|  Scale free.....................
It is interesting that through the talk of networks mathematicians and physicists can be related to them. The theories of Erdos and Renyi are very interesting but they only apply to fixed networks and not ones that grow. To clarify things the definition of a scale free network:
A scale free network is a natural consequence of the ever-expanding nature of real networks. Simply put it starts off as two nodes connected to each other. As new nodes begin to link to the existing nodes they will only link to the nodes with more connections. Through this as nodes get more connections they become hubs.
The Web is a prefect example of a scale free network. There are several hubs like CNN (mentioned in the readings) or even perhaps public forums. I think in our daily lives there are certain people that are hubs, people that are well connected to other people. And of course depending the connections of that person other people may want to get to know him just because of their connections.
