The physics of general relativity is developed with great care, followed by an introduction to the usual formalism and some more advanced topics.

*cite book | author=Schutz, Bernard F.| title=Gravity from the ground up| publisher=Cambridge University Press| year=2003 | id=ISBN 0-521-45506-5 A more elementary treatment than Rindler's, this book uses no more than a little algebra and trigonometry to explore Einstein's theory of gravity. A good book to develop an intuitive understanding of general relativity, underpinned by helpful back-of-the-envelope type calculations.
