Magic Tower Starry Sky

Chapter 28: Lost Astronomy



After sending off the guests of the Chamber of Commerce, the Tower of the Great Sage returned to its usual calm. After throwing a bunch of trivial matters to the two young apprentices, Lin had extra time to think about astronomy.

Astrology can be regarded as a long-established knowledge in the lost world. But this knowledge is here, the most important thing is to solve the problem of the two satellites in the sky.

In the case of the earth with only one moon, the earth's tides and weather will be affected by the only satellite.

The Lost World has two satellites, causing more complex changes in the weather system. The weather is also related to agriculture and food, so naturally a special profession is derived to predict the weather. This profession is an astrologer, one of the branches of the magician.

The knowledge that a magician needs to learn also includes astronomy that combines mysticism. Predicting the weather can only be regarded as entertainment in leisure time. But for conscientious rulers, the weather is related to the harvest of food in the territory, so naturally they cannot take it lightly.

Gradually, some magic apprentices with poor talent and insufficient resources gave up the accumulation of mana and power, which was equivalent to giving up the improvement in magic, and they turned to serve the lords everywhere. Because astrology and weather forecasting focus on knowledge. The name of astrologer was also separated from magicians, and was despised by the masters...

There is no way, which astrologer is not unable to advance on the road of magic, so he retreats and turns to beg for food from the nobles. Therefore, the two professions have contempt and jealousy as their main emotions, and they are not friendly to each other.

However, Lin's point is that astrologers still have some accumulated achievements in astronomy. It was like what he was looking at now, the star map bought with a lot of money. The astrologers in the Lost World haven't started their brains like the scholars in ancient Greece on the earth, picked out some stars from the entire starry sky, set them as constellations, and accompanied them with a sentimental story .

In the entire star map, only 417 stars are marked. It is mainly the orbits and changes of the two satellites, which traverse the entire layout of the star map. This number is far inferior to the fixed number of stars in ancient Earth, regardless of Eastern and Western astronomy, which is more than a thousand.

Looking at this star map, Lin felt a little helpless. The circle of astrologers is more closed than that of magicians. Perhaps due to the influence of inferiority complex, astrologers have a more self-respecting attitude towards the knowledge they have researched, and are rarely willing to share it with others.

The map that Lin bought was an amateur version edited by magicians, and it had a few more stars than the standard version of the star map provided by the association. Still, Lin was disappointed.

And the nights of the previous few days, the main job was to fill in the blanks of his own star map, the flat version. The most difficult point is that one must first order a North Star as a benchmark, so that it is convenient to draw a sufficiently accurate star map.

Because of the lost world, most people who study astronomy focus on the two satellites. Coupled with the real existence of gods, there is a saying that exploring the starry sky is spying on the kingdom of God, which will also offend the gods. Therefore, research in this area is kept secret by most people, so a lot of work has to be done by oneself.

Thinking about my workload, I had to go all the way from the era of the Greek philosophers to the era when the general theory of relativity was established. This part of the technology tree that has yet to be illuminated makes my scalp tingle just thinking about it.

In Tripwood's version of the star map, the number of stars is nearly 2,000. Now, Lin began to think about another thing, which method to use to measure the distance.

The most primitive parallax method has to be measured in two places, so it is basically given up first. As for the radar method using the principle of sonar, looking at the pure and non-industrial-polluted sky outside, I directly gave up the idea of ​​going to the radar technology tree.

More feasible methods are the many methods derived from the annual parallax method and the red shift phenomenon. However, the accuracy of these methods is very dependent on the accuracy of observation. Just trying to find a way to measure the angle of one second (1/3600 of a degree angle), with the existing equipment and the knowledge of magic that can be used, I don't know how many brain cells will be killed.

Also, in order to use the annual parallax method, the Lost World version of one astronomical unit has to be remeasured. That is the average distance between Midi and the sun. Along with that, the star radius of Midi, as well as its revolution, rotation period, and even the unit of time have to be re-measured or defined accurately.

Thinking of this, Lin had to think about the star map on the wall of the restaurant again. It is one of the few things in the Tower of the Great Sage that has been handed down since the beginning of its construction, and it clearly shows the star system where Midistar is located. This also proves that people in the lost world have abandoned the geocentric theory and entered the more realistic heliocentric theory.

In that stellar system star map, although the distances between the planets are not correct, but generally use equidistant concentric circles as orbits, but the revolution periods of the six planets are very accurate.

Among other things, just because the star map has been running for thousands of years, the positions of the six planets on the star map are almost the same as the actual results of Lin's observations, which shows how amazing the astronomical achievements of thousands of years ago are. Then there is the lack of progress for a thousand years... similar to the problems of a country that claims to have an ancient civilization of 5,000 years.

Lin also wanted to study the operating principle of that star map. However, the results of the actual investigation only confirmed the complexity of the magic principle behind the star map, which could not be clearly understood for a moment.

In addition, most of the end points of the energy channel are concentrated at the position of this star map, which also makes Lin dare not change or stop the energy supply here rashly. Except when the magic tower was rebuilt, when the situation was not clear, there was a power outage in the whole tower, and it was accidentally discovered that the star map could continue to operate, obtaining energy supply from unknown sources.

