Back when I was in high school, I read Dan Brown's Angels and Demons. Although, as with all of Dan Brown's plots, it focuses on the conspiracies withing Christian hierarchy and doctrine, the specific plot centered around a container of antimatter. This, however, has not been an achievable feat. Only recently have scientists been able to keep antimatter particles around for 1000 seconds (specifically antihydrogen). Servia sent me an article about it.
Update on Infinite Summer: Maybe I have poor taste, but I am still not a fan of Infinite Jest after reading another 2%. Although the language is erudite and interesting and the images are eccentric, much of what gestures toward humor relies upon a type of gross imagery that gets rather boring and repetitive. When I heard about the book, I was expecting something like an absurdest-humor non-fantasy version of Jonathan Strange and Mr. Norrell with a plethora of footnotes and backstory. I'm going to stick with it for the moment.
