This early work on scientific history is both expensive and hard to find in its first edition. It contains details of the developments and pivotal moments in science from the ancient Greeks to the nineteenth century. This is a fascinating work and is thoroughly recommended for anyone with an interest in the history of science. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
