1. EJECTORS, ACCRETORS, BURSTERS, AND FLARES
This category of projects is devoted to understanding high energy accreting or jetted astrophysical sources such as active galactic nuclei (AGN), Galactic microquasars, gamma-ray bursts (GRB), solar flares, and planetary nebulae. These sources are magnetized, exhibit outflows and efficient particle acceleration, and require turbulence. The physics of particle acceleration, accretion disks, and high energy plasmas are important for these studies.
2. ORIGIN AND DYNAMICS OF MAGNETIC FIELDS
This category of projects focues on a rigorous understanding of the the orgin and dynamics of astrophysical magnetic fields and the associated MHD turbulence. Magnetic fields are not only fundamental for their dynamical role as an intermediary between gravitational energy and radiation in many sources, but are observable astrophysical entities themselves, detected by a variety of techniques. See the following figure (from ApJ 584 L99 (2003). ) which encapsulates some recent progress (e.g. Phys. Rev. Lett., 89, 265007 (2002)) of how magnetic dynamos conserve magnetic helicity. Some of the underlying MHD physics also has application to magnetic pinch configurations in laboratory plasma configurations of fusion devices. I am now directing attention toward these applications.
3. FORMATION OF ASTROPHYSICAL OBJECTS
Recently, I have been involved in projects in planet formation and star formation

Pictures of Insight on Facebook
Audio recording of Insight speaking for 25 minutes on his play gym alone in the kitchen early in the morning (August 2009). (video showing him at his play gym on another ocassion to show his location) , and comments and transcript of the first half.

The playists below include ~1000 selections from YouTube of mostly 1950s and 1960s doo-wop (with some Jazz and newer R&B mixed in, mainly in volume 1). I've largely avoided the most famous commonly played selections and have aimed for more obscure gems. I've liked doowop since I was a small child. It's primarily vocal music, originating from a cappella groups on street corners in urban communities where the voices were the instruments. Thus the vocal harmonies are often more subtle and sophisticated than the accompanying background music.
