Notefrom the Chair
y oseph Glover

We are proud to present the first issue of the Depart-
ment of Mathematics newsletter "Little By Little", the
renamed "Walker Hall Review", still under the supevi-
sion of its able editor, Paul Ehrlich. The name change
heralds the end of the department's move into Little Hall.
All of the faculty, graduate students and staff are now
united under one roof and are focusing on making Little
Hall a more congenial place for faculty and students to
do mathematics.
The College of Liberal Arts and Sciences recognized
the teaching and advising prowess of Associate Chair for
Undergraduate Studies Kermit Sigmon with a 1995-96
CLAS Teaching Award. Kermit was treated to dinner at
President John Lombardi's house and proudly displays
his photograph with the President.
Jean Larson has turned over her duties as Asso-
ciate Chair for Graduate Studies to Bernard Mair. Jean
ran the department graduate program smoothly for three
years and successfully guided many students through the
Ph.D. and Master's programs. We wish her a pleasant
sabbatical and welcome her successor Bernard.
This spring, David Wilson and Zoran Pop-Sto-
janovic were named co-directors of the Center for Ap-
plied Mathematics and are busy revitalizing the Cen-
ter. Dave, whose research interests are in image analy-
sis and automated measurements of electrocardiographic
images, is enthusiastically fostering an applied mathe-
matics consulting group within the department with a
faculty component and a graduate student component.
This is part of the continuing expansion of the depart-
ment's applied mathematics program, following its refor-
mulation of the applied master's degree program. People
interested in reading more about this can consult our
world wide web pages at http://www.math.ufl.edu, newly
reformatted by graduate student D. Aaron Brask.
We look forward to a 96-97 academic year which
promises interesting and exciting mathematics. The de-
partment algebra group will host the second UF Galois
Week October 14 through 18 with 13 invited speakers
and over 30 participants, all focusing on cutting edge
problems in inverse Galois theory. Helmut Voelklein
and Graduate Research Professor John Thompson are
supervising the preparations for this meeting. The De-
partment of Mathematics, in cooperation with the Insti-
tute for Fundamental Theory, will also sponsor an in-
ternational conference on "Moduli spaces in geometry

and physics". David Groisser and Chris Stark are
in charge of preparations for this conference. Finally, the
department will host the Southeastern Analysis meeting
(SEAM XIII) March 14-16, a conference for researchers
in differential and integral equations, complex variables,
functional analysis and operator theory. SEAM migrates
around the southeastern U.S. each year, and organizer
Scott McCullough expects over 50 participants.
Once again, it is my pleasure to thank the friends
of the Department who continue to contribute gener-
ously to the Mathematics activities at UF The Mathe-
matics Fellowship Fund exceeded the $20,000 level in
the Spring semester, and we were able to convert it to
an "endowed" fellowship fund, so it will start to generate
interest which can be used to support graduate students
in studying mathematics. Among the recent donors in
1996, I would like to thank: Charles Ostner, Laura
Rohrbaugh, Jorge Martinez, Buford B. Whitaker,
Gregory Golden, Kee Kraftchick, Virginia Lund,
Lucille Maloney, Tracy Albert, Paul McKinley, Bev-
erly Brechner, Judith Cook, P. Belinda Kim, Sarah

As you can all see by glancing at the top of this page,
the promised contest to rename the Walker Hall Review
is now history. Last spring, I presented mathematics fac-
ulty member Frank Garvan with the handsome picture
of Colonel Walker after the entries were judged by the
Chair and Steering Committee. I was pleased to even
receive an entry by e-mail from one of our graduates Pro-
fessor Debbie Levinson, see the Alumni News Column
for more on her career.

