<div>Mathematicians love theorems; experimental scientists love
predictions. Can theorems ever make testable predictions? The
answer is yes. In this talk, we discuss one powerful kind of
predictive theorem (classification of representations). For
example, from the basic principles of quantum mechanics and the
inherent spherical symmetry of the hydrogen atom it is possible to
predict much of the electronic structure of the hydrogen atom. This is
not an isolated example; rather, it is a simple case of a wide-ranging
method.</div>
