technical type

Officials have different grades and different costumes, and according to factors such as the favorite clothes of the gods represented by the stars, arrange reasonable positions as much as possible to avoid collisions.

Some of these related things can no longer be said to be pure data, at least not in terms of numbers, but they need to be taken into account when calculating, so the calculation cannot be summarized into something like a formula, and it must be comprehensive. consider.

This also involves the imperial court's definition of itself. The theory of five virtues is still very marketable. For example, the current imperial court pays attention to the virtue of water and favors black. In some clothing characteristics, black is respected. Of course, it is due to the nobility. Considering the identity, it cannot be pure black, and the tattoos and embroidery on it must be extraordinarily golden.

What kind of astrology corresponds to water virtue, what kind of main star should be the main star, what kind of temperament is the god master of the main star, and how to do things that suit the other party's preferences... All these trivial and complicated things must be included in the calculation within.

In general, calculation is not only calculation, but also includes the part of "guessing".

The calculations that Ji Mo learned from Ji Changwei before are mainly in simple numerical calculations, and there are not many variables of this type involved. During the time I have been with Ji Huan, I have seen his considerations in these aspects, My heart is so cold and cold, it's too complicated.

The other point is that he really doubts that these things are useful?How useful is it?

For a big ceremony, it should be more solemn and serious, just stand in line, and be more rigorous. Besides, it is a bit too picky to arrange everyone's position in this way.

The key is that this kind of benefit is more like a superstitious "death", whether it is there or not, it is all said by the astrologer, what is the real result, who can verify it?

There have been real examples in history. It was also not long after a certain grand ceremony that thunder and fire hit the main hall and damaged a corner of the hall. It was not completely burned, but it also blackened many beams and columns. As a result, the astrologer did not think that his grand ceremony There was a problem with the arrangement, and instead of winning the favor of God, it was believed that the emperor was dishonest when he worshiped, which caused God to be angry and Lei Shen to punish him in a small way.

This kind of "not sincere" persuasion is the most idealistic, but also the most unconvincing.

A natural disaster in a certain place, drought for more than three months, after repeated calculations by the astrologer, the final result is "God's punishment, no forgiveness", and then the emperor, apart from other disaster relief matters, issued an edict of guilt, expressing that he was guilty of God , only him, begging God to forgive the people, and rain down on everyone.

From this point of view, although the Sitianjian to which the astrologer was affiliated was an imperial institution, it did not speak for the emperor. Similarly, it did not represent absolute justice.

The astrologer in the previous story was not arrested at the time, but he was convicted of a small mistake afterwards, and he was directly exiled to other places and died.

In the latter story, the one who forced the emperor to issue his own edict did not end well, as if all the benefits in the past were not counted, he was also questioned afterwards, which was similar to the previous one.

The enlightenment from these two stories to Ji Mo is that God’s spokesperson is not so easy to be. Instead of engaging in that kind of mysterious idealism, it is better to directly use a more rigorous formula to represent everything. What is the number? No matter what the result is.

Of course, such things are considered rare. Astrologers who are not famous for provoking the emperor, most of the time they do things to predict disasters.

For example, what is the angle between a certain star and a certain star? Such a change in the value may mean a dry season in a certain place. Early warning and preparation can avoid a natural disaster. ordeal.

This kind of result that can basically be obtained through basic calculations is quite reliable, and in Ji Mo's view, it is also very powerful.

For example, how many days in advance it is calculated that there may be a meteor shower, even if the understanding of the meteor shower is different, it is a very powerful thing to be able to predict this astronomical phenomenon.

In ancient times, the phenomena that they could not understand were usually called "gods". Meteor showers, in the eyes of the ancients, means that there may be major changes between the heaven and the earth. This kind of change is usually a sign of troubled times, so-called "stars descending to earth" and "evil stars descending to earth".

When it cannot be accurately predicted, it can be regarded as a catastrophe is coming, but when it can be predicted, there are less unknowns and more understanding, although there are similar meanings left, for example, it represents a certain place There will be chaos—since so many people will be born, there will naturally be more people who will die, but in general it is already an understandable phenomenon. If people are born, old, sick and die, there must be a cycle in this world.

However, due to the rarity of such cases, it must also be taken seriously.

On the observatory, Ji Mo stood beside Ji Huan, and there were many people standing beside them.

The imperial court does not allow people to study astronomy and astrology in private, so only the imperial court has such a tall observatory, which is higher than the small observatory in the Ji family.

