Essay series

Sacred Technology

Essays on biology, light, water and sound as technology: how living systems build color, move energy and repair themselves.

Sacred Technology is a series on the Substack. The essays start from a specific organism or mechanism, such as the painted turtle that survives months without oxygen, the structure that makes a peacock’s blue, or the cavitation that drives a heartbeat, and ask what it implies about how living systems work. They are essays, not clinical guidance.
