Relativity: The Special and the General Theory by Albert Einstein

4.0

It is a truth universally acknowledged, that The Theory of Relativity is demanding and it is needless to say that you need to read it more than once.

While there is a plethora of books on relativity, available in shiny covers with technicolor nebulae and stuff for your ocular pleasure, which claim to provide an easier and better understanding of the topic, they are no substitute for this succinct book by the master himself.
"Everything should be made as simple as possible, but not simpler
" - Einstein
Any simpler and you risk crossing the border between science and science-fiction.

The first part (The Special Theory of Relativity) is relativity less perplexing than second part (The General Theory of Relativity), which is a complete mind-bender. I got some help from my earlier reading of A Brief History of Time which has a very good two page summary in Chapter 2, just after the part with light-cones.
