In order to ensure that the calculated gravitational constant was accurate enough, Lynn had the Grand Wizards create a vacuum domain again, and had Johnny and others retreat from the high platform to minimize disturbances. After several experints, the final value of the gravitational constant quickly appeared before everyone.
6.67×10^-11N·m^2/kg^2
This was consistent with the universe of his previous life. It seed that besides possessing the special energy known as magic power, the basic paraters of the two universes were roughly the sa.
However, the symbol representing gravity, N, would probably need to be replaced with his own L, and another important data, the acceleration due to gravity, had already been calculated by Lynn to be about 10m/s^2, slightly higher than Earth’s value of 9.8.
With these two values, calculating the weight of the planet beneath their feet beca extrely easy, requiring only the use of the universal gravitational formula derived from the gold exchange formula GM=gR^2.
That is, the acceleration due to gravity multiplied by the square of the radius divided by the gravitational constant.
After Lynn briefly explained the derivation of the formula, Harrov and others imdiately took out paper and pen to start calculating.
The huge planetary value squared, divided by the minuscule gravitational constant, made the calculators’ heads numb with complexity...
"I can’t figure it out, I can’t figure it out… This is too difficult!" Luo’er, looking at a whole page of amassed values on the parchnt, only felt dizzy and blurred.
Rafael beside him was frantically pulling at his sparse hair, with fine beads of sweat already appearing on his forehead, all just to calculate that ultimate result.
Despite nurous obstacles, few chose to give up, as the final secret of the planet beneath their feet was right in front of them; they were on the verge of the door to truth, just one step away from kicking it open.
The only problem was that this door was too solid and could easily cause them to fracture themselves...
After an entire hour and a half, an excited male witch stood up, nearly mad, and shouted loudly, "I’ve got it, sixty-seven trillion tons!"
Having said that, he stared straight at Lynn, hoping to get his affirmation.
However, Lynn simply shook his head. Harrov, who had recently calculated the data, was much more direct in his rejection, "Wrong, terribly wrong!"
"Wrong, how could it be wrong?" The male witch’s excited expression imdiately froze. He grabbed several parchnts in front of him and reviewed them carefully a few tis before realizing that he had written one figure wrong for the planet’s radius, using kiloters as the unit.
That ant he needed to add several zeros and recalculate all over again… His hour and a half of work was all for nothing!
Realizing this, the male witch’s figure trembled as he spat out blood and fainted on the spot.
Ailoke looked at him pityingly, then stopped writing. Even formal witches were struggling so much with the calculations, so it would be better for apprentices like them to just wait for the answer.
Although the computation of huge numbers was difficult, as ti went by, more and more people figured out the result, which was a number that could not be accurately described using any existing units and could only be vividly portrayed using the arcane formula.
7.08×10^24kg!
"No wonder, in the Secret Magic Society, arcane mathematics is the foundation of everything…," Harrov finally understood.
With values as vast as gravity and stars, or as minute as dust, only through arcane derivation can they be clearly calculated.
At that thought, Harrov imdiately announced the result and after receiving Lynn’s confirmation, he also secretly breathed a sigh of relief. Such a huge value could still be a bit worriso even after repeated confirmation.
Korol and others looked at August with an odd gaze. They rembered, how much had the Magic Star estimated the weight of the planet to be? It seed to be 30 quintillion tons...
Isn’t that a bit off?
It seed that the so-called Magic Star was not all that remarkable after all. The thod of calculating soil weight, compared to Lynn’s direct pointing to the essence of weight through the Universal Law of Gravitation, was not even worth ntioning...
Facing the mocking gazes of Korol and others, August kept his composure. The 20% deviation he spoke of actually referred to the number of zeros...
...
The discussion about the gravitational constant and the weight of the planet continued into the night. So zealous wizards from the Prophecy School even started calculating the mass of other planets in the solar system using Newton’s law of universal gravitation, intending to reconstruct a picture of the stellar movents.
The female wizards present were more interested in the round mirror Lynn had used during his experint. Upon learning that these flawless glass mirrors could be mass-produced and sold for only twenty Gold Coins each, they were overjoyed.
It was not until the seminar ended that Lynn finally managed to escape from being constantly chased with questions.
In order to make these wizards understand so terms, he indeed had to beat his brains out, as the things he had to explain were simply too nurous.
The cultures, vocabularies, scientific levels, and even thought processes of the two worlds were different. For example, to use the universal gravitation formula to calculate the weight of a planet, he first had to tell the wizards that weight is essentially mass tis acceleration, and then he had to explain what mass actually is...
Fortunately, all this trouble exceeded his expectations. The Secret Magic Society, Mathematical Sorcery, and the Iyeta School beca quite renowned within Wizard Land, so much so that so solitary wizards started to probe his opinions, inquiring about the possibility of joining the Iyeta School.
"Regarding your Corona dal nomination, it has been approved by the council. The award ceremony will take place in a few days, so you had better make so ti to prepare," Harrov said with a smile.
"Are there any rules or anything I should be aware of?" Lynn inquired, thinking it was just a matter of going up and receiving an award.
"Not really, but this is still the first ti the highest award in Magic Academic is to be presented to a formal wizard. You’ll need to say a few more words to convince everyone," Harrov said jokingly, then straightened his face and continued. "I think there are still so gaps in your theory of universal gravitation."
Lynn’s expression also beca serious, but he soon listened to Harrov say solemnly.
"It’s not just mass that can influence spaceti, but also Magic Power!"
Lynn couldn’t help but laugh and cry at the sa ti. He thought Harrov was about to propose so novel theory.
Of course, he knew that point, after all, matter is energy, and energy is matter!
It just wasn’t the ti to bring out the Mass-Energy Equation yet.
As for the law of universal gravitation, even if he wasn’t there, Harrov would derive it himself within a few years. All that was missing was an inspiration...
(PS: Indeed, I have written quite a bit about scientific research these past few days. Initially, I intended just to write about the derivation of universal gravitation, but there was too much to explain and too many preliminary experints, one thing led to another, and calculation made ntally exhausted... Fortunately, I’ve completed it now, please excuse it.)
