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.
of numbers.
After Ella came back from the island republic, she copied a copy of the alchemical documents she had memorized in her mind and gave it 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 raised her head 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 bowstring to the maximum was the same whether he was sailing in the direction of 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 breaks away 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 is the cause of movement?" Ella pulled her hair with some annoyance, "I can't figure it 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. Then when I grew up, I understood them all.
Yes. Your Majesty is still young, maybe he will be able to figure it out in a few years."
But Ella didn't seem to hear these words at all, and her expression became more and more troubled. Amy had to find a way to find a topic to distract her attention: "Your Majesty, what are you writing on the paper now? I don't understand.
I have been drawing circles there for several months."
"That's the last lesson I plan to teach the first class of graduates. Amy, you can't understand."
"What, what!" Amy yelled, "Aren't the first graduates all pirates from the Pirate Kingdom? Does Your Majesty think I'm 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 they entered college. In Antilia, Hestein only miscalculated the position of the solar equinox! I see
Amy, the only thing you are better than these pirates is your breasts!"
"Your Majesty, I am 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, and 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? They are 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 side of the object into another.
A kind of opposite. The birth and death of objects will 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 linear motion. The first two are simple motions, and the last one is
Mixed motion. In simple motion, circular motion surrounds 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 composite motion of
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 calculated before in front of Amy. It was also the orbit diagram of the stars, but the number of circles drawn on it was the same as that given to her before.
The piece of paper Amy was looking at was dozens of times larger. And the dozens of pieces of paper below the orbital diagram were densely packed 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 prepared 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."
