I will be on sabbatical next school year at Virginia Tech. My usual e-mail will remain current.
I now have the copyright back for my textbook, The Geometric Viewpoint: A Survey of Geometries, formerly published by Addison Wesley. I encourage people to download it for free to 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.) I hope to rewrite the text during my next sabbatical. Professors adopting my text can get a pdf version of the answers by contacting me. I would appreciate knowing who has adopted my text.
The link Summer Research will take you to the description of the Mathematics Department's summer program and application form. Click on North Central to go to the section's home page. Click on MAA to go to the national organization's home page.
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. The link for Fr. Magnus' web site will show some of the wonderful polyhedra he has built. There are two links for information about careers in mathematics. At the end of this page are links for some pictures.

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.
