Unfortunately, there were no wooden balls in this place. I had no choice but to take them and just let someone take them to replace them. Well, two pieces of cloth, one iron ball, one stone ball, and one copper ball, three spheres of different materials, started the great free fall experiment. The dean personally took the surgery, and more than ten student teachers around me were observers. There were hundreds of people standing down the teaching building.

As a result, well, there were two completely different results. When the cloth piece, cork ball and the other three spheres fell, the cloth piece was floating, which must be later than the other spheres fell. At this time, the thin man standing at the corner of the building seemed extremely proud, but next time, I used the iron ball and stone ball, stone ball and copper ball, copper ball and iron ball to perform free fall, but they all landed at the same time. Suddenly, the students were all stunned and could not understand whether Aristotle's conclusion was correct or wrong.

After completing the previous experiments, I saw that people downstairs and around me were talking, but I still didn’t tell everyone the answer immediately, but instead raised my hand, raised my voice, and explained a truth to these children that truth often takes practice to obtain. However, sometimes, people will doubt the truth, such as now.

"Everyone must have seen that the cloth piece is always later than the fall of all the spheres. Why? Let me tell you, because the air also has resistance. Please see that there are two cloth pieces in my hand, one piece, I will spread it and throw it down, and the other piece, I will knead it into a ball and throw it down."

Very well, the unfolded cloth naturally falls the slowest, and it kneaded into a ball and hits the ground naturally. It will naturally land first. Then, an article was published in the "Tang Dynasty Weekly": cracking the mystery of Western sages throughout the ages, and the Chinese wisdom signed the article. The signatorer was Comrade Li Chunfeng, who was very famous in the Tang Dynasty.

The final conclusion was that there is resistance in the air, and when the air resistance was ignored, balls with different weights fell at the same time when they fell, and the falling speed was not related to the weight. The conclusion drawn from this experiment named this young master the "Law of Free Fall". Also known as Fang's First Law. Hahahaha...

However, after the end of this test, I quickly recruited an emergency meeting for the whole school, requiring students to inform the teacher before conducting a risk test, and after obtaining the teacher's permission, they will only allow it under the guidance of professionals. Otherwise, dangerous tests such as turning into a living person in the academy will be considered as the damage to the academic rules of the academy. In severe cases, I will be relieved. After all, I don't want to kill anyone.

Happy, excited, um. I want to play with the earth, and then the discussion of the law unfolds vigorously. And I have deduced another hypothesis from this: Fang's second law hypothesis. Well, all objects always maintain a uniform linear motion state or a stationary state without any external force until external force forces it to change this state.

On the glass surface, a round glass ball, a leather ball and an iron ball have different rolling distances. Therefore, under the eyes of more than a thousand students and teachers, it is proved that Fang's second law does exist.

Well, these are the laws I have discovered that I have accumulated experience and have discovered. If you have the ability to make Western barbarians flee and ask for patent fees, it would be strange if I don’t beat him up all over the ground. Well, at this moment, I am afraid that Mr. Jia and Mr. Niu’s ancestors are holding their butts naked and ignited to fire, and are learning to draw straight lines and wavy lines in the cave where they live.

According to the academy regulations, various new discoveries, hypotheses and laws must first be approved by the Dianjiang Academy Teaching Committee before they can be published in the Qujiang Tribune, recognized by people, and included in the Whole Directory of Qujiang Academy in the Tang Dynasty. This young master became the first celebrity in the Qujiang Academy in the Tang Dynasty to be listed on the Whole Directory of Qujiang Academy. Well, it finally lived up to my reputation as the first to study things in the Tang Dynasty.

Some scholars from Hongwenguan and Chinese Studies Center whispered a few sour words in the "Datang Daily". However, most capable people and wise people know that the mentality of not being able to eat grapes is just jealous of the achievements made by the Qujiang Academy of the Tang Dynasty.

Therefore, all kinds of magical laws appear in the Qujiang Academy of the Tang Dynasty almost every day, including the law of the turtle not being able to run away from the rabbit, also known as the law of the tortoise and the hare. This is a special evidence used by a student who has nothing to do when he is full and has nothing to do to refute the fable textbook "Tortoise and Hare Race".

