Subject: I. J. Good and colleague matrices

I would like to draw readers' attention to the passing
of I. J. Good last April 5, age 92. The recent London
Mathematical Society Newsletter observes that Good was
the longest standing member of the society, having joined
in 1940!

Jack Good had a prolific, varied, and influential career,
including working as Turing's statistical assistant and
close friend at Bletchley Park and the University of
Manchester, secret government work in the UK, and many
years as an increasingly legendary professor of statistics
at Virginia Tech. He was one of the key figures in the
development of Bayesian statistics and one of the first to
publicize the Bletchley codebreaking activities. But I
would like to highlight a less well-known contribution
he made to numerical analysis. We all know that the
roots of a polynomial are equal to the eigenvalues of a
companion matrix formed from its coefficients. Unfortunately,
rootfinding problems formulated this way are exponentially
ill-conditioned unless the roots happen to lie near near
the unit circle. For roots on an interval, however, there
is a well-conditioned analogue based on eigenvalues of a
"colleague matrix" made from coefficients in a Chebyshev
expansion. It was Good who discovered this and proposed
the name colleague, back in 1961. The same observation
was made independently by Wilhelm Specht one year earlier.
A number of people have rediscovered it since.

Call for Nomination for ICIAM Prizes for 2011

The ICIAM Prize Committee for 2011 now calls for nominations for the
five ICIAM Prizes to be awarded in 2011 at the congress in Vancouver.
Each ICIAM Prize has its own special features, while being truly
international in character. Nominations are therefore welcomed from
every part of the world. A nomination should take into account the
specifications for a particular prize,
see For convenience
shortened specifications are given at the end of this note.

The deadline for nominations is 21 September 2009.

The nomination should be sent to the President of ICIAM, Rolf Jeltsch,
preferably in electronic form. email:

Short version of the specifications of each ICIAM Prize
- Collatz Prize: For a mathematician under 42 years of age
for outstanding work on industrial and applied mathematics.
- Lagrange Prize: For a mathematician for exceptional
contributions to applied mathematics throughout her/his career.
- Maxwell Prize: For a mathematician who has demonstrated
originality in applied mathematics.
- Pioneer Prize: For pioneering work introducing applied mathematical
methods and scientific computing techniques to an industrial problem
area or a new scientific field of applications.
- Su Buchin Prize: For an outstanding contribution by an individual
in the application of mathematics to emerging economies and human
development, in particular at the economic and cultural level in
developing countries. This includes e orts to improve mathematical
research and teaching in those countries.
