modeling

The International Conference on Mathematical Modeling in Physical Sciences is to be held at Prague, Czech Republic during September 1-5, 2013. The conference aims to promote the knowledge and the development of high-quality research in mathematical fields that have to do with the applications of other scientific fields and the modern technological trends that appear in them, these fields being those of Physics, Chemistry, Biology, Medicine, Economics, Sociology, Environmental sciences etc.

Topics
ICMSQUARE-2013 topics encompass, but are not restricted to, the following areas:

  • mathematical modeling in Fundamental Physics
  • evolutionary computation
  • complex physical and technical systems
  • software and computer complexes for experimental data processing
  • qualitative modeling including fuzzy and iterative approaches to modeling
  • nonlinear problems
  • computational chemistry, biology, and biophysics
  • new generation computing tools, distributed scientific computing
  • computational modeling in engineering and science
  • multiscale modeling, multiphysics modeling
  • progress in discretization methods
  • financial mathematics and mathematics in economics etc.

Venue
The conference is to be held at Prague, Czech Republic during September 1-5, 2013 at the Conference Center of the Orea Hotel Pyramida 4*. The hotel is situated by Hradcany and Strahov, within walking distance from the Prague Castle, Loreta, Strahov monastery and the Lesser Town. The Conference Center of the Hotel Pyramida offers ten fully air-conditioned conference rooms. Together they can accommodate up to 1100 people.

The London Mathematical Society response to inquiry on Open Acces

Leave a comment

lms
The London Mathematical Society has responded to the House of Lords Science and Technology Select Committee inquiry into open access publishing. The response can be found below.

We have long been concerned about the threat to our Society from the implementation of open access policies which seek to reduce the level of library sales by making the content of journals available to readers through alternative routes.

The Institute of Physics has also responded, follow the link below.

Some Julia sets

Leave a comment

julia1

Above is the Julia set of \(F_{c} = e^{z^{3}}\) at the point \(– 0.621\).

julia2

Above is the Julia set of \(F_{c} = (1+z+ \frac{z^{2}}{2})Exp[z^{-3} -z]\) at the point \(-0.6 -i\).

julia3

Above is the Julia set of $latex F_{c} =-\frac{\cosh \left(-z+1+\frac{1}{z}-\frac{1}{z^2}+\frac{1}{z^3}\right)}{|z|}+\sinh
\left(-z+1+\frac{1}{z}-\frac{1}{z^2}+\frac{1}{z^3}\right)$ at the point \(-(0.62-0.4 i)\).

I have posted other Julia sets here.

Some more IFS fractals

2 Comments

IFS

Above is another iterated function system fractal my wife and I created. You can see the self-similarity of the “swirls” clearly. We are both pleased with this one.

IFS

This one has a rather organic shape. You can see that this one consists of overlapping spirals and almost a ghostly appearance.

IFS

The above is similar to the first IFS system fractal we created together. It has a spongy-organic look to it.

You can find other IFS fractals we have created here and here. We may post more in the future.

The Myth of Academic Excellence?

1 Comment

Walter F.Wreszinski has written a short article called “The Myth of Academic Excellence and Scientific Curiosity” in the January 2013 edition of the News Bulletin of the International Association of Mathematical Physics [Wre]. It makes for some thought provoking reading…

The journals which we will call top A, of high “impact factor” (a rather controversial number analysed in detail in [Bin]), boast of high rejection indices, which reach 95 per cent, encouraging referees to recommend refusal in the almost totality of cases in order to justify this so important “measure of quality.” Thus, a major objective of these journals became the search for justifications to substantiate refusal, resulting in a one sided, and therefore unfair and unrealistic, view of the refereeing process.

Another interesting sentiment is quoted below.

We see that the main obstacle to the truth becoming known was the false concept of excellence associated to peer-review in top-A journals. A rejection to publish there leads to publication in a “non top A,” but this is equivalent to impart a label: the author did not succeed in publishing in top A, therefore the contribution is not first rate.

About Walter F.Wreszinski
Walter F.Wreszinski is a native of Rio de Janeiro (Brazil) and obtained his Ph.D. in 1973 at the Seminar für Theoretische Physik der ETH, Zürich, in the field of mathematical physics, having Prof. Dr. K. Hepp as thesis advisor. Since 1990 he has been full professor at the Departamento de Física Matemática, Instituto de Física, USP (University of São Paulo). His main research interests are mathematical statistical mechanics and quantum field theory.

2013 Mathematical Art Exhibition Awards

Leave a comment

The Mathematical Art Exhibition Award “for aesthetically pleasing works that combine mathematics and art” was established in 2008 through an endowment provided to the American Mathematical Society by an anonymous donor who wishes to acknowledge those whose works demonstrate the beauty and elegance of mathematics expressed in a visual art form. The awards are US$400 for Best photograph, painting, or print; $400 for Best textile, sculpture, or other medium; and $200 for Honorable Mention. The Mathematical Art Exhibition of juried works in various media is held at the annual Joint Mathematics Meetings of the American Mathematical Society (AMS) and Mathematical Association of America (MAA).
