On the Connexion of the Physical Sciences

"On the Connexion of the Physical Sciences" by Mary Somerville is a scientific publication written in the mid-19th century. The work explores the interrelationship between various physical sciences, particularly focusing on the principles of astronomy and gravitation. It delves into how these scientific concepts are interconnected, emphasizing the unity and harmony present in natural laws. At the start of the text, Somerville introduces her overarching theme: the pursuit of knowledge in science as a form of elevated contemplation. She argues that understanding the physical world, especially through the lens of astronomy, reveals the grandeur of the universe and the laws governing it, which reflect a higher order. The opening portions lay the groundwork for detailed discussions on celestial mechanics, gravitation, and the mathematical theories that underpin the motions of heavenly bodies, thereby emphasizing the beauty and complexity of the physical sciences.
