Query: Science with the Square Kilometer Array: Motivation, Key Science
  Projects, Standards and Assumptions   The Square Kilometer Array (SKA) represents the next major, and natural, step
in radio astronomical facilities, providing two orders of magnitude increase in
collecting area over existing telescopes. In a series of meetings, starting in
Groningen, the Netherlands (August 2002) and culminating in a `science retreat'
in Leiden (November 2003), the SKA International Science Advisory Committee
(ISAC), conceived of, and carried-out, a complete revision of the SKA science
case (to appear in New Astronomy Reviews). This preface includes: (i) general
introductory material, (ii) summaries of the key science programs, and (iii) a
detailed listing of standards and assumptions used in the revised science case.
