Living Physics Portal: Dimensional analysis

Abstract: Dimensional analysis (DA) is a valuable first step in helping students to learn to see equations as something that represents knowledge about the physical world instead of simply as calculations with numbers. We often treat DA as if it’s just unit checks and a way to find calculational mistakes. But it plays a more fundamental conceptual role as a way to help students learn to blend physical concepts with mathematical representations. For pre-meds, the AAMC has identified DA as a primary learning objective in developing quantitative numeracy. These readings help students understand the issues involved.
