Who is George Bull?

If it is not the same name, the founder of Boolean algebra is this, and a little knowledge of computer science will definitely have heard his name.

Apparently, however, Mr. Bull had not achieved much at this time, and his presence here was rather unusual, after all, he was a mathematician, and he was a bit of an amateur, and he had only recently made a name for himself in academic circles.

It was not surprising to meet academic celebrities at Cambridge University, and after a period of chatting and laughing with Kelvin and Joule, Ma Whistle had long since adapted to this.

But Boole's case is a bit peculiar, because the work of the great mathematician has something to do with entropy, or some to Shannon.

Shannon's master's thesis, which shook the past and the present, was based on Boolean algebra.

"Please, Mr. Bull." Ma Whistle said.

George Bull: "This is a great discovery, but I have a question, if the increase in entropy does not seem to be a necessary event, as defined by this later formula? ”

"Theoretically, it does." Ma Whistle nodded, then stretched out his hand and gestured, "But as long as you estimate it, you know that even if it is just the air molecule in my palm, which may be ten to the power of ten, the probability of its entropy reduction is unimaginably low, almost impossible." ”

"We can set a probability, call it N, which refers to the probability of spontaneous entropy reduction visible to the naked eye."

Ma Whistle wrote a letter N on the blackboard, and then continued to hold the chalk and said, "How small will this N be?" I guess the probability of throwing chalk from one side to the other and having it write a Shakespeare poem on the blackboard is probably N. ”

Bull frowned slightly, as if he was still a little confused, but he didn't know what to say.

"I can probably guess what you think," said Whistle, "and in fact there were doubts that sprung up in my mind around the time of the birth of this formula, and I have written down many of them, and I will make them public in the near future." ”

Next, the question was asked, "Why can't entropy be defined as 'the degree of convertibility of energy', rather than the other way around?" ”

Ma Whistle: "You have such doubts, probably because you haven't understood my further explanation of entropy. If it is only used as a data for the study of steam engines, it does not hurt to define entropy in reverse, but obviously, entropy will not be limited to the field of steam engines, or even thermodynamics and physics......"

Hundreds of people in the audience raised their hands, and there were still many questions.

But the horse whistle doesn't have that much time.

In fact, he's already taking up a lot of extra time in the conference, and the next few speakers are already in line.

The line didn't go any longer, because it was obvious that it would have to wait until dark to keep it going.

"One last question." Ma Whistle pointed at a random person.

"The concept of entropy is somewhat obscure, but I have to say, you are an outstanding lecturer and I think I have understood the meaning of the word." The questioner said cautiously.

After a pause, he continued: "The law of entropy, or the 'second law of thermodynamics'...... It seems to reveal a devastating end – will our world eventually evolve into the most entropy, chaotic state, to extinction? ”

People responded to this question.

"yes, that's what I'm trying to say, this law is terrible!"

"I'd rather believe that this law is false."

"Alas, chaos, is this the end of the universe......" people were pessimistic.

Ma Whistle smiled slightly: "Do you remember what I said, the meaning of the word 'entropy' in the Apache language - the original calamity?" ”

"We must admit that this law reveals some unfortunate and pessimistic truths." He paced from the podium and said slowly, "The first law tells us that you can never win the universe, while the second law seems to tell us that you can't even tie the game. ”

"But things are not so absolute, after all, I also said that entropy reduction is theoretically possible, and even the reversal of the entire universe is not impossible."

"The ...... of the universe Reversion? ”

Ma Whistle: "Yes, I think the word 'reversal' is appropriate, because entropy also seems to indicate the direction of time, it is like the arrow of time, indicating the irreversible order. ”

"In fact, I seriously considered the reversal of the universe, or the reorganization, the regression, and got some mathematical results. But if we do, the other speakers at the conference will probably not have time. ”

The audience was hotly discussed.

Entropy seems to reveal the fate of the entire universe, and there are already mathematical results?

There is no doubt that no one wants to listen to anyone else's speech now, and people even feel that the speech of the horse whistle has just begun.

Ma Whistle didn't continue: "Sorry guys, I think I've taken up too much of the meeting time. If anyone has questions to discuss with me, we can do so outside of the meeting. ”

He looked at George Bull and gave him a suggestive look.

As one of the most important mathematicians of the nineteenth century, Boole was naturally worth dealing with.

"Or when my book is published, all the questions I can answer will be addressed in the book." "Thank you all for listening to my lengthy speech. ”

"Bang Bang Bang-" Two seconds later, the audience burst into applause.

Ma Whistle breathed a sigh of relief, sat back down next to Kelvin and Joule, and casually asked, "How are you feeling?" ”

"Yay!" Thomson laughed, "You're a natural lecturer and orator. ”

Joule also said: "That's right, I'm sure everyone here was convinced by you." ”

Ma Whistle smiled and didn't say anything.

Then, Thomson and Joule's smiles converged, and the atmosphere suddenly became a little quiet and awkward.

Ma Whistle also felt this embarrassment and drank water to himself.

It wasn't until about half a minute later that Thomson broke the embarrassment and said, "All of these are the problems you've already solved, including the ones you discussed with us...... Is that right? ”

As a future physics teacher, Ma Whistle inevitably had to pretend to be confused in the process of dealing with Thomson and Joule, pretending to discuss some questions that he knew the answers to.

There will always be flaws in disguise, and it is inevitable to say that you will occasionally leak your mouth.

It's just that all the while, Thomson and Joule didn't pay much attention and didn't realize that the horse whistle was pretending to be confused.

It wasn't until this speech, as Ma Whistle continued to throw out heavy content and performed a groundbreaking trick in public, that the two keen scientists finally recalled Ma Whistle's previous pretending to be confused and realized that something was wrong.

This Indian, who came from afar, has long since single-handedly built a near-perfect thermodynamic edifice.

The horse whistle was silent for two seconds and decided to tell the truth: "Indeed, there are some problems that I have already solved...... Frankly, I need your help, otherwise you can imagine that a British journal would not accept a barbarian submission. ”

"The paper on thermodynamic temperature scales was actually written by you a long time ago?" Thomson took a deep breath and asked again.

Ma Whistle: "Hmm...... Almost. ”
