The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

Controversial at the time, Copernicus's discoveries led to the scientific revolution, and a greater understanding of our place in the universe. An accessible, abridged edition with a new introduction. Renaissance Natural philosopher Nicolaus Copernicus's pioneering discovery of the heliocentric nature of the solar system is one of the few identifiable moments in history that define the understanding of the nature of all things. His great work was the consequence of long observation and resulted in the first stage of the Scientific Revolution by correctly positing that the earth and other planets of the solar system revolved around the sun. Not only did this promote further study to understand the place of humanity in the world and the universe, it questioned the authority of the organised Christian Church in the West to be the keeper of fundamental truths. Ultimately this would lead to the Enlightenment, and the separation of religion, government and science. The FLAME TREE Foundations series features core publications which together have shaped the cultural landscape of the modern world, with cutting-edge research distilled into pocket guides designed to be both accessible and informative.

Galileo’s Dialogue Concerning the Two Chief World Systems, published in Florence in 1632, was the most proximate cause of his being brought to trial before the Inquisition. Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

An analysis of the astronomer's pivotal sixteenth-century work traces how his challenge to beliefs about an Earth-centric solar system had a profound influence on the ways in which humanity understands itself and the universe.

Stephen Hawking explains how such great men of science as Copernicus, Galileo, Kepler, Newton and Einstein built on the discoveries of those who came before them, and how these works changed the course of science, ushering astronomy and physics out of the Middle Ages and into the modern world.

After three decades of investigation, and after traveling hundreds of thousands of miles across the globe-from Melbourne to Moscow, Boston to Beijing-Gingerich has written an utterly original book built on his experience and the remarkable insights gleaned from examining some 600 copies of De revolutionibus. He found the books owned and annotated by Galileo, Kepler and many other lesser-known astronomers whom he brings back to life, which illuminate the long, reluctant process of accepting the Sun-centered cosmos and highlight the historic tensions between science and the Catholic Church. He traced the ownership of individual copies through the hands of saints, heretics, scalawags, and bibliomaniacs. He was called as the expert witness in the theft of one copy, witnessed the dramatic auction of another, and proves conclusively that De revolutionibus was as inspirational as it was revolutionary. Part biography of a book, part scientific exploration, part bibliographic detective story, The Book Nobody Read recolors the history of cosmology and offers new appreciation of the enduring power of an extraordinary book and its ideas.
