This is a summary of the lectures presented at the Xth Brazilian school oncosmology and gravitation. The style of the text is that of a lightly writtendescriptive summary of ideas with almost no formulas, with pointers to theliterature. We hope this style can encourage new people to take a look intothese results. We discuss the variables that Ashtekar introduced 18 years agothat gave rise to new momentum in this field, the loop representation, spinnetworks, measures in the space of connections modulo gauge transformations,the Hamiltonian constraint, application to cosmology and the connection withpotentially observable effects in gamma-ray bursts and conclude with adiscussion of consistent discretizations of general relativity on the lattice.Comment: 13 pages, RevTeX, one figures, to appear in Proceedings of the Xth  Brazilian School on Cosmology and Gravitation, Mario Novello, edito
