now as a fun-type book, if you enjoyed the "calvinball" in the "calvin and hobbes," you'll love half-ball, and for fans of "deep thought," delillo's "space brain" provides nearly un-endurable humour (oh, wait, space brain's changed it's mind again. . .). the only way in which i'd fault delillo is that he (as many others have done/continue to do) is under the impression that mathematicians desire to win a nobel prize, but the truth is, not-just-a-few mathematicians see the nobel as a cute prize that pales in comparison to the fields medal. other than this (annoying) hindrence, ratner's star is a truly exceptional book. if you want lighter reading, go with "white noise," but ratner's star is most definitely its equal, and in some ways (that are directly related to how much the book demands of the reader and how much work the reader is willing to put into the book-as-art aspects (i.e. going after meanings not plainly displayed on the surface)) i think it exceeds all of the delillo i've read excepting underworld. basically, read this book, it'll make you're life better.
oh, that "typewriters?" things? that's because the book has a remarkable futuristic feel and does an exceptional job of transporting the reader to a pi-in-the-sky/ivory tower research facility, but there are constant mentions of typewriters that do a pretty good job of breaking the flow, but they have the effect of endearing the work rather than trivializing it.
