I made science magic

Harrov and Linn pulled the string straight together, pressing one end under the icicle and the other end overlapping the shadow.

When the magic clock reached twelve o'clock, Harrov used his hand as a knife and cut off the remaining rope with great precision!

"Scale, bring the scale quickly!" Harrov shouted excitedly. Because he was in such a hurry when he came down, he even forgot to bring the most important ruler.

Alok, who had quick eyes and quick hands, immediately ran back to the airship and handed the scale to Harrov within ten seconds.

The legendary wizard solemnly took the scale and began to measure it in sections as if on a pilgrimage.

"Lord Harrov, what is the length of the shadow?" Several wizards accompanying him asked with great anticipation.

Harrov did not answer immediately, but measured it several times before speaking in a cautious voice. "It is one thousand and fifty-one centimeters, which is 10.51 meters!"

Everyone who got the data immediately took out paper and pen to calculate it. Although the great wizards who were qualified to take an airship to watch the experiment in person had not systematically studied Olympiad, they still knew the calculation methods of basic geometry.

However, this value is not a positive integer. In the case of decimals, the amount of calculation doubled after the square and then the square root. It took more than five minutes for everyone to use the Pythagorean theorem to calculate the approximate length of the hypotenuse.

Equal to 100.55 meters.

After more than two months of Mathematical Olympiad training, Lydia and Alok are obviously faster than them. They have already begun to calculate the angle of the vertex. Substituting it into the triangle formula, sine sin is equal to the ratio of the opposite side to the hypotenuse...

"I figured it out, the vertex angle is six degrees!" Lydia, who was the first to figure it out, waved her arms vigorously and shouted loudly.

Harrov, who didn't have a pen and paper, got the answer at the same time just by relying on mental arithmetic - Lydia did not make a mistake, the vertex angle of the triangle and the corresponding angle between the center of the earth and the earth's center were exactly six degrees!

The rest is easy to handle. A circle has 360 degrees. The angle between the center of the earth is equivalent to dividing the entire circle into 60 equal parts. Each equal part is 720 kilometers, so the total length is...

"Forty-three thousand two hundred kilometers!" Harrov's voice was trembling. He counted several times in his mind for fear of omissions. After confirming that it was accurate, he said as if he was dreaming. "Forty-three thousand."

Two hundred kilometers! This is the circumference of the planet beneath our feet!"

Lin En was naturally the fastest at calculating. After Zhinao obtained the data on the length of the shadow, he directly presented the answer in his mind.

It seems that this alien planet is slightly larger than the Earth in the previous life.

If he remembered correctly, the circumference of the earth should be 40,75 kilometers, and the two figures were very close.

The other wizards quickly calculated this value, and they were all so excited that they could not contain themselves. Once the circumference was known, it was only a matter of time to calculate the diameter, radius, and area.

Roll on the side did not participate in the calculation, but once again created a new picture called [People measuring the circumference of the planet under the scorching sun and ice]!

The quill stained with ink waved rapidly on the parchment.

Harrov, who was measuring the rope with a scale, Linn, who was staring at the sky as if estimating the angle between the center of the earth, Lydia, who was leaping high, and the wizards who were immersed in thinking behind them all appeared on paper, under the scorching sun.

It is extremely impactful against the backdrop of floating icebergs, forming a strange yet harmonious picture.

After all his inspiration was exhausted, Luo Er looked at the two scrolls in his hands and felt that he had no regrets in this life!

Because he knew extremely well that these two scrolls would definitely be remembered by the world forever along with this historic moment!

However, after sorting out his emotions, Luo Er did not forget another important matter, otherwise some people would not be able to wait.

Thinking of this, Rohr looked at Harrov and asked. "Master Harrov, do you want to send this news to Greenriel now?"

Harrov, who was calculating the surface area of ​​the planet, had no time to pay attention and just nodded casually. "Now that it's confirmed, let's send it!"

…

At the same time, in Greenriel City, a dozen alchemists were standing in front of the communication alchemy formation, anxiously waiting for the message from the other side.

But it was already twelve thirty-seven, and there was still no news, which made Raphael and others have to start to wonder if this operation had failed.

Is it possible that Linn's assumption is actually wrong and that this continent is not a sphere?

"Look, there's something moving!" A sharp-eyed alchemist immediately noticed that the formation was lighting up, and everyone immediately moved forward.

Since the distance was more than 700 kilometers, the amount of magic stones required to transmit information was also a terrifying number, so Rohr only transmitted the two most important data, shadow length and vertex angle.

"The length of the shadow is 10.51 meters, and the vertex angle is 6 degrees..." Raphael shouted excitedly as he looked at the data consisting of magic power that was constantly beating in the alchemy circle.

Under the influence of amplification magic, the news quickly spread throughout Greenriel City, and a strange scene appeared in the entire wizard city. Countless wizards who were looking forward to it took out parchment and

The quill began to count, and even many well-educated civilians participated.

If you only have the length of the shadow, you must be proficient in trigonometric functions to calculate the data, which is enough to stump most wizards.

But once you know the data of the vertex corners, it becomes the most basic multiplication and division, even some civilians can calculate it!

"The circumference of the planet is 43,200 kilometers, the diameter is about 17,51 kilometers, and the surface area is 594 million square kilometers?" On the crowded streets of Greenriel City, Ya

Li looked at the data he had just calculated and murmured to himself.

He is not a wizard, or due to his limited talent, he does not even have the opportunity to enter a certain magic school as a wizard apprentice, but he has a very strong interest in mathematics.

In the past, Alex thought that calculations could only be used in daily transactions, which meant that he became a tax officer, but the last issue of [Magic Daily] opened the door to a new world for him!

The wizard named Linn who came from the sea of ​​mist actually planned to measure the circumference of the planet under their feet, and he didn't need any magic, just a few simple mathematical formulas!

Alex originally didn't believe it would be so easy, but when these values ​​​​really appeared on the paper, he had no doubts in his heart. The shock was hard to calm down, and the world seemed to be under his pen!
