Construction needs cloud flexibility

Australia’s embattled construction sector could benefit from cloud based information systems that can be switched on and off in lockstep with individual projects – with the exception of those organisations based in remote areas like the Kimberleys.

Large Hadron Collider looks at birth of universe

Science - Energy

CERN has announced that experiments involving the Large Hadron Collider (LHC), the world's largest and highest-energy particle accelerator, have produced new information about matter existing at the moments when the Universe was first created.

 


The European Organization for Nuclear Research, better known as CERN, has conducted experiments involving ALICE, ATLAS, and CMS.

ALICE is short for 'A Large Ion Collider Experiment', while ATLAS is an abbreviation for 'A Toroidal LHC ApparatuS' and CMS for 'Compact Muon Solenoid.'

These experiments have involved heavy ion collisions involving lead (Pb) in an action known as jet quenching.

When heavy ions are collided at extremely high energies (such as those produced by the Large Hadron Collider), a loss of energy of the 'jet' results, what scientists call "jet quenching".

A jet is defined as a narrow cone of particles (such as hadrons, or quarks held together by the strong force) that is produced in a heavy ion experiment.

Two familiar types of hadrons are protons and neutrons.

The results have produced matter that simulates the matter present at the very first moments of our primordial universe.
