This pocket sized book details 51 amazing concepts about the size of the universe, evolution, the small bits inside an atom and loads more. If you don't think this sort of stuff is interesting you might be the best person to buy this book - it will convert you. If your into science it's great for carrying around and reading on buses etc. If your wondering whether or not to buy it - it costs little more than a pint and it's only 102 pages to read (plus index etc.). If this review is badly written - it's my first, I'm just trying to say how mind blowing this book is and you should buy it.
