Modern cosmology in retrospect
One sees two main areas of twentieth century cosmology. Firstly there is the work of the 1920's and 1930's when the predictions of Einstein's general theory of relativity were being worked out, while observations were beginning to show the expansion of the universe. The book contains a talk by William McCrea, who was active during this time and reports on the work of cosmologists such as Eddington and Milne. The second area is the debate between the big bang and steady state cosmologies which took place in the 1950's and 1960's. The book has details of the discovery of the microwave background, and of the measurements of elemental abundances, which supported the big bang, as well as a talk by Fred Hoyle on the development of the steady state theory.
