Naturwissenschaften – Erster Separatdruck und erster Sonderabdruck zweier Aufsätze Einsteins zur Allgemeinen Relativitätstheorie. - Boni, 109 u. 140. - Einstein Papers 7, 9. - Shields/Schilpp 118 u. 174. - Weil 99 u. 131. - Einstein Encyclopaedia, S. 300. - 1. "Einstein (in the present 1918 paper) answers criticisms of his conservation law in general relativity and the pseudotensor used to express it (first expressed in »Hamiltonsche Prinzip und allgemeine Relativitatstheorie« (1916). He argues that an integral form of the law is appropriate, and shows that the integral of a closed system's total energy is invariant and conserved and can be measured only far from the source. The pseudotensor played the key role in his analysis of gravitational waves." (Einstein Encyclopaedia) - 2. In der vorliegenden Abhandlung von 1923 räumte Einstein ein, dass seine Behauptung einer "kosmologischen Konstante" im Jahr 1917, in welcher er ein statisches Universum für möglich gehalten hatte, vermutlich ein Fehler gewesen sei. - Einige Seiten des Separatdrucks von 1923 mit Knickfalten, sonst sehr gut erhaltenes, unaufgeschnittenes Exemplar. - Der Sonderabdruck neuwertig.

Natural Sciences – One first journal issue and one first offprint of Einstein papers related to his General Theory of Relativity. - Boni, 109 u. 140. - Einstein Papers 7, 9. - Shields/Schilpp 118 u. 174. - Weil 99 u. 131. - Einstein Encyclopaedia, p. 300. - 1.

In the present 1923 paper Einstein accepted that his introduction of the 'cosmological constant' in 1917, in order to allow for the possibility of a static universe, may have been a mistake. - Some pages of the 1923 journal issue with some crease due to handling and reading, otherwise fine, uncut and therefore unread copy. - The offprint in mint condition.
