“Thus, the double unification given by the equivalence principle becomes a triple unification: All motions are equivalent once the effects of gravity are taken…

— Lee Smolin

“Impressed by the success of high-level mathematics in the formulation of the general theory of relativity in 1915, we find that Einstein's life-long quest…

— John D. Barrow

“In 1914, a Finnish physicist named Gunnar Nordstrom found that all you had to do to unify gravity with electromagnetism was increase the dimensions…

— Lee Smolin

“His head-snapping insight was that gravity could be defined as the curvature of spacetime, and thus it could be represented by a metric tensor.”

— Walter Isaacson

I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with…

— Brian Greene

“Scientists have been trying to unify Einstein’s Theory of Relativity and Quantum Mechanics.”

— Lee Vickers

“Now, at the outset of the twenty-first century, we stand on the verge of a new revolution. The search for a deeper theory than…

— Marcus Chown

M-theory is the unified theory Einstein was hoping to find.

— Stephen Hawking

Einstein's gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the…

— Richard P. Feynman

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.

— Roy H. Williams

The field equations and the whole history of general relativity have been complicated.

— Rainer Weiss

“His new idea was published that month in what became yet another seminal Einstein paper, “Cosmological Considerations in the General Theory of Relativity.” On…
