Welcome to the bizarre and amazing world of black holes! As you will see,  the physics related to black holes  runs from scales that are essentially infinitesimally small (the black hole singularity) to one hundred times larger than the size of our entire galaxy (the jets produced by radio galaxies).  Most of the slides in this talk are taken from the Web and represent but a small smattering of what is now available to adventurous Web explorers.
	Inspiration for this talk (as well as many slides!) came from the excellent presentations of Kip Thorne and Roger Blandford at a recent teachers’ workshop on black hole astrophysics. Please see http://www.itp.ucsb.edu/online/bh_teach for more!
