“the grand design” tells you physics as cute as a fairy tale! 
sure, i lied. 

the truth is, even people said that stephen hawking could simplify physics as simple as a deluxe cheese pizza with this book, there are still lots of things behind i cannot understand. there are still a lot of theories that mesmerized me till now. this is not a light book that you could read during your tea time. you need your glasses and marker in case you have to recall the law. but, i can say as an engineering student, read what you used to solve is some kind of pleasure. thank god there are no exercises in the end of the chapters.
this review is based on the reader. if you find out that this book is bored, well congratulations, you are smarter than me.
