I rewrote my textbook, The Geometric Viewpoint: A Survey of Geometries, formerly published by Addison Wesley, during my recent sabbatical. I have submitted the rewritten book to the Mathematical Association of America for possible publication. I have rewritten many of the old problems and added many new ones. In addition, I have added two new chapters on differential geometry and discrete geometry. Instructors interested in testing this new version can contact me.
At least for the meantime, people may still download the old version for free use in geometry classes. Click on this link to go to the pdf files of the somewhat modified text. (I have corrected the errors I know and I have covered up the material, mostly figures, for which I no longer have copyright permission.) Professors adopting this old version can get a pdf version of the answers by contacting me. I would appreciate knowing who has adopted my text.
Here are links of videos of change ringing with three bells and with four bells.

The link Foundations Text (below) has information on my textbook, The Foundations of Mathematics, published in March 2008 by Wiley. My Research web page has descriptions of my research interests, of articles I have written, and of projects I hope to be doing with students. You can see a version of my Curriculum vitae by clicking below. There are two links for information about careers in mathematics. At the end of this page are links for some pictures.

The first picture below shows me judging during the 2000 Donut Coloring Contest. The middle one features some of the students in my 1999 geometry class and their finished tensegrity figure. The picture on the right highlights Math Society students in 1985 making a small stellated rombicosidodecahedron out of straws and string. A more recent stellated rombicosidodecahedron is hanging in the Student Lounge of the Engel Science building at SJU, along with the tensegrity figure.
