Experiments will be my eighth book when it’s published in September 2026 by Princeton University Press.  The cover design is a detail of Thoreau’s 1846 bathymetric survey in which he searched for maximum depth using a graphical iteration of seven lines as with the calculus problem of finding the limit of a curve. The manuscript was submitted in July 2024, with final queries on copyedit done Feb 4, 2026.  As of yet, there are no reviews or blurbs.   The Princeton website descriptions are quoted below.

Catalog Description

“Henry David Thoreau’s Walden stands as the foundational text for the environmental movement and as a model for the practice of nature writing. In The Walden Experiments, Robert Thorson tells the story of how, after several discarded drafts of social critique, Thoreau resuscitated Walden with a sharp swerve toward science. Thorson invites us to read—or reread—Walden to discover the observations, empirical thinking, and scientific explanations supporting this canonical work of literature. Chapter by chapter, he guides us through Walden’s relevance for such contemporary scientific concerns as climate change, ecological collapse, water supply, agriculture, artificial intelligence, and technology.

Author Description

Thoreau’s first “experiment” of living deliberately took place in a one-room house at Walden Pond from 1845 to 1847. This was followed from 1851 to 1852 by a little-known second experiment of living deliberately in the midst of society as a sojourning scientist. Thorson’s account of a science-revitalized version of Walden helps us appreciate Thoreau’s masterpiece not only for its prophetic, lyrical, uplifting, witty, and timeless advice on living sustainably, but also as a historic benchmark for anchoring our modern solutions. Exploring the science that underlies Walden enhances our understanding of the deeper meanings Thoreau draws from nature.

Robert M. Thorson is professor of Earth sciences at the University of Connecticut. He is the author of Walden’s Shore: Henry David Thoreau and Nineteenth Century Science, The Boatman: Henry David Thoreau’s River Years, and The Guide to Walden Pond.”
