Topic description[edit]
General relativity (GR) is an advanced topic within the department of Astrophysics and requires a high level of knowledge in calculus, algebra and physics in general. Tensor fields are a critical part of general relativity.
Prerequisites[edit]
 Topic:Special relativity (SR)  the spacetimes of GR have the spacetime of SR as a limiting case at a point in spacetime, so you must first understand SR
 Topic:Differential geometry  you need to understand tensors, tensor fields and differential geometry in general in order to understand GR; elements of these are frequently taught within a GR course as an alternative to a full differential geometry course
Courses[edit]
 Special relativity and steps towards general relativity (shortcut: SRepsilonGR)
 this course includes a few elements towards elementary general relativity
 Cosmology
 twentieth/twentyfirst cosmology is one of the main applications of general relativity
Lectures[edit]
 General relativity
 Introduction to general relativity
 Inveiling the breakdown of Euclidean geometry in linearized general relativity
Learning Projects[edit]
See: Learning Projects and the Wikiversity:Learning model.
Learning materials and learning projects can be used by multiple departments. Cooperate with other departments that use the same learning resource.
Relevant topics: Covariance, Vectors/ Fields, Tensor Calculus, EulerLagrange equations, Equivalence principle, Curvature, Riemann Tensor, Gravitational Waves
