Event horizons and thermodynamics

In early 1995, Ted Jacobson found an intriguing way to “localize” the relationship between the temperature and entropy on one side, and the acceleration and areas on the other side. In fact, he derived Einstein’s equations from a well-known thermodynamic equation. See also Einstein’s equations as equations of state.
