Dr. Tom Holtz’ talk on paranormal concepts in geology

Dr. Thomas Holtz of the Univ. of Maryland presents at Balticon 50 on May 30, 2016 his talk about paranormal concepts on the nature of our planet featuring discussions on Atlantis, Lemuria, the hollow Earth, sunken continents, a concave Earth, and everything made of Nummulitids (forams).

Holtz points out that many of these ideas were not crazy at the time but seemed plausible based on the science of the time. He connects all the idea with their founders and popularizers as well as with famous science fiction and fantasy literature that borrowed them.
