So I signed the contract last week for “Winding Around”, my book based on the course I taught in the MASS geometry/topology track last year. It will appear in the American Mathematical Society’s *Student Mathematical Library* series, and the manuscript is due to be delivered to them on April 1st – I leave it to you whether or not you think this is an auspicious day! The book centers around the notion of “winding number” (hence “Winding Around”) and uses that as a peg on which to hang a variety of topics in geometry, topology and analysis — finishing up, in the final chapter, with the Bott periodicity theorem considered as one possible high-dimensional generalization of the winding number notion.

The intended audience is an undergraduate one (there was skepticism from some of the AMS readers about this, but I told them the MASS students made it through okay!) and the tone is, I hope, entertaining and discursive. As I say in the introduction, “*Winding around* is a description of the book’s methodology as well as of its subject-matter.”