Faculty Notes
by Paul Ehrlich
The Joint Winter Mathematics Meeting of the Amer-
ican Mathematical Society and the Mathematical Asso-
ciation of America was held in Orlando during January
10 13, 1995, and also overlapped with the annual meet-
ing of the Association for Symbolic Logic. Professor Paul
Ehrlich spoke in a Special Session on Differential Geom-
etry and General Relativity on the topic of "The nonspace-
like cut locus revisited." Professor Nicolae Dinculeanu
lectured in a Session on Probability Theory on the topic of
"Stochastic integration with respect to a stochastic inte-
gral in a Banach space." Professors Douglas Cenzer of
our department and Jeffrey Remmel of U.C.S.D. orga-
nized a Special Session on Recursive and Feasible Logic.
Cenzer spoke on "Index sets for pi-0-1 classes" and UF
graduate student William Moser spoke on "Approxi-
mate inference with generic oracle" in this session. (Cen-
zer also lectured on this topic in late January at the Re-
cursion Theory meeting held in Oberwolfach, Germany.)
Professor Jed Keesling spoke in a M.A.A. Session on
Chaotic Dynamics and Fractal Geometry on "The Levy
dragon and self-similar fractals." Hardy travelers Profes-
sors Jean Larson and William Mitchell even flew from
a meeting in Oberwolfach, Germany back to Orlando to
attend the Association for Symbolic Logic meeting which
overlapped with the A.M.S. winter meeting !!
Professor Krishnaswami Alladi organized an In-
ternational Symposium on Number Theory during Jan-
uary 1 and 2, 1996, at Anna University in Madras, India,
as part of the Ramanujan birthday celebrations there.
Leading mathematicians from the United States, France,
Italy, Japan and India participated in the symposium and
gave lectures on Ramanujan's contributions to various ar-
eas of number theory. The Proceedings of the symposium
will be published as one issue of The Ramanujan Journal,
a new international journal which was mentioned in the
fall issue of the Faculty Notes column of the Walker Hall
Review, of which Alladi is Editor-in-Chief and Professor
Frank Garvan is a Coordinating Editor. On December
22, 1995, Ramanujan's 107-th birthday, Alladi gave the
Ramanujan Day Lecture entitled "Ramanujan and the
theory of partitions the past, the present, and the fu-
ture" at the M. S. Swaminathan Research Foundation in
Madras, India. In addition, he gave several lectures on
his own research and on Ramanujan's work in Madras
during December, 1995, at the Tamil Nadu Academy of
Sciences, The Indian Institute of Technology, and at the
Conference of the Association of Mathematics Teachers
of India. On January 3, 1996, Alladi gave an invited talk

entitled "Partition identities involving gaps and weights"
at the Tenth Anniversary conference of The Ramanujan
Mathematical Society in Tiruchirapalli, India. Enroute
to India, Alladi gave a talk at the West Coast Number
Theory Conference in Asilomar, California and at the Na-
tional University of Singapore. In February 1996, Alladi
gave an invited talk entitled "A theorem of Gbllnitz and
its place in the theory of partitions" at the Conference
on Combinatorial Number Theory conducted by the DI-
MACS Center in New Jersey.
In March, Marcel Dekker published the 664 page
second edition of Global Lorentzian Geometry, by Profes-
sors John Beem of the University of Missouri-Columbia,
Paul Ehrlich of our department, and Kevin Easley of
Trumann State University in Kirksville, Missouri. It
appeared as Volume 202 in the Pure and Applied Math-
ematics Series of Dekker.
Professor Joseph Glover has been named to the
editorial board of the Journal of Theoretical Probability.
Back in Gainesville from his fall semester at the In-
stitute for Advanced Study, Professor David Groisser
lectured in a Special Sesssion on Gauge Theory at the
April regional meeting of the American Mathematical
Society held at the Courant Institute on the topic of "In-
stantons and the information metric."
Professor William Hager along with Professors Don-
ald Hearn and Panagote Pardalos in Industrial and
Systems Engineering organized a Network Optimization
Conference held under the auspices of the Center for Ap-
plied Optimization during February 12-14, 1996. NSF
funding for this conference came from three different
sectors: 1/3 from mathematics, 1/3 from computer sci-
ences, and 1/3 from operations research. The conference
announcement reveals that "advances in data structures,
computer technology, and development of new algorithms
have made it possible to solve classes of network opti-
mization problems that were recently intractable. For ex-
ample, recent advances have been made in techniques re-
lated to airline scheduling, satellite communication and
transportation, and VLSI chip design." Hager was also a
participant in a Special Session in Control Theory at the
April meeting of the American Mathematical Society in
Baton Rouge, lecturing on "Sup-norm stability for control
problems with state constraints."
Professor Chat Ho attended a regional meeting of
the American Mathematical Society at the University of
Iowa held during March, lecturing in a Special Session on
Mostly Finite Geometries on the topic of "Recent results
concerning Singer groups."
Professor Neil White of our department, together
with Professors Richard Stanley of M.I.T. and Richard
Ehrenborg of Cornell University have organized the
R,:.tatet", a Conference in Honor of Gian-Carlo Rota
which is being held at M.I.T. during April 17 20, 1996.
White also lectured at this meeting on C_'oexeter ma-

