Tracing the Universe Back to its Beginning

Science writer John Gribbin takes on one of physics' long standing puzzles, how general relativity, which explains the very large, and quantum theory, which explains the very small, might fit together into a single theory of everything. The number in the book's full title refers to the currently accepted age of the universe in billions of years, the figure his story builds toward.

Blending science, history and biography, Gribbin traces the researchers and ideas that led to this figure in a style that has made him one of the more widely read popular science authors. It suits general readers curious about cosmology who want the history behind the numbers rather than a maths heavy text.
