Planet Libre LHC - What is the Grid? LHC Computing Grid Globe (Credit: CERN) The Large Hadron Collider (LHC) is the most powerful particle accelerator ever built. Based at the European particle physics laboratory CERN, near Geneva in Switzerland, it is the world’s largest laboratory and is dedicated to the pursuit of fundamental science. The LHC allows scientists to reproduce the conditions that existed within a billionth of a second after the Big Bang. Scientists recreate these conditions by colliding beams of high-energy protons or ions at close to the speed of light. On 4 July 2012 two of the experiments on the LHC, ATLAS and CMS, announced that they had detected a Higgs-like Boson.
Tottenham news Rafael van der Vaart claims Spurs can beat anyone ahead of trip to Manchester United on Monday Tottenham star Rafael van der Vaart has warned their Monday night opponents Manchester United: We can beat anyone right now. The Dutch midfielder sparked a 5-0 demolition of hapless Hearts in the first leg of Spurs' Europa League qualifier on Thursday night. United will obviously present a far tougher task at Old Trafford, with Sir Alex Ferguson's men battle-hardened from two tough early-season games against Manchester City and West Brom. Spurs, however, were victorious in Scotland without SIX first-team midfielders and with 21-year-old rookie Jake Livermore partnering Niko Kranjcar in the middle of the park. "We have a good squad and when we play like we did [against Hearts] we know we can win against everybody," said Van der Vaart. Jermain Defoe, Livermore, Gareth Bale and Aaron Lennon all added to Van der Vaart's opener to give Tottenham a dream start to the new season, having had their opening Premier League game against Everton cancelled because of the riots.

Based at the European particle physics laboratory CERN, near Geneva in Switzerland, it is the world’s largest laboratory and is dedicated to the pursuit of fundamental science. The LHC allows scientists to reproduce the conditions that existed within a billionth of a second after the Big Bang. This is the moment, around 14 billion years ago, when the Universe is believed to have started with an explosion of energy and matter. During this first moment of time the particles and forces that shaped our Universe came into existence. Scientists recreate these conditions by colliding beams of high-energy protons or ions at close to the speed of light. On 4 July 2012 two of the experiments on the LHC, ATLAS and CMS, announced that they had detected a Higgs-like Boson.
Cern: Higgs boson answer to come by end of 2012 | Emerging Tech Cern researchers will have established whether the Higgs boson exists by the end of 2012, according to Cern's director general Rolf Heuer. Scientists at Cern using the Large Hadron Collider (LHC) have said they will able to settle the existence of the Higgs boson by the end of 2012. Photo credit: Claudia Marcelloni/Cern The hypothetical Higgs boson is thought to be responsible for giving elementary particles their mass. "We can settle the Shakespeare question of the Higgs boson — to be or not to be — by the end of next year," Heuer told the audience at the event in Grenoble. The Higgs boson has enormous importance in the Standard Model of physics, a collection of theories about how the universe works. Physicists at Cern have established that the particle, if it exists, has a mass of between 115 and around 140 giga electron volts (GeV), according to Heuer. For the Higgs boson, we know everything about it, except if it exists. – Rolf Heuer, Cern

Large Hadron Collider results excite scientists 23 July 2011Last updated at 10:39 ET By Paul Rincon Science editor, BBC News Website, Grenoble The Atlas experiment is one of two multi-purpose experiments at the LHC The Large Hadron Collider (LHC) has picked up tantalising fluctuations which might - or might not - be hints of the sought-after Higgs boson particle. But scientists stress caution over these "excess events", because similar wrinkles have been detected before only to disappear after further analysis. Either way, if the sub-atomic particle exists it is running out of places to hide, says the head of the European Organization for Nuclear Research (Cern), which runs the LHC. He told BBC News the collider had now ruled out more of the "mass range" where the Higgs might be. The new results are based on analyses of data, gathered as the vast machine smashes beams of protons together at close to light speeds.

Sciences citoyennes Un article de Wikipédia, l'encyclopédie libre. Les sciences citoyennes sont des programmes de recherche associant des scientifiques et une participation « citoyenne » d'amateurs volontaires, d'amateurs éclairés, de spécialistes à la retraite, etc. Elles se sont notamment développées dans le domaine naturaliste, où dans le fil des sociétés savantes des siècles passés, une grande partie du travail se fait sur le terrain sans nécessiter de moyens coûteux ou de laboratoire, permettant à des non-professionnels de contribuer aux avancées en matière de connaissance et d'inventaires. Mais des objets plus lointain, astronomiques notamment font aussi l'objet de sciences citoyennes. Le document Green Paper on Citizen Science: Citizen Science for Europe les décrit dans ces termes (traduction libre) : « ... des activités de recherche scientifique auxquelles des citoyens contribuent activement par un effort intellectuel ou par l'apport de connaissances pertinentes, d'outils ou de ressources.
