Gracias, Jordi S. !!

Hace unos cuantos años. La ambulancia me recogió en casa en un charco de sangre que manaba por las muñecas y me llevo a un sitio conocido como "La Rotonda", que ahora ya no funciona como centro de urgencias psiquiátricas.

Estaba sólo, desorientado, jodido.

Encima tenía mucho frío. Era invierno y yo sólo llevaba una camiseta de manga corta. Por supuesto, no me ofrecieron un jersey o algo así.

Sólo Jordi me ofreció una camiseta suya, roja, de manga larga.

Ahora hemos vuelto a encontrarnos en las calles de la ciudad por casualidad.

No lo he olvidado: GRACIAS JORDI !!

Physics Resources on the Web

Knol: A unit of knowledge:

--------------------------------------------------------------------------------------
Useful Physics Resources on the Web:

The world wide web is a rich source of information about physics. The Physics FAQ is not the place to put together a complete list of them so I will concentrate on databases which are packed with useful content such as physics news.

The Internet Pilot To Physics
This ambitious web project is a good place to start your search for physics resources. TIPTOP includes The Net Advance of Physics and much more.

American Institute of Physics
The AIP publishes and archives a number of informative newsletters including PHYSICS NEWS UPDATE which is posted regularly on usenet. This is a good place to look for brief reports on recent discoveries.

High Energy Physics Information Centre
At HEPIC they keep archives of various newsletters from physics centres which often give useful information about the latest finds in High Energy Physics. And so much more...

The American Physical Society
They publish some of the most important Physics Journals such as Physical Review. On-line access to those is restricted but the What's New physics bulletins are a useful resource.

The Institute of Physics
Another journal publisher with a News in Physics section.

Los Alamos E-print Archive
These archives have become the primary means of communicating new papers in the fastest moving physics disciplines. This is where you will find hep-th, gr-qc, astro-ph and others.

SPIRES Databases at SLAC
There are a number of databases housed at SLAC under SPIRES. The most useful is the HEP Database which can be used to search for papers in High Energy Physics by author or title keywords. Recent papers can then be obtained through direct hyperlinks to the e-print archives.
Particle Data Group
This is where you will find the Review of Particle Physics containing values for all manner of physical constants. They have also put together an educational feature called The Particle Adventure.

John Baez's Papers
Useful information on developments in physics including the archive of This Week's Finds in Mathematical Physics. John has also put together a tutorial on General Relativity.
National Institute of Standards and Technology
Another site with convenient tables of physical constants

FreeHEP
A collection of free software for High Energy Physics

The Laws List
An alphabetically ordered list of laws and principles of physics by Erik Max Francis.

Treasure Trove of Physics
Another alphabetical list of physics definitions and equations by Eric W. Weisstein.

The Computers in Physics Education Committee
provides PhysicsEd: Physics Education Resources, a project to have a site which points to the all the known physics education resources on the net. Alan Cairns currently maintains this site.

MacTutor History of Mathematics Archive
This is an extensive archive of historical information which has good coverage of physicists and astronomers as well as mathematicians. Go straight to the search page and enter the name of your favourite physicist or topic

Physics Time-Line
A chronology of fundamental discoveries in physics from the ancient Greeks until today.
If you still have not found what you are looking for try the Yahoo index to physics. The web is a vast resource on all subjects and you may find what you are looking for by searching it using one of the larger search indexes such as Alta Vista or HotBot. It is also a good idea to search old usenet posts using DejaNews.
