Ghost Stories
Ghosts, ghouls, shades from the past...in this episode of Radiolab, real-life people try to pin down, and make peace with, mysterious figures that haunt them, prod them, and fade out of existence. One man finds a way to put the beatdown on his personal bogey man, a dead monk spurs a king to build a perfect prayer machine, an unknown face launches a thousand dummies (actually, a whole lot more than that), and a skeptic goes on a one-way journey to find out whether spirits exist.
