If you have a copy of my book, you have a chance to do the world (and me) a favor.
Go onto Amazon, and review it -- please.
It has exactly one review, and that's from a guy who's disgruntled that the book doesn't cover formal robust control theory. While I understand his disappointment to some extent, you can't really approach that topic unless you've got at least four years of a math-intensive engineering education behind you; it's certainly not a topic that I could make both accessible and useful to a general audience, and I don't think that anyone else could, either.
It would be like me getting bent out of shape because I bought a book called "Practical Pottery from Clay to Cup" that didn't show me how to make an accurate reproduction of a Ming vase or a set of matching decorated china dishes.
His is the only feedback I've gotten on the book that could be summed up as "it totally sucks" -- yet it's the only feedback _at all_ on Amazon.
I know that there's people out there who like the book far more -- if you're one of them, or even if you're only mildly thrilled with it, you can give people more complete and accurate information than they have now by getting on there and giving it a review.
Thanks in advance.
