It seems that I am still too full [travel]

Fu Yu ate the raw porridge and the barbecue on the table happily, and finally got to eat Mr. Xie's craftsmanship again. Fu Xiaopang couldn't stop there, he ran directly to the chef who was making barbecue on the corridor, imitating himself Baked and eaten, according to his words, don't have a self-sufficient fun!

When the other students saw it, they also imitated him, and started to do it themselves in a decent manner.The grilled food has already been marinated, you only need to brush a thin layer of oil, and pay attention to turning it over so as not to burn it. Generally speaking, it will not be unpalatable, after all, the seasoning is made by Xie Shi himself.So a good meal, led by Fu Yu, turned into a barbecue buffet party in the end, and the joyful laughter of the students filled the quiet fishing village.Xie Shi took a look and assigned them a task. Since you guys like to do it, then bake more and bring them back to the villagers who are staying overnight.

The bright moon gradually climbed up the treetops, and after a meal of delicious food, coupled with the joyful mood as if stepping into the spring, even if the conditions of the fishermen’s houses where they lived after nightfall were not satisfactory, the students of the academy did not complain too much .

On the second day, this group of energetic students got up early again, and under the leadership of Xie Shi, they went to watch the spectacular sunrise on the sea.After admiring the sunrise, Xie Shi took out the binoculars again, and made the same request as yesterday, asking them to observe how the fishing boats going out to sea disappeared from people's sight.

Although Xie Shi's request was strange, the students who had been "bought" by Xie Shi's delicious food last night obediently complied, and the students' curiosity about the telescope hadn't passed yet!After making sure that every student had seen it clearly, Xie Shi directly ordered a student, "Mr. Liang, tell me, what did you see first when the fishing boat returned?"

The student who was named was the one who spoke yesterday and said that "the sky is round and the place" is reasonable. He obviously didn't expect Xie Shi to be able to pick him out from the crowd, but he didn't know that Xie Shi's five senses were stronger than ordinary people, and his ability to distinguish sounds was also very important. It's easy.

The student surnamed Liang blushed and bravely came out, but he honestly told the sea scene he saw with the telescope yesterday: "Mr. Hui, the students observed yesterday. See hull."

Xie Shi nodded and continued to ask: "The fishing boat set off to the sky just now. In your eyes, did the hull get smaller and smaller until it disappeared?"

The student surnamed Liang replied without hesitation: "Yes, sir." The ship gradually moved away, and to the naked eye, it naturally became smaller and smaller. The student surnamed Liang felt that Xie Shi was asking nonsense. Isn't this obvious? ?

"No." A familiar voice appeared, and when he thanked him, he looked over and saw that it was indeed Han Ning who refuted Liang Sheng. The young man bowed his hands and saluted while thanking Liang Sheng, and then continued: "The scene observed by the student through the telescope is similar to that of Liang Sheng." It’s different. When the students watch the ship going away, it’s not that it changes from big to small and disappears in sight, but that the hull sinks first and disappears in people’s eyes, and then what disappears in people’s eyes is the tall mast on the ship.”

Xie Shi nodded to him, then looked at the other students, and said, "Liang Sheng's first answer and Han Ning's answer just now are the same as the answer I got from the observation. What about the others? Do you have any objections to the observation scene? It can be brought up."

The students at the bottom whispered and whispered to each other. They all carefully recalled the scene observed at the pier last night and just now, and nodded in agreement: "Indeed, sir." Then Xie Shi asked yesterday's question again, "Through last night's Compared with today's 'Gewu', do you still insist that the land we stand on is a continent like a chess game?"

Most of the students looked at each other in blank dismay. How did the fishing boat and the shape of the earth get related?

Xie Shi reminded them: "Assuming that according to the ancients, a place is like a chess game, then what should the returning ships on the sea look like?"

As for Xie Shi's question, Han Ning was still the first one to reply: "Assuming that the place is Fanglu, when the fishing boat returns to the voyage, it should be from far to near, and the boat will appear in the eyes from small to large. When the fishing boat goes out to sea, then On the contrary, whether it is returning or returning, in the eyes of observers, the hull and mast should appear at the same time, without distinction. However, this common sense deduction is the same as what we observed yesterday and today with our own eyes. But it is completely inconsistent. From this, it can be deduced that the conclusion that the land is Fanglu for thousands of years is a big fallacy!"

Facing the rising sun, the young man's voice was deep and calm, but resounding, especially the last sentence, the words "great fallacies" seemed to shock the minds of everyone present, even Qin Sui, who is his wife, was one of them. Vibrate!Is it arrogant for Han Ning to categorically deny the words of the saint?Was he wrong?No, on the contrary, based on what everyone saw with their own eyes, plus the inference, this inference is completely consistent and logical, and cannot be refuted.

