Steve Carlson Professor of Mathematics Rose-Hulman Institute of Technology Terre Haute, Indiana E-MAIL:  carlson@rose-hulman.edu I have been teaching at Rose-Hulman Institute of Technology -- a private college specializing in engineering, science, and mathematics -- since 1989. I received a Bachelor of Arts degree in mathematics and physics and Master of Arts and Doctor of Philosophy degrees in mathematics from the University of Kansas.  In addition to K.U. and Rose-Hulman, I have held teaching positions at Baylor University, Grinnell College, the University of North Dakota, and -- during a 1996-97 sabbatical leave -- Indiana University.  During the 2004-05 year I again took a sabbatical leave working as the Visiting Mathematician for the Mathematical Association of America in Washington, DC.
