Robert Oerter is a theorist who has explored supergravity, especially as applied to string theory, quantum chaos, and underwater acoustics. Currently, he is interested in nonlinear quantum mechanics and quantum computing. His book about the standard model of elementary particle physics, The Theory of Almost Everything: The Standard Model, the Unsung Triumph of Modern Physics, is a non-technical introduction to the most successful physical theory of all time, one that unites our understanding of the structure of matter and (almost) all of its interactions.
