1. The principle of six degrees of separation suggests that everyone on this planet is separated by only six other people. In other words, our society can be easily navigated by different kinds of social links, which would create a network of about 6 billion nodes where any pair are on average 6 links from each other.
2. World Wide Web was invented by Berners-Lee around 1990; this is the pre-internet society. It was a virtual network in which Webpages consisted of much information such as news, movies, gossips, maps, etc. However, people today have discovered that it is not the overall size of the Web, or the number of Webpages created, that is important; what is more crucials seems to be the distance between any two pages.
3. Compared to the six degrees of separation in people of the society, scientists estimate that the diameter of the Web was close to about 19; nineteen degrees of separation. Six and nineteen seem to be drastically different, but what matters most is that huge networks collapse and display separation far shorter than the number of nodes they have.
4. Examples of separation ranges include our society, the WWW, and the Internet. First of all, our society, which has a network of six billion nodes, has a separation of six. The Web, which close to a billion nodes, has a separtion of nineteen. The Internet, a network of hundreds and thousands of routers, has a separation of ten.
5. Research suggests that fundamentally, as more links are added, there is a higher possibility of the distance between the nodes to collapse. The origin of the small separation can be explained as the logarithmic term presented in a mathematic formula; the logarithm shrinks the huge network and creates a small world around us.
6. I think that my connections to the society could be divided into more than 5: university, high school, elementary school, my old gymnastics club, family, etc. What is more, it can be divided even more inside those networks. For example, my university connections can be divided into my ultimate team, section mates, division friends, and etc. Personally, whether I like it or not, the connections with my bukatsudo is the strongest right now because I spend so much time with them.