It is now one hundred years since Hadamard and
de la Vallee Poussin proved the Prime Number Theorem.
Frequent visitor to our department Paul Erdos and Atle
Selberg gave an "elementary proof' of the Prime Num-
ber Theorem in 1949. Thus among many other lectures
delivered while paying his annual spring visit to our de-
partment, Professor Erdos was requested to speak in the
Number Theory Seminar on "Problems and results about
prime numbers."
Professors David Wilson and Zoran Pop-stojanovic
were named co-directors of the University of Florida Cen-
ter for Applied Mathematics in February.

The Noetherian Ring
by Chawne Kimber and Warren McGovern
Following the lead of students at such schools as Uni-
versity of Maryland and UC-Berkeley, a new organization
has been established in the UF Math department. The
Noetherian Ring is a group of graduate students in the
department which is primarily dedicated to the support
and advancement of women in the mathematics commu-
nity. Of course, participation by all members of the Math
department is encouraged. In keeping a global perspec-
tive, we plan projects which serve to enhance the quality
of the department as a whole. Here is a sample:
1. Once a month, we sponsor a speaker who gives a
relatively accessible math-related talk. This past year's
speakers and topics include: Barbara Osofsky of Rut-
gers University (How to Plan Good Mathematics Lec-
tures), Jean Larson (Remembrances ofEmmy Noether),
Beverly Brechner (Fractal Fairy Tales), Paul Erdos
(Women Mathematicians I Have Known), Paul Ehrlich
(Women Graduate Studies and the Emergence of the
American Mathematical Community), and Jan Cheah
(Toric Varieties).
2. To ease the transition into graduate student life
at the University of Florida, we have in place a Mentor
Program. Each new graduate student is matched with a
veteran graduate student who serves as a mentor. This
person is available to answer questions about require-
ments for degrees, professors, libraries, computers,... etc.
3. We aim to play an active role in the recruitment of
qualified undergraduate students to the Graduate Math-
ematics Program. To this end we have an Informal Advis-
ing Program for undergraduates. Students are encour-
aged to drop by the department to ask us any questions
they may have about the mathematics program. In this
effort to get in contact with undergraduates, we helped
the undergraduate mathematics Honor Society, Pi Mu
Epsilon, staff their table at the CLAS Majors Expo in
April and we hope to get involved in future activities of
the organization.
Dr. Jean Larson is the ever-enthusiastic advisor
for the Noetherian Ring and the present officers of
the Ring are Chawne Kimber (President), Amy Van-
derbilt (Vice President), Warren McGovern (Secre-

tary), and Mindy Herzog (Treasurer). We are always
looking for new projects, so feel free to contact us at
nring@math.ufl.edu and visit our home page on the World
Wide Web: http://www.math.ufl.edu.

Alumni of the 1950's : Dr. Emmet
by Paul Ehrlich
In a previous issue of the Walker Hall Review, we
have presented some reminiscences of Professor Jane
Maxwell Day at San Jose State about our former col-
league Professor C. Basel Smith. In this issue, we present
what Professor Emmet Low, our 12th Ph. D. student with
supervisor C. Basel Smith, has kindly recalled ofhis grad-
uate student days in Gainesville and also his subsequent
career. Low received his degree in June, 1953, writing on
the topic "Vertical Loading on a Straight Boundary of an
Orthotropic Plate."
"Since you are working with the history of the de-
partment, it might be of interest to look at the history of
one of the persons strongly influenced by the department.
I came from a broken home, my parents were divorced
when I was five and Mother moved from Illinois to Or-
lando with her three children. It was in the depression
and sometimes we had to use gifts of food and clothing.
When I was ten, Mother married a man who was a printer
with a fifth grade education. I graduated from Orlando
Senior High School in 1940 with reasonably good grades
and very high state test scores. However, going to col-
lege was not an option and I never even considered it.
My first full-time job was at the Food Palace, Orlando's
nicest grocery, as a general handyman working twelve
hours a day, seven days a week for ten dollars a week. I
note that until I enlisted in 1942, I gave my mother half
of everything I earned. However, I never felt disadvan-
taged or disabled,(I am essentially blind in one eye) and
never felt anyone owed me anything.
When I came out of the service the last of January
1946, my mother encouraged me to go to college. So, in
March 1946 at the age twenty-three, I enrolled in Stet-
son with no understanding of what a college was or what
going to college meant. I had several wonderful instruc-
tors who gave me direction and advice, and toward the
end of my third or fourth quarter, I decided to go to grad-
uate school after graduation from Stetson in May 1948.
I had completed my degree in approximately twenty-six
months. During that time, I also delivered the Deland
paper daily on a rural route and worked nights in a fill-
ing station on Main Street. I was invited to join a fra-
ternity after a year and I did, but I had little time for
extra-curricular activities.
I then went to the University of Florida with plans
to get my master's as quickly as possible so I could go to
work. It was a time of increasing enrollments, and so Dr.
Kokomoor insisted that I take a teaching assistantship
which I did with some reluctance. They handed me a

