I once described how iconic Prof. Richard Feynman is (see Feynman and Statistics). At last, these lectures are publicly viewable through Project Tuva. Not knowing what this Project Tuva is, naturally I checked wikipedia, from which I found it’s related WorldWide Telescope which runs on Silverlight by Microsoft Research. Virtual Observatory is one of the most sought projects in astronomy. Several postings related to Google Sky are available here but not much about WorldWide Telescope. I attribute its lack of discussion in the slog to its late debut. Also, the fact that renown astronomers are working on site for the WorldWide Telescope has pressured me. Please, visit worldwidetelescope.org.