All kinds of wonders made Lin decide to keep this star map and maintain its original appearance for future research and comparison. Of course, the subsequent transformation of the magic tower also bypassed the energy supply of the star map to maintain the continuity of its operation.

Incidentally, the phenomenon of the Six Stars Lianzhu will happen within a year or two. That is, six planets are connected in a line. This kind of situation, in the ancient times of the earth, always became some kind of astronomical warning; even in modern times, it has also become the subject of novelists' special books.

However, when he was on Earth, Lin only encountered Qixing Lianzhu once in 2000 AD. I don't know if the change in Taiwan's political arena counts as an influence. Other than that, nothing bad happened. The main reason is that the orbits of the planets are not on the same plane, but have a slight angle deviation. It is impossible to completely connect them in a straight line in three-dimensional space.

Then comes the calculation part. It took a lot of effort to build the alien version of the computer, just to simplify the calculation process. Think about how NASA had a whole team of computing personnel before introducing IBM computers. And the mathematicians in the Lost World can be described in two simple words: none. In a world where multiplication doesn't even exist, what can one expect?

It is actually not complicated to use a computer to do calculations, but the difficulty lies in the accuracy of floating point numbers. The most primitive computer, the error in the decimal point can lose to hand calculation. This is limited by data structure, and numerical normalization factors.

The program improvement in this area is handled in the form of an array. Before time travel, various programming languages ​​had already developed quite mature developments and paradigms, but those were all based on binary...

In the lost world, the octal computer based on the eight magical powers must have corresponding conversions for the relevant theories. This makes someone die a bunch of brain cells again.

In short, since he settled down in the Tower of the Great Sage and began to formally explore the starry sky, looking for the way home, someone has been constantly breaking down and reincarnating. And this is one of the reasons why so many materials are purchased from the chamber of commerce.

In addition to some ideas in my mind, I want to try it out. That is, when a person collapses, he goes into the forging room and beats it, as if it can help the soul return. Moreover, the finished product can more or less make up for the frustration in astronomical exploration.

And on a broken afternoon, simply beating and beating was no longer enough to restore the mushy head to its original state. In the weird eyes of the two girls seeing the walking dead, Lin seemed to be floating into the warehouse on the first floor.

The godless eyes looked for materials that could touch the nerves, and the stones piled up in the corner belonged to the high-grade stone materials used to build the walls of the magic tower. Originally, Lin had the idea of ​​repairing the Tower of the Great Sage, but he had to maintain consistency in order to maintain the overall energy balance.

Unfortunately, the Tower of the Great Sage has been built for thousands of years. Although the technology is backward, the materials are top-notch. This kind of stone called striped turquoise stone is not only rare, but all known veins have been mined. In other words, there is nowhere to buy money.

These stones are the only inventory of the Xijia district branch, and they are provided to some wealthy magicians to make important parts of stone golems. And this weight, even a wall can't stand up.

When the manager of the Chamber of Commerce came to visit a while ago, Lin did raise this issue. As a result, the other party gave a bad idea—how about demolishing other people's towers?

After the two were speechless, the matter was never mentioned again.

Now looking at this pile of stones that are too tall and too low, a thought arises spontaneously.

Without calling anyone else, Lin was shirtless and carried the stones up to the open platform on the second floor by himself, only using the Great Strength Technique. UU Reading www.uukanshu.com This kind of stone, which is the basic material of the magic tower, has a major feature of high density. Under the same volume, it is heavier than iron. So even though Lin used the giant force technique to assist him and moved all the stones up to the second floor, he was still sweating.

Since this kind of stone is rare and precious, no unnecessary cuts were made for the convenience of transportation. Instead, it maintains the original shape, a round and irregular appearance, with traces of water washing. This reminded Lin of another thing that was missing in the Lost World on Earth—the open-air hot spring pool.

No hot spring water?

It doesn't matter, connect the alien plane by magic. The magma can be whole, not to mention the hot water with a bit of sulfur. This project was done once before when planning the tap water and sewage system of the entire tower. Do it again this time, or start from the water elemental plane. Although looking from the abyss, it may be easier to find hot spring water that meets the standard.

But considering the characteristics of that place, it is unknown whether soaking in it every day will have any adverse effects. In addition, if such a hole is opened, it is also unknown whether local residents will come along the hole. Don't gamble on luck when you are uncertain about things. This is the experience of watching countless earth movies.

What does Murphy's Law say. ‘Anything that can go wrong, will go wrong’.

Lin Ke didn't want to be **** by the little devil halfway through the hot spring.

As for overall planning. Even if Lin himself has not soaked in a few hot springs, he has seen many photos of open-air hot springs, and even puzzles made in open-air hot springs. So after paving the stone slabs and laying stones to make a difference in height, and connecting to the elemental plane suspected of hot spring water, some plants were placed outside the tower and arranged. After a busy afternoon, although it is not as good as the famous soups in my impression, it still looks good.
