Howard Eves celebrated his eightieth birthday in 1991. To honor that occasion, the University of Central Florida sponsored a conference that focused on the life-long interests of this prominent American mathematician namely, the history of mathematics, the teaching of mathematics, and geometry. Howard is well-known for his contributions to all three areas. He is author of one of the best known books that has ever been writen on the history of mathematics, has a long association with the Mathematical Association of America, and has published extensive research in geometry. The conference was unique. Conference participants included pre-college mathematics teachers, community college and university teachers, and research mathematicians. Papers were delivered in sessions devoted to the classroom teacher, to the history of mathematics,and to pedagogical and research interests in geometry. Many lectures combined these subjects. This book presents some of those lectures. anyone involved with teaching or producing mathematics can find something in this volume that will be interesting to them. Some of these papers are speciically for the classroom teacher. They discuss a use of technology, or the organization of a class for some specific purpose. Other articles will provide teachers with examples of mathematical problems or historical episodes that can be used as part of a mathematics class. Still other papers deal with the philosophy of mathematics education. There are articles in this volume that present new insights into some of the history of mathematics, and there are other articles that deal with some new results in geometry. This is really the legacy of Howard Eves. He has been both a mentor for teachers at every level, and a colleague of research mathematicians. And so some part of this volume wil be appropriate for anyone interested in mathematics.
