University of Newcastle mathematician and Laureate Professor Jonathan Borwein is one of 17 scientists across Australia in 2010 to be elected to the Fellowship of the prestigious Academy of Science.
The Fellowship comprises Australia’s top scientists, recognised for research that has had a profound impact on the world’s scientific knowledge in fields including medicine, physics, mathematics and engineering. Laureate Professor Borwein is internationally recognised for his contribution to mathematics and computing education, and research in each of pure, applied and computational mathematics as well as high-performance computing.
For additional details see Announcement.
March 29. Borwein participated in the Distinguished Lecturer Series in Mathematics and Applications at the University of South Australia, speaking on “Entropy and Projection Methods for Inverse Problems”. For details, see Announcement and Abstract.
Abstract: I shall discuss in “tutorial mode” the formalization of inverse problems such as signal recovery and option pricing; first as (convex and non-convex) optimization problems and second as feasibility problems — over the infinite dimensional space of signals. I shall touch on the following topics (more is an unrealistic task):
1. The impact of the choice of “entropy” (e.g., Boltzmann-Shannon,Burg entropy, Fisher information) on

On 8 Mar 2010 Jonathan M. Borwein gave the First Plenary Lecture on “Exploratory Experimentation and Computation” (Lecture) at the 2010 German Mathematical Society meetings in Munich. An associated paper, co-authored with David H. Bailey, is here: PDF.
Abstract:
The mathematical research community is facing a great challenge to re-evaluate the role of proof in light of the growing power of current computer systems, of modern mathematical computing packages, and of the growing capacity to data-mine on the Internet. Add to that the enormous complexity of many modern capstone results such as the Poincaré conjecture, Fermat’s last theorem, and

Jonathan M. Borwein of the University of Newcastle (NSW, Australia) and Jon D. Vanderwerff of La Sierra University (California, USA) have published a new book “Convex Functions: Constructions, Characterizations and Counterexamples.” CARMA site | CUP site. Synopsis:
Like differentiability, convexity is a natural and powerful property of functions that plays a significant role in many areas of mathematics, both pure and applied. It ties together notions from topology, algebra, geometry and analysis, and is an important tool in optimization, mathematical programming and game theory. This book, which is the product of a collaboration of over 15 years, is unique in

On 3 Mar 2010 David H. Bailey of Lawrence Berkeley National Lab gave a “distinguished seminar” at the University of Delaware entitled “Computing as the Third Mode of Scientific Discovery.” The full lecture is available here: Online presentation.
Abstract:
The latest state-of-the-art scientific computer systems have achieved over 1 “Pflop/s” (one million billion floating-point arithmetic operations per second). Scientists have capitalized on this computational power by developing a wide range of sophisticated programs that are becoming so effective that scientific computing is now widely regarded as the third mode of scientific discovery, after theory and experiment.
In other words, the

Recently considerable attention has been drawn to the fact that some errors were found in the latest Intergovernmental Panel on Climate Change (IPCC) report, and the fact that, as revealed in a set of emails exchanged by some leading climate scientists in the U.K., the report had been “dressed” to some extent. Many now claim that there is a full-scale conspiracy of the scientific world to hide the “truth” from the public, a view now apparently held by 16% of Americans, according to a recent poll [Broder; Vanderhooft].
Similar claims have been made about modern evolutionary biology. The recent movie