course outline for the general math course [ed., C 42] of
which I was to teach two sections. Incidentally, because of
the press for classroom space, many classes were taught
on a Tuesday, Thursday, Saturday schedule. I started
teaching with only a textbook and an outline. Somehow,
I made it through the semester."
Here's what Dr. Low's wrote about his early studies
during his first year in complex variables and in elasticity
"I must say the mathematical background I brought
from Stetson was weak and I became discouraged with
trying to do the level of work expected. I was in Basel
Smith's Complex Variables and Theory of Elasticity. The
first was fairly easy, but the Theory of Elasticity was
populated with several doctoral students, several faculty,
and one master's student and me and I felt over my
head. We were using things I had never heard of and
I felt lost sometimes. We rotated the presentations of
sections, and as the junior member of the group, I felt
uncomfortable making my presentations to person much
further along then I was. When I wanted to drop it, Dr.
Smith gave me some good support and encouragement
and I had no real trouble with it....
Dr. Smith was one of the best professors I ever had.
He was well organized and gave beautiful lectures. I
believe he had taken his Ph.D. at Wisconsin and had
worked for the U. S. Forest Products Laboratory in Wis-
consin prior to his coming back to Florida and continued
to do research for them and the Office of Naval Research.
I remember coming into his office one day and he was
very excited. Using the mathematics associated with the
theory of elasticity, he had just developed a way to make
plywood with an increased shear strength over regular
plywood. I note that commercial plywood is made with
an odd number of layers placed at right angles alter-
nately to accommodate possible warpage due to moisture
content changes. His method used an even number of
laminations placed at predetermined angles, but not at
right angles. One of its potential uses was in the build-
ing of hulls of mine sweepers which could have no ferrous
metals in them.
Dr. Smith had a lovely wife, a son and a daughter
and was a devoted husband and father. I remember his
telling me about his years as a student at the University
[ed., of Florida] where he was a champion tennis player."
Low wrote that he had gone from teaching general
mathematics C 42 for the Mathematics Department
to teaching the general physics in the University Col-
lege lower division, e.g., the course "Man in the Physical
Sciences." [It should be noted, however, that in 1939-
1940 for instance, 3 members of the mathematics faculty
were teaching this course as part of their teaching as-
"During my first year, I decided to go for a doctor-
ate and not stop with just a master's. I was interested
in not just mathematics, but also how it could be used

