Query: I did not find the "plain English" in this book

I was very disappointed with this book. It is certainly not in plain English, focused way too much on theories and makes it not very approachable. I was hoping to find practical solutions, not some professor talk. To some extent I can only blame myself: only a PhD can write something like that and then put "plain English" in the title. Next time I will make sure I check the author's background first...
