As Amy said, this "trial" given by Dust is a rare free time for Ella.
Ella is very busy most of the time, especially in the dead of night. After dealing with government affairs for the day, Ella will spend several hours in the study, dealing with piles of manuscript paper that only she can understand. number.
After Ella returned from the Island Republic, she copied a copy of the alchemical documents she had memorized in her mind to Paracelsus, and then she never touched alchemy again. In Amy's impression, in addition to processing those numbers, she always held the "Eye of Hermes" made by her and looked at the stars all night long.
At this time, Amy could feel that the Ella whom she complained about as "absolutely depraved" was still the same Baselisa she once was.
"Your Majesty, don't you study something more interesting?"
Amy asked after bringing Ella an evening snack.
"Interesting things?" Ella looked up from behind the stack of books, "What do you mean?"
"Previously, His Majesty fired a slingshot on Najirfa. As a result, the distance the slingshot was shot after pulling the bow string to the maximum was the same whether he was sailing in the direction facing Najirfa or against the direction of Najirfa; also, If you throw a stone upward on a speeding carriage, the stone will fall back into your hand instead of being thrown behind by the carriage; also, if you lower the sail when a long ship is sailing quickly, the sail will fall directly under the mast instead of being thrown behind by the carriage. Directly behind the mast, these results are quite incredible and interesting..."
"It's incredible. These results show that whether it is a sail or a stone, it is still moving forward at the same speed as the ship and carriage when it is separated from the ship and carriage. It is obvious that it does not experience any force after breaking away... But It's not fun at all! Force is not the cause of movement, so what exactly is the cause of movement?" Ella pulled her hair with some annoyance, "I can't figure this out, so I can only avoid thinking about it for the time being. It. When you mention it, Amy, my head starts to hurt again!"
Seeing that Ella was about to pull her hair off, Amy quickly stopped her and said, "Then don't think about it for the time being! When I was a child, I just ignored things that I couldn't understand, and then I understood them all when I grew up. Yes. Your Majesty is still young, maybe you can figure it out in a few years?"
But Ella didn't seem to hear these words at all, and her expression became increasingly distressed. Amy had no choice but to find a topic to distract her attention: "Your Majesty, what are you writing on the paper now? I see that you have been drawing circles there for several months."
"That's the last lesson I plan to teach the first class of graduates. You can't understand it, Amy."
"Wha, what!" Amy shouted, "Aren't the first graduates all pirates from the Pirate Kingdom! Does Your Majesty think I am not even as good as these barbarians?"
Ella raised half her eyes from the table and asked, "Amy, what is that thing that goes around us in the sky every night?"
"Five gods! They are Aphrodite, Hermes, Ares, Zeus..."
"So Amy, you don't understand at all! Those pirates were already able to calculate the trajectory of the planets before entering college. In Antilia, Hestein only miscalculated the position of the solar equinox! I see Amy, the only thing you’re better than these pirates is your breasts!”
"Your Majesty, I'm not convinced when you say that! I also know the laws of the gods very well!" Ella's provocation made Amy forget her original purpose, brought a stool and sat down in front of Ella angrily. , "Your Majesty, why did you ask those pirates? Just ask me here! It took those stupid pirates several years to graduate, but I can answer it right now!"
"Well... okay then."
Ella took out a new piece of manuscript paper and began to write and draw in front of Amy.
"First of all, Amy, those five planets...just think of them as five gods. How do they move in the sky?"
"It's so simple! With the earth we are standing on as the center, the five gods, plus Apollo and Artemis, are all making circular motions around the earth!"
"Wrong. It's not the center. Our earth is a little off from the center. These 'gods' move in an eccentric circle. Otherwise, it would be completely inconsistent with the observed data." Ella looked at him with pity. Amy, "This is knowledge that people in the Qiqiu Empire knew seven hundred years ago? Seven hundred years behind, Amy, you are actually a barbarian..."
"It's just convenient for Yuan to say it! Isn't it more or less the same? Your Majesty can only mingle words on such small details?"
"Okay, Amy, second question: How to prove that these celestial bodies are moving in a circular motion?"
"This...doesn't this need proof?"
"Of course it needs to be proved. Aristotle made a very simple proof. He said that the birth of things is due to the existence of some kind of opposition in the object itself, and the destruction of things is due to the transformation of one opposite of the object into another. A kind of opposite. The birth and death of objects only appear when there is opposition in the object. And celestial bodies are immortal, so celestial bodies do not have any opposites. Anything that is neither born nor destroyed excludes any opposites. .”
"That's right!" Amy agreed, "There is no opposite, no increase, no decrease, no change, no change, so the celestial body is eternal. And only gods are immortal and eternal..."
Ella ignored Amy's words and continued: "Then Aristotle pointed out that there are only three types of motion, circular motion, linear motion, and mixed motion of circular and straight lines. The first two are simple motions, and the last one is Mixed motion. In simple motion, circular motion goes around the center, and linear motion leaves the center or approaches the center. Leaving the center and approaching the center are obviously opposites. Since a celestial body does not have any opposites, it can only move in a circular motion. "
"Aristotle is so awesome... No, not awesome at all! Gods move in circles around our world. This is something that doesn't need to be proven at all! Isn't it?"
"No need to prove it? Amy, you should also know that sometimes, these celestial bodies will suddenly appear retrograde in the sky, right?"
"Oh...it does happen. Maybe the gods are angry..."
"Except for you, any pirate from the university can explain this." Ella sighed and drew a schematic diagram for Amy on the manuscript paper, "It is true that it is a circular motion, but it is multiple circular motions. The compound motion. The large circular orbit is called the 'deferent wheel', and the small circular orbit is called the 'epicycle'. This is the system established by the astronomer Ptolemy of the Seven Hills Empire seven hundred years ago. As long as the uniform wheel is Adding a few epicycles to the outside of the wheel can explain all the celestial motion phenomena observed at that time. Based on this theory alone, it is not an exaggeration to call Ptolemy the 'lawgiver of the sky'."
"Well... this... I have never learned it, but I have learned it now!" Amy argued unconvinced, "It only took me a few minutes, but those pirates have been learning for several years! I am much smarter than them. Got it!"
"Learned it? Are you sure?"
Ella took away the manuscript paper given to Amy, and then piled the pile of information she had been calculating in front of Amy. It is also a star orbit diagram, but the number of circles drawn on it is dozens of times that of the manuscript paper shown to Amy before. As for the dozens of pieces of paper below the orbital map, each one is densely written with Ella's observation records of celestial bodies.
"Using the Eye of Hermes, I greatly increased the accuracy of astronomical observations. At this accuracy, epicycles and deferents of Ptolemy's number could no longer explain the results of the observations. I had to add new ones. Epicycles are used to fit the observation results. Just now, I have increased the number of epicycles to seventy-six. And then there are my new observation records, which also have some interesting things... Amy, How long are you going to spend learning this?"
"This... Your Majesty! Why do you make it so complicated!"
"Stupid Amy."
Ella sighed again. She was not happy about winning the argument, but seemed a little disappointed.
"There is a chance to become a great elf, or even an elf king, hidden in my observation data... If you can be a little smarter, Amy, I will teach it to you."
