After smashing atoms together for 26 years, the Tevatron particle accelerator powered down on Friday. The 4-mile-long ring-shaped accelerator, located at the Fermi National Accelerator Laboratory in Batavia, Ill., was built to hurl tiny bits of matter at each other in the hopes that they would break apart into the basic building blocks of the universe. Though the Tevatron made major discoveries, it became essentially obsolete after the Large Hadron Collider in Geneva began conducting experiments in 2009.
University of Pisa physicist Giovanni Punzi has worked at the Tevatron since it generated its first collisions in 1985. He talked about the Tevatron on Wednesday, two days before it was shut down.
What made the Tevatron special?
The Tevatron was the highest-energy collider in operation for a very long time.
What does the Tevatron do?
It collides protons and antiprotons. We have particle detectors situated where we can analyze the products of these collisions and find what new particles are there.
Why would you want to do this?
When you get the highest possible energy in collisions of particles, you reproduce a level of energy that doesn't exist today. It only existed at a very early stage in the universe, after the big bang. Creating such energies lets you see new phenomena — including particles that are not found in ordinary matter. So you can study the very basic laws that underlie everything we see and are at the basis of the evolution of the universe.
It's a frontier of knowledge. You get to see things that have never been seen.
What did the Tevatron find that had never been seen?
A number of observations and precision measurements that have added to our understanding of high-energy physics. And the top quark was discovered here in 1995. That was a very big discovery.
Why was it important to find the top quark?
The top quark was crucial because without it, all of our theories of how subatomic particles behave wouldn't work. Quarks are the fundamental particles that combine to make protons and neutrons, and physicists knew there had to be a sixth quark. Everybody was puzzled by the fact that we couldn't find it. The reason we couldn't find it is because its mass was so large that scientists could not produce it until the Tevatron came along.
It was a very long search. If we had not found the top quark, understanding all of the rest of the physics would have been a problem.
How did physicists study basic particles before the Tevatron was built?
Before this machine they had proton-antiproton colliders at CERN [the European Organization for Nuclear Research] in Geneva, but they operated at lower energies.
I remember people saying it would be impossible to put together a thousand magnets and make them work at the same time. But the people here did it. People get used to the idea of doing something that yesterday was considered impossible. It pushes everybody to their best.
Now, of course, the record is going back to Geneva because CERN has built an even bigger machine — the Large Hadron Collider. It's 31/2 times more energetic than the Tevatron.
The Tevatron played a big role in the search for the elusive Higgs boson, the so-called "God particle" that gives rise to mass.
Yes — the Tevatron was able to restrict the possible mass of the Higgs boson to quite a small range.
And even though the collider will no longer operate, you'll continue that search?
Yes. We've used just a fraction of the data we have, and we've been improving analysis techniques over time. So now we want to give it our best possible shot and see what we can figure out about the Higgs boson.
The Large Hadron Collider is also looking for the Higgs. But we look for different modes of decay of the Higgs boson: two different faces of the same coin. Even if the Higgs is seen in Geneva, being able to see it here will be very important to confirm and to understand the nature of this particle, which up to now is completely mysterious. We will be certainly adding to the knowledge of this thing.
Who decided to shut down the Tevatron?
The Department of Energy (which operates Fermilab) and the lab directors decided it was time to go into new projects. We proposed last year to keep going and take some more data, but the decision was to begin exploring what's known as the "intensity frontier."
What does that mean?
Rather than going for the highest-possible energy of collisions, we will go for very intense beams with very large numbers of particles. Using these, Fermilab will produce a large number of collisions that will let scientists look for very rare processes. What they cannot make in terms of energy they try to make up in terms of intensity and frequency of the collisions.
There are a whole lot of things that have been developed here, especially on the side of neutrino physics, that require very intense beams.
Last week, physicists at CERN reported that they had measured neutrinos traveling faster than the speed of light. Scientists around the world are now trying to see if they can replicate that result — including a team at Fermilab, right?
Yes. This raised lots of discussion. Most of us were thinking this is too strange to be true. If it is really true it's a violation of the fundamental laws of physics. It's really beyond anything we've seen in the past.
What will happen during the shutdown on Friday?
We'll simply stop doing what we've been doing. People will turn off the accelerator and turn off our detectors. Then we will concentrate on trying to get the final results from the data we've already collected.
How long will that take?
It depends on how interesting the results are. In principle it can go on for several years without a problem, but I anticipate that most of the things will probably come within a couple of years, no more.
Are people at Fermilab emotional this week?
How can't you be emotional when it's been so long and such a successful program? As I said, we have a group of people who are still willing to do more. People never got bored, for all this time.
How many colliders remain in the world?
Well, we have this very big one in Geneva. Apart from that we have smaller machines for doing specialized kinds of physics.
What will become of the Tevatron itself?
It's my understanding that Fermilab will reuse some pieces for the next accelerator and put others on display in a museum.

