The Academy’s Health Teacher Wants to Take a Break

Episode 33. It is to explain it so that even an idiot can understand it.

“…… So let’s finish the ordinance with this and proceed with the class right away. Everyone, open your textbooks.”

After finishing his attendance, Professor Cronus opened the textbook he had brought and prepared to bring the chalk to the blackboard as usual.

To proceed with the scheduled morning class immediately.

The students of the excellent class also started taking out their textbooks and school supplies that they had prepared just in time.

Even if the progress is urgent, it has already been repeated for a month.

Professor Kronos, realizing that their preparations had been completed, took the chalk to the blackboard.

“Then, before starting this class, I would like to briefly review what I have learned so far.”

– Tak, Tak Tak!

“What you all learned in the past month was the basics needed to handle mana, which is the basis of magic. And mana is the energy that creates physical force in response to will……. In other words, the foundations needed to deal with it must naturally be based in physics.”

The moment you write down all the necessary information on the blackboard.

Soon, Cronus’ gaze turned to a place in the classroom.

“Camilo.”

“Oh yes!”

A boy stands up as soon as his name is called.

Professor Kronos asked him directly.

“Tell me step by step what you have learned so far right here. What are the three basics I need to learn to deal with mana?”

“Yes, the first is the law of conservation of energy.”

“Sylvia. Briefly explain what the law just referred to is.”

“Okay!”

The gaze is directed to the other side, terrifying to answer.

The girl immediately stood up and opened her mouth to speak.

“The Law of Conservation of Energy states that the total amount of energy produced by a particular phenomenon is constant.”

“What is it trying to explain?”

“Energy is the result of mass plus velocity… …. In other words, it is possible to convert mass into energy, and in this case, it means that only the properties change, but the values of each other are the same.”

“Yes, as the saying goes, all the phenomena we encounter are nothing but ‘transformation’ that derives something from something, rather than creating something out of nothing. And this is why magic is called not an omniscient skill.”

To an outsider, magic literally looks like a bizarre and mysterious technique.

However, there are principles for everything in this world, and all of them can be mathematically interpreted.

The basis, also called the law of conservation of energy or the law of conservation of mass in physics, is built on this premise.

“Go ahead, Camilo.”

“The second is the law of conservation of momentum.”

“Clara, please explain in a nutshell.”

“The logic is that all types of motion remain constant unless an external force is applied, and the sum of all forces generated during a collision is +-0.”

“Yes, this law also teaches us that all the phenomena we know are the result of countless forces and their collisions. Of course, the process of calculating it would never be left out of Magic Esha, which handles physical force itself. Camilo, say the third one last.”

“The third is the law of conservation of angular momentum.”

“This time, Camilo, let me answer you. What does angular momentum mean?”

“If the second law mentioned above deals with a force with a constant direction, that is, linear momentum, angular momentum deals with rotational motion that circulates around a point.”

“Well explained. Have everyone sit down.”

Students seated right away.

After Professor Cronus took his eyes off them, he reached out his hand and continued talking.

“Yes, rotation is a concept that must be understood when it comes to managing mana. The reason is that dealing with magic is, after all, based on the human body……. Even so, if you focus only on linear movements, that power will leave your body and dissipate.”

-Giying.

A ring of physical force created on his hand with a vibrating sound.

Commonly called the ‘circle’, it was one of the factors that proved the scale of a mana user’s realm.

“Creating a circle in this way is to attract more power to one place… When creating a large number of these circles, it induces a collision between enormous forces and makes it easy to attract external forces. It doesn’t And the magic that uses this circle is also based on the three things mentioned above… As the importance has been emphasized so far, I think you newbies will fully understand.”

Professor Cronus, who finished the outline, turned his back and started tapping the chalkboard again.

“Now, let’s finish the review with this and move on to the next one. We learned the advanced process of this law of conservation of energy among the three basics. And this law of conservation of energy shares its characteristics in many parts besides basic mechanics. That’s the concept you’re going to learn today.”

Sure. An underline drawn in any part.

The eyes of all the students were directed to the word at once.

‘Thermodynamics.’

It is literally a study that deals with work related to heat.

“What is heat? Shouldn’t heat also be defined as energy? Nevertheless, why is heat separated from basic mechanics?”

Cronos expresses the questions that come to mind the moment you read the article.

After that, he raised his hand on his desk and said firmly to the students, raising his glasses.

“That’s because heat is not just a concept that deals with the degree of hotness and coldness.”

He is serious about everything, and puts his weight into it.

That’s because what has been discussed now is as important as the three foundations mentioned above.

“Molecules of all objects are in endless motion even at this moment, and this in itself can be said to mean that heat exists in everything in this world. Of course, when it comes to magic that manipulates everything, heat is a concept that must be taken into account.”

The concept of heat exists.

The basic preparation for advanced magic that draws external force based on the creation of a circle is also inefficient or inevitably causes errors if this factor is not considered.

“The laws of thermodynamics are largely divided into three categories. Third of these……. In other words, the explanation of how the heat on absolute zero is applied will be skipped. Since, in fact, it is premised on the logic that all things contain heat, absolute zero is bound to be a theoretical concept.”

How can a concept that is hypothesized even in academia be taught to students who have just broken the basics?

So what we need to focus on is a more fundamental and solid concept than that. This will be the 1st and 2nd laws.

