Greetings, Mister Principal: Basic elements

"The sandwich is delicious."

Claire could not help but make a sound of pleasure as she felt the rich aroma of gravy between her lips and teeth, as well as the taste enjoyment brought by the mixture of fresh vegetables.

In the end, she still succumbed to the alluring aroma, asked Reiner for a piece of sandwich, and immediately immersed herself in the wonderful food, unable to extricate herself.

But soon, Claire noticed Reiner's thoughtful eyes, and immediately turned away, speaking in a somewhat unclear tone.

"Don't get me wrong, I just wanted to learn how to make this sandwich, so..."

After hearing Claire's lame explanation, Reiner smiled, but did not expose it, and turned to look at Charlotte.

"Charlotte, what do you think of that paper?"

When Charlotte heard Reiner calling her name, she raised her head. She was still holding Reiner's paper in her hand. After thinking for a moment, the girl answered.

“The views stated in the paper are very clear, and the relevant proofs are also very comprehensive. To be honest, I can’t believe that the experiment in this is the one I did before.”

After a pause, the girl continued.

"But there is one thing I don't quite understand, which is the content of the penultimate chapter."

Opening the paper, Charlotte pointed to one of the pages. The title here read "Chapter 4: Exploration of Mass Changes During the Experiment." In this chapter, Reiner focused on the law of conservation of mass. The basic point of view, in Xia Luo's opinion, is really difficult to understand.

Before this, Xia Luo had never considered what would happen to the mass of the object before and after the experiment, nor did she understand the value of the discussion.

Because in her concept, constant quality seems to be a matter of course, but after Reiner mentioned it, Charlotte realized that there seemed to be another mystery.

“Why when one substance changes into another substance after burning, the total mass of the products before and after the reaction does not change. From this experiment, the mass seems to be transferred from the limestone to the white rock and this In a special gas, by what method is this achieved?"

Listening to Xia Luo's question, Reiner nodded slightly.

This girl is really good at alchemy, but she realized the problem so quickly.

"Do you want to say that quality has a carrier?"

Reiner was persuasive and what he said surprised Claire.

In Master Hohenheim’s alchemical theory, mass is an inherent property of an object, which expresses the amount of elements contained in an object. In his view, elements have a unified mass. The more elements an object contains, the more elements it contains. The greater the mass, and the mass of an object per unit volume is called the density.

For example, rocks and metals have different densities because of the amount of earth element. Within a unit volume, there are more earth elements that make up iron, but less earth elements make up rocks. This is the fundamental difference between the two as different substances.

But in Lehner's thesis experiment, part of the mass of the limestone obviously went into the special gas, which seems to involve the transformation of elements. After all, according to common sense, the earth element should be heavy and stable, independent of flow. The light wind element is completely different.

But Master Hohenheim has long asserted that the four basic elements are the most basic composition of objects, and they cannot be transformed into each other. All other substances are condensed from the four basic elements.

If we could really find a way to transform elements into each other, it would be a huge discovery.

Even if running water can be turned into steam after being heated, mages have long understood that those are not real gases, but just small water droplets that cannot be observed with the naked eye. No one has yet been able to achieve the true transformation of elements. .

Looking at it this way, that special gas is a new substance mixed with earth elements and wind elements?

That's weird.

Because Reiner's discussion seems to be saying that the basic elements are not really "basic" and they can be further subdivided, which completely goes against the current alchemical theory.

While Claire was lost in thought, Charlotte shook her head slightly.

"I don't know. I don't think I can find conclusive evidence just by relying on this experiment."

In the final analysis, in the experiment of heating limestone to produce white rock, the material was not completely transformed, nor did something extra appear out of thin air. In the absence of a clear gas composition, it cannot be said that the special gas must be It ran out of the gray rock, and they needed more direct evidence.

Alchemy has always been a subject based on experiments. Any theory may be overturned by special experiments. But on the other hand, if it cannot be reproduced by experiments, then all conjectures will be meaningless.

"I also think that maybe the four basic elements are not the most basic substances, such as water, but may be a combination of certain substances. Of course, these are all conjectures. I may find an opportunity to do some experiments to verify it recently. ”

Reiner pretended to be helpless. Although he had 10,000 ways to prove that water is actually a compound~IndoMTL.com~, it seemed too arrogant to put it forward rashly. After all, the first paper can be said to be based on Xia Luo's experiment was inspired, and it would be suspicious to propose a second subversive paper so soon.

He also needs to wait for his paper to ferment in the academic world, and everyone begins to change their ideas before proceeding step by step. Although there may be surprises, such as a certain academic master relying on Reiner's paper to inspire him, Water broke down the situation, but it was better than having Reiner captured and sliced ​​for study.

"Mr. Principal, do you already have an idea?"

Xia Luo was a little surprised. These questions that they had not dared to think about in the past, the cynical-looking principal in front of her had already begun to think about it. Is he gifted or crazy?

“I don’t have a clue yet, but I have a general direction.”

Leiner decided to end this topic. The first paper has not been published yet, so don't think too long-term.

"Let's not mention this for now, Teacher Claire. I need to leave school tomorrow. You come with me."

"Huh?"

Claire obviously hadn't recovered from the discussion just now. When she heard Reiner calling her name, she answered with some hesitation.

"Where to go?"

"Didn't I say before that we need to find an alchemy workshop that can produce Coke."

Reiner asked rhetorically, looking at Claire with a look of care for the disabled.

"Uh, I, of course I remember, I mean, where are we going to find the alchemy workshop?"

Claire hurriedly concealed it, her embarrassed look was quite endearing.

"Right here."

Pointing to a simple map spread out on the table, Reiner smiled.
