After returning from the studio, Jiayi returned to his study and spread out his paper and pen to start writing.

Although he has been away for the past six months, he has not relaxed his research on magic, especially on thermodynamics just because he thinks about how to come back.

"The main equations of the thermal theory of mechanics are easy to apply" This is the title of his new paper. When he calculated absolute zero, he proposed the second law of thermodynamics. At that time, it was simply expressed as "it is impossible to transfer heat from low-temperature objects to high-temperature objects without causing other changes", and a description is completely from the perspective of heat.

The irreversible processes include heat conduction, work-heat conversion, and diffusion. These irreversible processes can all be summarized by the concept of entropy, that is, the irreversible processes occurring in the adiabatic system can only be carried out in the direction of entropy increase. Because the isolated system must meet the adiabatic conditions, and the spontaneous process is irreversible, the spontaneous process of the isolated system always increases the entropy of the system.

Entropy is a measure of the degree of system chaos and a function of the state of matter. When the state is constant, the entropy value of matter is also constant. It can be said that entropy change is only related to the initial and final state of matter.

ds>=δq/t, Jiayi wrote the formula on the manuscript paper, and at the end it said, "The energy in the entire universe is constant", while "the entropy of the universe tends to be the maximum", the greater the entropy of the system, the closer it is to the equilibrium state. Although the total amount of energy here remains unchanged, the less energy available for utilization or conversion is. The closer the entropy of the universe is to a certain maximum limit, the smaller the possibility of it changing, and the universe will always be in a state of inertia and dead silent.

After the paper was sorted out, he was about to submit the paper to the journal "Witcher". The mailing service of the chamber of commerce was carried out. He did not have to go to the Supreme Council or the Association of Mages to submit it in person. He just needed to package the paper and cover it with the mage key and submit it to the nearest postbox.

Although long-distance delivery is very slow, the delivery speed in Mosacher is still very fast, especially for mage letters, they will give priority to delivery.

After sending the paper, Jia began to study the printing of magic circuits.

Mosacher has a lot of materials and can be purchased almost all materials, especially now that the United Chamber of Commerce has relationships with multiple Chambers of Commerce and has richer procurement channels, so we have found more materials for Jiayi.

The blood of the monster is the richest. He even bought a bottle of the blood of the two-headed dragon. He could not buy the real dragon blood. The blood of the two-headed dragon is one of the best alternative materials. The replacement materials for the Nightmare Demon Grass are difficult to find, but he also found the Styx flower as a substitute.

But the effect of the experiment is hard to describe. He verified dozens of combinations of 5 or 6 materials in a row, but none of them succeeded.

...

Jiayi's paper was sent to the Witcher magazine and the Supreme Parliament. The papers of the Supreme Parliament soon entered the review stage and the papers were in Baldwin's hands.

Baldwin looked at the paper handed over by the person below: "Is there anything wrong with this paper? It's just a step further in the theory he proposed before and made a summary. However, this concept of entropy is somewhat interesting, representing the degree of chaos of objects. Is the higher the temperature, the more chaotic it?"

This does not really represent entropy, but it is easier to understand.

When Jiayi describes temperature, it is described by molecular thermal motion. The higher the temperature and the faster the molecular motion speed, it means that it is more chaotic, and there is no mistake.

The mage who handed over the paper said: "Look at the end, he proposed that the universe will gradually increase without decreasing, and will eventually approach the maximum value of entropy, and the universe will also fall into a dead silence."

Baldwin looked carefully at the part that the other party had just pointed out. Although what Jia Yi said was not very straightforward, according to this statement, it was to say that the universe would eventually go to destruction and was inevitable.

"I didn't expect Jiayi would agree with the theory of the end of the world." Baldwin's brow frowned in an instant. The theory of the end of the world is generally something that only religions have. God creates the world and God destroys the world. There are few mages who believe in this. He did not expect that he actually saw a paper that provides theoretical basis for the theory of the end of the world.

"Are we going to pass?"

Baldwin thought for a moment and said, "Perform according to normal. His theory cannot see any errors. We cannot refuse just like this. I will inform you on duty to see what your opinion is."

Wilmot, who was on duty, had no objection, and just copied a copy to Magnay and let the paper pass. Reji said that although it was not so pleasant, it did not affect the importance of entropy.

...

With a loud "boom~", Winnie felt the whole house tremble for a moment. He hurried to the door of the laboratory and saw Jiayi coming out of the laboratory.

"how's it going?"

As she said that, she looked at the laboratory and saw that the lab was in a mess, the table was exploding, and the ground was covered with ink paste made of cinnabar, which looked like a large piece of blood was sprinkled on the ground. However, there was no sign of explosion on Jiayi's body. Before the experiment, he used a shield to protect himself, and the explosion did not cause any harm to him.

Jiayi sighed: "It's not very ideal. Please help me clean up the bottom. I'll take a break. What's wrong with this?"

He murmured, with confusion on his face.

Winnie leaned her head and looked at the laboratory, turned around and whispered to Jiayi: "Boss, do you want to go outside for the next experiment? The explosion of your experiment is getting bigger and bigger, and I'm afraid our house can't bear it."

After saying that, she quickly left, trotted to the utility room, took a broom and rag to the laboratory.

Jiayi glared at her and shook her head and went out to bask in the sun.

Winnie stood at the door of the laboratory and turned around and said, "Boss, your paper is published, right on the desk in the study. What is it written on it? What is entropy?"

"My lab is so messy, which is an increase in entropy."

When he arrived at the study, Winnie had turned the magazine to the page of his paper. He picked it up and took it and took a look. It was written by him himself, and there was nothing more familiar to him here than himself.

After a glance, he put down the magazine and went out. He was going to go to the studio to see how Fesden and his team's experiments were going.

By the way, he moved his experiment to their studio, and he was also the major shareholder of the studio. Winnie was right. If she continued to explode in the underground laboratory at home, the foundation of his house would be unstable.

...

...

The west area of ​​Moshache Wharf is almost the most remote and chaotic place in Moshache. The hardworking, thieves, wanderings, and various personnel are mixed here. Even the city hall does not know how many people there are. Characters such as sheriffs rarely appear here. This is almost the slum of Moshache.

In a house in the west of the dock, two mages, one tall and one thin, stood in front of a man with a hood. The mage said, "Empress, Jia Yi is back."

"He has finally come back. It's almost a year. This time, I must not let him run away." The messenger's tone revealed a lot of bitterness.

Almost a year ago, he came to Moshache with the order of the high priest of the Doomsday God Cult, and brought a powerful curse item. The god who claimed to be able to kill Jiayi was unaware of it, but he didn't expect that Jiayi went to Moshache as soon as he arrived here, and even went there for nearly a year - they didn't know that Jiayi was in a small world, and they thought that Jiayi had been staying on the Elf Island until now.

The messenger at Mosacher was always worried and did not dare to go out casually. He was afraid of being discovered. He changed several places and finally came to the west of the dock. The chaotic environment here made him feel more secure, but it was not very comfortable to live. He could always smell the stinking sewage and the editor's smell when he was sleeping.

Unlike the two tall and thin mages, they have almost integrated into Moshache's mage group with the help of the Three Kingdoms Killing Cards, and their living environment is much better than that of the messengers.

"How do you know he's back?"

The messenger's tone was not very friendly, perhaps because the two tall and thin mages had driven him out of their residence.

"We've been monitoring him and finally found out he's back lately, and he has published a paper."

As he said that, he handed over a magazine to the messenger.
Chapter completed!
