Every now and then when I really need to get things back into perspective, I read either astronomy or geology -- popular works, that is. ATM, it's John McPhee's
Annals of the Former World -- dipping (if not striking

-- hammerheaded geologists' joke [geoke?] ) into its five books in no particular order, just here and there, finished
Rising From The Plains last night.
Five books, about rocks, almost entirely about rocks -- and he makes the formations and the rocks
sing.