A similar height is a stargazing building in the imperial palace, which is specially used for the emperor's stargazing.

It was late at night, and Ji Huan led Si Tianjian and the others to stand on the observatory, looking up at the sky without speaking to each other. What they were waiting for was a meteor shower.

It is not the first time for Si Tianjian to predict the arrival of the meteor shower. From the inaccurate prediction at the beginning to the present nine out of ten, it has also gone a long way. Up to now, the accuracy can reach The position of "engraved" is on.

This is not easy.

Ji Mo lamented the huge amount of calculation involved, and thought of his difficult future in the future. For this kind of thing, he really should find a science student to do it as a professional counterpart.

But these are not interesting, just pass the boring waiting time and think about it.

A group of people stood on the stage almost without making a sound, like wooden figures. In the dead of night, there was indeed a somewhat more terrifying atmosphere.

If someone who didn't know saw it, he would think it was doing something.

Ji Mo was still thinking about what was there and what was not, and he didn't know who said: "The east is bright, let's get up!"

Following this sentence, Ji Mo looked towards the east subconsciously, and saw a shooting star slanting down in a long line. Before he could marvel at the beauty of this shooting star, there were countless stars following him, flying down at a similar angle , Their speed must be very fast, and they can all spark sparks, but in the eyes, against the black sky, they are extraordinarily beautiful.

Like the blooming fireworks, the flowing fire is so beautiful and compelling.

"count--"

Someone reminded loudly that if the sound of a bell runs out, the long ending sound is like the tail of a shooting star, dragging and dragging, leaving their own traces on the sky.

The surrounding was silent again, and everyone was watching intently. At the same time, they were memorizing the number of shooting stars. Ji Mo also raised his spirits to follow along. These things need to be recorded, and they are also the data for the next calculation, which is very important.

The meteor shower came fast and frequently, and the human eyes seemed to be unable to keep up with it. All the starlight was quickly covered by the slashes. The local residents, like refugees, passed by in a hurry.

But a few minutes are as fleeting as fireworks and dissipated. Ji Mo wiped the sweat on his forehead and began to summarize the things he remembered into data. A certain place is a radiant point, how far is it from the main star, and which star area is it...

He is still converting the data in his mind, and some people are already cheering: "I got it right, I got it right!"

"It's clear that my prediction was right!"

Si Tianjian has long recorded that the two meteor showers per year are considered to be large in scope and wide in visibility. Basically, you can see them when you look up. In addition, there are some scattered meteors. Due to the intermittent time, each time they cross the sky The number of rain is not many, so it is not included in the category of "rain", but will be recorded separately, and it will be a special case that reflects someone or something.

In fact, the ones that come three to five at a time and come only once in a long time can also be regarded as meteor showers. At least in Ji Mo's opinion, the observation records of this kind of meteor showers are comparable to those of "bringing stars down to earth" and the like. more believable.

"Okay, why are you arguing, go back if you have nothing to do, and talk about the calculation results tomorrow."

Ji Huan's words suppressed the excitement of many people and made some people retreat from the observatory.

This meteor shower is the largest on record. The sight of thousands of meteors passing across the sky is truly unforgettable once seen. This requires more people to watch the record together. Otherwise, three or five meteors per hour, Anyone who comes here can write it down, and there is no need for everyone to keep watch.

Record the number and location, and compare the data tomorrow to see if there is any difference, and then calculate one or two, so many stars, it is impossible to have no origin.

In fact, the ancients still had a lot of ideas about why there are so many stars in the sky. According to the theory that a certain star conceived with a certain star to give birth to a certain star, the stars in the sky were also arranged out of family relationships beyond the pedigree relationship. , in which love and hatred, it is absolutely no problem to arrange a myth and legend.

Ji Mo has always doubted whether those myths and legends about the gods in the sky were all made up by astrologers. They are too reasonable and well-founded, and the rigorous logic of the argumentation is indeed the style of a science master.

After watching a meteor shower, what you get is not romance, but homework—the aftertaste!For Ji Mo, it was calculation.

"What you see today, calculate one or two, and leave it to me tomorrow."

Ji Huan is getting older, and he rarely stays up all night. After leaving the observatory, he left homework for Ji Mo and asked him to finish it by himself, so he went back to sleep first.

Ji Mo looked at the sky, judged the time, and really wanted to tell him that strictly speaking, it is already "tomorrow".
