Subject: Fitting Experimental Data by Best Approximation
A scientist records observations Z to true values Y over a set X which
he believes is generated by a model F with parameter A (unknown). He then
obtains a ``near best'' approximation on X by F with parameter B to data Z.
He believes B should be close to A, at least if Z is close to Y.
Unfortunately no quantitative results have appeared and recent experinece in
exponential sums suggests that even if the closeness belief is correct,
constants are unfavorable. The situation may be so bad that data fitting for
the more complicated models F may be no more valid than astrology.
The author would be glad to exchange opinions and experiences with those
interested in this topic.

Subject: New Textbook, Introduction to Linear Algebra
New Textbook : Introduction to Linear Algebra
Gil Strang's new linear algebra textbook will be published for classes
this fall. It combines theory and applications, starting more gradually
than his current book - it is for a wide range of students. This basic
course can show how linear algebra is really used.
To go with the text Cleve Moler has written MATLAB Teaching Codes (even
including Cramer's rule) . Thanks go also to many people on NA NET who
suggested exercises. Reading the short codes in the text gives students
a new and different look at linear algebra . So does using them.
The preliminary version, for faculty only, will be printed in April.
Letters have gone to many departments with a reply card to Wellesley -
Cambridge Press, Box 812060, Wellesley MA 02181. You could write directly
to me at gs@math.mit.edu if this book might fit your department's plans.
Thank you.

Subject: Workshop on Industrial Postdoc Programs
INSTITUTE FOR MATHEMATICS AND ITS APPLICATIONS
IMA TUTORIAL WORKSHOP: HOW TO START AN
INDUSTRIAL POSTDOC PROGRAM
May 22 - 23, 1993
Supported by a grant from Special Projects Section,
Division of Mathematical Sciences, National Science
Foundation. Cosponsored by the Joint Policy Board for
Mathematics (JPBM)
The Division of Mathematical Sciences of the National Science Foundation
is considering modifications of its Mathematical Sciences Postdoctoral
Research Fellowship activity. The modifications may include the option
of an industrial postdoctoral fellowship. If approved by the Foundation,
the modifications are planned to be implemented in the fall of 1994.
This Tutorial Workshop is designed to discuss how interested faculty
from various universities might develop proposals for this modified
fellowship activity. It is anticipated that the fellowships may require
industrial matching funds and that each industrial postdoctoral fellow
will spend half-time on an industrial project and half-time working with
a university faculty mentor. Prospective mentors would be responsible for
initiating the industrial contact and securing university and industrial
commitments for the postdoctoral fellowships.
The overall program goal is to develop mutual research and technology
transfer between mathematics and industry through the mechanism of
(i)preparing math Ph.D's for productive research in industry, while
maintaining viable contact with universities and (ii) exposing math Ph.D's,
who will go into an academic career, to the excitement of industrial
research. Potential benefits to industry include contact through postdocs
to cutting edge knowledge, technology transfer at ``lower'' levels, and
hiring possibilities. Potential benefits to universities include a
broadening of mathematics research and education activities, and the
development of job opportunities for young mathematicians beyond college
and university mathematics departments. The immediate goal of the workshop
is to attract prospective faculty mentors from across the US and to show
them how to learn the language of industrial research and to nurture
relationships with industrial scientists to the level of developing a joint
industrial mathematics project.
Mathematics faculty interested in acting as a mentor for an Industrial
Postdoc are invited to apply to attend. Those who wish financial support
for their travel and local expenses should submit their vitae and a
statement of interest and background appropriate for a faculty mentor.
The registration cost is $16 for the dinner. To preregister contact the
IMA (or obtain the registration form and schedule by anonymous ftp at
ima.umn.edu and return it) by April 14, 1993.
The program will feature (in order):
Richard Herman, Director, JPBM
Avner Friedman, Director, IMA
J. Allen Cox, Honeywell researcher
David Dobsen, former IMA Industrial Postdoc

Subject: XIII Parallel Circus
SECOND ANNOUNCEMENT
XIII Parallel Circus
Urbana, Illinois
April 23-24, 1993
The Parallel Circus is an informal meeting of the numerical
analysis community with particular emphasis on parallel algorithms
for scientific computing. The XIIIth Circus will be held this spring
and will be hosted by the Department of Computer Science and the
Center for Supercomputing Research and Development of the University
of Illinois at Urbana-Champaign.
As with previous Circuses, we hope to have many attendees from
the USA, Canada, and other countries. The circus is unique in that
it is very informal, and thus allows us to talk about the very
latest results as well as interesting work in progress. In previous
meetings there have been many informal discussions and a good mix
of attendees from universities, industry and national
laboratories. Although there are no proceedings, a circus diary
is kept and posted in NAnet.
COMPLETE ANNOUNCEMENT
Complete announcements, including registration form, are available
via anonymous ftp from sp2.csrd.uiuc.edu (128.174.162.51) in directory
CSRD_Info/announcements. Get file pc13.1ascii (ASCII) or pc13.1ps (PostScript).
These forms can be also obtained by sending e-mail to csrd_info@csrd.uiuc.edu
with the single line request "send pc13.1ascii from announcements"
for the ASCII version. A nicer PostScript version is available sending
the message "send pc13uenc.1ps from announcements".
To restore the latter you must run it through "uudecode" first.
SCHEDULE
The actual lengths of presentations will depend on the
number of participant that wish to speak. Experience shows that
it is reasonable to plan for 30 minute long talks, including questions
and discussion. The circus will begin on Friday morning and
end Saturday afternoon. The schedule of talks will be set
Friday morning. Participants who give a talk and leave are generally
regarded as anti-social, so you should plan to attend all
of the talks. A major event of the Circus is the Friday evening dinner,
to be held at a local restaurant.
GRADUATE STUDENTS
Graduate students are especially welcome. There is modest
support from the National Science Foundation for student travel
to the Parallel Circus. Those students requesting support
should give reasons for attending the meeting and a budget
for expenses. The student(s) should indicate their research
interests and plans; a one page abstract of
a proposed talk is desirable. A letter verifying that
the student is in good standing should be sent
independently by a faculty adviser. This letter should
give the student's GPA. We will be pleased to consider joint
proposals which would include the expenses of several students.
Send your application to:
FAX: (415) 723-2411 (Write "Student Support" on Fax.)
E-mail: pc13@sccm.stanford.edu
REGISTRATION
Registration is important. Due to space limitations
we must limit participation to the first 100 registrants.
There are no registration fees but attendees are responsible
for their expenses, including dinner Friday night.
Note however that the restaurant will be reasonably priced. Please
address your registration form and enquiries for local arrangements to
