I Made Scientific Magic

  Chapter 161 Mathematical Olympiad is the foundation of everything

In order to ensure that the calculated gravitational constant is accurate enough, Lynn asked the great wizards to create a vacuum field again, and asked Jonny and others to withdraw from the high platform to minimize the interference. After several experiments, the gravitational constant The final value was soon 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 power, 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 oneself. Another important data, the acceleration of gravity, has also been calculated by Lynn, which is about 10m/s^2, which is slightly higher than that of the earth. The value of 9.8.

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

  The acceleration due to gravity is multiplied by the square of the radius and then divided by the gravitational constant.

  After Lynn roughly described the derivation process of the formula, Harov and others immediately took out a pen and paper to calculate.

  The square of the value of the huge planet, divided by the extremely small gravitational constant, makes the scalp tingle...

   "I can't figure it out, I can't figure it out...it's too difficult!" Looking at the numerical values ​​piled up on a whole page of parchment, Luo Er felt dizzy for a while.

  Beside Raphael was desperately pulling his few hairs, fine beads of sweat had already appeared on his forehead, just to figure out the final result.

   Even though there are thousands of obstacles, few people choose to give up. After all, the last mystery of the planet under their feet is in front of them. They have reached the gate of truth, and they can kick it away with just one kick.

  The only problem is that the door is too hard, and it is easy to break yourself...

   A full hour and a half later, a wizard stood up excitedly, almost insane, and shouted loudly. "I figured it out, it's sixty-seven trillion tons!"

   After finishing speaking, he stared straight at Lynn, hoping to get the other party's affirmation.

  However, Lynn just shook his head. Harov, who had just calculated the data, was going to be much more straightforward, and directly vetoed it. "It's wrong, it's outrageous!"

"Wrong, how could it be wrong?" The excited expression on the wizard's face immediately froze, he grabbed several parchment scrolls in front of him, and after careful review several times, he realized that he was writing the value of the radius of the planet. I mistyped a number at the time, and the unit used is still kilometers.

  That is to say, he needs to add N more zeros and do the calculation again... His one and a half hours are all for nothing!

   Realizing this, the wizard trembled and spat out a mouthful of blood, and passed out on the spot.

   Eloque gave him a sympathetic look, and then stopped writing, even official wizards are so difficult, it is better for apprentices like them to wait for the answer directly.

Although the calculation of huge numbers is difficult, as time goes by, more and more people have calculated the result. It is a number that cannot be accurately described by any existing unit. Only by using the formula of the Olympiad can it be intuitively show out.

  7.08×10^24kg!

   "No wonder, in the [Secret Society], the mysteries are the foundation of everything..." Harov finally understood.

   Numerical values ​​such as gravity and stars that are either extremely huge or as small as dust can only be clearly calculated through the derivation of the Austrian number.

  Thinking of this, Harov announced the result directly. After getting the confirmation from Lynn, he secretly heaved a sigh of relief. With such a huge value, even after repeated confirmations, he was worried that there would be mistakes and omissions.

   Koror and the others looked at Ogst with weird eyes. They remembered the weight of the planet estimated by the star of magic? It seems to be 30 trillion billion tons...

   Isn’t that a little too much difference?

  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 Lynn's gravitational substitution formula that directly points to the essence of weight...

   Facing the mocking gazes of Koror and others, Oghst remained calm. The 20% deviation he said actually meant zero...

  …

  The discussion about the gravitational constant and the weight of the planet continued until night. Some fanatical wizards of the prophetic school estimated the mass of other planets in the star system based on the law of universal gravitation, and planned to reconstruct a picture of the movement of stars.

The witches in the venue were more interested in the round mirror that Lynn took out during the experiment. After learning that this smooth and flawless glass mirror could be mass-produced and only sold for 20 magic gold coins, they were overjoyed. win.

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

   In order for these wizards to understand certain terms, he has had a hard time. After all, there are 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 intrinsic mass multiplied by acceleration, and then you must first explain what mass is. what…

Fortunately, after such a toss, the effect far exceeded his expectations. The Secret Law Society, the Olympiad, and the Iyeta School are so famous in the wizarding land that some solo wizards began to test his tone, asking if he could Join the Iyeta School.

   "As for your nomination for the Corona Medal, it has been approved by the Parliament. The award ceremony will be held in two days. You'd better take some time to prepare." Harov said with a smile.

   "Are there any rules or points that need to be paid attention to?" Lynn asked, thinking that he just went up to receive an award.

"That's not true, but this is the first time that the highest award in magic science has been awarded to an official wizard. You have to say a few more words to convince the public." Harov said jokingly, and then straightened his face. Then he said. "I think there are still some omissions in Ni's theory of universal gravity."

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

   "What can affect time and space is not only quality, but also magic power!"

  Lin En couldn't 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!

   It's just not the time to come up with the mass-energy equation.

  As for the law of universal gravitation, Harov will always be able to deduce it in a few years even if he doesn’t have himself. The difference is just an inspiration...

(PS: I have indeed written a lot in terms of scientific research these days. I just wanted to write down the derivation of universal gravitation. In the end, there are too many things to explain and pre-tests. One by one, the calculation of the data is mentally declining... Fortunately, I have finished writing, please forgive me.)
