These new mathematical ideas were the basis for such concepts as the general relativity of a century ago and the string theory of today. The adjective “Euclidean” is supposed to conjure up an attitude or outlook rather than anything more specific: the course is not a course on the Elements but a wide-ranging and (we hope) interesting introduction to a selection of topics in synthetic plane geometry… Links are outlined in red: clicking on them moves you to the point indicated. Non-Euclidean Geometry is now recognized as an important branch of Mathe-matics. An Introduction to Non-Euclidean Geometry covers some introductory topics related to non-Euclidian geometry, including hyperbolic and elliptic geometries. Class Syllabus . Most believe that he was a student of Plato. Good expository introductions to non-Euclidean geometry in book form are easy to obtain, with a fairly small investment. An Introduction to Non-Euclidean Geometry covers some introductory topics related to non-Euclidian geometry, including hyperbolic and elliptic geometries. In non-Euclidean geometry, the concept corresponding to a line is a curve called a geodesic. ment of the euclidean geometry is clearly shown; for example, it is shown that the whole of the euclidean geometry may be developed without the use of the axiom of continuity; the signifi-cance of Desargues’s theorem, as a condition that a given plane geometry may be regarded as a part of a geometry … The system of axioms here used is decidedly more cumbersome than some others, but leads to the desired goal.
