RECOMENDED BOOKS:
great introductory texts:
“Relativity Visualized” by Lewis Carroll Epstein https://www.amazon.com/Relativity-Exp...
There’s also this PDF that takes Epstein’s diagrams into more detail: http://www.relativity.li/uploads/pdf/...
“Relativity Simply Explained” by Martin Gardener https://www.amazon.com/Relativity-Exp...
great intro to the math of general relativity:
“A Most Incomprehensible Thing: Notes Towards a Very Gentle Introduction to the Mathematics of Relativity” by Peter Collier https://www.amazon.com/Most-Incompreh...
Requires some background in relevant math topics (see above) but very very good:
“Spacetime And Geometry: An Introduction To General Relativity” by Sean Carrol https://www.amazon.com/gp/product/933...
