"...[the authors] take you line-by-line through some of the key papers by Albert Einstein. It's wonderful to have such expert guides. Though their book claims to be for the interested layperson, it will prove most valuable to Physics Today readers." - Robert Kirshner, 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." - William R. Shea, Nuncius: Journal of the History of Science
The discovery of the expanding universe is one of the most exciting exploits in astronomy. This book explores its development from Einstein, through to Lemaître, Hubble and Humason. It is of interest to scientists, students, and all those interested in the history of astronomy and cosmology.
