  The Standard Model of particle physics encapsulates our current best
understanding of physics at the smallest distances and highest energies. It
incorporates Quantum Electrodynamics (the quantised version of Maxwell's
electromagnetism) and the weak and strong interactions, and has survived
unmodified for decades, save for the inclusion of non-zero neutrino masses
after the observation of neutrino oscillations in the late 1990s. It describes
a vast array of data over a wide range of energy scales. I review a selection
of these successes, including the remarkably successful prediction of a new
scalar boson, a qualitatively new kind of object observed in 2012 at the Large
Hadron Collider. New calculational techniques and experimental advances
challenge the Standard Model across an ever-wider range of phenomena, now
extending significantly above the electroweak symmetry breaking scale. I will
outline some of the consequences of these new challenges, and briefly discuss
what is still to be found.
