When you read the header to this article, you probably thought I made a mistake. Doesn't he mean atomic force microscope, the familiar AFM? And isn't that microscope in our present, not in our future? Well, I'm not confused. The reference is to a beam of atoms that some day may be used in an atomic microscope, just like a beam of electrons is used in an electron microscope. It would be even more accurate to refer to an “atomic de Broglie microscope,” but that's a rather awkward label.
