In 1967, Harvard psychology professor "Milgram" tried to prove that it only took an average of five intermediaries to contact any two Americans who did not know each other, based on a chain of letters.

This phenomenon does not mean that the connection between any person and other people must be connected through the six levels to produce a connection, but it expresses the important concept that any two people who do not know each other can always have a necessary connection or relationship in a certain way. Clearly, with differences in contact and ability to connect, there will be a clear difference in the opportunities to achieve one's expectations.

Harvard, as a prestigious university that has always been ranked first in the world, has long been admired by Zhang Ning.

Alone in a foreign land, Zhang Ning, an Internet tycoon who is still somewhat famous in China, but walking on the streets of Harvard, he is no different from other ordinary people, and no one knows him. Like any other student, Zhang Ning occasionally goes to Harvard for classes, and occasionally travels to Cambridge, Massachusetts.

On the podium, the professor named Buenos was talking about a mathematical theory that many people had not heard of.

"This theory is called the theory of six degrees of separation."

"Guys, if you want to know the President of the United States, maybe you don't think it's possible. However, it is possible for everyone to know the president of the United States, isn't it? ”

"Professor Buenos, your theory of the six divisions seems to be very interesting. However, what I want to ask, Professor, is what does this mathematical theory have to do with our Internet. ”

A student stands up and asks the professor a question.

"That's a good question."

Buenos seemed to be ready to answer this question for a long time, "This is also what I will talk about later. Regarding our Internet, since its birth and development to the present, people have always thought of the Internet as a virtual Internet. There is a saying in China that says that on the other side of the Internet, you never know if the other party is a person or a dog, and it is also talking about the virtual Internet. However, I think that in the future, our Internet should be transformed from virtual to real. I have always believed that the Internet is not for everyone to hide and seek, it is for our real life. ”

"Of course, maybe if I say that, many students will have more opinions. Or, in the process of transforming from a virtual Internet to a real-name Internet, we will encounter more problems. For example, how to deal with the real-name system, and how to protect Internet privacy. I think there will always be a way to solve these problems in the future. And the theory I mentioned may give you some inspiration. Can we try to use this six-degree segmentation theory to build another new ecological network service in the current Internet? ”

Looking at Bu Yinos's continuous explanation on the podium, Zhang Ning benefited a lot in his heart.

It seems that it is the right thing to come here.

The United States is the birthplace of computers and the most developed place in the world for the Internet.

It is also one of the most powerful countries in the world in science and technology.

He has a lot of things, are world leading, and even, his theoretical knowledge. Perhaps Buenos did not know that the theory of the six degrees of division just mentioned may be taken to the extreme in the near future.

"Okay, that's all for my class today, you can think about it more when you go back. We at Harvard are happy to see our students innovate in all areas. ”

After a class, Buenos officially finished class, and Zhang Ning also returned to his apartment.

In order not to be disturbed by others, the apartment where Zhang Ning lives is a Harvard single apartment.

After class and dinner in the afternoon, Zhang Ning threw himself into the apartment, ready to build a website.

This website is called Facebook, which literally translates to Facebook, which is the world's first social Facebook network.

After creating QQ space in China, Zhang Ning has realized that the future of social networks will be unstoppable.

Perhaps, it won't be long before the concept of social networking will become popular all over the world in the distant United States.

Although Zhang Ning's QQ space can be regarded as attracting a lot of attention in China, with the current Internet environment in China, even if he is popular, it is impossible to affect the world. Like, QQ is already the hottest instant messaging in China, and it is also the instant messaging with the largest number of people online at the same time in the world. But so what, it still can't attract global attention.

If you want to enter the world and influence the world, then Zhang Ning can only start with the United States.

Therefore, Zhang Ning had to hurry up and create the most well-known Facebook network in later generations.

At 2 o'clock in the morning, Zhang Ning finished writing the code.

As usual, Zhang Ning will log on to Harvard's intranet if he has nothing to do.

The so-called intranet of Harvard is actually the same as the intranet of Tsinghua University. However, Harvard's intranet is undoubtedly more popular and well-known than Zhiyan Da Mizuki. Every day, in the Harvard intranet, Zhang Ning can see a lot of new things, as well as the latest theories, and a lot of messy whimsy.

A few days ago, Zhang Ning saw a discussion on the development of digital music in the Harvard intranet.

However, Zhang Ning is not particularly interested in so-called digital music.

In today's development of the Internet, even if online music rises in the future, it can only be regarded as a niche product.

Hey, it's a lively day.

Looking at the total number of posts posted by Harvard, it is obvious that it is 3% more than usual.

Zhang Ning attacked the computer, a subreddit with the most posts.

At this time, there is a post that has been replied to for more than a hundred pages.

When I opened it, I didn't expect it to be a lovelorn moaning on the forum.

However, this lovelorn is undoubtedly more bullish than the other lovelorns.

This friend whose ID is called Mark, and his first post was to complain about his broken love. has been saying that a good man like himself should be liked by all girls.

Originally, a post like this couldn't attract too many people to watch, even if someone watched, it couldn't be so popular.

What really made this post popular was because the owner of this post said a word.

Starting today, I'm going to do something big. One thing, a big event that caused a sensation throughout Harvard.

For this reason, around this major event, it quickly attracted countless Harvard students to watch.

Haha, I know this Mark, this guy is said to be a computer whiz, but it's a pity that people are too Muna. doesn't know how to please girls, and as a result, he fell out of love and then fell out of love.

Quite a few people started leaving comments under this post.

I'm more concerned about what big things this Mark is going to do.

yes, me too, it's a sensation all over Harvard, I really want to know what this is?

Zhang Ning didn't follow to post, but he knew that even a prestigious school like Harvard had too many boring students.

As for what big event to make a sensation at Harvard, it is estimated that it is a joke, of course, even if there is, it will not cause a sensation.

Zhang Ning closed the post and prepared to browse other content.

It's just that at this moment, he suddenly felt that the number of Jù in Harvard's intranet suddenly became a little abnormal.
