Liu Buqun glanced at Fang Lingjun: "Didn't you find this piece of wood? Although he is very dull, he is indeed good at teaching students."
"Who are you calling dull?" Fang Lingjun was not happy to hear this: "You are such a deviant guy, my father should not have kept you back then!"
"Since sir, you have left me..."
The two senior brothers started arguing with each other.
Jin Feng looked at the two people arguing, and the corners of his mouth turned up involuntarily.
Although the two brothers did not deal with him, Fang Lingjun recognized Liu Buqun's ability before he came, and Liu Buqun did not deliberately belittle Fang Lingjun.
This made Jin Feng's impression of the two senior brothers much better than Tie Shixin's.
The two brothers became more and more quarrelsome. Fang Lingjun was old and out of breath, so he couldn't argue with Liu Buqun. He was so angry that he took off his shoes and slapped Liu Buqun with his hand.
Compared with Fang Lingjun, Liu Buqun is much younger and looks to be in his prime.
If he really takes action, Fang Lingjun will never be Liu Buqun's opponent.
But Liu Buqun shouted loudly, and when he saw his senior brother actually taking action, he was so frightened that he turned around and ran away.
While running, he shouted: "A gentleman talks but never takes action. Third senior brother, you are still a scholar. Why don't you take action if you can't argue?"
"I want to clean up the house for my father!" Fang Lingjun chased after him while holding his shoes.
"What are you doing stupidly, trying to break up a fight!"
Jin Feng kicked Tie Hammer on the butt.
Only then did Tie Zhui step forward and grab Fang Lingjun, still not satisfied: "Mr. Fang, calm down, calm down!"
"Fang Lingjun, if you weren't my senior brother, I would definitely beat you to death!"
Liu Buqun pointed at Fang Lingjun and shouted.
"Say one more thing and try it!" Fang Lingjun waved his shoes, his face flushed with anger.
"Both of you, calm down!"
Jin Feng quickly ran between the two to break up the fight.
"Jin Feng, you brought Fang Lingjun here, are you just watching a joke?" Liu Buqun said angrily.
"Mr. Liu misunderstood, I really want to ask him to teach." Jin Feng said helplessly.
He didn't expect things to develop to this point.
"As far as I know, you only have one school in Xihewan. Isn't it enough that Fang Lingjun has gone there?"
Liu Buqun said: "You go back, I can't stand other people's control, and I can't stand the days when I am the only one who teaches me."
"I am currently preparing a larger school and need more teachers. And I asked Mr. Liu to come over, not to teach liberal arts, but to teach science!" Jin Feng explained. Bayi Chinese website
"Liberal arts? Science?" This was the first time Liu Buqun heard this term.
Even Fang Lingjun put down his shoes and looked at Jin Feng curiously: "Mr. Jin, what is liberal arts and what is science?"
"Mr. Fang, in addition to teaching children reading and literacy, my ideal school would also teach children history, morality and law, geography, physics, chemistry, biology and many other subjects."
Jin Feng explained: “The study of humanities and social subjects, such as literature, history, morality and law, and geography, is the liberal arts.
On the contrary, subjects that study natural origins such as mathematics, physics, chemistry, and biology are called sciences."
Liu Buqun and Fang Ling both knew what literature, history, morality and law meant. Although it was their first time hearing about mathematics, they could understand it. It should be another way of saying arithmetic.
But they have never heard of geography, physics, chemistry and biology, and they don’t know what they mean.
"Geography includes physical geography and human geography. Human geography is to study the customs and characteristics of people in each place, so that we can better integrate with the local people."
Jin Feng explained: “Physical geography studies the texture of mountains, rivers and land. For example, when was this mountain formed? Why are some stones on the mountain red and some gray?
What kind of mountains have mineral deposits, which places are suitable for growing crops, and other issues.
Of course, when there are enough talents in the future, geography can be separated into a branch dedicated to studying climate, such as when will it rain and how long will it rain?"
"Oh my god, this is the study of the great avenue of heaven and earth!" Fang Lingjun was so shocked that his beard stood up.
Liu Buqun's eyes lit up when he heard this, and he continued to ask: "What about physics, chemistry and biology?"
"Physics is simply a subject that studies the structure, interaction and laws of motion of matter."
Jin Feng thought for a moment and pointed to the waterwheel: "For example, why does blacksmithing require fire, and why can water extinguish fire? These are all within the scope of physics research."
"Fire defeats metal, and water defeats fire. It is a matter of course. Do we still need to study this?" Fang Lingjun asked.
"Of course," Jin Feng said: "For example, calcining ore requires a very strong fire. How to make the fire burn more vigorously and make the furnace hotter? There is knowledge in this, and it is also part of the research of physics.
one."
Liu Buqun also came from a family of blacksmiths. His father, grandfather, and even his ancestors had been blacksmiths for several generations. He was more likely to resonate with Jin Feng's words. He nodded repeatedly in agreement when he heard the words.
Then he asked: "What about chemistry and biology?"
"Chemistry is a subject that studies the internal structure of objects and the laws of change. For example, why does iron rust? How to avoid rusting, and how to make iron harder. These are all part of chemical research."
Jin Feng said: "As for biology, it is a subject that studies various animals and plants and analyzes their growth patterns. For example, what structures does wheat consist of, what structures does the human body consist of? What is the function of each organ?"
"This is good, this is good!" After hearing this, Liu Buqun was so excited that he clapped his hands repeatedly.
But Fang Lingjun frowned slightly: "What's the use of studying these heresies?"
"Mr. Fang, it's so useful!"
Jin Feng took out the telescope from his pocket: "This is a telescope made using knowledge of physics. Sir, you can take a look."
Fang Lingjun took the telescope and looked at the distant mountain peaks under Jin Feng's guidance.
"How can it be so clear?" Fang Lingjun was shocked. He put down the telescope and glanced at the mountain peak, then put his eyes under the lens barrel.
The mountain peak is three or four miles long. There is a big pine tree on the top of the mountain. You can only see its outline with the naked eye, but you can see it clearly with a telescope.
"Mr. Fang, this is one of the practical applications of physics."
Jin Feng said: "With a telescope, soldiers can see further during war, discover the enemy earlier, and thus take the lead.
There are many examples like this, such as the crossbow I made, the airship flying in the sky, and the steamship running in the water, all of which used physics knowledge!
Therefore, physical chemistry is not a heresy, it has a very wide range of uses, and if used properly, it can completely change people's lives."
Facts speak louder than words, and the telescope is right in front of him. Fang Lingjun wanted to refute Jin Feng, but he couldn't find a reason.
