Physics & astronomy · 1905
Ist die Trägheit eines Körpers von seinem Energieinhalt abhängig?
Annalen der Physik · 4th series · vol. 18 · 1905
Shows that a body emitting energy L as radiation loses mass L/V², so its mass measures its energy content.

Edition
German Wikisource transcription (marked “korrigiert”), made from the scan of Annalen der Physik, 4th series, vol. 18 (Leipzig: Johann Ambrosius Barth, 1905), pp. 639-641, on the Internet Archive (annalenderphysi143unkngoog) and on Wikimedia Commons (File:Einstein-Energieinhalt.djvu), checked word by word and formula by formula against that scan. Corrected against the scan: “leeren Baum” to “leeren Raum” (p. 639); the signs of (H0 - E0) - (H1 - E1), for which Wikisource has plus signs (p. 640); the full stop that ends the equation for H0 (p. 640); “Betrag,” to “Betrag.” (p. 641). The title and “von A. Einstein.” are in the header, whose byline restates in English the closing lines “Bern, September 1905. (Eingegangen 27. September 1905.)”, which stay at the end of the text; the article number “13.”, running heads, page numbers and the sheet signature “42*” are left out, and hyphens at line ends are rejoined. The two footnotes keep their numbers and follow the text. Letter-spaced names stay letter-spaced. The equations are set with KaTeX: the equations for E0 and H0, and those for H0 - E0 and H1 - E1, are each one aligned display as in the scan, the parentheses around the coordinate triples (x, y, z) are set with the letters they enclose, and the multiplication point of “9 . 10^20” keeps its spaces.
Rights
Albert Einstein died on 18 April 1955, so his works are in the public domain in France since 1 January 2026 (70 years counted from 1 January 1956). The paper was published in 1905, before 1 January 1931, so it is in the public domain in the United States.
