Women in Physics, 2000 Highlights
By Rachel Ivie AIP Publication Number R-430 June, 2000 Katie Stowe Women in Physics, 2000 Highlights • An increasingly large number of girls have some exposure to physics by taking it in high school. By 1997, almost one-half of high school physics students were girls (Figure 1) . About 400,000 girls take high school physics each year. • Women’s participation in physics decreases with each step up the academic ladder. For example, more than two-fifths of high school physics students in 1993 were girls, but women earned less than one-fifth of bachelor’s degrees in physics five years later (Figures 1 and 3) . • Although women now earn more than one half of all bachelor’s degrees in the U.S., physics is not attracting women as quickly as other fields, including life sciences, chemistry, and engineering (Figures 4 and 5) . Compared to other fields, women are sorely underrepresented in physics at both the bachelor’s and PhD levels (Figures 4, 5, 6, 7, and Table 1) . • Twenty U.S. physics departments (excluding women’s colleges) had more than 40% female bachelor’s degree recipients during the five academic years 1994-98. This report lists these departments as well as women’s colleges that grant bachelor’s degrees in physics (Tables 2 and 3) . • The proportion of women teaching physics decreases as academic rank and level of the department increases (Table 4) . However, the percentage of women faculty members at each rank is at least as high as the percentage of women earning PhDs at various points in the past. -

Physics in Your Future Introduces Physics and Careers in Physics to Young People, Their Parents, Teachers and Advisors
TM American Physical Society • Committee on the Status of Women in Physics Chiara La Tessa of Brookhaven National Laboratory is inside the target room of the NASA Space Radiation Laboratory at Brookhaven. She is aligning a detector called EGG counter in the center of a beam – something that’s done before each experiment. Physics helps us understand the world around us, the world inside us, and the world beyond us. Physics is the most basic and fundamental science; it deals with how and why matter and energy act as they do. The laws of physics apply to force and motion, gravity, electricity, magnetism, sound, light and heat. They help us understand the physical world and develop products that people need. Mastering physics is fun and challenging. It involves working with others, as well as alone. You learn how to solve problems, observe things carefully, make measurements and keep accurate records. You can use these valuable skills for the rest of your life. They open doors to many good jobs. Physicists ask questions about the physical world and try to find exact answers. They are creative and persistent. Some do basic research. Their goal is to increase our knowledge of the universe. Others do applied research. They use basic knowledge to solve world problems such as food and energy supply, environmental protection, transportation, communication and defense. Physicists work in industry, educational institutions, government, and medical centers today. Most are active scientists and engineers. They do research and development, administration, and teaching. Others use their physics background in fields like publishing, sales, law, accounting and medicine. -

Physique Nucléaire Et De L'instrumentation Associée Introduction
FR0108546 # DEA-DAPNIA-RA-1997-98 A il. ..33/04 -DSM Département d'Astrophysique, de physique des Particules, de physique Nucléaire et de l'Instrumentation Associée Introduction Motivés par la curiosité pour les connaissances fondamentales et soutenus par des investissements impor- tants, les chercheurs du vingtième siècle ont fait des découvertes scientifiques considérables, sources de retombées économiques fructueuses. Une recherche ambitieuse doit se poursuivre. Organisé pour déve- lopper les grands programmes pour le nucléaire et par le nucléaire, le CEA est bien armé pour concevoir et mettre au point les instruments destinés à explorer, en coopération avec les autres organismes de recherche, les confins de l'infiniment petit et ceux de l'infinimenf grand. La recherche fondamentale évolue et par essence ne doit pas avoir de frontières. Le Département d'astrophysique, de physique des particules, de physique nucléaire et de l'instrumentation associée (Dapnia) a été créé pour abolir les cloisons entre la physique nucléaire, la physique des particules et l'as- trophysique, tout en resserrant les liens entre physiciens, ingénieurs et techniciens au sein de la Direction des sciences de la matière (DSM). Le Dapnia est unique par sa pluridisciplinarité. Ce regroupement a permis de lancer des expériences se situant aux frontières de ces disciplines tout en favorisant de nou- velles orientations et les choix vers les programmes les plus prometteurs. Tout en bénéficiant de l'expertise d'autres départements du CEA, la recherche au Dapnia se fait princi- palement au sein de collaborations nationales et internationales. Les équipes du Dapnia, de I'IN2P3 (Institut national de physique nucléaire et de physique des particules) et de l'Insu (Institut national des sciences de l'Univers) se retrouvent dans de nombreuses grandes collaborations internationales, chacun apportant ses compétences spécifiques afin de renforcer l'impact de nos contributions. -

To tell, we need to compare the velocity we measure on nearby galaxies to ones at very high redshift. In other words, we need to extend Hubble’s velocity vs distance plot to much greater distances. Nobel Prize Press Release The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2006 jointly to John C. Mather, NASA Goddard Space Flight Center, Greenbelt, MD, USA, and George F.
