Three consecutive questions, each one is fatal. The disciples of the Imperial Observatory felt their breathing quicken. Establish your mind for heaven and earth, To establish a destiny for the people, To carry on the unique learning to the saints, Create peace for all generations. They have never heard of these four sentences, which may be because they are not well-informed and have a shallow understanding of Confucianism. But even so, I was still infected by the momentum contained in it, and felt my heart surge. If I could really do it, my life in this world would be worthwhile. Why is it that only Confucianism can establish a saint as the most holy teacher? Our Imperial Observatory can do it too!
Everyone is gearing up. In fact, it is normal for them to have such thoughts. Students of natural sciences certainly don't want to be outshined by students of humanities and social sciences. Li Qingcha continued: "Besides, do you really think that ordinary people can't participate in the experiment?" She picked up a porcelain vase and scraped it with her fingers. sizzle- The glaze made a slight sound. Everyone suddenly realized, The glaze on porcelain is made by applying raw materials such as feldspar, borax, and clay on the surface of porcelain, and forming a glassy luster after firing. This is the result of thousands of experiments by craftsmen. Li Qingcha smiled and said, "It is still difficult to popularize experiments now, but the wheel of history is rolling forward, and we cannot hinder the future when everyone can participate in experiments. In this case, the Imperial Observatory should first unify the standards internally. Try to imagine that future generations will record that 'The Imperial Observatory opened the door to a new world for us', that feeling..." "Ugh..." Loud swallowing sounds came one after another. "Sir, please speak!" "In the future, we will do experiments according to what Mr. Li said." "Yes, listen to the sir!" …… The chicken blood was successfully injected. Li Qingcha held back his laughter and continued to experiment while explaining the basic knowledge.
Looking at her serious profile, Luo Weiyang was slightly lost in thought. What a fool this guy is. He should have just given a lecture, but he had to say something shocking like "establishing a model for all ages". The senior brothers and sisters were willing to believe him and followed him to do stupid things. "Could it be that he is more powerful than the master?" the girl murmured to herself. Then, he shook his head again. What am I thinking about! She felt inexplicably irritated, but she didn't feel displeased when she looked at Li Qingcha. Instead, she concentrated on finishing the rest of the experiment. The whole experiment lasted about half an hour, and Li Qingcha finally obtained white floccules from the alum solution. "As long as you follow the steps, there will be no problem." "So that's how it is," Dong Si, who was acting as the assistant, muttered to himself, "My problem lies in the filtering, dissolving, purifying, and the last step, I didn't stir when adding..." Isn't this a problem everywhere? Li Qingcha: ￣□￣｜｜ She clapped her hands and said, "That's it. Chemistry... um... refining is an experimental science. As long as you respect the basic principles and keep exploring, you will always gain something." The disciples of the Imperial Observatory bowed and said, "Thank you for your guidance, sir." "Okay, then I..." "stare--" Everyone's eyes were focused on Li Qingcha. They didn't want Li Qingcha to leave. Li Qingcha was secretly shocked and asked, "Do you have any other questions?" Someone immediately interrupted, "Did Mr. Li talk to Junior Sister about the law of conservation of matter before? We want to hear what it is specifically about." This is hard to explain. Many laws require evolution and accumulation. Without this process, it is like explaining calculus to a child who has just learned 1+1=2. The result of "playing the lute to a cow" is still good, but we are afraid of "only knowing the facts but not the reasons", which will lead to a weak foundation and become a shaky and dangerous building. In the end, the entire natural science building will collapse. For example, the law of conservation of matter was derived because Lavoisier overturned the phlogiston theory through experiments, and this law was then recognized. But in "The Great World", even the phlogiston theory has not been developed yet. Li Qingcha fell into deep thought. a long time, "Let me ask you," she said, "have you ever thought of getting gold from a stone?" This question was so far-fetched that everyone was stunned. The people at the Imperial Observatory did consider the possibility of alchemy, but if the raw materials were stones that could be found everywhere...
"Are you kidding?" Dong Si asked. Li Qingcha looked back at her, his face full of seriousness, obviously not joking. "..." "..." Silence fell over the laboratory. Li Qingcha pointed at the flocculent sediment in the cup and asked, "What are these?" "..." No one answered. Li Qingcha continued: "It's not alum, right?" "..." Still no one answered. Intuitively, everyone present felt that they were experiencing something that was changing the world. This feeling is very ridiculous, but also very real. They held their breath. Li Qingcha said word by word: "The so-called refining is definitely not creating something out of nothing, but a certain degree of replacement. This is the simplest explanation of the law of conservation of matter." Enlightenment. Chapter 17: Heavenly Secret Disk You can hear a pin drop in the laboratory. After a while, "Master Li." "Mr. Li." The disciples of the Imperial Observatory surrounded Li Qingcha again, looking as if they were going to eat her alive. Li Qingcha was depressed. One problem has not yet been solved when another one arises. If this continues, I’m afraid we won’t even have lunch. She winked at Luo Weiyang in the crowd. Luo Weiyang raised her little nose and looked away, pretending she didn't see it, and even mouthed a silent complaint: "I told you to show off! You deserve it." Only women and villains are difficult to raise. The ancients were not lying to me. Li Qingcha was helpless and tried to appease the crowd, "Alright, alright, that's all I can say. As long as you remember the principle of experimentation, you will be able to be like me in the future..."
At this point, he paused, a sharp light flashing in his eyes. A plan formed in my mind. "I can also refine extremely strong colored glass like the Supervisor, which will never break." He changed the subject and began to praise the Supervisor Liuli. At the same time, he scanned the faces of the disciples, trying to detect the slightest changes. Micro-expressions can't lie. The prisoner will definitely be disdainful when he hears "it won't break at all". As a result, no. Isn’t it really not that simple? Li Qingcha couldn't help but shake his head slightly, thinking that he was really meddling in other people's business. The Imperial Observatory had a first-rank official like the Director in charge, so there was no need for him to interfere. She lost interest in continuing the lesson and separated from everyone. "Everyone, it's over. Don't keep me here for dinner." At the same time, walk towards the door. After hearing Li Qingcha's resolute words, the disciples wanted to keep him, but they also knew the etiquette. "Thank you, sir." They bowed deeply to Li Qingcha's back. Looking at this scene, Luo Weiyang was slightly dazed. This was the first time that a disciple of the Imperial Observatory showed such great courtesy to a foreigner. Today's event will go down in history. At this time, "Miss Luo, what are you daydreaming about?" Li Qingcha's voice rang out. Luo Weiyang's face turned red, and she quickly chased after them amid the laughter of her senior brothers and sisters. Two people side by side. Luo Weiyang would steal a glance at Li Qingcha from time to time and go downstairs silently. "Why are you looking at me?" Li Qingcha was puzzled. "Can't watch?" Luo Weiyang asked back. "It's not that you can't watch, but can you please not look at me and act like you want to say something but can't? It makes me care about it too." "(ˉ▽￣~) Cut~~" Luo Weiyang stuck out her tongue cutely. The girl actually didn't know what she was thinking.
She just wanted to look at Li Qingcha and talk to him, no matter what. "Well, then I'll have nothing to say. Don't think I'm annoying." She tilted her head and thought for a while. Suddenly, an idea flashed in her mind and she asked, "Have you ever been exposed to the art of refining before?" "No." Li Qingcha replied. “So that’s innate knowledge?” "Just take it as such." "Prefer not to say?"
