With the help of Gotar Taling, the magicians who arrived first opened the closed doors, so that the scene in the room was clearly seen by Samantha and Rachel.

This is a fresh and clean study room. Each book is neatly arranged without any confusion. The paper on the table is divided into several piles in an orderly manner. Even the draft paper is meticulously stacked on top of each other. Every corner of the details fully reflects the owner Harvin's strict and serious to morbid compulsion.

On the chair behind the desk, Harvin sat quietly, and a layer of translucent ice crystals condensed on his body. Even in the temperature of July, they did not melt much, but turned the surrounding air into white. Frost.

Haven in the ice cube sits very straight, dressed as a standard tower magician wearing a gray pointed hat and wide robe, and in combination with badges such as arcane on the chest, solemnly like to participate in the "Evans Arcane Award" or The award ceremony of the Arcane Scepter.

His face was pale, his expression stiffened with a touch of confusion, despair, and relief, and with a glass of red wine in his hand, as if standing up to welcome everyone at any time, but his eyes were empty and not a little angry.

"This is really the death method Havin will choose, clean and fresh, full of grace ..." Rachel whispered to Samantha.

They both knew Harvin. After all, they were also arcane masters with high towers who hoped to advance to the sixth ring. They competed and inspired each other, and the relationship was quite harmonious. Therefore, they also know Harvard's character better, but now The two of them were already high-level arcanists and magicians, but Havin ended his life with ice and snow magic. This has to be said to be two microcosms of the times.

Samantha thought of her wandering, confusion and frustration since this period of time, and she said, "In fact, in another ten years, Harvin can be promoted to higher levels ... In fact, no matter how desperate, you should not give up lightly. It's me, I will live, live well, see what the arcane world will look like, and see if it is worth our loss ... "

"Harvard has severe obsessive-compulsive disorder and depression. I have been trying to build a corresponding hormone magic to help him. Unfortunately ..." Rachel said to himself, his teacher, and Lucian Evans. concept.

In the past. Although this psychological problem can be dealt with by magic, it is only a short-term effect, such as using mechanized mind and other spells, unless a magician is willing to abandon normal feelings. Permanently resembles magic. Can be considered a "complete solution". Therefore, there are not a few extreme or crazy characters in ancient magicians!

Samantha is no stranger to psychological arcane development because of her good friends. Slightly nodded: "In addition to the help of magic, daily enlightenment is needed, but the basic theory of psychotherapy has always been lacking, and it is impossible to consolidate the researched bits and pieces into a complete system."

During the conversation, the two walked into Harvin's room as Harvin's friend and a high-level magician. The rest of the Arcanists defaulted their authority to handle this matter.

Thanks to Harvin's "good habits", Rachel and Samantha did not spend much time searching, and simply found an unsealed letter at the corresponding position on the desk.

The patterned paper in the letter was scented with a slight scroll and folded into a square shape.

Rachel didn't care, opened the stationery after careful inspection, and read the content softly:

"... The arguments of the past period have exhausted me. I cannot imagine that the basis of the entire astrological system will be overturned. No, it is the loss of certainty of the entire physical world ... Development is in the opposite direction ... "

"... Recalling the rapid development of arcane art in the past few years, I deeply feel confused. The things we are afraid, afraid and desperately resisting today are just the products of the theory we were pleased with and satisfied with. How ridiculous ... "

"... My brain is constantly thinking about all kinds of difficult and even contradictory problems. No one second can get quiet, but my thinking cannot solve any dilemma. I am tired, tired, and want to end this. life……"

"... I made a decision weakly. I don't think I can catch up with the development of arcane art. I also can't accept such development. I hope to return to the golden age of determinism in my dream ..."

After reading this letter, full of exhaustion, despair and blankness, Rachel suddenly felt a little bit empathetic. Except for the few, most arcanists probably had similar feelings, only in different degrees.

"Haven ... hmm ..." She wanted to say something, but it turned into a sigh.

All the magicians who came came to silence, as if mourning for Havin and being sad for themselves.

Samantha retracted her eyes from Havin's body and looked out of the window. The sun at noon in July was so brilliant, but so dazzling.

As time passed, Rachel cleared her throat and prepared to arrange the next thing. At this moment, a tower magician came up from the elevator with a thick book in his hand: "Issued Special issue! "

His voice was with obvious joy, and a brief glance seemed to make him see a structured mathematical hall.

"?" Samantha asked subconsciously.

The tower magician replied with joy and a loud voice: "Yes, His Excellency's answers to many current mathematical problems. With these answers, he has built a dense and solid mathematical system!"

He could only answer this because he had to read it carefully in the future. Suddenly, he found the situation in the study: "Ha, what happened to Havin?"

