The tip of the snow-white quill slides quickly across the paper, and the unique reddish color of the gallic ink penetrates deep into the white paper fibers, as if there is no end to it.

To sum up, the contribution of the ancient Arabs to science was not in excavation, but in tolerance. To its credit, although, as in the West, there were periods of fanatical religious conquest. But after that, the Arabs showed admirable tolerance. Whether it was the Greeks, the Persians, or the Jews, they were able to move freely in the Arab countries without persecution. It is for this reason that scholars of different nationalities and religions have been able to find a safe haven in Arab countries. At the same time, a large number of scholarly works that had been lost in the West for various reasons were preserved to the greatest extent in the land of the Arabs. It is particularly remarkable that the Arabs have preserved almost all of the ancient Greek scholarship, the vast majority of ancient Babylonian scholarship, and even most of the ancient Indian scholarship. They cherish and admire the wisdom of these predecessors so much that it far exceeds their own wisdom - almost all of the original works of ancient Greek people such as Archimedes, Euclid, and Apollonius that we see today come from Arabs, while the writings of Arab scholars themselves are often restored by citation.

There is no doubt that the Arabs of that time were ahead of the West in the academic field, and this can be seen only in the words that are still in use today: 'algebra' and 'algorithm' in mathematics, 'alchemy' and 'alembic' related to ancient chemistry, 'zenith' and 'nadir' in astronomy, 'camphor' in ancient medicine, 'camphor' in ancient medicine. Panacea' (elixir), blah blah blah. These terms, which we are familiar with today, all come from the Arabic language.

What's more, the attitude of the Arabs towards science is particularly different from that of their predecessors. They did not study science in order to understand the mathematical design of the natural world, as the ancient Greeks did, nor did they study science in order to 'comprehend the word of God,' as the Christians did. They believe that the purpose of studying science is to govern things in nature – an idea that is unprecedented. This unprecedented view gave science the power to get rid of the mysterious, the mysterious, and the unknowable for the first time. Since the Arabs, science has ceased to be a treasure that only a few people can understand, and it is no longer mysterious; Since the Arabs, science has become a concept that everyone can understand and grasp in principle. Later, this became an important part of the method of identifying the authenticity of science......

…… With the Crusades, the ancient Greek, Hebrew, ancient Babylonian and ancient Indian collections in the fields of mathematics, science, and culture preserved by the Arabs, as well as the scholarly works of the Arabs themselves, became the opportunity for the later Renaissance and even the Industrial Revolution......"

At this point, Dome put aside her pen for a while and stretched her body that had been sitting for too long, her arms aching a little from writing for a long time. Of course, she can also change hands, but her handwriting is too different from her left. It is better to avoid two different handwriting on the same project report as much as possible.

Looking up, there was another girl sitting at the table in front of him, looking at him with a smile that seemed to be "I already knew".

If it was her, she might have seen herself like this not long ago.

Speaking of which, coming to the library today to write a summer project was also based on her suggestion. Is it because you "saw" something that is going to happen? But no matter how he thought about it, Dome couldn't imagine what would happen to the library.

If you ask directly, you probably won't be able to get an answer. Although Hoshikawa is not the kind of girl with bad tastes, if she thinks that it is better not to say it than to say it, no one will be able to ask for any answer from her. For some reason, she's quite stubborn in this regard.

But to be honest, Domino also somewhat understands why. Because in essence, what Hoshikawa possesses is not the kind of legendary prediction ability in the true sense. Rather, the miraculous foreknowledge that seems to be able to predict the future is just a manifestation, and has nothing to do with the real "seeing through the future".

Broadly speaking, the existing interpretation of Hoshikawa's abilities is that there are two different manifestations. One is the acquisition of projections from other dimensions, which is a distorted backwards of possible probabilities, which itself is distorted and uncertain, but this should be able to be changed, at least in principle, by choosing another possibility; The other speculation is that some definite result is obtained by chance in some uncertain way, the difference is only the way in which this result occurs, and whether this can be changed is completely unknown.

