After sending off the guests of the Chamber of Commerce, the Tower of the Great Sage returned to its usual tranquility. After leaving a bunch of trivial matters to his two apprentices, Lin had extra time to think about astronomy.
Astrology was a long-developed field of study in the Lost Earth World. However, the most important part of this field of study was to solve the problem of the two satellites in the sky.
On Earth, there was only one moon, so the tides and weather of Earth would be affected by that one moon.
However, there were two satellites in the Lost Earth World, which caused more complicated changes in the weather system. Weather was related to agriculture and food, so naturally, a specialized profession was born to predict the weather. This profession was called the Astrologer, one of the branches of the Magician.
Among the knowledge that the Magician had to learn, there was also astronomy mixed with occult knowledge. Predicting the weather could only be regarded as a leisure activity. However, for the conscientious rulers, the weather was related to the amount of food harvested in their territory, so naturally, it was not something that could be ignored.
Gradually, some of the magic apprentices who were not talented enough and did not have enough resources gave up the accumulation of magic power and authority, which was equivalent to giving up on the advancement of magic. They turned to serve the lords of the various lands. This was because astrology and weather prediction focused on the aspect of knowledge. The name of the Astrologer was independent from the Magician, and was then despised by the Magician …
It could not be helped, which Astrologer was not able to advance on the path of magic, so they took a step back and turned to the nobles to beg for a living. Therefore, the two professions were dominated by contempt and jealousy, and were not on friendly terms with each other.
However, Lin's main point was that the Astrologers still had some accumulated achievements in astronomy. Just like the star map that he was looking at now, which was bought with a lot of money. The Astrologers in the Lost Earth World were not like the group of scholars in ancient Greece on Earth, who picked out a whole sky of stars, designated them as constellations, and accompanied it with a sentimental story.
There were only four hundred and seventeen stars marked on the entire star chart. The main thing was the orbit and changes of the two satellites across the layout of the star map. This number was far less than the fixed number of stars in ancient Earth, regardless of whether it was Eastern or Western astronomy, which was more than a thousand stars.
Lin Yi felt a little helpless as she looked at the star chart. After all, the circle of astrologers was more closed than that of magicians. Perhaps it was due to their inferiority complex, but astrologers tended to treasure the knowledge they had researched and were rarely willing to share it with others.
The map that Lin Li had bought was an amateurish version compiled by a mage. It had more stars than the standard version provided by the association. But Lin was still disappointed.
For the past few nights, his main job was to fill in the blanks of his own star map, a flat version. The most difficult part was to determine a North Star as a reference. Only then would it be convenient to draw an accurate star map.
Because of the Maze World, most people who studied astronomy focused their attention on the two satellites. In addition, God Spirits really did exist. There was a saying that exploring space was spying on the God Kingdom, which would offend God Spirits. Therefore, most people kept their research in this area a secret, so they had to do a lot of work themselves.
Thinking of how much work he had to do, from the time of the Greek philosophers to the time when the general theory of relativity was established, made his scalp tingle.
On Tripwood's version of the star chart, there were nearly two thousand stars. Now, Lin Li began to consider another matter, which was how to measure distance.
The most primitive parallax method had to be measured in two places, so it was basically abandoned. As for the radar method that used the principle of sonar, looking at the pure and unpolluted sky outside, he directly gave up on the idea of adding radar technology.
The more feasible methods were the many derived methods from the annual parallax method and the phenomenon of red shift. However, the accuracy of these methods depended greatly on the precision of observation. Just finding a way to measure the angle of one second (1/3600 of an angle of one degree) with the existing equipment and magic knowledge available would kill countless brain cells.
Also, in order to use the annual parallax method, he had to re-measure the Maze World version of one astronomical unit. That was the average distance between the Maze World and the sun. As a result, the radius of the Maze World, as well as the revolution, the rotation period, and even the unit of time, had to be accurately measured or defined again.
Thinking of this, Lin Li had to think about the star chart on the wall of the restaurant again. It was one of the few things in the Tower of the Great Sage that had been handed down since the beginning of its construction. It clearly showed the star system where the Maze World was located. This also proved that the people in the Maze World had abandoned geocentric theory and entered the heliocentric theory that was closer to reality.
On the star chart of the star system, although the distances between the planets were not correct, and they were generally used as orbits in concentric circles of equal distance, the orbital period of the six planets was very accurate.
Among other things, just the fact that the star chart had operated for thousands of years, and now the position of the six planets on the star chart was almost the same as the actual result of Lin's observation, showed how amazing the astronomical achievements of thousands of years ago were. Then, there was no progress for thousands of years … It was similar to the problem of a country that claimed to have a civilization of five thousand years.
Lin Li also wanted to study the operating principle of the star chart. However, the results of the actual investigation only confirmed that the magical principle behind the star chart was very complicated, and it could not be sorted out in a short period of time.
In addition, most of the energy channels were concentrated at the position of the star chart, so Lin did not dare to rashly change or cut off the energy supply here. When the magic tower was being rebuilt, when the tower was not clear about the situation, there was a blackout, and he accidentally found that the star chart could continue to operate, and it was supplied with energy from an unknown source.
