First Edition. Einstein, Albert. GEOMETRIE UND ERFAHRUNG. [Geometry and Experience] [PP.121-131]. Julius Springer, Berlin, 1921. Erweiterte Fassung des Festvortrages gehalten an der Preussischen Akademie der Wissenschaften zu Berlin am 27. Januar 1921. 8VO., 20PP. With 2 text illustrations. Original printed cream wrapper. First Edition. Weil 115. HBS52699. At 1921 at the Prussian Acedemy's commemorative session honoring Frederick the Great, founder of the Academy, Einstein delivered this lecture in which he summed up his views on the geometrization of physics and relativity and the relation of mathematics to the external world. Here he gave his famous answer to the puzzling question of why mathematics should be so well adapted to describing the external world: "Insofar as the Laws of Mathematics refer to the external world, they are not certain; and insofar as they are certain, they do not refer to reality" [D.B.S. Vol. 4, p. 330]. A fine copy. This is a mature work of Einstein, published when he was 42 years old, and in the year he received the Nobel Prize in Physics.
