Among his extraordinary mathematical and philosophical achievements Gottfried Wilhelm Leibniz (1646 1716) invented binary arithmetic the representational basis for todays world of digital computing and communications. This book will be the first to make a selection of his writings available in English. Strickland and Lewis provide an accessible introduction to Leibniz through some twenty mostly unpublished manuscripts dealing with binary notation algorithms for binary arithmetic and related topics. The book includes an introduction analyzing the history of the binary system and Leibnizs claim to priority and short introductions to each of the chapters
