What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.

Predictions for 2012:

RATE THIS! +1
Posted in Science on 6th Jan, 2012 07:22 PM by APM

in the beginning of the beginning, the exploding hot universe was full of elementary particles, but the particles had no mass. The universe also contained force fields, and one of those fields, the Higgs, cooled and condensed into a quantum liquid. The liquid dragged on the other particles, giving them mass. The liquid rippled, and the ripples formed a new particle, called the Higgs.

 

It reads like a just-so story. But it’s the basis of the Standard Model of physics. And so far, physicists have found every particle the Standard Model has predicted but one: the Higgs itself. Researchers at the Large Hadron Collider in Switzerland have been looking for the Higgs for more than a year, and by next winter they will either have found it or they’ll know they won’t. “It’s not obvious,” says Andrei Gritsan, a Johns Hopkins University physicist working at the LHC, “which scenario would be more interesting.”

 

Physicists at the LHC look for Higgs particles by smashing other particles into each other so hard that something like a Higgs will appear out of the energy of the collision, leaving its signature in a detector. Previous experiments have suggested that the Higgs does not “live” at energies between 0 and 114 gigaelectron-volts, and physicists have now determined that 145 GeV is the uppermost limit, so they are running out of places to look.

 

As they collide more and more particles, and detect more and more promising signatures, physicists will become increasingly sure that they’ve detected a Higgs. By this summer, they will be 95 percent confident, but for physicists that’s not good enough. By the end of this year, they will be dead certain one way or the other.
