American Physical Society Announces Physics, A New, Free, Online Publication

Physics highlights exceptional papers from the Physical Review journals through expert commentaries written by active researchers.

Stay informed about the most important developments in your field and others by visiting APS's new, free website. Commentaries are written for broad accessibility and updated weekly.

Physics features three kinds of articles: Viewpoints are essays of approximately 1000–1500 words that focus on a single Physical Review paper or PRL letter and put this work into broader context. Trends are concise review articles (3000–4000 words in length) that survey a particular area and look for interesting developments in that field. Synopses (200 words) are staff-written distillations of interesting and important papers each week. In addition, we intend to publish selected Letters to the Editor to allow readers a chance to comment on the commentaries and summaries.

CERN's Large Hadron Collider

The Large Hadron Collider is scheduled to go live with its first major experiment on September 10th.

From their website:

The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

If everything you have read or seen is too technical, you can always fall back on a quick YouTube movie to make everything crystal clear.

Abstract

We present a procedure for inducing chaotic mixing based on a non-periodic patterning of the walls making use of the Weierstrass fractal function to generate the locations for the grooves. We show the numerical analysis of flow in three different geometries generated with the Weierstrass function and compare the results with a fourth geometry, quite similar to the staggered herringbone mixer (SHM) of Stroock et al (2002 Science 295 647), for which the patterning is periodic. We evaluate the Lyapunov exponents for massless and non-interacting particles advected by the flow and traced along the channels. We also compute the entropy of mixing for binary mixtures. Finally, we compute generalized (fractal) dimensions associated with the interface of the two fluids. The results show consistently substantial enhancement in mixing efficiency for two of the Weierstrass channels compared to the SHM.

Virtual Visit of the Canadian Space Agency

The Canadian Space Agency (CSA) was established in 1989 by the Canadian Space Agency Act. The agency operates like a government department. The president is the equivalent of a deputy minister and reports to the Minister of Industry. The president oversees five core functions: Space Programs, Space Technologies, Space Science, Canadian Astronaut Office, Space Operations. He also looks after six executive functions (Audit, Evaluation and Review; Corporate Management; Communications; Strategic Development; External Relations; Government Liaison) and three Corporate functions (Legal Services, Administration, and Human Resources). The President is supported by the Senior Vice-President and the Vice-President, Science, Technology and Programs.

Take a virtual tour of the John H. Chapman Space Centre. It is really well done and informative. It also makes a nice example if someone were creating a virtual tour of a library or laboratory within their organization.

Scientific Inquiries of Physicists

Studies like this could have great implications on how scientific students are educated in the future.


Analysis of the Actual Scientific Inquiries of Physicists I - Focused on research motivation
By Jongwon Park and Kyoung-ae Jang (June 27, 2005)

This study was investigated to understand the in-depth features and processes of physicists' scientific inquiries. At first, research motives were investigated by interviewing six physicists who were prominent worldwide. As a result, three main types - incompleteness, discovery, and conflict - and nine subtypes of research motivation, were identified. Six additional background factors were found which might affect the design and start of research. Based on these findings, implications for teaching scientific inquiries to students were discussed.
