Fermi labs
Antimatter discovery could launch new era of physics

CHICAGO - The discovery that a bizarre particle travels between the real world of matter and the spooky realm of antimatter 3 trillion times a second may open the door to a new era of physics, Fermilab researchers announced Monday.
The incredibly rapid commuting rate of the B sub s meson particle had been predicted by the Standard Model, the successful but incomplete theory aimed at explaining how matter and energy interact to form the visible universe. After 20 years of trying, scientists have now confirmed the rate, providing strong evidence for the theory.
The monumentally precise technology developed to measure the meson's back and forth dashes also may open the way to discovering a new family of fundamental particles and possibly a set of new forces that could be harnessed for technological applications, physicists suggested.
The discovery comes at a time when the future of Fermilab, located near Batavia, Ill., is in doubt. Its huge 4-mile circular Tevatron particle accelerator may be forced to close by 2010 if Congress does not approve construction at Fermilab of a multibillion-dollar, 18-mile-long International Linear Collider.
Without the collider, the United States would lose its lead position in high-energy physics discoveries to Europe, where a new accelerator seven times more powerful than the Tevatron is to start up within two years at a site on the Swiss-French border.
The meson finding shows that Fermilab, which began operations in 1967, is still capable of making breakthrough discoveries. Scientists there discovered two of the most fundamental particles, the bottom quark in 1977 and in 1995 the top quark, one of the constituent particles of protons, which form the nuclei of atoms.
Raymond Orbach, undersecretary for science with the U.S. Department of Energy, called the breakthrough "a triumph for Fermilab."
"This remarkable tour de force details with exquisite precision how the antiworld is tied to our everyday realm," he wrote in a statement. "It is a beautiful example of how, using increasingly sophisticated analysis, one can extract discovery from data from which much less was expected."
For all that scientists have learned about the universe it is still a mysterious place. Immediately after the Big Bang some 13 billion years ago equal amounts of matter and antimatter formed. Much of it quickly acted to annihilate the other, but for little-understood reasons a bit more matter than antimatter survived, providing the universe with the planets, stars and galaxies visible today.
Particles that bridge the two worlds, such as the B sub s meson, normally don't exist on their own but can be created in the great collisions generated by particle accelerators, which attempt to duplicate conditions close to the Big Bang. Studying the particles helps scientists understand the evolution of the universe.
Fermilab's Tevatron collides protons against antiprotons moving near the speed of light, producing about 10 million collisions a second. The key to interpreting this enormous amount of data is the CDF detector, a three-story-high instrument that measures the tracks of the particles exploding from the collisions.
Such experiments are big and expensive and require huge workforces. The meson experiment involves 700 physicists from 61 institutions and 13 countries.
Fermilab physicists are now more hopeful they may be able to find signs of even more elusive particles, such as the Higgs particle, which imbues matter with mass. Without the Higgs, it is theorized, matter would have no weight.
"We hope we will see either signs of the Higgs or the discovery of new physics," said University of Chicago physicist Ivan Furic, who called the new discovery "a morale booster."
"The options are still there," he said. "The Tevatron is still taking data."
"If there are unexpected types of particles that can communicate between matter and antimatter this is a very good place to find them," said team co-leader Jacobo Konigsberg, of the University of Florida. "It helps us see if there is room for even more exotic particles that can occur in nature, but they occur in such subtle ways that we are not aware of them."

Another good day
Had a great night last night with Mag, we went to see A Scanner Darkly, utterly trippy....
"Man I only count 9 gears, 6 at the back, three at the front"
"Those bastards!"
Totally awesome.
So the rest of the weekend? Anime watching, house party, work, and a picnic with Mag.
Medical Deputy #1: You know, Fred, if you keep your sense of humor like you do, you just might make it.
Fred: Make it? Make what? The team? The chick? Make good? Make do? Make out? Make sense? Make money? Make time? Define your terms. The Latin for 'make' is facere, which always reminds me of fuckere, which is Latin for 'to fuck', and I have been getting jack shit in that department as of late.

Who the **** is this autobot?
Ok so last few days have been nothing more but more programming..... oh well..... at least I'm getting into Etherscope now that some good old charcetr gen has been done.... some classic concepts.
Inspired to write some short story stuff for it!
ok another video I think....
Queue Gundams and J-rock

Another ghost story
Thomas Vaughan
Location: Kington (Hereford & Worchester) - Church
Type: Haunting Manifestation
Date / Time: 1469
Further Comments: After being killed in the battle of Banbury, Vaughan's spirit was reluctant to depart this plane of existence and tried to hide in this local church. It was finally trapped in a snuff box by the local holy men and banished into a pool.

Ghostbuster...just down the raod
Location: Manchester - Parsonage Road, Withington
Type: Haunting Manifestation
Date / Time: Unknown
Further Comments: This entity is said to have emerged from an old disused house on the corner of Parsonage Road and Swinbourne Grove and give chase to a couple of passers-by.

Royale... with the works...
There was this weekend just gone my aunts wedding. It was ok save for having to franternise with certain cousins (oh didn't you have some one to bring with you??? No... not currently.... fuckers!) and of course aunts and uncles who lets just put it this way are quite shocked by my mere presence and have no clue as to what i do for a living..... at least those uncles that are married into the family are into being civil, as they too feellike outsiders... this bloody family is just fucked.
So with alcohol taken on and myself, mother, father and sister departing before the after party (though those on the grooms side were far better to talk to) I then spent the evening drinking with an old school mate catching up on what others from school are doing. Some have bred and stayed in the town. Others have been to uni and then come back. Most have left the hole in the world known as Kington. I don't blame them.
So Returning on Sunday and out drinking with cyberai_dan, trashkitty, stacey and John a good calm evening of drinking and planning for the rest of the week ensued.
Monday.
Running round like a headless chicken passing a mic round for doctors to comment on presentations at the 135th Faraday Discussion. Joy. Though at least this means free food for the next few days and getting to see Richard Bader (the previous mentor of my supervisor and founder of one of the most important theories and methods for Quantum Chemistry in the last 30 years).
Of course Monday was roleplay night, thus a mad french man possesed me for a few hours and revelry began in copious amounts.
So what does the rest of the week hold..... ummm.... maybe Torture Gardens..... well that was cyberai_dan's idea. Maybe just a simpler weekend???? I dunno..... suggestions?
I'm off to read a paper for tomorrow, and finish hoovering (yeah.... its that fun here... totally too tired to think).
