The goal of the Daya Bay Reactor Antineutrino Experiment is to determine the neutrino-mixing angle, theta-13, with a precision better than 0.01 in sin^2(2theta-13). The value of sin^2(2theta-13) is measured by comparing the observed electron-antineutrino rates and energy spectra with functionally identical detectors located at various baselines from the reactors. This kind of relative measurement using a near-far configuration significantly reduces the systematic errors. Daya Bay began data taking near the end of 2011 and reported the observation of a non-zero value for theta-13 recently. In this seminar, an overview of the experiment and the latest results from Daya Bay will be presented.
