Abstract
We present a unified description of temperature and entropy in spaces with either `true' or `accelerated observer' horizons: In their (higher-dimensional) global embedding Minkowski geometries, the relevant detectors have constant accelerations ; associated with their Rindler horizons are temperature and entropy equal to 1/4 of the horizon area. Both quantities agree with those calculated in the original curved spaces. As one example of this equivalence, we obtain the temperature and entropy of Schwarzschild geometry from its flat D=6 embedding.Keywords
