The chapter discusses the discovery of the Higgs boson by the Large Hadron Collider, highlighting its significance as a major victory in physics. It also emphasizes the cautionary tale of assuming the discovery of the Standard Model and the need for comprehensive searches and questioning assumptions.', "Lessons from the Large Hadron Collider project illustrate the demonstration of humanity's ability to commit to and achieve grand engineering efforts, as well as the importance of international collaboration in scientific endeavors.
