The memory was completely shattered, and new images began to load.

*************

"He who seeks knowledge is not guilty."

In a slightly modern cave, the environment is in sharp contrast with the outside world.

The space here has been transformed into a classroom by [Miguel Set] using its magical abilities. The classroom has complete facilities and is equipped with the latest teaching tools, showing that the [Miguel Set] race is understanding and imitating human culture.

extraordinary abilities.

"I remember when I was a child, the teacher wanted to keep the students in the class busy for a while, so he gave a seemingly tedious math problem: calculate the sum from 1 to 100. The teacher expected that this task would be enough to keep the children busy.

time, since it seems like a lot of addition operations need to be done.

However, I found an easy workaround almost immediately.

Instead of adding up one by one like other children, I used a clever method: I found that the 100 numbers from 1 to 100 can be paired, and the sum of each pair is 101 (that is, 1 and 100, 2 and 99,

3 and 98, and so on), there are 50 pairs of such numbers in total.

So, we quickly figure out that the answer is 50 times 101, which is 5050.

You see, this is mathematics, how beautiful it is!"

Pedro stood in the front of the classroom, with a blackboard in front of him showing carefully prepared teaching content.

The diagrams and text on the blackboard are clearly visible, and they were obviously carefully prepared by the young man in advance.

The interior decoration of the classroom is simple and modern, with moderate lighting. Some images of the [Migelset] race and their symbols are hung on the walls.

Pedro has established a friendship with the creature in front of him. He has known him for almost half a year.

Today, he was teaching each other interesting mathematical formulas as usual, and the other party was already his student.

However, today, his students will prepare a big surprise for him.

"The formulas and laws you gave me are very interesting, Pedro."

Below the classroom, a transparent creature is squirming. There is a pen floating in front of it. At the moment, the pen is writing and drawing on the paper in front of it.

Soon, a unique black and white painting was drawn on the pen.

"Pedro, look, this is the system I deduced based on the formula."

Pedro took the paper handed over by the transparent creature and looked at it carefully.

The paper depicts a model of the geocentric universe, in which the Earth is at the center and is surrounded by a series of concentric orbits representing different celestial bodies such as planets and stars.

These orbits represent the paths that the other party believes the celestial bodies are traveling.

The style of the picture is similar to old scientific illustrations, with a classical and retro atmosphere.

"This is……"

Pedro looked at the content on the picture and was speechless for a moment.

He was very familiar with the content of the drawing in his hand. It was the wrong path Terra took in astronomy.

This is the Ptolemaic system.

That is the very beginning - the geocentric theory.

"I don't think the world is a dream. The world under my feet is round. There is no doubt about it!"

The pen floating in front of the transparent creature is shaking violently. From this, we can see the inner excitement of the operator.

"As you said, we stand on the earth relying on a certain weight, so I think it is caused by the sphere under our feet, and there is also a certain attraction between the spheres."

The paper floated and suspended from Pedro's hand, and the transparent creature came to the paper, opened its teeth and claws, and shared its discovery with Pedro with great excitement.

"The sphere beneath our feet is stationary, and all celestial bodies, including the sun and stars, rotate around the sphere beneath our feet."

"However, the planet only orbits the sphere under our feet in circular motion, which is not enough to fully explain the diverse movements of the planet. So I came up with the idea that an imaginary small circle (rather than the planet itself) is orbiting the earth in a circular motion, and the planet

It just moves on this small circle. This small circle is called an epicycle, and the orbit of the epicycle around the earth is called a deferent, just like what is shown in the picture."

He was so excited and so happy.

So much so that he was unable to detect the flash of pity and intolerance in Pedro's brown pupils.

"This is the formula, Pedro, look at it."

A new graph appeared out of thin air again, and four lines of formulas appeared on the paper.

[The coordinate formula of point P on the deferent wheel is:

x_P = R * cos(omega_d * t)

y_P = R * sin(omega_d * t)

Where R is the radius of the deferent, omega_d is the angular velocity of the deferent, t is time, cos and sin are cosine and sine functions.

The coordinate formula of the planet on the epicycle relative to point P is:

x_pla = x_P r * cos(omega_e * t)

y_pla = y_P r * sin(omega_e * t)

Where r is the radius of the epicycle, omega_e is the angular velocity of the epicycle. Here x_P and y_P are the coordinates of point P on the deferent wheel, and cos and sin are also cosine and sine functions.】

"Through the formula, we can get this graph."

A model appears on the paper, in which several orbits can be seen, representing the compound motion of the planets on deferents and epicycles. The red mark in the figure symbolizes Terra, as the moving

center point.

Terra is the center of the universe, around which other celestial bodies such as the sun, moon and known planets orbit the earth.

These trajectories are attempts to explain the complex observed motions of celestial bodies relative to the Earth.

In the model, the planets first move around the epicycle, and the epicycle itself moves around the deferent, and the center of the deferent may not exactly coincide with Terra. This is how he explained phenomena such as planetary retrograde motion.

"Pedro, the world is not a dream, there is never any hidden god!"

"The world can be observed, the world can be predicted, the world can be touched!"

The transparent creature said to Pedro seriously.

Pedro looked at the transparent creature in front of him, his Adam's apple squirmed, and he was about to say something, but the words he originally wanted to correct turned into a question that he found incomprehensible.

"In our race, students love their teachers. I want to ask you, if the knowledge your teacher teaches is wrong, or you don't agree with your teacher's ideas, will you still love your teacher?"

The transparent creature first tilted its head and looked at Pedro strangely.

Then, he thought seriously for a moment and replied:

"I love my teacher, but I love the truth even more!"

"..., Galilei."

"What?"

"This is the name I gave you. Galilei, this is your name. The name is very important to a civilized individual. It will serve as an identifier of the individual. It is the basic expression of a person's identity.

It distinguishes the individual from others, providing each person with a unique symbol or label through which we become ourselves.

Names carry personal history and connect individuals and society. Names are a reconstruction of reality.

Finally, you have to remember that names are given by others, but individuals should define their own existence through their own choices and actions."

Pedro said to Galilei very seriously.

He knew that when he gave the other party the name Galilei, he was on a path of no return.

He found a fellow traveler for himself, even if the other person was not human.

He needs a partner so much.

Iberia needs change, Miguelset needs to emancipate its minds.

Changing the world does not happen overnight, so he chose to start by changing his individual destiny and himself.

After Galilei received the name, he used his vocal organs to repeat the name Pedro gave him in Terran Common:

"Ga...li...lue?"

"It's Galilei, although the pronunciation is the same."

"Does he have any moral meaning?"

"..., maybe there is."

Pedro and Galilei began to have wild conversations, which they were used to, and their conversations were always full of leaps and bounds.

"Pedro, is my theory correct?"

"This is the theory you discovered. What do you think?"

"It's weird, it's too complicated. I think it should be simpler and more perfect!"

"Maybe, no matter what, it's still spinning."
