Writings and Presentations This web page holds my presentations about astronomy and scientific visualization for a range of audiences. Some of these presentations were given to the general public, some were for teachers, and some were for a mixture of scientists and staff here at STScI. I have posted the slides of several talks, but only have one write-up available. If only I had more time ...
