General Relativity Without Calculus
by Jose Natario
Publisher: Springer 2012
Number of pages: 120
This book was written as a guide for a one week course aimed at exceptional students in their final years of secondary education. The course was intended to provide a quick but nontrivial introduction to Einstein's general theory of relativity, in which the beauty of the interplay between geometry and physics would be apparent.