“First, the first law of thermodynamics. The total amount of energy present in an isolated system is always constant……. As explained earlier, this is a property shared with the law of conservation of energy, so let’s move on and explain the second law.”

After that, Professor Cronus drew a circle on one of the writings on the blackboard and said it as if showing off it.

“The second law of thermodynamics. ‘Entropy’ that exists in an isolated system never decreases.”

Unlike the other parts, this sentence is especially emphatic.

The reason is that people who want to understand this field make the most mistakes in the second law.

“… Has anyone done a preliminary study on this entropy?”

Before explaining it, Professor Cronus turned to the students and asked, just in case.

Originally, mechanics can only be learned in earnest if you enter the high school of the academy or a graduate school that is higher than that.

Excellent classes are recognized for their unique abilities and learned in advance, but of course, even if you have learned so far, it is not easy to prepare for the next course as the level of difficulty is high.

That’s why it’s usually just barely following the progress.

“Yes, there is one.”

However, there are always one or two who stand out among geniuses in every jockey.

That was the girl with red pigtails who just raised her hand.

“Bean Juggret.”

Professor Cronus asked the name while talking about it.

“Do you understand what entropy is, as discussed in this second law?”

“Yes.”

Beans stands up with a confident face.

Seeing her, Professor Cronus raised her glasses and said firmly.

“Then, let’s try to summarize it in an easy-to-understand manner.”

Because he believed that if he really understood it, he could achieve what he wanted.

“Entropy is a word that expresses the thermal state of matter, and is mainly used to describe the flow of energy that is not useful. Because of this, the energy of the isolated system has no choice but to increase at all times, and the formula for this is the value of dividing the size of thermal energy by the movement of heat… ….”

“Bean Juggret.”

But just listening to the preface was enough for that thread of hope to evaporate.

“What did I say at the beginning?”

Beans cringes at the hard gaze.

I am a proud and stubborn child, but I couldn’t help but feel intimidated by Professor Cronus’ gaze.

“…I was told to organize the second law of thermodynamics.”

“I told you to organize it in an easy-to-understand way.”

The two eyes of Cronus are becoming narrower.

“And you were given the role of presenting your knowledge in front of the ignorant children here. Do you think that explaining the contents of the textbook to those who do not know anything in such a circumstance is conveying the meaning?”

“That… ….”

“As I have emphasized several times, the process necessary for science is not memorization, but ‘understanding’. And true understanding is not only a concept alone, but only when you can share it with others.”

The logic that only one person understands is ultimately nothing more than the realm of fantasy.

Professor Cronos is a person who believes that understanding can only be established when it is shared, and that is why when he lectures, he has always aimed to induce students to answer.

That’s the same as the current question.

What he induces is understanding, not memorization.

“I say it again. Do you pride yourself on fully understanding the knowledge you have acquired and being able to explain it in an understandable way?”

“…… Sorry. My thoughts were short.”

Bean Jugret lowers his head without giving an answer.

Her face was full of displeasure, but Professor Cronus judged her mercilessly and ordered her to take her seat.

Then she thought.

The reason why she scored a very poor grade of 97 on her midterm exam was because, like now, there are limits to expression.

‘Essay writing is also an important quality in academia. That concept should be emphasized from an early age in the best children.’

It’s smart, but it won’t be easy for a 14-year-old boy or girl to perfectly fulfill that quality.

So normally I should end it at this point…….

“Dale Enburton.”

Just one person.

Unlike in the past, there was one child who even met that condition.

“You, like Beans, have been preparing, right?”

“… ….”

“Dale Enburton!!”

“Huh?!”

Dale Enverton, the boy who was concentrating on the blackboard, screamed and hurriedly stood up from his seat.

She shrugged her shoulders in amazement. The appearance that would make her teary-eyed if she stimulated her a little more was stimulating the guilt of the person she faced.

“…Hmm.”

Look at that figure for a very short time.

Professor Cronus, who lost his gaze for a moment, cleared the atmosphere by clearing his throat, then asked Dale quietly.

“…… Are you asleep?”

“Oh, no. Stop focusing too much…”

“It’s good to focus on the class, but focus on me rather than the blackboard.”

“Sorry, sorry… …. Right!?”

A boy biting his tongue because he was so flustered.

If such behavior were the result of not attending class, I would have considered expulsion, but the girl in front of me…

No, the boy had succeeded in getting top marks not only in the entrance exam but also in the midterm exam.

“… Originally, you should give an admonition, but if you answer the current question, let’s move on right away.”

So let’s give it a chance.

Unlike the second seat, he waits to see if he can come up with a satisfactory answer.

“Dale Enburton. Explain the entropy of the second law of thermodynamics as concisely as possible.”

“As much as possible, you mean?”

“Yes, I will try to explain it in a way that even an idiot can understand.”

Though his voice is sharp, Professor Cronus is speaking seriously.

From noble mtl dot com

Even if you are a genius, everyone is bound to be an idiot when it comes to a new field.

Then can the boy say what the second law of thermodynamics is trying to explain in a way that even such fools can understand?

“Mmm… ….”

To that question, Dale put his chin on his chin and answered after pondering.

“Leftovers, leftovers.”

“… ….”

“…… Is not it?”

An ambiguous voice that doesn’t feel certain.

‘That incompetent bastard!’

At that question, the expressions of all the members of the Excellence Team were contorted.
