Ice Cube Neutrino Observatory At South Pole

CmdrTaco posted more than 3 years ago | from the steady-obserbbin' dept.

Science 78

Scryer writes "Construction of the Ice Cube Neutrino Observatory was completed on 18 Dec at the South Pole. It's now the world's largest neutrino detector, with 5,160 optical sensors on 86 strings embedded two kilometers below the National Science Foundation's Amundsen-Scott South Pole Station. It has been gathering data since construction started, and will be fully operational after the last strings freeze in March 2011."

Then and Actor,

I think you are being more generous than when people said Schwarzenegger was an Actor.

Which was a surprise to Arnie, because all throughout his 'acting career' people basically bashed him for not really acting, just having enough muscles to hold up big guns. Then he runs for Governor and everyone goes "Ha! An Actor running for California Governor!" - greatest compliment he ever received.

bluefoxlucid (723572) | more than 3 years ago | (#34633826)

Schwarzenegger had some real human life behind his acting. He played the part but he played as himself. He played the part of a lifeless robot pretty good. He played his part in Last Action Hero as a no-bullshit cop pretty good. He never portrayed his character over-dramatized, fluffed, and out of sync with the reality he was in; the character was fluid and fitting.

If 'believable' is your criteria for a good movie then you're in for one hell of a disappointment. My main criteria are "interesting" and/or "entertaining", and Arnie made that happen in most of his movies, assuming you like that genre. I'm sure there are bunch of other genre's he'd really suck at, but to his credit he's stayed well clear of them.

I was actually saying pretty much the same thing. I enjoyed most of his movies immensely, but not because they were or weren't believable.

I think it you put him into gone with the wind or bridges of maddison county or some such classic he might not be quite so much fun though (or if he was, it would be for different reasons :)

I'm sure there is a specific definition somewhere, but a film would need to have been rammed down the throats of at least one generation of school kids to be considered a classic so yes, more than a year old.

Unfortunate choice of a name (4, Interesting)

mangu (126918) | more than 3 years ago | (#34633792)

There was a time when project names were chosen to be cute acronyms. I work with digital signal processing where there are algorithms named MUSIC, for "MUltiple SIgnal Classification", and ESPRIT, for "Estimation of Signal Parameters via Rotational Invariance Techniques".

Today it's better to have Google-friendly names, i.e. names that are unique. Every time when I start a new project name now I first google the name, if it gets any results I change the name. This is priceless for little-known projects, because any extra words you have to add to a search limit the results you get.

In the two examples I cited above, adding the word "algorithm" will return what you want, but how many pages are there in the web that mention MUSIC and ESPRIT without the word "algorithm"? Those pages are lost in the Google noise.

That hasn't really changed, how about: Antarctic Muon And Neutrino Detector Array - AMANDA?

That's what IceCube was formely known as, or rather, the IceCube array is an extension of the original AMANDA detector array.

Wrong Link (5, Informative)

icebike (68054) | more than 3 years ago | (#34633774)

The actual story is here
http://www.physorg.com/news/2010-12-icecube-world-largest-neutrino-observatory.html [physorg.com]

The key bits is this (should have been in the summary):

Under construction since 2004, IceCube encloses a cubic kilometer of clear ice, beginning one and a half kilometers beneath the surface and extending downward another kilometer. The telescope has to be this big because neutrino collisions with matter are exceedingly rare: out of uncounted trillions of neutrinos constantly passing through the ice, IceCube will observe just a few hundred a day.

Seeing them at all is only possible because when neutrinos collide with the nuclei of oxygen atoms in the ice, they turn into energetic charged particles called muons, moving in the same direction. Because these muons (and other debris from the collision) are moving faster than light can travel through ice, they radiate a shock wave of blue Cherenkov radiation visible to IceCube’s photodetectors.

How is the official home page of the observatory [wisc.edu] , which includes that story and more in the "News" column right smack-dab in the middle of the home page the "wrong link"?

Sure, maybe the summary could have included more information, or a link to a summarizing news story, but linking to the observatory's official presence on the internet is hardly the "wrong link".

Re:Wrong Link? Wrong. (1)

icebike (68054) | more than 3 years ago | (#34634422)

They linked to a page which had a link to the actual story.

How many levels of indirection are you prepared to accept?

Re:Wrong Link? Wrong. (1)

daveschroeder (516195) | more than 3 years ago | (#34634704)

The linked text was "Ice Cube Neutrino Observatory". The text linked to the official page of the observatory. The summary is about the observatory being complete. No indirection here.

Nothing implied that the link should be to an article. You assume that they "should" have linked to a news article, instead of the observatory itself. There is no such requirement of slashdot summaries, either implicit or explicit, and there is plenty of information about IceCube on the IceCube site [wisc.edu] . If the linked text implied that there was a news article behind it, you would have a point.

As for the content of slashdot summaries being bad or needing more informaton, I believe that is a perennial issue that transcends what submitters choose to link to.

Er, maybe there's no requirement as such.

But it does make a rather large amount of sense to have a link to an article describing the news that the story is about, if such a news article exists, and it does. And it makes sense to also have a link to the main website of the subject of the news story, if such a website exists, which it does. "Ice Cube Neutrino Observatory" should be linked to the main Ice Cube website, and "completed Dec. 18th" should be linked to the actual story.

And of course I mean "should" in the sense of "would be better", not "should" as in "to do otherwise is wrong". Still.

As for the content of slashdot summaries being bad or needing more informaton, I believe that is a perennial issue that transcends what submitters choose to link to.

Er, yes, but most of the time they at least have a link to a news item that's about the news that the story is trying to inform us about. Ones that don't are complained about even louder than usual, and for good reason I think.

Re:Wrong Link? Wrong. (1)

Scryer (60692) | more than 3 years ago | (#34635080)

There are lots of news stories about the completion of the neutrino observatory. I could have linked any of them, but I preferred to go to the source of the information rather than filtering it through a reporter -- especially when the source has perfectly accessible text that doesn't need a scientist to explain for us. If you want to see many news articles about it, Google News [slashdot.org] will find them quickly.

That was my first try at a submission -- next time I'll put more in the summary.

Re:Wrong Link (4, Informative)

Chris Burke (6130) | more than 3 years ago | (#34634684)

I think one of the neatest things about Ice Cube is that it is essentially using the entire freaking planet earth as a filter for muon sources other than neutrino interactions. It can detect what direction a source of Cherenkov radiation came from, and if it came from the direction of the sky then it's vastly more likely to have been caused by some other form of cosmic ray and neutrino interactions would be completely lost in the noise. Neutrinos can pass through the whole planet with ease, though, so by subtracting out the sky-originating muons, they are left with the probable neutrinos.

In fact I remember a Slashdot article from a while back where they took the data that they usually subtract out as non-neutrino noise and analyzed it, and were able to make some interesting discoveries about cosmic rays. Oh hey, found the article: http://www.physorg.com/news199468476.html [physorg.com]

Re:Wrong Link (1)

Anonymous Coward | more than 3 years ago | (#34635726)

A clarification: when a high-energy neutrino interacts to produce a muon, that muon can travel for several kilometres through rock/ice before it decays. So a neutrino could interact to produce a muon in the bedrock below the Antarctic icecap, and the muon could still travel up into the ice and be observed by IceCube.
