"Alok, it shouldn't be difficult for you to calculate the data of the planet under your feet now, right?" Lin En looked at the wizard apprentices and asked with a smile.
Alok and others nodded with great excitement. Only then did they realize that what the professor said when he gave the first class was not bragging. It is true that everything can be calculated in the Mathematical Olympiad!
Once you know the circumference of the planet, it is easy to calculate the radius, area and even volume.
The wizards in the seminar could not restrain their excitement. There are only ten days left until mid-July...
In other words, in ten days, the continent under their feet... no, it should be said that the entire planet will be displayed in front of them.
"I really don't know how your head is so long that you can think of such a strange method!" Raphael said with emotion.
Before Linn arrived, although there was no systematic Olympian mathematics in the land of wizards, most wizards still knew the calculation methods of basic geometric figures, but they never thought that they could calculate using such simple calculation methods. The circumference of the planet beneath your feet.
I'm afraid this is genius...
Facing the praises of everyone, Linn acted very calmly. After all, this method was not thought up by himself. It was the idea of the former [Father of Geography] Eratosthenes, and it was only based on the land of wizards. Things have changed a bit.
When searching for historical information in his previous life, Lin En was also surprised by the other party's genius thinking. This was simply using basic methods to solve the most complex problems!
"Are there any requirements for where to place this pillar?" Harrov couldn't wait to verify this conjecture. If it weren't for the fact that there were still ten days until mid-July, he would have wanted to take action now.
"The ground should be as flat as possible, and it must be at least 500 kilometers away from Greenriel. In order to make the data more accurate, it is best to be more than 1,000 kilometers away!" Linn said thoughtfully. "After all, the continent under our feet is too big. One scale may be tens or hundreds of kilometers. It is better to be as far away as possible. The pillars must be as high as possible so that the shadows are obvious enough."
So far away... Harov's brows couldn't help but frown.
As a result, it may be impossible to verify it in the wizard's land.
"There is a place that is very suitable. I heard that there is a tower hundreds of meters high outside the fog. This is a ready-made pillar." August suddenly suggested.
The wizards present were a little surprised, guessing what August was talking about.
Phillip on the side suddenly seemed to have thought of something, and suddenly said in shock. "Master August, are you talking about the Sky Tower in the Holy City?"
Although he had never reached the Sekas Empire, he had heard from Heran Ram and the sailors who traveled back and forth between the two places about some novel deeds outside the mist, including the Sky Tower.
It is rumored that it is the place where the creator of life, the Lord of the Stars, and the Goddess of the Moon [Ella] manifested, and it is the holy place in the hearts of all believers.
Philip naturally sneered at this so-called god, but he also knew the power the Holy See had. If they went to the Holy City to measure the shadow length of the Sky Tower, it would no longer be described as death. If you can't get through the gate, you will be caught and burned to death.
However, there are not many people as sensible as Philip, and many young wizards are even clamoring to go directly to the Holy City.
In their view, today's wizarding land is no longer the refuge of the exiled wizards.
After hundreds of years of development, they have created countless novel magics and established a wizard promotion system and a magic theory system, which are more powerful than imagined!
The picture of stars that Lin En told them made the wizards realize that the world is so big, but they are trapped in this small wizarding land...
But Harrov quickly poured cold water on him. "We only have ten days. Even if we set out now, we may not be able to reach the Sky Tower at the fastest speed."
"And there is no need to make it so troublesome. We can directly use magic to create a floating island on the sea and erect an icicle on it. The calculated data will be the most accurate!"
The side of the Wizarding Land facing the Sekas Empire is the Sea of Mist, but this does not mean that the entire island is wrapped in mist. In fact, the sea behind it is passable.
It's just that this sea is too wide. A great wizard once wanted to see what was on the other side of the sea. After flying for a month, he only found some uninhabited islands and ferocious sea beasts, and he almost couldn't find his way back. .
Under Harov's approval, public opinion did not evolve to the point of charging into the Sekas Empire and overthrowing the Holy See.
Although Harrov's floating island plan seemed to some wizards to be afraid of the "cowardly" approach of the Holy See, they did not dare to speak out against it. The focus of the discussion soon turned to how to determine the corona tower and pillars. distance.
A witch quickly suggested that they could find a very long rope, measure the length, and use it as a length unit, and then leave a trace on the ground as a mark for each distance of the rope. In the end, as long as Just count how many markers there are.
But this proposal was rejected soon because it was too troublesome, not to mention that the terrain of the Wizarding Land was undulating and there would be large errors.
After a heated discussion, the more convenient methods of distance measurement by horse-drawn carriage and ship quickly gained the upper hand.
"How about using an airship?" Lydia raised her hands high and suggested.
Raphael and others suddenly felt their eyes light up. He had just wanted to say this, but Lydia mentioned it first.
Compared with the alchemy ship that will be disturbed by wind and waves, the airship suspended in the air is undoubtedly a better choice.
Not only can it overcome all obstacles and achieve a true straight line, but after being blessed with windproof magic, the sailing speed is also very stable and not prone to fluctuations.
If sailing at full speed, the airship can sail fifteen kilometers per hour, so sailing at full speed in one day is 360 kilometers. It is still very accurate to judge the distance based on this...
Lin En did not participate in the discussion. He turned to look at the wizards of the prophecy school and asked with a smile. "Mr. Yolande, do you have any questions now?"
Yolande didn't reply in a daze, and his mind was filled with Lin En's method of measuring the circumference of a circle by dividing it into equal parts.
Although the accurate result has not yet been obtained, he understands that the prophecy school has lost this time, and it has lost completely!
