"Thanks for the reminder, Professor." The horse whistle smiled.

Professor Smith said no more, and led the men to the lodgings arranged for them at Cambridge University.

As one of the world's top universities, the University of Cambridge is naturally very well underwhelmed, and Ma Whistle even tasted tea imported from the Qing Dynasty here.

And it is not ordinary imported tea, and the Chinese on the packaging makes Ma Whistle can't help but be fascinated for a moment.

"Jardine walk......" he said silently.

"Jardine Hong tea is the best tea in the world." Thomson doesn't know Chinese, but he clearly knows Jardine House.

"It's rare for Cambridge to be so generous, I didn't have that kind of treatment before." Joule carefully took the freshly brewed tea, and at the same time couldn't help but complain.

Thomson laughed, "Haha, you're almost a member of the Royal Society." ”

"Whistle, what's wrong with you?" He noticed that the horse's expression seemed a little strange.

"Nothing." Ma Whistle said perfunctorily, looking away from the Chinese characters.

Thomson's brows moved slightly: "You know Chinese characters?" ”

Ma Whistle hesitated for half a second, then smiled: "I understand a little, in fact, I have studied many languages, English is one of them, and so is Chinese." ”

"Really?" Thomson and Joule were surprised, "Show us your hands, to be honest, I'm a little curious about how you speak Chinese." ”

"Let's talk about it later, now our priority is the next meeting." Ma Whistle said.

Soon, with the arrival of physicists from all walks of life, this academic conference kicked off at the University of Cambridge.

The conference was held in a large auditorium filled with scientists from all over Britain and Europe, as well as students and faculty from Cambridge University, as well as a number of journalists, totaling a thousand people.

In an era when there were no microphones, such a scene was obviously extremely unfriendly to the speaker.

Among the thousands of people in attendance, it was no surprise that sitting in the C seat was Michael Faraday, a thin old man with gray hair and heavy bags under his eyes.

Looking at Faraday, who was surrounded by everyone, Ma Whistle suddenly thought of a photo in later life, which was also a scene of an elderly physicist surrounded by a large group of people, but the protagonist was Yang Zhenning.

Originally, nascent thermodynamics was only one of the topics of this academic conference, and it was not even the most important topic.

However, since the whole of Britain was discussing the horse whistle, one of the founders of thermodynamics, discussions outside of thermodynamics were inevitably neglected, and it can even be said that almost everyone was waiting for the Indian to speak on stage.

This is especially true of Mackintosh, and in fact that's why he's here for this conference.

He wanted to see if the Indian who had humiliated him was a shameful academic liar at all – preferably.

"Oh, it's finally his turn, that Apache." There was a burst of discussion, and Mackintosh, who was almost sitting in the back row, cheered up and looked at the podium at the front of the auditorium.

"Let's welcome Mr. Whistle." The meeting was chaired by Professor Smith.

There was a modest round of applause in the auditorium, and more people were looking at the necks so they could see the Indians walking towards the podium.

Sadly, many people don't see some of the scenes they imagined, such as a wild man dressed in animal skins.

The horse whistle was dressed entirely as an English gentleman, in a neat black dress, and if it weren't for the skin color of the other attendees, he looked like a young teacher teaching here.

"Ladies and gentlemen......," said the horse, as soon as he opened his mouth, he made a joke.

This would have been a very common opening statement, but the problem is that there don't seem to be any ladies here.

It was an academic meeting, and quite an important one, and in 1848 it was almost impossible for a woman to be present on such an occasion.

There was some laughter in the auditorium, but the horse whistle didn't care.

"Not long ago, my friend and I proposed the name 'thermodynamics' in our paper as the name of a nascent discipline. Some people may feel unimpressed by this, but I can fully understand that, after all, this subject is so immature, like a baby......"

Faraday, who was sitting in the first row, couldn't help but smile when he heard this. After all, more than ten years ago, in a similar scene, he also compared his discovery in the field of electromagnetism to a baby.

"Although thermodynamics is as immature as a baby, I believe that the birth of this discipline is inevitable for the development of physics, and it will surely grow into one of the most important branches of physics, like mechanics and electricity." The horse whistle continued.

"In fact, thermodynamics has been gestation for a long time, especially in recent decades, with the discovery of the Earl of Rumford, people have gradually become aware of the nature of heat......"

As a physics teacher, for him, standing on the podium and lecturing physics is simply an instinct, like eating and drinking.

After a while, he was completely in the groove, talking endlessly, and even having a bit of a professional habit.

"Look at the blackboard." After writing a few lines of formulas on the blackboard, Ma Whistle knocked on the blackboard casually, causing the professors in the audience to look at each other.

"He seems to treat us like students......"

"What a megalomaniacal guy!" Some of the old professors couldn't help but be annoyed, "No one dares to talk to me like that!" ”

"To be honest, I think he spoke really well, and after listening to what he said, I was completely convinced by him that thermodynamics must be one of the most important branches of physics."

"He was indeed a physicist, unbelievable, an Indian scientist ......"

People were talking.

Ma Whistle talked about the history of physics for half an hour, and even the layman reporters listened to it with relish, they may not know the formulas, but they can understand the stories of the physicists.

As the narrative progresses, he speaks of the law of conservation of energy.

Ma Whistle: "I think most people here have accepted the 'Law of Conservation of Energy,' or the 'First Law of Thermodynamics.'" ”

"This law tells us that energy does not arise or disappear out of thin air, it can only be transformed from one form to another...... From this we can be sure that a perpetual motion machine cannot be made, and all attempts at a perpetual motion machine are doomed to failure. ”

Before the words fell, the auditorium once again resounded with a dense discussion.

Perpetual motion machines are a hot topic.

Due to countless failed attempts by their predecessors, the vast majority of scientists have basically realized that perpetual motion machines cannot be made.

But it was only in recent years, with the discovery and popularization of the law of conservation of energy, that scientists really died of this heart.

"It's a shame that the law of conservation of energy pronounces the death penalty for perpetual motion machines, and we can't get the device of this dream......"

"Maybe we can envision another kind of energy device, such as letting the temperature of seawater drop and extract energy......"

In the midst of all this talk, it is not surprising that Ma Whistle heard something about the second type of perpetual motion machine.

So he went on to say: "Since energy can only be transferred, can we design such a device, although it can't create energy, it can extract energy from things that have a huge amount of energy, such as the ocean, we only need to make the world's water drop by one degree Celsius, and the energy obtained from this may be enough to make a train run for 100,000 years." ”

"That sounds good......" the people said.

"What do you think?" Joule looked at Thomson beside him.

"Hmm...... My gut tells me that it doesn't seem like possible. Thomson mused.

Ma Whistle let the people talk for a moment before he said, "However, I am sorry to tell you that such a design could not exist either, and in fact I think it could be called a 'perpetual motion machine of the second type', which is just as ridiculous as a perpetual motion machine of the first kind." ”
