Question

The "Small world effect" states that the average degree of separation in an aquaintanceship graph of the whole world is 6. In other words, a path of aquaintance relation from you to any other person on earth exists with, on the average, a path length of 6 (5 intermediate persons). Experiments in delivering hard-copy letters and e-mail messages have empirically confirmed this theory.

a. What are the potential implications for e-mail traffic if the small world effect holds for computer networks?

b. What are the potential implications for epidemiology if the small world effect holds for physical contact between humans?

I'm not sure exactly what it's asking for. I'm thinking for a the e-mails could potentially take a long time to reach you or that there could be a "traffic jam", and b that a lot more people would be sick, but that people could identify whats wrong easier? Any help is appreciated this is discrete math.

Explanation / Answer

a.If small world effect holds for computer networks then an email should reach the destination atmost by 6 hops.

b.Small world effet states a graph in which most nodes are not neighbour of each other but the neighbour of any given node are likely to be neghbours of each other and most nodes can be reached to each other by minimal steps.
If it implemented for physical contact between humans, that people is know each other more but yes people will fall sick more since neighbour of one node is ikely to be neighbour of another node, so every node is connected to a large number of nodes. Transfer of disease(especially communicable disease) is very easy.
