Huge $10 billion collider resumes hunt for 'God particle'
* An electrical failure caused a major shut-down of the collider in September 2008
* The full scientific program for the LHC wil probably last more than 20 years
* The LHC will look for the Higgs boson, quarks, gluons and other small particles
(CNN) -- Is the Large Hadron Collider being sabotaged from the future? Or merely by birds?
The LHC, the world's largest particle accelerator, has been under repair for more than a year because of an electrical failure in September 2008.
Now, excitement and mysticism are building again around the $10 billion machine as the European Organization for Nuclear Research (CERN) gears up to circulate a high-energy proton beam around the collider's 17-mile tunnel. The event should take place this month, said Steve Myers, CERN's Director for Accelerators and Technology.
The collider made headlines last week when a bird apparently dropped a "bit of baguette" into the accelerator, making the machine shut down. The incident was similar in effect to a standard power cut, said spokeswoman Katie Yurkewicz. Had the machine been going, there would have been no damage, but beams would have been stopped until the machine could be cooled back down to operating temperatures, she said.

As it begins to run at full energy, greater than any machine of its kind, the LHC will help scientists explore important questions about the universe. The ambitious project also has attracted its share of doubters.
Some alarmists expressed fear last year that the accelerator could produce a black hole that might swallow the universe -- a theory that LHC physicists, including Myers, dismiss as science fiction.
Another fringe theory holds that the LHC will never function properly because it is under "influence from the future," according to physicists Holger Bech Nielsen and Masao Ninomiya. They suggest in recent papers that no supercolliders that could produce the Higgs boson, an as-yet-unseen particle that would help answer fundamental questions about matter in the universe, will work because something in the future stops them.
This also explains the "negative miracle" of Congress canceling the Superconducting Supercollider project in Texas in 1993, Nielsen wrote in a paper on arXiv.org, a site where math and science scholars post academic papers.
"One could even almost say that we have a model for God," one who "hates the Higgs particles," Nielsen wrote.
But bizarre ideas about the LHC -- and in particular the debunked black hole theory -- have gotten more people interested in the whole project, said Joseph Incandela, professor at the University of California, Santa Barbara. He will be in the position of deputy spokesperson for the CMS experiment, one of the two general-purpose experiments at the LHC, as of January.
Although physicists such as Incandela have been working on the same questions and building accelerator experiments for decades, no one has paid much attention before now, he said. There were people who followed the topic, but not the broad audience that emerged in the past year or two, he said.
"Maybe it's just captured people's imaginations," he said. "It's really a wonder of science and technology to build such a large accelerator, a 27km-long machine that works at the precision of a fraction of the diameter of your hair," he said.
The results of the LHC experiments may help resolve fundamental problems such as the disconnect between Albert Einstein's theory of relativity, which describes the world on a large scale, and quantum mechanics, the laws of matter on a scale too small to see.
The LHC, located underground on the border of Switzerland and France, passed a proton beam halfway around the circular tunnel Saturday, undeterred by the bird incident earlier in the week.
The full-circle beam event scheduled to happen this month also took place last year on September 10 amid much celebration.
But just nine days later, the operation was set back when one of the 25,000 joints that connect magnets in the LHC came loose, and the resulting current melted or burned some important components of the machine, Myers said. The faulty joint has a cross-section of a mere two-thirds of an inch by two-thirds of an inch.
"There was certainly frustration and almost sorrow when we had the accident," he said. Now, "people are feeling a lot better because we know we've done so much work in the last year."
Even physicists who are not on the ground at CERN, awaiting for news from the LHC abroad, haven't given up.
When push comes to shove, the name of the game is 'what is nature,' and we're not going to know until our experimental colleagues tell us,"

Anti-Islam T-Shirts Banned in Florida School
Anti-Islam shirts draw suit
excerpt from the Gainsville Sun websiteUPDATE at 4:15 p.m. -- The American Civil Liberties Union has sued a central Florida school district. The lawsuit claims the Alachua County School District violated students' rights by not allowing them to wear T-shirts with an anti-Islamic message.
Jackie Johnson, school district spokeswoman, said they have not seen the lawsuit yet.
"We still stand by our decision to enforce our dress code to prevent students from wearing items that are distracting or disruptive to the learning environment," Johnson said.
Read the rest of the news article here:

Do you guys think this has political/religious/opinionated undertones? Are freedom of speech rights being oppressed? Is religious discrimination at foot? Could the offensive T-shirts be a from of hate crime? I thought it was an interesting, local article that might interest the class.

