200 feet underground, a proton does 17-mile laps at nearly the speed of light. Guided by powerful magnets, it zooms through a narrow, circular tunnel that straddles the Switzerland-France border. Then a tiny adjustment in the magnetic field throws the proton into the path of another particle beam traveling just as fast in the opposite direction.
This will happen 10 million times a second inside the Atlas detector, part of the Large Hadron Collider(LHC) now under construction at CERN, the famed European particle physics lab outside Geneva. When the LHC is finished in 2007, it will be the largest accelerator in the world. Massive superconducting magnets cooled to near absolute zero by liquid helium will bend 20 micron-wide beams of protons into precise trajectories and crash them into each other.
Hadrons are a class of subatomic particles that includes protons and neutrons. When they collide, they explode into dozens of other particles, even more infinitesimal and fleeting. Atlas, five stories high and one of the most complex experimental apparatuses ever built, is designed to see them all.The cost: $3 billion and change.
Its the worlds hugest experiment and the goal is to detect the “god particle” or the atom… 3 billion dollars to detect one lousy subatomic particle

BiBo, physics is the study of how you came to be. If we didnt use science in this fashion - and experiemtn for the sake thereof, think of it - you would never know who you were. Its like a search for a name.

Which one? Atom or sub-atomic particles?
Paricle accelerator/Collider is an old concept. The only thing new here is its size.
speed barhaing with magnet ki attraction.
then takraing with another particle ya zarra.
tasadum yani takkar say kuch chotay tukray hongay.
then chotay tukray jama karing n checking keh new haain ya puranay.
agar new hain tu wah wah.
puranay hi hain tu abay yaar yeh kya hua.
on a serious note, this accelerator may give boost to string theorists. 2007 may well turn out to be the greatest year for mankind. Lets see what happens.
good one.
