Fengming Academy rarely has caused such sensation as it is today. Early in the morning, the stepped classrooms were filled with people, including outstanding student representatives such as Zhao Ji, Mu Xijing and Wu Zhuan; there are also people like Gongzi Shaoguan who often provoke various disputes and persist in bringing vitality to the academy; on the main podium, there were also teachers such as Master Yan, Master Meng, Yang Zhu and Yangzi.

Even Wei Yang, who was busy with secondary reforms, came. Bai Dong's appearance made his journey of reforms surprisingly smooth. Some of the difficulties and setbacks that should have occurred did not appear. Now he started the secondary reforms at least ten years earlier than in history. Although the specific terms are still being determined, most of them have received the support of Ying Quliang and Bai Dong, and with the three families of Meng Xibai, even if someone would object, it was mostly just a matter of saying the law and would not cause chaos that shocked the whole country.

Is this dean determined to stick to his side theory? Mr. Yan Jian, Master Meng and others who were sitting on the side of the podium looked at the students who were talking, and they felt a little nervous. Even Yang Zhu, who had always been brave enough to accept the new theory, had a serious expression on his face.

Bai Dong's "Tianxing Class" launched three months ago is really too novel, completely different from the previous sci-science and mathematics. Although those knowledge are also relatively novel, they are not ignorant of them. Some of the views and theories of sci-science are inherently interrelated with the theories of the hundred schools of thought, and they also have the meaning of mediocrity. Not to mention math, there is a number of ways in the six arts of gentlemen. Confucianism is not unfamiliar with the craftsmen, and they are even more proficient in them, so they do not feel rejected.

But what is the knowledge about the star-shaking technique mentioned in this Tianxing class? It is true that there was a Sixing school since the Shang Dynasty. Another person named Wu Xian also wrote the "Wu Xian Xing Sutra", but it is something that mediocre people entrusted to heaven and earth to confuse the king and the people. For example, which other countries in the following countries will appoint a Sixing official? There is no such thing at all! It can be seen that this is not the right way to learn, so it cannot be listed among the hundreds of schools for a long time. The dignified president of Fengming Academy and the world-famous Bai Zi suddenly wanted to list this course? Shouldn't he go crazy after going to Qi?

The incident of Tian Ji's horse racing has now been faintly revealed. Everyone didn't know that Tian Yinqi had bet on the position of the main school of Jixia Academy for this, but he thought that Bai Dong was not allowed to defend himself when he became famous at a young age, and began to become frivolous. Gambling on horse racing? This is not what Liezi of the generation of scholars should do.

To defeat the enemy, you must first understand the enemy. So on the day Bai Dong started the class, the first one to run was Mr. Yan, who was the most fiercely opposed. Unfortunately, most of the students who chose "Star Class" were interested in mathematics. Except for outstanding students like Wu Zhuan and Mu Xijing, half of them were girls. It was too eye-catching for him, a white-haired old guy, who hid in the group of girls. As a result, Bai Dong respectfully invited him to the main podium to listen to the lecture. His companions were also Master Meng and others and fleas who came to cheer for his husband.

It turns out that people have different heights when standing on the ground? If you contact the sun, moon, stars and the center of the earth, you can get a degree? The maximum is only ninety degrees, so what else can you tell the north and south latitudes? After all, Master Yan is a scholar of a generation. After listening to several lessons, it is naturally not difficult to understand what this latitude means with his arithmetic ability. Although the latitude cannot be completely equivalent to the height he understands, he can still imagine that it is very useful if this thing is used to determine locations on a vast grassland or sea. Although the Chinese also have various means to determine directions and directions, Bai Dong is really the first one.

Old Yan Jian, who barely accepted the technique of star-shaking, secretly asked for a few star-shaking boards from Gongshuzhi, and ran to various places to experience it with several masters. He found that Bai Dong was indeed not lying. The degree obtained by standing in the academy at night and running to the mountain to measure the "Beichen Star". However, the maximum dimension is only 90 degrees, which seems to be not enough to determine the direction, right? This is the question raised by the old master after he devoted himself to researching it. You must also let you know that Master is also a smart person and can easily find out the flaws of this science!

Bai Dong quickly gave an answer, "The orientation cannot be accurately determined based on latitude alone. Even if it is possible in a small range, it will become inaccurate enough when it reaches a larger area, so we must determine the location based on longitude. The sun, moon and stars have been used by us to measure latitude, so to measure longitude, we must reset a source point, its name is the prime meridian'

In fact, even if you don’t tell the true appearance of the earth, Bai Dong can also propose the concept of “primary meridian” in some deceptive language; Lao Yan Jian and others have never even made a Chinese version, and it is too difficult to expect them to expose this lie. But Bai Dong cannot afford to lose this person, because with the concept of longitude and longitude and longitude, with the gradual popularization of the white shipbuilding method, the world will set off a sailing trend in the next hundred years. If hundreds of years pass, when people find that the earth is actually round, will they be written into geography textbooks as a negative example?

