This page covers a few of my scientific accomplishments. Over the course of my scientific career I was involved in a host of fascinating and important projects.
More often that not the chasm that seems to exist between the scientist and the nonscientist is one of language. But it is possible to communicate across such boundaries. It was with that in mind that I took on the task of writing what became a very successful introductory astronomy textbook, 21st Century Astronomy.
