Greetings, Mister Principal: Perpetual motion machine

To a certain extent, perpetual motion machines have been a long-cherished wish of mages for many years, but just as even the most powerful legendary mages will eventually fall, there is no machine or magic in the world that can operate without external energy. continuous operation.

"Perpetual motion machine..."

This is a typical civil science routine, Reiner thought.

"Can we go take a look?"

He asked, Reiner had never seen how perpetual motion machines were designed in this world, and wondered whether it would be any different in the face of the power of magic.

"It should be ok, I see the conference room is not closed."

Igor was already sitting on the chair, his eyes fell on a paper on the table, and he seemed to lack interest.

"Then let me go and take a look."

Reiner didn't force Igor to pull him over, he walked out of the office alone and walked into the conference room next door.

As soon as he walked in, Reiner saw Director Percival and Roger. The two were sitting on the sofa, each holding a paper in their hands. Opposite them, a young man was in high spirits. He looked at the two people quietly, and he didn't notice until Reiner came closer.

"Hey, this is it?"

The young man wore an elegant dress robe, and the cuffs were embroidered with a gold edge in accordance with the regulations of the association to indicate his identity as a first-level mage.

He looked at Reiner up and down, noticed the identity of Reiner, and subconsciously thought that he was a mage responsible for doing odd jobs.

"Liner, why are you here..."

Director Percival raised his head, glanced at Reiner, and then felt helpless.

"Forget it, just sit aside and watch carefully."

He pointed to a row of chairs against the wall of the conference room. Since Reiner was here, it was not convenient to drive him away. Percival only hoped that Reiner would not cause trouble.

"My father often talks about you, Lord Orson. He said that you are a promising mage and you may even be promoted to a high level in the future."

The young man did not notice the whispers of Percival and Reiner. He said quietly while the two review committee members were reviewing the paper.

"Thank you, Mr. Dulavin, I was just doing my job faithfully."

Percival replied, he put down the paper, it seemed that he already knew what he was talking about.

"How about the 'Eternal Pendulum' I designed? Isn't it very innovative? It uses such a simple method to solve a problem that has troubled mages for thousands of years. To be honest, I didn't expect that I was so smart. ."

The young man asked again, his words revealing an indescribable arrogance.

"Haha, I think someone like Reiner Ingle would never come up with such a brilliant idea. I wonder if he, who is known as the most promising high-level mage in the past fifty years, would see me Will the paper cause cognitive collapse and explode on the spot?"

He speaks freely. It is obvious that his unknown father may not have taught him to keep a low profile.

Hearing what Mr. Duravin said, Percival smiled helplessly and did not explain more, but waited for Roger beside him to complete the review.

About five minutes later, Roger, wearing a single-sided glasses, put down his paper.

"Roger, please tell me your opinion first."

In Dulavin's expectant eyes, Percival asked Roger to make the first judgment.

Roger picked up the paper again, glanced at it, and continued.

"The design here, well, is indeed somewhat innovative, there are almost no examples in the past..."

"Right, let me just say, this is a unique design, you are witnessing history!"

Duravin said impatiently, his voice full of excitement.

"Uh, but..."

Roger paused, glanced at Percival, and then continued.

“But I don’t think this design can achieve the ability to continue operating permanently without any external energy supply. This is not a perpetual motion machine.”

Roger's words made Dulavin's eyes widen with an expression of disbelief.

He was stunned for a long time before he spoke, with a gloomy expression.

"Sir, I suggest you re-read my paper. I believe you will have different opinions."

"Actually."

Director Percival spoke at this time.

“I also feel that the design here is very flawed, and it is far from being permanent motion.”

The attitude of these two people surprised Reiner. He thought that according to Igor, these people were just messing around, and maybe Director Percival would get involved because of the power of Dulavin's father. They passed each other's papers against their will, but they didn't expect that the two of them still maintained the basic qualities of mages seeking truth from facts.

"You can't understand the mystery of this!"

Duravin's originally polite image immediately collapsed. He knocked on the table and argued rather dissatisfiedly.

"Come and see."

Director Percival suddenly turned around and handed Duravin's paper to Reiner.

"Uh, okay."

Reiner didn't know which part of the song he was singing. Even in the morning, Director Percival told him to do his job well and not to meddle in other people's business.

He took the paper and soon saw the design drawing of the so-called perpetual motion machine.

It is a roulette wheel with twelve sticks of equal lengths evenly mounted on it. One end of the stick is a small ball. When the roulette wheel rotates, the small **** on one side will move away due to centripetal force. The other side will be close to the axis, so that it seems that it can keep running forever relying on the conversion of centripetal force and inertia.

"How can a first-level mage understand the subtleties of my design? Mr. Percival, listen to me..."

"Of course this cannot be a perpetual motion machine."

Leiner interrupted the other party and continued before Dulavin could refute.

"This seems to be able to run continuously, but in fact, the number of small **** located on the left and right sides of the rotating axis are not the same. If a mathematical model is established, these equations can be obtained..."

He quickly started writing on the blackboard in the conference room~IndoMTL.com~ and established a series of equations. Through substitution and elimination, the equations on both sides finally got the same answer.

"In other words, when this condition is reached, the entire machine will stop running due to force balance. This proves that this design is not a perpetual motion machine. This is a simple mathematical calculation that requires no more than two levels of mathematics. Huan, I don’t know why Mr. Duravin didn’t do the math for himself first.”

Reiner put down the chalk. He saw Director Percival's eyes widen slightly. This series of calculations was obviously beyond his expectation.

On the other side, Duravin's face was red. Obviously, Reiner's use of mathematical means to completely deny his thesis made Duravin feel extremely humiliated. His hands were shaking slightly, and he was about to To break out.

"Who are you to question me like this?"

He asked in a deep voice, gritting his teeth.

"Linard Ingle, if I remember correctly, are you still planning to blow my head off?"

Putting down the chalk, Reiner patted the chalk dust on his hands.
