In the standard model of particle physics, matter is constructed from elementary constituents called leptons and quarks. In his Perspective, Peskin discusses recent measurements of the mass of one of the most elusive of these--the top quark. Over the past several years, the measurements have permitted better constraints on the mass of the top quark, and it is just the value expected to reconcile data from many studies of the electroweak interaction. Peskin considers the recent results in the light of future searches for another important entity--the Higgs boson.