to answer questions in the real world. I took some en-
gineering courses on the side and ran across a problem
in prestressed concrete. So with the help of Dr. Smith
and Professor William Lincoln Sawyer, head of engineer-
ing mechanics, I wrote a thesis on predicting creep or
plastic flow in prestressed concrete. I flirted with leaving
school after my master's and going into the prestressed
concrete business, but decided against it. Who knows, I
might have been much wealthier, but I doubt I could have
had a better life than I have had.
That fall, I was offered a full time instructorship in
the physical sciences which I took with the understanding
I could continue to work on a doctorate. Incidentally, the
regular teaching load was fifteen hours which was five
classes. The first semester I taught five sections of the
same course and, by the end of the week, I could answer
the questions in class before they were asked.
The following year they moved me to physics full
time where I continued until I graduated and went with
the National Committee on Aironautics, now NASA. I
had one weak course in physics at Stetson and a ju-
nior level course in electricity and magnetism my first
year at Florida so I was not very well prepared to teach
physics. However, the way we think and work in mathe-
matics helped me function in physics with relative ease
and I really enjoyed seeing mathematics relate to the real
world through physics. Incidentally, some of the graduate
students in physics were good friends of mine and they
used to bring problems from their graduate courses to
me for help solving. With the good understanding of ba-
sic physics principles I had gotten from teaching physics
and being fluent in mathematics, I was often able to solve
their problems even though I had not had the physics
they had had. I have often used this as an example of the
importance of having a good mathematical background
for any students who expect to do any substantive work
in physics, chemistry, or engineering.
At that time, most of the mathematics department
was housed in Walker Hall and the physics department
in Peabody. There was a landing on the stairs leading
to the second floor of Walker where a copying matching
using a process with the name Ozalid as I recall. It
used a solution that included ammonia and, when it was
in operation, you did not linger long going up or down
the stairs. We used it to make copies of our theses and
dissertations then.
During my years of teaching physics, my office was
on the top floor of Peabody along with Morton Teller who
was in charge of the physics lab. One day, I went to
the bathroom for a moment and, when I returned a big
chunk of plaster from the ceiling had fallen on my desk
and chair. That someone who kept me out of trouble at
the University also kept me from being hurt apparently.
Panty raids occurred in the early fifties when the
male students would get together one night after dark,
go to a dormitory housing females, invade it and make off

with items of girls' underclothing. After a couple of these
episodes, the administration used the football team with
baseball bats to serve as guards for the girls dorms. I
recall some of the boys taunting the football players for
interfering instead of joining in the fun and the players
responded with it was their scholarships that were on the
line and they were not going to risk losing them just for
a little risque fun.
Some of the girls joined in the fun and would go to a
balcony and toss down armloads of clothing. The univer-
sity identified all of the participants they could and even
conducted searches of some of the rooms of suspected
participants looking for evidence such as girls undies.
At one of the disciplinary hearings, a young man from
South America was charged through evidence found in
his room. He commented that he thought the panty raids
were just an American college custom, that he had seen
pictures of panty raids in Life magazine recently that had
occurred on other campuses and, on the night of the raid
when the boys said, "Come on, we're going to raid the
girls dormitories," he went along for the fun. He stood
around watching and, when a girl tossed down a bunch of
underwear, he reached up and grabbed one as it floated
down to take back as a souvenir. He was let off, but
some students were expelled even though the semester
was almost over and they lost all credit for work in that
semester. I remember sitting in a meeting with some of
the administration as they discussed how to avoid or pre-
vent problems like these with students. One of the older
administrators commented, "Remember there are many
more of them than us and some of them are smarter than
we are, so we're not going to be able to stop all of it." I
often remembered his wise comments over the years as I
served as an administrator trying to deal with students.
Incidentally, times have really changed and many of the
actions taken by the administration then could not be
taken now.
Those years at Florida were a wonderful time in my
life. Dr. Kokomoor was a warm and understanding per-
son with a delightful family. He was ambidextrous and
could write quite well on the blackboard with either hand.
I believe his doctorate was from the University of Michi-
gan. He was an ordained Methodist minister and had
supported his family while working on his doctorate by
serving as a pastor in a church in Ohio [ed., actually in
Ann Arbor]....
The atmosphere around the University during those
years was really warm and pleasant and, I suppose, some-
what typical of the country for awhile in those postwar
years. Most of us seemed to know where we were trying
to go and went about our business in a friendly and co-
operative manner. I had never heard of drugs other than
alcohol, and I never became involved in it. Those years at
the University and the people with whom I worked and
played, I am sure, helped give me direction and values
that stood me well over the ensuing years. I am sure you