The latter should be powerless at the moment. However, if too many events are introduced in the former, the probability of decoherence will increase, and the events will become more and more uncertain. So if it's not something too bad, it's probably better not to add too much uncertainty.

"What is written in a book is just words."

The friend in front of her said something like this. It doesn't sound like a good idea, but Qiongno also knows that his friend has some difficulty in expressing himself.

"Kaihara-san."

While she was still figuring out what Hoshikawa wanted to say, someone called her name.

"Shhhh Sister, keep quiet in the library. ”

"Ahh Mai Korto said, looking at Qiongno's left hand as if she had seen something new. "By the way, Kaihara-san, it turns out that you are really left-handed."

"Weird, isn't it?" For Maikoto, who has never been restrained at all, Dome smiled helplessly, "It doesn't affect me with my right hand, but my handwriting is not very good." ”

"No, no, no, of course it's not strange. But the use of a quill is really ancient. ”

Electronic products have long been the norm in the school park.,But in order to keep students from losing their writing ability,In most cases, it is still required to complete most of the homework through paper writing.。 However, the vast majority of students should choose pencils that are easy to modify, and a few may choose pencils. There is probably no one who uses such an ancient quill like Dome Nao.

"This? It was a gift from my mother. ”

As she spoke, she closed the ink outlet of the refill in the hollow barrel and wiped it with a tissue before fastening it to her hair as a hairpin.

"Sister, what the hell are we doing?"

"Huh? Ah, that's right. As if she had finally remembered, Mikoto nodded, "Kaihara-san, Hoshikawa-san, do you want to go with us to meet Hatsuharu-san's new friends?" ”

(Could it be that this is what you don't see?) ）

She looked at her friend beside her, and Xingchuan closed the book she was looking at without directly "snapping".

"I'm not going, I'm sorry."

Hoshikawa stood up and gave a brief salute, then turned to leave.

She hadn't taken a few steps, and all of a sudden, she was looking back again.

"Congratulations."

She said this, but she didn't explain anything.

Even if she knew that she had a language barrier, this time it would seem a little too abrupt and inexplicable.

What did she see?

Dome tilted his head, his face uncertain.

_

"I see, the topic chosen by Kaihara is history."

In the afternoon, under the clear blue sky, the girls gathered. In the school city,It's a commonplace scenery that can be seen every day.。

It's just that the content of the conversation between the parties is somewhat unusual if compared to their age. At least no matter how you listen to it, it doesn't look like a topic that a 14-year-old middle school girl talks about.

"It wasn't something I chose, but my father's suggestion that I try to challenge myself in a field that I hadn't been exposed to. I thought it would be difficult, but when I actually did it, I quickly became proficient. ”

"Wow...... If someone else says this, it shouldn't be credible, but if you say it, Kaihara-san, I always feel a little subtle credibility......"

Shirai Kuroko muttered quietly.

"Well, it's not about how deep the subject is. What about Misaka-san? ”

"It's economics."

"That's a strange thing......"

Mai Trillion held her chin and her mind began to diverge casually.

"What's weird? Misaka-san. ”

"According to your point of view, the Arabs had such a glorious ancient scientific civilization, why did they later become obscure in the history of the development of modern science?"

Dome looked at Mikoto and didn't speak for a long time.

"Did I ask any strange questions?"

Mai Koto scratches her cheeks.

