Zhang Shou certainly wouldn't talk about these things when he was in the Imperial College. But now he was in the Outer City Public School. He even gathered people to the Zhang Garden Stargazing Tower to do an iron block falling experiment. He didn't have much scruples about talking about gravity. Moreover, he taught this class to two grades of Jiuzhang Hall together, but he didn't use the already written draft of Physics Volumes 1 and 2.
He would not write so brazenly about the knowledge of gravity, which could easily set off some philosophers.
Although it was explained in the most superficial way and by asking why, for most of the students, what Zhang Shou just said was still an unprecedented shock. Even though Zhang Shou did not completely deny that the sky is round and the earth is square, but assumed that the earth is round and then asked questions, they still felt confused.
Even Ji Jiu, who always considered himself to be very utilitarian and active, almost had his heart stop beating.
Zhang Shou glanced at the students in the classroom and saw that Qi Liang, who had been bombarded with all kinds of questions from him since childhood, also had a confused expression on his face. He suddenly missed Lu Sanlang who was not there because of his wedding leave.
If the little fat guy were here, he might be a calming stream in the muddy waves of confusion. Although he looks fat and wretched, the little fat guy has a strong heart and can probably accept any theory that does not affect his life. Of course, if this theory can make money for the little fat guy, even if the little fat guy says that the water of the Yellow River is flowing up, people will nod their heads unswervingly!
At this time, the class was over. Zhang Shou was about to announce the end of the get out of class, but he found several figures outside. Lu Wan and Liu Zhiyuan were fine, but in addition to Mr. Song who came to announce the test questions in the morning, the King of Jiangdu was also there! Seeing those pale faces, he realized that the superficial knowledge of gravity that he had just instilled in the students was probably heard by them, and he couldn't help but smile.
In the Middle Ages and even during the Renaissance, certain viewpoints would be labeled as heresy. However, in today's Ming Dynasty, the development of navigation has not brought about a scientific revolution. Zhang Shou certainly knew how unorthodox what he had just said was.
But even so, he still calmly announced the end of the get out of class, then walked up to them calmly and greeted them nonchalantly, "Your Majesty, are you here to supervise the exam in person?"
"Yes, there was no trouble at Banshan Hall, but I was sweating profusely while listening to your lecture just now!" King Jiangdu wiped the non-existent cold sweat from his forehead, then shook his head and said, "I really admire my brother. It is probably because of an emperor as independent as him that he dares to employ a rebellious hero like you, Master Zhang."
"Thank you, Your Majesty, for not telling the truth. I was just spreading rumors to confuse the public." Zhang Shou laughed and saw that Lu Wan was sighing. Although Liu Zhiyuan frowned, he did not show obvious anger. Mr. Song had a confused and stupid look on his face. He thought that the academic environment here was indeed much better than that of the Imperial College, so he calmly recited a poem.
"In the beginning of ancient times, who taught it? How could we examine it when the world was not yet formed? Who could understand the darkness? How could we know the image? What happened at that time…"
He casually recited Qu Yuan's famous "Heavenly Questions", and stopped after reading about a dozen questions. Then he smiled and said: "Qu Yuan's "Heavenly Questions" is full of thoughts, but it was not until a thousand years later that Liu Zihou's "Heavenly Dui" was written. Most people think that "Heavenly Dui" is just a direct expression of one's feelings by using the yin and yang of heaven and earth, and has no practical meaning, so they discard it like a worn-out shoe."
