The fine-structure constant is ubiquitous throughout physics. I’ve already noted its connection to the electromagnetic interaction. In atomic physics, the binding energy, fine-structure splitting, and Lamb shift are all proportional to powers of ?�. In condensed matter physics, ?� characterizes Josephson junction oscillations and quantum Hall resistance steps. In addition, ?� is an important component of our system of fundamental constants.
