Subject: Gauss on Compatibility of Dimensions

Van Snyder told that "In 1822, Fourier observed that dimensional
analysis is important. One ought not to compare or add apples and
oysters, and multiplying length by area ought to yield volume, not
velocity" [NA Digest V.12, #43].

In 1809 Carl Friedrich Gauss published his major book "Theoria Motus
Corporum Coelestium In Sectionibus Conicis Solem Ambientium". [English
translation from Latin by Charles Henry Davis, "Theory of the Motion
of the Heavenly Bodies Moving about the Sun in Conic Sections",
Little, Brown and Company, 1857. Reprinted by Dover Publications Inc;
New York, 1963].

Such an orbit is defined by 6 parameters, which are connected with the
astronomical data (consisting of measurements of angles and of time)
by highly nonlinear equations. Gauss used N observations, where N is
much larger than 6. From initial estimates of the 6 parameters he
linearized the N equations, to get an overdetermined system of N
linear equations in 6 unknowns. Gauss invented the method of least
squares which he used to compute the most probable estimate of the
solution of the N linearized equations, and that process was iterated
until the 6 parameters had effectively converged.

He explained that if the N nonlinear equations have unequal
accuracies, then they should be scaled so that the scaled equations
have equal numerical estimates of their accuracy. "In this way it is
not even necessary that the functions V, V', V'', etc. relate to
homogeneous quantities, but they may represent heterogeneous
quantities also, (for example, seconds of arc and time), provided only
that the ratio of the errors, which might have been committed with
equal facility in each, can be estimated" (pages 260 & 261).

Thus, Gauss in 1809 warned his readers they they should not naively
try to add squares of heterogeneous quantities, such as angle and

Bavaria, Germany, visiting BGCE sites in Erlangen and Muenchen and
getting in contact with BGCE's educational and research program. The
main objective is to promote excellent students in CS&E and to foster
international exchange at an early career stage. Eligible for the
prize will be undergraduate and graduate students prior to receiving
their PhD (at date of submission).

Candidates are required to summarize their work in a short paper of at
most 4 pages. The prize finalists will be asked to present their work
at SIAM CS&E 2012 with a talk to be given in a special "CS&E Student
Prize Minisymposium" (on February 25, 2013). The papers and talks will
be evaluated by an international prize committee. Excluded from the
competition are only students from our own universities, FAU and TUM.
Deadline for submissions is December 16, 2012. Submissions should be

Subject: Winter School, Reproducible Science, Norway, Jan 2013

Winter School on Reproducible Science and Modern Scientific Software
January 20th-25th 2013.
Dr. Holms Hotel, Geilo, Norway.

It is a pleasure to announce that the 13th Geilo Winter School will
take place at Dr. Holms Hotel in the week January 20-25, 2013.

The Winter School will give an introduction to reproducible science
and modern techniques for scientific software development. A major
problem with the computational science community today is that many
published results are impossible to reproduce. This problem has
recently received a lot of attention, and the aim of the winter school
is that participants will be able to apply the learned techniques to
make their own research reproducible. Topics that will be covered
include reproducible research, verification and validation, software
testing, and continuous integration.

This years winter school will be given by four domain experts. Rasmus
E. Benestad is a Senior Scientist at the Norwegian Meteorological
Institute and author of several scientific books, André R. Brodtkorb
is a researcher at SINTEF, Johan S. Seland is the leader of the
Heterogeneous Computing research group at SINTEF, and Fernando Perez
is a researcher at U.C. Berkeley and the creator and lead developer of

Subject: 40 Years of Nested Dissection, Canada, Jul 2013

Workshop Celebrating 40 Years of Nested Dissection

Location: University of Waterloo, Waterloo, Canada
Date: July 22-23, 2013

Nested dissection was first described by Alan George in a 1973 paper
in the SIAM Journal on Numerical Analysis. The original algorithm
aimed at reducing fill in the Cholesky factorization of a sparse
symmetric positive definite matrix associated with a discretization of
a square domain, and was shown to be optimal in terms of nonzero and
operation counts, in the asymptotical sense. Many researchers have
generalized the nested dissection algorithm to more general sparse
matrices, both symmetric and nonsymmetric. Generalized nested
dissection uses a graph that represents the sparsity structure of the
matrix; this connection has motivated an enormous body of work in the
theory and practice of graph partitioning. Nested dissection and its
generalizations have been important in sparse matrix computation, from
theory to algorithms to software, implemented on serial and parallel
computers, from desktops to today's largest HPC machines.
Furthermore, nested dissection and its generalizations have also found
their way into other scientific applications, such as analysis of
social networks and data mining.

The year 2013 marks the 40th year since the publication of the
original nested dissection algorithm. A workshop will be organized at
the University of Waterloo on July 22-23, 2013 (with the possibility
of extending to July 24, 2013) to celebrate this occasion.

This workshop will review the successes of the past, as well as
looking forward to the future. The workshop will feature both invited
talks and contributed talks. Further information will be available
