An LSC is illuminated by a laser beam (central spot) resulting in luminescence that is emitted from the edges and projected onto a white business card. The faintly visible concentric rings and different colors of light on the business card result from microcavity effects.

Bruce E. Logan, the Kappe professor of environmental engineering, researches the use of hydrogen as an everyday, environmentally friendly fuel source.

Moses H. W. Chan, the Evan Pugh Professor of physics.
He is distinguished in his work on phase transitions--the conditions under which a material changes from one phase to another--in quantum fluids, in reduced dimensions, and in the presence of disorder. The principles he and his research group have helped to establish have proven to be useful in understanding a wide variety of problems in condensed-matter systems undergoing phase transitions.

Researchers Henry J. Donahue, the Michael and Myrtle Baker professor of orthopaedics and rehabilitation, left, and M.D./Ph.D. student Shane Lloyd developed a bone-density experiment that will be aboard the last space shuttle mission.

This Nov. 17, 2004, handout image from NASA shows an artist's rendition of the Swift spacecraft observing a gamma burst. Swift is a first-of-its-kind, multi-wavelength observatory dedicated to the study of gamma-ray burst (GRB) science. During its nominal two-year mission, Swift is expected to observe more than 200 bursts, which will represent the most comprehensive study of GRB afterglow to date.

Examining a few of the Hemingway letters are, from left, Sandra Stelts, curator of rare books and manuscripts at the University Libraries; Sandra Spanier, Penn State professor of English and general editor of the Hemingway Letters Project; and William L. Joyce, the Dorothy Foehr Huck Chair and head of the Special Collections Library.

B. Voight examining Plymouth, the destroyed former capitol of Montserrat.

In 2002, Voight also helped organize a team of scientists to form the Caribbean Andesite Lava Island Precision Seismo-geodetic Observatory, or CALIPSO. “The acronym came into being after a very fine margarita imbibed in Washington, D.C.,” Voight notes, adding: “The name fits in all respects.” Seven years later, the Soufriere Hills volcano remains one of the world’s most closely studied stratovolcanoes.
