A Preliminary Dissertation on the Mechanisms of the Heavens, published in 1832 by Mary Somerville, is a foundational work in physical astronomy. It explores the laws governing celestial motions and the forces that stabilize the solar system, building on Newton's principles of motion and gravity. Somerville emphasizes the importance of experiential knowledge and the comparative analysis of terrestrial and celestial phenomena, making significant contributions to the understanding of celestial mechanics and the pursuit of scientific truth.
