Abstract: Neutrinos have been described as the smallest amount of reality ever imagined by a human being. At energies above a TeV, however, neutrinos are arguably the most promising probe of astrophysical accelerators because of their pointing accuracy and ability to travel over cosmological distances without loosing energy. Speculative hadronic acceleration sites include Gamma-ray Bursts, Active Galaxies, Pulsars and Supernova remnants. I will give an overview of the neutrino-telescope concept and scale based on existing flux bounds. Then I will review the published AMANDA results related to Astrophysical Neutrinos including the diffuse flux limit, the point source search, and the flux limit from likely hadronic accelerators (Known AGN, pulsars, and GRB).
