Yesterday’s puzzler was to guess the species being talked about here:

One became super efficient at gobbling up its food, doing so at a rate that was about a hundred times faster than the other. The other was slower at acquiring food, but produced about three times more progeny per generation.

The answer is…

I’m giving my “2009 Q1 award for most concise, lucid comment” to Paul Phillips for this gem:

Viewed from a thousand miles, the financial system has a incalculably large incentive to fail catastrophically as frequently as it can do so without killing the goose that lays the golden eggs.

As long as there is such a thing as “too big to fail” and trillions of dollars are available for siphoning, according to what logic can this cycle be dampened?

With his permission, I am posting an email thread between myself and Alfred Hubler.  I had contacted him on the recommendation of John Miller when Kevin and I were posting on the possibility of dampening boom-bust cycles in the financial markets through policy or other mechanisms.  Here’s what Hubler had to say:

Debbie Maier asks us on the Upcoming Topics page to address Crohn’s Disease.

The above is a self-replicating dynamic structure from a class of systems called cellular automata (click here to run the simulation).  Below is a self-replicating dynamic structure from a class of systems called “life”:

I’ve talked on here about the importance of taking seriously the notion of agency as it applies to systems other than biological.  In reading a recent Wired retrospective on what they called wrong, I was struck by feeling that their error was the same in all three cases, and that is underestimating the degree to which complex systems will defend themselves in the face of attack as if they were living, breathing organisms.

I posted earlier on emergent causality. One aspect that needs to be elaborated on is the concurrent, self-interdependent nature of emergence, or in other words the chicken and egg problem. (more…)
