Professor Helen Quinn
Professor Helen Quinn Helen Quinn was born in Australia and grew up in the Melbourne suburbs of Blackburn and Mitcham. She attended Tintern Girls Grammar School in Ringwood East. She matriculated successfully and obtained a cadetship from the Australian Department of Meteorology to fund her studies at the University of Melbourne. After beginning her undergraduate studies at the University, her family migrated to San Francisco in the early 1960s. Professor Quinn finished her undergraduate, and eventually graduate education at Stanford University. After receiving her doctorate from Stanford in 1967, she held a postdoctoral position at Deutsches Elektronen Synchrotron in Hamburg, Germany, then served as a research fellow at Harvard in 1971, joining the faculty there in 1972. She returned to Stanford in 1976 as a visitor on a Sloan Fellowship and joined the staff at the Stanford Linear Accelerator Centre (SLAC) in 1977. In her current position as a theoretical physicist at the Stanford Linear Accelerator Center (SLAC), Professor Quinn has made important contributions towards unifying the strong, weak and electromagnetic interactions into a single coherent model of particle physics. In 2000 she was awarded the Dirac Medal and Prize for pioneering contributions to the quest for a unified theory of quarks and leptons and of the strong, weak, and electromagnetic interactions. The award, shared with Professors Howard Georgi of Harvard and Jogesh Pati of the University of Maryland, recognized Professor Quinn for her work on the unification of the three interactions, and for fundamental insights about charge-parity conservation. She has also recently developed basic analysis methods used to search for the origin of particle-antiparticle asymmetry in nature. -

Declared the World Year of Physics by the United Nations, the year provided a unique opportunity for the international physics community to reach out to the general public while celebrating the centennial of Einstein’s “miraculous year.” The year started with an international Launching Conference in Paris, France that brought together more than 500 students from around the world to interact with leading physicists. -
Long Term Planning Theme at Annual Users' Meeting

What are the tools that will answer those questions?" These and other questions were posed by Peter Rosen, Associate Director in the DOE's Office of Science, during the annual SLUO Meeting in July. Over 200 users came to SLAC from around the world for a discussion about the science and politics of high energy physics (HEP). Speaking at the meeting, SLAC Director Jonathan Dorfan and Fermilab Director Michael Witherell expressed similar sentiments. Dorfan suggested that a different planning model is needed for the new challenges facing big science. "Previously we looked at a next generation machine and we endorsed that one s facility. It would be much better for the field if we which is intended to provide an update to the HEPAP looked 20-30 years ahead and developed a roadmap for subpanel.

Friedman and Henry W. Kendall, both of the Massachusetts Institute of Technology, Cambridge, MA, USA, and RichardE. Taylor of Stanford University, Stanford, CA, USA, for their pioneering investigations concerning deep inelastic scattering of electrons on protons and bound neutrons, which have been of essential importance for the development of the quark model in particle physics.

Glossary of Terms Absorption Line a Dark Line at a Particular Wavelength Superimposed Upon a Bright, Continuous Spectrum
Glossary of terms absorption line A dark line at a particular wavelength superimposed upon a bright, continuous spectrum. Such a spectral line can be formed when electromag- netic radiation, while travelling on its way to an observer, meets a substance; if that substance can absorb energy at that particular wavelength then the observer sees an absorption line. Compare with emission line. accretion disk A disk of gas or dust orbiting a massive object such as a star, a stellar-mass black hole or an active galactic nucleus. An accretion disk plays an important role in the formation of a planetary system around a young star. An accretion disk around a supermassive black hole is thought to be the key mecha- nism powering an active galactic nucleus. active galactic nucleus (agn) A compact region at the center of a galaxy that emits vast amounts of electromagnetic radiation and fast-moving jets of particles; an agn can outshine the rest of the galaxy despite being hardly larger in volume than the Solar System. Various classes of agn exist, including quasars and Seyfert galaxies, but in each case the energy is believed to be generated as matter accretes onto a supermassive black hole. adaptive optics A technique used by large ground-based optical telescopes to remove the blurring affects caused by Earth’s atmosphere. Light from a guide star is used as a calibration source; a complicated system of software and hardware then deforms a small mirror to correct for atmospheric distortions. The mirror shape changes more quickly than the atmosphere itself fluctuates. -

Memories of a Theoretical Physicist
Memories of a Theoretical Physicist Joseph Polchinski Kavli Institute for Theoretical Physics University of California Santa Barbara, CA 93106-4030 USA Foreword: While I was dealing with a brain injury and finding it difficult to work, two friends (Derek Westen, a friend of the KITP, and Steve Shenker, with whom I was recently collaborating), suggested that a new direction might be good. Steve in particular regarded me as a good writer and suggested that I try that. I quickly took to Steve's suggestion. Having only two bodies of knowledge, myself and physics, I decided to write an autobiography about my development as a theoretical physicist. This is not written for any particular audience, but just to give myself a goal. It will probably have too much physics for a nontechnical reader, and too little for a physicist, but perhaps there with be different things for each. Parts may be tedious. But it is somewhat unique, I think, a blow-by-blow history of where I started and where I got to. Probably the target audience is theoretical physicists, especially young ones, who may enjoy comparing my struggles with their own.1 Some dis- claimers: This is based on my own memories, jogged by the arXiv and IN- SPIRE. There will surely be errors and omissions. And note the title: this is about my memories, which will be different for other people. Also, it would not be possible for me to mention all the authors whose work might intersect mine, so this should not be treated as a reference work. -
