Chapter 128: Conservation of Energy

Jia Yiyi did ten sets of experiments in a row, pulled over a blackboard, and wrote all the data on it. On the left is the amount of work done by the machine, and on the right is the increased heat calculated from the temperature and specific heat capacity of the solution and the blade.

The data on both sides were listed, and Jia Yi turned to the audience below: "The theory of thermal mass actually has many meaningful results, such as how to quantify heat. If we look at the mechanical work on the left and the heat on the right, I define a unit of mechanical work, named coke, defined as the work done by one attrem, and we can see that there is a very obvious linear relationship between the two sides. “

As he spoke, he drew a coordinate system on the blackboard, the horizontal axis, the heat and the vertical axis, and all the points basically fell on a straight line.

"If you do the math, you can see that the linear relationship between the two sides is around 4.17, and this value is what I call the thermal work equivalent. If the thermal mass really exists, this linear relationship cannot be explained at all, and it can be inferred that in addition to mechanical work, electrical work still conforms to this law, although the coefficients may be somewhat different. ”

Looking at the results of Jiayi's calculations on the blackboard, Laurent wanted to refute, but he couldn't find the entrance to refute at all, and stood stunned all the time, and the people below were a little stunned, whether they agreed or opposed him, they began to calculate silently in their hearts to verify Jiayi's process and results.

"There doesn't seem to be anything wrong with that. A mage looked at his companion with some uncertainty, "Is there any negligence in the calculation process?"

"No, I can't see any problems in the calculation process, such a simple process, if there is really a problem, someone would have raised it a long time ago, but his several sampling data are relatively concentrated, it is better to expand the sampling range, so that it is more accurate, if it is still true in a large range, then..."

"Heat is dangerous. ”

Could it be that the newly emerging heat theory has been eliminated like this?

The mage who spoke was still a little incredulous, with a sense of unreality.

Heat has not appeared for a few years, but it can have so many fans and have such a great influence because heat is closely related to almost everyone, but it lacks a complete set of theories, and the theory of heat mass is simple, but it has solved many problems and produced great results.

Therefore, after the thermal mass theory overthrew the phlogiston theory, it quickly ascended.

But now, when everyone thought that the theory of heat mass would become another monument after the theory of gravitation and electromagnetism, it was smashed by this young mage on the stage.

It gave everyone a dreamy feeling, including Frietus, who organized the presentation. Originally, he only hoped that it would be good for Jia Yi to be able to stand firm under the challenge of hot quality.

Kaichi paused for a moment to give everyone a space to think, and then continued: "There is a very important point in the theory of thermal mass, that is, thermal mass is conserved and does not increase or disappear out of thin air. ”

"Yes, if there is no heat mass, then heat can not be conserved?" Hearing this, Laurent seemed to grasp the last straw and retorted to Jiayi.

Jia Yi looked at Laurent with some pity, since he himself proposed it first, of course he had already found a way to explain.

"Of course not. We can see that mechanical work produces heat, and there is an obvious linear relationship between the two, because mechanical work is converted into heat through friction, and heat is not increased out of thin air, but obtained by mechanical work. I summarize this phenomenon as – conservation of mechanical energy.

"Heat can be transferred from one object to another and can also be converted to and from mechanical energy or other energy, but the total value of the energy remains the same during the conversion. By extension, we can think that not only mechanical energy, but also energy is conserved. ”

......

"Conservation of energy, this, is this the law of conservation deduced by analogy with the law of conservation of mass and the law of conservation of pillars? ”

"I don't know if energy is conserved, energy conservation is not conserved, but I am afraid that the heat mass theory is hopeless, and the conservation of mechanical energy can completely replace the hypothesis of heat and mass conservation. ”

Compared with the theory of thermal mass, this set of theories is more perfect, it is unimaginable that he made it alone. ”

......

The audience couldn't help but be noisy, discussing with each other the conservation of mechanical energy and energy proposed by Jiayi, as if suddenly a swarm of bees came, buzzing...

