LHC: some details about the software

March 31, 2010 Leave a comment

Yesterday represented a large milestone for the LHC. Here’re some details on the software.

You can also view LHC’s real time status here and here, the latter being the more interesting from a technology and visualization perspective.

Scale

Ever wonder about the relative sizes of the Solar System, or the Universe, or the cells?

Poor LHC can’t seem to catch a break

No, this isn’t from The Onion.

Further investigation into the failure of a cryogenic cooling plant revealed an unusual impediment. A piece of crusty bread had paralysed a high voltage installation that should have been powering the cooling unit.

Free videos at CosmoLearning

With the Year of Astronomy slowly drawing to a close, here’re 500+ free documentaries and videos on the subject. The list includes complete series, like Cosmos, The Planets,  and one of my favorites (though the book is still better).

It’s worth noting that the site hosts much more free educational content on a variety of subjects.

Got to find a printer capable of printing this behemoth, in color!

An explanation of the Analemma we see

August 26, 2009 Leave a comment

Ethan Seigel has uploaded a good post on the complex topic of the Figure 8 analemma that we experience from Earth (something I find difficult to visualize).

PS: There are several other posts, like the last 100 years series, all linked here or here (if you wanted to see them in a chronological order, well, sort of anyway, based on the search results), on his blog that, I think, are worth perusing.

Kepler: Early results

August 6, 2009 Leave a comment

The Bad Astronomer has the scoop on Kepler.

I haven’t yet found too much information about the behind-the-sceen storage and processing technology but am definitely interested in it.  While it may not be a real-time CEP system like the LHC (and here), it still wouldn’t be your average large scale, high volume system. From a press release:

Over the course of the Kepler mission, NASA Ames anticipates requiring between 30 and 90 terabytes of capacity to allow storage and analysis of images captured by the telescope. The precise amount of capacity actually required depends on several variables so it cannot be determined at the outset.
