Query: The Master never fails

This book is probably the best place to start in understanding the theory that revolutionized science. It is lucid enough for practically anyone to understand. I should know, I'm still in junior high school and I understand it. Einstein conveyed the nature of his own genius into a prose that clearly explained nearly all there is to know on the basis of modern physics. The Cosmological Supplement was, in my opinion, the most interesting part. Natural science is an amazing branch of knowledge and some even say that physics is defined as the only true science. I reccommend this book to all readers who are interested in Einstein's work and even those who don't have a clue. It is all just basic science.
