I am not a scientist. I'm a writer and former actor. But, ever since I was a kid and discovered Scientific American, I've had an abiding interest in science both for the things there are to learn and the recreation that reading science offers. So, I've read a ton of stuff about science.
I have read some books that have knocked me off my feet over the years. But, Warped Passeges knocks their sox off. I admired the book so much that after I read my library copy, I bought it.
The first time I ever heard (outside SF, of course) about dimensions beyond three of space and one of time, was not so long ago when New Scientist did a piece on the idea. The problem was that the article raised too many questions of the wrong kind. What the piece whould have done is deal precisely with the questions that were raised. Those were the simple basic questions. For example, What is a dimension? The answer was not forthcoming in any set of words that made sense.
In Warped Passages, Lisa Randall, not only answered that question but it made sense to me and gave me a good idea of what the teeny, tiny ones are. I could never find anyone to make even the slightest sensible explanation before.
The whole book answers rafts of questions of that nature and a whole lot more as well. I'm grateful to her for that. The book even led to the answer to a question that has bothered me for many years - Why is there only one time dimension?
The answer lies in Randall's field of model making (I didn't even know what model making meant in physics before reading the book) which suffuses her book. For me, it was her historical, beginning, middle, end approach that took me by the hand and led me down a pretty wonderful garden path.
You may not need the most basic questions answered. If so, I suppose you can speed-read those passages. However, I think you will still get a huge amount out of the book.
However, if you are anything like me, you will come out of the other end of the book informed and delighted.
