We describe some recent work on the uses of twisted sheaves in algebra, arithmetic, and geometry. In particular, we touch on the role of twisted sheaves in: The geometry of the period-index problem for the Brauer group.The connection between finiteness of the u-invariant and Colliot-Thelene's conjecture on 0-cycles. The link between the Tate conjecture for K3 surfaces and finiteness of the set of isomorphism classes of K3 surfaces over a finite field. The geometry of rational curves on the moduli spaces of supersingular K3 surfaces.
