The Nobel Prizewinning physicist Leon Lederman guides readers on an enormously accessible tour of the history of particle physics, from the Greeks" earliest scientific observations through Einstein and beyond. He takes us on the quest for the Higgs boson, nicknamed the God particle, which will help unlock the last secrets of the subatomic universe. In the new preface for this edition, Lederman explains some of the up-to-theminute advances in supercollider research that are bringing answers ever closer.
