Mathematics Department 1996 Newsletter

Editor's Note:  In mid or late December, every alumna and alumnus of the
mathematics department should have received a hard copy of this newsletter via the
US Mail.   If you did not receive your copy, please send your correct mailing
address to the alumni office.

CHAIRPERSON'S MESSAGE

As I reviewed the past newsletters to prepare this edition, I realized that this is 
the 10th Department of Mathematics Newsletter.  This year, we decided to move
its publication date to the end of the fall semester, which seems to be easier than
working around summer vacation plans.  It may also be a more appropriate time of
the year because of the long tradition of Dr. Schraut s annual Christmas letter. 
This month also marks the 40th anniversary of University of Dayton Research
Institute, which has been a source of part-time jobs for many mathematics majors
over the years.  Moreover, according to William Dunham, writing in the MAA
student magazine, Math Horizons, 1996 marks three other important anniversaries
for the mathematics community:  in 1896 the Prime Number Theorem was finally
proved by Charles Jean de la Vall‚e Poussin and Jaques Hadamard; in 1796, Carl
Friedrich Gauss, who was 18 at the time, discovered the construction of a regular
17 sided polygon using only straightedge and compass; and the first calculus
textbook was published in 1696 by the Marquis de L Hospital, who was tutored by
Johann Bernoulli. We are just beginning to plan for the 18th Biennial Alumni
Seminar on Employment Opportunities in the Mathematical Sciences to be held on
the Saturday afternoon of March 8, 1997.  We would invite you to come to meet
with the students and socialize with one another.  Looking to the future, we have
invited the Ohio Section of the Mathematical Association of America to hold its
1999 spring meeting on campus, and we will try to host that meeting on the same
weekend as the 19th Biennial Alumni Seminar; the Ohio Section meetings usually
end around noon on Saturdays, so it will not conflict with the normal afternoon
timing of the Biennial Seminar.  It will give our returning alumni a chance to
participate in the Section meeting, and it will allow some visiting students to discuss
employment opportunities with our alumni.

In the 1989, 1991, and 1992 editions of this newsletter I talked about the plans for
the construction of a building to connect Sherman and Wohlleben Halls.  This on
again, off again, project has apparently been shelved.  However, long overdue
piecemeal renovation is taking place in these two science buildings thanks in part to
the entrepreneural activities of the science departments.  Our new Macintosh
computer classroom/ laboratory, which was partly paid for by a National Science
Foundation (NSF) grant to Ralph Steinlage, is a very nice facility which is now
regularly used by a variety of mathematics classes; we are now trying to have it
designated as a centrally funded laboratory so that its equipment can be kept up to
date with periodic computer upgrading.  Currently, two biology research labs, one
chemistry research lab, and one physics research lab are being renovated partly
through another NSF grant; local funds have been committed to upgrade the
infrastructure in Sherman Hall to make these renovations possible, and to prepare
the building for eventual installation of a climate control system.  Next summer, a
third NSF grant will help to install a lab to support the environmental programs in
biology and geology, and renovations of additional space in Sherman Hall
will support the physics lab component of the new science sequence for liberal arts
majors.

However, our largest challenge over the immediate future will not be related to
bricks and mortar, but to people.  At this time, all of our ranked faculty are tenured,
and our most recent hire into a tenure-track position was in 1985.  Over the next
decade about half of our current faculty will retire, and so we will be steadily
involved not only in the process of recruiting new faculty, but also in making
fundamental decisions concerning the direction the department is to take into the
next generation.

In closing, and on behalf of the entire department, I would like to extend our wishes
to you for a happy holiday season, and a successful 1997.

                                                              Tom Gantner  
     
THANKS!

We wish to acknowledge the alumni, friends and faculty who have designated gifts
for use by the Department of Mathematics.  These donations are greatly
appreciated because they go into a special fund that exists outside of our normal
operating budget, and they can often be used to leverage additional money for
needed equipment and other projects.  For example, we recently used this fund
to provide our share of the cost of a high quality, full color projection panel for
computer generated images, together with a compatible overhead projector.
According to the University Advancement Office, the following people have made
designated gifts to our department since July 1, 1995:

Paul Campbell (67)            Cheryl Cooley (93)
Paul Eloe                     John Feck (91)
Tom Gantner (62)              Joan Giardina (70)
Robert Halsted (87)           Michael Hartke (66)
Aparna Higgins                William Huster (78)
Jane Pendergast (74)          Ted Renneker (94)
Ralph Steinlage (62)          Dorothy (Como) Hafertepen (81)

In addition, corporate gifts were received from the Arthur Anderson Foundation
(for Ted Renneker), Chicago Title Trust (for Joan Giardina), Cytology Pathology
Services (for Pieter Wiersema), the Eli Lilly Foundation (for William Huster), and
Principal Mutual Life (for Paul Judd).  Finally, Paul Campbell donated about 75
new mathematics books for our departmental library.
