Many books I've read recently deal with advanced, yet ancient technology. Anomalous finds such as the famous Antikythera device (pictured at left) have challenged established history-of-science timelines. Here are some of the books we'll be discussing soon:
"Technology of the Gods", by David H. Childress, Adventures Unlimited Press, 2000. "Forbidden Archeology", by Cremo and Thompson, Torchlight Publications, 1993; 14th printing 2011. "The Giza Power Plant," by Christopher Dunn, Bear and Co., 1998. "Lost Technologies of Ancient Egypt," by Christopher Dunn, Bear and Co., 2010.
