BOSTON -- Nearly 20 years ago, Houghton Mifflin Harcourt’s Nobel Prize-winning author Leon Lederman coined the term “The God Particle” to describe the Higgs Boson, the elementary particle that is crucial to understanding how physical objects exist. This week, Switzerland’s European Organization for Nuclear Research (also called CERN) and Chicago’s Fermi National Accelerator Laboratory have announced the momentous discovery of “The God Particle,” representing a breakthrough in physics after decades of work done by researchers like Lederman around the globe. Lederman’s The God Particle: If The Universe is The Answer, What is the Question? (Houghton Mifflin Harcourt, ISDN 9780618711680) details the development of quantum mechanics, the quest for the Higgs Boson and the desire to understand the most basic elements of our existence. Lederman was for 10 years director of the Fermi National Accelerator Laboratory, one of the centers behind the discovery. Researchers say the announcement is on the scale of the discovery of gravity or the existence of the electron, both which had implications in several different fields.
