Visualizing Quantum Loop Gravity

Just one of the things that supercolliders such as CERN's Large Hadron Collider and Fermilab's Tevatron might find is evidence for something called "Quantum Gravity Loops"—which theoreticians say could explain a lot about the force known as gravity.

What could such things look like?

To try to illustrate the concept, the Max Planck Institute for Gravitational Physics made the accompanying movie, "Quantum Spin Dynamics in Loop Quantum Gravity." It depicts the quantum evolution of geometry in Loop Quantum Gravity, with the colors of the faces of the tetrahedrals indicating where and how much area exists at any given moment.

It's also pretty cool to watch!  See the video on ISGTW...

SLUO Annual Meeting Convenes Today

The SLAC Users Organization hosts the 2009 SLUO Annual Meeting today, from 8:30 a.m until 6:30 p.m. in Kavli Auditorium, followed by a reception in the Panofsky Auditorium breezeway. The meeting provides an excellent opportunity for SLAC scientific users to learn about the vision of our agencies for funding science, the plans of the lab, and the latest developments and science opportunities in the SLAC Particle Physics and Astrophysics Directorate. It is also a great time to learn about new projects and to interact with other users and potential new colleagues, and to discuss the future collaborations between SLAC National Accelerator Laboratory and the university physics community.

Coalition Honors Representative Anna Eshoo for Commitment to U.S. Research Leadership

The Science Coalition today gave Congresswoman Anna Eshoo its "Champion of Science" award in recognition of her strong commitment and continued advocacy for basic research funding. "Representing much of Silicon Valley and several research institutions, Congresswoman Eshoo understands the significant role basic research plays both in advancing our knowledge in critical areas like health care and energy and in driving our economy," said Stanford School of Medicine Dean Philip Pizzo.

Throughout her 16-year career representing California's 14th congressional district, Representative Eshoo has worked tirelessly to promote American competitiveness and innovation. In 2005, the Congresswoman introduced the Innovation Agenda - A Commitment to Competitiveness to Keep America #1, which promoted an increased investment in research and development and the creation of the Advanced Research Projects Agency for Energy. "I know firsthand Congresswoman Eshoo's support, commitment and farsighted approach to maintaining America's leadership in basic research, and in Department of Energy research in particular. She has been a strong ally in the effort to invest in the research and development needed to secure America's energy future," said Persis Drell, director of SLAC National Accelerator Laboratory.  Read more from Eurekalert...

SLAC Green Note: Help Protect Bay Area Surface Waters

Stormwater runoff from SLAC discharges to San Francisquito Creek and eventually to San Francisco Bay.

Saturday, September 19 is the 25th Annual California Coastal Cleanup Day.

Please do your part to protect these water bodies. Keep your outdoor work and storage areas clean and orderly, properly contain small fragments such as wires, metal cuttings and plastics, store materials and equipment inside or under tarps whenever possible, and immediately report spills to SLAC Security (x5555).

For more information, refer to SLAC's Stormwater Best Management Practices and Environment, Safety and Health manual Chapter 26: Stormwater.

See also tips to help prevent storm water pollution at home and consider volunteering at a local clean up event. This Saturday, September 19, from 9 a.m. to noon, is the 25th Annual California Coastal Cleanup Day event. See the this Web page for information and a list of San Mateo County Cleanup Locations.