Of course, many people will be refuted by the academy teaching committee for no clue, but this also proves one thing: human imagination is endless

But it was just a window for them.

The famous mathematicians, astronomers, physicists, and geometricians of the Tang Dynasty. In short, anyone who stood at the top of various academics was attracted by a series of actions of Qujiang Academy, including Li Chunfeng, PhD student Liang Shu, assistant professor Wang Zhenru and others, who worked in Beijing, were also willing to work part-time in the academy, and specialized in their theory, so as to strive to be famous as soon as possible.

At least after this inexplicable storm, the interest of a large number of students in the academy has changed from focusing entirely on literature to pay attention to specializing in research and learning in other disciplines. I have also invited top talents from all walks of life to give lectures in the academy many times, telling about their problems in work, and then combining them with the content they have learned, so that students gradually realize the benefits of comprehensive development in learning.

Well, at least they have to understand one truth. The mathematics, physics and chemistry they despise in the past were the necessary foundation for human development, and it was also the boost for the Tang Empire to develop the country and the people through science and technology. It also told them that if they are not afraid of learning mathematics, physics and chemistry well and traveling all over the world.

The old man and his mother were almost gone for a long time to smile. At first, the old man felt that his Erlang was crazy and was doing some fallacies all day long. But as a result, it was these fallacies that attracted more and more people to study and work in the academy, which made the old man start to look at these fallacies and evil thoughts in a different way.

"I didn't expect that this academy has become so lively after just over the years. My scholars from the Tang Dynasty regarded it as a place of knowledge. Erlang's ability, as a father, was also inferior to him." The old man took a big sip of wine, glanced at Fang Tai, who was sitting beside him, and smiled and touched the Changsun's head: "Tai'er, learn from your second uncle, don't read the Four Books and Five Classics all day long. You must know that the world is so great that everything changes can be included. Do you understand?"

"The grandson understands that he will definitely live up to grandpa's high expectations." Fang Tai nodded vigorously and replied, sitting properly, like the eldest brother. Oh, a good child, why is he like my eldest brother, not as lively as a young man. Both the mother and the old man are happy, and I am happy, even the third brother is happy, because Fang Tai's return, and because Fang Tai brought good news, the eldest sister-in-law is pregnant again. Because she is afraid that the journey is long, she has to continue to stay in Suzhou for delivery.

"Haha, our Fang family can be considered prosperous. I and my wife have three sons and two daughters. Now, the eldest son not only has a eldest grandson, but his eldest daughter-in-law is pregnant. Erlang, this boy, has four boys and one girl in one breath. In two years, after the third son remarries, our Fang family will finally be able to grow up." The old man was very pleased, and always felt that the more he gave birth, the better the world. Well, in this era, who dares to say that he has less children, even if he is cut into pieces, it is not an exaggeration.

"I'm still young." The third brother said dissatisfiedly, and immediately pointed at his mother: "I'm so embarrassed to say that he is young in front of Tai'er. He is so crazy all day long. He is so big, and he doesn't have a clue yet. Look at your own figure, he is almost as tall as an ordinary person as a 17 or 18-year-old man, and he still says such things in front of his mother all day long."

"Can I blame myself for this head growing fast?" The third brother scratched his scalp in disappointment, looking helpless. "Don't you blame me for anyone? I'm already thirteen. In another two or three years, I will be a family and a career. I don't know how to set up a good example for my nephews. I heard that you are making trouble in the academy again."

"Second brother, how can you slander me?!" The third brother looked very sad and angry. I glanced at the stupid boy. "What's wrong, do you think Second brother, I am such a person? You don't even look at yourself. The clothes on your body are still wet. If something happened, how could you soak your clothes all over your body? And you didn't come back with Second Sister and the others today. Humph! There is no need to blame me for Second brother, you can only blame your mother for her eyes as if she was soaked in her eyes." While attacking the third brother, she also flattered her mother.
Chapter completed!
