NOBEL FOCUS: HELIUM IMPERSONATES A SUPERCONDUCTOR
Part of this year's physics Nobel prize went to Anthony Leggett of
the University of Illinois at Urbana-Champaign for his work on
superfluid helium. A superfluid flows without any viscosity or
resistance and has other exceptional properties. In 1965 Leggett
formulated a theory of the superfluid phase in helium-3--the rare
isotope of helium--in the Physical Review. Seven years later, just
weeks after the discovery of the superfluid, he extended his
analysis in a PRL paper and precisely identified the state that was
seen in the new data. Leggett's theory has been borrowed in many
areas of physics, including models of phase transitions in the very
early universe.

FOCUS INTERNSHIP
We are seeking a roughly half-time intern for the period January-
June 2004 (hours and dates flexible). The primary duty is to write
Focus stories. We would like the intern on-site, in College Park,
MD, but a remote arrangement is also possible. Applicants must have
taken writing courses and/or written articles on science for a
general audience. For details, please respond to this message
(owner-focus@lists.apsmsgs.org).