Another magician told him briefly about the story and Havin's last words. He was annoyed and regretfully said: "I should have come up earlier. If Havin saw this book, he would certainly reignite the enthusiasm for mathematical studies. Some time ago, I had similar confusion and frustration, but now. These emotions can't quench my enthusiasm for mathematics and physics, we have so many things worth doing! "

Samantha and Rachel were exaggerating when he heard what he said. They couldn't help but read the books they bought in his storage bag and read them directly in Harvin's study.

Although there is no time to look at the specific derivation process, just suggesting or redefining some concepts in the mathematical fields such as logistic theory, set, group, field, topology, etc., makes them refreshed, it seems that scattered and random research in the past Formed an inseparable whole, flesh and blood connected.

Much of the content of this book does not exceed their knowledge, because it is based on current research in the field of mathematics and physics, and is integrated and further elucidated. The new concepts proposed are not very difficult to understand. Not only does it have a rigorous logical deduction process, but it also happens to hit the difficulties encountered by the current high tower arcanist.

Looking at this book, Samantha, Rachel, and others seem to see the formation of new directions in the field of mathematics and physics, and see an extremely wide world!

"In the past, His Excellency Evans often said. Mathematics cannot rely on arcane and magic. It cannot only serve to solve their problems. It should be an independent theory based on rigorous deduction and deduction. It has its own problems and cannot be attributed to Don't pay attention to them if you don't need them, "Rachel suddenly said with emotion. "I remember these words very clearly and felt very reasonable, but in actual research, I still ignore a lot of problems. Now, I fully understand the meaning."

She swept away the sorrow, confusion, and confusion before, looking quite angry, and seemed to rekindle her passion.

Samantha also felt very authentic: "In the past, when applying scattered mathematical knowledge to solve problems, although it eventually achieved its purpose, it always felt very obscure and difficult. It seems that invisible walls around it are blocking our efforts, and Now those walls are gone ... "

"Well, His Excellency Evans also made an in-depth explanation of axiomatization, and gave a complete axiomatic system of tower geometry." An arcanist said the latter part, although Lucian had proposed the axiom early The concept of transformation has also been studied and applied by some arcanists in practice, but after seeing this high-tower geometry axiom system, he still faintly feels that the basic view of mathematics has quietly changed.

In the enthusiastic atmosphere of discussion, Samantha suddenly stood up, printed a copy of the book in her hand, and then ignited it with a flame.

"With some company, the world after you die will be full of colors," she whispered.

The other Arcanists also calmed down, and were quite sighed. Fortunately, it was released at this time.

After dealing with the aftermath of Haven, Rachel, Samantha, and others left his room one after another. During the process, an Arcanist hurry up and read: "'Difficult problems in current mathematical research'?" "

"... Can any even number greater than 2 be written as the sum of two prime numbers ..." After reading the question, he fell into dull thinking.

"Four-color problem?" The other Arcanist turned to the next page.

After hearing their words, Samantha and Rachel looked at each other, and quickly turned to the content behind.

For a moment, there was a statue-like arcanist standing in the corridor, and they kept thinking about something in their mouths, their expressions were wild but mad.

After not knowing how long, the footsteps awakened Samantha and Rachel, and then saw a circle of "vertigo" in each other's eyes.

As a result, Rachel laughed: "These issues are horrible. At first glance, it seems very simple, but if you think about it, you will find it extremely difficult ..."

"So even Lord Evans is stumped." Samantha smiled rare.

"Last question, the hairdresser's paradox?" Rachel saw the last few pages, "... a hairdresser in a small town promised after something," I only help everyone in the town who doesn't cut their own hair. Haircut ', should he cut his own hair? What's the problem? "

"This ..." After Samantha pondered a little more, the books in her hand fell to the ground with a bang.

Alas, the rest of the Arcanist who heard Rachel's words also let the books land in amazement.

This is a well-known paradox of set theory. At the current level of research, this means shaking the set theory, and set theory is the foundation of the mathematical field. Therefore, it can be said that this paradox makes people doubt The effectiveness of the basic structure of the entire mathematical field!

"Just excited about the perfection of set theory, and now I have to face the horrors and despair that come with it ..." An Arcanist said something similar to what Havin said just now.

…………

Ellestine and Nord Daniel wandered around Arlinge ~ lightnovelpub.net ~ seeing the shade, many arcanists were studying leisurely and hard.

"It's hard work. It's no wonder that the Magic Council can develop so quickly." Elestine sighed, and then curiously looked at one of the young magicians. "What book is he reading?"

"Mathematics ... the basics ..." Nordaniel recognized word by word with strong eyesight.

"Mathematics ..." Elestine nodded, and just about to turn away, but heard Nordanil add in doubt: "These words have a red cross drawn on them, and there are other handwritten words below ... ... "

Ellestine became more curious: "What word?"

Nordenier carefully discerned again: "The devil ... the book ..."

"?" Ellestine repeated inexplicably.
