## Foldit

Has anyone played Foldit, the protein-folding game that is designed to advance the science? This Wired article makes it sound like Ender’s Game meets biochemistry! Sounds like the Poehlman kid is the protein-folding equivalent of Stephen Wiltshire. I love the crowdsourcing, the meta-evolutionary algorithm of it (to find the savants), and the implications for science.…

## Newcomb's Meta-Paradox

Tweeter, Claus Metzner (@cmetzner) alerted me to this cool area of study with this paper.

Suppose you meet a Wise being (W) who tells you it has put $1,000 in box A, and either $1 million or nothing in box B. This being tells you to either take the contents of box B only, or to take the contents of both A and B. Suppose further that the being had put the $1 million in box B only if a prediction algorithm designed by the being had said that you would take only B. If the algorithm had predicted you would take both boxes, then the being put nothing in box B. Presume that due to determinism, there exists a perfectly accurate prediction algorithm. Assuming W uses that algorithm, what choice should you make?…

## Encoding Life's Complexity

Will Wright’s demo of Spore illustrates some key concepts of complex systems, including the notion of simple rules generating complex behaviors, and also the power of recursively applied (i.e. fractal) computation at different levels. Living systems leverage these same principles.…

## Parrondo's Paradox and Poker

Parrondo’s paradox is the well-known counterintuitive situation where individually losing strategies or deleterious effects can combine to win…. Over the past ten years, a number of authors have pointed to the generality of Parrondian behavior, and many examples ranging from physics to population genetics have been reported. In its most general form, Parrondo’s paradox can occur where there is a nonlinear interaction of random behavior with an asymmetry, and can be mathematically understood in terms of a convex linear combination.