If you refute, is it possible that you want to quibble, is that an illusion of the eyes?However, in order for people to see clearly, Mr. Xie Shan even moved the telescope over...

"Papa papa", the clear applause of Xie Shi sounded beside the silent seaside reefs.Xie Shi smiled and said, "Well said! What Han Ning said is exactly what I want to say. To be a scholar, one must have the spirit of daring to challenge authority. Are all the words of the saints right? Not entirely true, the saints again If you are not a god, how can you be without fault? Besides, who said that gods can't make mistakes?"

"If what the sage said is correct, what use is it for us to come later? Just like withered vegetation, birth, old age, sickness and death, everything in the world is not static, but is eternally developing. The same is true for society and human beings. Truth Likewise, the development of truth is a process, and practice is the only criterion for testing truth, and if it cannot stand the test of practice, it is a fallacy."

Xue Sheng, who was standing below, looked serious, and silently recited Xie Shi's words, "The development of truth is a process" and "Practice is the only criterion for testing truth." Enlightening and deafening, what a sage's words!Small words and great righteousness!At this moment, Xue Sheng looked at the calm and bulging Xie Shanzhang on the reef, as if he was watching the sages and sages who were sitting and discussing Taoism, and he felt admiration and admiration spontaneously.

A bomb was left in everyone's hearts, but Xie Shi changed the subject and dropped the second thunder calmly, "Break and then stand, since we've proved that the ground we stand on is not A square continent, so what shape or form should the land be?"

"According to the sight of the ship observed by the naked eye, the earth should be in the shape of an arc, or even a sphere, right sir?" A cold and childish voice appeared to answer Xie Shi's question.Xie Shi raised his eyes and saw a thin and slender young man with an exceptionally handsome appearance and a straight back. When he saw Xie Shi looking over, he was not stage-frightened, but bowed his hands in salute. Xie Shi nodded and smiled, "But Xue Sheng ?”

Xue Sheng obviously didn't expect Xie Shi to recognize him, so he couldn't help being flattered, and respectfully said: "Yes, student Xue Sheng, sir, please enlighten me."

"I heard from Master Qin that you are very talented in mathematics, geometry, and astronomy. I saw you today, and it's true." Xie Shi praised the child who answered the questions correctly, and asked someone to bring the small blackboard and chalk that had been prepared in advance , speak directly on the spot.

Talking about it, some students with poor spatial thinking ability will inevitably find it difficult to understand. Xie Shi used chalk on the special blackboard and drew a few schematic diagrams to aid in understanding.Sure enough, as soon as the picture came out, everyone suddenly realized why Xue Sheng concluded that the earth is an arc or a sphere!Because only these two situations can explain why the hull and mast they observed appeared at different times.

"As for whether it is arc-shaped or spherical? You have to continue to study things to find out." Xie Shi said this, thinking of the famous Magellan's voyage around the world, and made a joke: "If any of us students are interested in exhausting this mystery , you can take a big boat and go straight to the east, and see if it returns to the origin in a circle, or the boat sails to the end of the world and falls." Xie Shi would never have thought at this moment that his joke would make so many people in later history books. A great navigator.

Of course, there is another more famous name recorded in later history books for Xie Shi's lecture, which is called "You Pu Lun Dao" in history. In this lecture, the young Xie Zi completely broke the The theory of "the sky is round and the earth" puts forward the theory that the earth is a sphere, that is, the "earth theory".

Soon, the views revealed by Xie Shi in this shocking lecture spread like wildfire, and quickly spread among the Confucian scholars in the south, and Xie Shi gradually became famous.After that, Xie Shi's "Gezhi Class" was overcrowded. Not only the teachers and students of other classes in the academy came to watch, but also the teachers and students of other academies around and the Confucian scholars in the vicinity came here one after another, just to explore things and gain knowledge Let's talk about it.

For this reason, Dongcang Academy had to arrange Xie Shi's class in a large lecture hall dedicated to lectures by great Confucians, in order to accommodate more and more Confucian scholars who came to listen.

However, when this group of foreign Confucian scholars come, it will be an eye-opener, because Xie Shi's class is completely different from the traditional way of preaching, teaching and dispelling doubts. He can give you a "prism experiment" today to reveal Sunlight is not pure white visible to the naked eye, but seven colors; tomorrow is the so-called chemical experiment, and by the way, some scams will be cracked down...

Knowledge does not come from the scriptures, but from experiments. Xie Shi's unique teaching method not only makes the second-level academy students look forward to Xie Shanzhang's class every day, but even the foreign Confucian students who attend With relish.Of course, the repercussions caused by the novelty of this method are far less intense than the views he obtained through these experiments that violate the world's cognition...
