Favorite Parts of Heavy Time by C.J. Cherryh and Thoughts on it.
P. 213 "...- It was the way the deep-spacer had said, the one they'd gotten in to talk to the class back then: You live on wave-fronts. You live on a station, you ride the local wave - the time you know. You go somewhere else, it's a different wave. Maybe a whole set of waves, coming fromd different places, different times. There's an information wave. There's fads. There's goods. There's ideas. They propagate at different rates." Poor Dek, he's a little lost still (or maybe a lot) and still trying to find his feet.
