My critique for this book lies not in the lectures themselves (which are, in my opinion, too short), but in the way this book is comprised of 50% graphics - which barely added anything to my understanding - and 30% superfluous commentary. Though I read the book as an ebook, I can imagine the formatting that it took to get the book to a state where it could be sold for 20€. This may be the popular science (or Stephen Hawking hype) curse, but I still find it rather insulting.

I really should stop making the mistake of picking up books in formats that I do not enjoy, huh?