I remember that when I was a student, the most common and most tragic person in the textbook was Mr. Aristotle, a wise man. He was obviously the greatest scholar in ancient Greece, but because of historical limitations, he was pulled out again and again to become a representative figure of the "error theory". When Bai Dong was young, he once thought that Aristotle was a failed guy, but he didn't know that he was as great as Archimedes, Newton, Edison, and Einstein.

This kind of tragedy must never happen to him, so from the beginning, Bai Dong had to put forward the most correct view, break the theory of the sky and the earth, and establish his own "sphere" theory. Qin State was not an ancient Europe. Bai Zi, who was powerful in Qin, had time to explain and prove his views, and he didn't have to worry about being sent to the stolen rack like Bruno.

"The world we are in is a sphere. It is like all circular objects, with two 'centric centers' at the top and a 'circumference' at the largest circumference. So no matter where we draw a line on this sphere, it will return to this point again, and this line can be called the 'primary meridian'. What if there are more lines like this? We can see that there is an extra 'fishing net' on this sphere, with countless grids, and the distance between the grid is the 'longitude'. With this longitude created by man and combined with the dimensions derived from star-drawing techniques, any position can be easily determined."

Bai Dong had already used languages ​​that Lao Yan Jian and others could understand to describe the 'Benqiu meridian' and 'longitude'. In order to be more vivid and vivid, he even asked the Gongshu to make a wooden ball and drew a series of meridians on the ball by himself: "The Benqiu meridian can actually be fixed in any place, such as the royal palace of the Zhou royal family, the Liang of the Wei Kingdom, and even a small bamboo building in Shu Kingdom. But I was still going to set it in Lao Qin, so let him pass through the palace where the king lived. At that time, the world would have to use our Lao Qin as the source point to calculate the longitude they were in."

This person is completely crazy!

Lao Yan Jian and others were stunned. Even Xu Zi, a farmer who was very acknowledged by the invention of Quyuan Li, glared at Bai Dong in surprise and looked at Bai Dong like a monster. Yang Zhu slapped Wei Yang on the thigh beside him. He wanted to stand up and cheer, but Wei Yang pulled him to the seat. This kid is really amazing. He deserves to be a person who wants to be inferior to me. He actually said that the world we live in is a ball? His aunt, if this world is a ball, how can the endless Guanzhong Plain be explained? Why don’t I go out and roll all the way? The old Qin people stood on this ball and didn’t fall down, then wouldn’t the Wei people have to fall down? Not to mention the Chu people, it’s very interesting. This kind of strange and strange theory is my favorite.

He was afraid that the world would not be in chaos, but Old Yan Jian was so angry that he was trembling. He could barely accept the concept of star-locking art and latitude because Bai Dong's foundation was not separated from the avatar of scholars. After all, the art of star-gazing was also something passed down from the Shang Dynasty. Although it was not included in the eyes of the hundreds of schools, it was considered a science.

It is too incredible to say that the world is a ball. If you want to set up the prime meridian, you want to set up the original meridian. If you want to set up the Qin State, you want to set it up. If you want to set it up, you will be in Qin State. Who asked you to put it up? But what does this have to do with whether the world is square or round? Is this a propaganda of fallacies and evil deeds? Is the dignified Fengming Academy going to the sidelines?

Lao Yan Jian must object. In his opinion, this is no longer a matter of academic division, but a matter of principle. When dealing with such fallacies, hundreds of schools of thought should attack each other so that this kid can be sober.

Academic wars are sometimes more terrifying than the real battlefield. Old Yan Jian didn't care about Bai Dong's face and immediately slapped the table. Fortunately, Meng Ke was caught by Meng Ke. Meng Ke was not more cultivated than him, but he got news from Tian Yinqi in private, knowing that Tian Yinqi would support Bai Dong as the head of Jixia Academy in the future. Since this kid had such a rare opportunity, how could he be defamed for no reason? Since he said that this world is a ball, there must be a reason. You might as well listen first.

Compared with the Masters, the students in the audience were more intense. The young master laughed the most, and he was so angry that he even abandoned the mission of defending the Bai family brother; some female students exclaimed in surprise and covered their lips. They couldn't figure out how the young, handsome, talented and knowledgeable Bai Zi suddenly said such words; only Wu Zhuan's eyes suddenly lit up, and he stared at Bai Dong tightly, hoping that Bai Dong would continue to say it as soon as possible; Mu Xijing and Zhao Ji were both the best among the students, but they were frowning and thinking hard, and it was difficult to understand Bai Dong's words for a while.
