Luo Guangde's size is a little taller and bigger than Zheng Sen, but he really didn't see Zheng Sen in his eyes these two times, not to mention anything else, just the scattered footwork when he rushed over, Zheng Sen was sure to put down this guy within two moves, not to mention that Hai Dafu was still next to him, Hai Dafu's legs were wrong, and his skills were not as good as before, but it was not a problem to deal with Luo Guangde.

Zheng Sen took a slight step back by half a step, ready to prepare, as long as Luo Guangde really pounced, he would first turn sideways and give way to the front, and then stretch out his foot to trip him, with Luo Guangde's footwork, Zheng Sen felt that it was no problem to trip him and chew mud. However, Zheng Sen's blow didn't come out, and even this was not because Hai Dafu stopped Luo Guangde, but because Luo Guangde had just rushed out, he was grabbed by the back collar with one hand, pulled a backward back, and then sat on the ground with his buttocks, probably because he fell and his butt couldn't get up.

The person who grabbed Luo Guangde was Ma Shiying, Ma Shiying pointed to Luo Guangde who was sitting on the ground and scolded: "You are also worthy of being called a scholar?" Talking to a child, I can't make sense, and I want to bully other people's children by relying on my age? Do you want to be ashamed? Moreover, bullying a child, you actually have to call everyone to go together, you think that the other gentlemen of the Restoration Society are just as shameless as you! ”

Luo Guangde was dizzy, and in the face of Ma Shiying's scolding, he couldn't speak, and in the eyes of others, he became more and more unreasonable. I watched Ma Shiying flick her sleeves for the last time, and put on a look like I didn't bother to talk to you. Suddenly ashamed, he glared at Zheng Sen and Ma Shiying fiercely, and then reluctantly got up, and left without saying a word with the support of the scholar.

Zheng Sen hurriedly bowed his hand to Ma Shiying and said, "Thank you seniors for your help." ”

Ma Shiying shook his head and said, "The old man just can't get used to people bullying children, but the old man doesn't fully agree with your statement." But the old man hasn't figured out how to refute you for the time being. ”

Zheng Sen listened, but saluted Ma Shiying again: "It is common to have arguments in learning, and the Book of Songs says: 'There are bandit gentlemen, such as cutting and learning, such as pondering and grinding. Most of the world's knowledge is pondered in the process of asking difficult questions. The seniors are willing to think about how to refute Zheng Sen, which is to help Zheng Sen improve his knowledge. For this, the kid naturally has to thank his predecessors even more."

After this incident, Zheng Sen originally thought that the atmosphere behind him would be greatly affected. Who knows that those gentlemen of the Restoration Society didn't take this matter to heart at all, how to play, how to have fun. It doesn't seem to be affected at all. Some people also came up to talk to Zheng Sen, such as Yang Wencong.

"Zheng Xiaoyou, I've heard Chen Hongshou talk about you more than once, and when I saw it today, it really deserved its reputation. I heard Chen Hongshou say that you talked to him about some of the particularities of Westerners' painting, and I listened to some of them, and I felt that what they said also made a little sense, as the so-called stones of other mountains can attack jade. So I want to know a little more about Xiaoyou here. ”

……

After the meeting ended, Fang Yizhi and Gu Jiang came over and said to Zheng Sen, "Is there anything wrong with Da Mu?" If nothing else, we have a few more things to discuss with Oki. ”

Seeing that these two people were caught, Zheng Sen naturally had no reason to disagree, so he said, "I don't have anything to do today." I have a small courtyard near Jiming Temple, the environment is not bad, if the two of you are free, you can go to the humble house, let the boy also be the host. ”

Fang Yizhi listened and said with a smile: "I heard that Chen Zhanghou recently drew a picture of Qu Zixing for you. I'm going to see it! ”

So Zheng Sen successfully abducted the two back.

……

Entering Zheng Sen's small courtyard, Zheng Sen first took the two of them to the lobby to see Chen Hongshou's "Qu Zixing Yintu". However, the two of them were actually not thinking about this, but after a few words, Fang Yizhi asked, "What has Da Mu been studying recently?" ”

Zheng Sen replied with a smile: "I sometimes have the problem of being greedy and chewing, some time ago I was studying the characteristics of the movement of objects in the flow of water, as for now, one is to learn in the Guozi Prison, and the other is to solve the problem of the limit without self-determination. ”

"What is the question of limits." Gu Jiang asked.

"Do you two brothers know why I said that even if the results are deduced from the most reliable natural knowledge, even if the process of derivation seems to be without problems, it must be tested by practice?" Zheng Sen looked at Fang Yizhi and Gu Jiang, "Because, based on the most reliable and intuitive knowledge and deduction that seems to have no problem, it is also possible to deduce absurd results." Well, there is a famous paradox on the side of the Tessians, called 'Achilles can't catch up with the turtle', I don't know if the two brothers have heard of it. ”

"I've never heard of that. I don't know what kind of paradox this is. Fang Yizhi said.

