Game of Thrones: Viserys the Three-Headed Dragon.

Chapter 217: Academy Meeting
The underlying science of the Ice and Fire world has a lot in common with that of Earth. For example, the circumference of the Ice and Fire world is also 360 degrees, and the advantage of this artificial number is that it can be divided by 2, 3, and 4.

With this underlying logic, it is much easier for PhD students in the Citadel to understand the geometry in "Elements of Geometry".

Viserys's knowledge of geometry was limited to high school level, and the "Elements of Geometry" he compiled "from Valyria" only talked about the simplest primitive concepts and propositions of points, lines, planes, circles and parallel lines. Only the six volumes of content that were severely castrated and had many omissions in Viserys's mind.

第1卷用多个定义提出了点、线、面、圆和平行线的原始概念，提出了多个公设和公理，研究了三角形全等的条件、三角形边和角的大小关系、平行线的理论、三角形和多角形等积的条件；第2卷研究多边形的等积问题；第3、4卷分别讨论了圆的问题及圆的内接和外切多边形；第5卷详细探讨了关于量的比例的理论；第6卷为相似多边形的理论。

With the blessing of the dragon, Viserys's memory of elementary and high school geometry was limited to this.

However, although this book "Elements" which uses axiomatic method to establish deductive geometry knowledge has many omissions, it undoubtedly summarizes a very convincing mathematical logic system from scattered and fragmentary empirical forms, and much of the knowledge coincides with the knowledge system in the academy.

Even because Viserys simply ignored the process and threw out the method and answer, such as calculating pi by dividing the circle, the final result written directly in the book was more accurate than the one here in the Citadel.

Viserys threw this thing out, of course, in preparation for taking over the Citadel.

Viserys planned to use several large-scale and eye-catching academic experiments to mobilize the doctors in the Citadel, transfer these people out of the Citadel and separate them geographically. He would then move into the Citadel in the name of academic research, in the hope of eventually defeating these suspected secret organization members one by one.

Digging out the cancer was not something that could be done by sending troops to the Citadel, arresting people, torturing them, burning books, and burying scholars alive. Viserys intended to portray himself as a friend of science and his opponents as enemies of science, in order to cut off the soil that would continue to breed this cancer.

Since Master Marwyn offered to help, Viserys certainly wouldn't hesitate.

These methods have always been used to incite people.

Viserys sent out Professor Marwyn to stage an "Asshai scholar challenging the Citadel" drama, and he was not afraid that these scholars would not take the bait.

And just as Viserys expected, when his men arrived at the Citadel with the Elements of Geometry, a sea monster dissection plan, and the blueprints of several feasible geographical experiments, these things quickly caused a stir among the doctors in the Citadel.

When Chancellor Theobald convened an emergency meeting and summoned many doctors in the academy to discuss the matter, the three great physicians, Dr. Ambrose, Dr. Moras, and Dr. Osri, who had made great achievements in anatomy, all expressed their very eager hopes.

In addition to PhDs in history and philology.

The doctors of mathematics and astronomy, led by Dr. "Vinegar" Verin and Dr. "Silent Stargazer" Colin, also expressed great interest in the several planetary measurement experiments proposed by King Viserys.

In particular, for the experiment of measuring the circumference of the world, Viserys proposed a measurement method called "Eratosthenes Method", which combines astronomy and geodesy, observing the position of the sun in a day at Oldtown and one hundred leagues due north of Oldtown, and calculating the circumference of the world based on the difference in the length of the shadows of the objects.

This method requires digging a deep well in Oldtown and erecting a tall pillar a hundred miles north of Oldtown.

By measuring and recording the shadow lengths of the wells and pillars and the angles of the sun's rays on the same day or multiple days, it is possible to measure the angles formed between the upright pillars, wells and sun's rays at the same time.

After obtaining these data, the mathematical law in geometry was applied: when a ray passes through two parallel lines, their opposite angles are equal. In this way, the angle produced when the sunlight shines parallel to the two places at the same time can be obtained through the angle difference obtained. From this, the arc length corresponding to this angle can be obtained, that is, the distance from the old town to 360 leagues should be equivalent to the angle difference divided by of the world's circumference. Once this result is obtained, the circumference of the world can be calculated by mathematical methods.

And knowing the circumference, we can know the radius and diameter of the world ball.

Of course, the premise of all this is to assume that this world is indeed a spherical planet.

