Greetings, Mister Principal: Controlled variable method

10.90596, which is different from the recognized relative element mass of 10.91046 of the Beuran element by three decimal places, and the difference from the relative element mass of 10.88927 originally measured by Reiner is two decimal places. In comparison, it is closer to the recognized value. .

Without saying a word, Reiner continued to conduct three experiments with the Borron element in this bottle. The values ​​obtained basically hovered around the first one. It can be determined that the Borron from the demiplane of Antohal The relative elemental mass of the element is larger than that of the Bollon elements in the laboratory, and is closer to the accepted value.

"This is so weird."

Xia Luo's eyes widened in surprise, and she repeatedly checked the numbers on the paper, fearing that she had seen the wrong one.

Reiner carefully recorded the experimental data, and then took another vial of the Bollen element from the demiplane of Gladia for measurement, and the measurement array quickly gave a reading.

10.92779!

This is within two decimal places of the accepted value, and is much larger than all measurements.

Subsequently, Reiner used two other measurement arrays to conduct repeated measurements many times, but the results were almost the same.

“It can be seen that the relative elemental masses of Bollen elements from different regions are different to varying degrees. This does not seem to be an experimental error.”

Reiner recorded in his notes that he then took a portion of the Bolen elements from each of the three bottles, mixed them and began to measure the relative element mass again.

This time the result is 10.90977, which is only 0.00069 away from the accepted value!

Excluding errors in actual measurements, this can almost be considered equal to the recognized value.

"Why is this happening?"

Xia Luo sat on the chair, puzzled. Now it seems that only the crazy idea that the same element has different qualities can explain this problem.

But why?

Why does the same element have different elemental qualities? If this is the case, then arranging elements based on elemental quality seems less convincing, and the laws of elements have once again fallen into mystery.

"It seems that during previous measurements, the elemental mass of the Bollen element used in Rainbow Tower was closer to 10.91046."

Leiner said that before this, it was impossible for people to think that the same element would have different elemental masses, so it was natural to regard some measurement values ​​that were too different from the generally accepted values ​​as experimental errors and discard them.

But his experiments proved that even the same element has different elemental masses.

"Are there really isotopes?"

Reiner secretly thought in his mind that isotopes are a common concept on earth, referring to the same element with different elemental masses. The essential reason for its appearance is the difference in the number of neutrons contained in the atomic nucleus, resulting in relative Atomic masses vary.

If there are really isotopes, then simply relying on the relative element mass to arrange the elements will produce inevitable errors. No wonder Lord Stanion is confused by this.

Reiner did not feel the feedback from the world. Based on previous experience and some related research, it is impossible to get feedback by simply proposing a conjecture like this. He must actually find evidence of the existence of isotopes and conduct systematic induction at the same time. In summary, the current experiment with Bollen elements only indirectly proves that the masses of elements are different, but does not find the reason.

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

"This is a bit difficult to handle."

On the one hand, Reiner does not have the financial resources to collect these elements with different qualities like a needle in a haystack. On the other hand, the level of magic required to separate isotopes is far beyond what he can currently achieve.

In my memory, the separation of isotopes on the earth uses the movement of charged particles in a magnetic field, but the magic involved is obviously beyond the reach of a first-circle mage, unless Reiner finds someone to make these magics into corresponding A magic circle, but it must be at least an intermediate level.

Of course he can write to Lord Stanion and tell him about his experimental process. It must be not simple for the legendary mage to create a magic that separates isotopes, but in that case, Reiner will no longer be the first discoverer. , the feedback that can be obtained is much less.

As a mage, Reiner naturally has some selfish motives.

In the end, he decided to collect information first and try to separate the isotopes. If he couldn't do it, he would turn to the high-level mages of Mercury Balance and sell his favors.

"We'd better find several other elements with similar situations to make sure that this is not a unique situation of the Bollon element."

Reiner suggested that this was also evidence to support isotopes. Before he found a way to separate isotopes, these works could also help him analyze.

"Well, I have been conducting measurement experiments on the elements in the laboratory during this period."

Xia Luo nodded. She felt that she seemed to have touched a certain door, but could not step into it. This anxious feeling made her a little upset.

Gu——

However, an inappropriate stomach growl made the girl's face turn red.

Reiner smiled and looked up out of the window. It was already noon. The two of them were immersed in the experiment and forgot about time. The morning passed like this.

“Let’s go get something to eat~IndoMTL.com~Xia Luo.”

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

"Yeah."

Charlotte nodded vigorously. Compared to Claire's obsessive eating, Charlotte was obviously not that exaggerated. However, adolescent girls also need a lot of nutrients to grow, so they are also very interested in eating.

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

"Is someone coming to visit me?"

Reiner frowned. He had not made any reservations recently. He could not imagine that anyone would come to him at this time. However, Reiner nodded and then said to Charlotte.

"Then Xia Luo, go to the cafeteria first, and I'll go see who it is."

"Yeah, okay."

Although Xia Luo felt a little regretful, she could only nod in agreement and leave alone.

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

A man wearing a suit is sitting here. He has a delicate and handsome face. His flaxen shawl hair is tied into a ponytail behind his back, giving him a gentler feeling. He wears a pair of rimless glasses on the bridge of his nose. Quite a scholar's temperament.

When he saw Reiner, he immediately smiled, stretched out his hand to Reiner, and spoke in a shrill voice.

"Long time no see, Mr. Ian Gray."

"Uh... do we know each other?"

Reiner had no impression of this man and asked hesitantly.

"Haha, sorry, I forgot, Mr. Iain Gray, this is the first time you see me dressed like this."

The man then untied the ponytail on the back of his head, took off his glasses, played with them a little, and then said.

"I am Elise Sophienit, the manager of the Afternoon Tea Party."
