In the 20th century, many problems across all of physics were solved
by perturbative methods which reduced them to harmonic oscillators.
Black holes are poised to play a similar role in the 21st century.
They are at once both the simplest and the most complex objects in
the physical world. They are maximally complex in that the number of possible
microstates, or entropy, of a black hole is believed to saturate a universal bound. They are maximally simple in that, according to Einstein's theory, they are a featureless empty hole in space characterized only by mass, charge and angular momentum.
Progress over the last decade in understanding the dual quantum relation of simplicity and complexity embodied in black holes has been successfully applied to problems in string theory, the fundamental laws of nature, astronomy, condensed matter, nuclear and atomic physics. In this lecture I will describe these developments.
