20111102 OK! welcome to Iming talk. We are all keen about Amercan serials, right? For me, The big bang theory is an absolute choice. We`ve already known how funny those 4 geeks` life and how mysterious their job is. But aren`t you curious about what are the real-life physists doing now? Today we`ll talk something about the physics and its super-powered weapon in the real world. The large Hadron Collider is the device of colliding particles and collecting datas. We also use the LHC to stand for it.And the LHC`s main activity for 2011,colliding pairs of protons, came to an end as planned at the end of last month,and is switching to colliding lead ions for the next four weeks.The data produced by former experiment are starting analysing by reserchers to search for the Higgs boson and other particles.And the following collisions will produce pockets of very dense and hot matter which can recreat the conditions in the first moment after the big bang. Greg Landsberg is a physics coordinator for CMS,one of the LHC`s 2 main detectors. He said that we can get closer to the moment of big bang by the coming experiment, and the data collected from this experiment will help us with understanding what happened at the beginning of universe, and this is profound and meaningful. The experimenters hope to obtain about 10 times as much data this year compared to the LHC`s 2010 lead collisions,allowing them to investigate quark-gluon plasma in more detail and also try colliding protons with lead ions, something never done at the LHC before. And at last the LHC will shut down in early December,then switch back on in March 2012 for Proton-proton collisions. To be honest, I don`t understand what they actually do, but anyway, it sounds really cool right? I mean, those simulating-the-big-bang-condition-things sound like some sort of scene in science fiction right? Whatever, the science and technology really ran far away from people`s imagination. Our dreams in the old days are coming true. PS: material partly come from NewScience.com
