This arises from issues I encountered in 2007. From September 2005 to the end of May 2007 I was looking for the base of a logarithm that would connect the rate of English lexical growth, about 3.39% per decade to the rate of divergence measured by Morris Swadesh for related Indo-European languages, which he found to be less than 14% per thousand years. I was looking for a number, but after many spreadsheets and failed guesses found that a network’s mean path length (mu, say) worked as the base of the logarithm. (I wrote a paper in early 2008 about this, on arxiv.)

I noticed this peculiarity about Clog (n) where n is the number of nodes in the network, and C is the clustering coefficient. From one perspective, if there are n nodes, then log (n) = k is the number of degrees of freedom in the network (or ensemble) relative to the mean path length mu. But at the same time, log (n) = k could also represent k time periods occurring for a set of nodes equal in number to the mean path length mu. So which is it? Is k the degrees of freedom for an ensemble? Or does k represent the length of time for a single cluster of mu nodes? Is this an irrelevant mathematical curiosity? Or, is there some connection between k as degrees of freedom for n nodes relative to mu and the way that time works? Why are the number of degrees of freedom for n nodes equivalent to the degrees of freedom relative to a single cluster of mu nodes over k periods of time. For example, does this imply that an event that occurs for an entire ensemble can in some way be emulated by an event repeated over k time periods for mu nodes? Perhaps it is nothing But it seems that J. Willard Gibbs in his Elementary Principles of Statistical Mechanics used a kind of variation of this when he calculated the statistical distribution of multiple copies of the same ensemble. Do these mathematical aspects indicates something about the nature of time, that a period of time for mu nodes can correspond to an event at a point of time for an entire ensemble? Does that seem to echo Minkowski’s notion of space time?
