註釋A selection of pioneering papers by American cosmologist Edwin Hubble (1889-1953), presented with historical background and extensive annotations by Norriss S. Hetherington. Included are Hubble's initial investigation of faint nebulae, his discovery of Cepheids in the nebulae, the use of these stars to determine distances for the first time to objects outside our galaxy, his demonstration of the expansion of the universe, and his mature reflections on cosmology and the nature of scientific investigation.