Laurent sat down in his seat in some dejection, feeling that his life was gloomy, and what he had insisted on for so long to think was the truth was shattered.

"No, Master Laurent, it's not true, his theories haven't really been verified, there must be loopholes, let's go back and check it, we will definitely be able to find out his loopholes, he is only because he proposed a new set of theories, we are not familiar with it to be so passive, we will definitely be able to find loopholes. ”

The mage who came with Laurent was not reconciled, and was still making the last struggle, and his speech was a little incoherent.

Laurent came back to his senses, felt that he had grasped another straw, and said: "Yes, his theory only seems to be perfect, there must be mistakes and omissions, I will go back and start experiments, and I will definitely be able to find out his mistakes." ”

Jia Yi's speech was very successful, it was like dropping a super invincible enhanced version of the big fireball in Moshacher, not only the sound and light effect was excellent, but also added a layer of heat to the entire Moshacher, and his name had already spread completely in Moshacher before Jia Yi's speech paper was officially published.

Not everyone agreed with Jiayi's theory, and for a time, many people began to calculate the relationship between heat and work. There are more and more people who measure it, the range of measurement is getting wider and wider, the thermal work equivalent is becoming more and more stable, and the conservation of mechanical energy and even energy conservation is more and more convinced.

With the success of Jiayi's paper, the conservation of energy has begun to slowly take root in the hearts of the people, and it seems that people have forgotten the theory of heat and mass, and at the same time forgot Laurent.

......

......

Laurent had been locked up in the lab for days, when his assistant knocked on the door and whispered to Laurent, "The latest magazine has arrived..."

He wanted to continue, but looked at Laurent, and he couldn't say anything.

Laurent glanced up at him: "What's the matter, what do you want to say?"

Laurent looked very haggard, his face was not bloody, his eyes were bloodshot, and his hair was a mess, as if oil was dripping out. It can be seen that he hasn't taken care of himself for a long time.

The assistant hesitated for a moment, and said in a low voice: "Three more mages have issued a joint statement, their verification of the thermal work equivalent is accurate, and the error is within the allowable range, this is already the forty-eighth statement, and the calibration range ranges from a few coules to tens of joules or even tens of thousands of joules, and there is no problem." ”

Laurent looked flat and not surprised at all: "I know, because my own check results are the same, the mechanical energy is conserved, it is correct." So far, at least, true. ”

His voice was a little hoarse and low, as if two pieces of sandpaper were rubbing, but it didn't sound too excited, not as irritable as when he had just returned from Kaichi's briefing.

These days, the supporters who originally surrounded him have disappeared one by one, and when he first entered the laboratory, people often came to look for him, but slowly, with more and more research results on the conservation of energy, fewer and fewer people came, and now, no one has come for many days.

We can modify the theory of heat and mass to make the heat and mass fit these phenomena, and the heat work transformation can also be expressed in terms of heat mass, and the conservation of mechanical energy is also developed on the basis of the conservation of heat and mass. ”

Laurent was silent for a while and shook his head: "Of course you can, but it's not necessary, if you want to make heat and mass perfectly explain these phenomena, then you need to set many conditions, and latent heat alone is not enough." Have you ever learned the razor principle? If both theories are true, then the simplest one is correct. If we set so many conditions, it is better to just remove the heat mass, which is also true, so why do we need to introduce heat mass? In the law of conservation of mechanical energy and energy, there is no place for heat mass. ”

"If it is not necessary, do not add entities", this is the core idea of the razor principle, if there is no such thought, then all theories can be infinitely expanded, for example, the mass can be split, thinking that it is composed of mass 1 and mass 2, but if there is no corresponding phenomenon and calculation results to support, such a split is completely meaningless.

It's always easier to put something in there, according to the theory.

Laurent glanced at his assistant and said softly: "You leave the magazine and go out first, don't come in without my greeting." ”

In his words, he seemed to have an indescribable tiredness.
