In response to several blog posts earlier on this semester, describing our course’s broad application to biological networks (such as this one, this one, and this one) I highlight that Piers J Ingram, Michael PH Stump and Jaroslav Stark published research in 2006 demonstrating that network effects in biology are not only often poorly understood, but in their example […]

Networks in Music and Composition

Why do certain songs sound so good? Why are there simple tunes that are so catchy? How can we tell immediately that some sounds just don’t go well together? Of course, there are many factors that contribute to how music is interpreted by human ears, but much can be understood by seeing the networks behind […]

After a long night of tossing and turning last week, I decided to pick up a magazine to lull myself to sleep. Unfortunately, the only stack in my fraternity’s bathroom was of Playboys, and the obvious thing to do with those would only serve to keep me up even longer. Then I remembered what my […]

My paper topic was to look at social phenomenon through the theoretical and visual tools established by nonlinear optical theory. If interested you should read the section of the paper that gives a brief introduction about optics. The thrust of it is simply that Social Systems can be considered complex nonlinear dynamical systems and so […]

According to Heider’s social balance theoryi, individuals (nodes) in a social network tend to form relationships (+ or - edges between nodes) as follows: “for every set of three nodes, if we consider the three edges connecting them, either all three of these edges are labeled […]

Effects of Stochastic Errors on Evolutionary Behavior
Wednesday, May 2nd, 2007 11:13 pm
Written by: am494
In our brief introduction to evolutionary game theory, we defined an evolutionarily stable strategy roughly as one that tends to drive a fractionally small population of mutant strategies to extinction over time. Our setting for investigating this idea was the Hawk-Dove game played between behaviorally instinctive animals; here we saw that successive generations of […]

In a recent Wired interview[i], Fred Vogelstein asked Google CEO Eric Schmidt about the current number and future scale of Google’s data centers, to which Schmidt responds, “I think my overall description would be in the dozens. There are a few very large ones, some of which have been leaked to the press. But in […]

Interplay between Network Structure and Evolutionary Game Theory
Sunday, April 29th, 2007 9:14 pm
Written by: Benjamin Cole
The article “Scale-Free Networks Provide a Unifying Framework for the Emergence of Cooperation” by F.D. Santos and J.M. Pacheco suggests that structure of a network influences which strategies evolve within a population. Two games one of which is familiar to our class – the prisoner’s dilemma and a variation called “the snowdrift game”- are […]

Organizational Information Hierarchies: An Application of Information Cascade
Wednesday, April 25th, 2007 9:38 pm
Written by: ramuski
In what may be a politically biased article which bemoans flaws in US military intelligence organizations, Julian Sanchez argues that information cascades are a potential reason these flaws occur. He references an article on information cascades which mentions an experiment performed by economists Angela Hung and Charles Plott:
“Subjects were told that they would be picking […]
