Summary
Frigyes Karinthy was the first person to give the perspective that "people are linked by at most five links" and this lead to the concept known as "six degrees of separation" today. In 1967, Stanley Milgram set out an experiment to find out the distance between any two people in the USA and came to the result that people are separated by 5.5 people. Through this experiment he gave out the message that "our world is small because society is a very dense web" and that the social links among people are quite tight.
To find out how many degrees are between webs, Barabasi worked with Reka Albert and Hawoong Jeong to reach the answer that any document is on average only nineteen clicks away from any other.
Personal Reaction
It is surprising to know that the medium between any two person are only six people. Although there could be exceptions because Milgram based the result only on 42 cases, the idea of finding out the distance between two strangers is very interesting. It is easier to think that the medium between webs are nineteen because every web sites has numerous and various links to other sites.

I see we've quoted the same lines from Barbasi!!
Taketei, thank you. Are you familiar with the concepts of ying and yang? What reaction do you think ancient Chinese philosophers would have to Barabasi?
