You guys ever watch Alton Brown? His entire stock and trade is in food science -- basically his entire program is based on the premise that you get where you're going faster by understanding the underlying theory of cookery.
Agreed!

I've read the article more carefully now so here are my (updated) thoughts

I'm actually going through this with my boyfriend right now, he's not a "natural" cook, and he seems actually nervous and almost scared of cooking, which is weird as he's so practical in every other aspect of his life.
So I'm teaching him basic techniques (how to make a white sauce, how to tell when meat is done) and I'm teaching him about the science (which he knows anyway but not when applied to food for some reason, we're both generally sciency, I took a physics degree, he's engineering) like why he should put the salt in boiling water not in cold water, what ingredients will neutralise acidity,why he shouldn't add oil to cooking pasta, adding sugar to onions, salt in baking, all that kind of stuff. The ratio stuff is one step further, like knowing how much stock to risotto rice you need, or pastry is x part fat to x part flour.
It's not everything though, I also want him to be able to taste stuff and go "oh, it's too.... I need to..." which I think is really important in cooking. I think there's only experience which will teach him that, and following recipes is a good way of learning those combinations and quantities.
For instance, my db had no idea that apples and pork are a good match, or really even tomatoes and basil, citrus and corriander, let alone more "out there" stuff, my chocolate and lavender tart was really interesting to him,the combination of ratio knowledge with flavour combination knowledge would leave you a really open playing field to create your own dishes.
I think the book sounds really interesting, and of course the "throw out your cookbooks" thing is a bit of hyperbole, no one is suggesting that's done for a myriad of reasons but I think these techniques are interesting and important and can help you be more creative by doing the ground work for you.
I think I'll get him a copy!