Sometimes we would walk to a nearby restaurant, where he would eat something very simple. Or we would go to a bookstore, searching for yet another book by Kipling or Conrad in an English edition for friends to read to him. People would stop to greet him, and he would jokingly tell me they must have mistaken him for someone else. His fame as a writer seemed to burden him, and he often regretted that he had to go on living so that Borges the writer could weave his literary fantasies. http://www.makeahistory.com/index.php/section-table/339-jlborges-on-life-and-death-interviewSometimes we would walk to a nearby restaurant, where he would eat something very... more

Scientists today performed the "world's largest scientific experiment" and managed to smash protons together at three times the energy previously achieved in an attempt to search for the elusive "God Particle" to learn more about the make-up of matter and the universe.
Scientists cheered as the proton beams collided in the LHC in Geneva. Detractors of the experiment had expressed concerns that the device would create black holes that would swallow up the Earth and destroy all life but, touch wood, we're still here soooo...
The head of the scientific team who conducted the experiment, Fabiola Gianotti, said her team is thrilled:
"We got something like 40 events per second, which is the expected rate. It's the beginning of a new era of physical exploration," she said.
Two earlier attempts at collisions had failed. One setback occurred in November 2009 when a "bit of baguette" fell onto machinery and caused a fault. The incident was blamed on a bird.Scientists today performed the "world's largest scientific experiment"... more

(CNN) -- Violence erupted in the Swiss city of Geneva Saturday as a scheduled peaceful protest of a World Trade Organization conference turned violent and police had to use tear gas and rubber bullets.
Thirty-three arrests have been made and police were on the streets working to maintain order, authorities said. There was one minor injury reported: An 80-year-old woman in a walker suffered a head bruise when she fell during the tumult of the demonstrations.
The demonstration started around 2:30 p.m. (8:30 a.m. ET) and about 3,000 people turned up in the central part of town, Geneva police spokesman Patrick Puhl told CNN. World Trade Organization ministers will hold a conference next week.
"There were three groups who came seeking violence," Puhl said.
"The troublemakers quickly began attacking banks, hotels and shops, smashing windows and burning four cars, so we had to stop them using tear gas and rubber bullets," Puhl told CNN.
The general theme for discussion at the conference is "The WTO, the Multilateral Trading System and the Current Global Economic Environment."(CNN) -- Violence erupted in the Swiss city of Geneva Saturday as a scheduled peaceful... more

The MPAA has successfully shut down an entire town's municipal WiFi because a single user was found to be downloading a copyrighted movie. Rather than being embarrassed by this gross example of collective punishment (a practice outlawed in the Geneva conventions) against Coshocton, OH, the MPAA's spokeslizard took the opportunity to cry poor (even though the studios are bringing in record box-office and aftermarket receipts).

Threats of cyberwar and a story of real violence rubbed shoulders at a news conference to mark the opening of the ITU Telecom World exhibition and forum in Geneva.
"The next world war could begin in cyberspace," warned Hamadoun Touré, secretary general of the International Telecommunication Union, the United Nations agency that organised the event.
The beginnings of such an unconventional war could be out of the control of conventional diplomacy, he said, because in cyberspace "there is no such thing as a superpower: Every citizen is a superpower." With an army of "bots," or compromised computers, at their command, almost anyone could wield great power in a virtual battle, as a number of recent denial of service attacks against targets around the world have shown.Threats of cyberwar and a story of real violence rubbed shoulders at a news conference... more

The weather and climate have a profound influence on our lives everywhere. Lives and livelihoods are disrupted in the path of storms and rising sea levels, retreating glaciers, intensifying droughts and floods, and food and water scarcity.
The Health and Climate Foundation has put together a contemporary art project that explores that relationship between climate and society.
Coinciding with the World Climate Conference 3 in Geneva, which runs from 31 August—4 September 2009, the exhibition is intended to provoke us to think about how we are affected by the environment, how it transforms us, and how we live with it.The weather and climate have a profound influence on our lives everywhere.

There are two videos on youtube and maybe even more that the Pope wanted a New World Order, here are the links:
http://www.youtube.com/watch?v=uQdt0TgD9Uc
http://www.youtube.com/watch?v=eAbhRxmA46I
and also the Pope wants a world peace and the last pope said that the next one is going to be the antichrist and in the bible it said even the antichrist wanted a NWO, so when you put all of this together the pope wants a new world order and nobody is standing in his way so this means the whole Vatican church is involved with the one world government.
Also when you look at the great ole Geneva it says on wikipedia: Geneva's economy is mainly services oriented. The city has an important and old finance sector, which is specialized in private banking (managing assets of about 1 trillion USD) and financing of international trade. It is also an important centre of commodity trade.
It said private banking and Alex Jones was saying that our entire world and America will be owned by private bankers and foreign interests.
Geneva is the new capital for the NWO and Inner London, Vatican City, and Washington D.C. will be it's capital comrades enforcing this one world government style regime.There are two videos on youtube and maybe even more that the Pope wanted a New World... more

GENEVA - Fixing the world's largest atom smasher will cost at least $21 millionand may take until early summer, its operator said Monday.
An electrical failure shut down the Large Hadron Collider on Sept. 19, nine days after the $10 billion machine started up with great fanfare.
The European Organization for Nuclear Research recently said that the repairs would be completed by May or early June. Spokesman James Gillies said the organization know as CERN is now estimating the restart will be at the end of June or later.
"If we can do it sooner, all well and good. But I think we can do it realistically (in) early summer," he said.
The organization has blamed the shutdown on the failure of a single, badly soldered electrical connection.
The atom smasher operates at temperatures colder than outer space to get maximum efficiency and experts needed to gradually warm the damaged section to better assess it, he said.
"Now the sector is warm so they are able to go in and physically look at each of the interconnections," Gillies told The Associated Press.
