There's nothing instant about this book and that's a shame. It covers the whole gamut of physics, but given the size of the book, it doesn't really say a lot about each area. You get a few lines describing the topic, a lot of wasted free space, some great drawings and then lots of complicated equations. Anyone looking to learn about physics won't need to know those equations just yet. Anyone who needs to know about those equations won't need a book this general.
This book is a total missed opportunity, as more on the basics of each topic could have made this book a real winner. Instead, there is a lot of empty space and stuff that is too advanced to make any sense if you've only read what is on the page. If you're a physics student in their third year, this book might be beneficial, but for everyone else, much of it will be too badly explained to be of much use.
