# gst: transitions by coupled instabilities

AA << present an experimental study of quasiperiodic transitions between a highly ordered square-lattice pattern and a disordered, defect-riddled state, in a circular Faraday system. (They)  show that the transition is driven initially by a long-wave amplitude modulation instability, which excites the oscillatory transition phase instability, leading to the formation of dislocations in the Faraday lattice. The appearance of dislocations dampens amplitude modulations, which prevents further defects from being created and allows the system to relax back to its ordered state. The process then repeats itself in a quasiperiodic manner. >>

# game: apropos of perpetual hack, to bypass 'lizard' brains with a Tit-for-Tat approach

<< In (..) lizard brain, (..) "cheating" was really just "retaliation." >>

<< Where do we go from here?

Is there a way to break this cycle? >>

<<  For no matter how viscerally satisfying and rational it may appear to operate in a never-ending tit-for-tat spiral, in the long run, cooperation pays >>
