Chapter 144 Lynn: My apprentice can calculate the circumference of the planet with his feet
Seeing that Lynn was 'speechless' under Harov's inquiry, he could only excuse himself by saying he didn't know.
The originally ashen-faced wizards of the School of Prophecy suddenly backed up, and Yolande questioned as if he had found a breakthrough.
"Mr. Lynn, if I'm not mistaken, you shouldn't be a great wizard, so you can't use force field magic?"
Yolande's problem was very fatal, and many wizards who supported Lynn immediately discovered a serious problem.
Since the other party is not a great wizard and does not even know force field magic, how did he find out this gravitational formula.
"The formula of universal gravitation is calculated by me based on the three laws of star motion proposed by the legendary wizard Kepler, and then calculated using the Olympiad." Lynn replied with a calm expression, and repeated the three laws.
Last night, he used this method to confirm that the law of universal gravitation still applies in this different world, so he was very calm in the face of Yolande's inquiry.
"Calculation? How to calculate?" Another witch from the School of Prophecy jumped out immediately. "According to what you said, if you want to calculate the universal gravitation, you need to know the so-called gravitational constant, the distance between two stars, and their mass."
"A star is incomparably huge, tens of millions of times larger than Mount Kegal, the largest in the wizarding land, and the distance between them is so far away that it is unimaginable. How to measure this? Is it possible to use a ruler to measure it? Or is it impossible to weigh the continent under our feet on the beam?"
"If this is the case, then what should be placed on the other side of the scale, is it another star?" The witch said with a sneer.
In the hall of the discussion venue, thousands of wizards had a heated discussion.
Because the picture of the movement of the stars that Lynn showed them was too perfect, many people are still willing to believe that the gravitational formula proposed by Lynn is true.
But no matter how hard they think, they can't think of any way to calculate the weight and distance of these stars.
Raphael looked at Lynn and couldn't help but sighed. He suspected that this formula of universal gravitation might be a pure theory that had not been verified.
Originally, this is nothing, after all, there are many pure theoretical theories, and this one is not bad, but it has attracted the attention of Lord Harov, even to the point of awarding the Corona Medal.
If this theory turns out to be wrong in the end, no matter how much praise Lynn received before, the fall will be so tragic.
Yolande and the others breathed a sigh of relief. They had reason to believe that the other party's so-called universal gravitational formula was simply fabricated!
Lin En looked at the few people with pity in his eyes, as if he was looking at a fool...
"Don't think this process is too difficult, ladies and gentlemen, as long as you use some basic knowledge of the Olympiad, even a few of my apprentices can calculate the mass of a star and the distance between them."
Lynn spoke in a calm tone, but in the eyes of all the wizards of the school of prophecy, this is just nonsense. If Lynn can figure it out by himself, they may still believe it for a while, but if they say Even an apprentice wizard can calculate the data of the stars, so it can only be described as outrageous.
The eyes of thousands of wizards immediately turned to Johnny, Lydia, Elock and Pierce...
I'm not, I haven't, I can't figure it out!
Ellok is about to cry now. He has long discovered that Professor Lynn may have been holding some unrealistic illusions about their abilities.
Actually, they are not so awesome!
Such huge stars, how heavy they are, and how far they are from each other, how can I calculate it myself!
Lin En continued to speak as if he didn't see the resentful eyes of Ai Luoke and others. "If you want to measure the distance between the stars, you need to find a reference object in the vast universe, and the best reference object is the planet under our feet! As long as you know its data, everything will become easier! "
Yolande sneered, he wanted to see how the other party calculated the various data of the continent under his feet.
Lin En looked at Ai Luoke and the others, and asked suddenly. "If I want to know the circumference of a circle, what should I do?"
"You can multiply diameter by pi, professor!" Lydia shouted loudly, which she still remembers clearly.
"What if you don't know the diameter data?" Lynn asked again.
Lydia's small face immediately froze, and Ai Luoke and Pierce thought hard for a while, and finally Jonny pointed to the sand table on the high platform and responded.
"A circle has three hundred and sixty scales, and each scale is equal, so I can also judge its circumference by measuring the length of each scale line segment!"
"Very well said, Johnny, you have always learned the Mathematical Olympiad very well." Lynn laughed, and then continued. "The planet under our feet happens to be a circle, so it can be calculated using the same method?"
As soon as this remark came out, the wizards in the hall couldn't help but froze for a moment, as if it was the same thing.
"The planet under our feet is extremely huge, so how should we judge the angle and distance?" Harov frowned. He had flown to an altitude of tens of thousands of meters, and with the help of magic sight, he could see a slight The radian cannot be artificially divided into equal scales like the sand table under your feet.
Lin En didn't answer directly, but walked to the sand table and asked. "I heard that every year in mid-July, under the sunlight at noon, the shadow of the Corona Tower will overlap with the tower body. Is this true?"
"Not bad!" Raphael on the side nodded.
"Then I believe you have not forgotten that when I introduced the changes of the four seasons, I said that the point where the sun is directly on the sun, the reason why the tower of the corona has no shadow is precisely because at noon in mid-July, we are in the direct sun. Point!"
"We will use it as the zero scale!" Lynn walked to the sand table, took a wooden stick, and placed it on the place representing the zero scale in the sand table, and then put down the second stick a little farther away. stick.
"Then we only need to use magic to erect a towering column as far as possible from the Corona Tower, measure the length of the column and the shadow, and then we can calculate the angle between the center of the earth?"
"Take the towering pillar as the base point, and use the sunlight as a ruler...Genius, what a genius idea!" Harov said excitedly. In this way, the pillar is like a straight line on an arc, and the shadow is the other side of the right angle. This is a simple problem of finding the vertex angle of a right triangle!
Raphael and the others looked at the two wooden roots placed on the sand table, and couldn't help but gasped. How could this be possible?
