The slide rule, with its many variations, has been vital to mathematics and engineering since its invention in the 17th century. Interest in this field has grown dramatically and collectors can still find much material at affordable prices. Unfortunately there has been little information available except for manufacturers manuals and catalogs, making this reprint of Cajori's classic particularly valuable. Also included with this reprint of the 1910 edition is Cajori's extensive article On the History of Gunter's Scale and the Slide Rule during the 17th Century, published by the University of California in 1920, which sets forth his subsequent findings. There is also a helpful explanatory introduction by Dr. Robert K. Otnes, editor of the Journal of the Oughtred Society

This book—the sixth volume in The Great Cultural Eras of the Western World series—provides information on more than 400 individuals who created and played a role in the era's intellectual and cultural activity. The book's focus is on cultural figures—those whose inventions and discoveries contributed to the scientific revolution, those whose line of reasoning contributed to secularism, groundbreaking artists like Rembrandt, lesser known painters, and contributors to art and music. As the momentum of the Renaissance peaked in 1600, the Western World was poised to move from the Early Modern to the Modern Era. The Thirty Years War ended in 1648 and religion was no longer a cause for military conflict. Europe grew more secularized. Organized scientific research led to groundbreaking discoveries, such as the earth's magnetic field, Kepler's first two laws of motion, and the slide rule. In the arts, Baroque painting, music, and literature evolved. A new Europe was emerging. This book is a useful basic reference for students and laymen, with entries specifically designed for ready reference.

With unprecedented current coverage of the profound changes in the nature and practice of science in sixteenth- and seventeenth-century Europe, this comprehensive reference work addresses the individuals, ideas, and institutions that defined culture in the age when the modern perception of nature, of the universe, and of our place in it is said to have emerged. Covering the historiography of the period, discussions of the Scientific Revolution's impact on its contemporaneous disciplines, and in-depth analyses of the importance of historical context to major developments in the sciences, The Encyclopedia of the Scientific Revolution is an indispensible resource for students and researchers in the history and philosophy of science.
