I made science magic

Chapter 161 Mathematical Olympiad is the foundation of everything

In order to ensure that the measured gravitational constant was accurate enough, Linn once again asked the great wizards to create a vacuum field, and asked Jonny and others to retreat from the high platform to minimize interference terms. After several experiments, the gravitational constant was determined.

The final value was quickly presented to everyone.

6.67×10^-11N·m^2/kg^2

This is basically the same as the universe in the previous life. It seems that except for the special energy of magic, the basic parameters of the two universes are roughly the same.

However, N, which represents the symbol of gravity, probably needs to be replaced with L, which represents itself. Another important data, the acceleration of gravity, has been calculated by Lin En a long time ago. It is about 10m/s^2, which is slightly higher than that of the earth.

The value is 9.8.

With these two values, it is extremely easy to calculate the weight of the planet under your feet. You only need to use the golden substitution formula GM=gR^2 derived from the universal gravitation formula.

That is, the acceleration due to gravity multiplied by the square of the radius divided by the gravitational constant.

After Linn gave a rough description of the derivation process of the formula, Harrov and others immediately took out paper and pen to calculate.

The square of the huge planet's value, divided by the extremely small gravitational constant, makes people's scalp numb...

"I can't figure it out, I can't figure it out... This is too difficult!" Rohr looked at the values ​​piled up on a whole page of parchment and felt dizzy.

Next to him, Raphael was desperately pulling at his few hairs, and beads of sweat had appeared on his forehead, just to calculate the final result.

Even if there are all kinds of dangers, few people choose to give up. After all, the final secret of the planet is right in front of them. They have reached the door of truth, and they only need to kick it open.

The only problem is that the door is too hard and you can easily break it if you kick it...

Exactly an hour and a half later, a wizard stood up excitedly, almost crazy, and shouted loudly, "I calculated it, it's sixty-seven trillion tons!"

After finishing speaking, he stared directly at Lin En, hoping to get the other party's approval.

However, Linn just shook his head. Harrov, who had just calculated the data, was much more straightforward and vetoed it directly. "It's wrong, it's very wrong!"

"Wrong, how could it be wrong?" The excited expression on the wizard's face immediately froze. He grabbed several parchment rolls in front of him and carefully reviewed them several times before he realized that he was writing the planet's radius value.

I made a mistake when writing a number, and the unit was still kilometers.

In other words, he needs to add N zeros and do the calculation again... All his calculations for an hour and a half were in vain!

Realizing this, the wizard trembled, spit out a mouthful of blood, and fainted on the spot.

Elok glanced at him with pity, and then stopped writing. Even formal wizards found it so difficult, so apprentices like them would be better off just waiting for the answer.

Although the operation of huge numerical values ​​is difficult, as time goes by, more and more people have calculated the result. It is a number that cannot be accurately described with any existing units. Only by using the Olympian formula can it be intuitively

Show it.

7.08×10^24kg!

"No wonder, in the [Arcane Society], arcane mathematics is the basis of everything..." Harrov finally understood.

Numerical values ​​such as gravity and stars, which are either extremely huge or as small as dust, can only be clearly calculated through arcane mathematical derivation.

Thinking of this, Harrov directly announced the result. After receiving Lin En's confirmation, he secretly breathed a sigh of relief. Even with such a huge value, even after repeated confirmation, he was still worried that there would be errors.

Korol and others looked at August with strange eyes. They remembered how much the magic star estimated the weight of the planet? It seemed to be 30 trillion tons...

Isn’t this a bit much?

It seems that the so-called magic star is nothing more than that. The method of dividing and calculating the weight of soil is not worth mentioning at all compared to Linn's gravitation substitution formula that directly points to the essence of weight...

Facing the mocking looks of Korol and others, August remained calm. The 20% deviation he mentioned actually refers to the number of zeros...

…

Discussions about the gravitational constant and the weight of the planet continued into the evening. Some fanatical wizards of the prophecy school even estimated the masses of other planets in the star system based on the law of universal gravitation, intending to reconstruct a picture of the movement of the stars.

The witches in the venue were more interested in the round mirror that Lin En brought out during the experiment. After learning that this smooth and flawless glass mirror could be produced in batches and only sold for twenty magic gold coins, they were all overjoyed.

win.

It wasn't until the end of the seminar that Linn finally got rid of the situation of being chased and asked.

In order to make these wizards understand certain terms, he struggled a lot. After all, there were too many things to explain.

The culture, vocabulary, scientific level, and even human brain circuits of the two worlds are different. For example, if you use the formula of universal gravitation to calculate the weight of a planet, you must first tell these wizards that weight is the essential mass multiplied by acceleration, and then you must first explain what mass is.

What……

Fortunately, after all this hard work, the effect far exceeded his expectations. The Arcane Society, Mathematical Olympiad, and Iyeta School were so famous in the land of wizards that some lone wizards began to test his voice and asked if they could

Join the School of Ietta.

"As for your nomination for the Order of the Coronation, it has been approved by the parliament. The award ceremony will be held in two days. You'd better take the time to prepare." Harrov said with a smile.

"Are there any rules or anything I need to pay attention to?" Lin En asked. He thought he would just go up and receive an award.

"That's not true, but this is the first time that the highest academic award in magic has been awarded to an official wizard. You have to say a few more words to convince the crowd." Harrov said jokingly, then straightened his face,

Then he continued, "I think there are still some omissions in your theory of universal gravitation."

Lin En's expression also became serious, but soon he heard Harov speaking solemnly.

"It's not just mass that can affect time and space, but also magic!"

Linn didn't know whether to laugh or cry. He thought the other party was going to say something novel.

Of course he knows this, after all, matter is energy, and energy is matter!

But now is not the time to come up with the mass-energy equation.

As for the law of universal gravitation, even without himself, Harrov could always deduce it in a few years. The only difference was an inspiration...

(PS: I have indeed written a lot about scientific research these days. Originally I just wanted to write down the derivation of gravity, but it turned out that there were too many things to explain and pre-experiments, one after another, and even the data calculations made me mentally exhausted...

…Fortunately, I have finished writing it, please forgive me.)
