Book excerpt: Digital Physics: The Physics of Information, Computation, Self-Organization and Consciousness Q&A is another digital physics book, by the Congolese-born, British-based, Ediho Lokanga. A fascinating book by the African scientist. In it, he attempts to refute several criticisms of his books and offers further arguments, insights, clarifications, and developments of the main idea of digital physics (DP), offering an original vision of reality. In this book, he presents a brief survey of the main idea discussed in his three previous books. For many years now, physicists have been trying to come up with a wonderful theory which will explain everything in the universe and make sense of everything around us. This would be a staggering and wonderful achievement. Digital physicists have added their names to the quest for a ToE from the viewpoint of computation. Physicists are busy attempting to synthesize quantum and relativistic physics. A rich variety of approaches has emerged, and these are competing against each other. The most prominent include string theory (ST), loop quantum gravity (LQG), causal sets, Euclidean gravity, topological quantum field theory (TQFT), non-commutative geometry, Penrose's twistor theory etc. Digital physicists believe they may be able to provide a possible solution to the problem of reconciling general relativity (GR) with quantum mechanics (QM) in the ongoing effort towards a possible theory of quantum gravity, which will better explain the universe in which we live. This would represent a leap forward in the human species' quest for a ToE. For students and researchers this DP Q&A can act as a starting point and an up-to-date reference for developing such a broader perspective. The Q&A presents an overview of some of the many ideas, problems and outstanding philosophical and technical issues. The book introduces the problems of quantum gravity (QG) and ToE, and raises some of the fundamental issues that researchers are trying to address. The book and Q&A are presented at an intermediate and advanced level, but use a non-technical approach so that the reader is exposed to the basic ideas as well as an overview of the results achieved so far.
