yup, I'm still writing, rewriting, thinking and re-thinking. I hate this stage of work; you realize that you're wasting time being critical of yourself but you still can't be satisfied with what little has (or how much has not) apparently been accomplished. Anyway, I'm just going back through my introduction (again) and seeing some interesting things. Like the fact that when I sum up what it is I study, the following chain of uber-dry terms appears: "...spatial and temporal scales of steady-state critical-taper orogenic evolution". My undergraduates would experience the instantaneous onset of unconsciousness if I ever said that phrase to them (either by fear or boredom, I'm not sure which). But yeah, I guess, that's more or less what I study in a nutshell.
