Subject: Earliest Empirical Sharp Phase Transition in Linear Algebra/NA?

In recent years, several people [1,2] have found and given some
theoretical justification for the appearance of sharp phase transition
in the parameters space of problems related to solving linear algebra
problems. In particular; this is the case of undetermined systems of
linear equations where one of those parameters involve the sparsity of
the underlying solution. [1] was one of the triggering papers for what
is now known as compressive sensing, and has provided hardware/sensor
makers with the ability to better understand what could be measured
and what couldn't. It would be surprising however if the idea of sharp
phase transition did not occur earlier in linear algebra problems (not
just underdetermined systems) and that it did not rear its head before
2004 in some shape or form. My question to this august crowd is simple
and probably sound very ignorant (I am sorry in advance if I am
stepping on some, unknown to me, minefield): are there any empirical
and/or theoretically justified sharp phase transition in the area of
linear algebra or numerical analysis that have appeared in the
literature before 2004 ? I include in the word literature, any
technical reports that may not have had the opportunity to be
published in a journal as it was probably lacking some theoretical

Subject: James Clerk Maxwell's Poems on Mathematics

My thanks to all who replied to my note about the Edinburgh
Mathematical Laboratory. I learned that James Clerk Maxwell is another
famous son of Edinburgh. To his credit, Maxwell was both a
mathematician and a poet.

(On mechanics:

Gin a body meet a body
Flyin’ through the air,
Gin a body hit a body,
Will it fly? and where?

(On studying mathematics at Cambridge:

In the grate the flickering embers
Served to show how dull November's
Fogs had stamped my torpid members,
Like a plucked and skinny goose.
And as I prepared for bed, I
Asked myself with voice unsteady,
If of all the stuff I read, I
Ever made the slightest use.

This is parody of high quality. Maxwell wrote serious poems as
well. All can be found in
The excepts above are on pages 630 and 612.

Subject: New Book, Direct & Inverse Problems in Wave Prop and Appl

Direct and Inverse Problems in Wave Propagation and Applications
Edited by I.G. Graham, U. Langer, J.M. Melenk, M. Sini (2013)
Radon Series on Computational and Applied Mathematics 14

This book is the third volume of a three volume series recording the
Radon Special Semester on "Multiscale Simulation & Analysis in Energy
and the Environment" that took place in Linz, Austria,
October-December 2011. This volume surveys recent developments in the
analysis of wave propagation problems. The topics covered include
aspects of the forward problem and problems in inverse problems, as
well as applications in the earth sciences.

Wave propagation problems are ubiquitous in environmental applications
such as seismic analysis, acoustic and electromagnetic scattering. The
design of efficient numerical methods for the forward problem, in
which the scattered field is computed from known geometric
configurations is very challenging due to the multiscale nature of the
problems. Even more challenging are inverse problems where material
parameters and configurations have to be determined from measurements
in conjunction with the forward problem. This book contains review
articles covering several state-of-the-art numerical methods for both
forward and inverse problems.

It records the achievements of Workshop 3 "Wave Propagation and
Scattering, Inverse Problems and Applications in Energy and the
Environment" that brought together key numerical mathematicians with
an interest in analysis and computation of wave propagation problems
with practitioners from engineering and industry.

Large Scale Inverse Problems - Computational Methods and Applications
in the Earth Sciences (2013)
Edited by M. Cullen, M.A. Freitag, S. Kindermann and R. Scheichl
Radon Series on Computational and Applied Mathematics 13

This book is the second in a three volume series recording the Radon
Special Semester on "Multiscale Simulation & Analysis in Energy and
the Environment" that took place in Linz, Austria, October-December
2011. This volume tries to highlight and address commonalities in the
mathematical and computational procedures typically used in
large-scale inverse problems and in data assimilation within different
forefront applications.

The solution of inverse problems is fundamental to a wide variety of
applications such as weather forecasting, medical tomography, and oil
exploration. Regularisation techniques are needed to ensure solutions
of sufficient quality to be useful, and soundly theoretically
based. This book addresses the common techniques required for all the
applications, and is thus truly interdisciplinary.

It records the achievements of Workshop 2 "Large Scale Inverse
Problems and Applications in the Earth Sciences" that brought together
theoretical experts in inverse problems and data assimilation with
practitioners working on practical as well as theoretical aspects of
large scale inverse problems that arise in the earth sciences.

Subject: New Book, Simulation of Flow in Porous Media

Simulation of Flow in Porous Media - Applications in Energy and
Environment (2013)
Edited by P. Bastian, J. Kraus, R. Scheichl and M.F. Wheeler
Radon Series on Computational and Applied Mathematics 12

This book is the first in a three volume series recording the Radon
Special Semester on "Multiscale Simulation & Analysis in Energy and
the Environment" that took place in Linz, Austria, October-December
2011. This volume discusses new developments in computational methods
for the simulation of flows in porous media with applications in waste
storage, CO2 sequestration, hydrocarbon exploration and in the
mathematical modelling of fuel cells.

Subsurface flow problems are inherently multiscale in space due to the
large variability of material properties and in time due to the
coupling of many different physical processes, such as advection,
diffusion, reaction and phase exchange. Mathematical models for these
processes still need considerable development. However, significant
progress is needed to tackle important societal challenges, such as
long-term radioactive waste management and sequestration of CO2
underground. The book focuses on cutting-edge issues such as
multiphase flow and coupled flow problems.

It records the achievements of Workshop 1 "Simulation of Flow in
Porous Media and Applications in Waste Management and CO2
Sequestration" that brought together key numerical mathematicians from
the fields of analysis and computation of multiscale subsurface flow
and practitioners from engineering and industry.

Subject: PhD Position, UK Met Office

The Science Graduate School at the University of Bath is looking for
enthusiastic UK graduates wanting to do an exciting PhD in
Mathematics on the "Application of Multi-level Monte Carlo Methods
in Atmospheric Dispersion Modelling". This is an enhanced EPSRC CASE
Studentship in collaboration with the UK Met Office. EU Graduates
who have lived in the UK for 3 years can also apply.

The goal of this project is the application of multilevel Monte
Carlo methods (a novel variance reduction technique for stochastic
differential equations) to problems in atmospheric dispersion
modelling, such as the dispersion of a cloud of volcanic ash, or of
a smoke plume in an industrial fire. With your own implementation of
the method you will study the performance of the method for a range
of representative model problems from the Met Office. The aim is to
demonstrate and improve the effectiveness of the multilevel approach
in the atmospheric modelling context. As far as possible analytical
methods will also be employed to study the performance of the method
theoretically and to guide the design of efficient algorithms.
Depending on the success of the project, the method will eventually
be implemented in the Met Office’s operational model. For more
information see

We are looking for Maths graduates with a background in numerical
algorithms, numerical analysis, differential equations, and
computing, as well as an interest and basic knowledge of probability
theory. Alternatively, we also strongly encourage students with a
background in probability/statistics and a keen interest to expand
