A Brief History of Time by Stephen Hawking (Paperback)

First published in 1988, A Brief History of Time sets out to explain the big questions of cosmology to readers with no mathematics beyond school level. Stephen Hawking covers how ideas of space and time changed from Aristotle to Einstein, the expanding universe, the big bang, black holes, the arrow of time and the search for a unified theory. The book uses only one equation, and its diagrams and plain explanations have made it one of the most widely read science books of the last century.
