Theodore A. "Ted" Jacobson (born November 27, 1954) is an American

theoretical physicist Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain, and predict natural phenomena. This is in contrast to experimental physics, which uses experi ...

In particular, in 1995 Jacobson proved that the Einstein field equations describing relativistic gravity can be derived from thermodynamic considerations.Ted Jacobson, "Thermodynamics of Spacetime: The Einstein Equation of State", ''
