On the possibility of unifying the electromagnetic and the gravitational fields
Abstract
This is the first paper by Gunnar Nordstr\"om (1881--1923) on his five dimensional theory. In his summary he states: ''It is shown, that a unifying treatment of the electromagnetic and gravitational fields is possible, if one considers the four dimensional spacetime world to be a surface in a five dimensional world.'' This paper was followed by two other papers written by the Gunnar Nordstr\"om during the one year period 1914--1915, on the same subject, which are also made available here.
