First note that I have retired.
I no longer maintain an office at Georgia Tech. Look at my address above! I do
answer email. This is the best way to contact me when I am at home. When I
travel, my email is** **different.

What follows is a collection of things that please me. I list them in no particular order, give a brief description of what they are about, and provide a contact point to access more details.

**1. A New Interest: ** It is true that I have published a work of
fiction titled *Gathering Moss*. Publication date was January, 2008. Some
of the action in the book takes place on the campus of Georgia Tech, some at
the

**2. No More Same Old Calculus:
**Before I retired, Professor George Cain and I made a common observation:
most students entering Georgia Tech have already had the calculus. Because they
think they already know the calculus, they often fail to note that the college
course expects a deeper understanding of the concepts. Or, the students are
bored because their high school calculus was such a good course. Cain and I
wanted to make the materials fresh and exciting. Our decision was to present
the notions of calculus in a multidimensional setting at the outset. This would
take more time than typical in a second year calculus course because we would
constantly go back to re-look at the one dimensional setting from this
multidimensional perspective. Where could we find a text? Can you guess?

**3. Asynchronous Studies in
Undergraduate Partial Differential Equations: **Georgia Tech now offers graduate
programs in engineering where the materials stream over the web for students
scattered all over the country. I participated in this program for several
summers after I retired. The last time was during summer, 2006. There were
streaming lectures, class notes, detailed calculations, and a bulletin board
for class discussions. Some of these materials are
accessible from my web site.

**4. Notes for a course in Partial Differential Equations: **In the
Winter of 2003, I was commissioned to write a set of notes for studies in
classical linear partial differential equations and to publish these notes on
the web site for Maple Waterloo Software, Inc. These notes are available at
this site
with minor modifications from what appears at the Maple site. The modifications
occur as small changes are made to the text or to the models, and as additions
are created to amplify these ideas.

**5. An Introduction to the
Mathematics of Biology: **Unsuspecting students often are surprised that
mathematics could be so important in Biology. Even professionals are likely to
think that the mathematics of biology is statistics. Yes, statistics is important
in biology. There is also modeling. A good mathematical model for a biological
phenomenon can illustrate what is observed in life, can predict outcomes, and
can give directions for biological research. During the years before Professor
Edward Yeargers and I retired, we joined with Professor Ron Shonkwiler in
teaching an undergraduate course in mathematical biology. A text came
out of our joint efforts. You will find that I keep all the Maple syntax current,
as well as provide a list of errors we have
found after printing.

**6. Studies in the First Two
Years of Undergraduate Mathematics: **As students are introduced to the
concepts of undergraduate mathematics, they often wish to see applications of
the ideas. The models presented in this section have
evolved through teaching, as well as through discussions with faculty at
Georgia Tech and other universities. These studies are made available with the
hope that students will find the models give insight, and that other faculty
will use them in methods which seem appropriate.

**7. An Introduction to the
Linear Algebra of Infinite Dimensional Spaces: **Graduate students in
Mathematics and in several engineering disciplines include in their studies the
notions of Hilbert Spaces. It was a course that I taught often at Georgia Tech
and, consequently, developed a set of notes. The
notes are pretty compact. They serve as an introduction to studies in more general
infinite dimensional spaces.

**8. An Introduction to the Use
of Maple for Applications: **I am asked fairly often about how to accomplish
different type tasks with Maple. I created some materials that
can be used to get an introduction to the use of Maple for classroom
instruction and for analyzing applications from a variety of sources.

**9. First Order Differential
Equations with Periodic Forcing Functions:** In this Maple worksheet, we
consider solutions Y for the differential equation Y '(t) = A Y(t) + F(t). In
case A is a number and F is a real valued function, students in an introductory
calculus course often can make a solution for the equation. If A is a matrix,
students in an introductory ordinary differential equations course likely can
formulate a solution if F is vector valued. The interest here is a view for how
to handle this problem for A in a class of differential operators. We review
all three situations in this expository discussion. Our principal interest is
in periodic solutions in case F is periodic. The pleasure is in putting the
three settings into one context.

**10. MAA Short Course, March
2002**: At a joint regional meeting of the American Mathematical Society and
the Mathematics Association of America, Professor Ron Shonkwiler, Professor
Edward Yeargers, and I presented a short course on *An Introduction to the
Mathematics of Biology*. Notes
for the course are posted on this web site.

**11. Maple Conference, Summer 2006: **The Maple document
located at this site was
the basis of a presentation at the Maple Conference in July, 2006. The paper
was co-authored with Don
Jones . Using the diffusion equation
with periodic endpoint boundary conditions, the paper illustrates how to
compute both the periodic solution and the particular solution for a partial
differential equation with specified initial conditions. With three dimensional
graphics and with animations, the coalescence of the particular solution to the
periodic solution can be observed. A similar analysis is made for the wave
equation with periodic endpoint boundary conditions. Also, techniques are shown
for using Maple to compute numerical solutions for these equations.

**12. Connections:** Often I
get email inquiries from both sides of the Atlantic asking from where my family
comes. Usually, the author of the message wants to know if we are related. I am
fortunate to have several cousins interested in making these connections. I am
the second son of Joseph Wheeler Herod.
