After seeing 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 little apprentices, Lin had extra time to think about astronomical matters.

Astrology is also a long-established science in the world of labyrinth. However, the most important thing in this science here is to solve the problem of the two satellites in the sky.

In the case of the earth, there is only one moon, and the tides and weather of the earth will be affected by the only moon.

The world has two moons, which causes more complex changes in the weather system. The weather is related to agriculture and food, so it is natural to derive a special profession to predict the weather, which is one of the branches of astrologer and magician.

Magicians also have to learn astronomy, which is a combination of the occult, and predicting the weather can only be regarded as leisure entertainment. But for conscientious rulers, the weather is crucial to the amount of grain harvested in the territory, and naturally it cannot be taken lightly.

Gradually, some magic apprentices with poor talent and insufficient resources gave up the accumulation of mana power, which is equivalent to giving up the improvement of magic, and they turned to serve the lords everywhere. Because astrology and weather prediction are all about knowledge. The name astrologer became independent from the magicians, and was then despised by the magicians......

There is no way, there is no astrologer who is not unable to move forward on the path of magic, so he retreats to begging for food from the nobles. Therefore, the two professions are dominated by contempt and jealousy, and they are not friendly to each other.

However, Lin's point is that astrologers still have some cumulative results in astronomy. It was as if he was looking at the star map that he had spent a lot of money on. The astrologers of the lost world have not yet started with a big brain like the group of scholars in the ancient Greece of the earth, picking out some stars in a whole starry sky and setting them as constellations, accompanied by a lingering and sad story.

The entire star map is marked with only 417 stars. It is mainly the orbits and changes of the two satellites, which traverse the layout of the entire star map. This number is far inferior to the ancient number of stars in Eastern and Western astronomy that were more than 1,000 stars.

Looking at this star chart, Lin was a little helpless, the circle of who called astrologers was more closed than magicians. Perhaps due to the influence of low self-esteem, astrologers are more self-cherishing of the knowledge they have researched, and are rarely willing to share it with others.

And the picture that Lin bought was still an amateur arrangement version of the magician, which was a few more stars than the standard version of the star map provided by the association. But it still disappointed Lin.

And the night a few days ago, the main job was to fill in the blanks of your own star map, the flat version. The most difficult part is that you have to map the North Star as a benchmark to be accurate enough.

Due to the world of Lost Earth, most people who study astronomy have their eyes focused on two moons. Coupled with the fact that the gods are real, there is a saying that the exploration of the starry sky is spying on the kingdom of the gods, and it will also offend the gods. Therefore, most people are secretive about this research, so a lot of work has to be done by themselves.

Thinking of the amount of work that has to be done all the way from the time of the Greek philosophers to the era when the general theory of relativity was established, the part of this tech tree that needs to be lit up makes my scalp tingle just thinking about it.

Now that there are nearly 2,000 stars on Tripwood's star map, Lin began to think about another matter, how to measure the distance.

The most primitive parallax method had to be measured in two places, so it was basically abandoned first. As for the radar method that uses the principle of sonar, looking at the pure and pollution-free sky outside, I directly gave up the idea of going to the radar technology tree again.

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

Also, in order to use the annual parallax method, it is necessary to re-measure the astronomical units of the Lost World version. That is, the average distance from the Earth Star to the Sun. In addition, the radius of the star of the Lost Earth, as well as the revolution and rotation period, and even the time unit must be accurately measured or defined again.

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 Great Sage's Tower that has survived since its inception, and it clearly shows the star system in which the star is located. This also confirms that the people of the world have abandoned geocentrism and entered heliocentrism, which is closer to reality.

On that map of the star system, although the distances between the planets are not correct, but the orbits are generally used as concentric circles at equal distances, the orbital periods of the six planets are very accurate.

Not to mention anything else, just the star map has been running for thousands of years, and now the star map positions of the six planets are almost the same as the actual results of Lin's observations, so you can know how amazing the astronomical achievements were thousands of years ago. And then there is a thousand years of non-growth...... It's similar to the problem of a country that claims to be a 5,000-year-old civilization.

Lin also wanted to study how the star map worked. However, the results of the actual investigation only determined that the magic principle behind the star map was complex, and it was not clear for a while.

In addition, most of the energy channel endpoints were concentrated at the location of this star map, which also made Lin dare not rashly change or intercept the energy supply here. In addition to the original reconstruction of the magic tower, when the situation was not clear, there was a power outage in the whole tower, and it was unexpectedly found that this star map could continue to operate, and the energy supply from an unknown place was obtained.

