High school students interested in mechanical engineering are encouraged to explore foundational books that provide a broad understanding of the field. Recommendations include "Structures, or Why Things Don't Fall Down" by J.E. Gordon, which offers basic insights into engineering concepts. It's important for students to focus on math skills, as engineering relies heavily on mathematical analysis. The discussion highlights the diverse areas within mechanical engineering, such as design, analysis, and production, suggesting that students refine their interests as they progress. Engaging with various resources and university research can further enhance their understanding of the discipline.
