"Each one is a container for some rod logic and some memory," Napier 
said. "When one particle encounters another either in vivo or in vitro, they dock and seem to exchange data for a few moments. Most 
of the time they disengage and drift apart. Sometimes they stay 
docked for a while, and computation takes place—we can tell because the 
rod logic throws off heat. Then they disconnect. Sometimes both particles go 
their separate ways, sometimes one of them goes dead. But one of them always 
keeps going."
