Revolutionary new concepts about elementary particles, space and time, and the structure of matter began to emerge in the mid-1970s. Theory got far ahead of experiment with radical new ideas, but the concepts have never been experimentally tested. Now all that is about to change. The LHC — the Large Hadron Collider — has finally been built and is about to confront theory with experiment. The final quarter of our ongoing physics series with Leonard Susskind is devoted to supersymmetry, grand unification,
and string theory.
