We have confirmed the existence of 17 fundamental particles—12 fermions (matter-builders like quarks and leptons) and 5 bosons (force-carriers like the photon and gluon).
Mediate the fundamental forces (electromagnetism, weak, and strong). Provides the mechanism for mass. The Persistent Mysteries
Drawing heavily from the insights of Nobel laureate in his celebrated book Facts and Mysteries in Elementary Particle Physics , we can explore the subatomic world through a unique lens: one that separates what we experimentally know for certain (facts) from the profound gaps in our understanding (mysteries). The "Actors" and the "Stage"
