After Calvin adjourned the meeting, quite a few scholars had already stood up and were ready to leave.

The sound of "wait" made everyone's movements pause, and their eyes looked at the corner in unison.

Chen Luo had long been accustomed to being watched like this by everyone, and under the gaze of these honorary scholars, he slowly stood up.

"Blair ......" ahead, Britney looked at her, a look of surprise on her face.

When he heard that familiar voice, Calvin's body was shocked, and a glimmer of hope welled up in his heart.

Although Blair is known as the devil of mathematics, he has always been a person who can perform miracles, and if there is anyone in the city of Arpo who can stop the footsteps of those Gaya scholars, except for "Roselle", who has not appeared for a long time, it is the devil Blair.

Although the trace of God is hard to find, the devil is all around them.

Calvin walked quickly to the corner, looked at Chen Luo with burning eyes, and asked, "Your Excellency Blair, do you have a way?"

After living here for so long, Chen Luo still has some emotions for the Luolan Kingdom.

He is an honorary scholar of the Kingdom of Loran, and those Gaya scholars who slap the face of the mathematical community of the Kingdom of Loland are slapping him in the face.

What's more, the matter was originally caused by him, and the aftermath should also be handed over to him.

Originally, he planned to offer a low-key anonymous reward to help Apor City and Lorain save some face.

After hearing Calvin say that the kingdom would reward him with 5,000 gold coins, Chen Luo knew that he couldn't keep a low profile anymore.

As long as the money is enough, even if he is a university scholar, Chen Luo will still teach him to be a man.

Chen Luo didn't answer Calvin's question directly, looked at him and asked, "As long as you can stop those Gaya scholars, the kingdom will offer a reward of five thousand gold coins?"

After speaking, he added: "Of course, it doesn't matter if the gold coin is not gold, the important thing is that I am from the Luolan Kingdom, and it is my bounden duty to protect Luolan and maintain the glory of Luolan." ”

"If you can stop them, you will receive five thousand gold coins from His Majesty's reward. Calvin nodded without hesitation and said: "This is the news that has just come from the kingdom, His Majesty the King is also very concerned about the affairs of Apo City, if they are allowed to leave Apo City like this, from now on, the Lorraine math community will become a joke......

If a country's mathematical community is solved by a visiting mission from another country, all the bounties are solved, and all the bounties are taken, once such a thing happens, the mathematical community of the Kingdom of Luolan will no longer be able to raise its head.

Calvin thought for a moment and added: "Your Excellency Blair, Lorraine wants to win, and he must win with dignity, and he can't maliciously make things difficult for Gaya's visiting scholars. ”

"Yes. ”

Chen Luo nodded, it is not easy to make things difficult for the other party, let them make a positive 10,000-sided shape within half a divine grace, but in this way, it is still Luo Lan's face that is lost, not only can not save his dignity, but he will also be considered by other countries that he cannot afford to lose.

The questions they ask must be of research significance, theoretically achievable, recognized by all scholars, and valuable.

It's best to look at anyone who can, and I can do it, but when you start to doubt, the classic questions of life.

For this kind of problem, Chen Luo can publish a book.

Chen Luo looked at Calvin and said, "It's not a problem to let those Gaya scholars stop in Arpo City. ”

Calvin exclaimed, "Really?"

"But I have one condition. ”

Calvin hurriedly said, "Lord Blair, please speak." ”

At this time, let alone a condition, even if it is ten, a hundred, as long as it can solve this urgent need, Calvin will not hesitate to agree.

Chen Luo looked at the other side and said, "Let Able Howard give me fifty gold coins." ”

Calvin was stunned, not knowing what this meant.

If he could really help the Apo City branch through the difficulties, even if he asked for another five thousand gold coins, the scholars of the Loran Kingdom would help him get them together, but he only needed fifty, and he appointed Able Howard.

This Lord Blair has the name of the devil, and his actions are indeed unpredictable by ordinary people.

Able was also surprised for a moment when he heard Chen Luo's words, and then said with a smile: "If Your Excellency Blair can restore the glory of Lorain's mathematical community, Abel is willing to give you five hundred gold coins." ”

Chen Luo shook his head and said, "I only need fifty." ”

He is still principled in life, and the fifty gold coins are his, even if he wins the five thousand gold coins of the kingdom, he still loses the fifty gold coins, and he loses the gold coins that belong to him forever......

Chen Luo didn't want gold coins, but thoughts.

