I Created Scientific Magic-Chapter 155 - 142 Lynn: My Apprentice Can Calculate the Circumference of a Planet with Their Feet (Please Subscribe)

Seeing Lynn was rendered speechless by Harrov’s inquiry, he could only excuse himself by claiming ignorance.

The previously ashen-faced wizards of the Prophecy School perked up all at once, and Yoland seemed to have found a breakthrough, interrogating him.

"Mr. Lynn, if I’m not mistaken, you are not yet a Grand Wizard and thus unable to use force field magic, correct?"

Yoland’s question was quite lethal, and it immediately made many wizards who supported Lynn realize a severe issue.

Since he was not a Grand Wizard and did not know force field magic, how then could he have explored this gravity formula?

"The universal gravity formula is based on the legendary Wizard Kepler’s three laws of celestial motion, which I calculated using arcane arithmetic," Lynn replied with composure, and he recited the three laws once more.

He had confirmed the night before with this method that the universal law of gravitation still applied in this other world, so he faced Yoland’s inquiry with great calm.

"Calculated? How did you calculate?" Another witch from the Prophecy School immediately jumped out. "According to your statement, to calculate universal gravitation, one must know the so-called gravitational constant, the distance between two celestial bodies, and their mass."

"A celestial body is unimaginably vast, thousands of millions of times larger than the largest mountain in Wizard Land, Mount Kogal, and the distance between them is remotely beyond imagination. How could one measure such distances, perhaps with a ruler? Or should we weigh the continent beneath our feet on a scale?"

"If that’s the case, what should we place on the other side of the scale, perhaps another celestial body?" the witch said mockingly.

Within the debating hall, over a thousand wizards engaged in heated discussions.

Because the celestial movements demonstrated by Lynn were so perfect before, many were still willing to believe that the gravity formula proposed by Lynn was real.

But no matter how hard they pondered and meditated, none could think of a way to calculate the mass and distance of these celestial bodies.

Rafael sighed at Lynn, suspecting that this universal law of gravitation might be an unverified pure theoretical proposition.

That would normally not be an issue, as there were many purely theoretical propositions, and one more wouldn’t make a difference. But it had attracted the attention of Lord Harrov to the point where he was considering awarding the Corona Medal.

If this theory was ultimately proven incorrect, the more acclaim Lynn had received previously, the more catastrophic his fall would be.

Yoland and the others breathed a sigh of relief, for they had reason to believe that this so-called universal law of gravitation was entirely fabricated!

Lynn looked at them with eyes full of pity, as if he were looking at a fool...

"Don’t make this process seem too difficult, ladies and gentlemen. With some basic fundamental arcane knowledge, even my apprentices can calculate the mass of a celestial body and the distance between them."

Lynn said in an even tone, but to the wizards of the Prophecy School, it sounded like mere boastfulness. If Lynn claimed he himself could calculate it, they might believe him a bit, but to suggest that even a wizard apprentice could work out celestial data was simply preposterous.

The gaze of a thousand wizards immediately shifted to Johnny, Lydia, Ailoke, and Pearce...

I’m not, I didn’t, I can’t calculate it!

Ailoke felt like crying at that moment; he had long realized that Professor Lynn might have always harbored some unrealistic expectations for their abilities.

Truthfully, they were not that amazing!

How could he possibly calculate the weight and distance of such massive celestial bodies!

Lynn, as if blind to the resentful looks from Ailoke and the others, continued, "To measure the distance between stars, we first need to find a reference point in the vast cosmos, and the best reference point is our planet beneath our feet! Knowing its data, everything else becomes manageable!"

Yoland scoffed, eager to see how Lynn planned to calculate the data for the land beneath them.

Lynn turned to Ailoke and his group and suddenly asked, "If I want to know the circumference of a circle, what method should I use?"

"You could multiply the diameter by pi, Professor!" Lydia called out loudly, remembering it quite clearly.

"What if you don’t know the diameter?" Lynn asked further.

Lydia’s face immediately froze, while Ailoke and Pearce racked their brains for a while until Johnny gestured towards the sand table on the high platform and responded.

"A circle has three hundred and sixty degrees, with each degree equal. Thus, I could also determine its circumference by measuring the length of each degree segment!"

"Well said, Johnny. Your arcane mathematics have always been excellent," Lynn said with a smile, then continued, "The planet beneath our feet happens to be a circle, too. Couldn’t we use the same method to figure it out?"

At these words, the wizards in the hall involuntarily paused, as if that made sense.

"This planet beneath our feet is incredibly vast; how can we determine angles and distances?" Harrov frowned; he had flown tens of thousands of meters high, and only with the help of magic vision could he see a slight curvature. It was impossible to divide it into equal degrees as with the sand table.

Lynn did not answer directly but walked up to the sand table and asked, "I have heard that every year around mid-July, at noon, the shadow of Corona Tower coincides with the tower itself because of the sunlight. Is that so?"

"Indeed!" Rafael nodded on the side.

"Then I trust you have not forgotten, when I introduced the changes of the seasons earlier, I mentioned the direct solar point. The reason why Corona Tower has no shadow is that at noon in mid-July, we are right at the Sun’s direct solar point!"

"Let’s use that as the zero degree!" Lynn approached the sand table, took a stick, and placed it at the location representing zero degree, followed by a second stick a little further away.

"Then, we just need to place a towering column as far from Corona Tower as possible, and by measuring both the column and its shadow, we can calculate the angle to the core of the Earth, can’t we?"

"With the towering column as the base, using sunlight as a ruler... Genius, a truly genius idea!" Harrov exclaimed excitedly. The column would thus be akin to the straight line on the arc, and the shadow the other side of the right angle – a simple right-angled triangle problem for determining the angle of the vertex!

Rafael and others looked at the two sticks on the sand table and drew in a sharp breath, amazed at the notion.
