For almost 40 years, Chet Raymo walked a one-mile path from his house to the college where he taught physics, chronicling the universe by observing every detail of his route with a scientist's curiosity, a historian's respect for the past, and a child's capacity for wonder.
With each step, the landscape he traversed became richer, suggesting ever deeper aspects of astronomy, history, biology, and literature, and making the path universal in scope. His insights inspire us to turn our local paths into portals to greater understanding of our interconnectedness with nature and history.
