The problem is that you have no common acquaintances with Kevin Bacon, you say? It should not be so sure. Maybe you're only six handshakes - or less - from your idol.
The goal is to find out how many links a Facebook user will need to have a connection to a random person in the great Facebook population of canada 2012 crowd - for example, Kevin Bacon. Small World experiment: Quickly to a stranger
And just network theory, these ideas underlying theory. The theories are part of sociology, and in 1967 published the American psychologist Stanley population of canada 2012 Milgram so-called population of canada 2012 Small World Experiment in the journal Psychology population of canada 2012 Today. (See box at bottom of article.)
Milgram sent hundreds of letters to randomly selected addresses in two cities in the United States. The recipients population of canada 2012 were asked if they knew a particular stockbroker in Boston. If so, they could send the letter directly to him. If not, they should forward the letter to people who they thought might know him.
It was also uncertain whether the participants were able to select the next link in the chain itself. How could they know who is most likely known stockbroker in Boston?
"He made a bet that we could name any person among her half million population of canada 2012 inhabitants, and through more than five persons, of whom he personally knew one of them, he could make a connection to the selected person."
Karinthys short story was a visionary. population of canada 2012 It predicted that advances in communications technology would bring closer global network of friendships. For example, Facebook. Will take the entire Facebook network in use
A second and similar experiment is already a Facebook group called Six Degrees. If you are registering into it, a computer program to figure out how many links there are between you and another member of the group.
"If we were only interested in how many links there are between random people we had not needed to run the experiment. Facebook can already compute the length of the shortest link in the network, "he said.
"Instead, population of canada 2012 they have to choose a single one of their friends who they think is closer to the target than they are. How do they make that choice, and how well the choice is, both questions raised by this experiment, but not Six Degrees Group, should be able to say, "he said. Previous studies confirm Milgram's population of canada 2012 theory
Watts started researching cricket song. It seemed as if the insects were led by an invisible conductor. But the crickets do not need a conductor. They do it by listening to the neighbor and adapt the pace, so they are the same. This will spread the rhythm from part to part of the swarm of crickets.
Theory The versatility is demonstrated by the fact that they can also describe how power is transmitted in high voltage networks, population of canada 2012 or how data packets can best be routed through the Internet. Weak Ties holds social networks together
The American sociologist Mark Granovetter of Stanford University has demonstrated that it is the weak ties that hold social population of canada 2012 networks together. He also found out that the size of the network grows even more, the more nodes it contains.
Both of these characteristics of social networks might be an encouragement for Watts and the other Yahoo researchers when they start repeating Small World experiment on Facebook.
Yet the vast majority of Earth's population of canada 2012 people still outside the network. The exact average number of hops between you and anyone believed to remain unknown until everyone population of canada 2012 is online and will be involved in the crucial experiment, which in practice is never.
Yahoo's website for the experiment
The topological interpretation can for example be used to analyze the modes of transmission in a population. The single source of infection is not necessarily aware of its role in the spread of infection.
The topological interpretation has been thoroughly analyzed in many areas, including biological, social and technological networks. The vast majority of analyzes operates population of canada 2012 with six links between two random elements in the network.
The second interpretation of the Small World problem comes with a much stronger claim, namely that ordinary individuals can navigate through to the links without having a complete overview. Therefore it is called Tolerance