"No, it's better to ask the key point. In fact, it's even a paradox. If you look through history, you will often be surprised to find that the closer a country seems to be to modern civilization, the farther away it is from modern civilization in the process of development. This is true of Arab civilization, and it is also true of Asian civilization. There are many theories, but the jury is inconclusive. Even Albert Einstein once commented on this, and his view was that the birth of modern science must be based on three elements: first, Aristotle's "problem-solving" process, second, Euclid's axiomatic deductive mathematical logic system, and third, the process of physical experiments initiated by Galileo. He then concludes that it is not surprising that ancient civilizations such as China (note: Chinese mathematics followed the path of a system of mechanical algorithms, and the axiomatic deductive system was introduced much later) did not develop modern science, and that in fact it was pure accident that the Western world was able to put together these three elements. In other words, this is not an accident in itself, but it may be a real accident that the opportunity for modern science to emerge in Western civilization is the real accident. However, this is just one way of saying it. ”

On this topic, even Dome himself can't say why. She was only introduced to these things as a summer project, and after all, she could not have become a true historian.

"Okay, okay, since you've left school, don't talk about homework, it's a headache." Shirai interjected. "Okay, we're going to meet Hatsuharu's new roommate today."

Zuo Tian walked at the front of the line and quietly glanced back.

The sense of distance can only be felt somewhat. These Tokiwadai top students, even the usual conversations related to schoolwork are extraordinary.

Of course, I don't care about that anymore. Everyone is different, and no one can be someone else. It's just a little bit, and something else happens.

Ah, yes, I know.

Even if it's just unbelievably ordinary, even if you can't even understand your friends' conversations, even if you find yourself bored...... But I was still attracted.

I don't know when I was deeply attracted by this commonplace street scene and the best boring time I spent with my best friends.

Stretching his arms, Saten even hummed softly.

"Saten-san, you seem to be happy?"

"Of course, isn't Chu Chun's roommate my best friend candidate?"

Without the slightest suspicion, such a thing was said.

"It's really ......" sighed, and Shirai suddenly noticed that Dono, who had been walking unhurriedly beside her, stopped. Kaihara-san? ”

_

Breathe...... It began to rush and feel an unbearable pain in my chest.

So that's it...... It turned out that this was the "result" that my friend saw......

In the chest cavity on the right side, the heart seems to be skipping several beats in a row, and there is an illusion that the whole body is screaming.

Headaches that make it feel like hot magma has replaced blood; Unable to balance the body, the whole world began to spin.

It's not a reaction to physical discomfort or intense exercise. It's the memory of the past, which is screaming in the mind.

Swallowing the urge to let out a mournful scream, the dark clouds in my heart were dissipating, and a ray of light was shining in.

She saw the slightly shocked expressions of her friends around her, but at this time, what she could see was not now.

In an instant, take a step. Crossing the gap of time, you can run through the passage to the past that has been built by your current friends.

The world is changing, time is changing, and people are inevitably changing. There is only one thing that does not change.

Open your hands and embrace them firmly in your arms. At this moment, my mind was full of impulses that I didn't want to let go of again.

"Finally...... I've finally found you, Jinyi. ”

She said.

This voice, which I had been looking forward to countless times in my heart, has now traveled through time and space, through the memories that connect time and space.

At this moment, it finally became a reality.

- For the sake of friends from the past.

=================================================================

Christmas Eve complaint: The previous chapters talked about a lot of Christianity-related things, and I was a little worried about being suspected of having stereotypes against Christians, so I specially explained it, but now it seems that I am thinking too much. If you think about it, a group of merchants recently sold apples at high prices on Christmas Eve, and even those who have talked about Christianity tampering with the scriptures many times have come up with the idea that "these people are not going to be incompatible with Christianity". Well, it seems that even if you want to worry, it won't be my turn, if you really have something, at least there will be the top of the group of people selling "peace fruits" in front, right?

Just kidding, be serious.

In the past few days, I have come into contact with two religious friends, and they have talked to me about the original Bible in a more harmonious and serious manner. Although they have some opinions, they do agree with "me" in the end (not me, but they think so). I don't dare to take credit for this, which is the conclusion of countless historians) about the premise that "all the versions of the Bible that we have now are not the earliest originals." Thank you very much to those two who were able to put aside prejudice and talk about this topic from a purely historical perspective.
