Ah, thank you.Can anyone give me a layperson pronunciation? I know there's one up there, but I think I've heard people say it with an "ah" at the end. seh-zur-ah Is that right?It's still surprising when this happens. It's like the new information (or fatigue) has pushed out the old information. I remember it was difficult just to do basic math when I was really tired and sleep deprived once.