All these wonders led Lin to decide to keep the 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 will occur within the next year or two. That is, six planets are connected in a line. This situation, in ancient times on earth, would have been some kind of astronomical warning; So much so that in modern times, it has also become the subject of special books by novelists.

However, when he was on Earth, Lin only encountered a seven-star alignment once in 2000 AD. I don't know if the change in Taiwan's political arena can be regarded as an impact. 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 angular deviation, and it is impossible to completely connect them in a straight line in three-dimensional space.

And then there's the calculation part. The reason for the creation of the Otherworldly Computer is to simplify the process of calculation. Think about the fact that before NASA introduced IBM's computers, it had raised a whole team of computing personnel. And the mathematicians of the world can be described in two simple words: no. A world that doesn't even exist for multiplication, what can you count on.

It is not complicated to use a computer to do the calculation, but the difficulty lies in the accuracy of floating-point numbers. In the most primitive computers, the error in decimal points is lost to manual calculations. This is limited by the structure of the data and the normalization of the values.

This aspect of the program is improved by using an array approach. Prior to the crossing, various programming languages had mature developments and paradigms, but those were based on binary......

In the world of Mazeland, the octal system computer based on the eight magical powers must have corresponding transformations for the relevant theories. This in turn makes someone die with a bunch of brain cells.

In short, ever since settling down in the Tower of the Great Sage and starting to officially explore the starry sky and find a way home, someone has been constantly reincarnating in a collapse and cheering up. And this is one of the reasons why so many materials are purchased from the Chamber of Commerce.

Except that I have some ideas in my head and want to try it. When people are collapsing, they go into the forging room and knock and knock, as if they can help restore the soul. And the production of the finished product can more or less make up for the frustration of astronomical inquiry.

And on a crashing afternoon, a simple beating was no longer enough to restore the mushy head to its original state. Lin was in the strange eyes of the two girls when they saw the walking dead, and the whole person seemed to float into the warehouse on the first floor.

The godless eyes searched for materials that could touch the nerves, and the stones piled up in the corners were high-grade stones that belonged to the walls of the magic tower. Originally, Lin had the idea of repairing the Great Sage's Tower completely, but he had to maintain consistency in order to maintain the overall energy balance.

Unfortunately, the Great Sage Tower was built for thousands of years, and although the technology is backward, the materials are top-notch. Not only is this stone scarce, but all known veins have been mined. That is, there is nowhere to buy if you have money.

The stones brought in were the only stocks in the Siga branch and were used by some wealthy magicians to make important parts of the stone golems. And this amount of weight can't even stand a wall.

A while ago, the manager of the Chamber of Commerce came to visit, and Lin mentioned this issue. As a result, the other party gave a bad idea - how about demolishing someone else's tower?

……

After the two were speechless, the matter was not mentioned again.

Now looking at this pile of high and low stones, a thought arises spontaneously.

Without greeting others, Lin was shirtless, only using the Great Strength Technique, and carried these stones up to the open platform on the second floor alone. One of the major characteristics of this kind of stone, which is the basic material of the magic tower, is that it is dense, and under the same volume, it is heavier than iron. So even though Lin took the assistance of the Great Force Technique for himself and moved all the stones to the second floor, he was still sweating.

Because this kind of stone is scarce and precious, it is not necessary to cut it in order to covet the convenience of transportation. Instead, it maintains its original shape, with a rounded and irregular appearance, with traces of water washing. This reminded Lin of another thing that the world of the lost earth lacked on earth—the open-air hot spring pool.

Don't have hot spring water?

It doesn't matter, use magic to connect to the Otherworld. Magma can be formed, not to mention hot water with a bit of sulfur. This project was done once in the previous planning of the water and sewerage system for the entire tower. This time, I will start from the water elemental plane. Although it is easier to find hot spring water that meets the standards than to look for it from the abyss.

But given the nature of that place, it is unclear whether there will be any adverse effects of soaking in it every day. In addition, if such a hole is opened, it is also unknown whether there will be local residents who will touch the hole. And if you can't be sure, don't gamble on luck, this is the experience of watching countless Earth movies.

What is the law of? 'Whatever can go wrong, it will go wrong'.

Lin Ke didn't want to soak in the hot spring halfway, so he was blown up by the little devil.

As for the overall planning. Even though Lin himself has never been in a few hot springs, he has seen many photos of open-air hot springs, and even made mysterious movies in open-air hot springs. Therefore, after paving the stone slabs and laying the stones to make a height difference, I connected the elemental plane that was suspected to be hot spring water, and got some plants outside the tower to arrange them. After a busy afternoon, although it is not as good as those famous soups in my impression, it is also presentable.
