Then, the two opened the note, only to see that it was written with the name of one person:

"Kano."

"Professor Thomson, it seems that we see something in common." Ma Whistle said with a smile.

Thomson was taken aback for a moment, then smiled and said, "Yes, or rather—we are all believers in Kano. ”

The Carnot cycle is destined to be an unforgettable memory for future generations of physics learners, and its originator, Sadie Kanot, is undoubtedly the most important early founder of thermodynamics.

In fact, more than twenty years ago, the young French officer gave an estimate of absolute zero, which is close to the truth.

Had it not been for Carnot's untimely death, the formal establishment of thermodynamics would probably have been ten years earlier – the cause of his death was cholera, which led to the burning of his relics, including a large number of research materials, and the development of thermodynamics was frustrated.

Of course, the death of such a genius, although it slowed down the development of thermodynamics, did not prevent it.

In the year Kelvin was born, Kano published his thoughts on absolute zero.

And just a dozen years after Carnot's death, the young Kelvin took over this mission and officially proposed the absolute temperature scale.

Now, the traverser horse whistle is undoubtedly going to have a kick in the way.

"To design a temperature scale, you first need to establish its zero point." Ma Whistle said slowly, "For the scientific temperature scale, its zero point should be the lowest temperature in nature, absolute zero. ”

“…… Sadie Kano's work in 1824 is a good example of how we should build on him and take it a step further and design a true 'absolute temperature scale', or 'thermodynamic temperature scale'. ”

Thomson agreed: "Yes, your and Joule's paper has actually revealed the inevitability of the birth of this temperature scale. ”

"You said in your paper that 'the essence of temperature is the average kinetic energy ...... molecules,' and I think the thermodynamic temperature scale is already coming out here."

Now Thomson was fully convinced that the Indian in front of him was indeed the author of the paper, a physicist of rare talent.

He even had a vague sense that Ma Whistle's understanding of thermodynamics and even physics as a whole was much deeper than his.

Of course, Thomson eventually dismissed this vague feeling, because he didn't believe that anyone could understand physics far beyond himself, even some condescending old fellows in the academy.

But in any case, it is indeed amazing that an Indian, who is regarded as a savage in the popular mind, has such a level of physical attainment.

It is no wonder that Joules praised the horse whistle in his letters, and even blew a wave of Indians.

"It's much easier for us to establish an absolute temperature scale." Thomson said, pulling a journal from the stack, "We now have exact experimental data. ”

Ma Whistle: "Is it the data published by Professor Victor Regno last year?" ”

"Looks like you've read that paper too." Thomson nodded, flipped the journal in his hand to one of the pages, "Actually, the author, Mr. Regno, was one of my mentors, and when I went to France three years ago, I spent some time in his laboratory, and he benefited me a lot. ”

The two read the experimental data published in this journal and discussed for a long time.

“…… Based on Mr. Regno's data, we can conclude that absolute zero should be -273 degrees Celsius. Ma Whistle said.

Thomson: "Yes, -273 degrees Celsius, the limit of gas compression. ”

The origin of absolute zero is the limit of gas compression, and it has been found that the lower the temperature of the gas at a constant pressure, the smaller the volume.

Then a natural idea was born, when the volume of the gas is compressed to close to zero, the temperature at this time should be the lowest temperature in nature, after all, the volume can never be negative.

Of course, this idea was still flawed, and it was not until the early twentieth century that Nernstein's theorem was formulated.

And the deeper mathematical proof is in the 21st century.

It's too early for this era to think about things like Nenste's theorem, and the horse whistle now only needs to follow the ideas of Carnot and other predecessors, take out the absolute temperature scale, and then do a little bit of work.

"Oh, sorry, I seem to have a class, I have to go teach the students first." Thomson and Ma Whistle discussed for several hours, until he realized that there was still a teaching task to be completed, glanced at the time, and hurriedly stood up and spoke.

Ma Whistle nodded: "Classes are more important, I can understand." ”

"You seem to be a teacher too?" Thomson said.

Ma Whistle: "I am the chief of the tribe, and I not only want to lead my people to defend their homeland, but I also need to tell them this knowledge. ”

"That sounds ...... It's funny. We'll continue to talk after the lesson. Thomson hurriedly imagined the scene of the horse whistle lecturing on physics to the many feathered Indians, and then walked out of the office with the handout.

After Thomson left, it was not easy for the horse whistle to go out and hang out.

Although it is a university, it is not much more civilized than the city. He went out with a yellow face, and it would be an unnecessary trouble to run into someone like Mackintosh again.

So he simply wrote a thesis, the title of which directly plagiarized the original work of the historical Kelvin "On an Absolute Temperature Scale", and the content was naturally the same as the title.

Since Ma Whistle had already written a whole book of "Thermodynamics" in advance, he hardly needed to think about the content of this paper, and he wrote quickly.

There are only a few references to Kelvin that need to be paused, and he disguises the paper as the result of his discussions with Kelvin.

He wasn't going to be exclusive, he even put Kelvin's name before himself.

After all, in his opinion, this is not a very important paper. In contrast, he needed to rely on Kelvin's influence more.

Thomson finished his day's teaching, and when he returned to his office, he found the horse whistle studying a few pages of manuscript.

"What is this?" He asked casually.

Ma Whistle: "I've written our previous discussion into a paper, you can see if there's anything wrong." ”

Thomson was stunned for a moment, took the manuscript and read it for a moment, and couldn't help but say in surprise: "This, this is what you wrote in two classes?" ”

"yes, what's wrong?" The horse whistle looked unimpressed.

Thomson was silent for a moment: "Have you been writing articles so fast?" ”

As a recognized genius and the youngest professor of physics at the University of Glasgow, he has written papers very quickly, and colleagues often marvel at his quick thinking, which he has always prided himself on.

Until now......

Although the article is not long, it is a thesis after all, and it is indeed a bit strange to get it done in about two classes.

Thomson felt that the speed of copying an article was no more than that.
