... The overall globular cluster population is divided by gap in the metallicity function at [Fe/H]=-1.0 into two discrete groups with well-defined maxima at [Fe/H]=-1.60?0.03 dex, and -0.60?0.04 dex. ... Clusters with extremely blue horizontal branches occupy a spherical volume of radius ~ 9 kpc, have high rotational velocities ( V rot =77?33 km/s), have substantial and equal negative radial and vertical metallicity gradients, and are, on average, the oldest group (the old-halo subsystem). ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . THE CHANGING UNIVERSE: EVOLUTION HAPPENS! . b) Changes in Stars . One of the great discoveries of modern science is that stars (like people) live only a measurable life-time and then die. Although the lives of the stars are enormously longer than the span of a human life, we can learn about the life story of the stars by studying them at many different stages in their life cycle, from birth to death. ...

In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

In order to assist folks upgrading we are now going to maintain a document describing information critical to existing Apache users. Note that it only lists differences between recent major releases, so for example, folks using Apache 1.1 or earlier will have to figure out what changed up to Apache 1.2 before this document can be considered relevant. Old users could look at the src/CHANGES file which tracks code changes. ... There have been numerous changes to the default config files. ...
