Definition of non-Euclidean in English:
non-Euclidean
adjective nɒnjuːˈklɪdɪənˌnän yo͞oˈklidēən
Geometry Denying or going beyond Euclidean principles in geometry, especially contravening the postulate that only one line through a given point can be parallel to a given line.
Example sentencesExamples
- In 1915, Albert Einstein found it more convenient, the conventionalist would say, to develop his theory of general relativity using non-Euclidean rather than Euclidean geometry.
- A modern realist would say that what mathematicians hadn't realised is that, as well as Euclidean geometry, there also exists non-Euclidean geometry.
- Beltrami in this 1868 paper did not set out to prove the consistency of non-Euclidean geometry or the independence of the Euclidean parallel postulate.
- By chapter two he is proving Pythagoras' theorem from first principles and introducing non-Euclidean geometry.
- It can be shown that if Euclidean geometry is internally consistent, then the alternative non-Euclidean geometries are consistent as well.
