In the fall of 2007, when the U.S. economy first seemed in peril, I began answering reader queries here on the Business Desk. I still do so occasionally, but this page has expanded to include posts from eminent economists, "far-flung correspondents," and a variety of voices that have intriguing and/or useful things to say about economics, broadly defined. Please feel encouraged to respond to any and all of them.
Editor's note: On Friday's NewsHour, Paul speaks to Felice Frankel and George Whitesides, authors of an extraordinary new book, No Small Matter: Science on the Nanoscale. Frankel and Whitesides bring the virtually invisible world of nanotech to life through bold and evocative images, often through metaphors that express the structures of microtechnology and how it operates.
