Symbolization of mathematical calculations and expressions, and the alphabetization of chemical equations, are fundamental to the Academy of Sciences. The same is true for the Junior English Academy, where learning begins from the earliest childhood.

Expressing mathematical and chemical ideas in an agreed and standardized form, and expressing information in a condensed form, thereby speeding up mathematical and chemical thinking and promoting the development of related disciplines, is a requirement for scientific development and does not involve any worship of foreign things.

Zhu Youxiao's take-it-or-leave-it approach was to use whatever was convenient for him without giving it much thought. Firstly, it was a matter of habit, and secondly, it was indeed convenient and fast.

Considering the adults' educational level, Zhu Youxiao basically let them study on their own. The textbooks were the same as those used by the Shaoying Academy, and he thought they should learn quickly.

This somewhat permissive approach to education is actually quite acceptable, at least for math. Chemistry, on the other hand, is a rote learning process, relying entirely on individual understanding and comprehension.

There's no way around it. Zhu Youxiao was probably the only one who could explain chemistry so thoroughly. But he was the emperor, so how could he not focus on his duties?

Moreover, he couldn't possibly answer all the questions. For example, the simplest one is, why is carbon C and why is oxygen O? If you can't see or touch something, how can you just say it exists?

Therefore, Zhu Youxiao could only put aside his anxiety and set a three-year plan. Three years is a very short time to build a knowledge system.

Before they had the chance to "punish" Fan Xiaohui in the car, they had already arrived at the Academy of Sciences.

After continuous renovations, the Academy of Sciences was expanded and the gate was renovated. The large plaque was written by Old Dong himself, which is more in line with Zhu Youxiao's aesthetic for famous schools in later generations.

This will be the center of world scientific development. Zhu Youxiao got off the car, looked around, and set another small goal for himself.

Indeed, compared to revitalizing the Ming Dynasty and eliminating its accumulated problems, this task is indeed not too urgent, but rather a long-term vision.

Entering the Academy of Sciences, Zhu Youxiao found that things were different from last time. There were fewer people arguing together, and it seemed quite deserted.

The academy's administrator, knowing the emperor's identity, seemed to see his confusion and hurriedly explained, "Mr. Song is giving a lecture today, and the students are all in the classroom."

Mr. Song?! Song Yingxing!

Zhu Youxiao was stunned for a moment, then guessed that it was Song Yingxing, who was the first to come into contact with chemistry.

Oh, Old Song is not simple. It's only been half a year, and he has upgraded himself to a teacher and opened a forum to teach students! Stop talking nonsense and misleading the students. Are you leading the elites I have selected astray?

Zhu Youxiao asked someone to lead the way and hurried to the classroom, hiding by the door and eavesdropping on Lao Song's lecture.

After listening for a while, Zhu Youxiao couldn't help but smile and was very surprised.

It turned out that Lao Song was talking about Western alchemy and correcting the fallacies in it.

At that time, people believed that gold and silver could be made artificially, that is, by some means, converting base metals such as copper, lead, tin, and iron into precious metals such as gold and silver.

Chinese alchemy and Western alchemy are both the earliest origins of chemistry, and the invention of gunpowder was accidentally obtained from alchemy.

Western alchemy focuses on metals. For example, Greek alchemists melted copper, lead, tin, and iron into an alloy, and then soaked it in a calcium polysulfide solution.

After this reaction, a layer of tin sulfide is formed on the surface of the alloy, and its color is similar to gold. In later generations, the golden tin sulfide was called gold powder and was used as a gold paint on buildings.

Therefore, the alchemist simply believed that "gold" had been refined.

In fact, this method of judging material changes only from the surface color rather than from the essence is self-deception, and mankind has never achieved the goal of "turning stone into gold".

Song Yingxing, from an experimental perspective, concluded that what the alchemists had created was not gold at all. Whether it was cut open, or inferred by weight or density, it was not gold.

Hmm? This seems to use Archimedes' law of buoyancy to prove the difference between so-called "gold" and real gold.

Zhu Youxiao pursed his lips, very satisfied with this.

Needless to say, creating tin sulfide was a great idea! Applying it to palaces and other buildings would create a magnificent display. Let foreigners see how wealthy the Ming Dynasty was.

Although there were some mistakes in Song Yingxing's lectures, Zhu Youxiao believed that the flaws outweighed the merits.

In the history of the development of chemistry, the textbook he compiled is naturally the most correct development history. However, having differences and arguments is not a bad thing.

Lao Song continued to lecture, including his understanding of the lesson. There were pauses in between, and students who raised their hands were asked to ask questions.

The lecture was good, at least there were theories and experiments; the questions were also good, at least not so childish and ridiculous.

Zhu Youxiao smiled and nodded, suddenly feeling that his trip was unnecessary.

The "Martial Arts Secrets" have been given to them, as well as experimental equipment. There is nothing wrong with them making natural progress through their own research and discussion.

Of course, I also need to continue my distance education. Even if I'm just a part of the debate, wouldn't it be more memorable if I let students discern right from wrong and find the truth for themselves?

Thinking of this, Zhu Youxiao smiled faintly, turned around and left quietly without taking away a cloud.

……………………

Zhu Youxiao could slow down the pace of scientific development and progress. After all, the overall level of science and technology in the Ming Dynasty was not the world leader, but it was not behind at all.

The establishment of a scientific and educational system cannot be completed in a short period of time. A dozen years or even several decades would not be too much.

Regardless of how it is implemented, a stable and peaceful social environment is essential. Foreign enemies must be defeated, rebellions must be quelled, and disasters must be overcome.
