The success of nineteenth-century physics laid the foundation for quantum theory and relativity in the twentieth. Robert D. Purrington is a professor of physics at Tulane University and coauthor of Frame of the Universe.

Durham and Purrington approach the history of the universe by exploring the frontiers of physics, while maintaining a long-standing interest in astronomy and cosmology.

A unique aspect of this book is the emphasis on the way Hooke provided Newton with the key to understanding planetary dynamics, paving the way for the discoveries that made Newton one of the greatest scientists of all time.

This book instead focuses on how the theoretical discoveries came about, when and where they were published, and how they became accepted as part of the scientific canon.
