Today in History – December 16, 1915 – Albert Einstein publishes the General Theory of Relativity.

General Theory of relativity is a theory of gravity. Ninety-one years ago on this day he published his mathematical formula for the theory of relativity. The theory introduced the famous concept of gravitation and inertia equivalence, which in turns asserts “gravitation as a determiner of the curvature in a space-time continuum.” It is obvious from the quote the complexity of this theorem and even to this day people have trouble grasping the concepts. His contribution of this theory has helped us better understand the fourth dimension known as time. The theory of relativity introduced concepts that changed the way we think of time and gravity, making it monumental in our history.
