[See also the Books page for The Universe in Zero Words, published by Princeton University Press, a history of 24 great equations in mathematics and science.]

My academic training was in mathematics, so it is not surprising that many of my popular articles are about mathematics. Even the articles I write about other sciences (physics, earth science, planetary science, etc.) often have a little bit of “stealth math” in them. That is a phrase coined by K.C. Cole, a longtime science writer for the *Los Angeles Times*, who loved writing about mathematics but often found that her readers would appreciate math better if they didn’t *realize* it was mathematics!

This page, however, links to my articles that aren’t “stealth math” but overt mathematics. Because there are a lot of them, I’ll split them into categories. Follow the links below to:

- Geometry and Topology
- Applied Mathematics
