General Relativity Lectures by Prof. Edmund Bertschinger

Updated 3 April 2006

### Abstract: These lectures present the essential ideas of
general relativity at an advanced undergraduate level and apply
them to elementary cosmology and black hole physics.
Differential geometry is not used beyond the metric and
geodesics; a physical approach based on fields is favored over
the geometric viewpoint. The student is assumed to have had
upper-level undergraduate courses in classical mechanics, special
relativity, and electromagnetism.

## Lecture Notes 5: Cosmology
(useful for Lecture 3, 526kB)

## Recommended textbooks:

*Exploring Black Holes* by E.F. Taylor and J.A. Wheeler
(undergraduate level introduction to GR without tensor calculus)

*Gravity: An Introduction to Einstein's General Relativity*
by J.B. Hartle (advanced undergraduate level, develops tensor
calculus as needed)

*A First Course in General Relativity* by B.F. Schutz
(advanced undergraduate level, excellent introduction to tensors
and geometric concepts)