All kinds of wonderful things made Lin decide to keep the star chart and maintain its original appearance for future research and comparison purposes. Of course, the subsequent renovation of the magic tower also bypassed the energy supply of the star chart to maintain the continuity of its operation.
Incidentally, the phenomenon of six stars in a row would occur in the next one or two years. That is, six planets in a line. This phenomenon, in the ancient times of Earth, would always be some kind of astronomical warning, so much so that in modern times, it was also the subject of a novelist's book.
However, on Earth, Lin Li only encountered the seven stars in a row in 2000 AD. He did not know if the political changes in Taiwan counted as an impact. Apart from that, nothing much had happened. The main reason was that the orbits of the planets were not on the same plane, but a slight angle deviation, so it was impossible to completely connect them in a straight line in three-dimensional space.
Then there was the part of calculation. The reason why the computer in another world was created was to simplify the calculation process. Think about it, before NASA introduced the computer from IBM, they had a whole team of calculators. The mathematical talents in the maze world could be described with a simple word: none. In a world where even multiplication did not exist, what could one count on?
It was not complicated to use a computer to do calculations, but the difficult part was the accuracy of floating point numbers. The most primitive computer, in terms of decimal point error, lost to manual calculation. This was limited by the data structure and the normalization of numerical values.
The program improvement in this area was to use arrays to deal with it. Before transmigrating, various programming languages had been developed and used as examples, but those were all based on binary …
In the maze world, the octal computer based on the eight magical powers had to have corresponding conversions for the relevant theories. This caused a certain someone to lose a bunch of brain cells.
In short, since settling down in the Tower of the Great Sage and officially beginning to explore the stars and find a way home, a certain someone had been constantly breaking down and recovering. And this was one of the reasons why he bought so many materials from the Chamber of Commerce.
Apart from some ideas in his mind, he wanted to try them out. When a person was breaking down, he went into the forging room and knocked on it, as if it could help him come back to life. And by making a finished product, it could more or less make up for the frustration of astronomical exploration.
And on a certain afternoon when he had a breakdown, simply knocking on the wall was not enough to restore his brain to its original state. Under the strange gaze of the two girls who looked at him as if he was a walking corpse, Lin seemed to float into the warehouse on the first floor.
His lifeless eyes looked for materials that could touch his nerves, and the stones piled up in the corner were high-level stones used to build the walls of the Magic Tower. Originally, Lin had the idea of completely repairing the Tower of the Great Sage, but he had to maintain consistency to maintain the overall energy balance.
Unfortunately, the Tower of the Great Sage had been built for thousands of years. Although the technology was outdated, the materials were top-notch. This kind of stone called green vortex stone was not only rare, but the known veins had been mined out. In other words, there was no place to buy it even if you had the money.
These stones were the only ones in the Sijia District branch's inventory, provided for some rich Mages to make important parts for golems. And this amount of stones couldn't even erect a wall.
A while ago, when the manager of the Chamber of Commerce came to visit, Lin did mention this issue. As a result, the other party gave him a bad idea – how about demolishing other people's towers?
…
After the two of them were speechless, this matter was never mentioned again.
Now looking at this pile of stones that were neither high nor low, an idea came to Lin's mind.
Without calling anyone else, Lin bared his arms and only used Potency to carry these stones to the open platform on the second floor alone. This kind of stone, as the basic material of the Magic Tower, had a major characteristic of high density, heavier than iron for the same volume. So even though Lin helped himself with Potency and carried all the stones to the second floor, he was still sweating all over.
Because this kind of stone was rare and precious, there was no unnecessary reduction for the convenience of transportation. Instead, it maintained its original shape, a round and irregular appearance, with traces of water erosion. This reminded Lin Xiang of another thing that the Maze World lacked on Earth – an open-air hot spring.
No hot spring?
It didn't matter, rely on magic to connect to another plane. Even magma could be made, not to mention hot water with a little sulfur. This project was done once before when planning the water and sewage system of the entire tower. This time, it was done again from the Water Elemental Plane. Although it may be easier to find hot spring water from the Abyss.
But considering the characteristics of that place, it was unknown whether there would be any adverse effects of soaking in it every day. Moreover, if such a hole was opened, it was also unknown whether the local residents would come through the hole. And if you can't be sure, don't bet on luck. This was the experience of watching countless movies on Earth.
What was Murphy's Law? "Anything that can go wrong will definitely go wrong."
Marco Lin didn't want to be raped by an imp halfway in the hot spring.
As for the overall plan. Even if Lin himself hadn't soaked in many hot springs, he had seen a lot of photos of open-air hot springs, and even riddles made in open-air hot springs. So after laying the stone slabs and stacking the stones to make the difference in height, he connected to the Elemental Plane suspected to be the hot spring and brought back some plants to decorate the tower. After a busy afternoon, although it wasn't as good as the famous soups in his impression, it was more like it.
