Spook: Science Tackles the Afterlife -- Mary Roach
Mary Roach writes about our search for the afterlife. She talks about spiritualism, a scientist who massacred mice in an attempt to weigh their souls (a different scientist originally tried something similar (weigh-ins at the moment of death, not massacres) on people dying of consumption but, go figure, the public objected). She goes to India to find out about reincarnation, to England to go to a weekend seminar about being a medium, gets zapped with electromagnetic rays to induce a haunting via vibrating eyeball. There was a even a chapter about ectoplasm.
It was awesome.
Do I really need to say anything else?
