Jacob Bekenstein

Born in Mexico city, Mexico born May 1, 1947


Bekenstein received his undergraduate education in Polytechnic University in Brooklyn, New York. He received his PhD from Princeton University in 1972.

Major Contribution(s) to Physics

In 1972, Bekenstein was the first to suggest that black holes should have a well-defined entropy. he also formulated the generalized second law of thermodynamics, black holes. Bkenstein

Brief Summary of the theory/research,important to Science

Based on his black-hole thermodynamics work, Bekenstein also demonstrated the Bekenstein bound: there is a maximum to the amount of information that can potentially be stored in a given finite region of space which has a finite amount of energy (which is similar to the holographic principle).

In 1982, Bekenstein was the first person to develop a rigorous framework to generalize the laws of electromagnetism to handle inconstant physical constants. His framework replaces the fine structure constant by a scalar field. However, this framework for changing constants did not incorporate gravity.

In 2004, Bekenstein greatly boosted Mordehai Milgrom’s theory of Modified Newtonian Dynamics (MOND) by developing a relativistic version. It is known as TeVeS for Tensor/Vector/Scalar and it introduces three different fields in space time to replace the one gravitational field.
