definition of force in the "Mojing". Based on Mozi, he has expanded force into a complete and detailed knowledge~!

Where did Li Zexuan's knowledge come from~? Why does he know so many things~? There are many questions buried in Mo Huai's heart, but it is obviously not the time to ask questions, so he can only endure it.

Li Zexuan smiled slightly. Now he really "likes" the Mohist giant in front of him~IndoMTL.com~, such an advanced-thinking physics teacher, where can I find it~! Li Gang was a big help this time~!

Li Gang, the party involved, is now stunned~! He wanted to ask Mo Huai, why is this the right answer~? He just didn't understand much at all~!

Mo Huai took his hands and walked two steps in the same place. Then he suddenly flashed his inspiration, turned and asked Li Zexuan: "Question three, open flame candles, and then put a small hole, what is behind the small hole? Phenomenon~?"

After that, he fixed his gaze at Li Zexuan. Although he knew the answer from the Mohist classics, he only knew the answer to this question. He planned to embarrass Li Zexuan later.

Li Zexuan's eyes widened. He now doubts whether this Mo Huai is a traverser. He even knows the image of a small hole~? This is going to heaven~!

"Why~? Li Xian male can't answer~?"

When Mo Zhong saw this, he asked somewhat happily.

Li Zexuan was shocked and silent, but in Mo Zhong's eyes he couldn't answer.

Li Zexuan returned to his senses, suppressed the shock in his heart, and then smiled: "How difficult is this~! Behind the small hole there will be a candle flame upside-down statue, and move back and forth with the small hole in the middle, the size of the image Changes will follow. Giant, what I said is wrong~?"

As a modern engineering student, although Li Zexuan easily answered Mo Huai’s question, he also had the same doubts in his heart as Mo Huai, because small hole imaging involves the knowledge of geometric optics, Tang How could the people of North Korea know~?

He didn't know that Mo Huai only learned this knowledge from Mohist classics. The real proponent of Xiaokong Imaging was Mozi! Mozi not only studied mechanics, but also had profound knowledge in geometric optics.
