Carefree Prince In Tang Dynasty

"The world has its own laws. Flowers bloom and wither, tides ebb and flow, and everything operates based on these laws. Once these laws are mastered by people, they become knowledge, or knowledge." Li Xin said slowly, "Science is the bridge between the two. Through this bridge, people can constantly explore and understand the world, so as to grasp the laws, make use of the laws, and finally even transform the world."

"Although I don't quite understand what you are talking about, I always feel that my heart beats fast when I hear your words." Chen Xinheng smiled, "Could this be the legendary enlightenment?"

Li Xin didn't know where Chen Xinheng was joking, so he could only smile and shake his head for a while.

"However, to be honest, it's hard for me to understand what 'science' is." Chen Xinheng shook his head and said.

Li Xin blinked and asked, "Let me ask you, let go of two small balls at the same height, one light and one heavy, and let them fall freely. Who will hit the ground first?"

Chen Xinheng frowned, showing a puzzled expression, obviously he didn't understand why this question was worth asking. He hesitated for a moment, and seeing Li Xin waiting for an answer very seriously, he finally said, "Of course the heavy ones hit the ground first."

"Really?" Li Xin asked back with a smile, paused and said, "Everything must be questioned first, this is one of the spirits of science."

Chen Xinheng was a little unconcerned, and said, "Such a well-known truth needs to be questioned?"

"Everyone knows that, right?" Li Xin asked with a serious expression, "If everyone knows that the citizens of a certain country have six eyes and eight legs, are the citizens of that country really like that?"

"This..." Chen Xinheng was speechless.

Although he doesn't know what materialism and idealism are, he can more or less understand the important principle that "matter does not depend on people's will".

"If you don't see what the citizens of that country look like with your own eyes, how can you draw conclusions easily?" Li Dao said, "The saints say it casually, and it is the truth that is not easy for all ages. But you and I are not saints, just ordinary people. One must be cautious and cautious before drawing conclusions.”

"Is this also science?" Chen Xinheng asked.

Li Xin nodded and said: "The character of science is prudence." As soon as the words came out of his mouth, he couldn't help being a little embarrassed-these words were so stylish, and they had the potential to be included in the famous sayings. Just imagine, in the future, primary school students will write in their compositions: "Li Xin, a famous thinker, educator, and scientist in the Tang Dynasty, once said that the character of science is prudence."

Well, how should I put it, I always feel a little tasteless. The character of science is also cautious. This seems to be better.

"You speak beautifully." Chen Xinheng couldn't help nodding his head in praise.

Li Xin laughed and said, "Then let's go, let's see together, who will hit the ground first between the two small balls."

Chen Xinheng was noncommittal. The two got up and walked out.

Since he couldn't find the so-called small ball for a while, Li Xin asked a boy in the house to pick up a large and a small stone and run up to the roof. He explained several key points of free fall with words and gestures. The little servant finally stretched his hands forward with half understanding, and let go at the same time.

Under the watchful eyes of Li Xin and Chen Xinheng, two stones, one large and one small, began to fall together.

"Boom!" There was almost only one sound.

Chen Xinheng could hardly believe his ears and eyes. He turned his head and glanced at Li Xin, then turned back to look at the rolling stone, completely clueless about what went wrong, and couldn't say anything at all.

"What's going on? How could this be?" He muttered to himself.

In his world view, it is common sense that heavy things fall to the ground before light ones. But at this moment, what he saw with his own eyes undoubtedly broke this common sense, and by the way, even his worldview was shaken.

Li Xin patted his shoulder, and said slowly: "Instead of asking why these two rocks fell to the ground at the same time, why do you think that the heavier thing will fall to the ground first than the lighter one?"

Chen Xinheng couldn't answer.

"We all accumulate experience from our daily lives and use these experiences to judge things in the outside world. Sometimes these judgments are right, sometimes they are wrong. To a certain extent, science is to separate the false from the true from human experience. After testing "Experience" is no longer just experience, but "learning" and "knowledge".

Li Xin said with a smile.

Chen Xinheng recalled the shock just now, but an uncontrollable smile appeared on his face. That's right, although he still doesn't understand how the magic-like landing at the same time is going on, but he can feel that this is the path he has always wanted to find.

"Then why? Why can two objects of different weights fall to the ground at the same time?" Chen Xinheng asked excitedly.

Li Xin shook his head and said, "It's a long story to say."