In addition, King Viserys also proposed a method to verify whether the world ball itself is rotating, that is, to use a spherical pendulum loaded with a gyroscope to swing naturally in a straight line on the sand table to see if the trace it leaves on the sand table is a constant line.
Also, drop two iron balls of different weights from a high tower and see if they land at the same time.
Even the doctors who attended the secret meeting had complicated thoughts when they saw these feasible experiments: "His Majesty Viserys is a knowledgeable and wise king. His Majesty is willing to take the initiative to find the Citadel to conduct these cooperative experiments. It shows that he is very supportive and recognizes the academic research of the Citadel, right?"

Dr. Theobald raised his eyebrows. "What do you want to say, Colin?"

".I mean, we can cooperate with King Viserys, right? If he becomes king, it will undoubtedly provide a lot of help to the Citadel's research—" Theobald interrupted him: "Ahem, today we are only talking about these cooperation projects proposed by the Targaryen King."

Colin shut up.

Vinegar Vaelin continued, "These experimental plans are very feasible, and the book. I dare say that the king must have been to Valyria, and he must have more knowledge in his mind that is very useful to us."

Theobald said, "What is his purpose in studying this?"

Colin couldn't help but say, "Just as the Asshai he sent said, he wants to verify what he learned in Valyria, doesn't he?"

Historian Gallardo said: "The Valyrian tomes collected in the Citadel never contain any textual records of these experiments sent by King Viserys. I say, why do you all think that this was a good intention proposed by King Targaryen? There is no such thing as free bread in the world."

Doctors of mathematics, doctors of astronomy, and great physicians all looked at Gallardo. Vinegar Verin sarcastically said, "This is a serious academic question, and you are a historian, Gallardo, you don't understand."

Gallardo frowned, "What happened to the historian?"

Weilin replied: "I am not looking down on you, Gallardo. I thought you could at least understand the feasibility of these academic projects and how constructive the expected results are. But I can understand that compiling historical texts takes up a lot of your time, leaving you no time to study other things."

Gallardo stood up angrily: "Welin!"

As a representative of history, Dr. Perestan began to smooth things over: "Dr. Weilin, history is as important as all other academic disciplines. Studying history allows us to learn wisdom and lessons from it."

Dr. Osley asked, "Oh, really? Does the wisdom of history tell you what to do when a frozen sea monster specimen is delivered to the gates of the Citadel? Reject it?"

Dr. Perestan responded: “History has taught me that there is no free bread.”

Colin said, "King Viserys needs us, there is no doubt about that. He wants us to help him verify the knowledge of 'Valyria' that he cannot verify on his own. Look at these experiments, these ideas need people with knowledge and wisdom to operate them, in order to get the most convincing results. This is a win-win cooperation. Why not?"

Another doctor of history, Benedick, said, "The fact is, we cannot refuse. Steward Theobald, even if we refuse these things, King Viserys will find someone else to do them. And what can we gain from refusing the king's Citadel? It is distrust and vigilance. The king needs the Citadel and values ​​it. Isn't this a good thing?"

Theobald finally couldn't help but say, "I don't deny the constructiveness of these academic experiments, but White Walkers, wights, murlocs, dragons and sea monsters, magic and witchcraft? These things will be widely publicized with the arrival of Targaryen and the cooperative experiments with the Citadel."

Dr. Nemos couldn't help asking, "Aren't these facts? Dragons and sea monsters have already appeared, and as far as I know, the letter from Maester Goras of Stormland mentioned 'fishmen', and the news from Dragonstone mentioned the appearance of White Walkers in Braavos. I mean, are we going to deny these facts and forbid the spread of these news?"

Everyone looked at him, and Dr. Nemos' scalp tingled: "I just want to say that we should respect reality, right?"

"Doctor Nemos, do you remember what brought back these unnatural magic and witchcraft? Do you remember the oath you made?"

Nemos swallowed and said, "Of course I remember."

Doctor Theobald said coldly, "Then don't say such foolish things." Then, Steward Theobald said, "Doctor Benedick is right. Things have come to this point. We cannot refuse any request from King Targaryen. I admit that His Majesty Viserys may be a wise and knowledgeable king, but I believe that most of his wisdom and knowledge are biased. He has gone too far on the wrong path, and the human beings who may affect the whole world are once again in crisis. Because of him, the efforts made by the predecessors of the Citadel a hundred years ago have been destroyed.

Fellow travelers, the situation in the Citadel has reached a critical moment again. We must pledge allegiance to the rule of the Targaryen family, just like our ancestors three hundred years ago. However, we must also be like our ancestors a hundred years ago, with perseverance, wait for the opportunity, and be ready to correct the kingdom's steps on the wrong path.

This is not out of selfishness, but for the bright future of the whole world!"
