Public Lecture Tonight: Redefining High EnergyThis evening at 7:30 p.m., SLAC researcher Sarah Demers will present the public lecture The Large Hadron Collider: Redefining High Energy in the Panofsky Auditorium. Although the Standard Modelwhich describes the forces of natureis powerful, it is not complete. Important details like the masses of particles are not well explained, and realities as fundamental as gravity, dark matter, and dark energy are left out altogether. In tonight's public lecture, Demers will explain the gaps in the model and describe why there is hope that some puzzles will be solved with the Large Hadron Collider. Beginning next year, this machine will accelerate protons to record energies, hurling them around a 27 kilometer ring before colliding them 40 million times per second. Detectors the size of five-story buildings will record the debris of these collisions. The new energy frontier made accessible by the Large Hadron Collider will allow thousands of physicists to explore nature's fundamental forces and particles from a fantastic vantage point. |

Fire Safety at SLAC
|
Limited Recreational Access Along LinacWith the past week's sunny weather, SLAC security officers have received numerous reports of pedestrians walking on North Gallery Road past Sector 21-2. This road, which runs down the North side of the linac, is accessible to non-vehicular traffic only from Sector 30 to Sector 21-2. Non-vehicular traffic traveling along the linac should branch off onto Access Road at Sector 21-2. In addition, South Gallery Road is reserved solely for vehicular traffic. "South Gallery Road is narrow, making it unsafe for both vehicles and pedestrians to pass," said Simon Ovrahim, SLAC's new Head of Security. "For safety reasons, we ask everyone to obey the posted signs." Tony Chan Visits SLACTony Chan, the Assistant Director for Mathematics and Physical Sciences at the National Science Foundation, toured the lab yesterday after meeting with Jonathan Dorfan, Persis Drell, Philip Bucksbaum, Roger Blandford, Jo Stohr, and Neil Calder. Keeping to the arranged tour schedule was a challenge, as at each stop Chan asked question after question, with obvious fascination, to learn as much as possible. "It's great to be able to meet people and see the installations," Chan said. "Visiting labs is so important." Safety SecondsForty-five years ago I was taught to not talk; to not have on the radio; (both of those are the sterile cockpit rule); to constantly scan all around me; and to anticipate what might go wrong and make sure I could avoid it (situational awareness). I was learning to drive (barefoot, of course) from a retired police officer in Hawaii, and boy was he both thorough and serious. I taught my kids to drive the same way (with limited success no doubt). |
