Now in paperback. A journey through the attempts artists, scientists, and tinkerers have made to imagine and communicate with the otherworldly using various technologies, from cameras to radiowaves.

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.

Peter takes the reader alongside as he explores:

the legend of the golem and the strange history of automata;

a photographer who is trying to capture the physical manifestation of spirits;

a homemaker who has recorded voicemails from the dead;

a stage magician who combines magic and technology to alter his audience's consciousness;

and more.
