مكتوب بطريقة سهله جدا، مش محتاج اكتر من الرياضيات اللي المفروض انك درستها في ثانوي و في الجامعه لو فاهمهم كويس الكتاب بالنسبالك هيبقى رائع

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.

Went on holiday then returned and felt like reading other books. Will return to finish later

By far the most important scientific discovery of the last century. Newton's laws of thermodynamics, Galileo and the Copernican revolution, and Edison's/Tesla's DC/AC are alongside Einstein's Discoveries in relativity as some of the most important scientific progress of the last 500 years or so.
It would be like waking up one morning and finding out everything you knew about physical, mechanical, or classical physics was not always correct. As a matter of fact, that's exactly what happened for many scientists. Classical mechanics is correct 95% of the time, but those other 5% of times it isn't. Why?
Well, relativity plays the primary role. The Doppler effect for instance, shows how a stationary observer and a moving sound can change wavelength and frequency based on the relative distance to the observer. And relatively doesn't just affect sound. It touches just about everything. Thus, quantum mechanics is born and Einstein changed the way we use GPS systems, satellites, and most all of space travel today.

Einstein explica de forma didática a teoria da relatividade e mostra um pouco de como a física age em nossa realidade e em como ela é aplicada.
Vale a pena a leitura.
