Counterexamples in Topology
During my first years at St. Olaf I sought and received NSF support for a program of undergraduate
researchat that time a rarity in mathematicsto provide a base for St. Olaf graduates to enter strong
graduate schools in the mathematical sciences. Since my teaching
at that time focused on analysis and topology, it was natural to select research topics that grew out of those interests. Counterexamples
in Topology, coauthored with St. Olaf colleague J. Arthur Seebach,
Jr. and supported by a cast of undergraduate mathematics majors,
emerged from summer undergraduate projects in the late 1960's to
become the standard reference in the field. It was revised and republished twice since 1970, most recently in 1995.
Telegraphic Reviews
In 1970, in collaboration with the late J. Arthur
Seebach, Jr., I began what turned into a twentytwo year stint as
Telegraphic Reviews editor of the American Mathematical Monthly, the
major journal of the Mathematical Association of America (MAA). Faculty
from St. Olaf, Carleton, and Macalester Colleges wrote brief reviews
of approximately 1000 mathematics books annually to help college mathematicians and librarians select volumes of greatest value and interest. The sustained commitment of St. Olaf faculty as a center of editing
and reviewing for undergraduate mathematics contributed greatly
to the development of the department and to unparalleled strength in the mathematics section of the St. Olaf College
Library.
This threecollege Telegraphic Reviews system continued throughout the 1990s under the leadership of my
St. Olaf colleague Arnold Ostebee until time and technology was ripe for a fully online system,
MAA Reviews, that is now part
of the Mathematical Sciences Digital Library.


Mathematics Today & Tomorrow
In the 1970's I served as the first Mathematics Editor
for Science Newsa weekly newsmagazine of scienceand also wrote annual articles on advances in mathematics for the Encyclopaedia
Britannica. During this same period I also edited a volume of
popular essays entitled Mathematics Today,one of the first
mathematics books to be reviewed in The New Yorker. A few years later this volume was republished in paperback, about the same time as a more speculative sequel, Mathematics Tomorrow, appeared.
These
experiences led to a course in Science Writing that I cotaught
for ten years with my wife Mary, a member of the St. Olaf English
Department. The focus of this course, like that of my own writing,
was to explain technical subjects to an attentive general audience.
Mathematics Magazine
For the five years from 1976 to 1980 Arthur Seebach and I collaborated
on yet another project: editing Mathematics Magazine, a
bimonthly magazine of undergraduate mathematics published by the Mathematical Association of America (MAA). Mathematics Magazine publishes feature articles, short notes, problems for undergraduates (followed by submitted solutions to previous problems), and a section of latebreaking news and letters. In 1976 Mathematics Magazine provided the first news report for mathematics faculty of the computeraided solution to the famous Four Color Problem (v. 49, pp. 219222).
Twenty years later, in 19962000, Mathematics
Magazine returned to St. Olaf under the editorship of Paul Zorn who, in 2004, became chair of the St. Olaf College Department of Mathematics, Statistics and Computer Science.