"Achilles was a legendary warrior of Tessie, and he was said to be good at running. It may be similar to our Chinese Qingji Gongzi. Let's use Qingji Gongzi to talk about things, this sounds more convenient. Well, let's say the turtle is in the armor position, and Keiji Gongzi is somewhere behind the turtle. Before Qingji Gongzi catches up with the turtle again, he must first pass through the first position, right? ”

"Of course? Could there be anything wrong with that? Fang Yizhi asked.

Zheng Sen smiled and said, "No matter how fast Qingji Gongzi runs, it will still take a certain amount of time to reach the first position, right?" ”

"Not bad." Fang Yizhi replied. However, Gu Jiang's face seemed to change slightly.

"When Qingji Gongzi arrives at position A, even if the turtle climbs slowly, it should have climbed forward for a while and reached position B, and when Qingji Gongzi reaches position B, the turtle must have reached position C, and so on, and finally ......"

"In the end, Qingji Gongzi won't be able to catch up with the turtle!" Gu Jiang's face turned a little pale.

"Yes, and we all know that not to mention Qingji Gongzi, even any of us, it is an easy thing to catch up with a turtle. But the basis of this derivation is also based on what we think is a very intuitive phenomenon, and the process of derivation seems to be very intuitive and there is nothing wrong with it. Therefore, even a very reliable derivation that seems to be based on intuitive phenomena can lead to a wrong conclusion, so even if it is so reached, it needs to be proved by reality. ”

"I still think the derivation process may be wrong." Gu Jiang said.

"What Brother Gu said is similar to what I think. Although A is preceded by B and B is preceded by C, the distance between A and B is certainly longer than that between B and C, and the distance between B and C is certainly longer than that between C and D. Naturally, the time consumed in this way is getting shorter and shorter. Isn't the sum of an infinite number of extremely small not necessarily equal to the greatest? Fang Yizhi also said.

"Brother Fang really knows everything!" Fang Yizhi's sensitivity surprised Zheng Sen as well, "The question of the research limit I am talking about is the question about this. ”

"How's it going?" Fang Yizhi hurriedly asked.

"There's not much progress yet." Zheng Sen spread out his hands, calculus or something, now is not the time to throw it out.

……

It was also at this time that Gu Hengbo was also talking to Li Xiangjun.

"Xiangjun, in fact, you don't have to be frustrated, in fact, if you want me to say that you have performed well today, and in a sense, you have also made Zheng Damu famous. Zheng Damu should not be a cautious person, and he will not deliberately trouble you again. Moreover, you can be regarded as leaving an impression on him, and you will have an excuse to contact him more in the future. Gu Hengbo said to Li Xiangjun while holding a paintbrush to paint.

"Zheng Sen? That's still a kid. Li Xiangjun pursed his lips.

"People and you have been for a year." Gu Hengbo smiled, "If you want me to say, this is also fate." And Zheng Damu is such a smart person, do you really think that people are children who don't understand anything? Well, Xiangjun, how about I add a butterfly here? ”

Li Xiangjun looked at it very seriously and said, "Of course, it's good for my sister to say this, but I think it's too noisy to have butterflies." ”

Gu Hengbo straightened up, looked at the picture seriously, and then sighed: "It's really a bit of a trouble." But how lonely would this flower be without butterflies? So he put down his pen and added another butterfly to the painting.

"So be it." Gu Hengbo put down the pen, sighed again and said, "Xiangjun, for us, in fact, reputation or anything is fake. Don't fool yourself too. Women, no matter what the scenery was in those years, there is always a home in the end. In fact, compared with those generations of scholars, the Zheng family is even better. What do you think, those people, there are always a lot of rules, people like us, into such a family, I am afraid that I have to pay attention to it step by step, and I easily say the wrong word, even if the man spoils you again, the above is still with the father-in-law and mother-in-law, and the original wife, but the result is ...... afraid, the story of Du Shi Niang's angry sinking treasure chest is actually reasonable. However, the Zheng family was originally a family of military generals, and most of the father-in-laws and mothers-in-law above would not care too much about the origin of one of their son's concubines, and Zheng Damu was a talented man, not the kind of coarse person who didn't know how to pity the fragrance and cherish the jade at all, and he wouldn't appreciate the benefits of us at all. Don't look at Zheng Damu now, he doesn't seem to be very good at writing poems and lyrics, but in fact, his literary talent is not bad. Have you heard of the inscription he gave to Mr. Yu Shan's cane? Is that something that a person without literary talent can come up with? As long as you get his favor and know a little bit of proportion, you don't have to worry about the days to come. You say, isn't this Zheng Damu a good person? ”

Li Xiangjun blushed, took a sip lightly, and then said, "Since this Zheng Damu is so good, why don't you catch him quickly, sister?" You knew him first. ”

"Me?" Gu Hengbo smiled self-deprecatingly, "Sister, I'm not young, I can't wait for him to grow up." ”
