"The purpose of this compilation is to provide a ready means of identifying the named nondimensional numbers that are used in the various technical areas. The compilation probably contains most of tile named nondimensional numbers that might be encountered. It also contains a few unnamed numbers that seem to be frequently used in certain felds. No claim to completeness is made, since the compilation represents mainly the "private collection" of the author rather than the result of an extensive and systematic search of the technical literature."--Page 1.
