Modern Physics: Understanding The Content Taught in the US

The Modern Physics course is a crucial gateway for physics majors, introducing new concepts beyond K-12 experiences. Despite its significance, content varies widely among institutions. This study analyzes 167 Modern Physics syllabi from 127 R1 and R2 US institutions, employing emergent coding on data from public sources (51.5%) and private correspondence (48.5%). Public course catalogs were consulted to identify pre- and co-requisites, with 37.1% of students having completed Calculus II. Foundational topics like Newtonian Mechanics (94%), Electricity and Magnetism (84.4%), and Waves or Optics (77.2%) were frequently required. Quantum Physics (94%), Atomic Physics (83%), and Relativity (70%) were most commonly taught. The study highlights the lack of uniformity in Modern Physics curricula, emphasizing the importance of a consistent and comprehensive education for physics majors across universities. This insight contributes to the ongoing discourse on optimizing physics education in higher education.
