[PAR] [TLE] Nathan Rosen [SEP] Nathan Rosen (Hebrew: נתן רוזן; March 22, 1909 – December 18, 1995) was an American-Israeli physicist noted for his study on the structure of the hydrogen atom and his work with Albert Einstein and Boris Podolsky on entangled wave functions and the EPR paradox.  The Einstein–Rosen bridge, later named the wormhole, was a theory of Nathan Rosen. [PAR] [TLE] Einstein–Rosen metric [SEP] The Einstein–Rosen metric is an exact solution of Einstein's field equation.  It was derived by Albert Einstein and Nathan Rosen in 1937.  It is the first exact solution of Einstein's equation that described the propagation of a gravitational wave.
