In the photograph on the opposite page we see a single mercury ion held nearly at rest in an electromagnetic “trap.” Physicists have seen individual atoms before, in arrays imaged by field ion microscopes and more recently by vacuum tunneling microscopes, but what we see here is different. It graphically demonstrates a physicist's ideal: holding a single isolated atom nearly at rest for careful examination.
