After Xiao Yuan's persuasion, Liu Dong seemed to fall into deep thought, until the lecture began, most of the time he kept his head down and did not speak, only Duan Yanyue came to the stage, introduced the professor who gave the lecture, and announced the start of the lecture, he raised his head, stared at the shadow on the stage, and did not let go.

The professor who gave the lecture was named Smith Bull, an old man in his fifties from the University of California, Berke, who was working on a research he was working on, specifically on the topic of a review of the research on network chaos systems.

The chaotic system is a kind of individual disorder, but the overall development of the orderly evolution process, the science of the study of the chaotic system is called chaos, the mathematical model of the chaotic system created by chaos science is called the chaotic model, the initial state of this model and the ancient myth of the Chinese kingdom Pangu opened the world to tell that the world is not opened is very similar, because the individuals in the system have not yet begun to move, so the whole system will be in a completely disordered state.

This disordered initial state will gradually evolve when the individuals within the chaotic system begin to move, and under the influence of all disordered individuals, the whole chaotic system will develop in an orderly direction.

"Lost a horseshoe nail, lost a horseshoe; lost a horseshoe and broke a warhorse; Broke a war horse and lost a king; Lost a king, lost a war; Lost a war, lost an empire. ”

Smith now typed out this passage in English on the slide, accompanied by a Chinese explanation.

"First of all, thank you to the beautiful Miss Duan Yanyue for helping me translate this text into Chinese." Smith first expressed his gratitude to Duan Yanyue, who was sitting on the side of the podium, in Chinese, probably because he felt that his Chinese level was really limited, and after a few words of hard work, it gradually became an all-English lecture.

Xiao Yuan's reading ability is very good, but his listening level, because he has received little training, is quite limited, fortunately, the old man's voice on the stage is very pure, and he is not too fast, combined with the very detailed projection, he can understand a seven, seven, eight, eight.

However, Jiang Hua looked uninterested, not interested in the content of the lecture at all, and after looking around at the beautiful women for a while, he felt bored, and fell asleep on the table.

Liu Dong sat very upright and listened very carefully, but Xiao Yuan didn't know if his English level could reach the level of complete comprehension, but looking at his thoughtful expression, it should be about the same.

One of the most important arguments in chaos science is that the development of chaotic systems is very sensitive to the influence of some external factors, and some seemingly very small effects will gradually amplify their effects over time, just like the classic horseshoe nail story that Smith played in order to introduce chaos, although the horseshoe nail is small, it can eventually destroy a country.

What Smith said made Xiao Yuan easily reminded him of the butterfly effect, the weak influence of a butterfly's wings on the airflow may cause a hurricane, and the Chinese ancients said that the difference is a thousand miles, which is all about this truth.

Listening to Smith's explanation, Xiao Yuan had a preliminary understanding of what a chaotic system was, and then thought that the real world is also a big chaotic system, locally, everyone is doing everyone's things, different, this is local chaos, that is, chaos in chaos, but from a macro perspective, all people's activities are regarded as a whole, then, this whole is regular, everyone, even a baby, his existence will have a greater or lesser impact on the world, Even under certain conditions, a seemingly extremely small impact will be gradually amplified, and even change the historical development trend of the entire society.

"I just don't know what kind of impact I, a reborn butterfly, will have on our real world, and what kind of impact will it have on people who have intersections with me, or even those who have not?"

Xiao Yuan thought to himself, he turned his head to look at Jiang Hua, who was sitting next to him and fell asleep on his stomach, and thought that if he hadn't been reborn, I am afraid that there would not be a person named Xiao Yuan in this guy's life, and he would not have appeared in such a boring lecture for him, and he fell asleep.

"What about Liu Dong?"

Xiao Yuan glanced at Liu Dong again, and a thought also turned in his mind, Liu Dong seemed to feel that Xiao Yuan was looking at him, turned his head to look at Xiao Yuan, and said in a low voice: "This chaos science is very interesting, there are teachers in the School of Mathematics who are studying this thing now, I once listened to one of his lectures, and it was also about this, but that teacher studied pure theory, and this foreigner's research was more specific, and some of his achievements were to apply chaos systems to specific disciplines." ”

Xiao Yuan smiled, did not answer Liu Dong's words, but continued to focus on the podium and listened to the lecture carefully.

