Calling the Higgs boson the “God particle” is a mistake that we need to avoid.
Science is under serious and increasingly successful attack in the US by religious extremists who are concerned mainly with the teaching of biological evolution in public schools but are also generally anti-science and anti-intellectual. The majority of Americans have some religious beliefs that are important to them. I have been speaking to various churches, social clubs, and other groups, trying to explain to them what science is about; why science, correctly understood, does not threaten most people’s religions; and why we can’t afford to teach anything but the best science we know in our schools. I’m not trying to convert extremists. I’m trying to arm reasonable, mostly intelligent but uninformed people against simplistic arguments like “It’s only a theory” or “Why not teach all sides?” They listen to me because I respect their religious beliefs even though I don’t share them. They tune out scientists who offend their religious sensitivities.
We need such people to be our allies. Offending them by using “God” flippantly is just throwing gasoline on a fire. It’s encouraging a fight we cannot win, and we should stop doing it.
