This book makes learning about modern physics relatively easy. The writing style is engaging and clear. The book is rather short and focuses on the big picture while leaving many questions open. But this is actually a good thing because you first want to get an overview before diving into the details.<br><br>I was somewhat disappointed that even in the second edition many typos (especially in the equations) remain uncorrected.<br><br>Before reading this book, I recommend to first go through the author's No-Nonsense books (which are more elementary and detailed) or the similar Theoretical-Minimum books by Susskind.
