Cover: This view of the Moon's north pole is a mosaic of 18 photographs taken by Galileo as it flew by on 7 December 1992. With its ever-present black sky, the Moon offers a celestial surface with an unlimited spectral window for astronomical observations. Should telescopes be placed there? Paul Lowman Jr and Dan Lester debate the issue beginning on page 50. (Image courtesy of NASA.)

    ARTICLES

      Hunting for Jobs at Liberal Arts Colleges
      Four-year colleges offer special challenges and rewards for physics faculty. Two veterans offer advice to physicists seeking to join their ranks.
      Suzanne Amador Kane and Kenneth Laws
      pp. 38-42
      Abstract    Full Text: [ HTML   PDF (364 kB)  ]   

      Quantum Gravity Faces Reality
      String theory is only one of many approaches to quantizing general relativity. Increasingly, all those approaches will be judged by how well they accord with experimental data.
      Lee Smolin
      pp. 44-48
      Abstract    Full Text: [ HTML   PDF (860 kB)  ]   

      Build Astronomical Observatories on the Moon?
      Technological challenges, expense, and the problem of dust are among the issues to confront in any discussion of astronomy performed away from Earth. Two scientists debate the relative merits of Moon-based telescopes compared with ones in free space.
      Paul D. Lowman, Jr and Daniel F. Lester
      pp. 50-54

    SEARCH AND DISCOVERY

      Nanoelectromechanical System Approaches the Quantum Detection Limit
      Although a detector's effects on the object being measured add uncertainty to the measurement, they are not always bad. They can also cool the object.
      Richard Fitzgerald
      pp. 19-21
      Abstract    Full Text: [ HTML   PDF (310 kB)  ]   

      Collision between Galaxy Clusters Unveils Striking Evidence of Dark Matter
      The nonbaryonic matter generally assumed to dominate large aggregates of stars and gas almost always shares a common center of mass with the ordinary matter we can see. But a titanic collision can force them apart.
      Bertram Schwarzschild
      pp. 21-24
      Abstract    Full Text: [ HTML   PDF (277 kB)  ]

      Challenging Recovery for New Orleans Universities after Hurricane Devastation
      More than a year after Hurricane Katrina, New Orleans campuses are faced with smaller enrollments, reduced faculty sizes, pinched budgets–and disgruntlement about how they're handling the recovery.
      Toni Feder
      pp. 28-29
      Abstract    Full Text: [ HTML   PDF (194 kB)  ]   

      Science Board Recommends Major Hurricane Research Program
      With New Orleans and the Gulf Coast still suffering from the devastation of Hurricane Katrina, the NSB wants to reduce vulnerability to future storms through increased research.

      Abstract    Full Text: [ HTML   PDF (88 kB)  ]   

      Reactor Experiments Seek Missing Neutrino Mixing Angle
      Exposing the details of how electron neutrinos change flavor could be a step toward determining the neutrino mass hierarchy and explaining the imbalance of matter and antimatter in the universe.
      Toni Feder
      pp. 31-32