and your colleagues are doing the same for the students
who are going through now, it must be a little harder. I
attribute much of what I have been able to do and any
recognition I have received largely to those experiences
at the University ....
In January 1954, I went to NACA, where a colleague
and I developed methods to be used in the design of larger
aircraft that probably is still in use today. This was in the
McCarthy era and the atmosphere in governmental re-
search was uncomfortable. A friend, Jesse Oroshink, who
had received his graduate degree in physics at Florida
soon after I went to NACA, went to work there also.
His family was Jewish and had immigrated from Rus-
sia. Even though he and his brother had served in W
W II and were honorably discharged, he was forced to
leave because somebody thought he might be a security
risk. I had gotten to know Jesse quite well at Florida.
Through him, I learned a lot about Jewish culture and
developed, I believe, a more tolerant and understanding
attitude toward other cultures that served me well later.
So, after about eighteen months at NACA, I went to the
University of Miami in 1955 as an assistant professor of
When I started at NACA, I was assigned a problem
that involved the analysis of stresses around rectangu-
lar cutouts in circular semimonoque structures, better
stated as around window and doors in airplane fuse-
lages. It involved mathematics that included the use
of matrices. My work at Florida did not include matrices,
so I had to set about learning about them on my own.
It gradually developed into trying to solve systems of
integro-differential equations connected with difference
equations. We were not able to solve the whole system,
but after making some simplifying assumptions, we did
get some solutions. Of course, this is normal in almost all
applications and what we got was very useful. However,
when I went to Miami, one of the first things I did was in-
troduce a course on linear algebra, they did not have one
at that time, and it became one of my areas of interest.
I spent 1959 60 at the Courant Institute of Math-
ematical Sciences at New York University as a visiting
research scientist. I worked mainly with Joe Keller, but
also got a chance to know Peter Lax, Louis Nirenberg,
Fritz John, Richard Courant and several others. It was a
wonderful experience, and like my years at Florida, had
a lasting impact on my work."
Following his return to the University of Miami, Dr.
Low was promoted to Associate Professor, then circum-
stances propelled him into the chairmanship without the
rank of Professor. This was an interesting opportunity
as Low
"had a bent toward applied mathematics in a depart-
ment that was mostly pure mathematics, but they asked
me so I was willing to give it a try. I did develop a doc-
toral program and hired some good people including A.
D. Wallace and visiting professors like Paul Halmos."

Low then served as Associate Dean, later Dean of the
College ofArts and Sciences at Miami University. He also
held a joint appointment with engineering and taught
things like fluid flow, hydrodynamics and aerodynamics
while still in the Mathematics Department. He was in-
volved in the development of a biomedical engineering
program with the medical school. He also worked with
others on using radar to track hurricanes for the United
States Weather Bureau and comments in his letter that
the spiral bands around hurricanes happen to be the log-
arithmic spirals of basic calculus.
In 1972, Dr. Low decided to leave the University
of Miami. During the last six years at Miami, he had
been isolated from students and teaching as a result of
his administrative positions. He had hired a number of
Virginia Ph.D.'s in building the department, including A.
D. Wallace, so Dr. Low decided to relocate to Virginia at
a smaller school where he could be closer to students. He
decided to go to Clinch Valley College, as Dean of the Col-
lege. There he has enjoyed working with students from
the Appalachian mountains "with a lot of native ability
and good work attitudes." He retired as Dean in 1986 to
return to full time teaching. The Department of Educa-
tion of Virginia was involved in setting up an electronic
classroom to offer courses in AP English and AP Calculus
in the high schools. So in addition to serving as depart-
mental chair and teaching four courses at Clinch Valley
College, Low took on the challenge of doing these televi-
sion lectures which were broadcast at high schools which
had too few students to offer calculus by themselves. Low
formally retired in 1989, but remains active helping res-
idents of the area with various mathematics problems

time of his death on January 1, 1955, he was 96 years
old and the oldest living graduate of West Point. Walker
fought in the Indian Wars and was subsequently honored
by membership in the Order of Indian Wars. He was
retired for disability after the Spanish American War, but
served nonetheless during World War I as a recruiting
officer for the state of Florida.
Walker served the University of Florida as Comman-
dant of Cadets and Professor of Military Science from
1908 until 1919 (i.e., he was in charge of the required
military training mandated for all (male) students) and
simultaneously taught in the Civil and Mechanical En-
gineering Departments in various capacities, with a ti-
tle like "Instructor in Descriptive Geometry" in the 1911
Record. Although Walker retired from serving as Com-
mandant of Cadets in 1919, he continued to teach on a
part time basis up until 1945, when he would have been
87 In the 1948 49 Record, Walker is listed as still
having an office on campus in Temporary Building G.

