Q&A: The Higgs boson. 4 July 2012Last updated at 04:16 ET Six theoreticians, including the English physicist Peter Higgs, first proposed the Higgs mechanism in 1964.
Taking a closer look at LHC - PHYSICS AT LHC. Particle physics for high school students. While many students aren´t introduced to particle physics at school, the “International Hands on Particle Physics Masterclasses” offer young people between 16 and 19 years the chance to step into a researcher´s shoes. Each year in March thousands of high school students worldwide participate in this outreach programme, which is organised by EPPOG (European Particle Physics Outreach Group). Its central coordination for all participating locations, including 17 institutes in Germany, is done at TU Dresden by Michael Kobel and Uta Bilow and is a part of the outreach activities supported in the backbone programme of the Terascale Alliance. The programme turns participants into scientists for one day. They come to a nearby university or research institute, listen to lectures and work collaboratively with particle physicists, analysing real data from CERN. In an authentic setting and a stimulating environment, the scientists let students gain insight into their research.
GridPP - UK Computing for Particle Physics. This introduction answers some frequently asked questions about the Grid: What is the Grid?
Why do we need the Grid? What makes the Grid different from the Web or Internet? What is GridPP doing? Who and what is involved in GridPP? It will also discuss Grid middleware, running a Grid, Grids beyond particle physics and Gridsite, a website tool developed by GridPP. Broadcast Yourself. Welcome to YouTube!

Οδοιπορικό στο CERN « Μετα την εφημεριδα. «Οταν προσπαθώ να εξηγήσω στην οχτάχρονη κόρη μου τι δουλειά κάνω, της λέω ότι φτιάχνουμε το μεγαλύτερο μικροσκόπιο του κόσμου και να σου πω την αλήθεια είναι αρκετά ακριβές αυτό».
Περπατάω στους δρόμους του CERN, του ευρωπαϊκού οργανισμού για την πυρηνική έρευνα με τον 34χρονο Γιάννη Παπαδόπουλο, έναν από τους περίπου 20 μόνιμους ερευνητές που διαθέτει η χώρα μας σε αυτήν τη γωνιά της Γενεύης, στην Ελβετία. Πηγαίνουμε να συναντήσουμε τα υπόλοιπα μέλη της ελληνικής επιστημονικής ομάδας, που βρίσκεται εδώ στο πλαίσιο της πρώτης ξενάγησης που οργάνωσε το ερευνητικό κέντρο, ειδικά για Ελληνες δημοσιογράφους. Το αντικείμενο της συνάντησης είναι βεβαίως ο μεγάλος επιταχυντής Αδρονίων (Large Hadron Collider), ένα τεραστίου μεγέθους διεθνές ερευνητικό πρόγραμμα Σωματιδιακής Φυσικής Υψηλών Ενεργειών, που αναμένεται να τεθεί σε λειτουργία τον επόμενο Μάιο και να απαντήσει σε θεμελιώδη ερωτήματα των επιστημόνων για την σύσταση της ύλης και την ιστορία της γέννησης του Σύμπαντος.

LHC - The Particle Detectives. 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. 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.

The "Grids for Kids" initiative gives children the opportunity to learn about the Grid and to see the Grid environment in action. First held in January 2007, we have now completed several successful events. Holding your own "Grids for Kids" event has never been more rewarding.
You will need kids aged 9 to 12 teachers (for discipline, safety and follow-up enthusiastic presenters (one or two) computers connected to the Internet (enough for one between three kids) a room complete with chairs and a projector a blackboard or whiteboard sufficient pens and packets of post-it notes. E-Science - Kids inspired by Grid Computing. Wednesday 28 November 2007 Kids inspired by Grid Computing The complexities of Grid computing may seem like a barrier to explaining it to 10 and 11 year olds.
Grid computing. What is grid computing? Although "the Grid" is still just a dream... grid computing is already reality.
Imagine several million computers from all over the world, and owned by thousands of different people. Imagine they include desktops, laptops, supercomputers, data vaults, and instruments like mobile phones, meteorological sensors and telescopes... Now imagine that all of these computers can be connected to form a single, huge and super-powerful computer! This huge, sprawling, global computer is what many people dream "The Grid" will be. The pathway to inquiry based science education spic efk. ISOTDAQ - where students learn about trigger and data acquisition.
Where can students learn to implement a good trigger and to design the data acquisition system for today’s increasingly complex experiments?
Universities rarely include classes on such specific topics. The ISOTDAQ School trains students and helps them gain hands-on experience of trigger systems, data-acquisition hardware and software, and data-transfer technologies. One of the commercially available FPGA development boards from Altera. This was used in one of the practical exercises at ISOTDAQ2011 to teach students the principles of FPGA programming. The second International School of Trigger and Data Acquisition (ISOTDAQ) was held from 9 to 16 February at the Physics Department of Rome University, ‘La Sapienza’.
“Leading experts in the field gave lectures on various topics, such as trigger systems, data-acquisition hardware and software, and data-transfer technologies,” explains the organiser, Enrico Pasqualucci, an INFN researcher and the ATLAS Muon DAQ Coordinator. By CERN Bulletin. LHC computing grid pushes petabytes of data, beats expectations. The LHC isn't simply the most powerful particle accelerator ever created.
Handling the huge amounts of data it produces has required the creation of one of the biggest computer grids on the planet. The planning and testing of the compute facilities has been taking place for years, but it's only recently that the grid has had to deal with the output from actual collisions. How did it do? "From the IT perspective, we didn't notice when the beams came on," said CERN's Wolfgang von Rueden, "We had tested it with much higher throughput conditions. " Still, not everything is working quite according to plan. von Rueden said that the initial expectations for the LHC's computing grid had anticipated lower network performance and a reliance on tape; instead, the network has made it easier to shuffle large data sets between compute centers, and the price and performance of hard drives have turned out better than expected. Openlab Reports. CERN needs to define approaches for achieving the dual goals of connecting its operational network to the Internet while at the same time keeping its industrial control systems secure from external and internal attacks.
With this in mind, the ISA-99 international cyber security standard was adopted as a reference model to define a set of implementation guidelines and a list of security robustness criteria applicable to any network device. Device security represents a key link in the defense-in-depth concept (See Figure ISA reference model for the Distributed Control Systems), as some attacks will inevitably penetrate security boundaries and thus require further protection measures.
Since no solutions based on security standards are available on the market, a wide investigation of the current cyber security testing techniques and systems has been performed in the first phase of the project.
