Chapter 2 



BoNDi, Herman. Cosmology (Cambridge University Press, 1954). 

 The speculations of one of the members of the team of Hoyle, 

 Lyttle, Bondi, and Gold, a team that has made an important con- 

 tribution to cosmology. 



Bruno, G. See Singer in Chap. 1. 



BuFFON, G. L. L. See Gamow, The Biography of the Earth, below. 



Finlay-Freundlich, E. Cosviology (International Encyclopedia of 

 Unified Science. University of Chicago Press, 1951). An impor- 

 tant statement for the advanced student. Gives some support to 

 the idea of an infinite universe with a hierarchic structure, such 

 as was suggested by Lambert and much earlier in a general sense 

 by Bruno. 



Gamow, George. Biography of the Earth (Mentor Books, 1948) 

 and also The Birth and Death of the Sun (Mentor Books). In 

 these two books Gamow, one of the best and most entertaining 

 expositors of science, tells the story of the earth's origin and of 

 the wide universe of stars in which our sun is but a small incon- 

 spicuous body. Newer theories, such as that of Whipple, were not 

 available at the time of Gamow's writing, but both books are 

 well worthwhile anyway. See also Gamow's One Two Three 

 . . . Infinity (Viking Press, 1947) for more recent theories. 



Gamow, George. The Creation of the Universe (Viking Press, 

 1952). The interesting and well-told story of the origin of the 

 galaxies as the proponents of the theory of the expanding uni- 

 verse see it. 



HoYLE, Fred. The Nature of the Universe (Harper, 1951; Mentor 

 Books). Here is a most fascinating speculation concerning the 

 nature of the cosmos. Hoyle and his colleagues, Lyttle, Bondi, 

 and Gold, have boldly attacked every angle of the problem with 

 all the physical and mathematical weapons available to them. 



Hubble, Edwin. "The Problem of the Expanding Universe," 

 American Scientist, Vol. 30 (1942). The discovery of the "red 

 shift" in the spectra of distant galaxies, a discovery which pre- 

 ceded the idea of the expanding universe, is here discussed; 

 Hubble cautions against assuming that the red shift necessarily 

 means expansion. 



Jeans, Sir James. Physics and Philosophy (Macmillan, 1943). A 

 great book. 



Johnson, Martin. Time, Knowledge and Nebulae (Dover, 1947). 

 The very difficult concepts of E. A. Milne (kinematical rela- 

 tivity) and others are reviewed.
