Ebook: A Project to Find the Fundamental Theory of Physics

Released alongside the launch of the Wolfram Physics Project, this book provides a unique opportunity to learn about a historic initiative in science right as it is happening. The Wolfram Physics Project is a bold effort to use breakthrough new ideas and the latest in physics, mathematics and computation to find the fundamental theory of physics, often viewed as the ultimate goal in all of science. Written with Stephen Wolfram's characteristic expositional flair, the book includes both an accessible introduction to the project and its background, as well as core technical documents, and breathtaking visualizations that bring to life a dramatic new understanding of how our universe works.
