When my friend Cristina speaks, I listen. Cristina is both a scientist and an artist, and throughout the years she guided me in learning about the world of science and the world of art. Years ago, she explained to me how the Inca irrigated their terraces in Machu Picchu and Tipon, and later she exposed me to the forgotten artisanal Romanian culture. A few months ago she told me about her experience in Greece, where she stood inside the ruins of Mycene (second millennium BCE) and felt the air and the ground vibrate with sound. Cristina knew she was experiencing pressure waves vibrating in the air around her and inside her body, but still, the experience was eerie.
