Words can be slippery suckers.

Yes, I knew your question was genuine and in no way did I see it as antagonistic.

My answer was a little bit tongue in cheek, but not entirely. I did have a copy of the book at one stage, but don't now. I rely on quotes from others at ISG. The biggest problem I had (past tense) was that as a physics and applied mathematics teacher of many years I kept reading things that my training and experience told me were gobbledegook. People would try to explain (there's quite an enthusiastic TGM following on ISG), and that would be fine for a while, but then I'd see something else that didn't make sense.

When birdie_man quoted a video posted here I followed, and lo and behold there were my words, so I jumped in. After the exchanges I mentioned with yoda and ThinkingPlus I looked at the frame of reference issue again and a light went on.

As a result, so many of the things that looked like gobbledegook didn't look like gobbledegook any more. Rather than explaining how the throw out effect works in inertial physics (which was my intention), it hit me that Mr Kelley was describing things in very particular frames of reference.

So to answer your question directly, no I don't understand the book, but I'm miles further down the path than I was when I arrived here.

Good to hear it!thanks
