My
rewritten
textbook, ** Thinking Geometrically: A Survey of Geometries**,
is now available electronically from the Mathematical Association of America.
Here is a link:
Thinking Geometrically. The hard copy version is at the printers and so
should be out some time in August. 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.

Now that the new text is published,
in agreement with the MAA, I am removing the old version ** The
Geometric Viewpoint: A Survey of Geometries**. I
hope that those who used the old text found it valuable and will find the new
one even better.

Here are links of videos of change ringing with three bells and with four bells.

The link Summer Research will take you to the description of the Mathematics Department's summer program and an old application form.

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.
