Dr Alan Barr and his collaborators work with an enormous and hugely powerful particle accelerator called the Large Hadron Collider (LHC). He searches for and properties of new particles predicted by symmetries such as extra gauge symmetry, supersymmetry or extra spatial dimensions, using the LHC at the European Particle Physics Laboratory (CERN) near Geneva. He looks at the development of particle detectors.
|1||"Matters of Scale" - Complete Episode||The issues of scale are investigated – from how properties change at very small scales, to the vastness of the Universe. Includes parts 1, 2 and 3.||Pedro Ferreira, Alan Barr, Sylvia MacLain, Sonia Trigueros||09 Oct 2014|
|2||"Matters of Scale" Part 1 - Extremes of Scale||Professors Pedro Ferreira and Alan Barr explain what scale means to them, from particle physics to the visible universe. At the subatomic level, gravity has a surprisingly large effect and particles are so small that they have no size.||Alan Barr, Pedro Ferreira, Chris Lintott||08 Oct 2014|
