Does quantum mechanics show a connection between the human mind and the cosmos? Are our brains tuned into a "cosmic consciousness" that pervades the universe enabling us to make our own reality? Do quantum mechanics and chaos theory provide a place for God to act in the world without violating natural laws? Many popular books make such claims and argue that key developments in twentieth-century physics, such as the uncertainty principle and the butterfly effect, support the notion that God or a universal mind acts upon material reality. The author here examines these contentions in a carefully reasoned analysis of popular theories that seek to link spirituality to physics. Throughout the book, the author alternates his discussions of popular spirituality with a survey of what the findings of twentieth-century physics actually mean. Thus he offers the reader a useful synopsis of contemporary religious ideas as well as basic but sophisticated physics presented in layperson's terms (without equations). Of particular interest in this book is the author's discussion of a new kind of deism, which proposes a God who creates a universe with many possible pathways determined by chance, but otherwise does not interfere with the physical world or the lives of humans.
