19161026Leipzig: Barth 1916. 1st Edition. FIRST EDITION OFFPRINT IN ORIGINAL PAPER WRAPS OF THE FIRST SOLUTION OF EINSTEIN'S EQUATION FOR THE METRIC OF A CHARGED POINT MASS. Überreicht vom Verfasser' Presented by the Author appears in print on the front wrap. Hans Jacob Reissner a German aeronautical engineer with a passion for mathematical physics solves Einstein's equation for an electrically charged rotating axially symmetric body. <br /> <br /> "In 1915 Einstein completed his general theory of relativity. It did not take long before the first non-trivial exact solution for the Einstein field equations was found by Karl Schwarzschild in 1916 which corresponds to the gravitational field of a spherically symmetric object" Nordebo The Reissner-Nordström Metric 3. Soon after Schwarzschild's finding Reissner in 1916 and in this paper generalized Schwarzschild's solution to include an electrically charged object. In 1918 Gunnar Nordström a Finnish theoretical physicist "independently developed what is now called the Reissner-Nordström metric or solution -- a static solution to the Einstein field equations corresponding to the gravitational field of a charged nonrotating spherically symmetric body" ibid. <br /> <br /> With perfect mathematical precision the Reissner-Nordström solution describes the spacetime geometry around a spherically non-rotating charged body -- "the spherically symmetric static exterior field of a charged distribution of mass" ibid; Stephani Relativity 199. Still "nobody understood the physical meaning of Reissner's and Nordström's solution until l1960 when two of John Wheeler's students John Graves and Dieter Brill discovered that it describes a charged black hole" Thorne Black Holes & Time Warps.<br /> <br /> The work of Graves and Brill "showed that because of the charge the Reissner-Nordström solution describes black holes with two horizons one at the Schwarzschild radius and the second being a "Cauchy horizon." It is speculated by some that such black holes if they existed would have the ability to disappear and explode into another universe" History of Physics: The Wenner Collection.

Für Jacob Ludwig Karl Grimm 1785-1863 war die wichtigste Frage "ob wir die Sprache als ein Erschaffenes oder Unerschaffenes ansehen können. Ist die Sprache von Gott erschaffen worden ist ihr erster Ursprung für uns völlig undurchschaubar. Ist sie aber unerschaffen durch den Menschen selbst gebildet worden dann kann man sich auch als Sprachforscher mit dieser Frage auseinandersetzen." unknown
