Scale Free Networks

Technical but interesting view here, we examined and experimented with the SantaFe Institute about using consumer networks to market and advertise,  To some success, but not as good as we wanted.   Hints and previous writings on this in the tags below.  Are there further capabilities to drive advantage in Barabasi's work?  This is about training, but consider an advertising angle.

Q&A: Albert-László Barabási on the diversity of networks
The author of Network Science talks about his foundational work in that field and developing resources for online learning.    By Melinda Baldwin  in Physics Today

Network science is a new and rapidly growing field, with applications ranging from protein interactions to the internet. However, the sheer breadth of areas in which network analysis might be useful presents a daunting challenge to potential textbook authors.

In Network Science (Cambridge University Press, 2016), Albert-László Barabási tackles that challenge. The result, writes reviewer Zoltán Toroczkai in the April issue of Physics Today, is “a hands-on and engaging textbook” that also makes good use of accompanying online resources, such as animations and other pedagogical tools.

Physics Today recently talked to Barabási about his pioneering contributions to network science, the challenges of writing a textbook in an interdisciplinary field, and his approach to developing online resources. ... "
