Welcome to my website and to my ambitious re-write that is in progress. I reside in the Temecula Valley in Southern California where one can still see the Milky Way on a summer evening, and I'd like to keep it that way. My website provides a variety of animations, illustrations, and presentations I've created to teach about light pollution, astronomy, and general science. I can be reached via my blog Bright Stars Wildomar, which gets updated more often than this site. I'm also a member of the Temecula Valley Astronomers and a contributor to Skeptical Science. (jg)
I frequently present to schools and general audiences. Most of my presentations can be viewed here, though they are not formatted for every display device and may lack text narration. All my illustrations and animations are orginal, but the content usually draws from the primary scientific literature.
Here I include illustrations, animations, presentations, and interactive graphs I've created to share the science of climatology with general audiences. (By the way, the planet is warming at an unprecedented rate and humanity is causing it -- just so people know where I stand on this.)
Have you ever wanted to know everything about the natural world? Not only must one assemble key developments in geology, climate, and evolution, but it helps to see relationships. My geological timeline is my attempt to collect and interconnect key events in Earth's history. It will be a life-time work-in-progress
Riverside county is experiencing rapid growth that threatens to pollute the night sky with a glow of man-made light. Most light pollution is an unnecessary by-product of poorly designed light fixtures that also waste energy, create visibility hazards, and can be considered intrusive. Failure to design for the effect of Riverside County's growth on the night time environment will affect communities, observatories, parks, and wilderness areas. While many of the effects are merely unpleasant or nuisances, some have safety ramifications and threaten scientific research at Palomar Observatory.
Ecology and Botony:
Here I started a plant identification guide for Southern California plants, plus other plant and nature projects.