Canadian woman loses benefits over Facebook photo
Sun Nov 22, 1:20 pm ET
BROMONT, Quebec – A Canadian woman on long-term sick leave for depression says she lost her benefits because her insurance agent found photos of her on Facebook in which she appeared to be having fun.
Nathalie Blanchard has been on leave from her job at IBM in Bromont, Quebec, for the last year.
The Canadian Broadcasting Corp. reported Saturday she was diagnosed with major depression and was receiving monthly sick-leave benefits from insurance giant Manulife.
But the payments dried up this fall and when Blanchard called Manulife, she says she was told she was available to work because of Facebook.
She said her insurance agent described several pictures Blanchard posted on Facebook, including ones showing her having a good time at a Chippendales bar show, at her birthday party and on a sun holiday.
Blanchard said Manulife told her it's evidence she is no longer depressed. She's fighting to get her benefits reinstated and says her lawyer is exploring what the next step should be.
Blanchard told the CBC that on her doctor's advice, she tried to have fun, including nights out at her local bar with friends and short getaways to sun destinations, as a way to forget her problems.
Manulife wouldn't comment on Blanchard's case, but did say they would not deny or terminate a claim solely based on information published on Web sites such as Facebook.

Water on the Moon
I'm sure you've all heard about it in some way or another. It's important, however, to know what is really going on. A CNN article is good for general things, but NASA is a better place to read about it.
Many people think this mission threw an explosive at the moon, which just isn't true. Others think tinkering with the moon will destroy us - everything from messing up the tides to tossing Earth out of orbit. These people obviously have no clue as to how big the moon really is - and how throwing an object as small as LCROSS at it will change nothing..
Except our knowledge of water existing on the moon. A previous mission in India found the possibility of water there, and with the combined forces of them and NASA, discovered that there is more water on the moon than one would think.
This water is not like the water you know. It primarily exists in the moon's poles (which is why astronauts who went there did not find any; they did not go to the poles) as ice and water molecules. So it's not huge glaciers or bodies of water, but it is water nonetheless. Lots of CNN article commentators flip out about it - one side will warn humanity that we shouldn't touch the moon, and others say this could lead to huge developments for our species.
The people who say such NASA missions are a waste of time, effort, and money obviously don't use cell phones, calculators, satellite television, Velcro, ultrasound, and pacemakers - and don't drink Tang or cook on Teflon.

Terrorists in Illinois? What??
Gitmo in the Heartland?
This weekend President Obama's administration announced that it was looking at possible moving Guantanamo Bay prison detainees to a high security prison in Illinois. It makes sense to relocate some prisoners due to the over crowding of facilities in Gitmo, but is moving them into the middle of American Turf a smart Idea? High Security prisons are nothing new in Illinois, the state has several, but some people have the opinion that placing a high number of Al-Qaeda inmates in Illinois would raise the threat of terrorism considerably. It is not to far from Chicago, which is already at risk because it is a large metropolis city.Personally, it concerns me a bit because it is only about 100 miles away from my hometown. A few years back there were many incidents of large jail breaks in Illinois. One advantage of housing the terrorists in the Thompson Correctional Center is that it would create many jobs in the area..... Historically towns housing prisons have depended on the facilities to drive the local economy. When they are vaccant or closed down, the town all but dies and people move away.
But is it worth the risk?
No matter where the detainees are transferred to, some town in the U.S. is going to have the risk, burden and pressure of housing such dangerous criminals. Here is a small excerpt from the article:
U.S. Rep. Mark Kirk, R-Illinois, whose district covers suburban Chicago, circulated a letter addressed to President Obama to Illinois leaders Saturday, opposing the possible transfer of detainees. The letter says that doing so would turn metropolitan Chicago into "ground zero for Jihadist terrorist plots, recruitment and radicalization."
As home to Chicago's Willis (formerly Sears) Tower -- the nation's tallest building -- "we should not invite Al Qaeda to make Illinois its number one target," said the statement by Kirk, who is running for the same Senate seat once held by Obama.
"The United States spent more than $50 million to build the Guantanamo Bay detention facility to keep terrorists away from U.S. soil. Al Qaeda terrorists should stay where they cannot endanger American citizens."

Do You Believe in Global Warming???
United Nations Framework Convention on Climate Change. The writers and supporters of this treaty claim that if signed, it will lead to a greener, cleaner earth..... but at what cost? What are the actual economic, social, and political issues at stake here besides the "environment?"
Here is one side's view on the situation. The below video features
Lord Christopher Monckton speaking on the possible rammifications for the United States specifically if this treaty is signed.

Video nasty: Blockbuster employee 'stabbed himself in the leg to avoid working nightshift'
Aaron Siebers, 29, stabbed himself in the leg and told colleagues at Blockbuster he had been robbed in a bid to avoid working a night shift
I heard this one on the radio the other day. I know Blockbuster is going out of business (an inevitable layoff for this guy) but how stressful are minimum wage jobs really?!
