What is the spirit of science? The little county lord asked if she didn't understand, she had always been very curious, where did Zhao Hao's knowledge come from. Naturally, I will not miss this opportunity to understand the reason

Wuyang Yizhao observed the burning honeycomb coal, and replied one by one:

"It's curiosity, it's good at asking questions."

When the county lord heard this, he said in his heart that I can do this.

"It's about using your imagination to find answers."

The county lord said, I'm also good at this.

"It's about respecting the evidence. Imagination must be based on objective evidence, not speculation. ”

The county lord nodded silently, my imagination is all grounded...... Right?

"It is dialectical thinking, thinking and evaluating the facts seen in the whole and in essence."

"It's not opinionated. We should take the initiative to accept empirical conclusions and actively adjust our cognitive ......"

"It is to be tolerant of failure, and to believe that the truth comes from continuous trial and error!"

Hearing the last three, Li Mingyue could only stare dryly.

Although she didn't know, she applauded vigorously: "It's so good, it's too learned!" ”

But I don't dare to ask anymore, what is the scientific method...... She was afraid that she would fall asleep on the spot when she finished listening.

After the tea effort.

Zhao Hao smiled and asked the disciples, "Tell me what you have observed." ”

"The color of this fire is different!" Yu Shensi immediately replied: "It's blue!" And the fire that comes out of loose coal is red! ”

"That's the color of charcoal when it burns!" Li Mingyue hurriedly added, and then looked at Zhao Hao expectantly.

"Yes, very carefully." Zhao Hao nodded with a smile to show encouragement.

Yu Shensi pursed his mouth, and said in his heart that the master still doesn't want to see me, obviously I said it, and the county lord added it......

"The flames from this coal lotus root are small and soft, not as fierce as those two charcoal pots." Zhao Shizhen added.

"What else?" Zhao Hao asked again.

"It's been burned for so long, and the shape hasn't changed." Wang Dingjue poked it with fire tongs, and said with a piece of red honeycomb coal: "It's quite strong, no wonder there is no soot." ”

"Let your imagination run wild and guess why." Zhao Hao smiled and nodded, signaling to enter the next link.

Zhao Shizhen replied: "The secret of the blue flame is probably in those small chimney-like lotus eyes; The fire is mild, the shape has not changed, and the coal ash is small, which should be due to the yellow mud; As for why there is no taste, I have seen my uncle's ingredients, so I guess it is the reason for the slaked lime. ”

"Am I right, uncle?" After Zhao Shizhen finished speaking, he asked confidently.

Wuyang also looked like he let the kid answer first, obviously having no objection to his guess.

Zhao Hao nodded with a relieved face, but the corners of his mouth twitched twice imperceptibly.

He's meowing, and my son can't show it off......

An ordinary person becomes a teacher for a group of geniuses, which saves time and effort but is boring.

Fortunately, in addition to him, there are two ordinary people here.

Brother and sister Li Chengen and Li Mingyue listened to Zhao Shizhen's words with blinking, and their faces were full of question marks, exclamation marks and ellipses.

"What is this?" Li Chengen said that he didn't understand a word.

"When the stove is burning, as long as you pull the bellows, the fire in the stove will burn brightly, and it will be the same blue...... Don't ask me how I know? This comes from an experience that the juniors and disciples can't envy. Wang Wuyang explained.

"And charcoal, which also burns blue flames, is the most thorough kind of charcoal...... Don't ask me how I know? This comes from a long experience that the juniors and disciples can't envy. Hua Shuyang added: "Therefore, it can be indirectly inferred that good ventilation can make the combustion complete, and the flame when it is completely burned is blue." ”

"So those little chimney-like lotus eyes play a role in ventilation!" Li Mingyue suddenly realized.

"Smart ......" Zhao Hao praised her again, but did not praise his students.

Eryang wouldn't be as unthinkable as the fifth junior brother...... They thought that this was just a sign that the Master looked up to them.

