The discovery of the expanding universe is one of the most exciting exploits in astronomy. This book explores its history, from the beginnings of modern cosmology with Einstein in 1917, through Lema's discovery of the expanding universe in 1927 and his suggestion of a Big Bang origin, to Hubble's contribution of 1929 and the subsequent years when Hubble and Humason provided the essential observations for further developing modern cosmology, and finally to Einstein's conversion to the expanding universe in 1931.

As a prelude the book traces the evolution of some of the notions of modern cosmology from the late Middle Ages up to the final acceptance of the concept of galaxies in 1925.

Written in non-technical language, with a mathematical appendix, the book will appeal to scientists, students, and anyone interested in the history of astronomy and cosmology.

Industry Reviews

'It's wonderful to have such expert guides. Though their book claims to be for the interested man, it will prove most valuable to Physics Today readers. ... Discovering the Expanding Universe is the one you should read.' Physics Today 'Based on a close reading of original papers, this book is a pleasure to read and will be welcomed not only by professional scientists but also by amateurs. The mathematics is conveniently, and fittingly, removed to a masterly appendix.' Nuncius: Journal of the History of Science
