# Göttingen’s academy publishes Disquisitiones generales circa superficies curvas Date: 1827 ## The fact In 1827 the Göttingen academy issued [Gauss](/people/carl-friedrich-gauss)’s Disquisitiones generales circa superficies curvas, the memoir whose Theorema egregium showed that Gaussian curvature is invariant under bending, an intrinsic fact of the surface. It is not a relativity paper and not a later classroom nickname. He wrote the Latin; the academy manufactured the issue. The row stores one memoir. It does not twin every formula in it. ## Context Surveying a curved earth forces a theory of surfaces. Gauss turned that shop problem into a public theorem: you can know curvature from measurements on the surface itself. That is education — a copyable geometric fact — not a claim that 1827 already contains Einstein, Riemann’s 1854 lecture, or GPS. Do not treat later ‘Gaussian curvature’ T-shirts as this issue. Do not treat the cadastral fiscal path of the same survey as this theorem. Riemann was a later Göttingen student after Gauss’s death in spirit of the school; he is not a co-author of 1827. Intrinsic curvature is a copyable lesson; it is not Einstein, not GPS, and not the 1829 withheld parallel-postulate book. If a number is not in the two records named above, it is not supplied here. ## Evidence and sources The Göttingen academy is the issuing house of the 1827 memoir. Stanford’s nineteenth-century geometry entry independently treats Gauss’s surface theory and the Theorema egregium as a dated turning point. Official: https://www.adw-goe.de/. Independent: https://plato.stanford.edu/entries/geometry-19th/. The records establish 1827 publication and the intrinsic-curvature claim. They do not establish a unique later physics citation series as this act. A contradictory academy year would change the row. Official or archival record: Göttingen Academy of Sciences and Humanities (https://www.adw-goe.de/; Akademie der Wissenschaften zu Göttingen). ## Significance Improving education path: a new public geometric theorem. High confidence on 1827. Modest-to-medium weight because the theorem structured a field, still not a ministry syllabus. Later relativity is reception and other authors. Held-back non-Euclidean ideas are a worsening knowledge path on another row, not this memoir. Writers/scientists: modest weights; do not nail a modern GR dataset to 1827. Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts. ## What is established and what is not Established: the 1827 academy memoir published the Theorema egregium. Not established: that Riemann or Einstein co-signed it, or that a later textbook is this issue. A showing that the theorem first appeared in another author’s 1827 book would change the row. The attached driver is edu-[digital-learning-access](/drivers/edu-digital-learning-access). The welfare reading used in this dossier is improving. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path, not hidden in adjectives. Theorema egregium is not Einstein and not a later museum plaque. Mixed effects of Göttingen’s academy publishes Disquisitiones generales circa superficies curvas are separate paths. Shared responsibility is part of Göttingen’s academy publishes Disquisitiones generales circa superficies curvas. Naming Carl Friedrich Gauss does not delete co-authors, institutions, or later transmitters. The lag from 1827-10-08 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them. ## People - Carl Friedrich Gauss: https://factrail.ai/people/carl-friedrich-gauss ## Drivers - Digital Learning Access: https://factrail.ai/drivers/edu-digital-learning-access ## Sources - https://plato.stanford.edu/entries/geometry-19th/ - https://www.adw-goe.de/ ## Methodology https://factrail.ai/methodology Canonical: https://factrail.ai/facts/gs-theorema-egregium-1827
