Query: Observing GRBs with TMT   The Thirty-Meter Telescope is an ambitious project to build a giant segmented
mirror telescope with fully integrated adaptive optics systems that will
produce diffraction-limited images. A powerful suite of instruments is being
developed that, coupled with the ability to rapidly switch between targets and
instruments, will allow TMT to take advantage of GRBs to probe fundamental
physics in extreme conditions and as the ultimate tomographic beacons,
especially if some are as far as z ~ 10. This article gives a brief summary of
TMT and its instruments, and some examples of the potential offered by
observation of GRBs.
