As the world’s first and only full-scale computational language, the Wolfram Language represents a milestone in the development of programming languages that makes leading-edge computation accessible to everyone. Unique in its approach of building in vast knowledge and automation, the Wolfram Language scales from a single line of easy-to-understand interactive code to million-line production systems. This book provides an elementary introduction to the Wolfram Language and modern computational thinking. It assumes no prior knowledge of programming, and is suitable for both technical and non-technical college and middle-to-high-school students–as well as anyone with an interest in the latest technology and its practical application. Run everything in this book in any Wolfram environment on the web or your desktop.
