The Quest for Gravity Wave B-modes
  One of the most exciting quests in all of contemporary science is to find
hints that in the first tiny fraction of a second after the Big-Bang the
Universe hyper-inflated by a factor of \sim 10^{60}. Such inflation will have
injected gravity waves into the fabric of spacetime which will in turn have
left a faint imprint in the polarization pattern of the Cosmic Microwave
Background. This paper describes the history of polarization measurement, the
experimental optimization of this latest search for the gravity wave imprint,
and the current round of experiments and their various approaches to the
challenge.
