"The new sixth edition of the Dictionary of minor planet names, which is the IAU’s official reference work for the field, now covers more than 17,000 named minor planets. In addition to being of practical value for identification purposes, this book provides authoritative information on the basis of the rich and colorful variety of ingenious names, from heavenly goddesses to artists, from scientists to Nobel laureates, from historical or political figures to ordinary women and men, from mountains to buildings, as well as a variety of compound terms and curiosities."

"A model to contour hydrographic data was designed to determine the depth of water. Because uf sparse and random nature of the given data, we superimposed an optimally sized grid system on the region and assigned the known data at their corresponding grid points. Thon We used the principle of minimum curvature tn derive finite difference? equations that calculated the remaining grid points. We iterated these equations until a convergence criterion of 0.01 over the whole grid was reached; this gave us a grid of values to contour. To insure corvergent.e of the grid before round-off error swamped the routine, we put the grid through an initializenq routine. The Geographical Information System is used to develop a powerful set of tools for concerting and displaying hydrographic data from the real world."
