Niels Bohr Lecture by Helge Stjernholm Kragh

Fifty Years Ago:

The Discovery of the Cosmic Microwave Background in Its Historical Context

Abstract: On 21 May 1965 the New York Times announced on its front page the discovery of the cosmic background radiation, generally seen as a turning point in the development of modern cosmology comparable to the discovery about 1930 of the expansion of the universe.

The history of the primordial microwaves is no less remarkable than the later consequences and understandable only within the larger framework of the history of cosmology since the 1930s. It is a story of missed opportunities and rival views of the universe.

The lecture will present and discuss some of the historical, philosophical and sociological problems related to the discovery.
