In A Brief History of Time Stephen Hawking described our attempts to formulate the physical laws of the universe. In this work, Nobel Laureate, Gell-Mann, argues that this is only the beginning of what we need to know about our world and ourselves. What if we know those laws? What next? Seeking a unified theory of all matter, whether it is the structure of galaxies or the moment of creative thought in the human mind, this book defines the underlying unity in such diverse fields as linguistics, archaeology, economics and politics.
