This book explores the development of modern science and the shift from a closed, geocentric worldview to an infinite, heliocentric one. The author, Alexander Koyré, examines the philosophical and scientific ideas that led to this shift, including the works of Copernicus, Kepler, and Galileo, and how their discoveries and theories challenged traditional beliefs about the nature of the universe. The book also discusses the impact of these ideas on religious and cultural attitudes, as well as their ongoing relevance to contemporary scientific thought.
