This is a nice picture of the recent changing in Jupiter’s stripe pattern by Hubble Space Telescope. This is the first time that the changes are observed with such detail. New Horizons and some Earth-based telescope are also collecting huge amount of data in order to help to understand the atmospheric dynamics of the planet. [...]

From 9th to 13th July it is going to be another Statphys conference, the most important meeting in the Statistical Physics area. This year’s venue is Genova, Italy. The program can be downloaded from the conference site. Giovanni Gallavotti and Kurt Binder are receiving the Boltzmann Medal this year.
There are a lot of talks about [...]
More about the Pioneer Anomaly
Posted in Gravity, Pioneer Anomaly on June 22, 2007 | Leave a Comment »
It still remains elusive. This paper is going to be published in Physical Review D:
Could the Pioneer anomaly have a gravitational origin? – K. Tangen
The abstract:
If the Pioneer anomaly has a gravitational origin, it would, according to the equivalence principle, distort the motions of the planets in the Solar System. Since no anomalous motion of [...]
Nature Precedings
Posted in Nature, Preprints on June 22, 2007 | Leave a Comment »
Nature now has a service of preprints much like arXiv for biology, chemistry and earth sciences:
Nature Precedings is a place for researchers to share pre-publication research, unpublished manuscripts, presentations, posters, white papers, technical papers, supplementary findings, and other scientific documents. Submissions are screened by our professional curation team for relevance and quality, but are not [...]

An interesting paper about history of physics:
On the Dirac-Infeld-Plebanski delta function – O. Rosas-Ortiz
SOC and Gravity

Sometime ago, I found these interesting papers about self-organised criticality and quantum gravity:
Cosmology as a problem in critical phenomena – L. Smolin
Causal evolution of spin networks – F. Markopoulou, L. Smolin
Propagating spin modes in canonical quantum gravity – R. Borissov, S. Gupta
Self-organized criticality in quantum gravity – M.H. Ansari, L. Smolin
In the first two, self-organised [...]

Life changes. So do we.
Almost two years ago I started my second tentative to write a blog. My first tentative was a little miscalculated: I started three blogs with different themes. Needless to say, it took me very little time to realise that I would never be able to update regularly all three. But my [...]
