These words seemed to have drained away the little strength Yolande had left, and he seemed to have aged several years in an instant.

The rest of the wizards from the School of Prophecy also looked distracted.

Their star map is wrong, and the hundreds of years of efforts of the entire prophecy school have become a complete joke!

"There's no need to be so self-deprecating, Mr. Yolande. In a sense, your star map is still very accurate." Lin En shook his head and said comfortingly.

He was able to confirm that the law of universal gravitation was still applicable in the other world, and that it used the laws of stellar movement that the school of prophecy had spent hundreds of years observing. Lin En was also embarrassed to discourage these wizards who yearned for the starry sky.

"So you finally admit that all this is made up?" a witch from the prophecy school said excitedly.

Lin En glanced at her, speechless. When did he say this?

But before he could open his mouth, Yolande stopped several colleagues who were still trying to continue arguing, and waited for Lin En's answer with a confused look on his face.

Lin En ignored the wizards of the School of Prophecy who had suffered a huge blow and were already somewhat unconscious. He looked at Yolande and continued to speak.

"Remember the carriage problem I told you about? If we use the carriage alone as a reference, the person inside is stationary, but if we use the starting point as a reference, then he is indeed moving. In my opinion, both statements are correct..."

To put it simply, the geocentric theory and the heliocentric theory are based on different reference objects.

Of course, in comparison, the heliocentric theory is more suitable for solving some practical problems. After all, the essence of the formation of a galaxy's orbit is the gravity of stars, so the proposal of the heliocentric theory is indeed a huge progress!

As for whether these people can understand it, that is none of his business.

Amid the discussion, the magic seminar that lasted for the whole morning soon came to an end. However, the topics about planets, stellar orbits, and airship ranging remained as hot as ever.

It was only after they walked out of the seminar that some wizards from top schools suddenly remembered that they had participated in this seminar to showcase the new magic and new theories they had developed.

As a result, they didn't say a word, and the entire seminar became a one-man show by Lynn.

However, under such circumstances, I am afraid that not many people would care about what new magic I have researched. Everyone is guessing how long and how big the planet under their feet is.

Philip was so excited that he could hardly contain himself. Before attending the seminar, he was a little worried that Lynn would not be able to cope with the challenges posed by the wizards of the prophecy school. Unexpectedly, Lynn refuted these people completely in just a few words, and demonstrated the issue of the planet's rotation with an ingenious experiment. He was even nominated for the Corona Medal!

This is the highest award in magical scholarship. He never thought that the Iyeta School would one day be able to receive a glorious Corona Medal. In the past, that was the exclusive privilege of legendary wizards!

Philip was thinking about using magic to call Kevin, Orlando and others to come over to participate in the awarding ceremony. That would definitely be the most glorious day for the Yieta School! Compared to Philip, who was still immersed in joy, Lin En was surrounded by a group of wizards with a burst of curiosity. After getting the method to measure the circumference of a planet, everyone was very curious about how to calculate the mass of a huge star.

Lin En, who was tired of being asked, had no choice but to evade the question by saying that he needed to wait until the radius and gravitational constant of the planet were calculated before he could do further calculations.

After finally sending these curious kids away, Lin En turned to look at the legendary wizard Harof who had not left yet, and asked.

"I still have a few questions, I hope you can give me some advice..." Harof was very humble and did not act arrogantly just because Lin En was only a three-ring wizard.

In fact, this problem has been bothering him for a whole year.

“Please continue to ask, as long as they are questions I can answer.” Lynn nodded.

"I've read the three laws of stars you wrote, but why are you so sure that the orbit of a star must be an ellipse?" Harov asked in confusion. "According to my research on gravity, it is like a water wave, with itself as the base point, spreading out in all directions, and the orbit it forms should also be a perfect circle."

"I have discussed this with some scholars in the Secret Law Society and put forward many speculations, but in summary it can be attributed to two points!" Lin En replied.

"Which two points?" Harov asked quickly.

"First, there is no perfect circle!" Lin En said calmly. "After precise mathematical calculations, pi is an irrational number, so the perfect circle in our imagination probably does not exist in reality."

"That may not be the case?" Harof frowned. The wizards of the Alchemy Society were also studying the curvature of the circle. Although they came to similar conclusions, in his opinion, everything in the world must be regular, but they have not found this law yet.

"Unfortunately, this is the fact. I heard that an adult from the [Secret Society] spent decades calculating pi to two hundred trillion decimal places, but the number he obtained still has no logic and can be deduced infinitely." Lin En shrugged and said directly.

Two hundred...trillions?

Harof was stunned by this terrifying number. He suspected that what Lin En said to him was not the same thing at all, or maybe he had heard it wrong.

He remembered that the Alchemy Association had already deduced the value of pi to which digit. It should be... the ninth digit?

“I don’t remember much, probably only the first two hundred.” Lin En raised his hand and used magic to manifest the numbers.

【3.1415926535897932……】

Looking at the series of complex and confusing numbers in front of him, Harof's face twitched involuntarily. The first nine digits were exactly the same as the values ​​deduced by the Alchemy Association. He had to admit that what Lin En said was probably true.

But how much free time does the other party have to be able to deduce the value to two hundred trillion digits?

At the same time, Harov also admired the other party for working hard on the unsolvable problem of pi for decades just to get a final answer.

Harof became more and more interested in the [Mystical Society] mentioned in the invitation letter. It must be a gathering place for top academic researchers.
