Strange Frequencies takes readers on an extraordinary narrative and historical journey to discover how people have used technology in an effort to search for our own immortality. Bebergal builds his own ghostly gadgets to reach the other side, too, and follows the path of famous inventors, engineers, seekers, and seers who attempted to answer life's ultimate mysteries. He finds that not only are technological innovations potent metaphors keeping our spiritual explorations alive, but literal tools through which to experiment the boundaries of the physical world and our own psyches.