Able looked at him and nodded, "I agree." ”

Chen Luo looked at Calvin and said, "Bring the paper." ”

A deacon had already brought the pen and paper that had been prepared.

Chen Luo quickly wrote a few lines on the paper and handed it to Calvin.

Calvin and the scholars around him looked at him impatiently, and after a moment's pause, a blank expression appeared on their faces.

It's not that these questions are too difficult for them to have a clue, but it's too easy.

It's so simple that it's hard to believe that this is the Edwin Prize winner's proposal.

There are three questions on the paper, all of which are ruler drawing problems.

The so-called ruler and compass, is no scale ruler and compass, as early as hundreds of years ago, the ancestors of the mathematical community found that the use of no scale ruler and compass, can draw a variety of geometric figures that meet the requirements, later, the ruler and compass drawing has formed a fashion in the mathematical world, mathematicians are immersed in the use of the compass and the ruler without the scale of the drawing, and called the ruler and gauge drawing method.

These three rulers are used as drawing questions, and each question has only one sentence.

Divide any given angle into three equal parts.

Find a square equal to the area of the circle.

Find the edge length of a cube so that the cube is twice the volume of a known cube.

On the surface, these three questions are too simple, and according to their experience and intuitive feelings, this is almost the simplest kind of ruler drawing problem.

Calvin was also worried that Chen Luo would raise extremely complicated, time-consuming and laborious questions to embarrass the Gaya scholars, which would make the Kingdom of Loran a joke.

He never imagined that the question he asked would be so simple.

He looked at Chen Luo and said unconvinced: "Your Excellency Blair, are you serious?"

Chen Luo smiled and said, "You can try it first." ”

The three equal angles, the circle into a square, the cube, are the three famous classical problems of ancient Greece, these three questions are wonderful, they look very simple, there is no bit of bells and whistles, one sentence can be described, but when you really do it, you will find their horror.

These three classical problems were proposed in ancient Greece BC, and since they were proposed, mathematicians of every era have tried to come up with perfect solutions to these three problems.

It wasn't until more than 2,200 years later that mathematicians proved that these three seemingly outrageously simple problems were impossible to solve with a ruler and compass alone.

They are also known as "ruler drawing can not be a problem".

For more than 2,000 years, generation after generation of mathematicians have tried their best to overcome the three major problems, and some people have questioned the significance of these three problems.

What they don't understand is that this is actually the romance of classical mathematicians.

Mathematical research does not have to be practical, mathematicians must figure out every unknown mystery, and this spirit of stubbornness is the spirit of science.

More importantly, countless mathematicians, in the process of trying to accomplish this impossible thing, have made countless breakthroughs, discovered some new mathematical ideas and methods, and provided more valuable parts of Greek mathematics and modern mathematical thought.

Every breakthrough they make is a victory of human wisdom, and they will bring some new ideas and new methods to the world, which is where the value of these three problems lies.

Calvin asked him to provide questions that looked simple, could stump the Gaya scholars, and were valuable, so Chen Luo had to move them out.

As for some other well-known problems, they either cannot be completed in a short time at first glance and have the intention of making things difficult for others, or they are too modern, and when many mathematical concepts have not yet been proposed, the mathematicians here may not understand the problems and are not suitable for taking them out......

Naturally, the Mathematical Society did not need a ruler as a tool, and these honorary scholars simply sat back in their seats and answered these three questions in the conference room.

In their opinion, with so many honored scholars present, such a simple question should have a quick result.

However, this sitting is a dozen divine grace hours.

It was already the middle of the night, and not a single scholar in the conference room of the Mathematical Association had gotten up.

It was late at night, Chen Luo yawned, pushed the door and walked in from the outside, walked up to Britney, handed her the cream cake he had just bought outside, and said, "Teacher Britney, let's eat something." ”

When these scholars challenged the three classical questions, of course he would not wait here stupidly, he went to the Magic Association early to read a book, and chatted with Jasmine for a while, invited her to afternoon tea, and brought lunch and dinner for Teacher Britney in the middle, and now the small cake is already supper.

Calvin scratched at his hair, and the thought of a dozen divine graces made his head almost explode.

He thought he would be able to solve these three problems quickly, but the truth is that whenever he thought he had found a way, he soon found that his method was wrong.

This feeling that he was almost touching the truth, but when he made up that little bit, he found that he was getting farther and farther away from the truth, was enough to make people crazy.

At this moment, he deeply realized the horror of the devil Blair.

He will give you hope, but when you keep moving along the path of what you thought you were hoping for, you will find that the end of this hope is actually the abyss of despair......
