The search for, and ultimate discovery of, the Higgs boson is a triumph of modern physics—a global, half-century effort whose outcome would make or break the vaunted Standard Model of particle physics. The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was justly celebrated around the world.
And yet, virtually no one who happily read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you truly understand the details, this story ranks as one of the most fascinating, important, and thrilling in the history of modern physics.
