Connected: The Power of Six Degrees

A very rich documentary about the new science of network. It is built around reproducing the “Six degrees of separation” experience. The main concepts are well explained and the history of discoveries is emphasized with many examples and interviews of the researchers. I personally think the documentary is well realized and may be understood by any public.

The first part is about small worlds model and explaining why six degrees works. The second part brings the concepts of hubs and power-law degree distribution. At the end we learn more about network theory applications, in particular about cancer research.

Warning: the video is no longer available, due to right owner’s decision to remove it from vimeo.

  1. This is a extraordinary interesting documentary; however it has a major blind spot. It does not have the voices of any humanists; only Scientists. It is mono-dimensional and prescriptive; it lacks the great understanding of the human conditional gained through philosophy, history, archaeology, and literature.

    The six degree thesis is interesting; but simplistic.
