Contemplating the end of the world, math, mystery and other things

I suffer from eschatological obsession. That is, I spend lots of time brooding about ends. So the cover of the September Scientific American —which reads simply "the end."—made me all shivery, like when I hear the spooky sitar opening of The Doors' apocalyptic rock poem "The End." (I'm never more Freudian than when I hear Morrison's Oedipal yowl.)

Some issue highlights: Tom Kirkwood's article on why we shouldn't expect the end of death soon (someone send this to Ray Kurzweil); Arpad Vass's description of a corpse's busy afterlife (which reminds me of one of my favorite novels, Jim Crace's Being Dead , Picador 2001); George Musser's riff on whether time can end (which would mean the end of ends—like, grok that, dude!).