"The reason for the mild fire is that the yellow mud is mixed into the pulverized coal, which reduces the coal content...... I can tell you how I know, because I pulled the bellows for a certain cook and saw him use this method to control the burning of charcoal. Wang Dingjue then explained.

"When the yellow mud is heated, it gets stronger and stronger, not more and more scattered, so the shape doesn't change, and there won't be as much soot coming out." The fourth senior brother added.

"As for why slaked lime eliminates the smell of soot, this ......" When it was the turn of the fifth junior brother, Yu Shensi was stuck.

He couldn't help but complain in his heart, it was too unlucky to be the old man, and the senior brothers answered all the simple questions, leaving only the most difficult ones.

Yu Shensi had no choice but to say weakly: "I'm going to invite the teacher......

Fortunately, the senior brothers didn't know either, so everyone looked at Zhao Hao together. "Please give me advice."

Zhao Hao replied with a faint smile:

"Because the composition of slaked lime is calcium hydroxide, and the choking soot smell comes from sulfur dioxide, when the two react with heat, they will turn into white and odorless calcium sulfate and water."

"......" Don't talk about the county lord's brothers and sisters now, even Wuyang and Zhao are all circled.

"Master, what is that?"

"It's chemistry." This made Zhao Hao finally regain his self-worth, and said more and more mysteriously:

"Why does coal burn? Why does gunpowder explode? Why is food turned into wine? Why do iron tools rust? And so on and so forth...... These secrets are contained in chemistry, and if you master chemistry, you will see another world, and even become a god in the eyes of the world. ”

After a pause, he looked at the students with a smile and said, "Do you want to learn?" ”

"I want to learn!" The six of them responded in unison, especially Zhao Shizhen, when he heard that he could study the explosion, his eyes lit up.

"Wait until you get the top spot in the exam." Zhao Hao unexpectedly stuck his mouth. Because of the textbook of "Elementary Chemistry", Ben Gongzi didn't write a word......

"Yes, Master!" The three senior brothers responded with high morale. The heart said that the master was indeed a treasure chest, and from his old man's mouth, he heard a profound knowledge.

"The apprentice will try his best to ......" Yu Shenxing, who has been quiet like water, also became excited, and said in his heart that this knowledge can be applied as soon as he hears it, I want to learn this!

Even Zhao Shizhen also ignited his fighting spirit, and secretly vowed to strive for the top prize as soon as possible in order to have a chance to explode...... Although now, he is not even a child.

Only the corners of the fifth junior brother's mouth twitched.

Who made him so angry at the beginning that he swore that he would never take the test again?

Regret the green intestines......

"Science Biography * Chemistry * Prologue * Carboniferous Fire records:

In the first month of the second year of Longqing, more than 100,000 displaced people lived outside Beijing, with food and clothing and grief all over the country. It coincided with the spring of my master and the disciples of the Governor, and I felt pity when I saw this. Then four coal, one soil, a little slaked lime, and a little water were transferred to make a number of coal roots. The test burning, there is neither smoke and dust, nor pungent gas, far better than white coal. And it does not disappear day and night, and is more resistant to burning than charcoal.

The disciples were amazed, and my teacher smiled and said, this mystery is all in 'chemistry', which is the beginning of "chemistry" under the science gate. The study of chemistry is a great science. My teacher is a scholar of heaven and man, and Ze is born by the common people, and it should be remembered for thousands of years.

The disciple is cautious and respectful. ’

In addition, according to the "Science Biography * Mechanical Engineering * Chapter 1 * Giant Yanyang" records:

'The initial mold of the coal lotus root was handmade by Yanyangzi, and my master was overjoyed to see it and said: 'My son is a great master, he is a great master of the king, and you have given it!' ’

Yanyangzi is my teacher and son, and he has not tied his hair and dropped out of school since he was a child. My master's skill of knowing people is miraculous, but it is a pity that it has been lost. ’
