# Paul Dirac British theoretical physicist whose 1928 equation unified [[Quantum Mechanics]] with special relativity, producing Quantum Spin as a mathematical necessity and predicting antimatter four years before it was observed. A founder of Quantum Field Theory. Nobel Prize in Physics, 1933. Dirac's observation that the underlying laws of chemistry were now completely known and only the equations were too hard to solve remains the standing case for quantum simulation as the most credible near-term application of [[Quantum Computing]].
