Such fields form towers whose height grows with each twist at a velocity comparable to the circular velocity of the accretion disk that turns them. A discussion of the generation of such towers is preceded by a brief history of the idea that quasars, active galaxies, and galactic nuclei contain giant black holes with accretion disks.18 pages, LaTex (renewpasp.sty), 4 eps figuresAstrophysicsWhy Do Disks Form Jets?text
