I'm taking notes on a book I'm reading right now (and more on the book later). The current heading is "Making Visible the Invisible," but I typed it "Making the Visible Invisible," thus reversing the meaning. And it struck me that the error might make a good lesson in a first year grammar-based discussion to illustrate the importance of clarity (and articles), and the use of nouns and adjectives. Something to remember for next term if I'm stuck teaching the non-English based English courses again.
*EDIT: fixed the second statement by switching the visible/invisible order.
