Two new spotlights on relativity: The realm of relativistic hydrodynamics (in the category General relativity) and Of gravitational waves and spherical chickens (in the categories Gravitational waves and cosmology).

30 March 2007

Two new spotlights on relativity: Of singularities and breadmaking and The gravity of gravity (both in the category General relativity). Also, we have now installed an RSS feed that allows you to keep up to date with what's new on Einstein Online.

Two new spotlights on relativity: Gravitational deflection of light and The equivalence principle and light deflection (both in the category General relativity). Also, the spotlight text Extra dimensions - and how to hide them has received a nice new set of illustrations.

24 December 2006

Two new spotlights on relativity: Particle accelerators as black hole factories? (in the categories Relativity and the quantum and Black holes & Co.) and Changing places - space and time inside a black hole (in the category Black holes & Co.)

26 October 2006

Two new spotlights on relativity: Spacetime singularities (in the category General relativity) and A tale of two big bangs (in the category Cosmology)

28 September 2006

Two new spotlights on relativity: Gravity: From weightlessness to curvature (in the category General relativity) and The wave nature of simple gravitational waves (in the category Gravitational waves)

21 July 2006

We've reorganized two sections of Einstein Online. Since the number of our "Spotlights on relativity" has increased greatly since the first publication of this site, the usual Spotlights on relativity page now links to subpages with lists of texts in the categories Special relativity, General relativity,Gravitational waves,Black holes & Co., Cosmology, and Relativity and the quantum. Of course, in addition, there is still an extra page with a Complete list of all spotlight texts. Also, we have expanded the section that gives you information about the website itself. All such pages are now accessible from our new page About Einstein Online - existing pages like our List of authors and editors, but also new pages like a list of our partner institutions and a brief history of Einstein Online.
