- "What is scientific spirit?" The little county owner asked without understanding. She had always been very curious about where Zhao Hao's knowledge came from. Naturally, I will not miss this opportunity to understand the whole story.
???????????????????????????????????????????????????? While observing the burning briquettes, each one of them replied:
"It's curiosity, you have to be good at asking questions."
Hearing this, the county chief said to himself that I am very good at this.
¡°It¡¯s about using your imagination to find answers.¡±
The county boss said, I am also good at this.
"It is about respecting evidence. Imagination must be based on objective evidence, not random speculation."
The county leader nodded silently, my imagination is well-founded right?
"It is dialectical thinking, which requires thinking and evaluating the facts seen as a whole and essentially."
"Don't be stubborn. You must actively accept empirical conclusions and actively adjust your own cognition"
¡°It¡¯s about treating failure with tolerance and believing that truth comes from constant trial and error!¡±
After hearing the last three items, Li Mingyue could only stare.
Although she didn¡¯t understand, she applauded vigorously and said, ¡°What you said is so good and so knowledgeable!¡±
But she didn¡¯t dare to ask again, what is the scientific method She was afraid that after listening to it, she would fall asleep on the spot.

After a cup of tea.
Zhao Hao then asked the disciples with a smile: "Tell me what you have observed."
"The color of this fire is different!" Yu Shensi immediately replied: "It is blue! And the fire produced by loose coal is red!"
¡°This is the color when charcoal burns!¡± Li Mingyue quickly added, then looked at Zhao Hao expectantly.
"Yes, I observed it very carefully." Zhao Hao smiled and nodded to show encouragement.
Yu Shensi pursed his lips and said to himself that the master still doesn¡¯t want to see me. It was obviously me who said it, and the county chief added it
"The flames produced by 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.
"After burning for so long, the shape has not changed." Wang Dingjue poked it with a pair of tongs and found a piece of red honeycomb briquettes: "It's quite strong, no wonder there is no soot."
¡°Use your imagination below and guess the reason.¡± Zhao Hao smiled and nodded, signaling to move on to the next step.
Zhao Shizhen responded quickly: "The secret of the blue flame is probably in those small chimney-like eyes of the lotus root. The three points of the fire being mild, the shape not changing, and the soot being small should be due to the addition of yellow mud. As for why It has no taste, because I¡¯ve seen my uncle¡¯s ingredients, so I guess it¡¯s because of the slaked lime.¡±
"Am I right, uncle?" Zhao Shizhen asked confidently after finishing speaking.
Wuyang also looked like he had let you answer first, and he obviously had no objection to his guess.
Zhao Hao nodded with relief, but the corners of his mouth twitched twice unnoticed.
Damn it, I can¡¯t show off anymore
An ordinary person becomes a teacher for a group of geniuses, which saves time and effort but is boring.
Fortunately, besides him, there are two ordinary people here.
Brother and sister Li Chengen and Li Mingyue blinked their eyes after listening to Zhao Shizhen's words, their faces filled with question marks, exclamation marks and ellipses.
"What is all this?" Li Chengen said he didn't understand a word.
"When burning the stove, just pull the bellows, and the fire in the stove will burn brightly and turn the same blue color Don't ask me how I know this? This comes from an experience that the juniors are not envious of." Wang Wuyang explained.
"And charcoal, which also burns blue flames, is the most thorough type of charcoal Don't ask me how I know this? This comes from a long experience that the juniors are not envious of." Hua Shuyang added. : "Therefore, it can be indirectly inferred that good ventilation can ensure complete combustion, and the flame during complete combustion is blue."
"So those little chimney-like lotus root eyes play a role in ventilation!" Li Mingyue suddenly realized.
"Smart" Zhao Hao praised her again, but did not praise his own student.
" Eryang, however, is not as confused as the fifth junior brother They think this is just a sign of their master looking down upon them.
"The reason why the fire is so mild is that yellow mud is added to the pulverized coal to reduce the content of the coalI can tell you how I know, because I pulled the bellows for a certain cook and saw him use this method to control it. The burning of charcoal." Wang Dingjue continued to explain.
¡°When yellow mud is heated, it will become stronger and stronger instead of becoming looser, soThe condition will not change, and there won¡¯t be so much coal ash coming out. "Fourth Senior Brother added.
"As for why hydrated lime can eliminate the smell of soot, this" When it was the fifth junior brother's turn, Yu Shensi got stuck.
He couldn't help but lamented in his heart that it was so unlucky to be the youngest. The brothers had answered all the simple questions, leaving only the most difficult ones.
Yu Shensi could only say weakly: "I'm going to ask the teacher"
Fortunately, none of the senior brothers knew how to do it, so everyone looked at Zhao Hao in unison. "Please teach me, master."
Zhao Hao then replied with a faint smile:
¡°Because the component of hydrated lime is calcium hydroxide, and the choking soot smell comes from sulfur dioxide, when the two react with heat, they will turn into white, odorless calcium sulfate and water.¡±
"" Now let alone the county chief brother and sister, even Wuyang and Zhao are trapped.
"Master, what are they?"
"This is chemistry." Zhao Hao finally found his self-worth and showed off more and more mysteriously:
"Why does coal burn? Why does gunpowder explode? Why does food turn into wine? Why does ironware rust? Wait, wait These secrets are all contained in chemistry. Master chemistry, and you will see another world. , and even became 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 people responded in unison, especially Zhao Shizhen, whose eyes lit up when he heard that he could study explosions.
"Wait until you get the first prize in the examination." Zhao Hao, as expected, pricked the hole. Because in the textbook of "Elementary Chemistry", I didn't write a single word
"Yes, Master!" The three senior brothers responded with high spirits. I thought in my heart that Master is indeed a treasure chest, and I heard a profound knowledge from his mouth.
"My disciple will do his best" Yu Shenxing, who had always been calm as water, also became excited, thinking that this knowledge can be applied as soon as you hear it. I want to learn this!
Even Zhao Shizhen ignited his fighting spirit and secretly vowed to win the top prize as soon as possible in order to have a chance to explode Although he is not even a child student now.
Only the fifth junior brother¡¯s mouth twitched.
Who made him so angry that he vowed never to take the exam again?

"Science Biography*Chemistry Chapter*Prologue*Carbon Fire" records:
¡®In the first month of the second year of Longqing¡¯s reign, more than 100,000 refugees were trapped outside the capital, suffering from difficulties in food and clothing, and mourning everywhere. It happened that my master was supervising all his disciples in spring, and when he saw this, he felt pity. Then use coal 4, soil 1, a little slaked lime, and mix water to make some coal lotus roots. When I tried burning it, I found that there was neither smoke nor pungent smell, which was far better than white coal. It lasts day and night and is more resistant to burning than charcoal.
The disciples looked on in amazement. My master smiled and said, the secret is all in "chemistry". This is the beginning of "chemistry" under the scientific discipline. Thousands of people are interested in the study of chemistry, and it is indeed a supremely good study. My teacher studied heaven and man and benefited the common people, which should be remembered for thousands of years.
Disciple, be careful and respectfully record it. ¡¯
According to the records of "Science Biography * Mechanical Engineering * Chapter 1 * Master Yan Yang":
¡®The original mold for coal lotus root was handmade by Yan Yangzi. When my master saw it, he was very happy and said: ¡®My son, great master, one day the king¡¯s master will be famous overseas, you gave it to him! ¡¯
Yan Yangzi was my disciple. He had not tied up his hair at that time and had dropped out of school since he was a child. My master's skill in understanding people is astonishing, but it is a pity that it has been lost. ¡¯
