The following year he moved to the Ford Scientific Research Laboratory, in Dearborn, Michigan, where he rose to head the departments of chemistry and chemical engineering. In 1980 he joined JPL’s Energy & Technology Applications branch; in 1982 he became JPL’s chief technologist, and he was instrumental in establishing JPL’s Microdevices Laboratory and its Center for Space Microelectronic Technology.

Ellis M.T. Dova GENEVA 2006 CERN–290 copies printed–December 2006 Abstract The CERN–CLAF School of High-Energy Physics is intended to give young physicists an introduction to the theoretical aspects of recent advances in elementary particle physics. These proceedings contain lectures on field theory and the Standard Model, quantum chromodynamics, CP violation and flavour physics, as well as reports on cosmic rays, the Pierre Auger Project, instrumentation, and trigger and data-acquisition systems. iii Preface The third in the new series of Latin American Schools of High-Energy Physics took place in Malargüe, lo- cated in the south-east of the Province of Mendoza in Argentina, from 27 February to 12 March 2005. It was organized jointly by CERN and CLAF (Centro Latino Americano de Física), and with the strong support of CONICET (Consejo Nacional de Investigaciones Científicas y Técnicas). Fifty-four students coming from eleven different countries attended the School. While most of the students stayed in Hotel Rio Grande, a few students and the Staff stayed at Microtel situated close by. However, all the participants ate their meals to- gether at Hotel Rio Grande. According to the tradition of the School the students shared twin rooms mixing nationalities and in particular Europeans together with Latin Americans. María Teresa Dova from La Plata University was the local director for the School.

Allison Physics at the University of Chicago has a remarkable history. From Albert Michelson, appointed by our first president William Rainey Harper as the founding head of the physics department and subsequently the first American to win a Nobel Prize in the sciences, through the mid-20th century work led by Enrico Fermi, and onto the extraordinary work being done in the department today, the department has been a constant source of imagination, discovery, and scientific transformation. In both its research and its education at all levels, the Department of Physics instantiates the highest aspirations and values of the University of Chicago. Robert J. Zimmer President, University of Chicago Welcome to the inaugural issue of Chicago Physics! We are proud to present the first issue of Chicago Physics – an annual newsletter that we hope will keep you connected with the Department of Physics at the University of Chicago. This newsletter will introduce to you some of our students, postdocs and staff as well as new members of our faculty. We will share with you good news about successes and recognition and also convey the sad news about the passing of members of our community. You will learn about the ongoing research activities in the Department and about events that took place in the previous year. We hope that you will become involved in the upcoming events that will be announced.

Craig Wheeler, [email protected] Astrozone and K12 Educator Two interesting years go by very rapidly. This is my last newsletter article as President. Reception My thanks to all of you who have commented positively on them for your support and to those of you who did not feel so moved on your discretion. 6-9 My term ends with a bang rather than a whimper with the sudden resignation of Alan Stern and Scenes from the the return to the NASA Science Mission Directorate of old hand Ed Weiler. Reading between the lines, my take on this transition is that Alan was dedicated to doing more with a fixed Austin Meeting budget. An important boundary condition is that he could not allow cost growth in missions. His approach to this was one of tough love. He intended to first say “no.” Any mission with 17 a threat of overrun had to find its own way of solving that problem by downscoping or delay. If, in especially pressing circumstances, the damage could not be contained in the mission, Honored Alan intended to keep it in the division. No bleeding of planetary problems into astrophysics, Elsewhere nor vice versa. I think what happened is that Alan foresaw overruns coming down the pike for which various pressures beyond his control would not allow him to exercise this tough love. It was thus a matter of principle for him to resign. He did so, by his own statement, with 19 respect for the NASA Administrator and for the team he had assembled.
