Re:Good Slashdot post
Sounds like the dark galaxy called VIRGOHI 21 which might have ~1000x as much dark matter as visible matter (compare to ~10-20x for the Milky Way's ratio).

Dark Matter / Energy takes the "About PPARC" page
The link at the bottom of the page labelled "About PPARC" obviously goes too close to a singularity and ends up in a parallel universe with a quantum difference of this address is a 404 page. They've got me convinced.

Simulated Universe
Posted by Zonk on 2005-06-03 20:25
from the not-the-matrix dept.
anonymous lion writes "A story in the Guardian Unlimited reports on The Millennium Simulation saying that it is 'the biggest exercise of its kind'. It required 25 million megabytes of memory to take our universe's initial conditions along with the known laws of physics to create this simulated universe." From the article: "The simulated universe represents a cube of creation with sides that measure 2bn light years. It is home to 20m galaxies, large and small. It has been designed to answer questions about the past, but it offers the tantalising opportunity to fast-forward in time to the slow death of the galaxies, billions of years from now." -
The Volkswagen Connection: Setting the Stage for aGermany is the home to an automobile industry that is admired and respected worldwide. Their products range from low to high end, with almost every manufacturer commanding respect in their target demographics. From the success of introducing the world's first luxury marque at Mercedes-Benz, to pioneering the mix of luxury-sport at BMW AG, almost all German automobiles are revered. Lately, however, there has been one sore thumb in the almost exclusive group. That would be the long-heralded heritage of home-grown Volkswagen AG.
Volkswagen, literally "people's car," has been producing vehicles in Germany since its original founder, Adolf Hitler, brainstormed their first concept. Their niche was once to build a car that the everyday Aryan could afford, and to bring strength by empowering their people to commute cheaply and effectively where they needed to go. Today, Volkswagen is much more, representing an entry-level German nameplate for automobile owners to get the trademarks set by every German automobile: great styling, great handling, and prohibitively expensive repairs.
Their product repertoire includes several historical namesakes from previous generations, as well as modern day contenders in the 21st century automobile market. The New Beetle and the Jetta are Volkswagen's entry level vehicles for German beginners. Moving up the chain brings you the Passat and the Golf, for European luxury in midsize prices. At the top of the chain brings the near-luxury Touareg (German for "SUV") and Phaeton (German for "German Luxury"). What Volkswagen wants you to forget, however, is their rich lineage which spawned today's vehicles.
Founded in 1932 by the famed Nazi leader, his first project was to design a vehicle which would aid in building the strength of the fascist state. The car would be built to mimic the symbolic ideals of the cult-like ruling Nazi party. The Beetle, it was to be called, would be Volkswagen's first foray into enabling the Nazi leaders to commute to battle meetings to coordinate the death of the Allies. Throughout the War of Europe and subsequently World War II, Volkswagen earned the Nazi regime heavy profits due to its rapid expansion and slave labor. This, in turn, allowed Volkswagen to expand plants to newly-acquired German territory in Russia, as well as Czechoslovakia.
After the crumbling of the Nazi party, and effectively the entire German social structure in 1945, Volkswagen was left without its founder and entire management structure. Influenced by the opportunity of quick expansion, wealthy British entrepreneur Richard Branson, Sr. invested hundreds of millions of dollars into the plants to retool them for postwar production throughout Europe. Volkswagen was then reborn to make models that would carry its rich heritage to nations left unaffected by its founder.
Throughout the 1950's, 60's and 70's, the world went through major changes as a global economy started trickling into every nation.

Re:I hope they dont "believe" in it either.... yet
However, scientists are also human beings, and when many of them dedicate their entire career to string theory, you might say that they have a little more than a 'good feeling'.
Belief and faith are in my book two different things, and scientists believe a great many things. For a discussion of this see Edge Magazine.
On another note, as many others have posted here, proof of supersymmetry is, unfortunately, not proof of strings. But it is a step closer to one. A physics professor explained to me once that to probe the Planck length, you'd need an energy far beyond anything available to humanity for millenia to come. Something like the entire energy production of a star in its entire lifetime. So unless someone makes a really ingenious hack for this, we'll be stuck here for a while.
And if this one fails to provide supersymmetric particles, I have hopes that the Large Hadron Collider will. -
Re:Not enough buzzwordsyou know Mr.AC, somewhere in between your joking of quantum, my half-reading of this article and then my meandering over their interesting image I was struck with how strange this curling of DNA looked.
I mean, on one hand it looks tangled and inelegant. But then I think how it twists this way because of the fundamental laws of my favorite place (the universe).
Which then led to my recollection of the following (hope this image hosting doesn't bork:/)
I've just always wondered what the heck those curly clouds are? this is a high-altitude test of a megaton hydrogen bomb (this is the last atmospheric test by the united states, operation name "tightrope") so that blast is many kilometers (which are like miles) in diameter. those curly clouds intrigue me to no end.
the curves of nature amaze me...even if the math sometimes draws my antipathy. -
Re:Found some more info
Phooooey!
It chopped the end off my link.
I'll try again:
Here.
(The "Here" text above is DEFINATELY enclosed with correct HTML, and contains the full URL)
Hmmmmmmm, now thats interesting.
Slashcode is screwing the link up.
I will just paste it exact in plain text - it is balking on the "&style=update" parameter of the URL.
Here it is in plaintext:
http://www.pparc.ac.uk/frontiers/archi ve/update.as p?id=15U3&style=update
and incase all that fails, this is a working link to the archived issue, the HESS link is on the left hand side:

Found some more info
Went looking around for more information, and came up with this:
http://www.pparc.ac.uk/frontiers/archive/update.as p?id=15U3&
It includes a picture of the telescope array as well as a small image of the gamma ray map. -
And this one
HD70642 in Puppis 90 light years away...
I see a pattern forming...

Watch the news on the 25th of December
Beagle2 is expected to send its results just in time for Christmas. I have some reason to think its findings will be positive (namely: Gil Levin).
A short Media briefing can be found here. -
Re:Anti-europeanismNotice that the Beagle II - part of the Mars Express mission - is totally privately funded. Blur [1] and Damien Hirst [2] were involved and they helped to raise funds.
Sorry, there is no private funding of Beagle 2. It has been paid for as a consortium by the Department of Trade and Industry, ESA, the Wellcome Trust and PPARC. The involvement of Damien Hirst and Blur has been on a volunteer basis - both for their contributions and for the publicity they can give the project.
Best wishes,
Mike. -
Re:Why large filesDatabases.
The computer aided design databases for an automobile, when you have 3D models for the parts, the tooling, plant layout, etc. is in the low terabyte range. As another example, Boeing dedicates about 14 terabytes to commercial airplane geometry data storage.
Or Astronomy. A planning document talks about a project generating 300 terabytes per year.

Re:Astrophotography?
Since this new chip is able to gather more light than traditional CCD chips, I would imagine that there will be some interesting uses for it in astrophotography. Instead of having to use a CCD imager with a 30 minute exposure to get an image, wouldn't you technically be able to get a higher resolution pic with this a lot quicker?
All the serious astrophotography I've done has been carried out with single waveband CCDs and filters, rather than colour CCDs so you would get an equivalent depth of image with the old style CCDs to the new X3 sensor for the same exposure time. However, the X3 sensor provides the advantage of doing three bands simultaneously but I would want to see the data sheets for the wavebands for each layer to see whether it could be used for colour measurements. I suspect that if you want more than just a good colour piccy, you are stuck with the R, G, Gb, B, V, etc. filters.
Cheers,
Toby Haynes
P.S. in case you wondered which telescope I used for my astrophotography take a look
