For many people the scientific concepts that build and shape our universe are impenetrable and abstract. The big bang and Einstein's theories on relativity seem so complex that an understanding of them, for the general reader, appears impossible. The acclaimed science writer Brian Clegg, in his new book 'The Reality Frame', tackles the problem head on and what emerges is a triumph in the General Science genre. Starting from basic principles, he builds a theoretical universe that captures and illuminates the forces and dynamics that shape space, time and matter. The subject is arguably one of the most difficult for a general reader to grasp and understand but this book achieves the impossible with remarkable clarity.
