Subject: Summary: Archimedes Was Not an Idiot
Several NA-netters wrote in. I'm not mentioning names because the
tone was not always friendly. I apologize for using nasty words like
"slander". To put the record straight, Henrici is just simply one
of my heroes, and Acton is a writer whose attitude towards computing I
share and whose style I enjoy.
The history of the unstable recursion (which was clearly invented as
a demonstration to students and never proposed as a serious algorithm)
can be traced back this far:
1. It is Problem 1-2 in the 1989 book "Numerical Methods and Software"
by David Kahaner, Cleve Moler and Stephen Nash, given with the
attribution "This problem was suggested by Alan Cline". (Although
the book is later than Henrici's, it does not cite Henrici at all.)
The technique is attributed to Archimedes with the erroneous
statement that Archimedes started from a square (it should be a
hexagon). It is correctly stated that Archimedes went as far as
a 96-sided polygon by a process of doubling the number of sides,
but how he did it, is not given.
2. Alan Cline comments: "I know nothing of the history of this method,
I'm afraid. Actually Roland Sweet mentioned the iteration to me
back in 1970 and I do not know what his source was."
Two more cases where the unstable recursion is, if not actually attributed
to Archimedes, at least not clearly distinguished from his work, have
been brought to light. In both cases, I have great admiration for the
work of the respective authors -- I just wish they had treated Archimedes
a little more fairly.
In "Numerical Mathematics: A Laboratory Approach" by Shlomo Breuer and
Gideon Zwas (1993), all five pages of Section 5.2, called "The method
of Archimedes", is devoted to the unstable recursion, starting from
a hexagon. Apart from the phrase "a variant of", there is nothing to
tell us that this is not what Archimedes did. In Section 5.3, devoted
to a short discussion of the instability, the authors admit "It goes
without saying that the Archimedean method cannot be blamed for the
loss of accuracy." and refer the reader to another book where a stable
formula is derived. In total these two sections use the name Archimedes
(or Archimedean) ten times without ever giving Archimedes's own algorithm.
In the well-known website www.mathpages.com, the article "Machin's Merit"
<http://www.mathpages.com/home/kmath373.htm> gives a slightly less
reprehensible but still unstable formula for t_k = tan(pi/2^(2+k)):
t_k = (-1 + sqrt(1+t_{k-1}^2))/t_{k-1}, t_0 = 1
saying "this is the same basic approach that Archimedes took", without
mentioning that the recursion is unstable, but giving a short summary
of what Archimedes actually did and, invaluably, a link to another
article <http://www.mathpages.com/home/kmath425/kmath425.htm> that
does give the correct algorithm and more.
On a still more positive note: the full story is well told in a highly
accessible reference.
G. M. Phillips, Archimedes The Numerical Analyst,
American Mathematical Monthly 88 (March 1981) pp. 165-169.
And if your library has Heath's "Works of Archimedes", the section on
the quadrature of the circle is well worth a read. To see Archimedes
come up with inequalities like
sqrt(5472132+1/6)/153 < (1009+1/6)/66
is just awesome. It demonstrates that the popular impression, as one
correspondent wrote, that "the Greeks were good with geometry but not
with numbers" certainly is not true in the case of Archimedes. Remember,
all this was done 1400 years before Europe learnt basic arithmetic via
Fibonacci from the Arabs!
Thanks for several stimulating e-mails -- even the unfriendly ones
qualify for that epithet!

Subject: JMSL Numerical Library for Java
Dear Colleagues,
Visual Numerics, Inc. is pleased to announce the availability of the
JMSL(TM) Numerical Library, Version 2.5. The JMSL Numerical Library
combines mathematical, statistical, and financial numerical analysis
capability from the IMSL(TM) libraries with charting for the development of
Java(TM) applications.
The JMSL library extends the Java platform by providing for the availability
of complex data types and complex number operations, such as abs, sqrt,
trig. functions, and conversions, for example. The library provides
functionality in areas such as matrix manipulation, linear algebra,
eigensystem analysis, quadrature, nonlinear equations, transforms,
optimization, cumulative distribution functions, regression, analysis of
variance, time series and forecasting, and classification, among others.
Version 2.5 of the JMSL Numerical Library adds algorithms for more advanced
optimization, classification for data mining, additional statistical
analysis, time series correlations, more advanced interpolation and
approximation, and new chart types. The JMSL Library V. 2.5 also adds a new
JMSL Application Quick-Start pack that provides working, documented code
examples that can be used in applications.
For general information on the JMSL Library, including links to the Function
Catalog and the API, please visit:

Subject: Workshop in College Park on Women of Applied Mathematics
Workshop Announcement & Call for Applications
WOMEN OF APPLIED MATHEMATICS: RESEARCH AND LEADERSHIP
Application Due Date is July 1, 2003
A workshop on Women of Applied Mathematics: Research and Leadership will
be held October 8-10, 2003 at the University of Maryland at College
Park. The workshop, consisting of research symposia and career
development panel discussions, will provide a technical and professional
forum for ten senior women and twenty-five early-career women (approx.
5-12 years post Ph.D.) in applied mathematics.
The workshop has two objectives:
* To provide advice and guidance to women who are a few years past
the postdoctoral stage and are now facing new challenges as they
transition to positions beyond entry-level.
* To provide networking among applied mathematicians who have
become, or are striving to become, leaders in their fields.
The following senior participants have committed to participate.
* Marsha Berger, Courant Institute
* Lisa Fauci, Tulane Univ.
* Maria Klawe, Princeton
* Deborah Lockhart, National Science Foundation
* Joyce McLaughlin, Rensselaer Polytechnic Institute
* Linda Petzold, Univ. California, Santa Barbara
* Cynthia Phillips, Sandia National Labs
* Dianne O'Leary, Univ. Maryland
* Mary Wheeler, Univ. Texas
* Margaret Wright, Courant Institute
We are soliciting applications from early-career women in applied
mathematics to attend the workshop. Participants will receive travel
expenses. After the workshop, early-career participants are expected to
lead an activity promoting women in mathematics and submit a report
detailing that activity. Early-career is roughly as several years past
the postdoctoral stage, at the point where one is nearing or just past
promotion and facing an increase in leadership responsibilities (e.g.,
leading research teams, being PI or co-PI on large proposals, and/or
pursuing opportunities in management or administration). Roughly
speaking, applicants in this category would be 5-12 years past the Ph.D.
Application instructions are available on the web site listed below, and
applications received by July 1, 2003 will receive full consideration.
Web site: http://csmr.ca.sandia.gov/~tgkolda/workshop2003/
This workshop is organized by Dianne P. O'Leary (University of Maryland)
and Tamara G. Kolda (Sandia National Labs). (Pending) Funding has been
generously provided by the Mathematical, Information, and Computational
Sciences (MICS) program in the Office of Science at the U.S. Department