Alumni News

Antonio Quesada, Ph.D. in 1978 with supervisor
Professor Mark Teply, reports that he is a Professor in
the Department of Mathematical Sciences at the Univer-
sity ofAkron.
Natalie Millot, B.S. 1988, M.S.T. 1990, writes from
Dallas that she is now engaged as a Statistician and Tech-
nical Consultant at slp Inforware, Inc.
We are pleased to have recently received word from
Debbie Levinson, B.S. in mathematics in 1969, that
she is currently a Professor of Mathematics at Colorado
College. Levinson reports that after leaving Gainesville,
she moved to Tampa, where she took the MA and Ph.D.
at the University of Southern Florida in 1988, then held
visiting positions in the ULSF College of Engineering until
moving to Colorado in 1993. She sent me an e-mail report
"This is my third year at Colorado College. Colorado
College is best known as the selective liberal arts college
with the 'weird' calendar and nationally known hockey
team. The calendar is partitioned into 8 terms, called
Blocks, that last 3 1/2 weeks each. Our students take one
course per block, thus 8 courses per academic year. For
example, a student might take all of Calculus I between
Thanksgiving and Winter break in mid-December."
The reader may recall from the Spring, 1994 issue of
the Walker Hall Review,reading the news that Dr. Asha
Chapnerkar Vaidya, B.S. in mathematics in 1985, had
taken a position at Western Geophysical after receipt of
the Ph.D. in 1993 and also married Shekhar Vaidya (of
Haliburton Energy) in May, 1993. We are pleased to be
able to report the birth of a daughter, Poonam Vaidya, to
this couple on March 29, 1996. The baby, born at 6:06
a.m., was 8 pounds, 10 ounces and was 21 inches long.
Andrew Jauch, M.S. 1992, MEd. 1993, writes from
Pembroke Pines, Florida, that he was recently married
on August 5, 1995 in Moss Point, Mississippi (congrat-
ulations !!). He is currently teaching trigonometry and
physics at the Academy of Applied Technology and is also
an Adjunct Professor at Broward Community College. He
also asks to convey the message to Jorge Martinez,
Warren McGovern, and Mindy Herzog, congratss on
all your accomplishments !!!"
Patty Belinda Kim, B.S. in Mathematics, August
1995, writes from Centerville, Ohio, where she is holds
the position of B-2 Public Affairs Officer with the U. S. Air
Force: "Upon graduating from the University of Florida,
I received a commission as a second lieutenant from the
United States Air Force. I am currently stationed at
Wright-Patterson Air Force Base, Ohio. I work as the
B-2 Public Affairs Officer for the B-2 Program Office,
Aeronautical Systems Center. I'll serve in my current
position in a one year rotation. I'll then move (within the
B-2 Program Office) into a program management posi-
tion, which is in an acquisitions career field. My current

position gives me a great program overview of the acqui-
sitions of the B-2 Stealth Bomber. I firmly believe my
background in mathematics and my experiences at the
University of Florida helps and will continue to help my
career in the Air Force. Mathematics gave me an excel-
lent training to process information highly technical
information to reformat in many numerous fashions. I
sometimes find it strange that mathematics helps me to
communicate but not surprising."
Thanks to all of you, for sending in this material, es-
pecially to Patty for taking the time to write those help-
ful comments. Keep the information flowing back to us,

News from the CLAS Baccalaure-
by Kermit Sigmon, Associate Chair for Undergraduate Studies
At the CLAS Baccalaurette held on the afternoon of
May 3rd, two of our BS graduates in Mathematics were
recognized for their academic achievements:
Charlotte Antonelli was among the honored 4-year
scholars who graduated with a at least a 3.9 GPA. She
completed minors in both Statistics and Business Admin-
Eric Stone was among only eight Valedictorians
who graduated with a perfect 4.0 GPA. In addition Eric
was selected (by lot says the Dean) from among these
eight to deliver the Valedictory Address, the only student
to speak. His speech was delightful and entertaining.
Eric will be entering graduate school in mathematics in
the fall at Princeton University supported by a highly
competive NSF fellowship.
Congratulations to Charlotte and Eric as well as to
all our other successful degree candidates !
As a postscript, we are further pleased to report that
at the August 10, 1996 Commencement, mathematics
major Brent Snyder was named the Outstanding Male
Leader. He is being recognized for his extensive contri-
butions to residence hall projects and events. He served
as President ofBACCI II S, Boost Alcohol Consciousness
Concerning Health of University Students, and was also
on the national board of directors of the National Associ-
ation of College and University Residence Halls.
