Just Six Numbers
The first number is N, the ratio of the electric force to the gravitational force between two protons. This is followed by the efficiency of hydrogen fusion ε and then the two cosmological parameters Ω and λ. The last two numbers are Q,the measure of inhomogeneity in the early universe and 3, the number of space dimensions.
In between the chapters on the numbers themselves there are 'Our Cosmic Habitat' chapters, leading towards Rees' favoured explanation of the fine tuning - that of multiple universes. Possibly Rees decided that the 6 numbers weren't the best way to get his ideas across, since a couple of years later he wrote a whole book with the same title as these intermediate chapters.
