Exploration geologist, author, and artist-adventurer Charles Lindsay delves into earth’s geologic and cultural pasts. Along the way, he investigates inter-species communication, music, memory, and the promise of Artificial Intelligence. His traveling “laboratory,” FIELD STATION 4, re-purposes scientific equipment salvaged from the aerospace, biotech, and military sectors to probe biologic specimens, ancient artifacts, and the rough edges of human perception. Lindsay directs SETI AIR, the artists-in-residence program at the SETI Institute (Search for Extra Terrestrial Intelligence) in Mountain View, California. His latest book is Recipes for the Mind, published by Terra Nova/MIT Press.
