Supplementary Photos to the Chapters
Number preceeding each photo indicates the appropriate book chapter for it. Readers of CATCH A FALLING STAR may wish to view these supplementary photographs while reading that chapter. These numerous supplementary photos extend the forty photographs that are reproduced in the book. Family photographs may be of biographical interest to readers wishing to share the forces of my life more completely. Those of high interest for history of nucleosynthesis are mostly links from my Photo Archive website.
