The God Particle: If the Universe Is the Answer, What Is the Question? is a 1993 popular science book by Nobel Prize-winning physicist Leon M. Lederman and science writer Dick Teresi. The book provides a brief history of particle physics, starting with the pre-Socratic Greek philosopher Democritus, and continuing through Isaac Newton, Roger J. Boscovich, Michael Faraday, and Ernest Rutherford and quantum physics in the 20th century. Lederman explains in the book why he gave the Higgs boson the nickname "The God Particle": "This boson is so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive, that I have given it a nickname: the God Particle. Why God Particle? Two reasons. One, the publisher wouldn't let us call it the Goddamn Particle, though that might be a more appropriate title, given its villainous nature and the expense it is causing. And two, there is a connection, of sorts, to another book, a much older one..."

• p. 22 In 2013, subsequent to the discovery of the Higgs boson, Lederman co-authored, with theoretical physicist Christopher T. Hill, a sequel: Beyond the God Particle which delves into the future of particle physics in the post-Higgs boson era. This book is part of a trilogy, with companions, Symmetry and the Beautiful Universe and Quantum Physics for Poets (see bibliography below).

Historical context

Fermilab director and subsequent Nobel physics prize winner Leon Lederman was a very prominent early supporter – some sources say the architect or proposer – of the Superconducting Super Collider project, which was endorsed around 1983, and was a major proponent and advocate throughout its lifetime. Lederman wrote his 1993 popular science book – which sought to promote awareness of the significance of such a project – in the context of the project's last years and the changing political climate of the 1990s. The increasingly doomed project was finally shelved that same year after some $2 billion of expenditure. The proximate causes of the closure were the rising US budget deficit, rising projected costs of the project, and the cessation of the Cold War, which reduced the perceived political pressure within the United States to undertake and complete high-profile science megaprojects.
