Greetings, Mister Principal

Chapter 106: Controlled Variable Method

10.90596, which was much closer to the recognized value compared to the number measured by Reiner initially.

Without speaking, Reiner continued to conduct experiments again with the Borren element in the bottle, and the values obtained basically were all different. It could be determined that the Borren element from the Antojar demiplane was larger than the Borren element in the laboratory and was closer to the recognized value.

"This is weird."

Sharon's eyes were widened in surprise. She repeatedly checked the numbers on the paper, for fear that she had made some mistakes.

Reiner carefully recorded the experimental data, and then took another vial to measure the Borren element from the Gledia demiplane, and the measurement array quickly gave a reading.

10.92779

The difference this time was much bigger than all the previous measurement results.

Subsequently, Reiner used the other two measurement magic circles to make repeated measurements, but the results were almost the same.

"It can be seen that the relative element mass of Borren elements from different regions has different degrees of difference. This does not seem to be an experimental error."

Reiner recorded in his notes that he then took part of the Borren elements from each of the three bottles, mixed them, and began to measure the relative element quality again.

The result this time was 10.90977, which was only 0.00069 away from the accepted value!

Excluding the error in the actual measurement, this could almost be considered equal to the accepted value.

"Why is it like this?"

Sharon sat in the chair, puzzled. It seemed that only the crazy idea of the same element with different masses could explain the problem.

But why?

Why did the same element have different element masses? If this was the case, then it seemed that the arrangement of elements by element mass was not a good idea, and the law of the elements had once again fallen into chaos.

"It seems that when the Rainbow Tower measure the mass of the Borren element, it was closer to 10.91046."

Reiner said. Before this, it was impossible for people to think that the same element would have different element masses, so it was natural to consider the difference as experimental errors.

But his experiments proved that even the same element had a different element mass.

"So isotopes also exist in this world?"

Reiner secretly thought in his mind. Isotope is a common concept on Earth. It refers to the same element with a different mass, which was essentially due to the difference in the number of neutrons contained in the nucleus, resulting in different relative atomic mass.

If isotope existed in this world, then purely relying on relative element mass to arrange the elements would produce inevitable errors. It was no wonder that His Excellency Steinen would be confused by this.

Reiner did not feel the feedback from the world. Based on previous experience and some related studies, it was impossible to get feedback by simply proposing a conjecture as it was now. He must actually find the evidence for the existence of isotope, and at the same time make a systematic summary. Now the experiment of Borren element only indirectly proved that the mass of the elements would be different, but did not find the reason.

To fully prove this idea, Reiner would have to at least find a pure isotope, such as tritium and deuterium.

"This is a bit difficult."

On the one hand, Reiner did not have the financial resources to collect these elements with different masses; on the other hand, the level of magic required to separate the isotopes was far from what he could currently achieve.

In his memory, the separation of isotopes on the earth used the movement of charged particles in a magnetic field, but the magic involved was obviously beyond the reach of the first-ring mage. Unless Reiner could find someone to make these magics into corresponding magic circles. But that must be at least an intermediate level.

Of course, he could write to His Excellency Steinen and tell him his own experiment process. It would be very easy for the legendary mage to create a magic that separates the isotope, but in that case, Reiner would no longer be the first discoverer and the feedback he would obtain from the world would be much less.

As a mage, Reiner naturally had some selfishness.

In the end, he decided to collect information first and try to separate the isotopes. If it was really impossible, he would then seek help from those high-level mages of Mercury Balance.

"We'd better find several other elements that have similar conditions, and make sure that the Borren element is not the only element that has this kind of condition."

Reiner suggested. This could also be evidence for the isotope. Before he had found a way to separate the isotope, these works could also help him analyze.

"Mhm, I will conduct measurement experiments on the elements in the laboratory."

Sharon nodded and said. She felt that she seemed to have touched a certain door, but couldn't step into it. This anxious feeling made her a little restless.

However, a sudden stomach growl made the girl's face flushed.

Reiner smiled and looked out of the window. It was already noon. The two of them had been immersed in the experiment, completely forgetting the time.

"Let's go and eat something first."

Reiner suggested. He himself only ate a piece of bread in the morning, and now he was also a little hungry.

"Mhm."

Sharon nodded vigorously. Compared to Claire, that foodie, Sharon was obviously more restrained, but adolescent girls also needed a lot of nutrition to develop, so they were also interested in eating.

The two packed up the experimental equipment and left the laboratory, but as soon as they walked down the tower, the alchemy creature brought a message.

"A visitor?"

Reiner frowned. There was no appointment recently. He didn't think anyone would come to him at this time, but he still nodded, and then said to Sharon.

"You can go to the canteen first, and I'll see who it is."

"Mhm, okay."

Although Sharon felt a little regretful, she could only nod her head and leave alone.

Reiner walked through the corridor and came to the reception room.

There was a man in a suit sitting here. His face was handsome, his flaxen hair was tied into a ponytail behind him, giving off a little more gentle feeling, and he wore a pair of rimless glasses on the bridge of his nose, making him look like a scholar.

When he saw Reiner, he immediately smiled, stretched out his hand to Reiner, and said.

"Nice to meet you again, Mr. Ian Gray." His voice was a little high-pitched.

"Uh... have we met before?"

Reiner had no impression of the man, and asked some hesitation.

"Haha, I'm sorry, I forgot that this is the first time you saw me in this outfit."

The man immediately untied the ponytail behind his head, took off his glasses, fiddled with it a bit, and said.

"I'm Elise Sophi Net, the owner of Afternoon Tea Party."
