Hello! A Wyoming child, I love words and the natural world. In mid career as an astrophysicist, I study galaxy evolution and I know a fair bit about spectroscopy. This blog is an outlet for me to explore a broader range of topics than the merely technical. I discuss science, writing, music, critical thinking, and I slip in updates on Ace Carroway, adventurer extraordinaire.


There are book-related sites at which you can “follow” me, if you’d like.

Occasional “sales” and “deals” might pop up now and then at these places.

You can contact me with the following form. It just sends me an email – nothing fancy.

Comment “Sign me up,” if you’d like to be on my email buddy list. I give away books to people on that list, but I only send an email at new release time. That works out to twice a year or so.


It seems like I ought to do something with these links.
