Somewhat basic and repetetive, but probably good for a complete beginner
on 14 March 2015
This book probably functions as a good introduction to the concept of higher dimensions if you know absolutely zero about the subject. If you've read Abbot's "Flatland" then it's probably not worth delving into this as most of the book is simply rehashing concepts from that - I confess that I got a bit bored with reading about the same idea rephrased in marginally different ways.
In addition the fictional narrative that starts every chapter is somewhat amateurish, and really adds very little to the book - I would rather have read a textbook presented as such than this half-hearted attempt at appealing to the x-files generation.
There's also a rather strange attempt to sell higher dimensions as religious concepts - god as a 4D being, heaven and hell as spaces slightly removed from us in higher dimensions etc. In something that purports to be a textbook I could have done without this. I realise that there has been serious theological and philosophical discussion around these points, but to my mind the author failed to remain unbiased here, which I simply found annoying.
That said, if you really don't know anything about hyperspace or multiple dimensions it's all written in layman's terms and is very easy to understand. In that respect it's probably an excellent place to start, though I imagine that if it catches your interest you'll be wanting to do some wider reading.
One section I did find useful is appendix B - a list of various works of fiction that all contain the context of hyperspace/higher dimensions in some way. While I've already read a lot of the stories listed it did provide me with some useful suggestions that I'll be looking to add to my library.
All in all 2.5 / 5. I've chosen to be generous and round this up to 3 rather than down to 2. Perhaps I should rate it as a quaternion: 2.3 + 3.2i + 1.8j + 2.4k