“…… Over the years, my research group and I have been committed to using chaos science to study the existence of the Internet, and using chaotic systems to model network systems...... "After outlining the theory and application scope of chaotic systems, Smith began to focus on their research content - network chaotic systems.

After an initial account of their research, Smith seemed to feel that the response to his lecture was not particularly enthusiastic, and he simply ignored the boring mathematical derivations and mathematical expressions that most people couldn't understand, and quickly flipped back a few pages before throwing out a point that made everyone feel excited.

"If we look at the Internet as a whole system, this system obviously has all the characteristics of a chaotic system, everyone's activities on the network are disorderly, but from a macro point of view, the network is an orderly system, and even we find that this system is alive, it will get hurt, it will get sick, and it will even get sick......

The students who were listening to the lecture below were clearly attracted by Smith's point, and as he threw it out, there was a burst of whispers from below.

"It's a novel idea to think of the Internet as a living organism." Liu Dong said.

"Maybe we can design such a program and let it simulate the operation of a chaotic system, or even put it on the Internet, so that it can develop freely in the chaotic environment of the network, and I don't know what kind of thing it will grow into in the end?" Xiao Yuan said on a whim when Liu Dong was talking to him.

"How do you have such an idea, is it technically possible?" Liu Dong turned around in surprise, glanced at Xiao Yuan and said.

"Only the unthinkable, nothing can't be done." Xiao Yuan said.

"It's a crazy idea, if you're ready to write it, let me know and I'll see what you can get out of it." Liu Dong said.

“…… How similar is the virus of the computer virus and the human body, it will destroy the network system, and the network system is the same as the human system, it also has a very strong immune system, and many antivirus software and firewalls running in the network are like white blood cells, which will kill these viruses, although the users of these software are simply maintaining their individual security, not realizing that these software have become part of the immune system of a system, but it is precisely this kind of unconsciousness, Promote network systems to conform more and more to the characteristics of chaotic systems......"

Smith is still telling his point.

“…… If computer viruses and security software are the destroyers and immune systems of the network system, then the hackers who create viruses are like some heavily polluted factories in reality, emitting a disgusting stench and developing those disgusting malicious programs......

It seems that Smith has a very bad impression of hackers, and soon the computer virus is involved in hackers, and his words instantly become sharp.

Other students may not feel anything, but Xiao Yuan noticed that when Smith mentioned hackers, the word he used was hacker. This word is a kind of faith for him, but the old man on the podium is attacking it with the worst words, his brows can't help frowning, and he even wants to stand up and interrupt the other party's words and defend him, but in the end he decided to endure it, and before the end of the general lecture, there will be a Q&A session, and he decided to wait until this link, and then discuss this issue with the old man on the stage.

The reason why Xiao Yuan decided to discuss this issue with the old man was because this was a lecture, and there were hundreds of people who listened to it, and the old man Smith's prejudice against hackers would be conveyed to everyone here, and he just had the aura of a famous foreign scholar, and the result could only be that people's prejudice against hackers was further deepened.

And Xiao Yuan felt that if he discussed with Smith in public, even if he couldn't convince the old man to recognize his concept of hacking, he believed that the audience sitting below would not be the same as everyone, after listening to his explanation, there would inevitably be a group of people who would go to verify, as long as there was one person who recognized his concept, he felt that he had achieved his goal, from this point of view, he had subconsciously regarded himself as a preacher at this moment.

Smith's lecture lasted for more than forty minutes before it ended, and the next time, Duan Yanyue came out again and began to organize people in the audience to ask questions.

Probably because most of the students were very interested in what Smith said, and his explanation was only to the point, all the students had a lot of questions, and when Duan Yanyue announced that he could raise his hand to ask questions, many people immediately raised their hands, and Xiao Yuan also raised his hand.

"That classmate, you come to ask questions." Duan Yanyue saw Xiao Yuan raise his hand, and was the first to call him by name.

"Hello, Mr. Smith, your lecture has opened me to a subject and field that I have never touched before, and I have a few questions that I would like to discuss with you, is that okay?" Xiao Yuan first politely said some opening remarks, in order to make everyone hear clearly, he did not use English, but directly used Chinese.

"Okay, excuse me, I'll discuss it with you." After listening to the translator next to him translate for him, Smith nodded and smiled at Xiao Yuan.
