Exciting new observational and theoretical advances lead today's solar physicists to challenge many of the predictions of even recent models. This volume summarizes the major questions at the forefront of solar physics theory and observations, and proposes priority recommendations to explore these questions. The study also addresses serious institutional issues that have beset solar physics including the role of the universities in the national solar observations, structural barriers to careers in solar physics, and the leadership role of the federal funding agencies for ground-based solar research.
